Abstract
Purpose This study aimed to report the outcomes of hypospadias repair performed at a tertiary-level hospital during 2018 to 2021. Methods A retrospective chart review of 119 patients was performed. Results The most frequent coronal hypospadias cases were distal. However, the most common scrotal hypospadias cases were proximal. The average age at the time of the first surgery was 2.4 years (standard deviation, ±2.3 years). The tubularised incised plate technique was performed for 57 of these 119 patients. Urethral fistula was the most common complication associated with distal and proximal cases (23.96% and 30.43%, respectively). No significant correlation was observed between any complication and the surgical technique. Based on the logistic regression model, the duration of urethral stenting was statistically significant (p=0.025), indicating that a urinary catheter duration of more than 5 days resulted in a 2.9-times increased risk of postoperative urethral fistula. Conclusion Prolonged urethral stenting for more than 5 days may result in subsequent urethral fistula development. Neither the severity of hypospadias nor the surgical technique seems to affect postoperative complications.

Modified PATIO technique for urethrocutaneous fistula after hypospadias repair: Experience from a tertiary referral hospital. J Pediatr Urol 2024:S1477-5131(24)00072-X. [PMID: 38369430 DOI: 10.1016/j.jpurol.2024.01.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 01/15/2024] [Accepted: 01/31/2024] [Indexed: 02/20/2024]
Abstract
INTRODUCTION Urethrocutaneous fistula (UCF) is a common complication after hypospadias repair with an incidence of 5-10%. Several techniques are described for its repair: small UCFs are frequently corrected by isolation, excision, and closure with apposition of a protective second layer. In 2008 Malone described the PATIO technique: the fistula tract is turned inside out in the urethral lumen preventing contact with passing urine without direct urethral sutures. OBJECTIVE Aim of our study is to present our outcomes using a modified version of the PATIO technique, with a more reproducible isolation of the tract and without its fixation at the urethral meatus. STUDY DESIGN We retrospectively reviewed all cases of UCFs corrected with a modified PATIO technique at our center between 2016 and 2020. Data collected from electronical clinical notes were age at UCF closure, location of UCF, presence of meatal stenosis and clinical outcomes. Data are presented as median and IQR. RESULTS In the study period we performed 425 urethroplasties for distal and mid penile hypospadias. The incidence of UCFs was 7% (30/425) and 25 patients underwent UCF correction with modified PATIO. Median age at repair was 4.5 years (IQR: 2.5-6.2). At a median follow-up of 3 years (IQR: 2-4) recurrence was observed in 5 cases out of 24 with one patient who was lost at follow-up (20.8%). One case was corrected successfully with re-do modified PATIO technique, while 4 are awaiting repair. One cases was lost at follow-up. UFC-recurrence was homogeneously distributed along the study period. DISCUSSION Risk factors for UCF recurrence are mostly the type of hypospadias, neo-urethral length, and quality of the urethral plate. Among the many existing techniques, we propose a modified version of Malone's PATIO repair. We believe that the use of four stay-suture to isolate the fistula allows a well-defined dissection of the tract along its surface, compared to the use of a single stay-suture. In our experience, there is no need to keep and fix the traction on the fistula tract to the urethral meatus, probably reflecting the efficacy of the fistula closure during the introflection, which is then maintained without traction. Limitations to our study include the retrospective nature of the review, the small sample size of the cohort and the absence of control groups. CONCLUSIONS Our results appear consistent with literature regarding the efficacy of PATIO principles in treating UCF. Modified PATIO seem to be particularly reproducible, showing encouraging results.

Abstract
INTRODUCTION Tubularized incised plate urethroplasty (TIPU) surgery is among the most successful techniques for distal hypospadias. Our objective was the investigation of complication rates and their predictors. METHODS Between 2010 and 2021, 150 patients with distal hypospadias were operated on consecutively by a single surgeon using the TIPU technique. The primary outcome was the complication rates including fistula, meatal stenosis, and glans dehiscence. Secondary outcomes were predictor factors of complications. RESULTS The average glans diameter was 13.9 ± 0.10 mm and 57.0% of the patients had a glans diameter greater than 14 mm. Single-layer and double-layer urethroplasty were used in 55.3% (n = 83) and 44.7% (n = 67) of patients, respectively. Overall complication rate was 23.3% (n = 35), which included fistula (3.3%, n = 5), glans dehiscence (12.7%, n = 19), and meatal stenosis (8.6%, n = 13). Glandular meatus localization (OR = 58.8, p = 0.001) and smaller glans diameter (OR = 0.39, p = 0.001) were significant predictors in the multivariate analysis of overall complications. For fistula complications, only short operation time (OR = 0.83, p = 0.03) was found as a significant predictor. Glans width (<14 mm) was the only significant predictor of both glans dehiscence (OR = 3.4, p = 0.03) and stenosis (OR = 5.67, p = 0.013) complication. CONCLUSION TIPU technique for distal hypospadias has notable success and acceptable complication rates. Dartos augmented single-layer urethral closure seems adequate for complication prevention. Preoperative assessment of the glans width and meatus site is advised to predict complication rates.

Biologic adjuvant urethral coverings for single-stage primary hypospadias repairs: A systematic review and pooled proportional meta-analysis of postoperative urethrocutaneous fistulas. J Pediatr Urol 2022; 18:598-608. [PMID: 36085187 DOI: 10.1016/j.jpurol.2022.08.015] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Revised: 08/09/2022] [Accepted: 08/16/2022] [Indexed: 12/14/2022]
Abstract
BACKGROUND The use of barrier layers between the neourethra and skin is associated with lower rates of post-operative urethrocutaneous fistula (UCF) following hypospadias surgery. Recent studies have evaluated the ability of biologic adjuvant urethral coverings (BAUCs) - namely acellular matrix (AM), tissue adhesives (TAs), and autologous platelet-rich plasma or fibrin (PRP/PRF) - to prevent wound complications following hypospadias surgery. In general, however, these studies are small and conducted at single institutions. OBJECTIVE To assess the effect of BAUCs on the rate of UCF following single-stage primary hypospadias repair. METHODS We conducted a systematic review of studies reporting the rate of postoperative UCF in pediatric patients undergoing single-stage, primary hypospadias repairs using either AM, TA, or PRP/PRF as a layer interposed between the neourethra and skin. We then performed a pooled proportional meta-analysis of post-operative UCF. Patients within each study who underwent comparable surgery but did not receive a BAUC were used as controls. RESULTS 10 studies were included in our review. The meta-analysis included 280 patients from 7 studies who underwent hypospadias repairs with BAUCs. The pooled incidence of UCF was 10% (95% CI 6-14%). Mean follow-up ranged 5-23.5 months in the 5/7 studies reporting specific durations, and ≥6 month and 14-30 months, respectively, in the other two studies. Patients in whom a BAUC was used had significantly lower odds of UCF than control patients (OR 0.39, 95% CI 0.24-0.64, p = 0.0002). In subgroup analyses, significant superiority held for AM and TA; proximal or penoscrotal cases; transverse preputial island flap (TPIF) technique; when both cases and controls had local flaps; and when neither cases nor controls had flaps. DISCUSSION The use of BAUCs was associated with decreased rates of post-operative UCF in single-stage primary hypospadias repairs and may be most beneficial in more severe cases and when used in addition to local flaps or when using a flap is not possible. In 2/3 studies of PRP/PRF and 2/4 studies of tubularized incised plate (TIP) technique, dartos flaps were used in controls but not BAUC patients, which may explain the lack of benefit demonstrated for these subgroups. This meta-analysis is limited by the quality of evidence in the included studies, which are not uniformly randomized. Furthermore, the follow-up durations and methods for assessing complications are not standardized between included studies. CONCLUSION The meta-analysis herein suggests that using BAUCs may reduce UCF rates following hypospadias surgery. Rigorous prospective evaluation is needed to validate this benefit.

Referral patterns, clinical features and management of uncorrected hypospadias in a series of adult men. J Pediatr Urol 2022; 18:480.e1-480.e7. [PMID: 35773150 DOI: 10.1016/j.jpurol.2022.06.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/21/2022] [Revised: 05/27/2022] [Accepted: 06/03/2022] [Indexed: 10/18/2022]
Abstract
BACKGROUND Hypospadias surgery undertaken in early life often continues to impose challenges as patients age. Little is known about the natural history of uncorrected hypospadias persisting into adulthood. OBJECTIVE To describe presenting symptoms and management strategies in men with uncorrected hypospadias referred to our national tertiary transitional clinic for congenital urological conditions. MATERIALS AND METHODS Patients with uncorrected hypospadias older than 16 years at the time of referral were identified by searching the electronic patient record system for ICD-10 hypospadias codes. Data were extracted over a 10-year period according to a predefined protocol. RESULTS Among 201 referrals, 65 men with hypospadias (glanular n = 12, coronal n = 26, subcoronal n = 9, corporal n = 4, penoscrotal n = 2 and MIP n = 12) had never previously had reconstructive surgery undertaken. Obstructive symptoms predominated (n = 30) and the risk of symptoms increased with advancing age (Figure). Presenting complaints varied across the age span; cosmetic issues (n = 11) and coital pain (n = 5) were primarily seen in youth as opposed to urinary obstructive symptoms that were increasingly more frequent with age (p = 0.002) (Figure). Management included reconstructive surgery (n = 24), minor procedures (preputioplasty, circumcision, meatoplasty, dilatation/urethrotomy, total n = 28) as well as counselling (n = 12). The management strategies were independent of age and hypospadias type. DISCUSSION The current cohort delineates the dynamic nature of hypospadias in itself. We speculate that the distinction in the primary complaint leading to referral between the extremes of age may relate to the vanity and insecurity of youth while older patients first come forward when other symptoms arise. Dissatisfaction with genital appearance is uncommon in previous smaller studies on men with uncorrected hypospadias unlike in our study, where 11 patients were assessed mainly for cosmetic concerns. Obstruction is the main symptom encountered in adult hypospadias patients operated in early life, and a similar picture was observed in our cohort of unoperated cases. Urethral dilatation and internal urethrotomy are temporizing procedures but were successful in immediate alleviation of obstructive symptoms in patients not willing to consign themselves to formal surgery. The study is limited by its retrospective design, and our symptomatic cohort may also represent the extreme end of the hypospadias spectrum. CONCLUSION Medical issues vary across the age span in men with unrepaired hypospadias. Minor surgical procedures as well as counselling play an equally important role as reconstructive hypospadias surgery in the management of unrepaired hypospadias in adulthood.

Abstract
OBJECTIVE To describe standard and modified de-epithelialized Byars' flap techniques in tubularized incised plate urethroplasty and evaluate postoperative outcomes. METHODS We retrospectively evaluated data for 404 primary hypospadias repair patients who underwent standard (Group A) or modified (Group B) urethroplasty between January 2016 and 2021. Group B's data were analyzed to evaluate whether our modified technique was effective for all hypospadias types. RESULTS There was no difference in the ratio of different hypospadias types between Groups A (n = 145) and B (n = 259). Median follow-up duration was 35 months. Fistula occurred in 19 patients in Group A and 12 in Group B (statistically significant difference). The total complication rate was statistically significantly different between the groups. In Group B, 3/142 patients with distal hypospadias developed urethrocutaneous fistula vs 4/95 with mid-shaft hypospadias and 5/22 with proximal hypospadias. No difference was noted between the distal and mid-shaft groups. Significant differences were observed when comparing distal and mid-shaft groups with the proximal group; total complication rates were similar. Glans dehiscence and meatal stenosis rates were similar between Groups A and B, and among the hypospadias phenotypes. CONCLUSION Our modified procedure is simple to perform and yields excellent results in distal and mid-shaft hypospadias repair.

Abstract
AIM We have previously employed the tubularized incised plate (TIP) repair technique in distal hypospadias cases with a few modifications because of its excellent cosmetic results. In this study, we aimed to evaluate the effects of spongioplasty and dorsal dartos flaps, in addition to short urethral stents on the outcomes of TIP repair. MATERIALS AND METHODS Only distal hypospadias cases were involved in this study. Eligible patients were divided into two groups: group A included patients repaired with both spongioplasty and dorsal dartos flap placement, while group B included patients repaired with dorsal dartos flap placement alone. Group A was further divided into two subgroups according to the type of catheter used (bladder catheter or short urethral stent). RESULTS A total of 473 patients were included in this study. There was no statistically significant difference observed in the complication rates between the two groups. In Group A, a bladder catheter was used in 107 patients and a short urethral stent was used in 135 patients. When the results of the two groups were compared, there was no statistically significant difference. CONCLUSIONS Spongioplasty could be combined with dorsal dartos flap placement to reduce the need for dorsal plication rather than to reduce the fistula rate. Short urethral stents can be used safely with no postoperative effects in children who have completed toilet training.

Abstract
INTRODUCTION Recent investigations have raised a doubt regarding the safety of Caudal epidural block (CEB) administered to children with distal hypospadias undergoing tubularised incised plate (TIP) urethroplasty. The primary objective of the study was to investigate whether there is any association between CEB and the occurrence of urethrocutaneous fistula (UCF) in the postoperative period. METHODS Fifty ASA 1 and 2 children with distal hypospadias aged 0-8 years were randomly allocated to CEB group (GA with CEB, 0.2% ropivacaine 1 ml/kg; n = 25) and Non-CEB group (GA without CEB; n = 25). Penile measurements were taken before and 20 min after administration of CEB to assess penile engorgement. Intraoperative hemodynamics were recorded at 10 min intervals after induction of anaesthesia. Consumption of IV fentanyl intraoperatively and postoperatively in first 24 h was recorded in both the groups. Rescue analgesia was administered for a score >4 on FLACC scale. After surgery children were followed up monthly for first three months and then at 6-months and yearly in paediatric surgery OPD to assess for development of UCF. RESULTS UCF was found to occur in only two children, one from each group on follow up, with an overall incidence of 4%. There was no difference in the incidence of UCF in the patients with and without CEB. A 26.8% increase in penile volume from baseline was recorded in CEB group (P = 0.000). The intraoperative heart rate and mean arterial pressure was significantly lower in the CEB group as compared to non CEB group at various time intervals. No additional intraoperative IV fentanyl supplementation was required in CEB group. Fentanyl consumption was significantly less in CEB group postoperatively in first 24 h (P = 0.000). DISCUSSION Administration of CEB was not found to have any impact on UCF formation. No relationship between the increase in penile volume after CEB block and occurrence of UCF was noticed. CONCLUSION Despite increase in penile volume after CEB, there was no difference between the two groups as regards to the occurrence of post operative UCF. CEB is an effective analgesic modality and can be continued to be used till the results of well powered prospective randomised trials with long follow up are reported.

Abstract
INTRODUCTION Distal hypospadias is a common anomaly. Different surgical techniques have evolved through the years to manage this anomaly. Several factors may affect the prognosis. One of them is glans size. We compared the hybrid Mathieu urethroplasty (HMU) and the tubularized incised plate urethroplasty (TIPU) for the management of distal hypospadias with a small glans. METHODS Sixty-eight patients with distal hypospadias were included and categorized into two groups. Group A (n = 33) and group B (n = 35) patients were treated by HMU and TIPU, respectively. All patients had a small glans. In group A, the patients underwent Mathieu urethroplasty plus a deep incision of the urethral plate. In group B, the patients underwent TIPU. Urethral stents were used in all cases. Hypospadias objective score evaluation (HOSE) was used to assess the results. RESULTS Urethrocutaneous fistulae developed in two cases in group A and six cases in group B. Meatal stenosis was significantly lower (one case in group A vs. eight cases in group B). Glanular dehiscence occurred in two cases in group A and five cases in group B. The small glans strongly correlated with the development of both urethrocutaneous fistulae and meatal stenosis where the odd ratios were 3.500 (1.383-7.879) and 9.481 (1.114-12.669), respectively. CONCLUSION Both techniques showed efficacy during management of patients with a small glans. HMU had better outcomes, shorter duration of stent and lesser incidence of complications than TIPU. Small glans was significantly related to urethrocutaneous fistulae and meatal stenosis in group B.

Abstract
Aims We compared the outcomes of unstented repair (UR) versus stented repair (SR) in patients with mid-shaft to coronal hypospadias (HS) to elucidate if SR has any advantage over the UR. Materials and Methods: We retrospectively studied our mid-shaft to coronal HS repair patients between January 2013 and January 2018. We recorded variables such as degree of HS, age at repair, surgeon, type of repair, suture used, stent usage, and standard early and late complications. Relative risk (RR) was calculated and P < 0.05 was considered significant. Results: We included 120 patients (63 UR, 57 SR). There was no statistically significant difference in any parameters in both the groups. All had either tubularized incised plate or Thiersch–Duplay procedure. Urethroplasty was done with PDS 6/0 in all cases. Trainees performed two-third of the repairs under variable supervision. Early complications included one UR patient having urinary retention needing insertion of urethral catheter, five SR patients having bleeding/swelling, and three UR having dysuria. All were managed conservatively. For late complications, 98 patients were available (UR: 51, SR: 47) with fistula in 17 (17.3%), UR 8 (15.6%) versus SR 9 (19.1%) (P = 0.5, RR = 1.2) meatal stenosis in 3, UR 3 versus SR 0 (P = 0.06, RR = 6.4) and glanular dehiscence 6, UR 4 versus SR 2 (P = 0.25, RR = 1.8). Conclusion: There were no statistically significant differences in the short-term complications between UR and SR for HS. In the long term, RR for meatal stenosis is higher in UR.

Abstract
BACKGROUND Pediatric Urology deals with genitourinary diseases. Present study aimed to collect the top-cited article in Pediatric Urology in order to define the most debated and studied topics. METHODS The journals reported in "Urology & Nephrology" category of the 2019 edition of Journal Citation Reports, together with the most relevant journals of "Transplantation," "Pediatrics," and "Surgery" categories, were browsed. The articles of interest in Pediatric Urology with more than 50 citations were collected. A bibliometric analysis was performed to collect the top 100 cited articles. RESULTS The top-cited articles were published in 27 journals (23%), with a median impact factor of 2.676 (IQR 1.981-5.642). Seventeen of them (63%) belonged to "Urology and Nephrology" category. The median number of citations was 82 (IQR 64-113). The most productive journal, with 23 articles, was "The Journal of Urology." Forty-eight top-cited articles were Guidelines or Reviews of the literature and only four papers were randomized controlled trials. The most relevant topic was "congenital anomalies" with 18 articles. As to minimally invasive surgery, eight studies were identified. All of them dealt with robotic-assisted laparoscopic surgery. Two articles reported the current evidence about transitional care. CONCLUSIONS The top-cited articles were dispersed among journals of different areas. Current scientific literature deal with congenital anomalies, more specifically with obstructive uropathies and hypospadias. In the last decade, one of the most relevant innovation in pediatric urology was the introduction of robotic surgery. Transitional care has become a timely topic.

Abstract
Abstract
Background
Several preoperative factors affect the outcome of Tabularized Incised Plate (TIP) repair. Our aim was to collect and analyze all these factors to define what the most important predictive factors are.
Methods
Hundred patients (1–5 years old) with primary distal hypospadias were included. Exclusion criteria included previous penile operations and hormonal treatment or associated congenital anomalies. Anogenital distance (AGD), stretched penile length (SPL), meatal site, glanular shape, chordee and torsion degree, plate width and glans meatus shaft (GMS) score were assessed. TIP repair was done to all patients and followed up for one year. The outcome was correlated with the above parameters.
Results
Mean ± SD of age of patients was 3.5 ± 1.5 years, while weight was 14.1 ± 3.0 kg. Complication rate was 18% including urethrocutaneous fistula (UCF) and meatal stenosis 14%, repair breakdown 1% and urethral stricture 3%. Patients with chordee degree < 30° and distal penile meatal location were associated with increased risk for complications by 11.6 and 8.2 times; 95% CI was (1.46–91.75) and (1.02–66.52), respectively (p < 0.05 for each). Plate width ≥ 9 mm, AGD > 5 cm, GMS score ≤ 7 (p < 0.001 for each), age of patient ≤ 2 years old, and SPL > 3.5 cm (p < 0.01 for each) were associated with successful outcome of repair.
Conclusion
The proposed successful criteria of TIP repair were absent chordee, coronal/subcoronal penile meatal location, plate width ≥ 9 mm, AGD > 5 cm, age of patient ≤ 2 years old, GMS score ≤ 7, SPL > 3.5 cm and grooved glanular shape.

J Pediatr Urol 2021; 17:690.e1-690.e6. [PMID: 34158249 DOI: 10.1016/j.jpurol.2021.06.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/16/2021] [Revised: 05/07/2021] [Accepted: 06/01/2021] [Indexed: 11/26/2022]
Abstract
INTRODUCTION Distal hypospadias represent the most frequent clinical presentation of hypospadias. In spite of more than 300 techniques available, there is not an ideal approach. We have proposed an alternative procedure based on the combination of minor urethral mobilization and major glans deconstruction and partial disassembly from the corpora, the GUD technique. We want to present our clinical experience with the procedure and describe it in detail. METHODS The technique consists of disconnecting the spongious tissue and the distal urethra from the corpora and detaching partially the glans as well, from 2 to 10 o'clock. The glans is opened in midline and the procedure combines cranially mobilization of urethra with caudal and medial rotation of glans wings to refurbish the glans correcting the hypospadia without urethroplasty. RESULTS We have treated 164 patients with distal hypospadia. Median age at the surgery was 22.4 months (1-184 months). The meatal position after penile degloving was coronal at 108 cases, subcoronal at 54 and 2 patients presented megameatus and intact foreskin. Three patients (1.8%) had mild penoscrotal transposition in addition to hypospadia. Twenty-eight patients were treated as a secondary repair (17%). We found complications in 6 patients (3.6%) consisting of five fistulas (3%) and three glans dehiscence (1.8%). Two patients had both complications. Follow up was 21 months (1-42 months) and the median follow-up time was 18 months. DISCUSSION We acknowledge that this procedure is intended only to distal hypospadias (coronal and subcoronal). We stress that the GUD procedure can be performed irrespectively of any urethral plate "quality" as it does not require a minimum glans width as the TIP repair. Moreover, there is no need for preoperative testosterone treatment. The absence of suture and urethroplasty minimizes the risk of coronal fistulas after surgery. CONCLUSIONS We believe that this procedure is a viable alternative to distal hypospadias repair.

Abstract
Background Distal hypospadias repair is one of the most frequent surgical interventions in the pediatric age group. Successful hypospadias repair should provide a functional penis and good cosmetic results. Mathieu urethroplasty is one of the most popular techniques used. The authors aimed at performing a modification that expanded the scope of indications and improved the final cosmetic results of classic Mathieu urethroplasty. Methods Forty-three patients with distal hypospadias were operated by hybrid Mathieu urethroplasty (HMU) during the period from March 2012 to December 2020. All cases had small size glans. Creation of the perimeatal-based flap was performed as Mathieu disrobed. This was followed by the development of glanular wings. The additional step was deep incision of the urethral plate. Then, urethroplasty was performed. The catheter was left in place for 1–3 days. Results The mean age was 1.5 years, and the mean operative time was 67 minutes (60–75 minutes). The mean size of glans was 12 mm (10–15 mm). Fistula developed in three cases. No stricture or meatal regression developed. Infection with disruption of repair occurred in one case. Conclusion Hybrid Mathieu urethroplasty represents a reliable and successful solution for the cases of distal penile hypospadias with small glans and shallow urethral plate. It increases the scope of candidates of the Mathieu procedure, improves the final cosmetic results and has a reasonable rate of complications.

[PMID: 33246830 DOI: 10.1016/j.jpurol.2020.11.010] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2020] [Revised: 11/02/2020] [Accepted: 11/05/2020] [Indexed: 11/16/2022]
Abstract
INTRODUCTION Complications remain the top evaluation priority subsequent to hypospadias repair. Complications vary in further management, and usually require one or more reoperations. Patients and/or their parents concern not only with the success rate of reoperation, but also with the risk of numerous reoperations. OBJECTIVE To identify the risk factors associated with numerous reoperations following primary hypospadias repair. STUDY DESIGN Data were collected retrospectively from patients who underwent reoperations for complications following primary hypospadias repair at a single institution from August 2008 to October 2017. RESULTS A total of 507 patients required reoperations following 2754 primary hypospadias repairs. Eventually, 486 patients were eligibly included with a median age of 2.2 years. The median follow-up period was 6.5 years. Preserved urethral plate urethroplasty for primary repair (including Snodgrass, Onlay and Mathieu techniques) was performed in 307 (63.2%) patients, Duckett technique was performed in 121 (24.9%) patients, and staged urethroplasty (including staged Duckett, Byars and Bracka techniques) was performed in 58 (11.9%) patients. The complications included 302 fistulas, 108 dehiscence, 50 urethral strictures, 18 meatal stenosis, 38 diverticula, 24 mild recurrent ventral curvature and 23 severe recurrent ventral curvature. A total of 363 (74.7%) patients needed 1 reoperation, 87 (17.9%) needed 2 reoperations, 19 (3.9%) needed 3 reoperations, and 17 (3.5%) needed >3 reoperations. Ordinal logistic regression demonstrated that severe recurrent ventral curvature, urethral stricture, dehiscence and primary staged hypospadias repair increased the risk of numerous reoperations, with odds ratios of 75.991-fold, 36.967-fold, 11.765-fold and 3.074-fold, respectively. In contrast, diverticulum decreased the risk, with an odds ratio of 0.443-fold. DISCUSSION Our data demonstrated significant heterogeneity in the risk of numerous reoperations for each complication. Severe recurrent ventral curvature conferred the highest risk of numerous reoperations, followed by urethral stricture, dehiscence. In additional, our data showed an increased risk of numerous reoperations following primary staged repairs. Identification the risk factors confers advantages in the assessment of postoperative outcomes and anticipation of future reoperations. CONCLUSION Severe recurrent ventral curvature, urethral stricture, dehiscence and primary staged hypospadias repair were associated with numerous reoperations following primary hypospadias repair.

[PMID: 32439182 DOI: 10.1016/j.jpedsurg.2020.03.013] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2020] [Revised: 03/10/2020] [Accepted: 03/20/2020] [Indexed: 11/29/2022]
Abstract
PURPOSE We conducted this meta-analysis to compare postoperative outcomes between meatal-based flap (Mathieu) and tubularized incised plate (TIP) techniques for distal hypospadias. METHODS A comprehensive literature search of PUBMED, Web of Science, EMBASE, and Cochrane Library was conducted. Outcomes evaluated in this review were fistula, meatal stenosis, wound dehiscence and flap necrosis. We calculated odds ratio (OR) with 95% confidential interval (CI) to compare postoperative outcomes between Mathieu and TIP after data extraction and literature identification. All data were analyzed using Review Manager 5.2. In order to find potential affective factors, meta-regression and subgroup analyses were applied. RESULTS 16 studies, 1386 patients, including 762 patients receiving Mathieu and 624 individuals subjected to TIP met the inclusion criteria. The synthetic data suggested that Mathieu and TIP were comparable in terms of fistula (OR = 0.93; 95% CI: 0.65 to 1.33; P = 0.70, I2 = 14%), wound dehiscence (OR = 0.89; 95% CI: 0.33 to 2.39; P = 0.81, I2 = 11%), and flap necrosis (OR = 1.9; 95% CI: 0.51 to 7.09; P = 0.20, I2 = 38%) without significant heterogeneity for each comparison group. Pooled estimates showed a significantly lower rate of meatal stenosis with Mathieu than with TIP (OR = 0.41; 95% CI: 0.24 to 0.73; P = 0.002, I2 = 4%). Subgroup analyses showed that the difference between Mathieu and TIP was more obvious in the studies published before 2013 in meatal stenosis. The modified Mathieu technique and a running suture for urethroplasty might be relevant to a lower rate of meatal stenosis in the data, although no statistical significance in the present effects model overall was found. One-way sensitivity analysis showed that the results were stable. There was no publication bias detected using both funnel plot and Egger's test. CONCLUSION This meta-analysis suggested that Mathieu and TIP technique were equivalent for primary distal hypospadias in terms of fistula, wound dehiscence, and flap necrosis. Pooled estimates indicated that there was a lower rate of meatal stenosis with Mathieu rather than with TIP significantly. The modified Mathieu technique and a running suture for urethroplasty might be relevant to a lower rate of meatal stenosis. TYPE OF STUDY Meta-analysis. LEVEL OF EVIDENCE IV.

Nonstented Tubularized Incised Plate Distal Hypospadias Repair: A Single Center 5 Years' Experience. Urology 2020; 146:207-210. [PMID: 32822686 DOI: 10.1016/j.urology.2020.08.014] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2020] [Revised: 08/01/2020] [Accepted: 08/09/2020] [Indexed: 11/23/2022]
Abstract
OBJECTIVES To report our immediate and delayed outcomes of nonstented tubularized incised plate (TIP) distal hypospadias repair. METHODS We retrospectively reviewed all charts of children who underwent distal hypospadias repair in a single children's hospital from 2013 to 2018. Patients' demographics, hypospadias characteristics, operative technique, and immediate and delayed outcomes were recorded. RESULTS Of 280 consecutive distal hypospadias repairs that were identified, 74 were excluded due to the use of a repair other than TIP. Eleven stented TIP repairs were excluded as well. Of 195 nonstented repairs, immediate postoperative voiding complications were recorded in 11 (5.6%) and included multiple/split stream in 6 (3%), dysuria and voiding difficulty in 2 (1%), urinary retention in 2 (1%), and gross hematuria that spontaneously resolved in 1 (0.5%). Late follow up was recorded in 142 of 195 (72.8%) repairs. Delayed urethroplasty/glansplasty complications were recorded in 12 (8.5%) and included urethrocutaneous fistula in 10 (7.0%), meatal stenosis in 6 (4.2%) and glans/urethroplasty dehiscence in 2 (1.4%). CONCLUSION Avoiding postoperative urethral stents in distal hypospadias TIP repair reduces the morbidity associated with the stent and is a feasible option that carries acceptable immediate and delayed complication rates. Avoiding the stent eliminates stent-related bladder spasms, the need for other medications, and the short-term office visit for stent removal, therefore reducing parental anxiety, patient discomfort, and reducing cost.

Abstract
Our aim is to present patient outcomes for the TIPU method, currently mostly used for distal and sometimes proximal hypospadias treatment, and to identify predictive factors for the most commonly encountered complications of this surgery of urethrocutaneous fistula and urethral meatus stenosis. TIPU is a versatile, reliable, cosmetic and functionally successful surgical method mainly used for distal hypospadias patients but also in recent times for some proximal hypospadias patients. The main complications are urethrocutaneous fistula, urethral meatus stenosis, glans dehiscence and urethral meatus dehiscence. The pre-operative anatomic features of patients were assessed with the glans-meatus-shaft (GMS) scoring. Post-operative assessment of surgical outcomes was performed with the hypospadias objective scoring evaluation (HOSE). The mean total urethrocutaneous fistula and meatal stenosis development rates were 20 (12.3%) and 25 (15.4%). Both complications were found to be significantly high among hypospadias patients with narrow urethral plate, flat glandular groove and small glans (p < .001). Multivariate binary logistic regression analysis found urethral plate, glandular groove and glans shape were predictive factors for fistula and stenosis development.

Abstract
INTRODUCTION We present an alternative procedure for distal hypospadias consisting of urethral mobilization and glandular disassembly, named GUD-technique. MATERIAL AND METHODS After circumcision and exposure of distal dysplastic urethra, it is entirely mobilized from corpora and glans. Glans is deconstructed and incised in midline producing two wings almost not connected to glandular urethra at all. The urethra is then mobilized cranially and sutured to the tip of glans. Glans wings embrace the distal urethra producing a refurbished conical glans. DISCUSSION Koff et al. published a technique consisting of extensive urethral mobilization for hypospadias repair. Mitchell & Blagi and Perovic et al. reported on complete penile disassembly for epispadia repair as a way to complete release of the rotation of the penis and treat chordee bringing the urethra to a more functional location. We incorporated these two principles in GUD. The rationale is to avoid suture urethroplasty, simply repositioning the mobilized urethra distally and working aggressively on glans disassembly creating a more conical and cosmetic glans. The aggressive deconstruction of glans makes this technique unique. CONCLUSION We are convinced that this operation can be regarded as a genuine alternative to distal hypospadias after performing 100 cases in 3 years of experience.

Abstract
Hypospadias is one of the most common penile congenital anomalies, which often requires a surgical approach. After the hypospadias is repaired, urethral fistula can occur in around 20% of patients. In this study, we used platelet-rich plasma (PRP) to reduce the urethral fistula and other post-operative complications after hypospadias repair. Only patients with primary mid-penile hypospadias were included study. Patients with forms other than mid-penile hypospadias and cases with previous hypospadias surgery were excluded from the study. A total of 40 hypospadias patients were included in this study. These patients were divided into groups A and B with 20 patients in each group. Hypospadias repair was performed with the Snodgrass TIPU technique on both groups. PRP was used with group A, and PRP was not use with group B. These two groups were compared in terms of early and long-term post-operative complications. Both early and long-term post-operative UCF, urethral stenosis and post-operative infection rates were lower in the group using PRP, group A. PRP has the potential to prevent post-operative complications occurring after hypospadias repair, particularly post-operative infection.

Abstract
Introduction We present an alternative procedure for distal hypospadias consisting of urethral mobilization and partial glandar disassembly, namely GUD (glandar urethral disassembly) technique. Materials and Methods A subcoronal circumcision exposes distal dysplastic urethra. We incise the Buck´s fascia on both sides of urethra releasing it partially from the corpora. We keep a thin bridge of urethral plate to the glans and disassembly almost completely the glans from the corpora, except for the bridge. The glans is incised creating two wide wings that are extremely mobile. The urethra is mobilized, advanced and sutured to the tip of the glans. The glans wings embrace the distal urethra producing a conical glans. Discussion The concept of urethral mobilization has been reported and popularized by Koff in the literature to correct distal hypospadias. One of the limitations of this procedure is the risk of urethral retraction due to extensive proximal dissection. We got inspiration from Mitchell and Bagli’ s work of penile disassembly in epispadias to develop the GUD concept. We adopt minimal urethral mobilization mainly in glandar/proximal penile shaft and complete deconstruction of the glans, detaching the corpora from the glans and rotating the wide glans wings to embrace the urethra. Therefore we avoid suture urethroplasty and refurbish the glans to a better conical shape. Conclusion We are convinced that this operation can be regarded as a genuine alternative to distal hypospadias (coronal and subcoronal) but should not be addressed to midshaft forms.

Front Pediatr 2020; 8:579364. [PMID: 33363061 PMCID: PMC7756017 DOI: 10.3389/fped.2020.579364] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2020] [Accepted: 10/13/2020] [Indexed: 12/29/2022] Open
Abstract
Purpose: The aim of this study was to systematically review the literature on the complications and postoperative outcomes of children with non-proximal hypospadias. Methods: Electronic databases including PubMed, Embase, and Cochrane Library CENTRAL were searched systematically from January 1990 to June 2020 for the literature that reported the postoperative outcomes of patients with non-proximal hypospadias. Non-proximal hypospadias encompassed distal and mid-penile hypospadias. Results: We included 44 studies involving 10,666 subjects. Urethrocutaneous fistula (UCF) was the most common complication with an incidence of 4.0% (95% CI, 3.1-5.0%). Incidence of overall complications was 8.0% (95% CI, 6.3-9.8%). Meta-regression analysis revealed that length of urethral stent indwelling (coefficient 0.006; 95% CI, 0.000-0.011; p = 0.036) and penile dressing (coefficient 0.010; 95% CI, 0.000-0.021; p = 0.048) were two risk factors for UCF. Multivariate meta-regression analysis did not identify any independent risk factors for UCF. No differences were found between stent and stentless groups in non-proximal hypospadias regarding incidences of UCF (OR, 0.589; 95% CI, 0.267-1.297), meatal stenosis (OR, 0.880; 95% CI, 0.318-2.437), and overall complications (OR, 0.695; 95% CI, 0.403-1.199). No differences were found between foreskin preservation and circumcision in terms of complications either. Conclusions: UCF is the most common complication following hypospadias repair with an incidence of 4.0%. Independent risk factors for UCF were not identified in the current research. Distal hypospadias repair without stent indwelling is not likely to compromise the postoperative outcome. Further studies should be designed to explore the differences between different surgical approaches and the potential risk factors for complications following hypospadias repair.

Postoperative outcomes in distal hypospadias: a meta-analysis of the Mathieu and tubularized incised plate repair methods for development of urethrocutaneous fistula and urethral stricture. Pediatr Surg Int 2019; 35:1301-1308.

Abstract
PURPOSE To compare the two major complications, namely postoperative urethrocutaneous fistula and urethral stricture, between the Mathieu and tubularized incised plate (TIP) repair methods for distal hypospadias. METHODS In this meta-analysis, electronic databases were searched for comparative studies on the two techniques. The Oxford Centre for Evidence-based Medicine Levels of Evidence was used to evaluate the included studies. The main outcome measure was the frequency of postoperative fistula and urethral stricture. RevMan 5.3 was used for statistical analyses, with P < 0.05 indicating statistical significance. RESULTS A total of 17 studies, which included 1572 patients, met the inclusion criteria. The frequency of urethrocutaneous fistula did not differ between the Mathieu [115 (13%)] and TIP [90 (13%)] methods [odds ratio (OR) 1.1, 95% confidence intervals (CI) 0.6-1.9; P = 0.73)]. Urethral stricture was less frequent after the Mathieu [15 (2%)] method than after the TIP [37 (5%)] method (OR 0.5, 95% CI 0.3-0.8; P < 0.01), even after the subgroup analysis of eight randomized controlled trials was included. Overall, the quality of the included studies was determined to be satisfactory. The levels of evidence on which this review was based ranged from 1b to 2b using the CEBM Levels of Evidence. CONCLUSION Compared with TIP repair, Mathieu repair for hypospadias had a significantly lower risk for urethral stricture; however, the risk for urethrocutaneous fistula was similar.

Abstract
OBJECTIVE Maintaining a bloodless operative field is a crucial step in achieving success and reducing complications in hypospadias surgery. So, far, the most harmless and least damaging technique in terms of penile tissue oxygenation during hemostasis has not still been defined. We aimed to present our new technique of gas (oxygen) insufflation for better visualization of the operative field, and to compare this with the control group, where a wet sponge was used for hemostasis. MATERIAL AND METHODS A total of 28 patients with primary distal hypospadias who were treated with modified tubularized incised plate urethroplasty (TIPU) repair between March 2017 and October 2018 were evaluated prospectively. The patients were divided randomly into two groups. While only a wet sponge was used to clean hemorrhagic area in the control group (group I) (n=12), gas (oxygen) insufflation was used to visualize the operative field during the operation in the patient group (group II) (n=16). The patients' ages, operation time, follow-up durations, and postoperative complications were documented and statistically compared. RESULTS The mean ages and follow-up durations of both groups were found to be similar. The operation time was statistically shorter in group II than in group I (p=0.01). Eight patients (66.7%) in group I showed a complication, while 2 patients (12.5%) in group II showed a complication (p=0.005). CONCLUSION The gas (oxygen) insufflation technique provides good visualization during the dissection step of hypospadias surgery and results in better postoperative outcomes. Therefore, we think that this technique can be preferred as an alternative method for the visualization of the operative field in hypospadias surgery.

Abstract
Objective Hypospadias patients may present with the phenotype that features the migration of scrotum to distal penile shaft below a coronal/subcoronal meatus. Patients with this phenotype differ widely in the severity of the hypospadias and the complexity of the surgical repair. We aimed to investigate the operative findings and the outcomes of consecutive patients who presented with this phenotype. Methods We retrospectively reviewed the medical charts of 31 consecutive patients who underwent hypospadias repairs from January 2014 to May 2017, and the hypospadias was characterized by i) the external urethral meatus at coronal/subcoronal region, ii) scrotal skin encroaching distally resulting in fixation of penoscrotal angle at distal penile shaft, and iii) urethral plate below the glans on penile shaft invisible or barely visible. Results The median age at the time of surgery was 15.5 months (10–63). The division of corpus spongiosum was noted at distal penile shaft (n=2; 6.5%), mid-shaft (n=5; 16.1%) and proximal location (n=24; 77.4%). The median ventral curvature before degloving was 45 degrees (10–90). Twenty-eight and 3 patients underwent tubularized incised plate and 2-stage preputial flap repairs, respectively. Twenty-nine of 31 patients required cutback of the hypoplastic urethra. At the time of urethroplasty, 2 (6.5%), 7 (22.6%) and 22(70.9%) patients underwent distal, mid-shaft and proximal repairs, respectively. At a median follow-up of 30 months (14–50), 6 (19.4%) patients developed one or more complications (fistula=3; meatal stenosis=5). Conclusion Patients affected by this particular phenotype likely require non-distal hypospadias repair with possibly higher complication rate and should be treated by surgeons with expertise in complex hypospadias repair.

Abstract
BACKGROUND Children with hypospadias, being born with congenital abnormalities, having repeated genital examination, hospitalization, and undewent genital surgery, experienced psychological stress that may negatively affect their psychosocial life. Choosing the proper time of surgery as recommended is important, since it may have a positive impact on the psychosocial adaptation. AIM This study aims to find the risk factors causing psychosocial disorders in post-repair surgery on hypospadias children. METHODS This is a case control study, from 203 hypospadias patients underwent urethroplasty from 2009 to 2018. Subjets were screened for psychosocial disorders by Pediatric Symptoms Questionnaire 17 (PSC-17) questionnaire to find those with psychosocial disorders, score 15 or more (case group) and those without psychosocial disorders (control group), score 0-14. We traced back the data retrospectively from both group (history of utrethrocutaneous fistula and meatal stenosis, age upon urethroplasty) and collecting new ones (cosmetic outcome, emotional stress after genital examination, and the existence of PTSD). Fisher's exact test was performed to see the Odds ratio (OR) for each variable. RESULTS Some children with hypospadias show impaired on psychocosial. Functional and cosmetic outcome not significantly different as potensial risk factor psychosocial disorders, genital examination doesn't trigger psychological stress and also none children show PTSD symtomp after surgery. Comparison time of age urethroplasty did not differ significantly between two group. CONCLUSIONS Twenty-nine children post urthroplasty show psychosocial disorders. Functional and cosmetic urethroplasty outcomes, emotional stress after genital examination, post-traumatic stress disorder were not risk factors of pshycosocial disorder of hypospadias patients. Ages at time of surgery did not differ significantly between two group and this is contradict to the previous recommendations.

Abstract
OBJECTIVE To detect whether grafting the incised plate during Snodgrass repair would improve outcome. MATERIALS AND METHODS Sixty patients with primary distal hypospadias were included. Patients were equally randomized using closed envelop method to either Snodgrass or grafted tubularized incised plate repair (GTIP). All operations were performed by a single surgeon. All intaroperative data were recorded. All patients were followed up for 1 year. Success was defined as slit shaped meatus at the tip of the glans with no stenosis, fistula or diverticulum. RESULTS All 60 patients were evaluated at 1 year of follow-up. Mean age at surgery was 40±15months. Both groups were comparable as regard to patients' age, meatus location, length and width and depth of urethral plate and glans width. Success was documented in 29/30 patients (96.7%) in the Snodgrass group. The only complication was meatal stenosis in one patient, whereas success was documented in 28/30 patients (93.3%) in the GTIP group. The two failures were secondary to partial glans dehiscence. Success rate was not statistically different. Flow rate data at 1 year showed insignificant difference between both groups as regards Q-max and voiding time. The only statistically significant difference between both groups was a longer operative time 106±12min in the GTIP group compared to only 77±9 for the Snodgrass group (p = 0.005). CONCLUSIONS Snodgrass and GTIP techniques for primary distal hypospadias repair have similar outcome. With a significantly shorter operative time, Snodgrass repair remains the first choice for primary distal hypospadias repair. TYPE OF THE STUDY Prospective randomized study.

Abstract
INTRODUCTION Two reports have found that urethral plate (UP) widths <8 mm before tubularized incised plate (TIP) incision increased urethroplasty complications. The present study measured pre-incision UP width in consecutive boys undergoing TIP to determine if it affected outcomes. METHODS The present study followed the method previously used by Holland and Smith, and Sarhan et al. to measure UP width before creating glans wings or performing midline plate incision in consecutive patients with primary hypospadias and ventral curvature <30°, who all underwent TIP repair (Summary Fig.). Glans width at its widest point was also measured. Multiple logistic regression assessed urethroplasty complications (fistula, glans dehiscence, meatal stenosis/urethral stricture, diverticulum) based on pre-incision UP width, glans width, patient age, and meatal location. RESULTS The UP widths were determined in 224 consecutive primary TIP repairs during 2012-2015: 200 distal, 11 midshaft, and 13 proximal. The UP width was <8 mm in 192/224 (86%) patients. Mean pre-incision width was 6.1 mm (SD 1.5, range 2-11), without difference in UP widths according to meatal location (P = 0.06). Mean post-incision UP width was 12 mm (SD 2.2, range 10-16). Mean change in width after incision (delta/original UP width) was 116% (SD 63, range 20-250). There was follow-up in 186 patients for a mean of 6 months. Urethroplasty complications (five fistulas, six glans dehiscence) were diagnosed in 11 (6%): 9/165 distal, 1/9 midshaft, and 1/12 proximal repairs. There was no difference in those <8 vs ≥8 mm (11/160 vs 0/26, P = 0.17). Similarly, UP width was not different between patients with and without urethroplasty complications. Multiple logistic regression in these 186 patients - including meatal location, UP width, glans width, and age - found only glans width <14 mm was associated with increased odds of urethroplasty complications (OR 19.2, 95% CI 3.5-106, AUC = 0.799). DISCUSSION The data show that pre-incision UP width is not an independent risk factor for urethroplasty complications. However, it is possible that technical factors, such as how deeply the dorsal incision is made or size of the urethral stent, might contribute to this finding by other authors. After watching the TIP repair, Smith stated that the plate incision was deeper than he made. Sarhan et al. reported a mean change of 57% in UP width after incision, whereas the present one was double at 116% (i.e. from 6 mm pre-incision to 12 mm post incision), and they used an 8-Fr catheter. While they stated that they incised the plate deeply, the lower percentage increase in width suggests that it was not as deep as was recommended. CONCLUSIONS The UP width before incision did not increase urethroplasty complications. Surgeons do not need to measure or categorize the UP to determine suitability for TIP repair, as long as the plate incision is made deeply to the corpora.

Abstract
INTRODUCTION Hypospadias surgery has progressed steadily over recent years. There remains considerable variation in the operative management of boys with hypospadias in the UK, and it is therefore difficult to identify acceptable standards with regards to reoperation rates. OBJECTIVE To determine the frequency of reoperations and complications from all centres performing hypospadias surgery in England and to identify variables that influence outcome. METHODS All children undergoing NHS hypospadias surgery in England between 1999 and 2009 were identified using the Hospital Episode Statistics database. Patient demographics, centre type, and associated diagnostic (ICD-10) and treatment codes (OPCS4.6) were collected for both primary repairs and postoperative complications. Centres were classed as high volume if they performed an average of 20 or more operations a year. Operative complications were split into revisions (repeat repairs), repairs of urethral fistulae, repairs of meatal stenosis, or urethral stricture repairs. Statistical analysis included logistic regression, Spearman's correlation, and Mann-Whitney U for non-parametric data, with p < 0.05 taken as significant. Data are presented as median (interquartile range) unless otherwise stated. RESULTS children underwent a total of 23,962 operations at 75 centres in England during the study period. The median age at primary repair was 21 (15-38) months. The overall complication rate was 18.1%. The median complication rate for individual centres was 20.0% (13.9-27.4%) overall; 10.8% (4.7-15.9%) for revision procedures, 8.1% (5.5-11.7%) for urethral fistulae, 2.3% (1.1-3.7%) for meatal stenosis repairs, and 1.8% (0-2.8%) for urethral strictures. High volume centres had significantly lower complication rates than low volume centres (17.5% vs. 25%, p = 0.01) (Figure), and this was proven to be an independent predictor of outcomes (p = 0.01). Staged repairs were associated with more complications (p < 0.001); however, patient age and centre type were not. Median time to repair of complication was 13 (8-22) months. DISCUSSION This national population-based study used hospital episode statistics data. While accuracy is high and it has been validated for use in research, it has intrinsic limitations which affect our study. We are unable to fully account for the severity of hypospadias or the number of operating surgeons within institutions. CONCLUSIONS This study has found a clear relationship between caseload volume and complications following hypospadias surgery. Furthermore, there is significant variability between centres in terms of their surgical outcomes. Taken together these results suggest that surgeons, particularly those in centres with small caseloads should assess their results against such benchmarks when evaluating the service they provide.

Abstract
Paediatric urological surgery is often required for managing congenital and acquired disorders of the genitourinary system. In this Series paper, we highlight advances in the surgical management of six paediatric urological disorders. The management of vesicoureteral reflux is evolving, with advocacy ranging from a less interventional assessment and antimicrobial prophylaxis to surgery including endoscopic injection of a bulking agent and minimally invasive ureteric reimplantation. Evidence supports early orchidopexy to improve fertility and reduce malignancy in boys with undescended testes. A variety of surgical techniques have been developed for hypospadias, with excellent outcomes for distal but not proximal hypospadias. Pelvi-ureteric junction obstruction is mostly detected prenatally; indications for surgery have been refined with evidence, and minimally invasive pyeloplasty is now standard. The outlook for patients with neurogenic bladder has been transformed by a combination of clean intermittent catheterisation, algorithms of diagnostic investigations, and innovative medical and surgical therapies. Posterior urethral valves are associated with considerable mortality; fetal diagnosis allows stratification of candidates for intervention, but ongoing bladder dysfunction in patients after valve ablation remains a cause of long-term morbidity.

Abstract
Objectives. Hypospadias is a congenital affliction in which the urethral meatus is located on the underside of the penis. These cases are usually treated during childhood by pediatric surgeons, but more complex forms tend to reoccur, and after several failed attempts end up as hypospadias cripple in the care of urologists at an adult age. The aim of this paper is to present the management of a complex case of hypospadias cripple associated with penile curvature (chordee). Materials and Methods. A 24 year old patient presented in our clinic with hypospadias cripple and ventral penile curvature. At the physical examination we found a penoscrotal urethral meatus, heavy scaring of the distal ventral penis and a ventral chordee of approximately 90 degrees in erect state. A two stage “Bracka” repair technique with buccal mucosa graft was chosen. The first stage of the surgery consisted of removing the scarred and defective distal urethral plate and the fibrotic tissue responsible for the penile curvature, preparing the corpora cavernosa for the graft, clefting the glans, harvesting two buccal mucosa grafts from both inner cheeks, and finally quilting the grafts on the defect. The second stage of the repair was performed after a period of about six months, and consisted in the tubularization of the matured graft and glans plasty. Results and Conclusions. No immediate or late complications occurred after any of the two stages of the surgery; no significant ventral chordee was observed and no urethral fistula occurred till the one year follow-up. A two stage “Bracka” repair technique is best suited for treating these patients, correcting ventral chordee in the first session.

Abstract
INTRODUCTION Recent reports have suggested that caudal anesthesia may be associated with an increased risk of postoperative surgical complications. We examined our experience with caudal anesthesia in hypospadias repair to evaluate for increased risk of urethrocutaneous fistula or glanular dehiscence. METHODS All hypospadias repairs performed by a single surgeon in 2001-2014 were reviewed. Staged or revision surgeries were excluded. Patient age, weight, hypospadias severity, surgery duration, month and year of surgery, caudal anesthesia use, and postoperative complications were recorded. Bivariate and multivariate statistical analyses were performed. RESULTS We identified 395 single-stage primary hypospadias repairs. Mean age was 15.6 months; 326 patients had distal (83%) and 69 had proximal (17%) hypospadias. Caudal anesthetics were used in 230 (58%) cases; 165 patients (42%) underwent local penile block at the discretion of the surgeon and/or anesthesiologist. Complications of urethrocutaneous fistula or glanular deshiscence occurred in 22 patients (5.6%) and were associated with caudal anesthetic use (OR 16.5, 95% CI 2.2-123.8, P = 0.007), proximal hypospadias (OR 8.2, 95% CI 3.3-20.0, P < 0.001), increased surgical duration (OR 1.01, 95% CI 1.01-1.02, P < 0.001), and earlier year of practice (OR 3.0, 95% CI 1.2-7.9, P = 0.03 for trend). After adjusting for confounding variables via multivariable logistic regression, both caudal anesthetic use (OR 13.4, 95% CI 1.8-101.8, P = 0.01) and proximal hypospadias (OR 6.8, 95% CI 2.7-16.9, P < 0.001) remained highly associated with postoperative complications. CONCLUSIONS In our experience, caudal anesthesia was associated with an over 13-fold increase in the odds of developing postoperative surgical complications in boys undergoing hypospadias repair even after adjusting for urethral meatus location. Until further investigation occurs, clinicians should carefully consider the use of caudal anesthesia for children undergoing hypospadias repair.

[PMID: 28043766 DOI: 10.1016/j.jpurol.2016.11.012] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2016] [Accepted: 11/14/2016] [Indexed: 11/18/2022]
Abstract
PURPOSE The primary aim of this report was to compare urethroplasty complications for primary distal and proximal repairs with those after 1, 2, 3, and 4 or more re-operations. METHODS Prospectively collected data on consecutive hypospadias repairs (tubularized incised plate (TIP), inlay, two-stage graft) from 2000 to 2015 were reviewed. Isolated fistula closures were excluded. Extracted information included patient age, meatal location, repair type, primary vs. re-operative surgery, number of prior operations, any testosterone use, glans width, and urethroplasty complications. Pre-operative testosterone stimulation was used during the study period until 2012. Initially, it was given for a subjectively small-appearing glans, but from 2008 to 2012 use was determined by glans width <14 mm. Patients initially managed elsewhere were queried for any testosterone treatment. The number of prior operations was determined by patient history and confirmed by review of records. Calibrations, dilations, cystoscopies, and/or isolated skin revisions were not considered as prior urethroplasty operations. Multiple logistic regression was performed for all patients, and for the subset of patients undergoing re-operation, using stepwise regression for the following potential risk factors: meatal location (distal vs. midshaft/proximal), number of prior surgeries (0, 1, 2, 3, ≥4), pre-operative testosterone use (yes/no), small glans (<14 vs. ≥14), surgery type (TIP, inlay and two-stage graft), and age (continuous in months), with P-values <0.05 considered statistically significant. RESULTS In contrast to the 135/1085 (12%) complication rate in patients undergoing primary distal and proximal TIP repair, re-operative urethroplasty complications occurred in 61/191 (32%) TIP, 16/46 (35%) inlay, and 49/124 (40%) two-stage repairs, P<0.0001. Data regarding testosterone use was available for 1490 (96%) patients. A total of 139 received therapy, of which 65 (46%) had urethroplasty complications vs. 229 of 1351 (16%) without treatment, P = 0.0001. Logistic regression in 1536 patients demonstrated that each prior surgery increased the odds of subsequent urethroplasty complications 1.5-fold (OR 1.51, 95% CI 1.25-1.83), along with small glans <14 mm (OR 2.40, 95% CI 1.48-3.87), mid/proximal meatal location (OR 2.54, 95% CI 1.65-3.92), and use of pre-operative testosterone (OR 2.57, 95% CI 1.53-4.31); age and surgery type did not increase odds (AUC = 0.739). DISCUSSION Urethroplasty complications doubled in people undergoing a second hypospadias urethroplasty compared with those undergoing primary repair. This risk increased to 40% with three or more re-operations. Logistic regression demonstrates that each surgery increases the odds for additional complications 1.5-fold. Mid/proximal meatal location, small glans <14 mm, and use of pre-operative testosterone also significantly increase odds for complications. These observations support the theory that previously operated tissues have less robust vascularity than assumed in a primary repair, and suggest additional adjunctive therapies are needed to improve wound healing in re-operations. The finding that even a single re-operative urethroplasty has twice the risk for additional complications vs. a primary repair emphasizes the need for hypospadias surgeons to 'get it right the first time'. The fact that 40% of the re-operative urethroplasties in this series followed distal repairs emphasizes that there is no 'minor' hypospadias. CONCLUSIONS A single re-operative hypospadias urethroplasty has twice the risk for additional complications vs. the primary repair, which increases to 40% with three or more re-operations. These results support a theory that vascularity of penile tissues decreases with successive operations, and suggest the need for treatments to improve vascularity. The higher risk for complications during re-operative urethroplasties also emphasizes the need to get the initial repair correct.

Abstract
OBJECTIVE Our objective was to evaluate quality of conduct and reporting of published systematic reviews and meta-analyses in paediatric surgery. We also aimed to identify characteristics predictive of review quality. BACKGROUND Systematic reviews summarise evidence by combining sources, but are potentially prone to bias. To counter this, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was published to aid in reporting. Similarly, the Assessing the Methodological Quality of Systematic Reviews (AMSTAR) measurement tool was designed to appraise methodology. The paediatric surgical literature has seen an increasing number of reviews over the past decade, but quality has not been evaluated. METHODS Adhering to PRISMA guidelines, we performed a systematic review with a priori design to identify systematic reviews and meta-analyses of interventions in paediatric surgery. From 01/2010 to 06/2016, we searched: MEDLINE, EMBASE, Cochrane, Centre for Reviews and Dissemination, Web of Science, Google Scholar, reference lists and journals. Two reviewers independently selected studies and extracted data. We assessed conduct and reporting using AMSTAR and PRISMA. Scores were calculated as the sum of reported items. We also extracted author, journal and article characteristics, and used them in exploratory analysis to determine which variables predict quality. RESULTS 112 articles fulfilled eligibility criteria (53 systematic reviews; 59 meta-analyses). Overall, 68% AMSTAR and 56.8% PRISMA items were reported adequately. Poorest scores were identified with regards a priori design, inclusion of structured summaries, including the grey literature, citing excluded articles and evaluating bias. 13 reviews were pre-registered and 6 in PRISMA-endorsing journals. The following predicted quality in univariate analysis:, word count, Cochrane review, journal h-index, impact factor, journal endorses PRISMA, PRISMA adherence suggested in author guidance, article mentions PRISMA, review includes comparison of interventions and review registration. The latter three variables were significant in multivariate regression. CONCLUSIONS There are gaps in the conduct and reporting of systematic reviews in paediatric surgery. More endorsement by journals of the PRISMA guideline may improve review quality, and the dissemination of reliable evidence to paediatric clinicians.

Abstract
This review summarizes data regarding commonly used surgical techniques to repair distal and proximal hypospadias. We review evidence concerning indications for various procedures used in primary hypospadias repair, and their complications, urinary function and esthetic results. Available evidence suggests TIP is preferable to Mathieu for distal hypospadias correction. Current data do not identify a clear preference between TIP and onlay flap for proximal repair when there is ventral curvature <30°, or between various flap and graft options when curvature is >31°. A review of objective data helps clarify decision-making for distal hypospadias repair. Additional objective evidence is needed to identify preferred options for proximal hypospadias repair. Measuring glansplasty dimensions (meatal size and distance from meatus to corona) may improve urinary function assessments, and provide additional objective data for decision-making between various surgical techniques.

Abstract
PURPOSE To investigate and compare the outcomes after tubularized incised plate (TIP) urethroplasty in mid-shaft and proximal hypospadias using a standard and a modified technique. METHODS We conducted a retrospective study in 104 consecutive children who underwent mid-shaft or proximal TIP repairs from Jan 2007 to Sept 2015. Patients in Cohort One had dorsal dartos (DD) neourethral coverage while patients in Cohort Two had either de-epithelialized split preputial (DESP) or tunica vaginalis (TV) flap coverage. TV flap was used only when DESP flap was not sufficient to cover the neourethra. RESULTS There were 52 patients each in Cohort One (DD, n = 52) and Cohort Two (DESP, n = 38; TV, n = 14) with no difference in ratio of mid-shaft/proximal between the two cohorts. At a median follow-up of 28 months, 36 patients (34.6 %) developed 47 complications including fistula (n = 19; 18.3 %) and neourethral dehiscence (n = 4; 3.8 %). Cohort One patients had significantly more fistula (28.8 vs 7.7 %; p = 0.005) and neourethral dehiscence (7.7 vs 0 %; p = 0.04) than Cohort Two. There was no difference between the two cohorts in the complication rates of meatal stenosis, recurrent ventral curvature and neourethral stricture. CONCLUSIONS Both DESP and TV flap appear to be superior to DD in preventing fistula and neourethral dehiscence in non-distal TIP repairs.

Abstract
BACKGROUND Over the past two decades, Snodgrass tubularized incised plate (TIP) urethroplasty has become one of the dominant surgical techniques with wide applications and excellent cosmetic results. However, TIP has many limitations. We performed a retrospective study at our department and assessed the outcome of the inlay internal preputial graft for extending the applications of TIP. METHODS Between January 2009 and December 2013, we performed a retrospective study consisting of approximately 508 primary distal and moderate cases. Patients with primary distal hypospadias who had mild or no chordee and good penile development were divided into the following 3 groups based on their procedures: (1) classic TIP hypospadias repair group (n = 198); (2) inlay buccal mucosa graft group (n = 150); and (3) inlay internal preputial graft group (n = 160). The median age was 1.6 years (range 1-4 years). Our data were analyzed statistically by the Chi square test with P < 0.05 indicating significant differences. RESULTS The mean follow-up period was 18 months (range 6‒24 months). In the classic TIP group, the incidence of urinary fistula and meatal stenosis were both 3.0 % (6/198); in the inlay buccal mucosal graft group, the incidence of urinary fistula was 3.3 % (5/150), and the incidence of stenosis was 2.7 % (4/150); and in the inlay internal preputial graft group, the incidence of urinary fistula was 3.1 % (5/160), and the incidence of meatal stenosis was 4.4 % (7/160). The success rates of each group were as follows: the classic TIP group has a success rate of 93.9 % (186/198); the inlay buccal mucosa graft group had a success rate of 94.0 % (141/150); and the inlay internal preputial graft group had a success rate of 92.5 % (148/160). There were no statistically significant differences between the 3 groups with respect to complication rates. CONCLUSIONS As the inner foreskin Snodgraft does not appear to be worse than the buccal mucosa graft, it is a good method for hypospadias repair, and this method is not inferior to TIP.

Results of distal hypospadias repair after pediatric urology fellowship training: A comparison of junior surgeons with their mentor. J Pediatr Urol 2016; 12:162.e1-4.

Abstract
BACKGROUND Teaching and learning hypospadias repair is a major component of pediatric urology fellowship training. Educators must transfer skills to fellows, without increasing patient complications. Nevertheless, few studies report results of surgeons during their first years of independent practice. PURPOSE To review outcomes of distal hypospadias repairs performed during the same 2-year period by consecutive, recently matriculated, surgeons in independent practice, and to compare them to results by their mentor (with >20 years of experience). MATERIALS Exposure to hypospadias surgery during fellowship was determined from case logs of five consecutive fellows completing training from 2007-2011. TIP was the only technique used to repair distal hypospadias. No fellow operated independently or performed complete repairs under supervision. Instead, the first 3 months were spent assisting their mentor, observing surgical methodology and decision-making. Then, each performed selected portions under direct supervision, including: degloving, penile straightening, developing glans wings, incising and tubularizing the urethral plate, creating a barrier layer, sewing the glansplasty, and skin closure. Overall fellow participation in each case was <50%. In 2011-2012, urethroplasty complications (fistula, glans dehiscence, meatal stenosis, urethral stricture, diverticulum) were recorded for consecutive patients undergoing primary distal repair by these recent graduates in their independent practices. The fellow graduating in 2011 provided 1 year of data. All patients undergoing repair during the study period were included in the analysis, except those lost to follow-up after catheter removal. Composite urethroplasty complications were compared between junior surgeons, and between junior surgeons and their mentor, with Fisher's exact contingency test. RESULTS Training logs indicated fellow participation ranged from 76-134 hypospadias repairs, including distal, proximal and reoperative surgeries. Post-graduation case volumes ranged from 25-68 by junior surgeons versus 136 by the mentor. With similar mean follow-up, urethroplasty complication rates were statistically the same between the former fellows, and between them versus the mentor, ranging from 5-13%. Nearly all were fistulas or glans dehiscence. Junior surgeons reported they performed TIP as learned during fellowship, with one exception who used 7-0 polydioxanone rather than polyglactin for urethroplasty. DISCUSSION This is the first study directly comparing hypospadias surgical outcomes by recently graduated fellows in independent practice with those of their mentor. We found junior surgeons achieved similar results for distal TIP hypospadias repair. Although their participation during training largely comprised observation and surgical assistance, with discrete performance of key steps, skills sufficient to duplicate the mentor's results were transferred. These data suggest there should be no learning curve for distal hypospadias after training. This report raises several considerations for surgical educators. First, mentors should review their own results, to be certain that they are correctly performing and teaching procedures. Second, programs need to determine key steps for procedures they teach, and then emphasize their optimal performance. Finally, mentors should expect former fellows to report back their initial results of hypospadias repair to be certain lessons taught were learned. Otherwise, preventable complications resulting from technical errors will be multiplied in the children operated by their trainees as they enter independent practice.

Abstract
OBJECTIVE We review development and evolution of TIP hypospadias repair, including technical changes made to improve its results. We also discuss general risk factors for hypospadias surgical complications. METHODS We describe use of a database with prospective data entry to first identify our most common complications and their frequency, and then to monitor results of technical modifications made to reduce their occurrence. Multiple logistic regression of various factors recorded in the database was done to identify those predicting increased risk for urethroplasty complications. RESULTS Fistula and glans dehiscence are the two most common complications we encountered after TIP repair. Changes in urethral plate tubularization and barrier layers covering the neourethra resulted in a significant reduction in fistulas after proximal TIP. Changes in glansplasty sutures and use of preoperative testosterone to increase glans size did not reduce likelihood for dehiscence, whereas increasing the extent of glans wings dissection did. Logistic regression analysis confirmed proximal meatal location and reoperation predicted increased complications, but also identified glans width ≤ 14 mm as an independent risk factor for hypospadias urethroplasty complications. CONCLUSIONS Systematic, prospective data collection facilitated identification of complications and their risk factors, and provided a means to assess results of modifications made to address them. Limiting the algorithm used for hypospadias repair increases expertise in those techniques used. Reported low surgical volumes for proximal hypospadias repair suggest subspecialization of these cases be carried out so that designated surgeons can achieve sufficient volume to analyze their results and make improvements.
