Abstract
INTRODUCTION Hypospadias is one of the most common congenital anomalies in men. Outpatient surgery has been proposed but is not widespread. The aim of this study was to evaluate our experience of outpatient surgery for penile hypospadias repair and to specify the constraints for a result similar to a conventional inpatient procedure. PATIENTS AND METHODS Observational, retrospective and single-center study, including all the patients operated on hypospadias for the first time by one of the 3 senior surgeons, between January 2011 and March 2018. Peno-scrotal and perineal hypospadias were excluded because systematically hospitalized. RESULTS One hundred sixty-six patients were included. 67 patients (40,4%) were treated on an outpatient basis. The mean age at the time of procedure was 15.6 (6-51) months. Forms with curvature were almost exclusively hospitalized (1 vs. 25, P<0.001). There was no significant difference for anterior penile forms (60 vs. 81, P=0.06). Middle and posterior hypospadias were more often hospitalized, although outpatient experience exists. There were no more complications in the outpatient group. CONCLUSION Outpatient hypospadias surgery seems to be achievable in most of the cases, provided that medical care is standardized and multidisciplinary, the staff is trained and involved and a specific organization is put in place in the department. Evaluation of the socio-family environment is therefore fundamental. LEVEL OF EVIDENCE: 4

Abstract
INTRODUCTION Neourethral covering is an essential technique for preventing complications such as fistula and glans dehiscence in hypospadias repairs. The spongioplasty has been reported for neourethral coverage about 20 years ago. However, reports of the outcome are limited. OBJECTIVE This study aimed to retrospectively evaluate the short-term outcome of spongioplasty with Buck's fascia covering dorsal inlay graft urethroplasty (DIGU). METHODS From December 2019 to December 2020, 50 patients with primary hypospadias (median age at surgery, 37 months; range, 10 months-12 years) were treated by a single pediatric urologist. The patients underwent spongioplasty with Buck's fascia covering dorsal inlay graft urethroplasty in single stage. The penile length, glans width, urethral plate width and length, and the location of the meatus of the patients were recorded preoperatively. The patients were followed up,complications noted, and postoperative uroflowmetries at the one-year follow-up time were evaluated. RESULTS The average width of glans was 12.92 ± 1.86 mm. A minor penile curvature was observed in all patients (≤30°). The patients were followed up for 12-24 months, and 47 patients (94%) were free from complications. A neourethra formed with a slit-like meatus at the tip of the glans, and the urinary stream was straight. Three patients had coronal fistulae (3/50) and no glans dehiscence, and the mean ± SD Qmax of postoperative uroflowmetry was 8.13 ± 3.8 ml/s. DISCUSSION This study estimated the short-term outcome of the DIGU covered using spongioplasty with Buck's fascia as the second layer in patients diagnosed with primary hypospadias with a relatively small glans (average width <14 mm). However, only a few reports emphasize spongioplasty with Buck's fascia as the second layer and the DIGU procedure performed on a relatively small glans. The major limitations of this study were its short follow-up time and the retrospective data collection. CONCLUSIONS Dorsal inlay graft urethroplasty combined with spongioplasty with Buck's fascia as coverage is an effective procedure. In our study, this combination had good short-term outcomes for primary hypospadias repair.

Abstract
Objective To assess the outcome of a free preputial tube graft coupled with urethral plate urethroplasty combined with a Buck's fascia integral covering (BFIC) for the single-stage repair of severe hypospadias in children. Materials and methods A retrospective study was performed on 40 children with hypospadias who were treated in our hospital from December 2017 to February 2022. The inclusion criteria were as follows: (1) the patient had proximal hypospadias, or penile curvature over 30° after degloving the penis; and (2) the patient underwent surgery for hypospadias for the first time. A free preputial tube graft coupled with urethral plate urethroplasty combined with a Buck's fascia integral covering was performed, and all patients were followed up for more than 6 months. Results After degloving the foreskin, the urethral orifice was retracted to the perineum and scrotum in 20 cases, penoscrotal in 8 cases, and penile in 12 cases. Single-stage repair was achieved without complications in 34 (85%) patients. The remaining six patients experienced postoperative complications: urethrocutaneous fistula occurred in five cases and glans dehiscence with urethrocutaneous fistula in one case. No urethral diverticulum occurred in any case. A neomeatus with a vertically oriented slit-like appearance was achieved at the tip of the glans in all cases, with one exception. Conclusion The single-stage operation with a free preputial tube graft coupled with urethral plate urethroplasty combined with a Buck's fascia integral covering in the treatment of severe hypospadias achieves favorable functional and cosmetic outcomes.

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
BACKGROUND Glanular dehiscence (GD) is one of the main complications after hypospadias surgery. There is a limited number of publications regarding GD in the literature. OBJECTIVE The aim of this work is to reveal the factors that affect GD after a literature review. EVIDENCE ACQUISITION A literature search for relevant articles was performed in database using the search term glans dehiscence without setting date range limit or any other limits. All articles related to GD after hypospadias surgery were included in this study. After collecting the information from full text articles, 71 articles were included in this systematic review. In these studies, localization of hypospadic meatus, type of surgery, and other clinical data which were thought to behave as risk factors for GD were obtained. Chi-Square test was used to evaluate the differences between the parameters, where p < 0.05 was taken as statistically significant. RESULTS After evaluating the 71 articles that met the inclusion criteria, 309 cases (3.48%) of GD after 8858 hypospadias repairs were obtained in this review. GD rates were found significantly high for proximal hypospadias (5%), two-stage hypospadia repairs (5%) and re-do hypospadias repair (8.75%) (p = 0.002, 0.022, and 0.004, respectively). Glans width <14 mm, urethral plate (UP) width <7 mm, hypospadias surgeries performed before 6 months of age and after puberty, and caudal block anesthesia increased the rate of GD. CONCLUSIONS The rate of GD increases after proximal, cripple and staged hypospadias surgeries, a glans width <15 mm and UP width <8 mm, postpubertal surgeries, and caudal anesthesia use during surgery.

Abstract
INTRODUCTION Fistula following hypospadias repair remains a bane of the hypospadiologist resulting in the evolution of various techniques. Despite all these, the incidence of postoperative fistula varies from 10 to 30% and it increases with the severity of the hypospadias. Hence, a study was conducted to evaluate the efficacy of tunica vaginalis flap in preventing fistula formation following severe hypospadias repair. MATERIALS AND METHODS An observational study was carried out in a tertiary center between 2008 and 2017. The study included children with severe hypospadias (Proximal penile, Penoscrotal, scrotal, and Perineal). In all the patients, a Tunica-Vaginalis flap was used to buttress the urethroplasty. All the patients were followed up for at least a year after the completion of treatment. RESULTS A total of 210 patients were included in the study. Bracka's two-stage repair was performed in 180 patients who had either Penoscrotal hypospadias or a meatus even more proximal. The rest 30 patients with proximal penile hypospadias underwent a single-stage Snodgrass repair. Four (2%) patients developed a fistula, all following two-stage repairs, and half of them required surgical repair. Two (1%) patients had a partial breakdown of repair and underwent a residual repair after six months. CONCLUSION The Tunica-Vaginalis flap is an excellent buttress in severe hypospadias repair. It is readily available, easy to harvest, with its good vascularity helps to significantly reduce the incidence of postoperative fistula.

Abstract
Abstract
Background
Hypospadias surgery is technically demanding and is often encountered with complications like fistula and glanular dehiscence. To prevent these complications we have instituted Buck’s fascia repair (BFR) with wingless glanuloplasty (WLP) in the cases of distal penile hypospadias (DPH) deemed to be suitable for TIP repair. The aim of this prospective study was to assess the outcome of Buck’s fascia repair (BFR) with minimal wingless glanuloplasty (WGP).
Methods
This prospective study included 50 patients with coronal, subcoronal and midpenile hypospadias who received a tubularization of incised plate (TIP) repair. The exclusion criteria were glanular hypospadias, Thiersch Duplay repair, proximal penile hypospadias, previous penile surgeries, uncorrectable chordee, glans size < 14 mm, flat glanular groove and preoperative testosterone therapy.
Results
Over a period of 3 years, 50 patients with mean age of 3.5 ± 0.8 years were recruited for the study. Meatal position was coronal, subcoronal and midpenile in 6, 24 and 20 patients, respectively. Fistula occurred in one patient (2%) and meatal stenosis in one. Straining on micturition was noted in two patients that needed dilatation in postoperative period. None of the patients had glanular dehiscence. Surgeon acceptability of the procedure was good. Cosmetic results were also fair.
Conclusion
Buck’s fascia repair with Wingless glanuloplasty is a good repair for the distal penile hypospadias. It is effective and is associated with low fistula rates and glanular dehiscence. It is technically simple procedure involving minimal dissection. However, caution should be observed in midpenile hypospadias to avoid tight repair in subcoronal region.

Abstract
We aim to design a new glanuloplasty procedure combined with spongiosum to reduce the incidence of glans dehiscence and coronal fistula after proximal hypospadias repair. Patients who underwent urethroplasty by dorsal preputial island flap for proximal hypospadias between January 2014 and December 2016 were reviewed in this retrospective cohort study. Those who underwent spongiosum-combined glanuloplasty comprised the new-maneuver group, whereas those who underwent conventional glanuloplasty comprised the control group. The incidence of complications was then compared. In the new-maneuver group, dysplastic corpus spongiosum alongside lateral Buck's fascia (0.3-0.4 cm wide) on both sides of the urethral plate was separated from the proximal normal spongy tissue, joining into the glans wings to increase tissue volume and covering the neourethra in the glans penis. In the control group, the neourethra was covered with superficial fascia under the coronal sulcus. As a result, the new-maneuver and control groups comprised 47 and 28 patients, respectively. In the new-maneuver group, no glans dehiscence was detected; however, two (4.3%) patients had coronal fistula, two (4.3%) had urethral stricture, and four (8.5%) had diverticulum. In the control group, two (7.1%) patients had glans dehiscence, eight (28.6%) had coronal fistula, four (14.3%) had urethral stricture, one (3.6%) had diverticulum, and one (3.6%) had penile curvature recurrence. The new-maneuver group had less incidences of coronal fistula (P < 0.001), glans dehiscence (P = 0.033), and urethral stricture (P = 0.008) but had a higher incidence of diverticulum than the control group (P = 0.040). It clearly demonstrates that spongiosum-combined glanuloplasty can significantly reduce the incidences of coronal fistula and glans dehisce.

Abstract
Objectives: The objective of the study is to investigate the feasibility and efficacy of urethroplasty with a Buck's fascia integral-covering technique (BFIC) to wrap and restore the normal anatomical structure of the penis in one-stage hypospadias surgery. Methods: One-stage surgeries for hypospadias management were performed using BFIC from January 2016 to September 2020 at four high-volume medical centers in China. The technique integrates Buck's fascia with glans wings to mobilize and wrap the urethra and restore penile anatomical relationships. The clinical data, postoperative follow-up data, and complications were recorded, and the results were analyzed. Results: A total of 1,386 patients were included in the study: 1,260 cases of primary hypospadias and 126 cases of re-operations; distal in 382 cases (27.6%), mid-shaft in 639 (46.1%), proximal in 365 (26.3%); tubularized incised plate (TIP) in 748 cases, inlay-graft in 124, onlay-graft in 49, Mathieu in 28, free-tube graft urethroplasty in 406, and 31 of hybrid procedures. One thousand one hundred forty-two patients (82.4%) were found to have penile curvature (>10°) after artificial erection and all corrected by dorsal plication/s or transection of the urethra plate (UP) simultaneously. The median followed-up time was 27 months (6-62). A total of 143 (10.3%) complications were recorded: 114 (9.0%) in the primary operations and 29 (23%) in the re-operations, 15 (3.9%) in distal hypospadias, 61 (9.5%) in mid-shaft, and 67 (18.4%) in proximal. The complication rate in UP preservation and transection was 10.1 and 10.8%, respectively. Of all case complications, there were 73 (5.2%) of fistula, 10 (0.6%) of dehiscence, 22 (1.6%) of meatal stenosis, 21 (1.5%) of stricture, 6 (0.7%) of diverticulum, and resident curvature in 11 cases (1.2%). The overall complication rate in TIP and free-tube procedure was 9.8 and 9.9%, respectively, and fistula occurred in primary TIP of 33 cases (4.9%). Conclusions: Buck's fascia with the glans can be used as an integral covering technique in one-stage distal to proximal hypospadias and primary or re-operative hypospadias repair. It is safe, feasible, and effective for the repair of hypospadias.
