Abstract
OBJECTIVE The purpose of this first french guideline is to provide a clinical framework for the diagnosis, treatment and follow-up of anterior urethral strictures. The statements are established by the subgroup working on uro-genital reconstruction surgery (GURU) from the CAMS-AFU (Andrology and Sexual Medicine Committee from the French Association of Urology). MATERIAL AND METHODS These guidelines are adapted from the Male Urethral Stricture : American Urological Association Guideline 2016, updated by an additional bibliography from January 2016 to December 2019. Twenty-seven main scenarios seen in clinical practice are identified: from diagnosis, to treatment and follow-up. In addition, this guidelines are powered by anatomical diagrams, treatment algorithms, summaries and follow-up tables. RESULTS Anterior urethral strictures are a common condition (0,1 à 1,4 %) in men. The diagnosis is based on a trifecta including an examination with patient reported questionnaires, urethroscopy and retrograde urethrography with voiding cystourethrography. Short meatal stenosis can be treated by dilation or meatotomy, otherwise a urethroplasty can be performed. First line treatment of penile strictures is urethroplasty. Short bulbar strictures (<2cm) may benefit from endourethral treatment (direct visual internal urethrotomy or dilation). In case of recurrence or when the stenosis measures more than 2 cm, a urethroplasty will be proposed. Repeated endourethral treatment management are no longer recommended except in case of palliative option. Urethroplasty is usually done with oral mucosa graft as the primary option, in one or two stages approach depending on the extent of the stenosis and the quality of the tissues. Excision and primary anastomosis or non-transecting techniques are discussed for bulbar urethra strictures. Follow-up by clinical monitoring with urethroscopy, or retrograde urethrography with voiding cystourethrography, is performed at least the first year and then on demand according to symptoms. CONCLUSION Anterior urethral strictures need an open surgical approach and should be treated by urethroplasty in most cases. This statement requires a major paradigm shift in practices. Training urologist through reconstructive surgery is the next challenge in order to meet the demand.

Free Graft Augmentation Urethroplasty for Bulbar Urethral Strictures: Which Technique Is Best? A Systematic Review. Eur Urol 2021; 80:57-68. [PMID: 33875306 DOI: 10.1016/j.eururo.2021.03.026] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2020] [Accepted: 03/24/2021] [Indexed: 01/17/2023]
Abstract
CONTEXT Four techniques for graft placement in one-stage bulbar urethroplasty have been reported: dorsal onlay (DO), ventral onlay (VO), dorsolateral onlay (DLO), and dorsal inlay (DI). There is currently no systematic review in the literature comparing these techniques. OBJECTIVE To assess if stricture recurrence and secondary outcomes vary between the four techniques and to assess if one technique is superior to any other. EVIDENCE ACQUISITION The EMBASE, MEDLINE, and Cochrane Systematic Reviews-Cochrane Central Register of Controlled Trials (CENTRAL; Cochrane HTA, DARE, HEED) databases and ClinicalTrials.gov were searched for publications in English from 1996 onwards. Randomised controlled trials (RCTs), nonrandomised comparative studies (NRCSs), observational studies (cohort, case-control/comparative, single-arm), and case series with ≥20 adult male participants were included. EVIDENCE SYNTHESIS A total of 41 studies were included involving 3683 patients from one RCT, four NRCSs, and 36 case series. Owing to the overall low quality of the evidence, a narrative synthesis was performed. CONCLUSIONS No single technique appears to be superior to another for bulbar free graft urethroplasty. Both DO and VO are suitable for bulbar augmentation urethroplasty, with a ≤20% recurrence rate over medium-term follow-up. No recommendations can be made regarding DI or DLO techniques owing to the paucity of evidence. Secondary outcomes including sexual function, and complications are infrequently reported. Recurrence rates deteriorate in the long term for both DO and VO procedures. PATIENT SUMMARY We reviewed the evidence for four different skin-graft techniques used to repair narrowing of a section of the urethra (bulbar urethra, under the scrotum and perineum) in men. Two of the techniques seem to give consistent results, with recurrence rates lower than 20%. Recurrence rates increase over time, so patients should continue to monitor their symptoms. There is poorer reporting of other outcomes such as sexual function, urinary symptoms, and complications, and it is possible that these occur more frequently than the current data suggest.

Abstract
OBJECTIVE The objective is to summarize and characterize the long-term success of anterior augmentation urethroplasty (AU) in published series. The current literature on AU consists largely of retrospective series reporting intermediate follow-up and incompletely characterize the long term outcomes of AU. MATERIALS AND METHODS A systematic literature review was performed consistent with PRISMA guidelines to characterize long-term outcomes of AU with a minimum upper limit follow-up of 100 months. Penile/preputial skin flaps and graft and oral mucosal graft urethroplasties were included. The primary outcome was stricture-free survival for one-stage AU. Secondary analysis evaluated differences in outcomes based on two failure definitions: the need for intervention versus presence of recurrent stricture on cystoscopy or urethrography. Hazard rates were induced from the reported failure rates of one-stage AU and fixed and random effect models were fitted to the data. Additional subset analysis, removing potential confounders (lichen sclerosus, hypospadias and penile skin graft), was performed. RESULTS Ten studies met inclusion criteria, and two studies reported separate outcomes for grafts and flaps, and thus were included separately in the analysis. The mean hazard rate across all studies was 0.0044, the corresponding survival rates at 1 year 0.948, 5 years 0.766, 10 years 0.587, and 15 years 0.45. Subset analysis of the 4 select and homogeneous studies noted 1, 5, 10, and 15 years survival rates of 0.97, 0.96, 0.74, and 0.63, respectively. CONCLUSIONS The long-term success rates of augmentation urethroplasty are appear to be worse than previously appreciated and patients should be counseled accordingly.

Abstract
Background Long anterior urethral stricture due to variable etiological factors constitutes a challenge for reconstruction. We evaluated our centers experience with cases of long anterior urethral stricture due to different etiologies that were managed by 2-stage substitution urethroplasty using buccal mucosal graft procedure. Methods During the period between November 2009 and November 2016. All cases with long anterior urethral stricture that were planned for substitution urethroplasty in our department were enrolled in this study. The first stage was excision of most fibrotic areas of the urethral plate, the remaining of the urethra is laid open and augmented with buccal mucosal graft for second stage closure after 6–9 months. Results The study included 123 patients who underwent first stage, 105 patients of them underwent second stage urethroplasty. Eighteen cases were missed after first stage. The mean (range) age was 38.4 (17–60 years). The mean (range) stricture length was 8.3 (4–13 cm). The cause of stricture was idiopathic in 47, inflammatory in 15, lichen sclerosus in 26 and post failed hypospadias repair in 35 patients. First stage was complicated by graft contracture in 11 (8.9%) patients that needed re-grafting, 5(4.1%) patient had bleeding from the buccal mucosa site that needed haemostatic sutures, oral numbness was reported in 7 (5.7%) patients. Second stage was complicated by wound dehiscence in 2(1.9%) patients, restricture in 11 (10.5%), fistula in 6 (5.7%) patients, meatal stenosis in 3 (2.9%). The overall success rate was 79.1% (83 cases out of 105) with a mean (range) follow-up of 34.7 (10–58 months). Conclusions Staged urethroplasty using buccal mucosal graft procedure is an effective surgical option for patients with long anterior urethral strictures especially for patients with lichen sclerosus and those with failed previous surgical repair.

Abstract
Urethral stricture/stenosis is a narrowing of the urethral lumen. These conditions greatly impact the health and quality of life of patients. Management of urethral strictures/stenosis is complex and requires careful evaluation. The treatment options for urethral stricture vary in their success rates. Urethral dilation and internal urethrotomy are the most commonly performed procedures but carry the lowest chance for long-term success (0–9%). Urethroplasty has a much higher chance of success (85–90%) and is considered the gold-standard treatment. The most common urethroplasty techniques are excision and primary anastomosis and graft onlay urethroplasty. Anastomotic urethroplasty and graft urethroplasty have similar long-term success rates, although long-term data have yet to confirm equal efficacy. Anastomotic urethroplasty may have higher rates of sexual dysfunction. Posterior urethral stenosis is typically caused by previous urologic surgery. It is treated endoscopically with radial incisions. The use of mitomycin C may decrease recurrence. An exciting area of research is tissue engineering and scar modulation to augment stricture treatment. These include the use of acellular matrices or tissue-engineered buccal mucosa to produce grafting material for urethroplasty. Other experimental strategies aim to prevent scar formation altogether.

Abstract
OBJECTIVE To describe the safety, feasibility and outcome of redo buccal mucosal graft urethroplasty in patients presenting with recurrent anterior urethral stricture following previous failed BMG urethroplasty. MATERIALS AND METHODS This was a retrospective chart review of 21 patients with recurrent anterior urethral stricture after buccal mucosal graft urethroplasty, who underwent redo urethroplasty at our institute between January 2008 to January 2014. All patients underwent preoperative evaluation in the form of uroflowmetry, RGU, sonourethrogram and urethroscopy. Among patients with isolated bulbar urethral stricture, who had previously undergone ventral onlay, redo dorsal onlay BMG urethroplasty was done and vice versa (9+8 patients). Three patients, who had previously undergone Kulkarni-Barbagli urethroplasty, underwent dorsal free graft urethroplasty by ventral sagittal urethrotomy approach. One patient who had previously undergone urethroplasty by ASOPA technique underwent 2-stage Bracka repair. Catheter removal was done on 21(st) postoperative day. Follow-up consisted of uroflow, PVR and AUA-SS. Failure was defined as requirement of any post operative procedure. RESULTS Idiopathic urethral strictures constituted the predominant etiology. Eleven patients presented with stricture recurrence involving the entire grafted area, while the remaining 10 patients had fibrotic ring like strictures at the proximal/distal graft-urethral anastomotic sites. The success rate of redo surgery was 85.7% at a mean follow-up of 41.8 months (range: 1 yr-6 yrs). Among the 18 patients who required no intervention during the follow-up period, the graft survival was longer compared to their initial time to failure. CONCLUSION Redo buccal mucosal graft urethroplasty is safe and feasible with good intermediate term outcomes.

Abstract
Asopa described the inlay of a graft into Snodgrass’s longitudinal urethral plate incision using a ventral sagittal urethrotomy approach in 2001. He claimed that this technique was easier to perform and led to less tissue ischemia due to no need for mobilization of the urethra. This approach has subsequently been popularized among reconstructive urologists as the dorsal inlay urethroplasty or Asopa technique. Depending on the location of the stricture, either a subcoronal circumferential incision is made for penile strictures, or a midline perineal incision is made for bulbar strictures. Other approaches for penile urethral strictures include the non-circumferential penile incisional approach and a penoscrotal approach. We generally prefer the circumferential degloving approach for penile urethral strictures. The penis is de-gloved and the urethra is split ventrally to exposure the stricture. It is then deepened to include the full thickness of the dorsal urethra. The dorsal surface is made raw and grafts are fixed on the urethral surface. Quilting sutures are placed to further anchor the graft. A Foley catheter is placed and the urethra is retubularized in two layers with special attention to the staggering of suture lines. The skin incision is then closed in layers. We have found that it is best to perform an Asopa urethroplasty when the urethral plate is ≥1 cm in width. The key to when to use the dorsal inlay technique all depends on the width of the urethral plate once the urethrotomy is performed, stricture etiology, and stricture location (penile vs. bulb).

Abstract
Background Anterior urethral stricture remains a great challenge. We reported our clinical technique and results by using inlay dorsal buccal mucosal graft urethroplasty for repair of anterior urethral stricture. Methods From January 2005 to July 2008, 87 male patients (range from 9 to 72 years old) with anterior urethral stricture have been treated by one-stage dorsal inlay oral mucosal graft (OMG) urethroplasty. All patients gave written informed consent for their participation. All patients showed that urethral plate had been either scarred or removed previously. In our surgery, the urethra was dissected dorsally and scar of the urethral plate was removed. The remnant urethral plate was split at midline and a buccal mucosa patch was inserted between the two parts. Neourethra was tubularized and covered with dartos flap. The pre-operative assessments included clinical data, urine analysis, uroflowmetry, retrograde and voiding cystogram, urethral ultrasonography and endoscopy. Postoperatively, the flow rate and void residual volume were analyzed by uroflowmetry and sonography. Any further instrumentation to assist voiding was considered as failure. Results After 12 to 48 months (mean: 25.8 months), 78 patients (89.66%) have shown good results by the one-stage urethroplasty. However, 9 patients (10.3%) required further treatment due to recurrence, while 6 patients (6.9%) had fistula. Conclusions This one-stage dorsal inlay approach using dorsal oral mucosal grafts is a reliable method to create a substitute urethral plate for tubularization. This approach represents a safe option for anterior urethral stricture patients especially with grossly scarred urethral plate.

Abstract
OBJECTIVE To determine the overall efficacy and predictors of success of the penile preputial flap in the management of complex urethral strictures >2.5 cm in length. PATIENTS AND METHODS We performed a retrospective and prospective study of 58 patients undergoing single-stage penile preputial flap urethroplasty for complex long-segment urethral strictures, without lichen sclerosus, repaired between May 2005 and April 2012 at our institution. For obvious reasons circumcised patients were excluded from the study. Results were assessed by univariate analysis of various patient characteristics, preoperative and postoperative patient satisfaction (based on symptoms), and urethral ultrasonography, retrograde urethrography and uroflowmetry. RESULTS The median (range) follow-up was 42 (6-90) months, the median (range) intra-operative stricture length was 48.5 (26-85) mm and the median (range) operating time was 90 (85-125) min. A total of 87.93% of patients had a satisfactory outcome, with an overall success rate of 81.03%. Diabetes mellitus (relative risk [RR] 5.21, confidence interval [CI] 2.31-64.68, P = 0.003) and smoking (RR 4.19, CI 1.54- 45.0, P = 0.01) were predictors of failure, while postinfective aetiology (RR 2.19), panurethral stricture (RR 2.73), stricture length >70 mm (RR 3.25), previous urethroplasty (RR 2.4) and severe peri-urethral fibrosis (RR 2.37) were also associated with a higher risk of failure. CONCLUSIONS A urologist should try to gain experience of all the methods of urethroplasty as the techniques may vary according to the circumstances. Single-stage preputial skin flap urethroplasty, in experienced and expert hands, has results equivalent to all other methods of urethroplasty in complex urethral strictures. We prefer this technique in this part of the world where buccal mucosa cannot be used because of dyskeratotic changes as a result of consumption of gutkha, tobacco, pan masala, betel nut.

Abstract
Objectives. To evaluate the results of one-stage buccal mucosal urethroplasty in treatment of long urethral strictures. Methods. This retrospective study was carried out on 117 patients with long urethral strictures who underwent one-stage transperineal urethroplasty with dorsally placed buccal mucosal grafts (BMG). Success was defined as no need for any intervention during the follow-up period. Results. Among 117 patients with mean age of 39.55 ± 15.98 years, the strictures were located in penile urethra in 46 patients (39.32%), bulbar urethra in 33 (28.20%) and were panurethral in 38 (32.48%). The etiology of the urethral stricture was sexually transmitted disease (STD) in 17 (14.53%), lichen sclerosus in 15 (12.82%), trauma in 15 (12.82%), catheterization in 13 (11.11%), transurethral resection (TUR) in 6 (5.13%), and unknown in 51 (43.59%). The mean length of strictures was 9.31 ± 2.46 centimeters. During the mean followup of 18.9 ± 6.7 months success rate was 93.94% in bulbar strictures, 97.83% in penile strictures, and 84.21% in panurethral strictures (P value: 0.061). Conclusions. The success rate of transperineal urethroplasty with dorsally placed buccal mucosal grafts is equal in different sites of strictures with different etiologies. So reconstruction of long urethral strictures may be safely and effectively performed at a simple single operative procedure using this method of urethroplasty.

Abstract
Male urethral stricture disease is prevalent and has a substantial impact on quality of life and health-care costs. Management of urethral strictures is complex and depends on the characteristics of the stricture. Data show that there is no difference between urethral dilation and internal urethrotomy in terms of long-term outcomes; success rates range widely from 8-80%, with long-term success rates of 20-30%. For both of these procedures, the risk of recurrence is greater for men with longer strictures, penile urethral strictures, multiple strictures, presence of infection, or history of prior procedures. Analysis has shown that repeated use of urethrotomy is not clinically effective or cost-effective in these patients. Long-term success rates are higher for surgical reconstruction with urethroplasty, with most studies showing success rates of 85-90%. Many techniques have been utilized for urethroplasty, depending on the location, length, and character of the stricture. Successful management of urethral strictures requires detailed knowledge of anatomy, pathophysiology, proper patient selection, and reconstructive techniques.

Abstract
The use of oral mucosa for urethral stricture repair has become the standard approach in reconstructive urethral surgery. Compared to other tissues oral mucosa shows several advantages, such as simple harvesting, good urine tolerance and low harvesting morbidity. For defects of the male bulbar urethra measuring 2 cm or longer, urethral reconstruction with oral mucosa is the procedure of choice. The oral mucosa graft can be used as an inlay or as an onlay graft. Most repairs can be completed in one stage but for complex strictures two stages are needed.

Abstract
OBJECTIVE To review the outcome of bulbar urethroplasty using two stage surgical techniques. MATERIAL AND METHODS Twenty-two of the 35 patients studied corresponded to end-to-end urethroplasty (ATT) and 13 to dorsal onlay graft (DOG) in preputial skin or oral mucosa variants. Clinical outcome was considered a failure when postoperative surgery was needed or the uroflowmetry was less than 15ml/s. The following variables were studied: age, previous surgery, number of urethrotomies and stricture length. The curves and log-rank Curves using the log-rank were elaborated for follow-up and comparison, with the Cox regression model for risk factors. RESULTS Mean follow-up was 40.02 months. Of all the cases. 85.71% were successful. Of these, 86.36% were in the ATT group and 84.61% in the DOG group. There were no significant differences in the comparative LR test based in stricture length, previous surgery between both group and individualized for each management. The Cox regression model showed a risk of failure in the technique for the elderly patients (OR 2.2), it not achieving statistical significance in the remaining variables. CONCLUSIONS The success rate achieved with the ATT technique is verified a gold standard option in short strictures. The DOG is shown as a valid option in long strictures in bulbar urethral in medium follow-up, using a oral mucosa or preputial onlay graft. More long-term follow-up must be performed with a greater number of patients to better evaluate these results.

Abstract
We performed an overview of the surgical techniques suggested for the treatment of anterior urethral strictures using MEDLINE. In applying the MEDLINE search, we used the ″MeSH″ (Medical Subject Heading) and "free text" protocols. The MeSH search was conducted by combining the following terms: "urethral stricture", "flap", "graft", "oral mucosa", "urethroplasty", "urethrotomy" and "failed hypospadias". Multiple "free text" searches were performed individually applying the following terms through all fields of the records: "reconstructive urethral surgery", "end-to-end anastomosis", "one-stage", "two stage". Descriptive statistics of the articles were provided. Meta-analyses were not employed. Seventy-eight articles were determined to be germane in this review. Six main topics were identified as controversial in anterior urethra surgery: the use of oral mucosa vs penile skin; the use of free grafts vs pedicled flaps in penile urethroplasty; the use of grafts vs anastomotic repair in bulbar urethral strictures; the use of dorsal vs ventral placement of the graft in bulbar urethroplasty; the use of definitive perineal urethrostomy vs one-stage repair in complex urethral strictures; the surgical options for patients with failed hypospadias repair. Different points of view are documented and presented in the literature by various authors from different countries. The aim of this clinical overview is to survey the main controversial issues in surgical reconstruction of the anterior urethra focusing on the use of flap or graft, substitute material, type of surgery and challenging situations, such as failed hypospadias or complex urethral stricture repair.

Abstract
Objectives To describe our experience with ‘minipatch’ penile skin graft (PSG) urethroplasty, as at our institution we prefer excision and primary anastomosis (EPA) urethroplasty whenever feasible, as it gives better outcomes than substitution urethroplasty. However, despite careful preoperative planning, the unanticipated need for a small graft is occasionally recognised intra-operatively, and in such cases we have found that harvesting a minipatch is an efficient alternative to harvesting a buccal mucosal graft. Patients and methods Bulbar urethroplasty using a <3 cm PSG was performed via either a ventral onlay or augmented anastomotic technique. In each case the PSG was required to repair an unanticipated urethral defect recognised intra-operatively during various scenarios of challenging urethroplasty. We retrospectively reviewed our experience with this technique. Results Among a total of 425 urethral reconstructions over a 4-year period at our institution, four patients (1%) underwent minipatch PSG urethroplasty to repair either urethral strictures that were discovered intra-operatively to be too complex for EPA (two patients) or for intra-operatively identified, unanticipated synchronous strictures (two patients). The mean (range) stricture length was 2.4 (2–3) cm and the mean graft length was 2.1 (1.5–2.5) cm. At a mean follow-up of 18 months all repairs were patent with no need for further procedures or instrumentation. Conclusion Minipatch PSG urethroplasty is an efficient alternative to a buccal mucosal graft repair, especially when the unanticipated need for short-segment tissue transfer arises during complex urethral reconstruction.

Abstract
UNLABELLED Study Type--Therapy (case series) Level of Evidence 4. What's known on the subject? and What does the study add? For long complex anterior urethral stricture augmentation urethroplasty is considered the standard procedure but the best substitute material is still to be ascertained. Preputial/penile skin is a very good substitute especially when used as a dorsal onlay. It demonstrates exceptional functional and cosmetic results even in patients with unsuitable oral mucosa. OBJECTIVE • To present our experience of single-stage reconstruction of urethral stricture with preputial/penile skin flap, as a dorsal onlay flap (DOF) where there is an adequate urethral plate and as a tubularized flap (TF) where there is a compromised urethral plate, in cases of complex anterior urethral strictures. MATERIALS AND METHODS • We retrospectively reviewed 144 patients, who underwent single-stage repair of pendular /bulbar urethral strictures with preputial/penile flap as either a DOF or a TF, between January 2001 and December 2008. • Patients were divided into three groups: Group 1 consisted of patients who underwent transverse preputial DOF; Group 2 consisted of those who underwent tube urethroplasty; and Group 3 consisted of those patients who were circumcised and for whom the penile skin was used as a DOF (circumpenile flap). • Patients were followed up by physical examination, retrograde urethrography, uroflowmetry and post-void residual urine measurement. RESULTS • The mean follow-up was 40.1 months (range 36-84 months). • The primary success rates at 1 year follow-up were 90, 85 and 93.3% for Groups1, 2 and 3, respectively, and at 3-years follow-up they were 85, 75 and 86.7%, respectively. • Half of the recurrences were successfully managed with a single visual internal urethrotomy or dilatation. • The secondary success rate was defined as recurrent stricture managed by a single endoscopic procedure and was 5, 10 and 6.8% in Groups 1, 2 and 3, respectively. The overall success rate was 90.85 and 93.3%, respectively. • A total of 75% of the patients in the study completed 60 months of follow-up with no additional recurrence. CONCLUSIONS • A preputial/penile flap for complex anterior urethral stricture is a good treatment option, with results similar to other techniques, has acceptable donor site morbidity and is effective even in circumcised patients and for those patients with unsuitable oral mucosa. • A DOF is less likely to lead to diverticula formation and post-void dribbling. TFs have a higher failure rate than DOFs but, when combined judiciously with secondary endoscopic procedures, can provide good results.

Abstract
Objective: To present the outcome of dorsal onlay urethroplasty in 73 patients for stricture urethra over a period of eight years. Materials and Methods: Seventy-three patients of stricture urethra have undergone dorsal onlay urethroplasty from July 1998 to February 2006. Age distribution: 14-58 years. Etiology: Trauma 20/73 (27.39%), Balanitis Xerotica Obliterans 2/73 (2.73%), Iatrogenic 26/73(35.61%), Infection 3/73 (4.10%), Idiopathic 22/73 (30.13%). Site: Penobulbar-25/73, bulbar-38/73, membranous-8/73 and long length-2/73. Suprapubic catheter was inserted preoperatively: 21/73 patients. Preputial / distal penile skin was used in all patients. Buccal mucosa was not used in any patient. Hospitalization was for four to five days. Catheter was removed after 21 days. All patients had their first endoscopic checkup after three months. Subsequently they were followed up by uroflometry. Routine imaging of urethra for follow-up was not carried out. Results: 63/73 (86.30%) patients had satisfactory outcome not requiring any further treatment, 8/73 (10.95%) developed anastomotic stricture (3/8-optical internal urethrotomy, 5/8 dilatation alone). 2/73 (2.75%) developed external meatal stenosis. None had urinary fistula and required repeat urethroplasty. Follow-up ranged from three months to eight years. Conclusion: Dorsal onlay urethroplasty using preputial/distal penile skin is a satisfactory procedure. Preputial/distal penile skin is devoid of hair and fat and hence an ideal graft material. Even in circumscribed patients distal penile skin can be harvested. Long-term follow-up is required in judging results of patients with stricture urethra.

Abstract
CONTEXT Reconstructive surgeons who perform urethroplasty have a variety of techniques in their armamentarium that may be used according to factors such as aetiology, stricture position, and length. No one technique is recommended. OBJECTIVE Our aim was to assess the reported outcomes of the various techniques for graft augmentation urethroplasty according to site of surgery. EVIDENCE ACQUISITION We performed an updated systematic review of the Medline literature from 1985 to date and classified the data according to the site of surgery and technique used. Data are also presented on the type of graft used and the follow-up methodology used by each centre. EVIDENCE SYNTHESIS More than 2000 anterior urethroplasty procedures have been described in the literature. When considering the bulbar urethra there is no significant difference between the average success rates of the dorsal and the ventral onlay procedures, 88.4% and 88.8% at 42.2 and 34.4 mo in 934 and 563 patients, respectively. The lateral onlay technique has only been described in six patients and has a reported success rate of 83% at 77 mo. The Asopa and Palminteri techniques have been described in 89 and 53 patients with a success rate of 86.7% and 90.1% at 28.9 and 21.9 mo, respectively. When considering penile strictures, the success rate of the two-stage penile technique is significantly better than the one-stage penile technique, 90.5% versus 75.7% as calculated for 129 and 432 patients, respectively, although the follow-up of one-stage procedures was longer at 32.8 mo compared with 22.2 mo. CONCLUSIONS There is no evidence in the literature of a difference between one-stage techniques for urethroplasty of the bulbar urethra. The two-stage technique has better reported outcomes than a one-stage approach for penile urethroplasty but has a shorter follow-up.

Abstract
PURPOSE To report our extended experience with single-stage genital skin graft urethroplasty for complex hypospadias reoperations. MATERIALS AND METHODS Thirty-one patients with failed hypospadias surgery were included. The urethral plate had been removed or was scarred in all. After excision of fibrotic tissue a free full-thickness skin graft was quilted to the corpora cavernosa. The neourethra was then tubularized followed by glanuloplasty. Voiding cystograms, urethral ultrasound and flow measurements were performed in all. Outcome was considered a failure when postoperative instrumentation was needed. RESULTS Follow up was 78.45 +/- 18.18 months. Shaft skin was used in 13 and internal prepuce in 18. Average graft length was 3.66 +/-1.56cm. Eighteen patients required glanuloplasty. Initial graft healing was successful in all. There was no postoperative infection involving the inlay. We did not note complications from the graft donor sites. Four patients underwent redo surgery yielding a complication rate of 12.9%. Urethral stricture of the proximal anastomosis was most frequent. CONCLUSIONS This single-stage approach using dorsal inlay skin grafts is reliable, creating a substitute urethral plate in the long term. Complication rates are equivalent to those of staged strategies. This is a safe option for hypospadias reoperations if the urethral plate is compromised.

Abstract
CONTEXT There is no clear evidence that determines which type of urethroplasty to perform under which particular circumstance. OBJECTIVE To review the options for urethroplasty at different sites in the urethra and for different types of stricture indicating which procedure should be used in which circumstances according to the best available evidence. EVIDENCE ACQUISITION Recent publications have been reviewed and supplemented with the authors' personal experience. EVIDENCE SYNTHESIS Currently, in the developed world, the most common types of stricture are relatively short and are situated in the bulbar urethra. There is good evidence that these are best treated by excision and end-to-end anastomosis if they are short enough or by patch urethroplasty using a buccal mucosal graft if they are longer. Distal penile urethral strictures are the next most common type of stricture, but the evidence base is weaker, although there is agreement that penile strictures due to lichen sclerosus often require a staged approach to reconstruction, again using buccal mucosal grafts. Urethroplasty for pelvic fracture urethral injury is an altogether different type of technique for an altogether different type of pathology. There is good evidence that this is best treated by bulbo-prostatic anastomotic urethroplasty. Other types of strictures and salvage surgery have no good evidence base and are specialised areas where experience and judgement are necessary. CONCLUSIONS The evidence base for urethral surgery has been developed for the more common types of urethral strictures in the last 20 yr, but it is still as much an art as it is a science.

Abstract
PURPOSE We determined the overall efficacy and predictors of success of the distal penile circular fasciocutaneous flap in the management of complex anterior urethral stricture disease not due to lichen sclerosus. MATERIALS AND METHODS We performed a retrospective review of all patients undergoing reconstruction of complex anterior urethral strictures without lichen sclerosus repaired from 1985 to 2006. Primary and overall stricture-free survival curves were estimated using the Kaplan-Meier method. Cox proportional hazards regression analysis was used to identify univariate and multivariate predictors of flap success. RESULTS A total of 124 patients met the inclusion and exclusion criteria. Median patient age was 48 years (range 16 to 83). Median followup was 7.3 years (range 1 month to 19.5 years). Median stricture length was 8.2 cm (range 0.5 to 24). At 1, 3, 5 and 10 years the overall estimated stricture-free survival rates were 95%, 89%, 84% and 79%, respectively. On multivariate analysis smoking (HR 4.0, 95% CI 1.2-12.9, p = 0.02), history of hypospadias repair (HR 4.4, 95% CI 1.3-14.6, p = 0.01) and stricture length 7 to 10 cm (HR 7.0, 95% CI 1.4-34.7, p = 0.02) were predictive of failure. CONCLUSIONS Fasciocutaneous flap urethroplasty has good and durable success rates in the treatment of complex anterior urethral strictures. Predictors of failure included smoking, history of hypospadias repair and longer stricture length.

Randomized comparative study between buccal mucosal and acellular bladder matrix grafts in complex anterior urethral strictures. J Urol 2008; 179:1432-6.

Abstract
PURPOSE Urethral strictures have been a reconstructive dilemma for many years due to the limited availability of tissue substitutes and incidence of recurrence. Buccal mucosal grafts have been a favored material in instances where penile skin is unavailable due to its durability and excellent graft survival. Recently collagen based matrices derived from the bladder have been used successfully in patients with stricture disease and hypospadias. We performed a randomized comparative study to assess the outcome of the acellular bladder matrix compared to buccal mucosa in patients with complex urethral strictures. MATERIALS AND METHODS Human demineralized bone matrix, obtained from cadaveric donors, was processed and prepared for use as an off-the-shelf material. Thirty patients with stricture 21 to 59 years old (mean 36.2) were enrolled and assessed using a standard protocol. The stricture length ranged from 2 to 18 cm (mean 6.9), of which 11 patients had bulbar, 7 had pendulous and 12 had combined bulbopendulous strictures. Of the 30 patients 7 had received no previous intervention while the remaining 23 had undergone 1 to 7 procedures (mean 1.9). All patients were randomized and alternatively assigned to receive either buccal mucosa or decellularized bladder [corrected] matrix and underwent an onlay procedure. RESULTS All patients except 2 who were lost during followup were followed for 18 to 36 months (mean 25). In patients with a healthy urethral bed (less than 2 prior operations) the success rate of buccal mucosa grafts (10 of 10) was similar to the bladder matrix grafts (8 of 9) in terms of patency. In patients with an unhealthy urethral bed (more than 2 prior operations) only 2 of 6 patients with a bladder matrix graft were successful, whereas all 5 patients with a buccal mucosa graft had a patent urethra. Postoperative uroflowmetry showed significant voiding improvement in both groups. Histology of the graft biopsies showed normal urethral tissue characteristics. CONCLUSIONS This study demonstrates that the use of acellular bladder matrix is a viable option for urethral repair. Demineralized bone matrix as an off-the-shelf biomaterial achieves the best results in patients with a healthy urethral bed, no spongiofibrosis and good urethral mucosa.

Abstract
OBJECTIVES To report retrospectively long-term follow-up in a homogeneous group of patients who underwent dorsal onlay skin graft bulbar urethroplasty and to investigate which factors might influence long-term outcome. METHODS Thirty-eight patients, with an average age of 43 yr, underwent dorsal onlay skin graft (#12 ventral penile skin and #26 preputial mucosa) bulbar urethroplasty from 1994 to 2000. Of 38 patients, 23 (60.5%) had undergone prior endoscopic procedures. Preoperative evaluation included clinical history, physical examination, retrograde and voiding urethrography, and urethral sonography. Three weeks after surgery, voiding cystourethrography was performed. Patients were followed-up with a clinical evaluation and specific diagnostic tests every 4 mo in the first year and every 12 mo thereafter. Clinical outcome was considered a failure when postoperative instrumentation, including dilation, was needed. RESULTS Average follow-up was 111 mo (range, 80-149). Of 38 cases, 25 (65.8%) were successful and 13 (34.2%) failures. Patients with stricture length > 6 cm and a previous history of urethrotomies or dilatations seemed to have a higher risk of failure, but this observation was only a trend and did not reach levels of statistical significance. CONCLUSIONS Penile skin used as dorsal onlay graft for bulbar urethral reconstruction in a homogeneous series of patients showed a success rate ranging from 90% at short-term follow-up to 66% after long-term follow-up. There was no evidence for particular risk factors (length of stricture, number of dilatations and urethrotomies) for failure.

Abstract
OBJECTIVE To report our initial experience and extended follow-up of single-stage dorsal inlay skin-graft urethroplasty for salvaging recurrent anterior urethral stricture (AUS), as urethral reconstruction remains a challenge, particularly in patients with recurrent AUS after previous surgery, and a paucity of local skin frequently requires free graft reconstruction techniques. PATIENTS AND METHODS In all, 27 patients (mean age 48.12 years, range 17-79) with recurrent AUS had a dorsal inlay urethroplasty using extragenital split-thickness skin grafts. An electrical dermatome was used for graft harvesting. All patients had contraindications for buccal mucosal grafting (e.g. radiotherapy, leukoplakia). The assessment before repair comprised a clinical investigation, urine analysis, uroflowmetry, retrograde and voiding cystogram, urethral ultrasonography and endoscopy. The follow-up was based on an assessment of flow rate and postvoid residual volume. Success was defined by the absence of symptoms and stable maximum flow rate, while any further instrumentation was considered a failure. RESULTS The mean (range) stricture length was 8.35 (3-14) cm. The overall complication rate was 7%, with no complications during surgery. During the mean (range) follow-up of 32.43 (5-46) months, 25 (93%) of the patients were successfully cured in one operation. Two patients required further treatment for recurrence and fistula. No long-term complications were noted at the graft donor sites. There was no case of intraurethral hair growth during the extended follow-up. CONCLUSION If there are contraindications for buccal mucosal grafting, a split-thickness skin can be used for dorsal inlay urethroplasty in recurrent AUS. A well-vascularized recipient bed on the corpora cavernosa is required for reliable graft take. Intra-urethral hair growth is avoided by using split-skin grafts. Although the complication rates are equivalent to those of buccal mucosa, we await the longer follow-up to assess the ultimate value of this alternative single-stage technique.

Abstract
We performed an up-to-date review of the surgical techniques suggested for the treatment of anterior urethral strictures. References for this review were identified by searching PubMed and MEDLINE using the search terms "urethral stricture" or "urethroplasty" from 1995 to 2006. Descriptive statistics of the articles were provided. Meta-analyses or other multivariate designs were not employed. Out of 327 articles, 50 (15%) were determined to be germane to this review. Eight abstracts were referenced as the authors of this review attended the meetings where the abstract results were presented, thus it was possible to collect additional information on such abstracts. Urethrotomy continues to be the most commonly used technique, but it does have a high failure rate and many patients progress to surgical repair. Buccal mucosa has become the most popular substitute material in urethroplasty; however, the skin appears to have a longer follow-up. Free grafts have been making a comeback, with fewer surgeons using genital flaps. Short bulbar strictures are amenable using primary anastomosis, with a high success rate. Longer strictures are repaired using ventral or dorsal graft urethroplasty, with the same success rate. New tools such as fibrin glue or engineered material will become a standard in future treatment. In reconstructive urethral surgery, the superiority of one approach over another is not yet clearly defined. The surgeon must be competent in the use of various techniques to deal with any condition of the urethra presented at the time of surgery.

Abstract
PURPOSE We provide the reader with a critical, nonbiased, systematic review of current and precedent literature regarding the use of oral mucosa in the reconstruction of urethral defects associated with stricture and hypospadias/epispadias. MATERIALS AND METHODS We reviewed pertinent English literature from January 1966 through August 1, 2006 via the databases MEDLINE/PubMed, the Cochrane Library, and EMBASE Drugs and Pharmacology regarding the use of oral mucosa graft urethroplasty in the reconstruction of urethral defects associated with stricture and hypospadias/epispadias. Bibliographies of pertinent articles were explored for additional important literature. RESULTS Data were stratified among studies that only used oral mucosa graft urethroplasty in the reconstruction of urethral defects associated with stricture, and those that used oral mucosa graft urethroplasty in the reconstruction of urethral defects associated with hypospadias/epispadias. Recipient site success in the reconstruction of defects associated with stricture was significantly associated with the location of graft placement (ventral vs dorsal, p <0.001) when an onlay graft was used. Hypospadias/epispadias recipient site success was significantly associated with the type of graft used (tube vs onlay, p <0.001), and by the site of oral mucosa harvest (labial vs buccal, p <0.001). Other perioperative and patient oriented variables were not significantly associated with success at the recipient site. CONCLUSIONS The oral mucosa is a viable source of donor tissue displaying many characteristics of the ideal urethral graft. There are numerous variations of the oral mucosa graft urethroplasty technique. Herein comparisons are made.

Abstract
OBJECTIVES To report the long-term results and evaluate the effectiveness of the dorsal on-lay preputial graft urethroplasty in patients suffering from anterior urethra strictures. METHODS A total of 21 male patients, mean age 46.3 years (range 17-67), with anterior urethral strictures, underwent the dorsal on-lay preputial graft urethroplasty during the last 8 years, from October 1997 to September 2005. Strictures were located in bulbar urethra in 16 patients and in penile urethra in the remaining 5. The aetiology the stricture was traumatic injury of the anterior urethra in 12 patients and iatrogenic in 9 patients. A direct vision dorsal urethrotomy and the insertion of an urethral Foley catheter right before the procedure, facilitated the corpus spongiosum dissection and the preparation for urethroplasty. A voiding cystogram was performed on the day of urethral catheter removal to exclude extravasation and estimate the postoperative result. RESULTS Mean follow-up time has been 49.9 months (range 6-95) and the outcome was favourable in 15 patients (71.43%). There were 3 recurrences in penile urethra strictures managed conservatively and three in bulbar urethroplasties, treated with internal urethrotomy followed by urethral dilatations. CONCLUSION Our results indicate that dorsal on-lay urethroplasty using preputial graft is an easy to learn and perform procedure, and offers the patient durable results with rather minimal complications.

Abstract
OBJECTIVE To evaluate the effect of urethral reconstructive surgery on sexual drive, erectile function and ejaculation. PATIENTS AND METHODS The study group consisted of 52 men with a median (range) age of 44 (18-79) years who underwent 59 urethral reconstructive procedures for anterior urethral stricture disease between 2001 and 2004. We evaluated sexual functioning using the O'Leary Brief Male Sexual Function Inventory (BMSFI) before and after surgery. RESULTS The mean (sd) follow-up was 22.3 (14.8) months. The mean BMSFI scores were only statistically significantly different for an improvement in ejaculation after surgery (P = 0.04). When separated by age, only the men aged 50-59 years reported decreased erectile function after surgery (P < 0.001) and only those aged <40-49 years reported an improvement in ejaculatory function (P = 0.05). Men at <1 year after surgery reported lower sexual drive (P = 0.025) and erectile function (P = 0.05) than men with longer periods of recovery. CONCLUSIONS The BMFSI is useful for evaluating sexual function after urethroplasty. Overall, the men did not report a decline in erectile function or sexual drive after surgery; however, older men might have a higher incidence of erectile dysfunction after surgery. Erectile function might recover with time. Younger men had the most pronounced improvement in ejaculatory function, but further studies are necessary to evaluate the clinical significance of this.

Abstract
PURPOSE OF REVIEW To present an up-to-date review on the main surgical techniques used to treat urethral strictures. RECENT FINDINGS Anterior urethroplasty can be treated in outpatient surgical settings, thus decreasing the impact of urethroplasty. To improve outcome in adult patients, reconstructive surgeons have learned to apply the principles of hypospadias surgery, such as delicate tissue handling, avoidance of overlapping suture lines, tissue and the development of preputial skin flaps, to adult urethral surgery. Penile skin has been used as a free graft or harvested as a flap for some time, thanks to its location, hairless skin and durability. Since the early 1990s the use of buccal mucosa was introduced in genital reconstructive surgery and has become popular for complex urethral reconstructions. The use of fibrin glue was recently suggested to fix the buccal mucosal graft in a better way and to cover the anastomosis between the graft and urethral plate. SUMMARY Urethral reconstructive surgery is changing rapidly and this change has posed problems for surgeons who see the principles that previously defined their profession becoming obsolete or unworkable. New techniques, new tools, such as fibrin glue, and new engineered material are a part of our future.

Abstract
OBJECTIVES We describe a new surgical technique with the use of fibrin glue for bulbar urethra reconstruction using a dorsal buccal mucosal onlay graft. METHODS Six patients with a mean age of 43 yr underwent bulbar urethroplasty with dorsal onlay buccal mucosal graft and fibrin glue. The urethra was mobilised from the corpora cavernosa and opened along its dorsal surface. The buccal mucosal graft was applied on the corpora cavernosa using 2 ml of fibrin glue. Two interrupted polyglactin 5-0 sutures were used to fix the apices of the graft to the underlying albuginea of the corpora cavernosa. The urethra was rotated back to cover the graft and an adjunctive fibrin glue was injected over the urethra. RESULTS The mean operative time was 100 min (range, 90-120 min). No intraoperative or postoperative complications were observed. Voiding cystourethrography was performed when the catheter was removed 2 wk after surgery. Urine culture, uroflowmetry, and urethrography were repeated after 6 and 12 mo and annually thereafter. Mean follow-up was 16 mo (range, 12-24 mo). No restrictures at the anastomotic sites were demonstrated in any of the patients 6 and 12 mo after surgery. CONCLUSIONS The use of fibrin glue represents a slight but significant step toward perfecting the surgical technique of bulbar urethral reconstruction.

Abstract
OBJECTIVES To define the feasibility of acellular porcine small intestine submucosa (SIS) as a xenograft implant. SIS is commercially available and approved for use in humans. METHODS Five patients underwent open surgery for urethral stricture repair using SIS and a four-layer SIS graft. Two patients had a bulbar stricture and three had a combined penile-bulbar stricture. The median stricture length was 9 cm (range 3.5 to 10). All patients underwent at least one internal urethrotomy. The urethral stricture repair was performed as an onlay urethroplasty. SIS was used to augment the urethral caliber at the stricture site. A catheter and percutaneous cystostomy for drainage were placed. The catheter was removed 10 days after surgery. Three weeks postoperatively, voiding cystourethrography and retrograde urethrography were performed. RESULTS Preoperatively, flow studies were available for 3 patients, in 1 patient voiding was not possible because of urinary retention, and in 1 patient the preoperative flow study was not available (surgery was performed on the basis of the preoperative urethrographic findings). The mean maximal flow rate was 4.2 mL/s (n = 3); the mean value of the mean flow rate was 2.6 mL/s (n = 3). Postoperatively, 1 patient had extravasation, which was treated by prolonged suprapubic drainage. One patient had severe urethritis and one urinary tract infection. Four patients had a recurrent stricture after a mean of 12.4 months (range 3.7 to 17.5). Two patients underwent open repair using buccal mucosa and two refused repeated surgery. CONCLUSIONS In 4 patients, the operation was not successful. Because of the poor results, we discontinued the use of SIS for open urethral stricture repair.

Abstract
PURPOSE We retrospectively reviewed patterns of failure after bulbar substitution urethroplasty. In particular we investigated the prevalence and location of anastomotic fibrous ring strictures occurring at the apical anastomoses between the graft and urethral plate after 3 types of onlay graft techniques. MATERIALS AND METHODS We reviewed the records of 107 patients who underwent bulbar urethroplasty between 1994 and 2004. Mean patient age was 44 years. Patients with lichen sclerosus, failed hypospadias repair or urethroplasty and panurethral strictures were excluded. A total of 45 patients underwent dorsal onlay skin graft urethroplasty, 50 underwent buccal mucosa onlay graft urethroplasty and 12 underwent augmented end-to-end urethroplasty. The clinical outcome was considered a success or failure at the time that any postoperative procedure was needed, including dilation. Mean followup was 74 months (range 12 to 130). RESULTS Of 107 cases 85 (80%) were successful and 22 (20%) failed. Failure in 12 patients (11%) involved the whole grafted area and in 10 (9%) it involved the anastomotic site, which was distal and proximal in 5 each. Urethrography, urethral ultrasound and urethroscopy were fundamental for determining the difference between full-length and focal extension of re-stricture. Failures were treated with multistage urethroplasty in 12 cases, urethrotomy in 7 and 1-stage urethroplasty in 3. Of the patients 16 had a satisfactory final outcome and 6 underwent definitive perineal urinary diversion. CONCLUSIONS The prevalence and location of anastomotic ring strictures after bulbar urethroplasty were uniformly distributed in after 3 surgical techniques using skin or buccal mucosa. Further studies are necessary to clarify the etiology of these fibrous ring strictures.

Abstract
OBJECTIVE To compare the outcomes of dorsal onlay graft urethroplasty using penile skin (PS) or buccal mucosa (BM) free grafts in the repair of adult bulbourethral strictures. METHODS From January 1998 to March 2003, 30 patients with bulbar urethral strictures underwent urethral reconstruction with PS (17) or with BM free graft (13). Follow-up was done at 6, 12 and 18 months postoperatively, and every year subsequently. Success was defined as normalization of IPSS and a stable Q(max) value >20 ml/s. Any further instrumentation for stricture recurrence was considered a failure. RESULTS Mean follow-up was 51 months (20-74). The overall success rate was 80% (85% in the BM and 76% in the PS group). Improvement of uroflowmetry, IPSS and QoL did not show a significant difference between the two groups. A significant improvement of the orgasmic function domain of the IIEF was found in patients treated with a PS graft. Post-operative complications were lip hypoesthesia (30%), retraction of the ventral skin of the penis (7%), post-voiding dribbling (8% with BM graft, and 7%, with PS graft). Six patients, 2 with BM (15%) and 4 with PS graft patch (24%) required further treatment due to stricture recurrence. CONCLUSION Results of PS or BM graft are comparable at 18 month follow-up, although orgasmic function is significantly improved in patients receiving a PS graft. Nevertheless, with extended follow-up, the use of PS seems to be associated with a higher failure rate.
