Urethral carcinoma after skin substitution urethral reconstruction.

Urethral cancer after urethral reconstruction is an under-recognized, uncommon disease associated with significant morbidity and mortality. The survival rates of patients with carcinoma of the bulbar urethra are as low as 20%-30%. Stricture recurrence and unrecognized malignant changes present prior to reconstruction are major risk factors for urethral cancer. Skin substitution urethroplasty is subjected to higher rates of recurrence, which lends to the potential for carcinogenesis. We present a case of a 59-year-old male who underwent multi-stage skin substitution urethroplasty who developed urethral carcinoma 20 years later.

[Non-transecting anastomotic urethroplasty for strictures of the bulbar urethra. Systematic review].

The results of using non-transecting anastomotic urethroplasty in men with bulbous urethral strictures are presented in the review. A total of 25 original publications were found, including 20 foreign and 5 Russian articles. The studies included from 1 to 358 patients who underwent anastomotic urethroplasty without transection of the corpus spongiosum (average number of patients in a study was 54). Etiological factors were indicated in 17 articles. Most studies (10 out of 17) indicated idiopathic etiology as the predominant one. There was no correlation between the results of the procedure and the etiology of urethral stricture. The mean length of urethral stricture in the vast majority of studies was less than 2 cm, and only in a few studies it was larger, with a maximum mean value of 3.9 cm. Postoperative complication rates were reported in 20 studies and ranged from 0% to 23.9% within one study (median 8.4%). In general, mild complications occurred, corresponding to category I-II according to the Clavien-Dindo classification. The incidence of erectile dysfunction was evaluated in 18 studies and ranged from 0% to 23% (average value of 6.5%). The success of non-transecting anastomotic urethroplasty averaged 94.7% (82-100%) with a median postoperative follow-up of 24.5 months (3-150 months). In 9 out of 25 studies, an additional comparison with transecting technique was done. In 6 studies, the superiority of the non-transecting technique in terms of treatment success and preservation of sexual function was found. The obtained results showed the high efficiency and safety of non-transecting anastomotic urethroplasty in case of short strictures of the bulbous urethra.

Routine Imaging After Bulbar Urethral Reconstruction Does Not Impact Surgical Outcomes and May Not Be Necessary.

OBJECTIVE: To assess whether omitting routine post-operative imaging adversely impacts clinical outcomes after bulbar urethroplasty. Contrast imaging is commonly performed prior to catheter removal after urethroplasty but the clinical need for this is unclear. METHODS: This was a matched, case-control analysis comparing patients undergoing routine voiding cystourethrogram (VCUG) prior to catheter removal after bulbar urethroplasty to patients without imaging. Patients were matched with respect to age, stricture etiology, length, and urethroplasty technique. Follow-up consisted of clinical assessment 3 weeks post-operatively for VCUG/catheter removal, cystoscopy at 3-4 months with clinical assessment annually. Outcome measures were 90-day complications (Clavien ≥2) and stricture recurrence (failure to pass a 16-Fr flexible cystoscope on follow-up). Chi-square and Kaplan-Meier analysis were conducted where appropriate. RESULTS: Hundred patients undergoing bulbar urethroplasty with VCUG prior to catheter removal were compared to 100 matched case controls without imaging. Groups did not differ with respect to failed endoscopic treatment (P = .82), prior urethroplasty (P = .09), comorbidities (P = .54), smoking (P = .42), or pre-operative bacteriuria (P = 1.00). The incidence of extravasation in the VCUG group was 2%. Overall 90-day complications were 9.5% and 15 patients developed recurrence with a median follow-up of 174 months. On chi-square analysis, 90-day complications did not differ between patients undergoing VCUG and those without (12% vs 7.0%; P = .34). On log-rank analysis, stricture recurrence did not differ between groups (P = .44). CONCLUSION: Routine imaging with VCUG after bulbar urethroplasty does not influence the risk of post-operative complications or stricture recurrence. Surgeons should consider avoiding this potentially unnecessary examination in routine clinical practice.

The long-term consequences of the hypospadias salvage repair issue.

PURPOSE: To present the long-term results of redo-hypospadias at our tertiary referral center following a failed prior repair. METHODS: One hundred sixty-four individuals with a history of unsuccessful repairs qualified for our retrospective cohort study. Our inclusion criteria were as follows: pre-operative data that was accessible, redo-hypospadias that was successfully repaired, and at least three years of follow-up at the last hospital visit. RESULTS: The mean patient age was 91.3 ± 21.1 months. The mean follow-up after successful repair was 41.3 ± 3.1 months. Ninety-two (group A) had one prior repair, and 72 (group B) had 2 or 3 repairs. Group A underwent six primary techniques: 32 underwent Onlay Island Flap (OIF), 10 underwent Mathieu, 12 underwent Tubularized Incised Plate Urethroplasty (TIPU), 8 underwent Urethral Mobilization (UM), and 34 underwent Buccal Mucosal Graft (BMG) { dorsal inlay Graft Urethroplasty (DIGU) in 4 and staged BMG in 30 patients}. In group B, four procedures were used: TIPU in 4, UM in 6, and BMG in 62 (staged BMG in 50 cases and DIGU in 12). CONCLUSIONS: The selected type of repair will depend on many factors, like residual healthy local skin and expertise. Safe techniques for repair of redo hypospadias after its 1st failure include TIPU, Mathieu, UM, OIF, and DIGU for distal varieties. After 2nd or 3rd repair DIGU, UM, and TIPU can be performed in distal types, while staged BMG can be applied for proximal ones.

Does local injection of long acting corticosteroid improve postoperative outcome of hypospadias repair? A randomized controlled trial.

PURPOSE: To assess the safety and efficacy of local corticosteroid injection during hypospadias repair. METHODS: Between May 2021 and March 2023 children less than 10 years who were admitted for hypospadias repair were divided by random allocation into two groups. We injected local corticosteroid 2 ml proximal to coronal sulcus in group A while in group B we didn't. All types of hypospadias were included in the study. We excluded patients older than 10 years and those with pre-existing complicated hypospadias (multiple fistulae and multiple surgeries), or bleeding diatheses. Pre-operative, intraoperative and postoperative variables were compared between the two groups. RESULTS: A total of 120 patients (60 in each group) were enrolled in the study. The mean ages and preoperative variables were not significantly different. The site of hypospadias and the type of surgery were comparable in both groups. (Table) There were no significant differences between both groups regarding average blood loss and operative time in each type of surgical repair. There was a significant higher incidence of intraoperative and postoperative penile oedema in group B (P-value < 0.001) while the incidence of skin discolouration was higher in group A. Postoperative complications, described as Clavian classification, were significantly higher in group B. The incidences of superficial skin infection, meatal stenosis, urethral fistula, and recurrence with the need for redo repair were significantly higher in group B (P-value: 0.002, 0.018, 0.032, and 0.001, respectively). CONCLUSION: Local corticosteroid injection during hypospadias repair minimize the penile oedema and decrease the incidence of postoperative functional and cosmetic complications.

Megameatus intact prepuce variant reconstruction: Long-term outcomes and comparison to post-circumcision hypospadias repair.

BACKGROUND: Megameatus intact prepuce (MIP) variant is considered a surgical challenge with associated high complication rates. It is usually diagnosed and corrected only after neonatal circumcision, which is discouraged in non-MIP hypospadias. OBJECTIVE: In order to determine whether the features of the MIP variant or the performance of a secondary reconstruction following circumcision comprise the cause of higher complication rates, we now compared the results of post-circumcision MIP hypospadias repair to the results of children who underwent repair of non-MIP hypospadias following neonatal circumcision. STUDY DESIGN: Reoperation rates of children operated for hypospadias repair following neonatal circumcision between 1999 and 2020 were compared between those with MIP and those with classic non-MIP hypospadias. RESULTS: In total, 139 patients who had undergone neonatal circumcision underwent surgical reconstruction at a mean age of 13 months. Sixty-nine had classic hypospadias and 70 had the MIP variant. The median follow-up was 10 years (interquartile range 6,13). The classic group had a higher rate of meatal location below the corona compared to the MIP variant group (53 % vs. 28 %, respectively, p = 0.002). The reoperation rate was comparable for the two groups (32 % vs. 27 %, p = 0.58, Table). Univariate analysis for the MIP hypospadias group showed no association between reoperation and the initial patient characteristics, while a higher probability of reoperation was demonstrated in the presence of ventral curvature (odds ratio 3.5, p = 0.02), and a higher grade of hypospadias (odds ratio 3.3, p = 0.03 for meatal location lower than the coronal sulcus) in the non-MIP group. DISCUSSION: The limitations of our work include its retrospective design wherein the patients' characteristics, including classification as MIP vs. non-MIP, are derived from medical records. More patients in the non-MIP group were documented to have penile curvature. The non-MIP group was composed of more patients with meatal location under the coronal sulcus, a factor which may increase the rates for reoperation in that group. Still, with the comparison of the largest reported cohort of circumcised MIP with circumcised non-MIP patients together with an extended follow-up period, we believe that we present strong evidence of the possible role of previous circumcision in the surgical challenge of reconstructing MIP hypospadias. CONCLUSIONS: Reoperation rates in MIP hypospadias are high but similar to those of classic hypospadias, both following circumcision, suggesting that circumcision, rather than the unique features of the variant, is the cause for complications.

Risk factors and timing of complication presentation following primary hypospadias repair in adolescents.

OBJECTIVES: To evaluate the risk factors for postoperative complications in adolescents who undergo primary hypospadias repair and determine the time required for complication detection. METHODS: Our study included patients classified as Tanner stages three to five who underwent primary hypospadias repairs at our hospital from January 2015 to August 2022. The patients' baseline information, clinical characteristics, postoperative complications, and time to complication detection were collected. Cox regression analysis, ROC curves, Kaplan-Meier survival analyses, and the Mann-Whitney U test were used. RESULTS: The study comprised 143 patients, with a median age of 12.58 years. Postoperative complications were experienced by 66 patients. The length of the urethral defect was identified as an independent risk factor for postoperative complications. The ROC curve analysis identified 3 cm as the optimal cutoff value for the length of the urethral defect. The median time to complication detection was 30.5 days (IQR 23 to 209.25). 89.4% of the complications were identified within the first year. Patients with a urethral defect of <3 cm experienced a significantly longer time for the detection of urethral fistula compared to those with a urethral defect of ≥3 cm (p = 0.047). CONCLUSIONS: Our data indicate that adolescents with a urethral defect ≥3 cm have a higher risk of postoperative complications. Although most complications were identified within the first year, conducting long-term follow-ups for adolescents is recommended to identify potential subsequent complications that may arise from persistent urethral alterations.

Transperineal anastomotic posterior urethroplasty with bulbocavernosus flap and fibrin sealant in the complicated posterior urethral stricture reconstruction: a retrospective cohort study.

BACKGROUND: Management of complicated posterior urethral stricture is challenging. Modified transperineal anastomotic urethroplasty (TAU) with bulbocavernosus flap interposition and human fibrin sealant provides another treatment option. The authors aimed to evaluate whether this technique could improve the success rate in the complicated posterior urethral stricture reconstruction in this study. MATERIALS AND METHODS: Between 2016 and 2019, 48 patients underwent either conventional or modified TAU. The criteria for success included both the absence of clinical symptoms and no need for further surgical intervention during follow-up. RESULTS: Twelve patients underwent the modified TAU (group A) using bulbocavernosus flap interposition and human fibrin sealant. Thirty-six patients underwent the traditional end-to-end anastomotic urethroplasty (group B). Follow-up was 24.3-57.2 months. The patients in group A had a higher surgery success rate compared to the patients in group B (91.7 vs. 63.9%, P =0.067), with a quasi-significant result. Besides, no postoperative complications were observed in group A, while two individuals in group B had urinary incontinence, but the difference was not significant (0 vs. 5.6%, P =0.404). CONCLUSION: Based on the preliminary results, modified TAU with bulbocavernosus flap interposition and human fibrin sealant is a safe and feasible technique for complicated posterior urethral stricture reconstruction.

Early Postoperative Complications of One-Stage Substitution Urethroplasty with Oral Mucosa Graft: A Monocentric Retrospective Study.

INTRODUCTION: We report early postoperative complications (PCs) (≤90 days) of one-stage oral mucosa graft (OMG) urethroplasty in treatment of acquired anterior urethral strictures. MATERIAL AND METHODS: In this study, we evaluated 530 males who underwent one-stage substitution urethroplasty (SU) between September 1996 and October 2020. Medical records were reviewed to identify and classify early PCs based on the Clavien-Dindo classification (CDC). We subdivided the PCs into three groups with different kinds of complications which allowed us a more detailed analysis concerning general surgical complications (GSCs), donor site morbidity (DSM) and complications specific for free graft urethroplasty (CSUs). The influence of patient demographics, stricture characteristics and operative procedure on the occurrence of PCs was analysed. RESULTS: Early (90-day) PCs occurred in 90 (16.98%) patients, whereas only 19 patients (3.58%) experienced serious events (CDC grades III and IV). Early complications include 4.5% GSCs, 1.7% DSM and 10.8% CSUs. Only stricture length turned out to be an independent statistically significant risk factor for the occurrence of early PCs. There was a trend towards a higher rate of complications in patients with ASA III compared to ASA I. CONCLUSION: The incidence of severe early complications in patients undergoing one-stage SU with OMG is low.

Affirming Long-Term Outcomes After Contemporary Urethroplasty: The Adverse Impact of Increasing Stricture Length, Lichen Sclerosus, Radiation, and Infectious Strictures.

PURPOSE: There is a paucity of reported long-term outcomes after contemporary urethroplasty. Our objective is to determine the long-term success of modern urethroplasty and identify factors associated with stricture recurrence in this context. MATERIALS AND METHODS: Patients undergoing urethroplasty from July 2003 to May 2013 with at least 100 months of follow-up were identified. Long-term outcomes including stricture recurrence and patient satisfaction were evaluated by review of regional/provincial electronic records and telephone interview. Urethroplasty failure was defined as a recurrent stricture (<16F) confirmed on cystoscopy. Cox regression was used to evaluate variables associated with long-term stricture recurrence. RESULTS: A total of 733 patients were identified with ≥ 100 months follow-up. Median patient age was 45 years, stricture length was 4.7 cm, and 85.8% failed prior endoscopic treatment. At a median follow-up of 12.3 years, 89 recurrences were observed. Cumulative incidence of stricture recurrence was 6%, 10%, and 12% after 1, 5, and 10 years, respectively. From a patient-reported perspective, 89% of patients reported being satisfied with the outcome of surgery. On multivariable analyses, increasing stricture length (HR 1.1, 95% CI 1.05-1.15; P < .001) and stricture etiology (P < .001), in particular lichen sclerosus (HR 4.46, 95% CI 2.25-9.53), radiation (HR 4.25, 95% CI 1.65-10.9), and infectious strictures (HR 5.27, 95% CI 2.03-13.7), were independently associated with stricture recurrence. CONCLUSIONS: This study affirms the widely held belief that modern urethroplasty provides high long-term patency and patient-reported satisfaction. Patients with longer strictures as well as those with lichen sclerosus, radiation, and infectious etiologies have a higher hazard of stricture recurrence in the long term.

Risk-Factor Analysis and Prediction-Model Construction of Urethral Stricture after Hypospadias Surgery in Children: A Single-Centre Retrospective Study.

OBJECTIVE: This study aimed to explore the incidence of postoperative urethral stricture in children after hypospadias surgery, analyse its risk factors, and construct a prediction model. METHODS: We retrospectively analysed the clinical data of 402 children with hypospadias surgery in Hunan Children's Hospital from January 2022 to January 2023. To explore the risk factors of urethral stricture after hypospadias surgery in children, the incidence of postoperative urethral stricture in children was statistically analysed, and univariate and multivariate logistic regression analyses were adopted. A prediction model was established, and the prediction efficiency of the model was examined using a receiver operating characteristic curve. RESULTS: The incidence of postoperative urethral stricture in children after hypospadias surgery was 9.20% (37/402). On this basis, the children were divided into stricture group (SG, n = 37) and normal group (NG, n = 365). Both groups had overt differences in disease classification, urinary tract infection, indwelling-catheter time, and surgical methods (p < 0.05). Logistic regression analysis showed that urinary tract infection, surgical methods, and long indwelling-catheter time were the risk factors (p < 0.001). The prediction model constructed based on the above results had certain prediction efficiency. CONCLUSIONS: More attention should be paid to children with urinary tract infection, high-risk surgery, and long indwelling-catheter time after hypospadias surgery. Our prediction model can serve as an effective reference for evaluating the occurrence of postoperative urethral stricture.

Low risk of erectile dysfunction after nontransecting bulbar urethroplasty for urethral stricture: a systematic review and meta-analysis.

BACKGROUND: Sexual function after urethroplasty may be a concern for patients, but there are still some controversies regarding the consequences of nontransecting bulbar urethroplasty (ntBU) in terms of erectile dysfunction (ED). AIM: This meta-analysis aimed to compare the efficacy and safety of ntBU with that of transecting bulbar urethroplasty (tBU). METHODS: The PubMed, Web of Science, Cochrane, and Embase databases were searched and reviewed up to October 31, 2022. Quality evaluation was performed using the Newcastle-Ottawa scale system and Cochrane tools for the nonrandomized and randomized studies, respectively. Baseline characteristics, preoperative information, and postoperative outcomes were collected. OUTCOMES: Outcomes included success rate, ED, overall complication, and maximum urinary flow. RESULTS: Thirteen studies comprising 1683 patients met the inclusion criteria, with 596 and 1087 patients undergoing ntBU and tBU, respectively. The results revealed that compared with the tBU group, the patients who underwent ntBU had a significantly lower incidence of ED, while there were no significant differences in the other perioperative outcomes. In subgroup analysis, the nontransecting anastomotic urethroplasty group had a lower incidence of ED than excision and primary anastomosis, and other perioperative outcomes were similar between the 2 groups. CLINICAL IMPLICATIONS: The results of the study may help clinicians choose procedures that protect sexual function in the treatment of urethral stricture. STRENGTHS AND LIMITATIONS: The strength of this study is that it is, to our knowledge, the first meta-analysis to evaluate the efficacy and safety of ntBU. A limitation is that most of the included studies were retrospective cohort studies. CONCLUSION: ntBU preserves the high efficacy of its transecting counterpart while reducing postoperative ED.

Risk-Factor Analysis and Prediction-Model Constructionof Urethral Stricture after Hypospadias Surgery inChildren: A Single-Centre Retrospective Study

Objective: This study aimed to explore the incidence of postoperative urethral stricture in children after hypospadias surgery, analyse its risk factors, and construct a prediction model. Methods: We retrospectively analysed the clinical data of 402 children with hypospadias surgery in Hunan Children’s Hospital from January 2022 to January 2023. To explore the risk factors of urethral stricture after hypospadias surgery in children, the incidence of postoperative urethral stricture in children was statistically analysed, and univariate and multivariate logistic regression analyses were adopted. A prediction model was established, and the prediction efficiency of the model was examined using a receiver operating characteristic curve. Results: The incidence of postoperative urethral stricture in children after hypospadias surgery was 9.20% (37/402). On this basis, the children were divided into stricture group (SG, n = 37) and normal group (NG, n = 365). Both groups had overt differences in disease classification, urinary tract infection, indwelling-catheter time, and surgical methods (p < 0.05). Logistic regression analysis showed that urinary tract infection, surgical methods, and long indwelling-catheter time were the risk factors (p < 0.001). The prediction model constructed based on the above results had certain prediction efficiency. Conclusions: More attention should be paid to children with urinary tract infection, high-risk surgery, and long indwelling-catheter time after hypospadias surgery. Our prediction model can serve as an effective reference for evaluating the occurrence of postoperative urethral stricture (AU)

Risk factors for postoperative complications following one-stage proximal hypospadias repair involving the disconnection of the urethral plate: a retrospective study.

BACKGROUND: Children with hypospadias are at risk of serious physical and mental health problems, including abnormal urination, sexual dysfunction, and infertility. The sole available treatment is the surgical restoration of genital appearance and function. Proximal hypospadias (PH) correction is more challenging and carries a higher risk of complications than does distal hypospadias correction, with a higher likelihood of postoperative complications requiring additional surgery, resulting in considerable economic and psychological strain for families. Herein, we aimed to identify factors associated with complications following one-stage PH repair with urethral plate disconnection. METHODS: We retrospectively analyzed data from 236 children who underwent PH repair at our center between December 2020 and December 2022. We collected information on age, surgical procedure, length of the reconstructed urethra (LRU), glans width (GW), ventral curvature, surgical approach, preoperative androgen use, suture type, presence of prostatic utricle, body mass index, season of surgery, anesthesia type, low birth weight, preterm birth, follow-up period, and complications. Surgical complications included urethral fistulas, urethral diverticula, anastomotic strictures, urethral strictures, glans dehiscence, and penile curvature recurrences. The study population was divided into complication and no-complication groups, and univariate and multivariate analyses were conducted. RESULTS: Of the 236 patients with PH who had a median follow-up of 10.0 (8.0, 14.0) months, 79 were included (33.5%) in the complication group and 157 were included (66.5%) in the no-complication group. In the univariate analysis, age (P < 0.001), LRU (P < 0.001), degree of penile curvature (P = 0.049), and PH with prostatic utricle (P = 0.014) were significantly associated with complications after PH repair. In the multivariate logistic regression analysis, LRU (P<0.001, odds ratio [OR] = 3.396, 95% confidence interval [CI]: 2.229-5.174) and GW (P = 0.004, OR = 0.755, 95%CI: 0.625-0.912) were independent factors influencing postoperative complications. The optimal LRU threshold was 4.45 cm (area under the curve, 0.833; sensitivity, 0.873; specificity, 0.873; P<0.001, OR = 3.396, 95% CI: 2.229-5.174). CONCLUSIONS: LRU and GW are independent factors affecting PH complications. An LRU of < 4.45 cm and an increased GW can reduce the risk of complications.

Are there anatomical limiting factors to foreskin reconstruction at the time of single-stage hypospadias repair?

INTRODUCTION: Foreskin reconstruction (FR) at the time of primary hypospadias repair is a truly anatomically complete reconstruction of the hypospadic penis. We prospectively collected penile and preputial measurement of children undergoing single-stage hypospadias repair and FR with the aim to identify possible relations between penile and preputial anatomy and the likelihood to develop complications. MATERIALS AND METHODS: We prospectively studied children who underwent single stage hypospadias repair associated with FR from 2016 to 2019. We recorded intra-operative foreskin and penile measurements and post-operative outcomes. Logistic Regression analysis was performed to explore independent factors affecting urethroplasty and skin complications. Chi square test was used to compare outcomes in different groups based on ventral foreskin defect (VFD) width, Glans size, age at surgery and meatal location. RESULTS: From a total of 181 consecutive patients, 86 boys who underwent a single stage hypospadias repair combined with FR were included in the study. Patients were excluded because they were either lost at follow up (n = 10), required a 2-stage repair (n = 2), were circumcised at birth (n = 3) or parents requested a circumcision (n = 78); in 2 patients, a decision to perform circumcision was made intraoperatively due to aesthetic reasons (monk-hood deformity of the prepuce). Median age at surgery was 17 months. Mean glans width was 14.4 mm. Mean unstretched and stretched foreskin circumference were 29.5 mm and 40.9 mm, respectively. Mean VFD (the distance between the proximal insertion of the foreskin hood on either side of the midline at the level of the coronal sulcus) was 7.2 mm (Fig. 1). At median follow-up of 8 months (6-23), 9 complications were recorded (10.4%): foreskin dehiscence occurred in 1% (1/86), a foreskin fistula was noted in 4.6% (4/86), tight, non-retractile, foreskin in 1% (1/86); urethrocutaneous fistula in 2.3% (2/86) and complete dehiscence of the glans and foreskin in 1 (1.2%). Multiple logistic regression analysis demonstrated that none of the measurements obtained was an independent risk factor for developing urethroplasty or skin complications. There was no significant difference in complications between wide VFD (>7 mm) vs. narrow VFD (≤7 mm), large glans (>14 mm) vs. small glans (≤14 mm), age at surgery ≤24 months vs. > 24 month and meatal location distal (glanular, coronal, subcoronal and distal penile) vs. proximal (midpenile, proximal penile and penoscrotal). CONCLUSION: To the best of our knowledge, this is the first study reporting a prospective and objective assessment of the foreskin in the context of single stage hypospadias repair. Individual anatomical differences in preputial and penile anatomy do not seem to affect the likelihood of skin and urethroplasty complications. FR can, therefore, be offered to all boys undergoing primary single stage hypospadias repair . Further studies on larger numbers and external validation of these measurements is necessary.

Mucomucosal anastomotic non-transecting augmentation (MANTA) urethroplasty: a ventral modification for obliterative strictures.

OBJECTIVES: To present a surgical modification for the repair of bulbar urethral strictures containing short, highly obliterative segments and report on long-term objective and patient-reported outcomes. PATIENTS AND METHODS: We considered patients undergoing bulbar buccal mucosal graft urethroplasty (BMGU) between July 2016 and December 2019. Eligibility criteria for mucomucosal anastomotic non-transecting augmentation (MANTA) urethroplasty were strictures of ≥2 cm with an obliterative segment of ≤1.5 cm. The stricture is approached ventrally to avoid extensive dissection and mobilisation. Dorsally, the scar is superficially excised and the spongiosum is left intact. Dorsal mucomucosal anastomosis is complemented by ventral onlay graft. Perioperative characteristics were prospectively collected including uroflowmetry data and validated patient-reported outcome measures on voiding, erectile, and continence function. We evaluated functional follow-up, incorporating patient-reported (lower urinary tract symptoms [LUTS] score) and functional success. Recurrence was defined as need of re-treatment. RESULTS: Of 641 men treated with anterior BMGU, 54 (8.4%) underwent MANTA urethroplasty. Overall, 26 (48%) and 45 (83%) had a history of dilatation and urethrotomy, respectively, and 14 (26%) were redo cases. Location was bulbar in 38 (70%) and penobulbar in 16 patients (30%), and the mean (SD) graft length was 4.5 (1.4) cm. At a median (interquartile range) follow-up of 41 (27-53) months, the functional success rate was 93%. Whereas the median LUTS score significantly improved from baseline to postoperatively (13 vs 3.5; P < 0.001), there was no change in erectile function (median International Index of Erectile Function - erectile function domain score 27 vs 24) or urinary continence (median International Consultation on Incontinence Questionnaire - Urinary Incontinence Short Form sum score 0 vs 0; all P ≥ 0.4). All patients were 'satisfied' (27%) or 'very satisfied' (73%) with the outcome of their operation. CONCLUSION: With excellent long-term objective and patient-reported outcomes, MANTA urethroplasty adds to the armamentarium for long bulbar strictures with a short obliterative segment.
