RESUMO

OBJECTIVES: Redo surgery for pelvic fracture urethral distraction defects (PFUDDs) is still a challenge. the long urethral defect makes it difficult while the high tension increase the recurrence rate. Although certain ancillary maneuvers can relieve tension, there is no consensus or guidelines for the prediction/planning of the selection. In this study, we present our experience with developing an intraoperative guidance system to achieve tension-free urethral anastomosis. PATIENTS AND METHODS: A total of 91 recurrent PFUDD patients managed at our center between 2020 and 2022 were retrospectively analyzed. The patients underwent scar removing and urethral anastomosis. For the long defect and high-tension cases, 6 kinds of tension-relieving maneuvers were used respectively during the process of urethral anastomosis. Preoperative assessment of the urethrogram was done before surgery, while biaxial (vertical and horizontal) defect measurements were performed intraoperatively. The patients were followed-up for 12 months (8.9 ± 4.2), furthermore, recurrence and complications were analyzed. RESULTS: The overall success rate was 86.81%. The mean defect in urethrogram was 2.9 ± 1.1 cm. 27 simple anastomosis was performed when the vertical plus horizontal defect was less than 2 cm with 11.11% recurrence. 24 cavernous septum splittings were performed when the horizontal defect was greater than 2 cm with 8.33% recurrence. 21 inferior pubectomies were performed when the horizontal defect was greater than 3 cm with 19.05% recurrence. 15 ancillary distal urethra manipulations (fully distal urethral mobilization, urethral suspension and corpus cavernosa folding) were performed when the vertical defect was 3 to 4 cm with 13.33 recurrence. 4 reroutings were performed when the vertical defect was greater than 4 cm with 25.00% recurrence. CONCLUSIONS: Ancillary maneuvers are effective for reducing tension in redo urethral anastomosis. Measurement of divergent vertical and horizontal urethral defects could guide the selection of ancillary maneuvers. Combined tension-relieving maneuvers is recommended according to the defect direction and length to achieve a tension-free anastomosis.

RESUMO

INTRODUCTION: Urethral stricture is a common, albeit complex, condition that predominantly affects men. The aim of this study was to translate, culturally adapt, and validate the Patient-Reported Outcome Measure questionnaire for patients undergoing urethroplasty (USS-PROM) into Brazilian Portuguese using validated psychometric criteria. MATERIALS AND METHODS: The process involved translating and culturally adapting the original USS-PROM into Brazilian Portuguese (USS-PROMbr), synthesizing, back-translating, cross-culturally adapting, and analyzing the pre-final version with experts from our committee. This pre-version was administered to 10 patients who had undergone urethroplasty by the Reconstructive Urology team at the Hospital de Clínicas de Porto Alegre for face validation, linguistic, and semantic adjustments, resulting in the final USS-PROMbr version. Subsequently, well-established psychometric criteria, including content validity, internal consistency, and test-retest reproducibility, were assessed after administering the questionnaire to a total of 56 patients, with 50 of them responding to the test and retest. RESULTS: Evaluation of the pre-final version identified 15 questions as clear, and only one question was considered somewhat unclear necessitating modifications based on patient suggestions and subsequent reassessment by the research team. Psychometric criteria demonstrated good content validity, with a content validity index exceeding 0.80 for all questions; good internal consistency, Cronbach's alpha of 0.77, ranging from 0.70 to 0.78 with the exclusion of any item, and item-total correlations ranging from 0.33 to 0.67. The test-retest intraclass correlation coefficient was 0.74 for the lower urinary tract symptoms construct (Q1-Q6). CONCLUSION: The USS-PROMbr demonstrated acceptable cross-cultural adaptation and psychometric properties, making it a valid and useful tool for evaluating patients undergoing urethroplasty.

RESUMO

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.

RESUMO

OBJECTIVE: A retrospective study was performed to analyse the influencing factors of stricture recurrence after urethroplasty and to establish a predictive nomogram model. METHODS: The clinical data of patients who underwent urethroplasty in our hospital from January 2021 to June 2023 were retrospectively analysed. Depending on whether stenosis occurs six months after surgery, the patients were divided into recurrence and nonrecurrence groups. Logistic regression analysis was performed on the indicators with statistically significant differences between the two groups in single factor analysis to analyse the influencing factors of postoperative recurrence risk of stricture. X64.4.1.3 version R language and external source packages were used to build the nomogram model. The nomogram was internally validated through 10-fold cross-validation, and C-index was calculated. The area under the curve (AUC) of the receiver operating characteristic curve was employed to evaluate the results of the internal validation. RESULTS: Amongst 105 patients who underwent urethroplasty in our hospital, 15 patients with recurrence were included in the recurrence group, and 90 patients without recurrence were included in the nonrecurrence group. The length of stricture segment, history of urethroplasty and smoking history within 3 months before surgery were risk factors for stricture recurrence, with odds ratio (OR) values of 1.874 (95% CI: 1.103-5.725), 1.670 (95% CI: 1.105-2.904) and 1.740 (95% CI: 1.456-5.785), respectively. The constructed nomogram obtained an average AUC of 0.842 and an average C-index of 0.794, calculated after 200 times of 10-fold cross-validation. CONCLUSIONS: From the data of this study, it can be deduced that the influencing factors of stricture recurrence after urethroplasty include the length of stricture segment, history of urethroplasty and smoking history of 3 months before surgery. Using the above factors as a basis to construct a predictive nomogram model is helpful to screen high-risk patients with recurrence of stricture after urethroplasty.

RESUMO

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.

RESUMO

PURPOSE: To compare the outcomes of patients undergoing robotic YV plasty for bladder neck contracture (BNC) vs. vesico-urethral anastomotic stricture (VUAS). METHODS: A retrospective study included male patients who underwent robotic YV plasty for BNC after endoscopic treatment of BPH or VUAS between August 2019 and March 2023 at a single academic center. The primary assessed was the patency rate at 1 month post-YV plasty and during the last follow-up visit. RESULTS: A total of 21 patients were analyzed, comprising 6 in the VUAS group and 15 in the BNC group. Patients with VUAS had significantly longer operative times (277.5 vs. 146.7 min; p = 0.008) and hospital stay (3.2 vs. 1.7 days; p = 0.03). Postoperative complications were more common in the VUAS group (66.7% vs. 26.7%; p = 0.14). All patients resumed spontaneous voiding postoperatively. Five patients (23.8%) who developed de novo stress urinary incontinence had already an AUS (n = 1) or required concomitant AUS implantation (n = 3), all of whom were in the VUAS group (83.3% vs. 0%; p < 0.0001). The proportion of patients improved was similar in both groups (PGII = 1 or 2: 83.3% vs. 80%; p = 0.31). Stricture recurrence occurred in 9.5% of patients in the whole cohort, with no significant difference between the groups (p = 0.50). Long-term reoperation was required in three VUAS patients, showing a statistically significant difference between the groups (p = 0.05). CONCLUSION: Robotic YV plasty is feasible for both VUAS and BNC. While functional outcomes and stricture-free survival may be similar for both conditions, the perioperative outcomes were less favorable for VUAS patients.

RESUMO

Introducción El objetivo de este estudio es evaluar y comparar la función eréctil (FE) tras la uretroplastia por escisión y anastomosis primaria (UEAP) y la uretroplastia con injerto de mucosa oral (UIMO) en la estenosis de uretra bulbar. Métodos Se identificó retrospectivamente a los pacientes tratados mediante uretroplastia. Se determinaron como criterios de inclusión en el estudio la edad entre 18 y 70 años y ser sexualmente activo. Los criterios de exclusión fueron la disfunción eréctil grave preoperatoria, estenosis distinta de la uretra bulbar, incompatibilidad psicosocial, estenosis uretral relacionada con fractura pélvica y tiempo de seguimiento inferior a un año. Como criterio de valoración primario, se utilizó el International Index of Erectile Function-5 (IIEF-5) para la comparación de la FE en el preoperatorio y en el 3.°, 6.° y 12.° mes tras la intervención quirúrgica. El criterio de valoración secundario fue el efecto de los datos demográficos, las características de la estenosis y del tratamiento sobre la FE. Resultados Tras aplicar los criterios de inclusión y exclusión, se identificó a 50 pacientes. De ellos, 30 fueron tratados mediante UEAP y 20 mediante UIMO. Al 3.er mes de la intervención, la FE mostró una disminución estadísticamente significativa en el grupo UEAP. En ambos grupos de pacientes se observó una mejoría de los efectos negativos postoperatorios sobre la EF en el 6.° mes, que recuperaron su nivel basal a los 12 meses. Conclusión Las técnicas UEAP y UIMO tienen un efecto similar sobre la FE a medio y largo plazo y ambas pueden utilizarse con seguridad y eficacia en el grupo de pacientes adecuado. (AU)


Introduction The aim of this study is to evaluate and compare erection function (EF) after excision and primary anastomosis urethroplasty (EPAU) and buccal mucosal graft urethroplasty (BMGU) in bulbar urethral stricture. Methods Patients who underwent urethroplasty were identified retrospectively. The criteria for inclusion in the study were determined as being over 18 years old and under 70 years old, being sexually active. Exclusion criteria are: preoperative severe erectile dysfunction, stricture outside the bulbar urethra, psychosocial incompatibility, urethral stricture related to pelvic fracture, follow-up time less than a year. As the primary endpoint, the International Index of Erectile Function-5 (IIEF-5) was determined as a comparison of EF in the preoperative and 3rd, 6th and 12th months after surgery. The secondary endpoint was the evaluation of the effects of demographic data, stricture and treatment characteristics on EF. Results Fifty patients were identified considering the inclusion/exclusion criteria. It was observed that there were 30 patients who underwent EPAU and 20 patients who underwent BMGU. At the third month after surgery, EF showed a statistically significant decrease in the EPAU group. In both patient groups, it was observed that the early negative effects after the operation in EF started to improve in the 6th month and returned to the baseline level by the first year. Conclusion EPAU and BMGU techniques have a similar effect on EF in the medium and long term. Both methods can be used safely and effectively in the appropriate patient group. (AU)

RESUMO

PURPOSE: Small intestinal submucosa (SIS) graft urethroplasty has been employed to decrease buccal mucosa morbidity and facilitate the procedure. The first published series had a short follow-up, inhomogeneous patient selection, and a lack of a control group. Our purpose is to report treatment outcomes at 13 years in a propensity score-matched cohort comparing bulbar urethroplasty with SIS (SISU) or buccal mucosa (BMU). METHODS: From our institutional database of 1132 bulbar urethroplasties, we used propensity score matching with the nearest-neighbor method without replacement to generate a study sample of 25 BMU and 25 SISU. Failure was defined as any treatment after urethroplasty. Survival analyses were used to analyze treatment failure occurrence with data censored at 156mo. RESULTS: Matching resulted in a complete correction of bias between the two samples except for the follow-up duration, which was slightly longer in the SIS group. The cumulative treatment success probability of BMU and SISU at 156mo was 83.4% and 68%, respectively. At multivariable Cox regression, SIS graft, previous urethrotomy, stricture length, and lower postoperative Qmax (within 2mo after catheter removal) were predictors of failure. Stricture length had a more remarkable effect in SISU, with estimated survival probabilities from the Cox model lower than 80% in strictures > = 3 cm. CONCLUSION: SIS has poorer outcomes compared to BM but may still be useful when BM grafting is not possible. The best candidates for SISU, with similar success to BMU, are patients with strictures shorter than 3 cm, preferably without a history of DVIU.

RESUMO

Urethral stricture caused by various reasons has threatened the quality of life of patients for decades. Traditional reconstruction methods, especially for long-segment injuries, have shown poor outcomes in treating urethral strictures. Tissue engineering for urethral regeneration is an emerging concept in which special designed scaffolds and seed cells are used to promote local urethral regeneration. The scaffolds, seed cells, various factors and the host interact with each other and form the regenerative microenvironment. Among the various interactions involved, vascularization and fibrosis are the most important biological processes during urethral regeneration. Mesenchymal stem cells and induced pluripotent stem cells play special roles in stricture repair and facilitate long-segment urethral regeneration, but they may also induce carcinogenesis and genomic instability during reconstruction. Nevertheless, current technologies, such as genetic engineering, molecular imaging, and exosome extraction, provide us with opportunities to manage seed cell-related regenerative risks. In this review, we described the interactions among seed cells, scaffolds, factors and the host within the regenerative microenvironment, which may help in determining the exact molecular mechanisms involved in urethral stricture regeneration and promoting clinical trials and the application of urethral tissue engineering in patients suffering from urethral stricture.

RESUMO

OBJECTIVE: To assess the impact of posterior urethral stenosis or defect on outcomes following rectourethral fistula (RUF) repair, we present a cohort of 23 men who underwent posterior urethroplasty concurrent with RUF repair. METHODS: We identified 130 men who underwent RUF repair at our institution between 2003 and 2021. Of these, 23 (18%) underwent simultaneous posterior urethroplasty. Fifteen men received prior radiation for prostate cancer. Of the 8 men who were not radiated, 4 had a history of radical prostatectomy, 2 pelvic trauma, and 3 inflammatory bowel disease. All 23 men underwent fecal diversion prior to surgery (median, 6 months preoperatively), and 20 men suprapubic catheter placement (median, 5.5 months preoperatively). RESULTS: RUF repair was performed via perineal approach in 22 cases (96%) and prone Kraske position in 1 (4%). Intraoperatively, 20 men (87%) had urethral stenosis, and 3 (13%) had significant urethral defects due to cavitation and tissue loss. There was stenosis/stricture involving the prostatomembranous urethra in 18 cases (78%) and vesicourethral anastomosis in 5 (22%). Urethroplasty was performed with anastomotic repair in 18 patients (78%) and using a buccal mucosal graft in 5 (22%). Gracilis flap interposition was performed in 21 cases (91%). At a median follow-up of 55.7 months (interquartile range (IQR), 23-82 months), 20 men (87%) had successful RUF closure, with 3 patients experiencing RUF recurrence requiring further surgery. Fourteen men (61%) reported postoperative urinary incontinence, with 7 (30%) ultimately undergoing artificial urinary sphincter placement. There were no isolated stricture recurrences requiring instrumentation. CONCLUSION: Posterior urethral stenosis associated with RUF complicates an already challenging problem. However, most of these patients can be successfully treated concurrent with RUF repair. This series demonstrates that patients with RUF should not be ruled out for restorative reconstructive surgery based on the presence of posterior urethral stenosis or defect.

RESUMO

OBJECTIVE: To evaluate the outcomes of ventral onlay buccal mucosal graft urethroplasty (VOBMGU) in bulbomembranous urethral strictures after transurethral resection of the prostate. METHODS: After approval of the institutional ethical committee, we retrospectively examined the database of patients diagnosed with post-TURP urethral stricture (PTS) and treated by VOBMGU from January 2020 to January 2022. The patients were evaluated by retrograde urethrogram and voiding cystourethrogram. Follow-up evaluation included assessment of lower urinary tract symptoms, physical examination, uroflowmetry (Q-max and International Prostate Symptom Score) 3, 6, and 12months of follow-up. RESULTS: A total of 30 patients underwent VOBMGU for bulbomembranous PTS were included. The median age of the patients was 63.5 (11.25). The median stricture length was 3.5 (1.5) cm. During follow-up, the mean Q-max significantly increased to 21.1 ± 5.5 mL/s (P < .0001), 20.1 ± 5.4 mL/s (P < .001), and 19.1 ± 5.3 mL/s (P < .003) at 3, 6, and 12months, respectively. IPSS significantly decreased to 8.93 ± 6.37 at the 12-month follow-up mark (P < .0001). Three patients developed stricture recurrence and two patients developed postoperative urinary incontinence. CONCLUSION: VOBMGU in cases of bulbomembranous urethral PTS offered excellent functional outcomes with low stricture recurrence and minimal risk of incontinence. Further prospective studies are warranted to confirm the results.

RESUMO

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.

RESUMO

OBJECTIVE: The use of minimally invasive endoluminal treatment for urethral strictures has been a subject for debate for several decades. The aim of this study was to review and discuss the safety, efficacy and factors influencing the clinical application of balloon dilation for the treatment of male urethral strictures. DESIGN: Systematic review and meta-analysis. DATA SOURCES: Embase, Medline, Web of Science, Cochrane Library and Scopus were searched for publications published before 17 July 2022. STUDY SELECTION: Two independent researchers screened and assessed the results, and all clinical studies on balloon dilation for the treatment of urethral strictures in men were included. DATA EXTRACTION AND SYNTHESIS: The success rate, rate of adverse events, International Prostate Symptom Scores, maximum uroflow (Qmax) and postvoid residual urine volume were the main outcomes. Stata V.14.0 was used for statistical analysis. RESULTS: Fifteen studies with 715 patients were ultimately included in this systematic review. The pooled results of eight studies showed that the reported success rate of simple balloon dilation for male urethral strictures was 67.07% (95% confidence interval [CI]: 55.92% to 77.36%). The maximum urinary flow rate at 3 months (risk ratio [RR]= 2.6510, 95% CI: 1.0681 to 4.2338, p<0.01) and the maximum urinary flow rate at 1 year (RR= 1.6637, 95% CI: 1.1837 to 2.1437, p<0.05) were significantly different after dilation. There is insufficient evidence to suggest that balloon dilation is superior to optical internal urethrotomy or direct visual internal urethrotomy (DVIU) (RR= 1.4754, 95% CI: 0.7306 to 2.9793, p=0.278). CONCLUSION: Balloon dilation may be an intermediate step before urethroplasty and is a promising alternative therapy to simple dilation and DVIU. The balloon is a promising drug delivery tool, and paclitaxel drug-coated balloon dilation is effective in reducing retreatment rates in patients with recurrent anterior urethral strictures. The aetiology, location, length, previous treatment of urethral stricture may be associated with the efficacy of balloon dilation. PROSPERO REGISTRATION NUMBER: CRD42022334403.

RESUMO

PURPOSE: The treatment of urethral stenosis after a combination of prostatectomy and radiation therapy for prostate cancer is understudied. We evaluate the clinical and patient-related outcomes after dorsal onlay buccal mucosal graft urethroplasty (D-BMGU) in men who underwent prostatectomy and radiation therapy. MATERIALS AND METHODS: A multi-institutional, retrospective review of men with vesicourethral anastomotic stenosis or bulbomembranous urethral stricture disease after radical prostatectomy and radiation therapy from 8 institutions between 2013 to 2021 was performed. The primary outcomes were stenosis recurrence and development of de novo stress urinary incontinence. Secondary outcomes were surgical complications, changes in voiding, and patient-reported satisfaction. RESULTS: Forty-five men were treated with D-BMGU for stenosis following prostatectomy and radiation. There was a total of 7 recurrences. Median follow-up in patients without recurrence was 21 months (IQR 12-24). There were no incidents of de novo incontinence, 28 patients were incontinent pre- and postoperatively, and of the 6 patients managed with suprapubic catheter preoperatively, 4 were continent after repair. Following repair, men had significant improvement in postvoid residual, uroflow, International Prostate Symptom Score, and International Prostate Symptom Score quality-of-life domain. Overall satisfaction was +2 or better in 86.6% of men on the Global Response Assessment. CONCLUSIONS: D-BMGU is a safe, feasible, and effective technique in patients with urethral stenosis after a combination of prostatectomy and radiation therapy. Although our findings suggest this technique may result in lower rates of de novo urinary incontinence compared to conventional urethral transection and excision techniques, head-to-head comparisons are needed.

RESUMO

OBJECTIVE: Describe the management of incontinence with several therapies, culminating with the apparently successful treatment utilizing artificial sphincter placement following an inadvertent prostatectomy. ANIMAL: 5-month-old 7.5-kg male neutered Miniature Schnauzer. CLINICAL PRESENTATION, PROGRESSION, AND PROCEDURES: The patient was referred for dysuria and persistent stranguria following an iatrogenic total prostatectomy and urethrectomy. An extra pelvic urethral anastomosis was performed, followed by hospitalization for 2 weeks with a urinary catheter. The patient was further investigated for persistent stranguria, and a contrast urethrogram revealed a urethral stricture at the anastomosis site, which was treated with fluoroscopic balloon dilation. The stranguria resolved, but an acute nocturnal grade 3 passive urinary incontinence occurred, which was nonresponsive to medical management of phenylpropanolamine hydrochloride and estriol. An artificial urethral sphincter was placed, leading to continence after 5 top-ups to a total volume of 0.9 mL. The patient remained continent for 5.5 weeks before abrupt incontinence recurred, which was resolved by another 0.1-mL top-up. No further signs of incontinence occurred in the 11 months following. TREATMENT AND OUTCOME: The placement of an artificial urethral sphincter successfully managed urinary incontinence in this patient. Continence was achieved with no significant complications other than a transient loss of continence. Long-term follow-up 14 months after sphincter placement revealed that the patient had remained continent since the final sphincter top-up. The owner reported a significant improvement in the patient's quality of life following successful incontinence management. CLINICAL RELEVANCE: This case highlighted the benefits of placing an artificial urethral sphincter in managing urinary incontinence after select cases of prostatectomy in dogs that are unresponsive to medical management.
