RESUMO
BACKGROUND: Bladder perforation (BP) is one of the important complications during transurethral resection of bladder tumour (TURBT). Additionally, multiple factors can contribute to BP. Here, we investigated the rates of BP, specifically in variant histology of bladder cancer (BC), and examined the clinical follow-up of relevant patients. METHODS: Of the 797 patients who underwent TURBT between 2015 and 2023, they were divided into two groups according to BP during the operation. Group 1 (n = 744) consisted of patients without BP, whereas Group 2 (n = 53) consisted of patients with BP. Demographic, operative, postoperative and follow-up data were investigated and analysed. Groups were examined in terms of causes of BP. Significance was set at p < 0.05. RESULTS: A significantly higher rate of BP was found in patients operated with bipolar energy (p = 0.027) than in their counterparts. In multivariable analysis, the presence of the obturator reflex during TURBT was significantly associated with an increased risk of BP (p < 0.001). We observed a statistically significant increase in the rate of BP in patients with a history of previous intravesical Bacillus Calmette-Guérin (BCG) therapy (p = 0.023). Variant histology was reported in 32 patients (4%). However, we could not find any statistically significant relationship between the development of BP and the variant histology of BC (p = 0.641). CONCLUSIONS: Multiple factors can affect BP during TURBT. Understanding the factors associated with BP is crucial for improving patient safety and outcomes. According to the results of the present study, the energy source, the presence of obturator reflex during TURBT and intravesical BCG therapy may increase BP. Nevertheless, the presence of variant histology was not significantly associated with BP.

A 70-year-old male came to our clinic with a high fever and left scrotal swelling. Following a diagnosis of left-side epididymitis, antibiotic treatment was started, though the swelling did not improve. Since an additional examination revealed an abscess in the left scrotum, scrotal incision and drainage were performed. Although the symptoms subsided, urine outflow from the incision was observed. The patient then noted that he had inserted a glass ball into the urethral meatus when he was about 30 years old. It was considered that an abscess and fistula had formed due to inflammation caused by the foreign body. Thus a transurethral surgical procedure was used for crushing and removal. The fistula disappeared within three months after the operation and the patient has not been affected by dysuria since that time. Symptoms may appear several years following insertion of a foreign body into the urethra. To the best of our knowledge, the present case is the longest term of indwelling, approximately 40 years, following insertion of a foreign body reported in Japan.

Urethral injuries are rare among the pediatric population, and the majority occur after trauma. This is the case of an eight-year-old female with complete proximal urethral disruption and ruptured bladder neck without pelvic fracture after a motor vehicle crash. After the accident, her bladder neck was reapproximated and a suprapubic tube was placed. Three months later, she underwent reconstruction for a bladder neck closure and appendicovesicostomy. In managing these patients, focus should first be directed at achieving a safe means of urinary drainage, and next to repair the lower urinary tract to maximize continence and minimize complications.

Transanal total mesorectal excision (taTME) has improved the laparoscopic dissection for rectal cancer in the narrow pelvis. Although taTME has more clinical benefits than laparoscopic surgery, such as a better view of the distal rectum and direct determination of distal resection margin, an intraoperative urethral injury could occur in excision ta-TME. This study aimed to determine the feasibility and efficacy of the ta-TME with IRIS U kit surgery. This retrospective study enrolled 10 rectal cancer patients who underwent a taTME with an IRIS U kit. The study endpoints were the safety of access (intra- or postoperative morbidity). The detectability of the IRIS U kit catheter was investigated by using a laparoscope-ICG fluorescence camera system. Their mean age was 71.4±6.4 (58-78) years; 80 were men, and 2 were women. The mean operative time was 534.6 ± 94.5 min. The coloanal anastomosis was performed in 80%, and 20% underwent abdominal peritoneal resection. Two patients encountered postoperative complications graded as Clavien-Dindo grade 2. The transanal approach with IRIS U kit assistance is feasible, safe for patients with lower rectal cancer, and may prevent intraoperative urethral injury.

OBJECTIVES: To retrospectively investigate and analyze the characteristics of male bulbar urethral strictures or occlusions resulting from straddle injuries caused by falling from heights and riding activities. METHODS: The study included 56 patients with a history of straddle injury, who were divided into two groups: the falling group (n = 29) and the riding group (n = 27). All patients underwent urethroscopy and X-ray urethrography, followed by urethrotomy and anastomotic procedure. Both urethral and suprapubic catheters were retained for one month postoperatively. Subsequent follow-up assessments were conducted within one month to one year after surgery. RESULTS: The clinical data of two groups were analyzed. The average ages were 40.1 ± 11.2 (falling group, aged 18-59) and 26.8 ± 4.4 (riding group, aged 19-35), P < 0.05. In the falling group, 21 cases (72.4%) had offspring, while in the riding group, only 3 cases (11.1%) had offspring, P < 0.05. The stricture segments in the falling group were predominantly located in the proximal part of the bulbar region (89.7%), whereas in the riding group they mainly found in the distal part (96.3%), P < 0.05. In terms of urethrography results, the average lengths of stricture segments were measured as 17.6 ± 2.8 mm and 15.5 ± 4.6 mm respectively, P < 0.05. During surgery, the average lengths of stricture segments were recorded as 19.0 ± 2.5 mm and 17.4 ± 6.1 mm, P > 0.05. In the falling group, 20 cases (69.0%) involved bulbocavernosus muscle injury, P < 0.05. In the riding group, 5 cases (18.5%) involved corpus cavernosum injury, P < 0.05. After one month of the operation, all cases were able to pass through the 16Fr urethroscope without any apparent urethral strictures or complications observed in urethrography results. The maximum urinary flow rate for all cases exceeded 15 ml/s. Two months and one year after the operation, all cases experienced smooth urinary flow and ejaculation without any disorders reported. 3 cases (10.3%) in the falling group and 7 cases (25.9%) in the riding group complained of urethral stretching pain during erection, P > 0.05. CONCLUSIONS: Male bulbar urethral strictures or occlusions resulting from straddle injuries associated with falling from heights and riding activities exhibit distinct characteristics, necessitating the development of a comprehensive surgical plan tailored to the specific features of each condition and the diverse age groups affected.

INTRODUCTION: Pelvic fracture urethral injury (PFUI) is more severe in younger individuals. The adolescent group is prone to protracted morbidity due to severity of the injury and its impact on lifestyle. Hence, treatment options and data on outcomes are crucial in planning management. The adolescents are a subgroup in several series of PFUI, but literature exclusively studying this group is sparse. MATERIALS & METHODS: A retrospective review of all adolescents (aged between 10 and 19 years as defined by WHO) who underwent surgical repair for PFUI between January 2005 and December 2019 was conducted. Success was defined as a bell-shaped urine flow curve and Qmax of >15 ml/s, no evidence of re-stricture (on cystoscopy/MCU), and no re-intervention. Measurements of the length of the urethral defect and bulbar urethra were done using a digital scale by the radiologist from micturating cystourethrogram (MCU). The Gapometry/Urethrometry (GU) index was calculated as the ratio of the length of the urethral defect to that of the bulbar urethra. Data was analysed using SPSS software version 20.0 and Stata Version 16. The primary outcome was the success of anastomotic urethroplasty. Secondary outcomes were evaluating factors predicting operative complexity (simple perineal versus elaborate perineal approach). RESULTS: We studied 22 patients, out of which 8 were referred following prior failed intervention elsewhere. The mean age was 16.5 + 2.7 years. All the patients were treated using a perineal approach with an overall success rate of 90.9%. Two patients had a failure and were managed with Endoscopic Internal Urethrotomy (EIU), and urethral dilatation. The median follow-up was 24 months. All 8 patients with prior failed interventions had a successful outcome. Twelve patients required inferior pubectomy (elaborate perineal approach). The median length of the urethral defect (2.3 cm IQR- 1.45,3.30 vs. 1 cm, IQR-0.65, 1.6) and the mean GU index (0.45 ± 0.18 cm vs. 0.25 cm ± 0.12 cm) were significantly higher in those who required an elaborate perineal approach. CONCLUSIONS: The perineal approach for surgical repair (anastomotic urethroplasty) of pelvic fracture urethral injury has a favourable success rate of 90.9% in adolescents. Re-do anastomotic urethroplasty for prior failed repairs also had a high success rate of 100%. Cases requiring an elaborate perineal approach were associated with a significantly higher Gapometry/Urethrometry Index (>0.45) and length of the urethral defect (>2.3 cm). This information may assist in patient counselling and preparation for additional steps during repair.

PURPOSE: To establish a psychometric validated pelvic fracture-urethral injury postoperative erectile function patient reported outcome measure (PFUI pEF PROM). We also aim to explore PFUI patients' potential classification and suitable postoperative erectile function assessment pattern. METHODS: A total of 93 PFUI patients who treated by excision and primary anastomotic (EPA) urethroplasty from January 2020 to August 2022 were enrolled to this study. Patients who had intercourse completed the IIEF-5, those who had sexual stimulation other than intercourse finished PFUI pEF PROM, and those who performed both completed the IIEF-5, and PFUI pEF PROM. Erection Hardness Score (EHS) was completed by all patients. This PROM was performed psychometric validation and used to find PFUI patients potential classification through latent class analysis. Then, we determined the cut-off value though receiver-operating characteristic (ROC) curve and performed univariate analysis subgroups feature. RESULTS: The PFUI pEF PROM demonstrated high reliability and validity with a Cronbach's alpha of 0.928. It correlated significantly with IIEF-5 (r = 0.550, p < 0.001) and EHS (r = 0.909, p < 0.001). The latent class analysis identified three patient subgroups, with 14.5 as the subgroup cut-off value. Urethral stricture length, IIEF-5, and EHS score were identified as influence factors for maximal erection potential. An assessment pattern combining IIEF-5, EHS, and the PFUI pEF PROM covered 92.5% of patients. CONCLUSION: This PROM effectively addresses the current limitation in assessing erectile function in PFUI patients. This study provides a promising tool for stratified assessment, prediction erection recovery, and treatment guidance in the PFUI Erectile dysfunction field.

INTRODUCTION: Male urethral injuries are uncommon, and the ideal timing of the definitive treatment remains controversial. This study aimed to compare the outcomes of early and delayed interventions (1 month or more after the injury) for male urethral injuries. PATIENT AND METHODS: We conducted a retrospective review of the medical records of 67 male patients with urethral injuries treated at our institution between 2011 and 2020. We examined patient age, injury severity score (ISS), abbreviated injury scale, mechanism, location and severity of injury, presence of pelvic fractures, surgical interventions, timing of treatment, and complications. We analysed factors associated with urinary complications based on the location of urethral injury. Additionally, we performed a subset analysis of patients with severe injuries (ISS≥16) to assess the impact of delayed surgery. RESULTS: Overall, 47 %, 37 %, and 27 % of patients in the delayed treatment group (N = 30) had urethral stricture (US), erectile dysfunction (ED), and/or urinary incontinence (UI). These rates were greater than the 22 % US, 3 % ED, and 11 % UI rates in the early treatment group (N = 37). The subgroup analysis revealed that patients with anterior urethral injury (AUI) who underwent delayed treatment (N = 18) tended to be more severely injured (ISS, 19 vs 9, p = 0.003) and exhibited higher rates of US (44% vs 21 %, p = 0.193) and ED (39% vs 0 %, p = 0.002) than those who received early treatment (N = 24). In the case of posterior urethral injury (PUI), the delayed treatment group (N = 13) had higher rates of US (50% vs 23 %, p = 0.326), ED (33% vs 8 %, p = 0.272), and UI (42% vs 0 %, p = 0.030) than the early treatment group. Regarding study limitations, more than 45 % of the enrolled patients were severely injured (ISS≥16), which may have potentially influenced the timing of urethral injury repair. CONCLUSIONS: The treatment of male urethral injuries may be delayed due to concurrent polytrauma and other associated injuries. However, delayed treatment is associated with higher rates of urinary complications. Early treatment of urethral injuries may be beneficial to male patients with urethral trauma, even in cases of severe injury.

PURPOSE: A step-based anastomotic urethroplasty is a standard technique for repairing the posterior urethra in patients with pelvic fracture urethral injury (PFUI). We aim to identify pre-operative factors, including results of conventional radiological imaging, for prediction of elaborated perineal or a combined abdominoperineal procedure. METHODS: Retrospective observational study on 114 consecutive patients undergoing urethroplasty for PFUI between January 2020 and December 2022 was conducted. Surgical procedures were categorized according to the Webster classification into two groups: steps 1-2 (group 1) and steps 3-4 or a combined abdominoperineal repair (group 2). Pre-operative pattern results of RGU/VCUG were categorized regarding the relation between the proximal urethral stump with the pubic symphysis: posterior urethral stump below (pattern 1) or above (pattern 2) the lower margin of the pubic symphysis. Patient demographics were assessed. Univariate and multivariate logistic regression analyses were utilized. RESULTS: Overall, 102 patients were enrolled in the study for data analysis. On the multivariate logistic regression analysis, the presence of erectile dysfunction (OR 4.5; p = 0.014), prior combined treatment (endoscopic and urethroplasty) (OR 6.4; p = 0.018) and RGU/VCUG pattern 2 (OR 66; p < 0.001) significantly increased the likelihood of the need of step 3 or higher. CONCLUSIONS: The need of step 3 or higher during urethroplasty for PFUI can be predicted pre-operatively with conventional imaging (RGU/VCUG). Patients with proximal urethral stump above the lower margin of pubic symphysis were about 66 times more likely to need step 3 or higher during urethroplasty.

RESUMEN La uretrografía retrógrada es la técnica de referencia (gold standard) utilizada clásicamente para hacer diagnóstico de lesiones de uretra. En este contexto se presenta un caso en el que se realizó tomografía computarizada con reconstrucción 3D con contraste intravenoso y endouretral, pudiendo reconstruir la uretra en toda su extensión en forma tridimensional. De esta manera se arribó al diagnóstico de certeza de la lesión de uretra. Como ventaja del método se menciona la posibilidad de diagnosticar ‒ con un solo estudio por imágenes‒ lesiones de todo el tracto urinario, órganos sólidos, huecos y lesión del anillo pélvico asociados al traumatismo, con una alta sensibilidad y especificidad sin necesidad de requerir otros estudios complementarios.
ABSTRACT Retrograde urethrography is the gold standard method for the diagnosis of urethral injuries. In this setting, we report the use of computed tomography with intravenous injection and urethral administration of contrast medium and 3D reconstruction of the entire urethra. The definitive diagnosis of urethral injury was made. The advantage of this method is the possibility of making the diagnosis of traumatic injuries of the entire urinary tract, solid organs, hollow viscera and of the pelvic ring within a single imaging test, with high sensitivity and specificity, with no need to perform other complementary tests.

Abstract Introduction: leiomyomas are benign mesenchymal tumors of smooth muscle origin that can develop in various locations. Urethral leiomyomas are rare, with approximately only 120 cases reported in the literature. These tumors often occur in the third and fourth decades of life but are rare in menopausal patients. In general, treatment involves surgery, only three recurrence reports in the literature. Description: a case report on a 56-year-old woman; the patient had type II diabetes mellitus and chronic high blood pressure, was overweight (body mass index, 27.1 kg/m2), and a smoker. Besides this, the patient presented symptoms of urinary obstruction and had a large urethral leiomyoma. The tumor was completely removed with no associated urethral lesions using a complex, combined abdominalvaginal surgical approach. Discussion: the management and treatment on urethral leiomyomas is challenging and have not been established yet due to the rarity of these tumors.
Resumo Introdução: os leiomiomas são tumores mesenquimais benignos de origem muscular lisa, podendo manifestar-se em diversas localizações. Os leiomiomas uretrais são raros, tendo apenas aproximadamente 120 casos relatados na literatura. São mais comuns na terceira e quarta décadas de vida, sendo raros em pacientes menopausadas. Em geral, são tratados cirurgicamente, com apenas três relatos de recidivas na literatura. Descrição: relato de caso de uma paciente do sexo feminino, 56 anos, portadora de diabetes mellitus do tipo II, hipertensão arterial crônica, sobrepeso (IMC 27,1Kg/m2) e tabagismo. Além disso, com quadro de sintomas obstrutivos urinários e portadora de um grande leiomioma uretral, este que foi completamente removido, através de uma desafiadora abordagem cirúrgica combinada (abdominal e vaginal), sem lesões uretrais associadas. Discussão: os leiomiomas uretrais são tumores raros e seu manejo é desafiador e ainda não foi estabelecido.

ABSTRACT Objective To present the evolution and the recent data on the etiology, diagnosis, management and outcomes of penile fracture (PF) with concomitant urethral injury. Materials and Methods We searched the Pubmed database between 1998 and 2019 using the following key words: "penile fracture", "fracture of penis", "trauma to penis", "rupture of corpora cavernosa", "urethral injury", "urethral rupture" and "urethral reconstruction". Results The incidence of urethral lesion in patients with PF varies by geographic region and etiology. Blood in the meatus, hematuria and voiding symptoms are highly indicative of urethral rupture. The diagnosis of PF is eminently clinical and complementary exams are not necessary. The treatment consists of urethral reconstruction and the most common complications found are urethral stenosis and urethrocutaneous fistula. Conclusion PF is an uncommon urological emergency, particularly in cases with urethral involvement. Urethral injury should be suspected in the presence of suggestive clinical signs, and diagnosis is usually clinical. Urgent urethral reconstruction is mandatory and produces satisfactory results with low levels of complications.

ABSTRACT Objective To validate the application of the bacterial cellulose (BC) membrane as a protecting barrier to the urethra. Materials and Methods Forty female Wistar rats (four groups of 10): Group 1 (sham), the urethra was dissected as in previous groups and nothing applied around; Group 2, received a 0.7cm strip of the BC applied around the urethra just below the bladder neck; Group 3, received a silicon strip with the same dimensions as in group 2; Group 4, had a combination of 2 and 3 groups being the silicon strip applied over the cellulosic material. Half of the animals in each group were killed at 4 and 8 months. Bladder and urethra were fixed in formalin for histological analysis. Results Inflammatory infiltrates were more intense at 4 months at lymphonodes (80% Grade 2), statistically different in the group 2 compared with groups 1 (p=0.0044) and 3 (p=0.0154). At 8 months, all samples were classified as grade 1 indicating a less intense inflammatory reaction in all groups. In group 2, at 8 months, there was a reduction in epithelial thickness (30±1μm) when com-pared to groups 1 (p=0.0001) and 3 (p<0.0001). Angiogenesis was present in groups 2 and 4 and absent in group 3. In BC implant, at 4 and 8 months, it was significant when comparing groups 4 with 1 (p=0.0159). Conclusion BC membrane was well integrated to the urethral wall promoting tissue remodeling and strengthening based on morphometric and histological results and may be a future option to prevent urethral damage.

ABSTRACT Objectives To study the usefulness of MRI in preoperative evaluation of PFUDD. Can MRI provide additional information on urethral distraction defect (UDD) and cause of erectile dysfunction (ED)? Materials and Methods In this prospective study, consecutive male patients presenting with PFUDD were included from Feb 2011 till Dec 2012. Those with traumatic spinal cord injury and pre-existing ED were excluded. Patients were assessed using IIEF questionnaire, retrograde urethrogram and micturating cystourethrogram (RGU+MCU) and MRI pelvis. Primary end point was erectile function and secondary end point was surgical outcome. Results Twenty patients were included in this study. Fourteen patients (70%) were ≤40years; fifteen patients (75%) had ED, seven patients (35%) had severe ED. MRI findings associated with ED were longer median UDD (23mm vs. 15mm, p=0.07), cavernosal injury (100%, p=0.53), rectal injury (100%, p=0.53), retropubic scarring (60%, p=0.62) and prostatic displacement (60%, p=0.99). Twelve patients (60%) had a good surgical outcome, five (25%) had an acceptable outcome, three (15%) had a poor outcome. Poor surgical outcome was associated with rectal injury (66.7%, p=0.08), cavernosal injury (25%, p=0.19), retropubic scarring (18.1%, p=0.99) and prostatic displacement (16.7%, p=0.99). Five patients with normal erections had good surgical outcome. Three patients with ED had poor outcome (20%, p=0.20). Conclusions MRI did not offer significant advantage over MCU in the subgroup of men with normal erections. Cavernosal injury noted on MRI strongly correlated with ED. Role of MRI may be limited to the subgroup with ED or an inconclusive MCU.

Objetivo: Revisar los resultados operatorios de nuestros pacientes con rotura traumática de uretra posterior, tratados a través del abordaje perineal progresivo y realizar una breve revisión de la literatura. Materiales y métodos: fueron analizadas las historias médicas de 7 pacientes en edades comprendidas entre 2 y 12 años, con lesiones uretrales asociadas con fracturas pélvicas, producidas entre marzo de 2005 y enero de 2017. Después del diagnóstico de la lesión, se realizó cistostomía derivativa en los 7 casos; en 2 de ellos con lesión rectal asociada se realizó, además, colostomía tipo Hartman en el momento de la derivación urinaria. La evaluación urológica preoperatoria para la uretroplastia definitiva incluyó uretrografía anterógrada y retrograda simultánea para determinar la separación entre los segmentos uretrales. Se decidió la reparación retardada de la uretra a través de abordaje perineal progresivo con un mínimo de 6 meses posterior al trauma. Resultados: El mecanismo de producción del trauma fue arrollamiento por vehículos a motor en 6 pacientes y aplastamiento por balancín petrolero en uno. La lesión uretral fue completa en todos. Tres presentaron complicaciones quirúrgicas; 2 estenosis uretrales que mejoraron con dilataciones y una fístula uretroperineal que cerró en forma espontánea sin consecuencias. Todos los pacientes se encuentran asintomáticos; ninguno ha requerido una nueva uretroplastia. Comentarios: Nuestros hallazgos con la implementación de este abordaje terapéutico coinciden con lo reportado en la literatura.
Objective: To evaluate the postoperative outcomes of our patients with posterior urethral traumatic rupture repaired by progressive perineal approach, and to conduct a brief review of the literature. Materials and methods: The clinical records of 7 patients aged between 2 to 12 years with urethral injuries due to pelvic fracture produced between March 2005 and January 2017, were reviewed. A suprapubic cystostomy for urinary drainage was constructed in the 7 patients immediately after diagnosis; two of them had concomitant rectum injuries thus a Hartmann's colostomy was also performed in them. The preliminary urologic appraisal for definite urethroplasty included a synchronous anterograde and retrograde cysto-urethrogram to determine separation of the urethral segments. The final selection of surgical procedure was delayed urethral repair by progressive perineal approach minimum 6 months after the trauma event. Results: The mechanism of injury was, blunt trauma after being struck by a moving vehicle in 6 patients and a crash injury caused by an oil rocker in one patient. The urethral disruption was complete in all patients. Three patients developed surgical complications: 2 urethral strictures which improved with dilatation and one urethral-perineal fistula with spontaneous closure and no associated complications. All patients remain asymptomatic; no patient has required a redo urethroplasty. Commentaries: Our findings through the implementation of this therapeutic approach are consistent with those reported in the literature. Conclusions: Progressive perineal access allows performing an anastomotic urethroplasty with good clinical outcomes in most patients.

ABSTRACT Erectile dysfunction (ED) is a common complication of pelvic fractures. To identify the vascular and neurogenic factors associated with ED, 120 patients admitted with ED after traumatic pelvic fracture between January 2009 and June 2013 were enrolled in this study. All patients answered the International Index of Erectile Function (IIEF-5) questionnaire. Nocturnal penile tumescence (NPT) testing confirmed the occurrence of ED in 96 (80%) patients on whom penile duplex ultrasound and neurophysiological testing were further performed. Of these ED patients 29 (30%) were demonstrated only with vascular abnormality, 41 (42.7%) were detected only with neural abnormality, 26 (27.1%) revealed mixed abnormalities. Of the 55 patients (29+26) with vascular problems, 7 patients (12.7%) with abnormal arterial response to intracavernous injection of Bimix (15mg papaverine and 1mg phentolamine), 31 (56.4%) with corporal veno-occlusive dysfunction and 17 (30.9%) had both problems. Of the 67 (41+26) patients with abnormal neurophysiological outcomes, 51 (76.1%) with abnormal bulbocavernosus reflex (BCR), 20 (29.9%) with pathological pudendal nerve evoked potentials (PDEPs) and 25 (37.3%) with abnormal posterior tibial somatosensory nerve evoked potentials (PTSSEPs). Our observation indicated that neurogenic factors are important for the generation of ED in patients with pelvic fracture; venous impotence is more common than arteriogenic ED.

We reported a case of a twenty-nine-year-old male who presented a penile fracture associated with urethral injury caused by a sexual intercourse. An ideal anamnesis and a special physical examination were determinant to correct diagnostics. Ultrasonography and uretrocistography must be performed for confirmation. The treatment is based on the presence of associated urethral injury. The surgical repair of cavernous body and urethra can produce good results, with a favorable prognosis and minimal rate of complications.

PURPOSE: Pelvic fracture urethral distraction defect is usually managed by the end to end anastomotic urethroplasty. Surgical repair of those patients with post-traumatic complex posterior urethral defects, who have undergone failed previous surgical treatments, remains one of the most challenging problems in urology. Appendix urinary diversion could be used in such cases. However, the appendix tissue is not always usable. We report our experience on management of patients with long urethral defect with history of one or more failed urethroplasties by Monti channel urinary diversion. MATERIALS AND METHODS: From 2001 to 2007, we evaluated data from 8 male patients aged 28 to 76 years (mean age 42.5) in whom the Monti technique was performed. All cases had history of posterior urethral defect with one or more failed procedures for urethral reconstruction including urethroplasty. A 2 to 2.5 cm segment of ileum, which had a suitable blood supply, was cut. After the re-anastomosis of the ileum, we closed the opened ileum transversely surrounding a 14-16 Fr urethral catheter using running Vicryl sutures. The newly built tube was used as an appendix during diversion. RESULTS: All patients performed catheterization through the conduit without difficulty and stomal stenosis. Mild stomal incontinence occurred in one patient in the supine position who became continent after adjustment of the catheterization intervals. There was no dehiscence, necrosis or perforation of the tube. CONCLUSION: Based on our data, Montis procedure seems to be a valuable technique in patients with very long complicated urethral defect who cannot be managed with routine urethroplastic techniques.
