RESUMO

OBJECTIVES: To evaluate factors predicting recurrence after treatment and to assess the best rescue option for patients failing buccal mucosa graft (BMG) urethroplasty. MATERIALS AND METHODS: We evaluated the data from 575 patients treated with ventral onlay BMG urethroplasty. Multivariable Cox regression analysis was performed to identify predictors of BMG urethroplasty failure, and their effect on failure risk was estimated using the Kaplan-Meier method and compared using log-rank tests. Then, for those patients who underwent a rescue treatment, namely, direct visual internal urethrotomy (DVIU) vs open urethroplasty, we assessed the probability of success after retreatment using the Kaplan-Meier method and regression tree analyses. RESULTS: On multivariable Cox regression analysis, only stricture length ≥5 cm (hazard ratio 3.46, 95% confidence interval 1.50-7.94; P = 0.003) was a predictor of failure. A total of 103 patients had at least one re-intervention. Notably, 12-month success rates after first rescue DVIU, second rescue DVIU, third rescue DVIU, and fourth rescue DVIU were 66.3%, 62.5%, 37.5% and 25%, respectively. Conversely, for those patients who underwent open urethroplasty retreatment, success rates at 12 months were 83.3%, 79%, 92.3% and 75% after BMG ventral onlay, first rescue DVIU, second rescue DVIU and third rescue DVIU, respectively. These data were confirmed in regression tree analyses. CONCLUSION: Ventral BMG urethroplasty fails in approximately one out of five patients. Despite DVIU as a rescue treatment being a good option, its success rate becomes lower as the number of DVIU treatments performed increases. Conversely, open urethroplasty improves patient outcomes in almost three out of four patients, even in the case of previous failed DVIU treatments for stricture recurrence.

RESUMO

PURPOSE: The optimal harvesting site for oral grafting in patients with urethral strictures remain controversial, with no study investigating morbidity on large scale. We aimed to compare typical single cheek harvesting vs atypical lingual, labial or bilateral cheeks harvesting in terms of complications and patient-reported outcomes. METHODS: Within 827 patients treated at our referral center with oral graft urethroplasty, we compared typical vs atypical harvesting techniques. A self-administered, semiquantitative, non-validated questionnaire assessed early (10 days) and late (4 months) postoperative complications and patient-reported outcomes. A semiquantitative score was calculated according to patient responses, and it was used to assess early (6 questions) and late (13 questions) patient dissatisfaction status. Patients were defined early and/or late dissatisfied when they scored ≥ 7 and ≥ 10 at the early or late questionnaires, respectively. RESULTS: Between 1998 and 2019, our patients predominantly received typical single cheek harvesting (89% vs 11%), with + 1.5% increase rate per year (p < 0.001). Early and late dissatisfied patients were, respectively, 170 (23%) vs 39 (44%) and 59 (8%) vs 16 (18%) in the typical vs atypical groups. Atypical harvesting was associated with higher rates of early (Odds ratio [OR]: 2.34; 95% Confidence interval [CI] 1.44-3.75; p = 0.001) and late (OR: 2.37; 95%CI 1.22-4.42; p = 0.008) postoperative dissatisfaction. CONCLUSIONS: Typical single cheek harvesting was the preferred surgical option at our center and it was associated with negligible early and late rates of complications and patient's dissatisfaction. Conversely, atypical lingual, labial or bilateral cheeks harvesting was associated with higher complications and frequent patient dissatisfaction.

RESUMO

PURPOSE: To conduct a rigorous assessment of in-hospital morbidity after urethroplasty according with the European Association of Urology (EAU) guidelines for complication reporting. METHODS: We retrospectively (2015-2019) identified 469 consecutive patients receiving urethroplasty (e.g. bulbar urethroplasty with grafts, penile urethroplasty with/without grafts/flaps, Johanson, de novo or revision perineostomy, end-to-end anastomosis, meatoplasty and/or meatotomy) at our tertiary care institution. Complications were graded with Clavien-Dindo score and Comprehensive Complication Index (CCI). Complications were classified in: bleeding no gastrointestinal, cardiac, gastrointestinal, genitourinary, infectious, neurological, oral, wound, miscellaneous, and pulmonary. Logistic regression tested for predictors of in-hospital complications and prolonged hospitalization (> 75th percentile). Kaplan-Meier and Cox regression investigated the effect of complications on failure after urethroplasty. RESULTS: Overall, 161 (34.3%) patients experienced at least one complication. Of those, 47 (10%) experienced two or more complications and 59 (12.6%) experienced at least one Clavien-Dindo ≥ II complication. Only two patients had Clavien-Dindo III complications. Infectious was the most frequent complication, and de novo or revision perineostomy was associated with the highest rate of complications. The occurrence of any complications, as well as complication with Clavien-Dindo ≥ II were associated with prolonged hospitalizations, but not with higher rates of post-urethroplasty failure. CONCLUSIONS: Complications after urethroplasty were common events, but rarely with severe sequelae. Infectious were the most common complications and perineostomy was the type of urethroplasty with the highest rate of complications. The application of the EAU recommendations allowed the identifications of a higher number of complications after urethroplasty if compared with previous reports based on unsupervised chart review.

RESUMO

OBJECTIVES: To develop and validate the Urethroplasty Training and Assessment Tool (UTAT) using Healthcare Failure Mode and Effect Analysis (HFMEA) for training and assessment of urology trainees learning this urethral reconstruction technique, as urethroplasty is the 'gold standard' treatment for long and recurrent urethral strictures and with a variety of techniques and a lack of standardised reconstructive curricula, there is a need for procedure-specific training tools to improve surgeon training and patient safety. MATERIALS AND METHODS: This international observational study was performed over an 11-month period. The HFMEA was used to identify and evaluate hazardous stages of urethroplasty to develop the UTAT. Hazard scores were calculated for the included steps of urethroplasty. Content validation was performed by 12 expert surgeons and multidisciplinary teams from international tertiary centres. RESULTS: The HFMEA process resulted in an internationally validated UTAT. Hazard scores ≥4 and single point weaknesses were included to implement actions and outcome measures. Content validation was achieved by circulating the process map, hazard analysis table, and developed tools. Changes were implemented based on the feedback received from expert surgeons. The content validated dorsal onlay buccal mucosa graft bulbar UTAT contained five phases, 10 processes and 23 sub-processes. CONCLUSIONS: The modular UTAT offers a comprehensive validated training tool developed via a detailed HFMEA protocol. This may be utilised to standardise the training and assessment of urology trainees.

RESUMO

The surgical treatment of bulbar urethral strictures is still one of the most challenging reconstructive surgery problems. Bulbar urethral strictures are usually categorized as traumatic and non-traumatic strictures depending on the aetiology. The traumatic strictures are caused by trauma and they determine disruption of the urethra with obliteration of the urethral lumen, ending with fibrotic gaps between the urethral ends. Differently, the non-traumatic urethral strictures are mainly caused by catheterization, instrumentation, and infection, or they can also be idiopathic. They are usually asso-ciated with spongiofibrosis of the segment of the urethra that has been involved. Worldwide, two different surgical approaches are currently adopted for bulbar urethral repair: transecting techniques with end-to-end anastomosis and non-transecting techniques followed by grafting. Traumatic obliterated strictures require transection of the urethra allowing complete removal of the fibrotic tissue that involves the urethral ends. Conversely, non-traumatic, non-obliterated urethral strictures require augmentation of the urethral plate using oral mucosa grafts. Nowadays, it is still difficult to choose the correct surgical management for non-obliterated bulbar stricture repair. Indeed, different surgical techniques have been proposed (pedicled flap vs free graft, dorsal vs ventral placement of the graft, non-transecting technique using or non-using free graft, etc.) but none emerged as the best solution since all techniques have showed similar success and complication rates. Consequently, the final choice is still based on surgeon's preferences and patient's characteristics. Within the current manuscript, we like to present some of our tips and tricks that we developed along our prolonged surgical experience on the treatment of bulbar urethral strictures. These might be of interest for surgeons that approach this complex surgery. Moreover, our suggestions want to be useful regardless the type of chosen technique being adaptable for different scenario.

RESUMO

OBJECTIVES: To describe, step by step, a new one-stage dorsal skin flap urethroplasty for penile stricture repair. MATERIALS AND METHODS: The surgery was accomplished through a midline incision on the ventral penile surface, the urethra was fully dissected from the corpora cavernosa and longitudinally opened along its dorsal surface. A penile skin island, based on the dartos fascia flap, was dissected and moved over the corpora cavernosa, and the urethra was moved and sutured over the penile skin flap. RESULTS: Out of the 12 cases, 10 were classified successful and there were two failures. The operating time was 60 min. There was no postoperative fistula or urethral diverticulum. CONCLUSION: Our modified Orandi's technique was easy and feasible, and avoided fistula and diverticulum formation after repair.

RESUMO

PURPOSE: We investigated the success rate of different surgical techniques for bulbar stricture repair. METHODS: Retrospective study of patients with bulbar urethral strictures treated using different techniques. The primary outcome of the study was to evaluate the overall results of treatment (success vs. failure); the secondary outcome was to evaluate the outcome according to any surgical technique. Cysto-urethrography was performed 1 month following surgery. Patients underwent clinical evaluation, uroflowmetry and residual urine measurement every 6 months for 2 years after surgery and later once on year. When patient showed obstructive symptoms, Qmax < 12 ml/s, the urethrography was repeated. Patients who underwent further treatment for recurrent stricture were classified as failures. A bivariable and multivariable statistical analysis was performed. RESULTS: Overall, 1242 patients were included in the study with mean age 40 years (range 12-84). Median stricture length was 4 cm (range 1-8). The median follow-up was 103 months (range 12-362). Over 1242 patients, 916 (73.8%) were success and 326 (26.2%) failures. Fourteen different surgical techniques showed a success rate ranging from 87.5 to 14.3%. The multivariable analysis showed that stricture length was an independent predictor factors for failure: p < 0.0001 CI 1146-1509. End-end anastomosis and oral mucosa graft urethroplasty are independent predictor factor of success after internal urethrotomy failure. CONCLUSIONS: Our results showed that treatment of bulbar urethral stricture is satisfactory on 73.8% of patients, but with a wide range of success rate (from 14.3 to 87.5%) using different techniques. Oral mucosa is greatly superior to the skin as substitute material.

RESUMO

INTRODUCTION: Repair of post-TURP sphincter urethral strictures represents challenging problem, due to the risk of urinary incontinence after the repair. We described a surgical technique we use to repair these strictures preserving urinary continence in patients with incompetent bladder neck. MATERIALS AND METHODS: An observational, retrospective, study was conducted to include patients with post-TURP urethral strictures in the area of distal sphincter. We included only patients with complete clinical data and follow-up who previously underwent TURP or HOLEP or TUIP, and subsequently developed proximal bulbar urethral strictures close to the membranous urethra and the related distal urethral sphincter. Patients were included, if they were fully continent after TURP or other procedures to treat BPH. The primary outcome of the study was treatment failure, defined as the need for any post-operative instrumentation. Secondary outcome was post-urethroplasty urinary continence. Patients showing stricture recurrence or post-operative incontinence were classified as failure. RESULTS: Overall, 69 patients were included in the study. Median patient's age was 67 years; median stricture length was 4 cm. Thirty-tree patients (47.8%) underwent previous urethrotomy. Median follow-up was 52 months. Out of 69 patients, 55 (79.7%) were classified as success and 14 (20.3%) as failure. Out of the whole cohort, thus, 11/69 (16%) have a risk of recurrent strictures and 3/69 (4.3%) have incontinence. CONCLUSIONS: The use of modified ventral onlay graft urethroplasty, using particular non-aggressive steps, is a suitable surgical technique for repair of sphincter urethral stricture in patients who underwent BPH transurethral surgery, using different procedures (TURP, HOLEP, TUIP).

RESUMO

PURPOSE: The sonourethrogram is a useful alternative to the traditional retrograde urethrogram to evaluate anterior urethral strictures. With the development of 3-dimensional reconstructive techniques 3-dimensional urethral imaging can provide more accurate and useful information to enable the surgeon to make the best surgical decisions. We evaluated the accuracy and efficacy of a 3-dimensional reconstructed digital model of the urethra based on the sonourethrogram to assess anterior urethral disease. MATERIALS AND METHODS: A total of 50 patients with an anterior urethral stricture and 10 healthy volunteers were enrolled in this study from April 2014 to January 2017. All patients and volunteers underwent sonourethrogram and retrograde urethrogram. Three-dimensional urethral models were reconstructed based on the sonourethrogram. Stricture length and location on retrograde urethrogram or sonourethrogram based images were compared with those found at operation. RESULTS: The 3-dimensional digital model revealed the entire anterior urethra, including the navicular fossa, and the penile and bulbar parts. The semitransparent model clearly demonstrated the structure of the corpus spongiosum and inside the urethral lumen. Further information on spongiofibrosis could also be seen in the 3-dimensional digital model. There was no significant difference in stricture length or location in the 3-dimensional model compared with retrograde urethrogram imaging and actual surgical findings. However, the latest technique could only reconstruct the short segment of the anterior urethra due to the probe width limitation. CONCLUSIONS: The 3-dimensional computerized model based on the sonourethrogram is a novel and effective technique of evaluating anterior urethral strictures.

RESUMO

PURPOSE: We investigated whether tissue engineered material may be adopted using standard techniques for anterior urethroplasty. MATERIALS AND METHODS: We performed a retrospective multicenter study in patients with recurrent strictures, excluding those with failed hypospadias, lichen sclerosus, traumatic and posterior strictures. A 0.5 cm2 oral mucosa biopsy was taken from the patient cheek and sent to the laboratory to manufacture the graft. After 3 weeks the tissue engineered oral mucosal MukoCell® graft was sent to the hospital for urethroplasty. Four techniques were used, including ventral onlay, dorsal onlay, dorsal inlay and a combined technique. Cystourethrography was performed 1 month postoperatively. Patients underwent clinical evaluation, uroflowmetry and post-void residual urine measurement every 6 months. When the patient showed obstructive symptoms, defined as maximum urine flow less than 12 ml per second, the urethrography was repeated. Patients who underwent further treatment for recurrent stricture were classified as having treatment failure. RESULTS: Of the 38 patients with a median age of 57 years who were included in study the strictures were penile in 3 (7.9%), bulbar in 29 (76.3%) and penobulbar in 6 (15.8%). Median stricture length was 5 cm and median followup was 55 months. Treatment succeeded in 32 of the 38 patients (84.2%) and failed in 15.8%. Success was achieved in 85.7% of ventral onlay, 83.3% of dorsal onlay, 80% of dorsal inlay and 100% of combined technique cases. No local or systemic adverse reactions due to the engineered material were noted. CONCLUSIONS: Our findings show that a tissue engineered oral mucosa graft can be implanted using the same techniques suggested for anterior urethroplasty and native oral mucosa, and guaranteeing a similar success rate.

RESUMO

INTRODUCTION: Complex penile strictures are usually repaired using a two-stage urethroplasty. Buccal mucosal graft (BMG) placed in the first stage can have a significant contraction rate, which may require a subsequent revision surgery. We describe a composite two-stage penile urethroplasty using BMG for patients of complex penile strictures who have some salvageable urethral plate. METHODS: Within a multi-institutional cohort, 82 patients underwent a two-stage urethroplasty for complex stricture of the penile urethra. Of these 42 patients who underwent our composite two-stage penile urethroplasty using BMG implanted at the second-stage were included. Patients with genital lichen sclerosus or incomplete clinical records were excluded from this study. The primary outcome of the study was to evaluate stricture-free success rate. RESULTS: Of total 42, 4 patients were lost to follow-up. 42% of stricture etiology was failed hypospadias repair. Mean stricture length was 4.5 cm (range 3-8 cm). Seventeen (44.7%) patients had undergone the previous urethroplasty. At a median follow-up of 44 months, of 38 patients, 34 (89.5%) were successful, and 4 (10.5%) had a recurrence. No patient required revision surgery before the second-stage and required redo buccal graft harvesting for subsequent urethroplasty. CONCLUSIONS: The composite two-stage technique in repairing complex penile urethral strictures is a valid and reproducible surgical treatment for complex penile stricture and it may reduce the rate of contraction of the transplanted BMG.

RESUMO

PURPOSE: To report the clinical features of pelvic fracture urethral injury (PFUI) and assess the real effect of factors that are believed to have adverse effects on delayed urethroplasty. METHODS: An observational descriptive study in a single urological center examined 376 male patients diagnosed with PFUI who underwent open urethroplasty from 2009 to 2013. Analyzed factors included patient age at the time of injury, etiology of PFUI, type of emergency treatment, concomitant injuries, length and position of stricture, type of urethroplasty and the outcome of surgery. Univariate and multivariate logistic regression analyses were applied, together with analytical statistic methods such as t test and Chi-square test. RESULTS: The overall success rate of delayed urethroplasty was 80.6 %. Early realignment was associated with reduced stricture length and had beneficial effect on delayed surgery. Concomitant rectum rupture, strictures longer than 1.6 cm and strictures closer than 3 cm to the bladder neck were indicators of poor outcome. Age, type of injury, urethral fistula and bladder rupture were not significant predicators of surgery outcome. Failed direct vision internal urethrotomy and urethroplasty had no significant influence on salvage operation. CONCLUSIONS: The outcome of posterior urethroplasty is affected by multiple factors. Early realignment has beneficial effect; while the length and position of stricture and its distance to bladder neck plays the key role, rectum rupture at the time of injury is also an indicator of poor outcome. The effect of other factors seems insignificant.

RESUMO

PURPOSE: We investigated the early and late complications after oral mucosal graft harvesting, and reported the independent predictors of outcome via multivariable analysis. MATERIALS AND METHODS: We performed a retrospective descriptive study of 553 patients from whom an oral mucosa graft was harvested for urethroplasty from single or bilateral cheeks. Patients who underwent oral mucosa harvesting from the lip, the tongue or from the cheek and lip at the same time were excluded from analysis. The oral graft was harvested in an ovoid shape with closure of the wound. Postoperative early and late complications were investigated using a self-administered, nonvalidated, semiquantitative questionnaire. There were 6 questions on early complications, and 13 questions investigated late complications and patient satisfaction. RESULTS: Descriptive statistics of categorical variables focused on frequencies and proportions. Univariable and multivariable analyses were used to predict early and late dissatisfaction of patients. Bleeding was reported in 3.4% of patients. Overall 53.2% of patients did not report any pain and 36.3% reported no swelling. Late complications analysis showed that 95.5% of patients declared that the surgical closure of the wound did not cause any difficulty in opening the mouth or problems with smiling (98.2%) and/or dry mouth (95.8%). Overall 98.2% of patients were satisfied with the procedure. Univariable and multivariable analyses revealed that bilateral graft harvesting was the only significant predictor of patient dissatisfaction (OR 2.85, p = 0.01 and OR 2.72, p = 0.02; respectively). CONCLUSIONS: Harvesting the oral mucosa ovoid graft from a single cheek with closure of the wound is a safe procedure with high rates of patient satisfaction.

RESUMO

PURPOSE: We investigated deterioration of the success rate of penile and bulbar substitution urethroplasty. MATERIALS AND METHODS: We performed a retrospective descriptive analysis of patients who underwent substitution urethroplasty between July 1994 and September 2007. Inclusion criteria included 1-stage anterior urethroplasty using penile skin or oral mucosa with a minimum of 6 years followup. Patients with posterior urethral stricture, failed hypospadias or incomplete clinical records were excluded from analysis. The primary study outcome was postoperative failure-free survival and the secondary outcome was to identify significant predictors of treatment failure. The clinical outcome was considered a failure when any postoperative instrumentation was needed. Descriptive statistical analysis was done as well as Kaplan-Meier analysis, and univariable and multivariable Cox regression analysis. RESULTS: A total of 359 patients were included in study. Median followup was 118 months. Of the procedures 265 (73.8%) were successful and 94 (26.2%) failed, including 91 (96.8%) within the first 5 years. Substitute tissue type (oral mucosa vs skin) was the only significant predictor on univariable analysis (HR 1.86, p = 0.005). This result was confirmed by multivariable analysis adjusting for age at surgery, stricture length and etiology, urethroplasty type and previous treatments (HR 2.26, p = 0.001). CONCLUSIONS: Deterioration after anterior 1-stage substitution urethroplasty seems to develop within the first 5 years. Oral mucosa showed greater failure-free survival than penile skin and 1-stage penile urethroplasty showed the same success rate as bulbar urethroplasty.

RESUMO

OBJECTIVES: To evaluate the results of various reconstructive surgical procedures in patients with failed hypospadias repair. METHODS: We performed a retrospective, observational, descriptive chart analysis of patients treated for complications after primary hypospadias repair at two tertiary European centers from 1998 to 2007. Study inclusion criteria were: patients presenting urethral, glans or corpora cavernosa defects and/or penile and genital deformities. Exclusion criteria were: precancerous or malignant penile lesions, incomplete data on medical charts and any condition that would interfere with the patient's ability to provide an informed consent. Preoperative evaluation included urine culture, urethrography and urethroscopy. The patients were classified into four groups according to the type of surgery. Success was defined as a normal functional urethra with apical meatus, no residual chordee or cosmetic deformity of the genitalia. The need for meatal or urethral dilation, complications or poor cosmesis requiring revision was considered a failure. RESULTS: A total of 1.176 patients(mean age 31 years) were evaluated and treated. Nine hundred fifty-three patients (81% ) were treated in Serbia and 223 (19% ) in Italy. Mean follow-up was 60.4 months. Group 1 included 301 patients (25.6% ) who underwent urethroplasty. Group 2 included 60 patients (5.1% ) who underwent corporoplasty. Group 3 included 166 patients (14.1% ) who underwent urethroplasty and corporoplasty. Group 4 included 649 patients (55.2% ) requiring complex resurfacing of the genitalia. Evaluations were scheduled 3, 6 and 9 months postoperatively and annually thereafter. At follow-up, patients underwent a physical examination and uroflowmetry. Out of the 1.176 cases, 1.036 (88.1% ) were classified as successful and 140 (11.9% ) as failures. The success rate was 89.7% in Group 1, 96.7% in Group 2, 88.5% in Group 3, and 86.4% in Group 4, respectively. CONCLUSIONS: Failed hypospadias presents a variety of surgical difficulties. Patients requiring complex repair should be referred to a specialized center of expertise.

RESUMO

OBJECTIVES: While efforts have been made to study erectile function in patients with urethral stricture, very few prior investigations have specifically assessed erectile function in men with failed hypospadias surgery. We set forth to assess the baseline erectile function of men with hypospadias failure presenting for urethroplasty as adults. METHODS: Retrospective data was analyzed on 163 adult patients with prior failed hypospadias repair who presented for urethroplasty from 2002-2007 at two sites in the United States and Italy. All patients had completed the International Index of Erectile Function (IIEF) pre-operatively. Standard IIEF-6 categories were used to assess baseline level of erectile dysfunction (ED) defined as none (≥ 26), minimal (18-25) ,moderate (11-17), and severe (≤ 10). A subset of 13 hypospadias patients prospectively completed the IIEF questionnaire pre and post- operatively. RESULTS: The mean age at presentation for urethroplasty was 39.7 years. Based on IIEF-6 scores, 54% of patients presented with some degree of ED with 22.1%, 3.7%, and 28.2% reporting severe, moderate and mild ED respectively. While the oldest patient population (>50) had the highest incidence of severe ED (38.9%), the youngest age group (=30) had a 60% rate of ED with 18% classified as severe (Table I). Subset analysis of 13 failed hypospadias patients following urethroplasty revealed that 11 (85%) patients had the same or improved erectile function following surgery. CONCLUSIONS: Patients presenting for repair after hypospadias failure often require complex penile reconstruction impacting both urinary as well as sexual quality of life. Among these patients there appears to be a high baseline prevalence of ED. Older patients had a higher incidence of more severe ED; however, the majority of younger patients still presented with some form of ED and a significant number with severe ED. Urethroplasty does not appear to negatively impact erectile function in men with previous hypospadias failure; however a disease specific questionnaire is needed to fully address this issue.

RESUMO

Oral mucosa has been the most popular substitute material for urethral reconstructive surgery because it is easy to harvest, is easy to access, has a concealed donor site scar, and obviates most of the problems associated with other grafts. However, the success of using oral mucosa for urethral surgery is mainly attributed to the biological properties of this tissue. Herein, the surgical steps of harvesting oral mucosa from the inner cheek are presented with an emphasis on tips and tricks to render the process easier and more reproducible and to prevent intra and post-operative complications. The following steps are emphasized: Nasal intubation, ovoid shape graft, delicate harvesting leaving the muscle intact, donor site closure and removal of submucosal tissue.

RESUMO

UNLABELLED: WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: The incidence of specific aetiologies of urethral stricture disease has been reported from a variety of series throughout the world. Most reported urethral stricture series are from single institutions or from a specific region of the world. We provide a multi-centred series to compare aetiologic incidence between differing regional populations. OBJECTIVE: To better understand distinct regional patterns in urethral stricture aetiology and location among distinct regional populations. PATIENTS AND METHODS: Data on 2589 patients who underwent urethroplasty from 2000 to 2011 were collected retrospectively from three clinical sites, including 1646 patients from Italy, 715 from India and 228 from the USA. Data from all sites were single-surgeon series. As the data from the Italian and US cohorts were similar in aetiology, location and demographics, we combined these data to form group 1, and compared this group with men in the Indian cohort, group 2. Age, stricture site and primary stricture aetiology were identified for each patient. Stricture site and primary aetiology were determined by the treating surgeon. Primary aetiology was defined as iatrogenic, trauma including pelvic-fracture-related urethral injury (PFUI), lichen sclerosus (LS), infectious, congenital, or unknown. RESULTS: There were more penile strictures (27 vs 5%) and fewer posterior urethral stenoses (9 vs 34%) in group 1. There were more iatrogenic strictures identified in group 1 (35 vs 16%). When comparing the aetiology of iatrogenic strictures alone, more strictures in group 1 were attributable to failed hypospadias repair (49 vs 16%). More patients presented with LS (22 vs 7%) and external trauma (36 vs 16%) in group 2. Prevalence of strictures of infectious aetiology was low (1%) with similar proportions between the two groups. CONCLUSIONS: We have shown that significant regional differences in stricture aetiology exist in a large multicentre cohort study. Group 1 had a higher proportion of penile strictures, largely owing to more iatrogenic strictures and, in particular, failed hypospadias repair. Group 2 had a higher proportion of PFUI and LS-associated urethal stricture. Identified infection-related urethral stricture was rare in all cohorts. Significant regional differences in stricture aetiology exist and should be considered when analysing international outcomes after urethroplasty. These data may also help the development of international disease prevention and treatment strategies.

RESUMO

INTRODUCTION: Various urethroplasty techniques have been used to treat urethral stricture. Whether the patient erectile function is affected by this open surgery is still controversial. AIM: The aim of this study is to determine the relationship between erectile function and open urethroplasty. METHODS: A systematic review of the literature was performed using Medline, Embase, the Web of Science, and the Cochrane Library databases through October 2012 to identify articles published in any language that examined the effect of open urethroplasty on the risk of erectile dysfunction (ED). This meta-analysis was conducted according to the guidelines for the meta-analysis of observational studies in epidemiology. MAIN OUTCOME MEASURES: The incidence of ED after urethroplasty. RESULTS: This meta-analysis consisted of 23 cohort studies, which included 1,729 cases. No significant difference was noticed in patients with anterior urethral stricture before or after intervention (odds ratio [OR] = 0.86; 95% confidence interval [CI]: 0.52-1.40; P = 0.53). While statistical difference in the incidence of ED was revealed in patients before and after intervention for a posterior urethral (OR = 2.51; 95% CI: 1.82-3.45; P < 0.001), further comparisons demonstrated that most anterior urethroplasties did not have an obvious effect on patient erectile function. However, it seems that the incidence of ED was higher in the bulbar anastomosis group than in the oral graft urethroplasty group (OR = 0.32 95% CI: 0.11-0.93; P = 0.04). For the posterior urethroplasty, previous operative history did not show a strong relationship with ED. No statistically significant difference in the risk of ED was demonstrated comparing the posterior urethral reconstructive techniques included in this analysis. CONCLUSION: The adverse effect of urethroplasty itself on erectile function is limited, as more patients recover erectile function after urethral reconstruction. For anterior urethroplasty, bulbar anastomosis might cause a slightly higher incidence of ED than other operations. For posterior urethroplasty, trauma might be the main cause of ED.
