J Pediatr Urol 2024; 20:503.e1-503.e8. [PMID: 38704298 DOI: 10.1016/j.jpurol.2024.02.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/06/2023] [Revised: 02/21/2024] [Accepted: 02/29/2024] [Indexed: 05/06/2024]
Abstract
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.

Retrospective analysis of urethral anastomosis with ancillary maneuvers and intraoperative biaxial defect measurements to achieve a tension free guidance system for redo PFUDD treatment. BMC Urol 2024; 24:82. [PMID: 38594657 PMCID: PMC11003013 DOI: 10.1186/s12894-024-01456-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2023] [Accepted: 03/15/2024] [Indexed: 04/11/2024] Open
Abstract
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.

Abstract
Objectives To assess the effect of redo inferior pubectomy on the management of complicated pelvic fracture urethral injury (PFUI) in patients with a history of failed anastomotic urethroplasty. Materials and methods We retrospectively reviewed all patients receiving redo anastomotic urethroplasty with redo inferior pubectomy for failed PFUI between January 2010 and December 2021. Patients with incomplete data and those who were lost to follow-up were excluded. Successful urethroplasty was defined as the restoration of a uniform urethral caliber without stenosis or leakage and further intervention. Functional results, including erectile function and urinary continence, were evaluated. Descriptive statistical analyses were then performed. Results Thirty-one patients were included in this study. Among them, concomitant urethrorectal fistula occurred in 2 patients, and concomitant enlarged bladder neck occurred in 1. The stenosis site was the bulbomembranous urethra in 2 patients and the prostatomembranous urethra in 29. The mean length of urethral stenosis in all patients was 3.1 cm (range, 2.0-5.0 cm). After a mean follow-up of 34.6 months, the final success rate was 96.8%. The incidence of erectile dysfunction reached 77.4% (24/31). Normal continence was achieved in 27 (87.1%) patients. One patient developed urinary incontinence of grade II requiring urinary pads because of an enlarged bladder neck. According to the Clavien-Dindo classification, postoperative complications of grade I occurred in 7 patients and grade II in 4. Conclusions Repeat anastomotic urethroplasty with repeat inferior pubectomy provides reliable success rates for failed PFUI. In complicated cases, it should be known and mastered.

Abstract
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.

Abstract
Rectourethral fistula (RUF) is an infrequent but severe complication of the treatment of prostate cancer. Herein, we describe a new surgical approach used successfully in 3 patients that incorporates a partially de-epithelialized mid-perineal scrotal flap (MPSF), used as interposition flap, that can be used in almost every patient with RUF after radiotherapy, regardless of having or not a concomitant posterior urethra or bladder neck stricture or contracture that might require a simultaneous urethroplasty. The interposition flap includes well vascularized subcutaneous fat tissue by distal vascular branches of the internal pudendal vessels that reaches without tension the deep perineum up to the posterior bladder neck. The MPSF is a time efficient procedure that allows excellent access to the bulbar urethra and to the surgical plane between rectum and prostate and it does not require a separate incision for the flap harvesting procedure when required.

Abstract
INTRODUCTION The management of post-traumatic rupture of the posterior urethra remains controversial, leaving the choice between early endoscopic realignment (EER) or suprapubic catheterization with deferred urethroplasty. The objective is to compare the results of endoscopic realignment and those of urethroplasty in terms of voiding. PATIENTS AND METHODS We underwent a retrospective study collating all patients managed for post-traumatic complete urethral rupture between 2010 and 2020. These patients were subdivided into two groups: a first one including those who had an endoscopic realignment and a second one including those who had a deferred urethroplasty. We studied the quality of voiding and the complications that occurred in each group. The success of the technique was defined by the resumption of a satisfactory voiding, and the absence of recourse to the urethroplasty in case of endoscopic realignment. Satisfactory voiding was defined by a Qmax ≥ 15 mL/s and a post-void residual (PVR) < 150 ml by ultrasound. RESULTS Fifty-eight patients were identified. The mean age was 32 ± 12 years. Endoscopic realignment was performed in 26 patients. Satisfactory voiding was reported in 16 patients (61.53%). Recourse to internal urethrotomy after realignment was reported in 7 patients (26.92%). Three failures of endoscopic realignment were reported, necessitating an urethroplasty. Two patients reported urinary incontinence. Urethroplasty was performed in 32 patients. Satisfactory voiding was noted in 22 patients (68.75%). The use of internal urethrotomy after surgery was reported in 5 patients (15.62%). Three patients had treated urinary incontinence. Comparing the two groups, there was no significant difference in postoperative IPSS, flow rate (Qmax), post-void residual urine volume (PVR), satisfactory voiding, and stress urinary incontinence. CONCLUSION The voiding outcomes were comparable for both techniques. We conclude that endoscopic realignment can be indicated in first intention, provided certain conditions are met, in order to minimize the morbidity of prolonged suprapubic drainage.

Abstract
Webster described a step-based perineal approach for repairing the posterior urethra in patients with pelvic fracture urethral injury (PFUI). The higher the complexity of the step, the higher the morbidity for the patient and the lower the surgical outcomes. We evaluated the outcomes of anastomotic urethroplasty (especially Step 4 or higher) or substitution urethroplasty in patients with PFUI at our center. Between 2013 to 2021, we retrospectively collected data on patients with PFUI. Surgical procedures were categorized according to the Webster classification and rates of each step were reported. The success rate was defined as Qmax above 10 mL/s and no need for further treatment. In this period, 737 male patients with PFUI were surgically treated. Notably, 18.8%, 17.6%, 46%, 1.8%, and 5.6% of included patients received steps 1, 2, 3, and 4 and the abdominoperineal approach, respectively. In 68 (9.2%) patients, the substitution of urethroplasty with a pedicled preputial tube (PPT) was needed. The success rate was 69.2% in Step 4, 74.4% in the abdominoperineal approach, and 86.4% in PPT; however, recurrence-free survival was not significantly different between groups (p = 0.22). Step 4 perineal anastomotic urethroplasty represents a surgical option in the armamentarium of PFUI treatment. Indications should be carefully reviewed to improve patient selection and avoid surgical failure, stopping at the step which first gives a tension-free anastomosis.

Abstract
INTRODUCTION The management of traumatic urethral strictures remains a challenge for urologists. Alteration of the pelvic anatomy and the significant fibrosis generated by the trauma make surgical repair complex. In most cases, the existing defect between the urethral ends is small, and the ideal treatment is end-to-end perineal urethroplasty. Cases of extensive strictures that are left with long gap defects may require the use of different sequential maneuvers to achieve a tension-free anastomosis. OBJECTIVE To describe the experience at our center with urethral strictures induced by closed perineal trauma. MATERIALS AND METHODS A retrospective analysis of 116 patients who underwent urethroplasty for urethral stricture after blunt perineal trauma at our center between 1965 and 2020 was conducted. Demographic data, date, mechanism of action of the trauma, emergency management, previous urethral interventions, surgical technique carried out in our center, complications, presence of erectile dysfunction, and urinary incontinence were collected. RESULTS 82 patients (70.7%) presented with pelvic fractures. The most frequent etiology of trauma was traffic accidents (68%), followed by crushing injuries (24%). Suprapubic cystostomy was placed in 50.2% of patients, and urethral realignment was performed in 25.3%. The mean stricture length was 2.2 cm, affecting mostly the membranous urethra (67%). During surgery, it was necessary to perform crural separation in 61.5% and partial pubectomy in 18.8% of the cases. Erectile dysfunction developed after trauma in 40.5% of cases, while new erectile dysfunction was noted in 4.3% of patients after surgery. Surgery was successful in 91.3% of cases, with a median follow-up of 16 (6-47) months. CONCLUSION Delayed anastomotic urethroplasty offers a high success rate in traumatic urethral strictures.

Abstract
OBJECTIVES We report our surgical experience of transperineal bulbovesical anastomosis (BVA) for extensive posterior urethral stenosis (PUS). METHODS Six male patients who had extensive PUS extending from the bulbomembranous urethra to the bladder neck due to prostatic disease treatment and underwent transperineal BVA between 2014 and 2020 were retrospectively reviewed. BVA was performed according to the elaborate perineal approach for pelvic fracture urethral repair with minor modifications. After confirming the absence of recurrent stenosis 6 months postoperatively, the patients were offered artificial urinary sphincter (AUS) placement for subsequent urinary incontinence (UI). RESULTS Median patient age was 68, and the etiology of PUS was radical prostatectomy for prostate cancer in four patients, brachytherapy for prostate cancer in one, and transurethral resection of the prostate for benign prostatic hyperplasia in one. All patients had been previously treated with multiple transurethral procedures such as urethrotomy and dilation. Median operative time and blood loss were 211 min and 154 ml, respectively. Five cases (83.3%) had no recurrent stenosis with a median follow-up of 45 months, but a single direct vision internal urethrotomy was performed in one (16.7%) due to restenosis. Four (66.7%) patients underwent AUS placement via transcorporal approach for subsequent UI, but two had it removed due to urethral erosion. CONCLUSION Transperineal BVA could effectively manage extensive PUS after prostatic disease treatment. Staged AUS placement could be a viable option for subsequent UI, but the risk of urethral erosion seemed high.

Abstract
Objectives: To describe the use of a pedicled dartos flap between the pubic bone and bulbar urethra after elaborate perineal urethroplasty in complex pelvic fracture urethral distraction defect. This is to prevent the risk of entrapment of the anastomotic area within a fibrous scar and hence prevent the risk of urethral stricture recurrence. Our objective is also to theorise the entity of bulbar urethral entrapment to describe the trapping of the bulbar urethra by fibrosis after extensive bone resection in complex cases of pelvic fracture urethral distraction defect. Methods: Ten patients with complex pelvic fracture urethral distraction defect underwent perineal urethroplasty at our institution from 2017 to 2019. Urethroplasty was done using the elaborated perineal approach in the standard fashion. Pedicled fibrofatty tissue along with dartos from the scrotum was used to separate the site of urethral anastomosis from the bare pubic bone and fill the dead space. Results: All patients are asymptomatic with no stricture recurrence in follow-up. Conclusions: Vascularised pedicle flap should become an important tenant in the elaborated perineal repair of complex pelvic fracture urethral distraction defect. It provides an ideal option in this scenario by decreasing the risk of urethral stricture recurrence without adding morbidity and minimum extra operative time. Level of evidence: Not applicable.

Surgical and Patient-Reported Outcomes of Delayed Anastomotic Urethroplasty for Male Pelvic Fracture Urethral Injury at a Japanese Referral Center. J Clin Med 2022; 11:jcm11051225. [PMID: 35268315 PMCID: PMC8911321 DOI: 10.3390/jcm11051225] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2022] [Revised: 02/16/2022] [Accepted: 02/22/2022] [Indexed: 12/28/2022] Open
Abstract
We aimed to assess the surgical and patient-reported outcomes of delayed anastomotic urethroplasty (DAU) for pelvic fracture urethral injury (PFUI). We included 211 male patients who underwent DAU for PFUI. DAU success was considered when the urethral lumen was sufficiently large for the passage of a flexible cystoscope, without additional treatment required. The patients completed the lower urinary tract symptoms (LUTS)-related quality of life (QOL) questionnaire (scores: 0, not at all; 1, a little; 2, somewhat; 3, a lot), EuroQol-5 dimensions (EQ-5D), and EQ-5D visual analog scale (EQ-VAS). Postoperative overall satisfaction was evaluated using the following responses: “very satisfied,” “satisfied,” “unsatisfied,” or “very unsatisfied.” DAU was successful in 95.3% cases, with a median postoperative follow-up duration of 48 months. Multivariate logistic regression analysis revealed that “greater blood loss” was an independent predictor of failed urethroplasty. Questionnaire responses were obtained from 80.1% patients. The mean LUTS-related QOL, EQ-5D score and EQ-VAS improved significantly from 2.8, 0.63 and 54.4 at baseline to 0.9, 0.81 and 76.6 postoperatively (p < 0.0001 for all parameters). Moreover, 35.5% and 59.2% of the patients responded being “satisfied” and “very satisfied,” respectively, with their DAU outcomes. DAU not only had a high surgical success rate, but also a significant beneficial effect on both LUTS-related QOL and overall health-related QOL.

Abstract
The management of male pelvic fracture urethral injury remains a urological challenge. Pelvic fracture urethral injury can be associated with sequelae, such as urethral gap, erectile dysfunction and urinary incontinence. Delayed anastomotic urethroplasty, the gold standard treatment for urethral gaps caused by pelvic fracture urethral injuries, is technically demanding, and reconstructive urologists should preoperatively obtain as much detailed anatomical information as possible. A combination of antegrade and retrograde urethrography is the fundamental preoperative evaluation, but it cannot accurately assess the urethral gap length, the degree of lateral prostatic displacement, the anatomical relationship of the urethra with its surrounding structures (such as the rectum and dorsal venous complex) or periurethral problems (such as minor fistulae or cavitation). To make up for these limitations of urethrography, magnetic resonance imaging has emerged as a non-invasive, multiplanar and high-resolution modality for the evaluation of pelvic fracture urethral injury. Magnetic resonance imaging has excellent soft-tissue contrast, and can clearly show the urethra and periurethral tissues without the effects of radiation, thus enabling clinicians to anticipate the required ancillary techniques for delayed anastomotic urethroplasty and to predict functional outcomes, such as erectile function and urinary continence, after delayed anastomotic urethroplasty. This review discusses the role of magnetic resonance imaging in the evaluation of pelvic fracture urethral injury and its impact on patient management.

Abstract
OBJECTIVE To compare the long-term outcomes of initial management of pelvic fracture urethral injury (PFUI) in a large cohort of trauma patients undergoing urethral reconstruction. MATERIALS AND METHODS 119 patients underwent urethral reconstruction by a single surgeon for PFUI at our center between 1998-2018. We compared initial PFUI management - primary realignment vs suprapubic tube (SPT) insertion alone. Multivariable Cox proportional hazard analysis was used to assess the association between primary intervention and the risk of having a complication. RESULTS PFUI was initially managed with primary realignment (57%) or SPT alone (43%). Ultimately, all patients underwent a primary perineal urethral anastomosis after a median of 7 months (IQR: 5-14). Overall, 27 patients (23%) had 1 or more long-term complications after a median 25 months (IQR:7-66), including urethral stricture, de novo erectile dysfunction, and urinary incontinence. On multivariable analysis, initial PFUI management did not predict for complications. CONCLUSION No difference was found in long-term outcomes after urethral reconstruction when comparing initial PFUI management of primary realignment vs SPT insertion.

Abstract
PURPOSE We studied the impact of membranous urethral length (MUL) on magnetic resonance imaging (MRI) on post-urethroplasty continence in male patients with pelvic fracture urethral injury (PFUI). METHODS Of 169 male patients with PFUI who underwent delayed anastomotic urethroplasty between 2008 and 2020, 85 who underwent preoperative MRI, had no recurrent stenosis on cystoscopy, and underwent a 1-h pad test 1 year after surgery were included. MUL was defined as the distance from the distal end of the disrupted proximal urethra to the apex of the prostate, as measured using T2-weighted MRI. Urinary incontinence (UI) was defined as a 1-h pad test weight > 2.0 g. RESULTS None of the patients had UI before a pelvic fracture. Eighty-two patients (96.5%) had a measurable MUL, and the median length was 8.1 (interquartile range [IQR], 5.2-10.8) mm. The median weight of the 1-h pad test was 1.0 (IQR, 0.0-4.0) g, and 26 (30.6%) patients had UI. An open bladder neck (odds ratio [OR], 4.6; 95% confidence interval [CI], 1.0-22.0; p = 0.04) and a short measurable membranous urethra (for every extra mm: OR, 1.2; 95% CI, 1.0-1.3; p = 0.04) were significant UI predictors on multivariate analysis. CONCLUSIONS A long MUL is significantly positively associated with urinary continence in male patients with PFUI. This could be of potential value to reconstructive urologists when counseling patients regarding post-urethroplasty continence before urethroplasty.

Transperineal anastomotic urethroplasty for the treatment of pelvic fracture urethral distraction defects: a progressive surgical strategy. World J Urol 2021; 39:4435-4441.

Abstract
PURPOSE The aim was to reduce the difficulty of transperineal anastomotic urethroplasty for pelvic fracture urethral distraction defect (PFUDD) and make it easy to master through an effective strategy. PATIENTS AND METHODS Between January 2010 and December 2019, 1637 patients with PFUDDs were treated by transperineal anastomotic urethroplasty. The surgical strategy we used was the progressive transperineal anastomotic urethroplasty. First, after full mobilization of the distal bulbomembranous urethra, the stenotic urethra was transected directly at the proximal margin of the stenotic urethra to expose the proximal disrupted urethral end. Second, if the urethral stenosis location of some complicated cases was too deep to fully mobilize, the position of urethral transection was selected at the distal margin of the stenotic urethra. Then, the distal and proximal disrupted urethras were then trimmed and anastomosed without tension. A successful urethroplasty was defined as reestablishment of a uniform urethral caliber and no further interventions were needed. RESULTS Follow-up was obtained in 1475 patients. The success rate was 92.4% (1363/1475). Among the 112 failed patients, 10 patients received endoscopic urethrotomy, 99 underwent a secondary or third anastomotic urethroplasty and 3 successfully treated with perineal skin flap urethroplasty. After final successful urethroplasty, 125 patients (8.5%) had different degrees of urinary incontinence and 15 (1.6%) developed de novo erectile dysfunction (1.6%). CONCLUSION The progressive transperineal anastomotic urethroplasty strategy was effective for treating PFUDD cases, improving surgical efficacy and reducing complications. It may contribute to standardizing the transperineal anastomotic urethroplasty and making it easy to master.

Multi-institutional Outcomes and Associations After Excision and Primary Anastomosis for Radiotherapy-associated Bulbomembranous Urethral Stenoses Following Prostate Cancer Treatment. Urology 2021; 152:117-122.

Abstract
OBJECTIVE To evaluate the outcomes of excision and primary anastomosis (EPA) for radiation-associated bulbomembranous stenoses using a multi-institutional analysis. The treatment of radiation-associated urethral stenosis is typically complex owing to the adverse impact of radiation on adjacent tissue. METHODS An IRB-approved multi-institutional retrospective review was performed on patients who underwent EPA for bulbomembranous urethral stenosis following prostate radiotherapy. Preoperative patient demographics, operative technique, and postoperative outcomes were abstracted from 1/2007-6/2018. Success was defined as voiding per urethra without the need for endoscopic treatment and a minimum follow-up of 12 months. RESULTS One hundred and thirty-seven patients from 10 centers met study criteria with a mean age of 69.3 years (50-86), stenosis length of 2.3 cm (1-5) and an 86.9% (119/137) success rate at a mean follow-up 32.3 months (12-118). Univariate Cox regression analysis identified increasing patient age (P = .02), stricture length (P <.0001) and combined modality radiotherapy (P = .004) as factors associated with stricture recurrence while body mass index (P = .79), diabetes (P = .93), smoking (P = .62), failed endoscopic treatment (P = .08) and gracilis muscle use (P = .25) were not. On multivariate analysis, increasing patient age (H.R.1.09, 95%CI 1.01-1.16; P = .02) and stenosis length (H.R.2.62, 95%CI 1.49-4.60; P = .001) remained associated with recurrence. Subsequent artificial urinary sphincter was performed in 30 men (21.9%), of which 25 required a transcorporal cuff and 5 developed cuff erosion. CONCLUSIONS EPA for radiation-associated urethral stenosis effectively provides unobstructed instrumentation-free voiding. However, increasing stenosis length and age are independently associated with surgical failure. Patients should be counseled that further surgery for incontinence may be necessary.

Abstract
OBJECTIVE The urethral gap in pelvic fracture urethral injury (PFUI) is traditionally assessed using voiding cystourethrogram (VCUG) and retrograde urethrogram (RGU). Magnetic resonance imaging (MRI) is performed in complex cases. We assessed the refined "Joshi" MRI protocol to evaluate complex urethral defects after PFUI. MATERIAL AND METHODS A prospective study was conducted at our center from January 2018 to January 2020, involving patients aged >18 years with PFUI, suitable for MRI, and those who gave consent to perform standard RGU, VCUG, and MRI using standard and "Joshi" protocol. Forty men were included in the study. Distance between urethral/prostatic stumps was measured. Image quality was scored by four radiologists and four urologists. The surgical approach and type of PFUI repair were noted. We also established the need for inferior pubectomy by assessing the position of the posterior urethra (membranous) in relation to a horizontal line drawn from the lower edge of the pubic bone anteriorly to the rectum posteriorly in a sagittal image. RESULTS The mean age was 30 years (SD, 5.25; range, 21-43), and the time from injury to imaging was 4 months (3-10 months); 40% of the men underwent crural separation, 57.5%, inferior pubectomy, and 2.5%, crural rerouting. There was a difference of 0.3 to 1.1 cm in the urethral gap measurements between MR images using the standard versus "Joshi" technique. MRI identified complex injuries such as rectourethral fistula, the need for inferior pubectomy, and the orientation of the posterior urethra. Urologists' and radiologists' satisfaction scores for the MR images were satisfactory to excellent. If the posterior urethra was over the defined mark, there was a 100% likelihood of inferior pubectomy (23/40 patients). CONCLUSION MR image acquisition using the "Joshi" protocol provided high-quality anatomical information in PFUI cases to assist with surgical planning.

Abstract
OBJECTIVES Pubectomy is an ancillary technique used to increase exposure of the disrupted urethra and reduce anastomotic tension, which can be difficult for inexperienced surgeons. The objective of the present study was to illustrate the use of an air drill enabling delicate and precise bone resection in pubectomy for delayed anastomotic urethroplasty for pelvic fracture urethral injury. METHODS Between 2009 and 2019, 88 male patients underwent delayed anastomotic urethroplasty with pubectomy for pelvic fracture urethral injury. A total of 73 procedures used a high-speed surgical air drill (HiLAN HS; Aesculap, Tuttlingen, Germany) equipped with a short-hand piece. Operative time and blood loss in the air drill patient group (group 1) were compared with that of patients who underwent pubectomy using a rongeur and/or gouge (group 2, n = 15). RESULTS In 65 group 1 patients, urethroplasty was carried out using the perineal approach, with partial inferior pubectomy. Eight group 1 patients, whose proximal urethral end was displaced upward superior to the upper edge of pubis, underwent urethroplasty using the perineal and abdominal approach, with a superior partial pubectomy and supracrural urethral rerouting. No difficulty was encountered using the air drill in any of the cases. There was no significant difference in median operative time between the groups (group 1 256 min vs group 2 228 min; P = 0.31). The median blood loss in group 1 was significantly lower than group 2 (149 mL vs 453 mL; P < 0.0001). CONCLUSIONS Surgical air drills might facilitate pubectomy in patients undergoing delayed anastomotic urethroplasty for pelvic fracture urethral injury. This tool offers the advantage of a delicate bone resection with reduced blood loss.

Abstract
Background: Urethral stricture disease (USD) represents a complex urological problem. Urethroplasty is considered the gold standard for the treatment of USD. Most available studies report outcome data obtained from retrograde urethrography and uroflowmetry. Only a limited number of papers describe the effect of urethroplasty on erectile function and their results are inconsistent. The goal of this prospective study was to evaluate the effect of urethroplasty on both lower urinary tract and erectile function using objective parameters and standardized patient-reported outcome measurement tools.Materials and Methods: A total of 55 consecutive patients with USD were enrolled into the study. Patients underwent ventral onlay urethroplasty, urethroplasty according to the Asopa technique, dorsal onlay urethroplasty, cutaneous flap urethroplasty using the Orandi technique or anastomotic repair. All patients were evaluated using uroflowmetry, urethrography, the PROM-USS questionnaire and the International Index of Erectile Function-5 questionnaire (IIEF-5) pre-operatively and consequently post-op, in 3-month intervals. This study presents the comparison of baseline pre-op parameters and parameters 12 months after the surgery using the Wilcoxon signed rank test, Wilcoxon rank sum test and the Kruskal-Wallis one-way analysis of variance.Results: A significant improvement in uroflowmetry parameters, all domains of the PROM-USS questionnaire, as well as the overall score of the IIEF-5 was observed. No statistically significant differences between sub-groups were found when comparing treatment results in patients with short versus long strictures and patients with penile urethra stricture versus bulbar or membranous urethra stricture.Conclusions: Urethroplasty yielded very good functional results with respect to both lower urinary tract and erectile functions.

Management of pelvic fracture urethral injuries in the developing world. World J Urol 2019; 38:3027-3034. [PMID: 31468131 DOI: 10.1007/s00345-019-02918-0] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2019] [Accepted: 08/20/2019] [Indexed: 10/26/2022] Open
Abstract
INTRODUCTION Pelvic fracture causes urethral injury in about 10% of patients. The etiology of injury is different in developing and developed world. While high-velocity automobile accidents are common in developed countries, where patients are in the car and there is usually a side impact, in the developing world, significant number of injuries are caused by two-wheeler accidents, pedestrians, farming accidents, fall from height, fall from tractor, fall from tree, and other causes like earthquake. We share our experience which is the largest in the reported literature. MATERIALS AND METHODS In our tertiary referral center, we get referrals from all across the globe. Since 1995 till 2018 we have performed 1307 surgeries for Pelvic fracture urethral injury. Our referrals are for complex urethroplasty. Our data from 1995-2018 was analyzed. Data after June 2018 was not included so as to have a minimum follow up of 6 months. RESULTS 1296 patients were males and 11 were females. In the group of 1296 males, mean age was 32.4 years (range 1-79 years). The minimum follow-up was 6 months, and the median follow-up was 56.7 months (range 6.2-233.7). The overall success rate was 88.79% for primary cases while re-do urethroplasty patients had a success rate of 83.70%. The majority of our patients (more than 61.40%) needed inferior pubectomy: Of the total 1307 cases of urethroplasty for pelvic fracture urethral injury data was available for 1042 patients. Data were available for 1042 patients. The data from 2012 onwards were prospectively analyzed while the previous data were retrospectively analyzed. CONCLUSION PFUI are common in the developing world. They tend to be more complex and have longer gaps as compared to developed world. This could be related to the anthropometric differences between races as well as nature of injury. They are best managed with delayed transperineal repair with excellent outcomes. Ancillary maneuvers are more frequently required. Re-do urethroplasty can achieve good results.

Abstract
Pelvic fracture urethral distraction defects (PFUDDs) are relatively infrequent in boys, and treatment for PFUDDs presents one of the most difficult problems in urological practice. Anastomotic urethroplasty is considered an ideal surgical procedure for PFUDDs in boys. However, various surgical approaches for anastomotic urethroplasty have been proposed, including a simple transperineal approach, a transperineal intercorporal septal separation approach, a transperineal inferior pubic approach, and a combined transpubic-perineal approach. This study aims to determine which surgical approach is best for PFUDDs in boys. We retrospectively identified 22 boys with PFUDDs aged 2-14 years who underwent anastomotic urethroplasty via different approaches between January 2008 and December 2017. Follow-up was performed in all the 22 patients for 6-123 (mean: 52.0) months. Finally, 20 of the 22 boys (90.9%) were successfully treated, including 1 of 2 patients treated with a simple transperineal approach, 3 of 3 with a transperineal approach with intercorporal septal separation, 14 of 15 with a transperineal inferior pubic approach, and 2 of 2 with a combined transpubic-perineal approach. Two patients had failed outcomes after the operation, and stenosis recurred. Based on the outcome of the 22 patients, we can draw a preliminary conclusion that most boys (20/22) can be treated with a transperineal inferior pubic approach or simpler procedures without the need of completely removing or incising the pubis. The combined transpubic-perineal approach can be used in cases of extremely long urethral distract defects.

Abstract
Pelvic fractures from high-energy blunt force trauma can cause injury to the posterior urethra, known as pelvic fracture urethral injury, which is most commonly associated with unstable pelvic fractures. Pelvic fracture urethral injury should be suspected if a patient with pelvic trauma has blood at the meatus and/or difficulty voiding, and retrograde urethrography should be carried out if the patient is stable. Once urethral injury is confirmed, urinary drainage should be established promptly by placement of a suprapubic tube or primary realignment of the urethra over a urethral catheter. Although pelvic fracture urethral injury is accompanied by subsequent urethral stenosis in a high rate and it has been believed that primary realignment can reduce the risk of developing urethra stenosis, it also has a risk of complicating stenosis and its clinical significance remains controversial. Once inflammation and fibrosis have stabilized (generally at least 3 months after the trauma), the optimal management for the resulting urethral stenosis is delayed urethroplasty. Delayed urethroplasty can be carried out via a perineal approach using four ancillary techniques in steps (bulbar urethral mobilization, corporal separation, inferior pubectomy and urethral rerouting). Although pelvic trauma can impair continence mechanisms, the continence after repair of pelvic fracture urethral injury is reportedly adequate. Because erectile dysfunction is frequently encountered after pelvic fracture urethral injury and most patients are young with a significant life expectancy, its appropriate management can greatly improve quality of life. In the present article, the key factors in the management of pelvic fracture urethral injury are reviewed and current topics are summarized.

Abstract
Background: Management of partial or complete traumatic urethral disruptions of the posterior urethra in children and adolescents, secondary to pelvic fracture poses a challenge. Controversy exists as to the correct acute treatment of posterior urethral injuries and delayed management of PFPUDDs. We reviewed the urological literature related to the treatment of traumatic posterior urethral injuries and delayed repair of these distraction defects in children and adolescents. Material and Methods: There are few long-term outcomes studies of patients who underwent PFPUDDs repairs in childhood; most reports included few cases with short follow up. We excluded studies in which the cohort of patients was heterogeneous in terms of stricture disease, etiology and location. Results: Primary cystostomy and delayed urethroplasty is the traditional management for PFPUIs. Immediate repair is rarely possible to perform. Realignment of posterior urethral rupture in children is indicated in special situations: (a) concomitant bladder neck tears, (b) associated rectal lacerations, (c) long disruptions of the urethral ends. Before delayed reconstruction ascending urethrography and micturating cystourethrogram along with retrograde and antegrade urethroscopy define site and length of the urethral gap. However, the most accurate evaluation of the characteristics of the distraction defect is made when surgical exposure reveals the complexity of the ruptured urethra. Partial ruptures may be managed with urethral stenting or suprapubic cystostomy, which may result in a patent urethra or a short stricture treated by optical urethrotomy. The gold standard treatment for PFPUDDs in children is deferred excision of pelvic fibrosis and bulbo-prostatic tension-free anastomosis, provided a healthy anterior urethra is present. Timing of delayed repair is at 3 to 4 months after trauma. Some urologists prefer either the perineal access or the transpubic approach to restore urethral continuity in children with PFPUDDs. Substitution urethroplasties are used in children with PFPUDDs, when anastomotic repair can't be achieved due to severe damage of the bulbar urethra. Conclusion: As evidenced in this review the progressive perineo-abdominal partial transpubic anastomotic repair has advantages over the isolated perineal anastomotic approach in patients with "complex" PFPUDD. This approach provides wider exposure and facilitates reconstruction of long or complicated posterior urethral distraction defects.

Abstract
Blunt trauma to the lower urinary tract is usually associated with pelvic fractures. The European Association of Urology (EAU) provides guidelines to diagnose and treat these injuries. The guidelines summarise the available evidence and provide recommendations on diagnosis and treatment of these patients. Therefore, these guidelines are important adjuncts to the urologist and emergency physician in the clinical decision-making. However, strict adherence to the guidelines is not always easy or possible because of concomitant injuries obscuring the clinical picture. This is illustrated by two case reports of concomitant injuries of the lower urinary tract (bladder with urethral injury). The clinical decisions will be discussed point by point and should serve as a practical teaching moment for the reader.

Abstract
OBJECTIVE The management of recurrent posterior urethral strictures developing after pelvic fracture urethral injury (PFUI) is a challenging task. Despite availability of many surgical approaches, there is no consensus regarding the optimal approach. The objective of this study was to present our 10-year experience in the management of recurrent urethral strictures due to PFUI. MATERIAL AND METHODS We did a retrospective single-institution review of patients who underwent surgical management for recurrent posterior urethral strictures from January 2006 to December 2016 using descriptive statistics. We included only those patients with PFUI who underwent some definitive surgical procedure for their previous failed repair(s). RESULTS The final analysis included data of 50 male patients (10 adolescents and 40 adults). Mean age of the patients was 29.92±10.62 years. The average length of stricture was 3.02±1.47 cm. Progressive perineal urethroplasty (PPU) was done in 40 cases. Two patients with concomitant rectourethral fistula/false passage underwent transpubic urethroplasty (TPU). Three patients with complete bulbar necrosis were managed with single stage/staged preputial tube reconstruction. One patient underwent microsurgical urethroplasty using radial free forearm flap while in two patients each Mitrofanoff appendicovesicostomy and perineal urethrostomy was done. Majority of complications were minor (Clavien Grade 1 and 2). Overall success rate of PPU was 75%. Mean follow-up period was 29.46±10.68 months (range: 13-60 months). CONCLUSION Most cases of recurrent posterior urethral strictures of <3 cm in length can be operated by PPU with reasonable success rates. Complex and long-segment (higher than 3 cm) strictures require use of ancillary procedures like TPU, substitution urethroplasty and Mitrofanoff appendicovescostomy.

Abstract
Given its complex anatomy, injury to the posterior urethra may result in a number of reconstructive challenges. With the appropriate operative planning and experience, surgical repair can be very successful. This review discusses the applicable techniques for the perineal approach to posterior urethral stenosis, including bulbomembranous anastomosis for pelvic fracture urethral injury and repair of vesicourethral anastomotic stenosis (VUAS) following prostate surgery. The advanced techniques reviewed include an adaptation allowing a bulbar artery sparing approach to posterior urethroplasty and an intrasphincteric urethroplasty procedure which may allow continence preservation in patients with membranous urethral stenosis.

Abstract
Purpose We present our success rate and complications of delayed anastomotic urethroplasty (DAU) in patients with post-traumatic posterior urethral injury. Materials and Methods This was a retrospective study of patients aged ≥17 years that underwent DAU for post-traumatic posterior urethral injury during 2010-2014. Stricture length was measured by ascending and descending urethrogram. Success of procedure was considered when the patient was free of stricture-ralated obstruction and needed no further intervention. Primary group includes patients who underwent first time delayed urethroplasty while secondary group included patients who had some sort of urethral manipulation in local hospital. Results were analyzed using unpaired t-test, Chi-square test, binary logistic regression, Kaplan-Meier curves, and log-rank test. Results Of the 80 male patients, 73 (91.25%) patients underwent primary DAU while 7 (8.75%) patients had secondary DAU. Median age, stricture length, and follow-up were 27.0 ± 12.7, 1.6 ± 0.9, and 3.2 ± 0.9, respectively. Overall, success rate was 83.75% while success rate in primary group was 89.04% and secondary group was only 28.57% (P = 0.0059). Regarding ancillary maneuvers, urethral mobilization alone was done in 29 (36.25%) patients with success rate (72.41%), corporeal body separation in 36 (45%) patients with success rate (91.66%), inferior wedge pubectomy in 13 (16.25%) with success rate (84.61%), supracrural rerouting in 1 (1.25%) with success rate (100%), and abdominoperineal approach in 1 (1.25%) with success rate of 100% (P = 0.193). Patients who had prior urethral manipulation affect the outcome of definitive anastomotic urethroplasty. Conclusion DAU has durable success rate with less morbidity. Ancillary elaborated maneuvers are frequently needed in patients with complex and elongated post-traumatic posterior urethral defect with successful outcome.

Abstract
PURPOSE OF REVIEW Due to the proximity of the rhabdosphincter and cavernous nerves to the membranous urethra, reconstruction of membranous urethral stricture implies a risk of urinary incontinence and erectile dysfunction. To avoid these complications, endoscopic management of membranous urethral strictures is traditionally favored, and bulboprostatic anastomosis is reserved as the main classical approach for open reconstruction of recalcitrant membranous urethral stricture. The preference for the anastomotic urethroplasty among reconstructive urologists is likely influenced by the familiarity and experience with trauma-related injuries. We review the literature focusing on the anatomy of membranous urethra and on the evolution of treatments for membranous urethral strictures. RECENT FINDINGS Non-traumatic strictures affecting bulbomembranous urethra are typically sequelae of instrumentation, transurethral resection of the prostate, prostate cancer treatment, and pelvic irradiation. Being a different entity from trauma-related injuries where urethra is not in continuity, a new understanding of membranous urethral anatomy is necessary for the development of novel reconstruction techniques. Although efficacious and durable to achieve urethral patency, classical bulboprostatic anastomosis carries a risk of de-novo incontinence and impotence. Newer and relatively less invasive reconstructive alternatives include bulbar vessel-sparing intra-sphincteric bulboprostatic anastomosis and buccal mucosa graft augmented membranous urethroplasty techniques. The accumulated experience with these techniques is relatively scarce, but several published series present promising results. These approaches are especially indicated in patients with previous transurethral resection of the prostate in which sparing of rhabdosphincter and the cavernous nerves is important in attempt to preserve continence and potency. Additionally, introduction of buccal mucosa onlay grafts could be especially beneficial in radiation-induced strictures to avoid transection of the sphincter in continent patients, and to preserve the blood supply to the urethra for incontinent patients who will require artificial urinary sphincter placement. The evidence regarding erectile functional outcomes is less solid and this item should be furtherly investigated.

Abstract
Pelvic fracture urethral injury (PFUI) management in male adults and children is controversial. The jury is still out on the best way to manage these injuries in the short and long-term to minimise complications and optimise outcomes. There is also little in the urological literature about pelvic fractures themselves, their causes, grading systems, associated injuries and the mechanism of PFUI. A review of pelvic fracture and male PFUI literature since 1757 was performed to determine pelvic fracture classification, associated injuries and, PFUI classification and management. The outcomes of; suprapubic catheter (SPC) insertion alone, primary open surgical repair (POSR), delayed primary open surgical repair (DPOSR), primary open realignment (POR), primary endoscopic realignment (PER), delayed endoscopic treatment (DET) and delayed urethroplasty (DU) in male adults and children in all major series have been reviewed and collated for rates of restricture (RS), erectile dysfunction (ED) and urinary incontinence (UI). For SPC, POSR, DPOSR, POR, PER, DET and DU; (I) mean RS rate was 97.9%, 53.9%, 18%, 58.3%, 62.0%, 80.2%, 14.4%; (II) mean ED rate was 25.6%, 22.5%, 71%, 37.2%, 23.6%, 31.9%, 12.7%; (III) mean UI rate was 6.7%, 13.6%, 0%, 14.5%, 4.1%, 4.1%, 6.8%; (IV) mean FU in months was 46.3, 29.4, 12, 61, 31.4, 31.8, 54.9. For males with PFUI restricture and new onset ED is lowest following DU whilst UI is lowest following DPOSR. On balance DU offers the best overall outcomes and should be the treatment of choice for PFUI.

Abstract
Urethral stricture disease is increasingly common occurring in about 1% of males over the age of 55. The stricture tissue is rich in myofibroblasts and multi-nucleated giant cells which are thought to be related to stricture formation and collagen synthesis. An increase in collagen is associated with the loss of the normal vasculature of the normal urethra. The actual incidence differs based on worldwide populations, geography, and income. The stricture aetiology, location, length and patient's age and comorbidity are important in deciding the course of treatment. In this review we aim to summarise the existing knowledge of the aetiology of urethral strictures, review current treatment regimens, and present the challenges of using tissue-engineered buccal mucosa (TEBM) to repair scarring of the urethra. In asking this question we are also mindful that recurrent fibrosis occurs in other tissues-how can we learn from these other pathologies?

Abstract
Posterior urethral injuries typically arise in the context of a pelvic fracture. Retrograde urethrography is the preferred diagnostic test in trauma patients with pelvic fracture where a posterior urethral rupture is suspected. Pelvic fractures however preclude the adequate positioning of the patient on the X-ray table on admission and computed tomography scan with intravenous contrast and delayed films generally performed first. Suprapubic bladder catheter placement under ultrasound guidance should be performed whenever a posterior urethral disruption is suspected. Early diagnosis and proper acute management decrease the associated complications, such as strictures, urinary incontinence and erectile dysfunction. The correct and appropriate initial treatment of associated urethral rupture is critical to the proper healing of the injury. Placing of a suprapubic cystostomy on admission and delayed anastomotic urethroplasty after 3–6 months continues to be the gold standard of treatment. In this paper, we provide a comprehensive review of the literature with a special emphasis on the various treatments available: Open or endoscopic primary realignment, immediate or delayed urethroplasty after suprapubic cystostomy, and delayed optical urethrotomy.

Abstract
BACKGROUND Post-traumatic posterior urethral injuries in children are rare events. Their management algorithms are extrapolations from adult literature and they continue to pose a difficult challenge for pediatric urologists. Not much data for age-related feasibility of an end-to-end urethroplasty are available. OBJECTIVE This study was designed to validate a simple preoperative radiographic score to predict the type of surgical repair for traumatic posterior urethral strictures in children. MATERIALS AND METHODS This retrospective study was conducted in a tertiary care center in northern India between 2000 and 2015. All patients under 15 years with traumatic bulboprostatic stricture disease were included. Preoperative voiding cystourethrogam (VCUG) and retrograde urethrogram (RGU) films were used to calculate the gapometry index (G/U index), defined as the length of urethral gap divided by the bulbar urethral length. This index was then analyzed for two patient groups based on the anatomical approach employed for achieving an end-to-end urethroplasty: group 1, who underwent a simple perineal approach, and group 2, who needed a more elaborate procedure. Statistical analysis was performed with the two-tailed t-test with SPSS version 18. RESULTS A total of 38 patients met the inclusion criteria. The age distribution and G/U index for both groups are detailed in the table. The difference in mean length of the urethral gap for both groups was statistically significant (2.1 cm in group 1 vs. 3.6 cm in group 2). There was a direct correlation between the complexity of surgical procedure required to bridge the urethral gap and the G/U index. The overall success for urethroplasty in either group was between 92.3% and 94.6%. DISCUSSION Urethral extensibility is more suitable for younger children. This challenges the traditional viewpoint that the transpubic approach for urethroplasty is more favorable in children. No previous study has been cited in literature correlating the gapometry index with the surgical approach for posterior urethral defects. Our results reflect that a preoperative G/U index of 0.44 correlate with a simple perineal repair, whereas an index of above 0.87 indicates the likelihood of needing a more elaborate transpubic approach. CONCLUSIONS Preoperative assessment of G/U index in children with traumatic posterior urethral injuries can successfully predict the operative approach and may therefore aid in better management of these patients.

Abstract
Although posterior urethral injury occurs almost always in association with pelvic fracture, it may result from severe trauma to the perineum with its associated potential lethality and severe morbidity. Early primary endoscopic realignment over a urethral catheter can be attempted, although an immediate suprapubic tube placement remains the standard of care. Definitive treatment consists of elective open posterior anastomotic urethroplasty through a perineal approach. The authors present a 53-year-old man who sustained total, massive perineal destruction resulting from work accident with an agricultural implement. Immediate suprapubic tube placement was performed followed by delayed elective transperineal anastomotic posterior urethroplasty. A major multidisciplinary approach was necessary in the management strategy, including orthopedic, general, plastic, vascular surgeries, and reconstructive urology teams. At a later stage, with the patient stabilized and recovered from major, life-threatening lesions dealt with by a multidisciplinary team, urethral reconstruction can be undertaken with ultimate good functional outcomes.

Predictors for success of internal urethrotomy in patients with urethral contracture following perineal repair of pelvic fracture urethral injuries. Injury 2017; 48:1035-1039.

Abstract
INTRODUCTION Internal urethrotomy (IU) in patients with urethral contracture following perineal repair of pelvic fracture urethral injuries (PRPFUI) is troublesome. We evaluated the clinical factors affecting the surgical outcome of IU for urethral contracture after PRPFUI. MATERIALS AND METHODS We retrospectively reviewed the records of 35 patients who underwent IU for urethral contracture after PRPFUI between March 2004 and June 2013. Ages of patients ranged from 18 to 50, and their follow-up duration was more than 1year after IU. The urethral contracture was confirmed by retrograde urethrogram or cysto-urethroscopy. Success was defined as greater than 15mL/s of peak urinary flow rate at 1year after IU without any clinical evidence of urethral contracture. Success rates were investigated according to the number of IU. Age, body mass index, urethral defect length before PRPFUI, time interval between the original urethral injury and the PRPFUI or between a previous operation and the PRPFUI, time interval between the PRPFUI and the urethral contracture, number of PRPFUI performed, and the type of urethral lengthening procedure were compared between patients with and without success according to the number of IU. RESULTS Among the 35 patients, the overall success rate of IU was 37% (13/35) during the mean follow-up period of 53 months (range: 17-148 months). There were 8 and 5 patients with success in first and second IU, respectively. However, there was no success after third IU. Urethral defect length before PRPFUI was significantly shorter in patients with success who underwent first and second IU (p<0.05). There were significant differences of success between patients with and without previous repeated failures of PRPFUI in first and second IU (p<0.05). CONCLUSIONS Short urethral defect length and no previous surgical failures before PRPFUI are good prognostic factors for IU following PRPFUI. Only one or two IUs will be helpful in patients with urethral contracture following PRPFUI.

Abstract
INTRODUCTION The posterior urethral lesions are associated with pelvis fractures in 5-10% of cases. The posterior urethra is attached to the pelvis bone by puboprostatic ligaments and the perineal membrane, which explains why disruption of the pelvic ring can injure the urethra at this level. OBJECTIVES To identify suspected cases of posterior urethral trauma and to perform the diagnosis and its immediate or deferred management. ACQUISITION OF EVIDENCE Search in PubMed of articles related to traumatic posterior urethral lesions, written in English or Spanish. We reviewed the relevant publications including literature reviews and chapters from books related to the topic. SYNTHESIS OF THE EVIDENCE With patients with pelvis fractures, we must always rule out posterior urethral lesions. The diagnostic examination of choice is retrograde urethrography, which, along with the severity of the condition, will determine the management in the acute phase and whether the treatment will be performed immediately or deferred. Early diagnosis and proper acute management decrease the associated complications, such as strictures, urinary incontinence and erectile dysfunction. CONCLUSIONS Despite the classical association between posterior urethral lesions and pelvic fractures, the management of those lesions (whether immediate or deferred) remains controversial. Thanks to the growing interest in urethral disease, there are an increasing number of studies that help us achieve better management of these lesions.

Abstract
Current literature remains controversial regarding whether to treat patients sustaining pelvic fracture urethral injuries (PFUIs) with primary endoscopic realignment (PER) versus suprapubic tube (SPT) placement alone with elective bulbomembranous anastomotic urethroplasty (BMAU). Success rates for PER following PFUI are wide-ranging, depending on various authors’ definitions of what defines a successful outcome. At our institution, for SPT/BMAU patients, the mean time to definitive resolution of stenosis was dramatically shorter compared to PER cases. The vast majority of PER patients required multiple endoscopic urethral interventions and/or experienced various other adverse events which were rarely noted among the SPT/BMAU group. While PER does occasionally result in urethral patency without the need for further intervention, the risk of delay in definitive treatment and potential for adverse events has led to a preference for SPT and elective BMAU at our institution.

Abstract
OBJECTIVE To present a novel reconstruction technique for patients with pelvic fracture urethral injuries (PFUI) with bulbar artery sparing. MATERIALS AND METHODS We modified the traditional technique for PFUI reconstruction to preserve the proximal arterial inflow to the bulb. Since 2008, 26 consecutive patients have undergone this technique at our institution. The bulbar arteries are located using a Doppler ultrasound stethoscope and then the bulb is mobilized from one side only, without detachment from the perineum. The artery from that side is sacrificed to preserve the contralateral one; sometimes both arteries can be spared. Removal of the scar and end-to-end anastomosis is performed as usual. Successful arterial preservation was verified by postanastomosis Doppler auscultation. RESULTS Mean age was 37 years (15 to 70). Median time from trauma to urethral reconstruction was 11 weeks and mean stenosis length was 2.3 cm (1 to 4.5 cm). The left bulbar artery was preserved in 14 cases, the right in 4, and both arteries were spared in seven; an accidental injury of the artery to be preserved occurred in the remaining case. At a mean follow-up of 20 months (2-69), all patients are voiding normally stricture free. CONCLUSION Preservation of proximal arterial blood supply to the bulb during PFUI reconstruction is feasible and safe. A well-perfused reconstruction should heal better and theoretically our technique may avoid ischemic failure of the urethroplasty. A larger series and replication of our results in other centers are necessary to validate our technique's potential benefits.

Abstract
Purpose: One-stage anastomotic urethroplasty is an attractive procedure for reconstructing the urethra following trauma. This prospective study highlights the advantages of the procedure and outcome of treatment. Materials and Methods: A total of 87 patients, age range 11–68 years with a mean of 35.4 years were included in the study. These patients were seen at two tertiary Institutions in South East Nigeria. The stricture lengths varied between 0.8 cm and 3.2 cm. All had suprapubic cystostomy initially followed by an end to end perineal anastomosis after thorough work up. Preoperatively 9 (10.3%) patients had impotence from the trauma. Postoperatively the patients were assessed with peri-catheter retrograde urethrogram, micturating cystourethrogram, and uroflowmetery. Results: All the patients were males. At 6 months, 13 out of 21 (62%) patients who had bulbo-prostatic anastomosis and 62 out of 66 (94%) patients that had bulbo-membranous, bulbo-bulbar anastomosis had satisfactory micturition with urine flow rate >15 ml/s. Totally, 12 (13.8%) patients had urine flow rate of <12 ml/s. At 1-year, there were 12 re-strictures, no urinary incontinence and four cases of a decrease in the strength of penile erection that needed no treatment. Conclusion: Delayed one-stage anastomotic urethroplasty provides for decreased incidence of postoperative morbidity, re-stricture, impotence and urinary incontinence for most short segment posttraumatic urethral strictures.

Abstract
Pelvic fracture urethral injuries comprise one of the most challenging reconstructive procedures in urology. The obliterated or stenosed urethra can usually be effectively repaired by an end-to-end anastomosis (bulbomembranous anastomosis). To achieve this, a progression of surgical steps can be used to make a tension-free anastomosis. Before undertaking surgery it is important to comprehensively assess the patient to define their anatomical defects, in particular the site of the stenosis, the length of the distraction injury and the integrity of the bladder neck, and thus guide preoperative decision-making. Contemporary reports suggest that most pelvic fracture urethral distraction defects (PFUDD) can be adequately managed by a perineal approach. Nevertheless it is essential that all surgeons treating these injuries are familiar with the whole spectrum of operative steps that are necessary to repair PFUDD.
