Purpose: To investigate the etiology and management of male iatrogenic urethral stricture in China. Methods: The data of 172 patients with iatrogenic urethral stricture who underwent treatment at a high volume reference center in China from January 2008 to February 2014 were analyzed retrospectively. Databases were analyzed to understand the impact of different types of iatrogenic injury on stricture location, length and treatment of urethral strictures, as well as success rates. Results: The most common type of iatrogenic stricture was urethral instrumentations in 80 patients (46.51%). Mean stricture length was 3.3 ± 2.54 cm and the longest strictures were those caused by intravesical instillation. Substitution urethroplasty was the most common intervention and was performed in 60.47% (104/172) of patients. The overall success rate was 85.00% (136/160). Univariable analyses revealed that the type of iatrogenic injury was significantly related to restenosis (p = 0.036), and it is more apt to postoperative restenosis in the type of intravesical instillation than others. Conclusion: Our results showed that urethral instrumentation is the most common etiology of iatrogenic urethral stricture, and most iatrogenic urethral strictures involve the anterior urethra. The different etiologies are closely associated with stricture location, length and the overall prognosis of urethral strictures.

Objective To describe the complications of transperineal end-to-end anastomotic urethroplasty in patients with posterior urethral strictures resulting from pelvic fracture. Materials and Methods A total of 573 patients, who underwent bulboprostatic anastomosis for posterior urethral strictures, were enrolled in this study. Distraction defects were measured using retrograde urethrography combined with voiding cysto-urethrography. All patients underwent perineal excision and primary anastomotic urethroplasty. The urethroplasty was considered successful if the patient was free of stricture-related obstruction and did not require any further intervention. The degree of stress incontinence was assessed daily by pad testing. The prevalence of pre- and postoperative sexual disorders was investigated using the International Index of Erectile Function-5 questionnaire. Results Of 573 bulboprostatic anastomosis procedures performed, 504 (88%) were successful and 69 (12%) were not successful. The mean (sd) maximum urinary flow rate, assessed by uroflowmetry 4 weeks after surgery, was 20.52 (5.1) mL/s. Intraoperative rectal injury was repaired primarily in 28 cases. Recurrence of urethral strictures was observed in 10 (1.7%) patients during the first 6 months after surgery, and in 45 patients from 6 months to 1 year. All of these patients underwent re-operation. Twenty-four (4.2%) patients had mild urge incontinence and 28 (4.9%) had mild stress incontinence. Erectile dysfunction (ED) was present in two ( 0.05). Nine (1%) patients were found to have false passage between the posterior urethra and bladder neck. Conclusion The majority of complications associated with transperineal bulboprostatic anastomosis can be avoided as long as meticulous preoperative evaluation to define the anatomy and careful intra-operative manipulation are ensured.

Background Female urethral injury is rare, and there is no accepted standard approach for the repair of urethral strictures. Objective To evaluate the efficacy of transpubic access using pedicle tubularized labial urethroplasty for urethral reconstruction in female patients with urethral obliterative strictures and urethrovaginal fistulas. Design, setting, and participants Between January 1996 and December 2006, eight cases of female urethral strictures associated with urethrovaginal fistulas were treated using pedicle labial skin flaps. Interventions A flap of approximately 3×3.5×3cm of the labia minora or majora with its vascular pedicle was tubularized over an 18–22 Fr fenestrated silicone stent to create a neourethra. This technique was used in five women. Two flaps, approximately 1.5–3.5cm, were taken from bilateral labia minora or majora and were pieced together to create a neourethra. This technique was used in three patients. Measurements We performed voiding cystourethrography and uroflowmetry to assess postoperative results. Results and limitations The patients were followed up for 10–118 mo (mean 48.25 mo) after the procedure. There were no postoperative complications. Two patients complained of dysuria, which resolved spontaneously after 2 wk. One patient experienced stress incontinence that resolved after 4 wk. At 3-mo follow-up, one patient complained of difficulty voiding; the urinary peak flow was 13ml/s, and the patient was treated successfully with urethral dilation. All other patients had normal micturition following catheter removal. Conclusions Pedicle labial urethroplasty is a reliable technique for the repair of extensive urethral damage, and a transpubic surgical approach provides wide and excellent exposure for the management of complex obliterative urethral strictures and urethrovaginal fistulas secondary to pelvic fracture.

Background Urethrorectal fistulas (URF) in patients with complex posterior urethral strictures are rare and difficult to repair surgically. There is no widely accepted standard approach described in the published literature. Objective The aim of this study was to describe the outcomes of various operative approaches for the repair of URFs in patients with complex posterior urethral strictures. Design, setting, and participants From January 1985 to December 2007, 31 patients (age: 6–61 yr; mean: 28.4) with URFs secondary to posterior urethral strictures were treated using a perineal or combined abdominal transpubic–perineal approach. Interventions A simple perineal approach was used in 4 patients; a transperineal inferior pubectomy approach was used in 18 patients; and a combined transpubic–perineal approach was used in 9 patients. A bulbospongiosus muscle and subcutaneous dartos pedicle flaps were interposed between the repaired rectum and urethra in 22 patients. The combined transpubic–perineal approach used either a gracilis muscle flap (one patient) or a rectus muscle flap (eight patients). Measurements Suprapubic catheterisation was used for bladder drainage, and a urethral silicone stent was left indwelling for 4 wk. Results and limitations One-stage repair was successful in 4 patients (100%) using the perineal approach, in 16 of 18 patients (88.9%) using the transperineal–inferior pubectomy approach, and in 7 of 9 patients (77.8%) using the transpubic–perineal approach. Recurrent urethral strictures developed in two cases; one patient required regular dilation, and the other patient was treated successfully with tubed perineoscrotal flap urethroplasty. Recurrent URFs developed in two additional patients. Conclusions Surgical approaches for the treatment of URFs associated with complex urethral strictures should be based on a number of considerations including the location of the URF, its aetiology, the length of the urethral strictures, and a history of previous unsuccessful repairs. These results demonstrate that the transperineal–inferior pubic approach may be appropriate as a first-line procedure.

To develope a tree analysis pattern of mass spectral urine profiles to discriminate bladder transitional cell carcinoma (TCC) from non-cancer lesions using surface-enhanced laser desorption and ionization time-of-flight mass spectrometry (SELDI-TOF-MS) technology.Urine samples from 61 bladder transitional cell carcinoma (TCCs) patients, 53 healthy volunteers and 42 patients with other urogenital diseases were analyzed using IMAC-Cu-3 ProteinChip. Proteomic spectra were generated by SELDI-TOF- MS. A preliminary "training" set of spectra derived from analysis of urine from 46 TCC patients, 32 patients with benign urogenital diseases (BUD), and 40 age-matched unaffected healthy men were used to train and develop a decision tree classification algorithm which identified a fine-protein mass pattern that discriminated cancers from non-cancers effectively. A blinded test set including 38 cases was used to determine the sensitivity and specificity of the classification system.The algorithm identified a cluster pattern that, in the training set, segregated cancer from non-cancer with a sensitivity of 84.8% and specificity of 91.7%. The discriminatory pattern was correctly identified. A sensitivity of 93.3% and a specificity of 87% for the blinded test were obtained when compared the TCC versus non-cancers.SELDI-TOF-MS technology is a rapid, convenient and high-throughput analyzing method. The urine tree analysis proteomic pattern as a screening tool is effective for differential diagnosis of bladder cancer. More detailed studies are needed to further evaluate the clinical value of this pattern.

To evaluate the various operative details of strictures of the posterior urethra that are essential for a successful result.The clinical data of 191 patients with posterior urethral strictures or distraction defects from January 1990 to January 2006 were analyzed retrospectively. All patients underwent a retrograde and voiding urethrogram, 62 patients had urethral ultrasonography, 48 patients had urethroscopy, 3 patients had MRI. Repair was performed with a simple anastomosis after urethral mobilization in 66 patients, separation of the corporeal bodies in 48 patients, separation of the corporeal bodies and inferior pubectomy in 30 patients, transpubic anastomosis in 18 patients, pull-through operation in 3 patients, and optical urethrotomy in 26 patients. Followup ranged from 6 to 48 months.The mean stricture length was 3.6 cm (range from 1.5 to 8.0 cm). Posterior urethral strictures is in 31 (16%), posterior distraction defects is in 160 (84%), of which the length of the distraction defects3 cm is in 102 (53.4%), and the the length of the distraction defects3 cm is in 58 (30.6%). The overall successful results (Qmax15 ml/s) after operation was 84.3%. Optical urethrotomy was 69%, the successful results with anastomotic urethroplasty were 97% with a simple anastomosis; 79% with separation of the corporeal bodies; 80% with separation of the corporeal bodies and inferior pubectomy; 83% with transpubic anastomosis; and 67% with pull-through operation.The anastomotic urethroplasty is better than the optical urethrotomy, the length of the strictures or distraction defect which is lower than 3 cm is much more successfully corrected.

Objectives We evaluated the applications and outcomes of substitution urethroplasty, using a variety of techniques, in 65 patients with complex, long-segment urethral strictures. Methods From January 1995 to December 2005, 65 patients with complex urethral strictures >8cm in length underwent substitution urethroplasty. Of the 65 patients, 43 underwent one-stage urethral reconstruction using mucosal grafts (28 colonic mucosal graft, 12 buccal mucosal graft, and 3 bladder mucosal graft), 17 patients underwent one-stage urethroplasty using pedicle flaps, and 5 patients underwent staged Johanson's urethroplasty. Results The mean follow-up time was 4.8 yr (range; 0.8–10 yr), with an overall success rate of 76.92% (50 of 65 cases). Complications developed in 15 patients (23.08%) and included recurrent stricture in 7 (10.77%), urethrocutaneous fistula in 3 (4.62%), coloabdominal fistula in 1 (1.54%), penile chordee in 2 (3.08%), and urethral pseudodiverticulum in 2 (3.08%). Recurrent strictures and urethral pseudodiverticulum were treated successfully with a subsequent procedure, including repeat urethroplasty in six cases and urethrotomy or dilation in three. Coloabdominal fistula was corrected only by dressing change; five patients await further reconstruction. Conclusions Penile skin, colonic mucosal, and buccal mucosal grafts are excellent materials for substitution urethroplasty. Colonic mucosal graft urethroplasty is a feasible procedure for complicated urethral strictures involving the entire or multiple portions of the urethra and the technique may also be considered for urethral reconstruction in patients in whom other conventional procedures failed.

To evaluate the selection of different procedures and the feasibility for the treatment of long segment urethral stricture.Seventy-six patients with complex urethral stricture greater than 8 cm long underwent different procedures of urethroplasty. Of them various mucosa grafts urethral reconstruction were adopted in 42 cases (colonic mucosal graft, n = 26; buccal mucosal graft, n = 10; bladder mucosal graft, n = 6); One-stage pedicle flaps urethroplasty in 20; two-stage urethroplasty of Johanson procedure in 12; and penile urethra-prostatic urethra anastomosis, three-stage urethroplasty in 2.In early followed up (within 6 months postoperatively), 67 patients (88%) voided well and complications developed in 10. Among the 70 patients who lasted more than 1 year after operation, 51 cases were followed up. Forty-four patients voided well, and complications developed in 8. Of the 8 cases urethral restructure developed in 2 (18%) for pedicle flaps urethroplasty, 2 for colonic mucosal urethroplasty (9%), 1 for buccal mucosal graft (1/7), 1 for bladder mucosal graft (1/3); penile chordee in 2 (2/5), and one of them was accompanied by hair bearing neourethra for two-stage urethroplasty of Johanson procedure.Colonic mucosal and buccal mucosal grafts urethroplasty are feasible procedures for the treatment of long segment urethral stricture, and Colonic mucosal graft urethroplasty may be considered when more conventional procedures fail or complicated urethral strictures greater than 10 cm long.

To evaluate the value of ultrasonography in diagnosing urethral condyloma acuminatum (CA) in men.Twenty-two male patients, aged 36 +/- 19, diagnosed as with urethral CA based on history and clinical symptoms underwent ultrasonography and urethroscopy. The patients were asked to micturate to distend the urethra. The posterior urethra was detected by transrectum approach. Transperineal scans were performed to image the bulbar urethra, scrotal urethra and penile urethra. The sonographically positive results were compared with the pathological results.Eighty-three vegetations were found in the anterior urethra of seventeen patients, and eighty-one vegetations were diagnosed as CA by pathology, of which 1.2% were polyp shape, 38.3% papillary shape, and 60.5% cauliflower mass. Sonourethrography was an accurate predictor of papillary shape and cauliflower mass; however, it was difficult to differentiate between polyp shape vegetation and crystal.Sonourethrography is a sensitive and accurate tool not only for primary diagnosis of but also for follow-up of urethral CA in men.

To screen relatively specifical markers in urines from renal cell carcinoma patients using surface-enhanced laser desorption and ionization time of flight mass spectrometry (SELDI-TOF-MS) ProteinChip technology.Urine samples from 40 renal cell carcinoma (RCC) patients, 40 healthy volunteers and 40 patients with other urogenital diseases were analyzed using IMAC-Cu-3 PoteinChip, which can specifically bind the metal-combining-proteins. Proteomic spectra were generated by mass spectrometry.Four differentially expressed potentially biomarkers were identified with the relative molecular weights of 4020, 4637, 5070, and 5500. The sensitivity for diagnosing RCC was 57.5%, 66.7%, 63.7%, 65%, and specificity was 86.2%, 95%, 82.5% and 75% when the critical points were 2.0, 5.0, 5.0 and 5.0 respectively.SELDI-TOF-MS ProteinChip technology is a quickly, easy and convenient, and high-throughput analyzing method capable of screening several relatively specific, potential biomarkers from the urines of RCC patients and had better clinical value.

We constructed a reliable continent tube that is surgically simple.In 12 patients with malignant bladder tumor we performed radical cystectomy with isolation of a 50 cm. ileal loop with pedicle. The proximal segment (8 to 10 cm.) was tapered over a 16Fr catheter as an efferent tube, the remaining segment was detubularized to create a W-shape pouch and the tapered ileum was fixed to the back surface of the rectus muscle with 2 polyester tapers 1 cm. wide with a suspension tension of 500 g. The external orifice of the tapered ileum was anastomosed to the umbilicus. In 2 patients with neuropathic bladder a 15 cm. ileal loop with pedicle was isolated, the proximal segment (8 cm.) was tapered as an efferent tube with 500 g. suspension tension, and the remaining segment was detubularized and anastomosed to the bladder.The patients were followed for 6 to 17 months (mean 11.4) and were completely continent day and night. The stoma was easily catheterized with a 16Fr catheter in all cases. Urodynamic study of the efferent tubes revealed maximum pressure of 84 to 159 cm. water (mean 114). Retrograde radiography of the efferent tubes demonstrated perfect canalization without stenosis.This study suggests that the continent mechanism of the tapered ileum can be greatly enhanced by a suspension technique. This maneuver also provides easy catheterization and surgical simplicity.
