ABSTRACT
BACKGROUND: Treatment of urethral strictures can be challenging, but, with appropriate preoperative evaluation and surgical planning it is possible to achieve successful results. OBJECTIVES: To analyze if the stricture length affects the success with dorsal onlay buccal mucosal graft urethroplasty technique. MATERIAL AND METHODS: Between January 2004 and June 2010 a total of 40 patients with anterior urethral stricture were treated with dorsal onlay buccal mucosal graft urethroplasty. Age, etiology of the stricture, stricture length (≤7 cm, and >7 cm), and localization of the stricture were assessed as the factors affecting success rate. RESULTS: The clinical outcome was defined as a failure when any operative instrumentation including dilatation was needed or the urine flow rate was less than 14 mL per second at the sixth month, postoperatively. The mean follow-up period was 43.44 months. Of 40 patients, 28 (70%) were successful and 12 (30%) were a failure. There was no statistically significant difference between the age groups, etiology of the stricture and success rate (p=0.26 and p=0.41). The statistical difference was significant for the localization and length of the stricture by means of success (p=0.002 and p=0.025). CONCLUSIONS: Our results show that the stricture length and localization are the most important variables for desirable success. Even though surgical techniques are constantly evolving, long strictures stay as a problem for urologists. Studies with larger number of patients with long urethral strictures may support our findings, and may prove the efficiency of these surgical techniques.

Pelvic fracture associated urethral injury (PFAUI) is a rare and challenging sequel of blunt pelvic trauma. Treatment of iatrogenic false urethral passage (FUP) remains as a challenge for urologists. In this case report we reviewed the iatrogenic FUP caused by wrong procedures performed in the treatment of a patient with PFAUI and the treatment of posterior urethral stricture with transperineal bulbo-prostatic anatomic urethroplasty in the management of FUP. A 37-year-old male patient with PFAUI had undergone a laparotomy procedure for pelvic bone fracture, complete urethral rupture, and bladder perforation 8 years ago. After stricture formation, patient had undergone procedures that caused FUP. Following operations, he had a low urinary flow rate, and incontinence and urgency even with small amounts of urine. FUP was diagnosed by voiding cystourethrography and retrograde urethrography. FUP was fixed with open urethroplasty with the guidance of flexible antegrade urethtoscopy. False passage should always be taken into account in the differential diagnosis of patients with persistent symptoms that underwent PFAUI therapy. In addition, we believe that in the evaluation of patients with PFAUI suspected for having a false passage, bladder neck and urethra should be assessed by combining routine voiding cystourethrography and retrograde urethrography with preoperative flexible cystoscopy via suprapubic route.
