title: Recurrence and complications after transperineal bulboprostatic anastomosis for posterior urethral strictures resulting from pelvic fracture: a retrospective study from a urethral referral centre.
abstract: OBJECTIVE
  To describe the complications of transperineal end-to-end anastomotic urethroplasty in patients with posterior urethral strictures resulting from pelvic fracture.
  
  
  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 (<0.1%) patients before trauma and in 487 (85%) patients after trauma. There was no statistical difference between the incidences of preoperative and postoperative ED (85 vs 86%, P > 0.05). Nine (1%) patients were found to have false passage between the posterior urethra and bladder neck.
  
  
  CONCLUSIONS
  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.
