Transperineal bulboprostatic anastomotic repair of pelvic fracture urethral distraction defect and role of ancillary maneuver: A retrospective study in 172 patients

Abstract

Objective: We present our experience with transperineal bulboprostatic anastomosis procedure and compare the results with age of patients, length of urethral stricture, effect of previous treatment and need for ancillary procedures.

Materials and methods: We retrospectively reviewed the outcome of 172 patients who underwent perineal urethroplasty procedure for traumatic stricture in our institute. Simple perineal anastomosis was done in 92 patients. Perineal anastomosis and corporal separation were done in 52 patients. Perineal anastomosis with inferior pubectomy was done in 25 patients. Perineal anastomosis with rerouting was done in three patients. Age, prior treatment, length of stricture, and ancillary techniques required during reconstruction were compiled. The clinical outcome was considered as failure when any postoperative instrumentation was needed.

Results: Out of 172 cases that underwent transperineal urethroplasty procedure, 157 (91.28%) were successful. Simple perineal urethroplasty procedure showed a success rate of 93.4%, perineal anastomosis with separation of corporal bodies had a success rate of 90.4%, perineal anastomosis with inferior pubectomy had a success rate of 88% and perineal anastomosis with rerouting of urethra around the corpora had a success rate of 66.7%.

Conclusion: The success rate of delayed progressive perineal urethroplasty procedure for post-traumatic stricture urethra is excellent and majority of the failures occurs in prepubescent boys and in those undergoing secondary repair.
