Transperineal bulboprostatic anastomosis in patients with simple traumatic posterior urethral strictures: a retrospective study from a referral urethral center.
OBJECTIVE
To evaluate the results of ancillary procedures for posterior urethroplasty and compare them with the severity of urethral stricture.


METHODS
A total of 301 patients (average age: 36 years) with posterior urethral strictures due to pelvic fracture urethral distraction defects were included in the study. Delayed transperineal bulboprostatic anastomosis was performed 6-24 months (mean 10 months) after pelvic fracture urethral distraction defects. Simple perineal anastomosis: 103 (34.2%) patients (group 1); perineal anastomosis with separation of the corporeal bodies: 89 (29.6%) patients (group 2); perineal anastomosis with inferior pubectomy: 95 (31.6%) patients (group 3); perineal anastomosis with rerouting of the urethra around the corpora cavernosum: 14 (4.7%) patients (group 4). The clinical outcome was considered a failure when any postoperative instrumentation was needed. The primary outcome examined the total success rate of the procedures. The secondary outcome examined the success rate of the procedures according to the ancillary surgical steps.


RESULTS
Of the 301 delayed transperineal bulboprostatic anastomosis procedures, 263 (87.4%) were successful and 38 (12.6%) were unsuccessful. Simple perineal anastomosis without ancillary procedures reflected an 89.3% success rate, perineal anastomosis with separation of the corporeal body had an 86.5% success rate, perineal anastomosis with inferior pubectomy had an 84.2% success rate, and perineal anastomosis with urethral rerouting had an 85.7% success rate.


CONCLUSIONS
Corporal splitting, inferior pubectomy, and urethral rerouting are beneficial and useful ancillary procedures in transperineal posterior urethroplasty to achieve tension-free anastomosis.
