Excision and anastomotic repair for urethral stricture disease: experience with 150 cases.

PURPOSE: To analyze the results of a series of end-to-end urethroplasties performed in our service from 1968 to 1995 and of the factors contributing to failure.

MATERIAL AND

METHODS

150 men (mean age 35.9 years) with urethral stricture disease underwent excision of the stricture and end-to-end anastomosis; in 95 it was the first attempt at repair while in 55 it was a secondary attempt. Eighty-two patients (54.6%) had a trauma-related stricture; of them, 56 followed a pelvic ring fracture with posterior urethra distraction defect, 24 (16%) had inflammatory strictures, 26 (17.3%) iatrogenic, 9 (6%) congenital, and 9 (6%) of unknown etiology; 81 (54%) were located in the bulbous urethra, 9 (6%) in the penoscrotal junction and 2 (1.3%) in the penile urethra. Ninety-one (60.6%) of the strictures or obliterative defects measured between 1 and 3 cm, 42 (28%) less than 1 cm and only 16 (10.6%) more than 3 cm. A perineal approach was used in 138 of the cases, while combined abdominoperineal route was necessary in 12; of these, 5 were children. The follow-up has ranged from 6 to 168 months (mean 44.4). The results were classified as good, fair (some re-stricturing, not needing treatment) and poor (recurrence).

RESULTS

One hundred and twenty-six (84%) good outcomes, 10 (6.6%) fair, 14 (9.3%) poor. The factors influencing success or failure were: (1) primary or secondary character of the operation; (2) etiology; (3) length, and (4) location. Postoperative early complications consisted of 2 wound infections and 2 hematomas; as late complications, 1 chordee, 2 incontinence, 7 erectile dysfunction (in previously potent patients). The 14 patients considered as failures were operated again, all successfully; in 4 of them, a repeat excision and end-to-end anastomosis was performed, elevating the final success rate of the series to 93.3%.

CONCLUSION

Excision and anastomotic repair represent the optimal mode of stricture repair for single lesions located from the penoscrotal junction to the membranous part of the urethra.
