Retrospective outcome analysis of one-stage penile urethroplasty using a flap or graft in a homogeneous series of patients.

Abstract

To compare the results of a one-stage penile flap or graft urethroplasty. Sixty-three patients had a penile urethroplasty using one-stage techniques; 18 (29%) had a one-stage flap urethroplasty and 45 (71%) a one-stage urethroplasty using skin (23) or oral mucosal (22) grafts. The clinical outcome was considered a failure when any instrumentation was needed after surgery. The mean follow-up was 55 months; of the 63 procedures, 48 (76%) were successful and 15 (24%) failures. Of 18 patients who had a one-stage flap urethroplasty, 12 (67%) were successful and six (33%) were failures; of the 45 who had one-stage graft urethroplasty, 36 (80%) were successful and nine (20%) were failures; of 23 penile skin grafts, 18 (78%) were successful and five (22%) were failures; and of 22 oral mucosal grafts, 18 (82%) were successful and four (18%) were failures. The use of grafts for one-stage penile urethroplasty gave a higher success rate (80%) than flaps (67%). The difference in the success rate between oral mucosal grafts (82%) and skin grafts (78%) was not clinically significant.
