The penis transposed to the perineum with penile-prostatic anastomotic urethroplasty for the treatment of a long segment complex urethral strictures

BACKGROUND: To present our experience of transposing the penis to the perineum, with penile-prostatic anastomotic urethroplasty, for the treatment of complex bulbo-membranous urethral strictures. METHODS: Between January 2002 and December 2018, 20 patients with long segment urethral strictures (mean 8.6 cm, range 7.5 to 11 cm) and scarred perineoscrotal skin underwent a procedure of transposition of the penis to the perineum and the penile urethra was anastomosed to the prostatic urethra. Before admission 20 patients had unsuccessful repairs (mean 4.5, range 2 to 12); five patients were associated urethrorectal fistula; 16 patients reported severe penile erectile dysfunction (PED) or no penile erectile at any time and four reported partial erections. RESULTS: The mean follow-up period was 45.9 (range 12 to 131) months. Nineteen patients could void normally with a mean Qmax of 22.48 (range 15.6 to 31.4) mL/s. One patient developed postoperative urethral stenosis. After 1 to 10 years of the procedure, nine patients underwent the second procedure. Of the nine patients, four underwent straightening the penis and one-stage anterior urethral reconstruction using a penile circular fasciocutaneous skin flap, and five underwent straightening the penis and staged Johanson urethroplasty. Seven patients could void normally, one developed urethrocutaneous fistula and one developed urethral stenosis. CONCLUSIONS: Transposition of the penis to the perineum with pendulous-prostatic anastomotic urethroplasty may be considered as a salvage option for patients with complex long segment posterior urethral strictures.
