Urethral flap urethroplasty

The controversy of single versus multistaged urethroplasty

Experience with various 1 stage repairs for urethral strictures (patch graft, and excision and reanastomosis techniques) gained by ourselves and others is compared to reports on multistaged urethroplasties (Johanson, Leadbetter-Johanson and Turner-Warwick). Increased hospitalization, absence from employment and the morbidity of multiple anesthetics and operations are features of the multistaged approaches compared to the 1 stage operations. Furthermore, no advantage was seen when initial or final success rates were compared.

Two-stage urethroplasty for urethral stricture disease

Of 97 patients who underwent first-stage urethroplasty 23 per cent required at least 1 revision. Sixty-seven patients underwent second-stage reconstruction with a 90 per cent success rate. The various factors influencing the outcome of 2-stage urethroplasty procedures are analyzed critically.

Dermal patch urethroplasty: experimental and clinical experience

Our experience with a dermal patch graft urethroplasty is presented in 10 Pitman-Moore minipigs. Histologic review at various post-urethroplasty intervals showed epithelialization of the graft. In addition, several cases in which this technique was used are presented with early followup. The advantages of dermal patch urethroplasty as well as the application of dermal grafts in other areas of the urinary tract are discussed.
