Pedicle patch urethroplasty for cure of urethral stricture

Repair of a prostato-membranous urethral stricture with a gracilis myocutaneous flap

A one-stage repair was carried out for a prostato-membranous urethral stricture using an epilated gracilis myocutaneous flap. The follow-up has now lasted for 2 years and 6 months. The patient has been continent and able to pass urine with a good stream. This procedure is particularly suitable for reconstruction of the posterior bulbar and prostrato-membranous urethra which is difficult to repair by standard techniques.

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.

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.
