Substitution urethroplasty of complex and long-segment urethral strictures: a rationale for procedure selection.

Objectives: We evaluated the applications and outcomes of substitution urethroplasty, using a variety of techniques, in 65 patients with complex, long-segment urethral strictures.

Methods: From January 1995 to December 2005, 65 patients with complex urethral strictures >8cm in length underwent substitution urethroplasty. Of the 65 patients, 43 underwent one-stage urethral reconstruction using mucosal grafts (28 colonic mucosal graft, 12 buccal mucosal graft, and 3 bladder mucosal graft), 17 patients underwent one-stage urethroplasty using pedicle flaps, and 5 patients underwent staged Johanson's urethroplasty.

Efferent tube suspension as a continent diversion mechanism: a preliminary report of a clinical study.

Purpose: We constructed a reliable continent tube that is surgically simple.

Materials And Methods: In 12 patients with malignant bladder tumor we performed radical cystectomy with isolation of a 50 cm. ileal loop with pedicle.
