ABSTRACT Purpose We investigated the possibility of urethroplasty with a free graft of colonic mucosa for long, complex urethral strictures. We report our initial experience with colonic mucosa graft urethroplasty for such urethral strictures in 16 patients. Materials and Methods Between September 2000 and December 2002, 16 patients with a long, complex urethral stricture were treated with colonic mucosal graft urethroplasty. Patients had undergone an average of 2.5 previous unsuccessful repairs. Urethral reconstruction was done with a 10 to 17 cm (median 13) graft of colonic mucosa Results Patients were followed 6 to 33 months postoperatively. Meatal stenosis that developed in 1 patient 3 months postoperatively needed reoperation. The patient was voiding well with a urinary peak flow of 28.7 ml per second during 9-month followup after reoperation. Hyperplasia of the verumontanum was observed during urethroscopy and transurethral colliculectomy was performed in 1 patient more than 14 months postoperatively. Uroflowmetry showed a urinary peak flow of 46.5 ml per second postoperatively. The other patients were voiding well with a urinary peak flow of greater than 15 ml per second. Urethrogram revealed a patent urethra with an adequate lumen and no significant graft sacculation. Conclusions This initial experience in 16 patients indicates that colonic mucosa graft urethroplasty is a feasible procedure for long, complex anterior urethral strictures. The technique may be considered for urethral reconstruction when more conventional procedures have failed.
