[The treatment of complex urethral stricture greater than 8 cm long].
OBJECTIVE
To evaluate the selection of different procedures and the feasibility for the treatment of long segment urethral stricture.


METHODS
Seventy-six patients with complex urethral stricture greater than 8 cm long underwent different procedures of urethroplasty. Of them various mucosa grafts urethral reconstruction were adopted in 42 cases (colonic mucosal graft, n = 26; buccal mucosal graft, n = 10; bladder mucosal graft, n = 6); One-stage pedicle flaps urethroplasty in 20; two-stage urethroplasty of Johanson procedure in 12; and penile urethra-prostatic urethra anastomosis, three-stage urethroplasty in 2.


RESULTS
In early followed up (within 6 months postoperatively), 67 patients (88%) voided well and complications developed in 10. Among the 70 patients who lasted more than 1 year after operation, 51 cases were followed up. Forty-four patients voided well, and complications developed in 8. Of the 8 cases urethral restructure developed in 2 (18%) for pedicle flaps urethroplasty, 2 for colonic mucosal urethroplasty (9%), 1 for buccal mucosal graft (1/7), 1 for bladder mucosal graft (1/3); penile chordee in 2 (2/5), and one of them was accompanied by hair bearing neourethra for two-stage urethroplasty of Johanson procedure.


CONCLUSIONS
Colonic mucosal and buccal mucosal grafts urethroplasty are feasible procedures for the treatment of long segment urethral stricture, and Colonic mucosal graft urethroplasty may be considered when more conventional procedures fail or complicated urethral strictures greater than 10 cm long.
