[Long-term effect of one-stage urethroplasty with perineoscrotal insular skin tube in the treatment of complex posterior urethral stricture].

Thirty-one cases with complex stricture of posterior urethra were treated with one stage urethroplasty adopted perineoscrotal insular skin tube. The results of follow-up for 1 to 6 years were as follows: All cases urinated normally; The cystourethrography in 21 cases showed that urethrae were unobstructed; The urinary flow studies were carried out in 16 cases and the results showed that urinary flow rate curves were normal and that the maximum flow rate, the mean flow rate and the voiding time were all beyond normal values; The urethroscopy in 8 cases revealed that the surfaces of skin tubes remained smooth and without growth of hair stem. The facts stated as above indicated that this procedure was an ideal method for the treatment of long posterior urethral stricture.
