Abstract:

Objective：To evaluate the feasibility of antegrade plasmakinetic incision in the treatment of urethral stricture. Meth原
ods：Antegrade plasmakinetic incision was performed in 28 cases with urethral stricture. The ureteroscope was inserted the urethra and passed through the stricture into the bladder under direct vision，and than pulled out while an incision was made using bipolar plasmakinetic at the 4，8，12-o'clock positions until a diameter of 18F catheter could pass through. Results：25 cases were followed up at a mean time of 15.4 months（range 3 to 24），18（72%）ofthem have achieved satisfied results without complications of urinary incontinence and sexual dysfunction. Re-incision was performed two times in 4 and three times in 3 cases because of the recurrence of urethral stricture. Frequent and regular urethral dilation were performed in 6 cases range 3 to 12 months. Conclusions：Antegrade
internal urethrotomy using the ureteroscope and bipolar plasmakinetic is a safe and easy method in the treatment of urethral stricture.
