Abstract:

Objective      To investigate the effect of green light laser combined with electron flexible cystoscope on posterior urethral stricture and obliteration after surgical treatment of prostate hyperplasia. Methods      The green light laser was applied to trea 19 patients with iatrogenic posterior urethral stricture or obliteration who were examined by an electron flexible cystoscope. Of them, 10 underwent prostatectomy, and 9 underwent transurethral resection of the prostate. After operation, the in-dwelling urethral catheter time was 1 week to 1 month. Results        All surgeries were successful without serious complications. Mean operative time was 67min (range, 25-90 min). During a follow-up of 618 months, 16 cases acquired satisfactory outcomes or were cured after 2-3 urethral dilations, and the other 3 cases were successfully treated after regular urethral dilation for 4-8 months. No case had incontinence. Conclusion       It is safe and effective to apply green light laser combined with electron flexible cystoscope to posterior urethral stricture and obliteration after surgical treatment of prostate hyperplasia.
