Abstract: Objective To evaluate the clinical value of the combination of S-shaped urethral dilator and nephroscope for the treatment of male urethral strictures. Methods Under topical anesthesia or topical anesthesia combined with intravenous anesthesia, the urethral dilation with S-shaped urethral dilator were carried out in 18 cases. All dilators were inserted over guidewires in nephroscope after the examination of urethral stricture. All catheters were located across the strictures and remained for 4-6 weeks. Regular follow-up were done on all cases to assess the clinical effect of urine flow. Results All surgeries were successful without serious complications. Mean operative time was 40 min. The voiding symptoms and urinary flow rate situation were significant improved after catheter removed in all case who received urethral dilation at least 6 week during a mean follow-up time of 34 weeks. No case has incontinence, diminished sexual function and other complications. Conclusion Nephroscope combined with S-shaped urethral dilator for the treatment of male urethral stricture is intuitive, accurate, feasible, minimally invasive, safe and has a high success rate .This method is worthy of recommendation.
