Abstract: Objective To investigate the efficacy and safety of ureteroscopic balloon dilatation on male urethral stricture. Methods Seventy male patients with urethral stricture treated in our hospital from January 2016 to May 2020 were randomly divided into an observation group （35 cases, ureteroscopic balloon dilatation） and a control group （35 cases, traditional urethral probe dilatation）. The therapeutic effects of the two groups were compared. Results The total effective rate of the observation group was significantly higher than that of the control group （P<0.05）. The maximum urinary flow rates of the two groups were both significantly increased after treatment （P<0.05）, and the maximum urinary flow rate of the observation group was significantly higher than that of the control group （P<0.05）. The incidence of complications of the observation group was significantly lower than that of the control group （P<0.05）. Conclusion Ureteroscopic balloon dilatation is effective and safe in the treatment of male urethral stricture and deserves clinical promotion.
