To evaluate the effect of masturbation on the spontaneous expulsion of distal ureteral stones 5-10 mm in size.

This prospective randomized controlled study was performed between February 2018 and March 2020 after obtaining ethics committee approval.A total of 128 men with distal ureteral stones were randomly divided into 3 groups. All patients received standard medical therapy. Patients in group 1 (n=43) were instructed to masturbate at least 3-4 times a week, patients in group 2 (n=41) received tamsulosin 0.4 mg/day, and patients in group 3 (controls, n=44) received standard medical therapy alone. Rates of expulsion, need for analgesic, and ureterorenoscopic lithotripsy were compared between the groups.
