Evaluation of The Efficacy of Masturbation on Distal Ureteral Stones
Purpose: To evaluate the effect of masturbation on the spontaneous expulsion of distal ureteral stones 5-10 mm in size.
Material and methods: 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.
Results: The mean ages of the patients in groups 1, 2, and 3 were 37 ± 5.0, 37.6 ± 4.6, and 38.4 ± 6.8 years, respectively (p = 0.7). The mean stone size in each group was 6.93 ± 1.1 mm, 7.1 ± 0.9 mm, and 6.87 ± 1.1 mm, respectively (p = 0.4).
Spontaneous passage rates in groups 1, 2, and 3 were 81.4%, 80.5%, and 43.2%, respectively, and were significantly higher in group 1 (p = 0.001) and group 2 (p = 0.001) when compared with group 3.
Analgesic requirement in groups 1, 2, and 3 was 1.7 ± 0.6, 1.5 ± 0.6, and 1.8 ± 0.6 times per day, respectively, and was significantly lower in the tamsulosin group than in the control group (p = 0.004)
Conclusion: Masturbation and tamsulosin increased the spontaneous passage of distal ureteral stones 5-10 mm in size. Masturbating at least 3-4 times a week was as effective as tamsulosin. Masturbation and tamsulosin also reduced the need for ureterorenoscopic lithotripsy.
