Evaluation of the efficacy of sexual intercourse on distal ureteral stones in women: a prospective, randomized, controlled study



To evaluate the efficacy of sexual intercourse in the expulsion of distal ureteric stones in women.

Materials and methods

A total of seventy woman patients with distal ureteral or intramural stone were randomly divided into two groups. Group 1 included 35 patients who were advised to do sexual intercourse 3–4 times/week with the administration of symptomatic treatment, and group 2 (control group) included 35 patients receiving symptomatic treatment only and were instructed not to do sexual intercourse or masturbation during the study. After 4 weeks follow up; the expulsion rate, need for analgesic and ureterorenoscopic lithotripsy were compared for each group.


The mean ages of the patients in groups 1 and 2 were 36.4 ± 10.8, 37.1 ± 12.4, respectively. The mean stone size was 7.01 ± 1.6 in group 1, 6.67 ± 1.4 mm in group 2 (p: 0.3). Stone expulsion rate, in the first 2 weeks for group 1 was 80% (28/35), while 51.4% (18/35) in group 2 (p < 0.001). In the 4th week, the expulsion rate for group 1 was 85.7%, but 60% in group 2 (p < 0.001). The mean expulsion time was shorter in group 1 (12 ± 4.2 days) than group 2 (16.1 ± 6.4 days) (p < 0.01). The analgesic needs in groups 1 and 2 were found to be 1.9 ± 0.7, 2.6 ± 0.8 times/a day respectively, and were significantly lower in group 1 (p < 0.001).


At least three or four sexual intercourses per week seem to increase the spontaneous passage for distal or intramural ureteral stones in women. Furthermore, sexual intercourse reduces the need for analgesics.
