To evaluate the efficacy of sexual intercourse in expulsion of distal ureteric stones.
Patients and methods
The study included 56 patients with distal ureteric or intramural stone. The stones size ranged from 5 to 10 mm and were detected by US, plain X-ray film, and non-enhanced CT. The patients were divided randomly into group A included 28 patients who were advised to do sexual intercourse 3–4 times/week with administration of symptomatic treatment, and group B included 28 patients receiving symptomatic treatment only (control group) and were instructed not to do sexual intercourse or masturbation during the study. Follow-up (4 weeks) was done by plain X-ray, US, and urine analysis every week and by asking the patients about stone passage, time of expulsion, number of colicky attacks, and analgesic injections.
Group A patients mean age was 36.5 ± 10.7 years and group B 37.3 ± 12.5 years. Stone expulsion rate, in the first 2 weeks for group A, was 82% (23/28), while in group B 53% (16/28), (P = 0.006). At the fourth week, expulsion rate for group A reached to 89%, but in group B 71.4%. The mean expulsion time was shorter in group A (11.9 ± 4.4 days) than group B (16.2 ± 6.7 days). The number of colicky attacks and analgesics for group A was less than group B.
Practicing sexual intercourse for 3–4 times/week for married male patients with distal ureteric stone (5–10 mm) increases the expulsion rate and decreases the frequency of renal colic and the needs for analgesic.
