Terapia del sesso per espellere calcoli ureterali

Objective

To investigate the effect of sexual intercourse on spontaneous passage of distal ureteral stones.

Material and Methods

The patients were randomly divided into 3 groups with random number table envelope method. Patients in group 1 were asked to have sexual intercourse at least 3-4 times a week. Patients in group 2 were administered tamsulosin 0.4 mg/d. Patients in group 3 received standard medical therapy alone and acted as the controls. The expulsion rate was controlled after 2 and 4 weeks. Differences in the expulsion rate between groups were compared with the chi-square test for 3 × 2 tables. P <.05 was considered as statistically significant.

Results

The mean stone size was 4.7 ± 0.8 mm in group 1, 5 ± 1 mm group 2, and 4.9 ± 0.8 mm group 3 (P = .4). Two weeks later, 26 of 31 patients (83.9%) in the sexual intercourse group, and 10 of 21 patients (47.6%) in tamsulosin group passed their stones, whereas 8 of 23 patients (34.8%) in the control group passed their stones (P = .001). The mean stone expulsion time was 10 ± 5.8 days in group 1, 16.6 ± 8.5 days in group 2, and 18 ± 5.5 days in group 3 (P = .0001).

Conclusion

Our results have indicated that patients who have distal ureteral stones ≤6 mm and a sexual partner may be advised to have sexual intercourse 3-4 times a week to increase the probability of spontaneous passage of the stones.
