To evaluate the efficacy of sexual intercourse in the expulsion of distal ureteric stones in women.
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.
评估性交在女性远端输尿管结石排出中的疗效。
将 70 例女性远端输尿管或壁内结石患者随机分为两组。第 1 组 35 例患者在接受对症治疗的同时建议每周进行 3-4 次性交，第 2 组（对照组）35 例患者仅接受对症治疗，研究期间禁止性交或自慰。4 周后随访，比较两组的排石率、镇痛需要和输尿管镜碎石术需要。
第 1 组和第 2 组患者的平均年龄分别为 36.4±10.8、37.1±12.4，平均结石大小分别为第 1 组 7.01±1.6mm，第 2 组 6.67±1.4mm（p：0.3）。第 1 组第 1、2 周的排石率分别为 80%（28/35）和 51.4%（18/35）（p<0.001）。第 4 周时，第 1 组的排石率为 85.7%，而第 2 组为 60%（p<0.001）。第 1 组的平均排石时间较短（12±4.2 天），而第 2 组（16.1±6.4 天）较长（p<0.01）。第 1 组和第 2 组的镇痛需求分别为 1.9±0.7、2.6±0.8 次/天，第 1 组明显较低（p<0.001）。
每周至少进行 3-4 次性交似乎可以增加女性远端或壁内输尿管结石的自然排出率。此外，性交可以减少镇痛药物的需求。
