To investigate the effect of sexual intercourse on spontaneous passage of distal ureteral stones.
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.
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).
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.
探讨性交对远端输尿管结石自然排出的影响。
采用随机数字表信封法将患者随机分为3组。第1组患者被要求每周至少性交3 - 4次。第2组患者给予坦索罗辛0.4mg/d。第3组患者仅接受标准药物治疗并作为对照组。在2周和4周后控制结石排出率。采用3×2列联表的卡方检验比较各组结石排出率的差异。P <.05被认为具有统计学意义。
第1组结石平均大小为4.7±0.8mm，第2组为5±1mm，第3组为4.9±0.8mm（P = 0.4）。两周后，性交组31例患者中有26例（83.9%）结石排出，坦索罗辛组21例患者中有10例（47.6%）结石排出，而对照组23例患者中有8例（34.8%）结石排出（P = 0.001）。第1组结石平均排出时间为10±5.8天，第2组为16.6±8.5天，第3组为18±5.5天（P = 0.0001）。
我们的结果表明，对于患有≤6mm远端输尿管结石且有性伴侣的患者，可建议其每周性交3 - 4次，以增加结石自然排出的概率。
