目的:探讨气压弹道碎石术治疗妊娠合并输尿管结石并发肾绞痛的疗效和安全性。方法:2006年7月-2008年12月,腰麻或硬麻下行经尿道输尿管镜下气压弹道碎石术治疗26例经保守治疗无效的妊娠合并输尿管结石患者。患者年龄20~38岁,平均28岁,孕周10~37周,平均27周。结石最大径4~13mm。结果:23例患者经尿道输尿管镜下气压弹道碎石术成功,留置双J管2~4周后拔除,2例术后24小时出现宫缩或阴道少量流血,经对症处理好转,全部患者均顺利足月分娩,未出现严重产科并发症,产后均无需结石再处理。另3例因输尿管上段结石或无法进镜仅单置双J管。结论:对于保守治疗不能缓解的输尿管结石并发肾绞痛孕妇,经尿道输尿管镜下气压弹道碎石术是一种安全有效的治疗方法。
Objective: To investigate the efficacy and safety of pneumatic lithotripsy in the treatment of pregnancy-associated ureteral calculi complicated with renal colic. Methods: From July 2006 to December 2008, 26 patients undergoing conservative treatment of pregnancy complicated with ureteral calculi underwent transurethral ureteroscopic pneumatic lithotripsy under spinal or hard anesthesia. Patients aged 20 to 38 years, mean 28 years, gestational weeks 10 to 37 weeks, an average of 27 weeks. The largest diameter of stones 4 ~ 13mm. Results: Transurethral transurethral ureteroscopic pneumatic lithotripsy was successful in 2 cases. The double J tube was removed 2 to 4 weeks later. Two cases showed small contractions or vaginal bleeding 24 hours after operation. All the patients were treated with symptomatic treatment Successful full-term childbirth, no serious obstetric complications, post-natal stones without reprocessing. Another 3 cases of upper ureteral calculi due to stones or can not only single double J tube. Conclusions: Transurethral transurethral ureteroscopic pneumatic lithotripsy is a safe and effective treatment for patients with ureteral stones and renal colic who can not be relieved by conservative treatment.
