目的 探讨同期双侧经皮肾镜碎石术的安全性及疗效. 方法 双侧肾结石或输尿管上段结石48例.其中双侧肾结石26例、一侧肾结石并发对侧输尿管结石9例、双侧输尿管上段结石5例、双侧肾结石并发一侧输尿管结石8例.结石直径1.0～7.5 cm,平均2.9 cm.其中鹿角形结石28例.患者术前血红蛋白平均(126±13)g/L,伴肾功能不全13例,SCr 188～805/μmol/L,术前透析3例.采用B超引导经皮肾镜下气压弹道联合超声碎石,双侧同期治疗.分析手术时间、失血量、输血率、住院时间、结石清除率及并发症发生情况. 结果 48例96侧均一期成功建立皮肾通路,43例双侧行一期碎石,其中4例一侧行2通道碎石;5例第二侧行二期碎石.平均手术时间(105±18)min.术后患者血红蛋白较术前平均下降21 g/L,输血5例.术后平均住院时间6.5 d.一期结石清除率77.1%(37/48),总结石清除率87.5%(42/48),4例较大残余结石者辅以ESWL治疗.无严重并发症发生. 结论 同期经皮肾镜碎石术治疗双侧肾结石或输尿管上段结石安全可行,但对肾功能差、结石负荷过大者慎行.

Objective To discuss the safety and efficacy of simultaneous bilateral percutaneous nephrolithotomy (SBPCNL) for bilateral renal or upper ureteral calculi. Methods Forty-eight cases (26 males, 22 females, 24-57 years )who underwent SBPCNL with pneumatic and ultrasonic power for bilateral renal or upper ureteral calculi were retrospectively reviewed. Clinical data including opera-tion time, blood loss, transfusion rates, length of hospital stay, stone free rate and complications were analyzed. Results The percutaneous renal access was successfully established under ultrasonic guid-ance in all patients. The average operation time was(105±18) rain(range 80-190 min). The average drop in hemoglobin was 21 g/L (range 5-54 g/L), with 5 patients requiring blood transfusion. In 43 patients, a single stage was performed on both sides, while 5 required the second stage PCNL on one side. A single tract was adopted on both sides in 44 patients, while 4 cases of the patients required two tracts on one side. No one required two tracts on both sides or more than one stage on both sides. The stone-clearance rate was 87.5 %. The average hospital stay was 6.5 d. There was no severe complica-tion occurred. Conclusion SBPCNL might be safe and effective for bilateral renal or upper ureteral calculi for selected patients.
