目的评价输尿管镜治疗妊娠期合并顽固性肾绞痛的临床疗效。方法采用腰麻或硬膜外麻醉,应用输尿管镜对25例妊娠合并肾绞痛给予治疗。发现结石直径小于2mm的结石直接钳夹取出,大于2mm的结石用气压弹道碎石后取出并置入双J管,未见结石者仅置入双J管。结果 25例肾绞痛患者发现输尿管结石20例,感染并絮状小团块3例,输尿管未见明显异常者2例,18例输尿管中下结石手术顺利取出结后置入双J管石,2例发现输尿管上段小结石约3mm,由于冲至肾盂后置入双J管;其余5例未见结石者均置入双J管引流积液解除梗阻。所有病例术后疼痛均缓解,肾积水消失。25例患者均未出现异常宫缩及流产。结论输尿管镜对诊治妊娠合并顽固性肾绞痛是安全、有效的。 Objective To evaluate the clinical efficacy of ureteroscopy in the treatment of intractable renal colic during pregnancy. Methods Spinal anesthesia or epidural anesthesia was used to treat 25 cases of pregnancy complicated with renal colic by ureteroscopy. Found stones less than 2mm diameter caliper directly clamp removed, more than 2mm stones with pneumatic lithotripsy removed and placed double J tube, no stones were only placed double J tube. Results Twenty cases of renal colic were found in 20 cases of ureteral calculi, 3 cases of infection and flocculent small lumps, 2 cases of ureteral obstruction were not obvious, 18 cases of ureteral middle and lower calculus surgery were successfully removed and placed into double J pipe stone, 2 cases found that the upper ureteral calculi about 3mm, due to rush to the renal pelvis into the double J tube; the remaining 5 cases were not stones were placed double J tube drainage effusion to relieve obstruction. All cases of postoperative pain were relieved, hydronephrosis disappeared. None of the 25 patients had abnormal contractions and miscarriage. Conclusions Ureteroscopy is safe and effective in the diagnosis and treatment of pregnancy complicated with refractory renal colic.
