目的观察通过膀胱镜、输尿管镜或经皮肾镜引导下使用输尿管球囊扩张导管加双重双J管置入治疗输尿管良性狭窄的疗效。方法用双腔直头球囊扩张管(头端球囊长4cm)“珠头”导丝、镍钛导丝、高压注射器等设备对18例输尿管良性狭窄的患者进行扩张,扩张后放置双重双J管。结果术后随访6～48个月,术后6～9个月经造影证实肾积水减轻、输尿管扩张部位无狭窄为有效,有效率为66.7%。按有无手术病史将患者分成两组,统计学检验两组疗效无显著性差异(P>0.05)。结论球囊扩张治疗输尿管良性狭窄(<2cm)效果满意。术中放置2根双J管支撑,既有管内引流又有管外引流,对抑制远期输尿管挛缩可能起到了一定作用。但此方法可能对移植肾输尿管膀胱吻合口狭窄治疗效果不满意,需结合腔镜下内切开治疗。
Objective To observe the curative effect of ureteral balloon dilatation catheter and double double J tube guided by cystoscope, ureteroscope or percutaneous nephrolithotomy in the treatment of benign ureteral stricture. Methods 18 patients with benign ureteral stricture were dilated with double lumen straight balloon dilatation tube (head balloon length 4cm), “bead head” guide wire, NiTi guide wire, high pressure syringe and other equipment. Double double J tube. Results The patients were followed up for 6 to 48 months. The postoperative 6 to 9 months were confirmed by angiography to reduce hydronephrosis, ureter expansion without stenosis was effective, the effective rate was 66.7%. The patients were divided into two groups according to the presence or absence of surgical history. There was no significant difference between the two groups in the statistical test (P> 0.05). Conclusions Balloon dilatation is satisfactory for the treatment of benign ureteral stricture (<2cm). Intraoperative placement of two double J tube support, both within the drainage tube and drainage outside the tube, the inhibition of long-term ureteral contractures may play a role. However, this method may not be satisfied with the therapeutic effect of transplanted renal ureteric anastomotic stenosis, which requires endoscopic endoscopic treatment.
