电切镜联合输尿管镜在腺性膀胱炎中寻找困难输尿管开口的应用

Resectoscope combined with ureteroscope in seeking for the difficult ureteral orifice in glandular cystitis

目的探讨电切镜联合输尿管镜在腺性膀胱炎中寻找困难输尿管开口的方法,提高内镜下置入双J管的成功率。方法回顾性分析2015年3月-2016年5月,8例腺性膀胱炎合并有困难输尿管开口的患者的临床资料。均为男性患者,年龄38~64岁,平均44.3岁。电切膀胱内病变,切除深度为黏膜下层和肌层,将输尿管开口区域的坏死组织切除干净,切除深度能够显露肌层的纹理改变。进一步切除肌肉组织,透过薄层肌肉组织能够看见尿液。在导丝引导下置入输尿管镜,镜下观察证实为输尿管管腔。在导丝引导下留置双J管一根。结果 8例患者(16侧)均应用电切镜联合输尿管镜成功置入双J管。手术时间35~205 min,平均时间83.2 min,术中失血量约20~50 ml。术后3~5天拔除尿管。术后1或2天复查腹部平片,显示双侧双J管位置良好,没有出现异位、扭曲等现象。围手术期未出现并发症。结论应用电切镜联合输尿管镜在腺性膀胱炎中寻找困难输尿管开口,能够提高寻找输尿管开口成功的概率,此方法安全、创伤小、避免开放手术。

Objective To investigate the method of the resectoscope combined with ureteroscope in seeking for the difficult ureteral orifice in glandular cystitis, which improved the success rate of double J stent insertion under endoscopy. Methods The clinical data of 8 patients with difficult ureteral orifice in glandular cystitis from March 2015 to May 2016 were retrospectively analyzed. All male patients, their age ranged from 38 to 64 years old, the average age was 44.3 years. The depth of the submucosa and muscle layer of the bladder lesion was treated by transurethral resection. The necrotic tissue of ureteral orifice was excised, which revealed the changing of muscular layer of texture. Then, resected the muscle tissue, urine was seen through the thin layer of muscle tissue. Under the guidance of the guide wire was inserted, the ureteroscope observation was confirmed ureteral lumen and the double J stent was placed. Results All patients were successfully placed double J stent. The mean operation time was 83.2 min (range, 35.0~205.0 min). Intraoperative blood loss was range 20~50 ml. The catheter was removed in 3~5 d. The abdominal plain film was reviewed in 1 - 2 days and the position of the double J stent was good, there was no ectopic, distortion and so on. There was no complications occurred during the perioperative period. Conclusions Resectoscope combine with ureteroscope in seeking for the difficult ureteral orifice in glandular cystitis is an effective way of increasing the successful rate of finding difficult ureteral orifice. This method is safe,minimally invasive and avoiding open surgery.
