目的探讨输尿管镜术中输尿管口丢失的应对方法。方法报告输尿管镜术中因输尿管口丢失而进镜失败的14例患者的处理过程及结果。先采用斜仰卧截石位,实时超声定位下以G18穿刺针朝向肾盂输尿管连接部穿刺患肾中上盏,从针芯中顺行向输尿管内推置亲水导丝,如可见导丝进入膀胱,则沿导丝径路进镜;如导丝无法顺行进入膀胱,则换用经尿道电切镜,薄层电切患侧输尿管口对应部位,显露输尿管壁内段断端,置入亲水导丝后换用输尿管镜进镜。所有患者术后均留置F7双J管1~2根。结果11例肾穿刺顺行置入导丝可见进入膀胱,沿导丝成功进镜入输尿管;3例此法失败者采用输尿管口部位电切法成功进镜。所有患者肾穿刺针和导丝拔除后无大出血,无输尿管穿孔、撕脱等严重并发症,术后2~3个月拔除双J管后未发生输尿管口狭窄。结论输尿管镜术中发生输尿管口丢失,依次采用肾穿刺顺行导丝置入法和输尿管口部位电切法寻找输尿管口成功率高,创伤小,无严重并发症发生。 相似文献

J L Huffman 《The Urologic clinics of North America》1989,16(2):249-254
Kaufman reported a severe ureteral injury following ureteroscopy in 1984. His commentary summarizes the important messages in this article well: The intent of this report is not to denegrate the splendid advances in nephroscopy and ureteroscopy, but rather to introduce a sobering message that the patient must be informed of the inherent risk of such procedures and that the urologist must be wary of the problems that might occur. Problems have been known ever since endoscopic instrumentation was first introduced, and every experienced urologist has had his share of problems associated with stone extraction and other endoscopic procedures. Traditional teaching in urology has been to eschew manipulation of stones in the upper two thirds of the ureter because the lumbar ureter is mobile and more easily damaged by instrumentation than the pelvic segment. Endoscopic visualization of stones in the upper ureter allowing accurate grasping of calculi would appear at first to provide an element of security heretofore unachievable, but urologists nonetheless should be mindful of the hazards of any type of stone extraction from the upper ureter. Urologists must be ready and equipped to handle emergencies associated with new instruments and techniques, and the patients must be apprised of the exigencies. "Caveat emptor" (buyer beware) could not be a more apt or timely maxim in our specialty. Ureteroscopy has greatly aided many patients, and a large number of urologists have integrated this procedure into their daily practices.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

Methods From Jan 2001 to Dec 2010,our team performed 317 rigid ureteroscopic Drocedures for ureteroscopic examination or treatment;including 60 difficult procedures(34 male and 26 female).The mean age of the patients was 37 years (range,18 to 71).The ureteral diseases were classifted into five types according to the pathological characteristics:Type Ⅰ calculous stenosis,Type Ⅱ neoplastic stenosis;Type Ⅲ non-congenital stenosis,Type Ⅳ congenital stenosis,Type Ⅴ expansion of tortuous ureters.The operative time,complications,and conversion to open surgery were evaluated,and the therapeutic methods were analyzed. Results Of the 60 difficuhly-manipulated procedures,the mean manipulated time was 75 min (range,31 to 200).Intra-operative complications occurred in 9 procedures,including 4 cases of mucosal bleeding,2 cases of submucosaI false passage and 3 cases of ureteral perforation.Eleven procedures were converted to open surgery. In five procedures only a double J tube was inserted for drainage due to the difficulty of entering the ureter.Fiftyfive patients were followed up for 17 months (range,3 to 110);48 patients were cured,5 patients improved and 2 patients were unchanged. Conclusions The five types of ureteral disease can increase operative difficulties and risks of rigid ureteroscopic procedures.We should be cautious during surgery and should stop manipulation or convert to other surgeries if necessary. 相似文献

This is one case of ectopic ureter which lacked urinary incontinence despite ureteric orifice in the vestibulum. Case: A 20-year-old woman complained of miction pain. On examination, we found a small orifice in the vestibulum. DIP revealed slight hydronephrosis in the left contracted kidney and normal pyelogram in the right kidney. On cystoscopy, the bilateral ureteral orifices were normal, but we found the head of a catheter placed in the orifice of the vestibulum was passing under the mucosa of the bladder. The abnormal lumen was recognized by introducing an opaque medium through a catheter placed into the orifice of the vestibulum. The diagnosis was an abnormal left ureteral ectopic opening into the vestibulum with left complete duplication of renal pelvis and ureter. Left heminephro-ureterectomy was performed. Some discussions about the ectopic ureteral orifice without incontinence were conducted. 相似文献
