Abstract:
Objective To summarize the common types and clinical characteristics of ureter disease;which can increase manipulation difficulties and adverse events during rigid ureteroscopic procedures. 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.
