Abstract:
Objective To explore the effect of flexible ureteroscope in treatment of retained kidney calculi after percutaneous nephrolithotomy.Methods Thirty-six patients with retained kidney calculi after percutaneous nephrolithotomy who were treated with flexible ureteroscope were selected,and clinical data of the patients were retrospectively analyzed.Results In the 36 patients,26 patients were through the percutaneous nephroscope channel,and 10 patients were through the ureter channel.Except for 1 patient who stopped the operation because of poor visibility caused by active bleeding in percutaneous nephroscope channel lithotripsy 7 d after percutaneous nephrolithotomy,other patients did not appear severe complication.All the patients were rechecked plain abdominal radiograph the second,seventh and fourteenth day after this operation,and the eradication rates of calculi were 13.9％ (5/36),69.4％ (25/36) and 94.4％ (34/36).Two patients still had less than 0.4 cm retained calculi in lower renal calices and were followed up.Conclusions The retained kidney calculi after percutaneous nephrolithotomy can be effectually treated by flexible ureteroscope,and it can avoid secondary percutaneous nephrolithotomy or multichannel percutaneous nephrolithotomy,and inprove the eradication rate of complex kidney calculi by percutaneous nephrolithotomy.The method is economical,safe,simple and with little injury,and it is the effective supplement protocol of percutaneous nephrolithotomy.
