Abstract:
Because there is difficulty in the suture of renal pelvis, extended pyelolithotomy for the renal or pelvic calculi gives often complication such as urine leakage or infection, which result in the fibrosis and stricture of the region. Seven cases of renal stones are treated with new method using 8F Trumpet-shaped Nelaton Catheter. The proximal portion of the Nelaton Catheter inserted into the renal pelvis through the incised opening is made to arrive the lumen of the urinary bladder and the Trumpet-shaped distal portion is made to fix with the suture of the renal pelvis and capsules. After five to seven days, the catheter is removed by cystoscopic manipulation. It seems that the method is easy and feasible to decrease the complication of the extended pyelolithotomy for renal calculi.
