Popis: OBJECTIVES To retrospectively examine our percutaneous nephrolithotomy pathway to determine the efficacy of a 6F antegrade nephroureteral catheter (NUC). METHODS The records of 99 consecutive patients who underwent percutaneous nephrolithotomy from 1998 to 2000 were reviewed. All patients were admitted the day before percutaneous nephrolithotomy and underwent placement of a nephrostomy tube. The following day, after balloon dilation of the access tract and performance of the procedure through a 30F sheath, an internal-external 6F NUC was left in place. Nephrostograms were performed on postoperative day 1, and, if negative for extravasation or residual stones, the stent was removed. The postoperative parameters included the length of stay, intravenous narcotic use, complications, and time to removal of the indwelling stent. RESULTS The average procedure time was 103 minutes (range 30 to 300), with a mean stone size of 1.7 cm. The average length of stay was 2.5 days, with postoperative intravenous narcotic use lasting 1.7 days. Of the 99 NUCs placed, 82% were removed by postoperative day 2. Eleven patients had either renal (n = 8) or ureteral (n = 3) extravasation requiring prolonged stenting, and nine had residual stones requiring a second-look procedure. Multivariate analysis demonstrated that prolonged narcotic use, days with an indwelling stent, and longer procedure times correlated significantly with a longer length of stay (P
