Résumé
PURPOSE: To evaluate the feasibility and safety of replacing the Double-J stent with a ureteral catheter in tubeless percutaneous nephrolithotomy (PCNL). MATERIALS AND METHODS: From August 1998 to February 2007, 33 patients underwent tubeless PCNL for renal calculi by the same surgeon. A retrograde 7F ureteral catheter was placed at the beginning of the surgery in all patients. A nephrostomy tube was not used in any patient. At the end of the procedure, the working tract was electrocauterized using a 26F resectoscope with a rollerball electrode; no hemostatic sealant was used. The ureteral catheter was the sole means of drainage left in place. The incidence and type of complications, the operative time, the length of hospitalization, the rate of transfusion, and the degree of pain were obtained by chart review. RESULTS: In this group of patients, the mean stone burden was 17.25 mm. The mean operative time was 71.5 min. The mean length of hospitalization was 1.9 day (range 1 to 7 days). The mean hemoglobin decrease was 0.8 g/dL. No blood transfusions were needed. The mean visual analog pain intensity scale was 1.87. Complications developed in five (15%) patients, of whom one needed a Double-J stent placement. The complications were pyelonephritis, urinary extravasation, sustained hematuria, and renal colic. The ureteral catheter was removed by postoperative day 1 in 91% of patients. CONCLUSIONS: Replacing the Double-J stent with a ureteral catheter in tubeless PCNL is an effective procedure and can be performed in patients with a moderate stone burden. The electrocauterization of the bleeding points at the end of percutaneous renal surgery with a rollerball resectoscope is safe.
