| Popis: | We challenge the routine placement of nephrostomy tube after percutaneous nephrolithotomy (PCNL) without taking into consideration the size, burden, and multiplicity of the stones; the degree of obstruction of the pelvicaliceal system, or any anatomic variations of the kidney in shape or position.Between January 2005 to March 2006, 110 patients underwent PCNL, 77% of whom had multiple stones. The mean size of the single stones was 4.3 cm (range 2.8-6.5 cm), and the mean single-stone burden was 7.2 cm2 (range 5.6-14.3 cm2). The mean burden of multiple stones was 11.4 cm2 (range 8-23 cm2). Among the patients, 18 had had previous renal surgery, 12 had renal insufficiency, and 7 had a solitary functioning kidney. One patient each had horseshoe kidney and malrotated kidney. In 106 patients, no nephrostomy drain was placed, only an externalized 5F ureteral catheter for 16 to 20 hours. Two patients had simultaneous bilateral tubeless PCNL. The outcome was evaluated prospectively. The frequency of complications, length of hospital stay, and stone-free status were assessed.A stone-free rate of 80% was achieved using PCNL as monotherapy. The mean postoperative hospital stay was 16 to 20 hours. Three patients required placement of a nephrostomy tube because of significant bleeding and one because of purulent renal discharge. In four patients, a ureteral catheter was replaced by a stent because of significant residual stone burdens. The initial 18 patients underwent ultrasound examination on the first postoperative day, and none demonstrated any extrarenal collection, so routine ultrasound examination was omitted in succeeding patients. One patient required exploration because of a retroperitoneal hematoma.Omission of a nephrostomy tube after PCNL while retaining an externalized ureteral catheter for 16 to 20 hours is sufficient and safe irrespective of the stone characteristics. Shape, position, and function of the kidneys are also irrelevant with regard to tubeless PCNL. |
