Standard tract percutaneous nephrolithotomy for renal calculi patients with open surgery history of kidney and upper ureter

-Objective To evaluate the efficacy and morbidity of standard tract percu taneousnephrolithotomy (PCNL) for patients with open surgery history of kidney and upper ureter. Meth odsEleven patients with open surgery history of kidney and upper ureter underwent standard tract (24 F)PCNL. Five patients had open nephrolithotomy,3 had pyeloplasty,2 had open ureterolithotomy and 1had partial nephrectomy. Five calculi were in left kidney and 6 in right side. Two cases had single cal culus,5 had multiple,and 4 had staghorn calculi. The stone burden was 1.7 47.1 cm3. ResultsAll patients were successfully operated in one session procedure. Nine PCNLs were accomplished bysingle and 2 by double accesses. The mean operating time was 86.2±34.2 min,the mean first access ing time was 14.14±11.0 min. The stone free rate after one session operation was 91% (10/11). Nocomplication occurred. Conclusion Standard tract PCNL for patients with open surgery history ofkidney and upper ureter could be effective and safe. Key words: Kidney calculi; Nephrostomy,percutaneous
