Percutaneous nephrolithotomy-a versatile technique for both simple and complex renal stone
Percutaneous Nephrolithotomy is currently the preferred first line treatment for simple & complex renal calculi. The technique also being used increasingly for smaller stones that have failed ESWL. Aim of the study is to share our experience in PCNL in course of time. This study was conducted from January 2009 to December 2012, 131 patients with 142 renal units of 5-75 yrs of age, PCNL were performed in NIKDU, BSMMU & JBFH. Stone were classified into simple (isolated renal pelvis or isolated calyceal stones) or complex (partial or complete staghorn stones, renal pelvic stone with accompanying calyceal stones). The stone size was 1.5-5cm approximately. We asses our initial puncture technique, need for multi-tract, supra 12th rib access, stone free rate, operative duration, postoperative complication, number of transfusion and hospital stay. Operative durations were 60 min -180 minutes. Puncture technique improved in course of time. 14 patients need multi-puncture and tract, all are supra 12th access. Out of 142 renal units 120 (83%) were stone free after first procedure, another 22 need and auxiliary procedure, (5 2nd look PCNL, 6 URS, 11 ESWL) to become stone free result in a 95% stone free rate. Complications occurred in 17 procedures which dealt accordingly. This study revealed PCNL is an effective, versatile safe and cosmetically acceptable procedure for all age groups in simple and complex renal stone.
