Prediction of Surgical Outcomes and Quality of Life after Percutaneous Nephrolithotomy through Guy's Score and Nephrolithometric Nomogram

Abstract

U rolithiasis has a well documented common occurrence in the general population.. Percutaneous nephrolithotomy (PNL), has prevailed over other more morbid procedures, like open surgeries in the management of large stones. PCNL in complex renal stones is a challenging procedure because it requires considerable experience in gaining percutaneous tracts, performing delicate and judicious intrarenal manipulations, mastering all techniques of intracorporeal stone disintegration, and weighing the benefits of complete stone clearance against the risks of complications. Our prospective study we evaluated Guy’s score and S.T.O.N.E. nephrolithometry scoring systems in predicting the success rate of PCNL and the quality of life. The majority of our patients (60) had pelvic stone. The stone free rate in our study was 89% with a complication rate of 18%.
