Abstract
Background: Percutaneous nephrolithotomy (PCNL) is the preferred treatment for renal calculi larger than 20 mm due to its higher stone-free rates and reduced need for additional procedures. The most common nephrolithometry scoring systems to predict the outcome of PCNL are Guy's Stone Score (GSS) and S.T.O.N.E. score. The present study is aimed to evaluate the Guy's & S.T.O.N.E. scoring systems for predicting success and complications after percutaneous nephrolithotomy. Methods: This prospective study was conducted in the Department of Surgery and Urology Shyam Shah Medical College, Rewa (M.P.). One hundred fifty patients with renal stones were included in the study. The patients were given S.T.O.N.E. score and Guy's Stone Score (GSS) grades based on computerised tomography (CT) scans. The PCNL were done using a standard technique in the prone position. Outcomes were assessed based on the stone-free rate (SFR) and complications during and after the procedure. Both scoring systems were compared with the outcome. After statistical analysis, p‐value < 0.05 was taken as the significance level. Results: The average age was 39.46±15.79 years, the mean GSS was 1.75±0.67, and the S.T.O.N.E. score was 6.98±2.04. The average operating time was 60.82±22.4 minutes, and the average hospital stay was 4.88±1.12 days. Out of 150 patients, 126 (84%) were free of stones after the procedure, which was significantly decreased with an increase in both scoring systems (p-value <0.00001). A total of 50 complications were observed in 41(27.33%) patients according to the modified Clavien grading. The number and severity of complications significantly increased with an increase in both scoring systems (p-value <0.00001). Conclusion: Both the GSS and S.T.O.N.E. Scoring systems are easy to use, reproducible, and comparable in predicting the outcome of PCNL in terms of SFR and postoperative complications. These scores can be used for surgical decision-making and patient counselling
