Abstract
Introduction: Renal calculi present a substantial healthcare burden globally, necessitating effective management strategies. Percutaneous Nephrolithotomy (PCNL) stands as a cornerstone for addressing kidney stones, offering high efficacy but accompanied by potential complications. This study aimed to comprehensively investigate stone prevalence in Right vs Left Kidney. Methods: A cross-sectional study was conducted between January 1st, 2022, and March 31st, 2024, involving 205 patients. 200 PCNL cases were analyzed which included patients > 18 years of age,all genders and patients underwent PCNL. 5 Patients were excluded with incomplete records, psychiatric problems, sepsis, and distal ureteric obstruction. Data encompassed demographic profiles and comparative analysis of stone prevalence. Statistical analysis utilized chi-square tests and Fisher’s exact tests. Results: The study comprised 135 males (67.5%) and 65 females (32.5%), with a mean age of 40.99 years. 55% of patients have kidney stones on the right side. The primary outcome measure, Stone-Free Rate (SFR), was assessed through postoperative imaging (ultrasound and X-ray). The SFR for the entire cohort was high, indicating the efficacy of the PCNL procedure in achieving stone clearance. Conclusion: The study demonstrates a higher prevalence of kidney stones in the right kidney (55%) compared to the left kidney (45%) among patients undergoing PCNL. These findings highlight that Kidney stones are more common on the right side then the Left side.
