Abstract

Background: Nephrolithiasis is highly prevalent across all demographic groups in the india and beyond, and its incidence rates are rising. In addition to the morbidity of the acute event, stone disease often becomes a lifelong problem that requires preventative therapy to diminish ongoing morbidity. Objective of this study to evaluate the safety and efficacy of minimally invasive percutaneous nephrolithotomy (PCNL) in the management of large and complex renal stone.Methods: This retrospective study includes 75 renal calculi patients with 100 renal units with large and complicated stone >20 mm. Stones were classified into simple (isolated renal pelvis or isolated calyceal stones) or complex (partial or complete stag horn stones, renal pelvis stones with accompanying calyceal stones). Then various parameter like decrease haemoglobin, surgical complication, creatinine level, duration of surgery etc were compared between simple and complex stones patients by calculation p value using online student t test calculator. P value less than 0.01 considered as a difference of significance.Results: The mean stone size was 35.5±20.37 mm and mean operative duration was 60±35.3 min. In all, cases 60 (80%) were stone-free after the first procedure and another 10 needed an auxiliary procedure (5 second-look PCNL, 3 extracorporeal shockwave lithotripsy-ESWL, 2 ureterorenoscopy, and) to become stone-free, resulting in a 93.33% stone-free rate. Complications occurred in 9 procedures (12%).Conclusions: From this study, it would be concluded that Minimally invasive PCNL provided significantly higher stone-free rate and efficiency quotient for management of urinary calculi. Overall complications are usually observed in patients having intraoperative hypotension and increased intra operative time.
