摘要

Percutaneous nephrolithotomy (PCNL) is an intricate safe and efficacious minimally invasive endourological procedure for the vast majority of renal stones. However, same remains to be associated with certain minor and rarely some major complications. The present study aimed to retrospectively and prospectively evaluate the clinico-demographic profile and morbidity of PCNL by assessing complications according to modified Clavien classification (MCC) and analyze its possible risk factors. After obtaining prior written informed consent and institutional ethics clearance, 100 select patients undergoing PCNL were subjected to a detailed analysis of their demographic and morbidity outcome of patients using the MCC both prospectively (non-COVID period) as well as retrospectively (during COVID period) from the hospital medical case record sheets. The present study was compared with a systematic review of published medical literature using keywords PCNL, renal stones, and nephrolithiasis. Out of100 selected patients (71 retrospective and 29 prospective), the mean age was 37.6 ± 12.5 years with hypertension (10%) and type 2 diabetes mellitus (7%) being the common comorbidities. The minor complications observed were hematuria (21%) and pain (19%); the mean operating room time, mean hospital stay, and stone-free rate (SFR) were 113.25 + 26.23 min, 6.47 + 4.11 days, and > 90% (SFR) in 92% patients respectively. About 9% patients needed re-admission within 30 days of first surgery. Despite certain limitations of MCC, it can be a useful comparative analytical modality for the surgeon and urologist to evaluate and analyze the post-operative morbidity and complications of PCNL and also for multicenter comparison for most major and some minor complications of PCNL.
