EVALUATION OF COMPLICATIONS AND SUCCESS RATES OF PCNL,USING MODIFIED CLAVIEN GRADING SYSTEM: A SINGLE-CENTER EXPERIENCE
OBJECTIVE: The purpose of this retrospective study is to document the perioperative complications of percutaneous nephrolithotomy (PCNL) using the modied Clavien grading system at a tertiary care centre. MATERIAL & METHODS: A retrospective study of 133 patients who underwent standard PCNL in the department of Urology and Renal Transplant,during the period January 2019 to March 2020 at Sri Aurobindo Institute of Medical Sciences,Indore, India. A structured questionnaire was used to get relevant information,while peri-operative complications were recorded using the modied Clavien grading system. RESULTS: The mean age of patients was 38.2years,male: female ratio was 1.18:1. Stones were categorized as simple in 48.9% and complex in 51.1%. The lower calyx was the commonest site of stone location (45.5%) and puncture site (76.7%). The mean operative time was about 58 minutes and the mean haemoglobin drop was 1.5g/dl. The blood transfusion rate was 3% and the stone free rate after the procedure was 93.2%. The mean length of hospital stay was 3.4 days. CONCLUSION: PCNL is an effective treatment with good clearance rate and acceptable morbidity in experienced hands.
