AIMS: There has been much speculation and discussion about the infective complications of percutaneous nephrolithotomy (PCNL). While fever is common after PCNL, the incidence of it progressing to urosepsis is fortunately less. Which patient undergoing PCNL is at risk of developing urosepsis and in whom aggressive treatment of fever postoperatively may prevent the progression to severe sepsis becomes a very important question. This study aims to answer these vital questions. SETTINGS AND DESIGN: This is a single institutional, retrospective study over a period of 3 years...

INTRODUCTION: Percutaneous Nephrolithotomy (PCNL) is the treatment modality used for the extraction of large renal stones, or multiple calculi or stones resistant to shock wave lithotripsy. The General Anaesthesia (GA) is the standard modality for PCNL. However, few studies conclude that Spinal Anaesthesia (SA) can be an alternative method of anaesthesia with similar incidence of complications. AIM: In our study we evaluated the feasibility of spinal anaesthesia in terms of intraoperative and postoperative results in patients undergoing PCNL...
