Results of transurethral ureterolithotripsy（TUL）and clinical characteristics of post operative acute pyelonephritis

Abstract

  From April 2011 to October 2012, transurethral ureterolithotripsy with Holmium : YAG laser was performed on 104 patients at our institute. Systemic inflammatory response syndrome due to postoperative acute pyelonephritis following transurethral ureterolithotripsy occurred in 6 cases (5.8%), and 1 of these 6 patients developed septic shock and subsequently underwent nephrectomy. The overall stone-free rate was 72.1%. This study showed that shape of stones is risk factor for systemic inflammatory response syndrome due to postoperative acute pyelonephritis. Close consideration of each case preoperatively and accurate surgical techniques are crucial for a safe operation and the prevention of the postoperative complications.
