Relationship between upper urinary tract infection and intraoperative shivering in percutaneous nephroscopic pneumatic lithotripsy

Abstract

Objective To investigate the relationship between upper urinary tract infection and intraoperative shivering in percutaneous nephroscopic pneumatic lithotripsy. Methods The clinical data of 762 patients with midstream urine bacterial culture results who underwent percutaneous nephroscopic pneumatic lithotripsy under the spinal block anesthesia between January 2010 and December 2013 were retrospectively analyzed, to determine whether there were correlation between the incidence of intraoperative shivering in percutaneous nephroscopic pneumatic lithotripsy and upper urinary tract infection and operation time. Results The incidence of intraoperative shivering in percutaneous nephroscopic pneumatic lithotripsy in patients with upper urinary tract infection was significantly higher than those without upper urinary tract infection. The incidence of shivering in patients with more than 2 hours operation time in the two groups was significantly increased, which was found more significantly in patients with positive results of midstream urine bacterial culture. Conclusion The upper urinary tract infection is the main cause of intraoperative shivering in percutaneous nephroscopic pneumatic lithotripsy. With prolonged operation time, the incidence of shivering significantly increases. Key words: Anesthesia; upper urinary infection; percutaneous nephrolithotomy; shivering
