Abstract
SUMMARY— Previous studies have shown that the incidence of rigors following urinary tract endoscopy in out‐patients may be as high as 1 6% and that this incidence can be significantly lowered to about 7% by the administration of intramuscular cephazolin sodium at the time of endoscopy. In order to reduce further the rigor rate, a comparison of intramuscular cephazolin with gentamicin has been carried out with 200 patients in each group. There was a rigor rate of 10% and 9% respectively with no significant difference between the 2 drugs. There was no correlation between an infected urine and the occurrence of a rigor. Cephazolin sodium remains the drug of choice in this situation because of its low toxicity.
