Comparison of Cephazolin and Gentamicin in the Prophylactic Treatment of Infection in Out‐patient Urinary Tract Endoscopy

Previous studies have shown that the incidence of rigors following urinary tract endoscopy in out-patients may be as high as 16% 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 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.
