About

Our study will compare the rates of postoperative urinary tract infections (UTI) between patients who undergo cystoscopy using 50% dextrose injection plus bladder washout versus normal saline after hysterectomy for benign indications. Primary outcome will be rates of urinary tract infections at 6-9 days post-operatively. This will be defined as a urine culture yielding greater than 100,000 gram-negative colony-forming units per milliliter.

Full description

This will be a prospective cohort study of the rate of UTIs after cystoscopic distention media of normal saline with maximum injection of 40 cc of 50% dextrose plus 300 cc of normal saline washout versus normal saline after hysterectomy for benign indications.

A pre-operative urine culture will be obtained via mid-stream clean catch prior to administration of routine pre-operative prophylactic antibiotics.

At 6-9 days post-operatively, a repeat urine culture will be obtained via mid-stream clean catch. Appropriate treatment will be administered if the urine culture is positive.Primary outcome will be rates of urinary tract infections at 6-9 days post-operatively. This will be defined as a urine culture yielding greater than 100,000 gram-negative colony-forming units per milliliter.
