Is Antibiotic Administration Indicated after Outpatient Cystoscopy

Abstract

The incidence of urinary tract infection was examined in 138 patients who underwent diagnostic cystoscopy in an outpatient clinical setting with preoperatively sterile urine. A prospective randomized trial was conducted to compare the incidence of infection in patients who received no antibiotic (controls, group 1) and those who received a postoperative course of oral antibiotics (group 2). The incidence of bacteriuria after cystoscopy was 2.8 percent in group 1 (control) and 1.5 percent in group 2, with an over-all incidence of 2.2 percent. Only 1 patient presented with a symptomatic infection (0.7 percent). This study was confirmed the safety of outpatient cystoscopy and has demonstrated that routine administration of postoperative antibiotics is not indicated.
