48-hour cephradine and post-prostatectomy bacteriuria

In a randomised, controlled trial of intramuscular cephradine given in a dose of 1 g 6-hourly for 48 h, there was a significant reduction in the incidence of significant bacteriuria after transurethral resection. In contrast, the incidence of significant bacteriuria after open prostatectomy was unchanged. Post-operative complications were reduced in patients who received cephradine. The use of short-term cephradine would appear to be justified.
