Incidence of anaerobic bacterial infection following transurethral instrumentation.

Total 300 patients undergoing transurethral instrumentation had their urine culture for aerobic and anaerobic organism pre-operatively and post-operatively. An increase in the incidence of anaerobic urinary tract infection from 2% pre-operatively to 14% post-operatively following transurethral instrumentation was documented. It was concluded that transurethral instrumentation increases the incidence of anaerobic urinary tract infection and patients having symptoms of urinary tract infection following such procedures with sterile urine for aerobic bacteria should be studied and treated appropriately for anaerobic urinary tract infection.
