The risk of urinary tract infection (UTI) in normal boys is 1%.
This risk is significantly increased in boys with congenital abnormalities of the urinary tract, which includes such abnormalities as vesico-ureteric reflux, obstructive megaureter (VUJO) and posterior urethral valves. UTI in these boys can lead to urosepsis, a potentially life-threatening complication, and in the longer term renal scarring complicating pyelonephritis can lead to chronic renal impairment or even end-stage renal disease. Circumcision has been shown in normal boys to reduce the risk of UTI by 90%, and potentially could be a simple intervention to reduce the risk of urosepsis and renal scarring. In order to make this decision a clinician really needs to have the answers to two questions: 1) What is the risk of UTI in this particular boy? 2) What is the evidence of efficacy of circumcision in this particular condition? This article reviews what evidence exists to make a calculation of the risk/benefit ratio for circumcision in boys with abnormalities of the urinary tract.
