Circumcision: is the risk of urinary tract infection really the pivotal issue?
1Department of Pediatrics, Medical College of Ohio, Toledo 43699.
Insights
For newborn males, choosing not to circumcise offers the highest expected utility, reducing the risk of urinary tract infections (UTIs) and associated complications. This recommendation holds even when considering the procedure
Area of Science:
- Pediatric Health
- Decision Analysis
- Urology
Background:
- Recent data suggests an increased risk of urinary tract infections (UTIs) in uncircumcised male infants.
- This has led to parental confusion regarding circumcision decisions.
Purpose of the Study:
- To develop a decision model evaluating the choice between circumcision and non-circumcision for newborn males.
- To determine the optimal recommendation based on UTI risk and procedural morbidity.
Main Methods:
- A decision model was constructed incorporating probabilities of UTIs in circumcised vs. uncircumcised infants and renal scarring risk.
- Outcomes were ranked and assigned utility values (0-1 scale).
- Sensitivity analysis was performed to assess the impact of varying probabilities and aversion to procedural morbidity.
Main Results:
- Non-circumcision yielded the highest expected utility across assigned outcome values.
- Sensitivity analysis indicated non-circumcision remained preferred unless the uncircumcised UTI probability reached 0.29.
- The decision model's outcome was most sensitive to aversion to circumcision-related morbidity (pain, bleeding, inflammation).
Conclusions:
- Based on current data and a decision-analytic model, non-circumcision is the preferred choice for newborn males.
- The model highlights the significant impact of procedural risks and benefits on the circumcision decision.
- Further research may refine UTI probabilities and parental utility assessments.
Abstract:
Recent information regarding the increased risk of urinary tract infections in the first year of life for uncircumcised boys has created confusion regarding the appropriate guidance to be given to parents confronting the circumcision issue. A decision model was built that addressed the question of whether or not to circumcise a newborn male considering the probability of a non-circumcised boy having a UTI in the first year of life (0.041), the probability of a circumcised boy having a UTI in the first year of life (0.002), and the likelihood of renal scarring from a UTI (0.075). After considering the morbidity associated with the procedure, all possible outcomes were ranked from worst to best (circumcised-renal pathology to uncircumcised-no infection) and given a value on a 0 to 1 scale. For the set of values assigned to the outcomes, the choice of no circumcision yielded the highest expected utility. For the set of assigned utilities, sensitivity analysis showed that unless the probability of a UTI in the first year of life for an uncircumcised male was greater than or equal to 0.29, then non-circumcision was still the preferred choice. The decision was most sensitive to the degree of aversion to the morbidity associated with the procedure (pain, bleeding, inflammation).
