requirements in infants than with ureteral stents or external drains. Using multivariate logistic regression to adjust for patient age and weight, nephroureteral catheters in infants had a significantly higher likelihood of a parent phone call when compared with external drains or ureteral stents (p [ 0.025 and p [ 0.010). When compared to nephroureteral catheters, the odds of a documented parent phone call device was 95% lower with a ureteral stent and 85% lower with an external drain. CONCLUSIONS: Nephroureteral catheters were also associated with higher documented call rates and higher pain control requirements in infants than with ureteral stents or external drains. Avoidance of drains, catheters, or stents remains an option in this population as well.
