About this trial
The purpose of this study is to determine if non-steroidal anti-inflammatory (NSAID) use in the postoperative setting increases the risk of acute kidney injury (AKI) in pediatric patients with mild-to-moderate chronic kidney disease (CKD). The investigators hypothesize that there is no increased risk. This is currently in the process of developing multi institution collaboration within a Pediatric Urology population, intended to inform future work in a larger patient population.

Trial outcomes
Primary outcomes
Frequency of Acute Kidney Injury
Acute kidney injury (AKI) will be assessed for according to Kidney Disease Improving Global Outcomes (KDIGO) criteria. Specifically, an AKI will be defined as a serum creatinine increase of ≥ 1.5 times baseline or ≥0.3 mg/dl increase within 48hrs, or a urine output \<0.5ml/kg/h for 6 to 12 hours. While there are 3 stages of AKI, the investigators will consider AKI a binary outcome since all stages are managed the same clinically. Urine output is recorded as a routine part of strict intake \& output monitoring by nursing. The serum creatinine will be compared to the pre-incisional/baseline data.
Secondary outcomes
Opiates received while inpatient
Opiate use will be calculated as morphine equivalents per day, adjusted for weight.
Days with elevated pain score
Pain scores will be assessed using the Faces Pain Scale - Revised (FPS-R) or the visual analogue scale (VAS) depending on age, per nursing routine. The former is used for patients aged 4-8 years, and latter for patients aged 9 and older. These have previously been shown to be interchangeable. Both pain scales have a range from 0-10, with 10 being the worst. This metric will not be captured for patients under 4 years of age. The percentage of days with severe, or a pain score greater than 7 will be reported.
