Short-course NSAID safety after surgery in children with chronic kidney disease

Safety of Short-term NSAID Use in the Postoperative Setting in Pediatric Patients With Chronic Kidney Disease

PHASE4 · University of Colorado, Denver · NCT06860711

This trial will test whether short courses of NSAIDs after surgery increase the risk of acute kidney injury in children with mild-to-moderate chronic kidney disease.

What this trial studies

This is a limited Phase 4 pilot randomized trial in a pediatric urology postoperative population comparing short-course NSAIDs to placebo for pain management. Eligible participants are children older than 18 months with CKD stage 2-3a confirmed by cystatin C within six months and without major comorbidities or contraindicated medications. The study excludes patients on ACE inhibitors/ARBs, diuretics, or trimethoprim, as well as those with prior transplant, diabetes, hypertension, nephrotic syndrome, heart failure, recent IV contrast, active infections, or NSAID allergy. Results are intended to inform safety and design of larger studies about perioperative NSAID use in pediatric CKD.

Who should consider this trial

Good fit: Children older than 18 months undergoing non-oncologic pediatric urologic surgery with CKD stage 2-3a confirmed by recent cystatin C and not taking excluded medications are ideal candidates.

Not a fit: Patients with CKD stage 1 or 4-5, those on ACEi/ARBs/diuretics/trimethoprim, with prior transplant, diabetes, hypertension, nephrotic syndrome, heart failure, recent IV contrast, active infections, or NSAID allergy are excluded and would not benefit from participation.

Why it matters

Potential benefit: If safe, this could support using short-course NSAIDs for postoperative pain in children with CKD and potentially reduce reliance on opioids.

How similar studies have performed: Adult studies and observational pediatric reports suggest NSAIDs can increase AKI risk, but randomized controlled data specifically in children with CKD are limited, making this a relatively novel pilot.
