Official title: Outcomes of Pyeloplasty in Pediatric Patients With Differential Renal Function Less Than 10%

Run by Tanta University · NCT07836621 · Data updated 2026-11-12

This study tests whether pyeloplasty can improve or stabilize kidney function in children with UPJO who have less than 10% function in the affected kidney.

Is this trial a fit for you?

Likely a good fit

Children 1 month to 18 years with primary UPJO and DRF <10% on MAG3 renogram and a normal contralateral kidney.

Probably not a fit

Patients with secondary UPJO, solitary functioning kidney, complex comorbidities, or incomplete records may not benefit or be excluded from analysis.

What this trial studies

This observational study follows pediatric patients with ureteropelvic junction obstruction and severely reduced differential renal function (less than 10%) who undergo pyeloplasty. It aims to track postoperative kidney function, changes in hydronephrosis on imaging, and clinical outcomes such as symptom relief and complications. Historically, kidneys with DRF below 10% were often removed, but recent data suggest potential for recovery after reconstructive surgery. The study will report on functional, radiographic, and clinical outcomes over the follow-up period. Eligible participants are children aged 1 month to 18 years with UPJO and a normal opposite kidney.

Why it matters

Potential benefit: If successful, children with very low preoperative function may experience stabilized or improved kidney function and reduced symptoms after pyeloplasty.

How similar studies have gone: Prior pediatric studies have shown that pyeloplasty can lead to functional improvement and symptom relief even in kidneys with low initial function.
