METHODS: Prospective multicenter study, including pediatric patients status post-pyeloplasty (2021-2022) with standardized US assessments at 2, 6 and 9 months, 1 and 2 years after double J stent removal. The primary outcome was the percentage reduction in anteroposterior diameter (APD) of the renal pelvis compared to baseline.
RESULTS: 31 patients, median age at surgery was 6.5 months (IQR 6.5-105.5). Median preoperative APD was 24 mm (21-31 mm), with median reductions of 30% at 2 months, 60% at 6 months, 64.5% and 71.4% (40.9-82.5%) at 1 and 2 years. Median cortical thickness on the operated side improved from 4.9 mm (3.3-5.5 mm) to 8 mm at 2 years (63% increase). Median renal lengths were 72 mm (55-123 mm) on the operated side and 60 mm (50-120 mm) on the unaffected side at baseline, increasing to 88 mm (62-138 mm) and 76 mm (60-120 mm) respectively at 2 years.
CONCLUSIONS: The UUT undergoes progressive and measurable remodeling on US following pyeloplasty. Most cases show a 30% APD reduction within the first 2 months and 60% by 6 months, with minimal changes thereafter. Cortical thickness also progressively improves but typically does not reach normal values.
