Abstract

The aim of the present study was to assess the morbidity of ampullary renal pelvis (ARP) and document its natural history in post‑natal life. A total of 1,167 newborn infants with prenatally suspected hydronephrosis were retrospectively analyzed. Of these, 65 patients were diagnosed with ARP by computed tomography urography (CTU) and/or magnetic resonance urography (MRU). All cases were followed up with ultrasonogrophy at 1, 3, 6 and 12 months after birth, and one case was followed up for 5 years. Changes in the separation of the renal pelvis collection system were recorded. Children with ARP accounted for 5.57% of the total cases (65/1,167) followed‑up. No lack of connection between the renal calyces and the renal pelvis was detected. The long‑term follow‑up revealed that the separation of the renal pelvis collection system did not tend to increase over time. In addition to imaging examinations, long‑term follow‑up observation is recommended for the accurate diagnosis of pediatric ARP, particularly for differentiation from hydronephrosis.
