The majority were male (n = 85, 79%). The median anterior-posterior renal pelvis diameter (APRPD) was 11.6 mm (IQR 9.2-14.9) and median minimal parenchymal thickness (MPT) was 5.2 mm (IQR 4.0-6.8). Diuresis renography showed a median differential function of 50% (IQR 48-53) in the affected kidney and median T1/2 was 6 min (IQR 4-11). Twenty-nine patients (27%) experienced resolution while 23 additional patients demonstrated improvement to SFU grade 2 (21%). On univariate analyses, MPT, MPT as a ratio to the contralateral measurement (MPTR) and as a ratio to age-based normal values (nMPTR) were associated with any improvement as well as complete resolution while APRPD was associated with resolution alone. On multivariate logistic regression including APRPD and MPT, each millimeter increase in MPT was independently associated with 33% increase in odds of resolution (aOR 1.33, 95%CI 1.05-1.71, p = 0.02) and 26% increase in odds of improvement to at least SFU grade 2 (aOR 1.26, 95%CI 1.02-1.59, p = 0.04).

Patients were classified according to imaging criteria into group 1 (non-functional moieties or preserved function with prompt drainage) or group 2 (impaired function or drainage). The primary outcome was surveillance failure defined as urinary tract infection (UTI), new high-grade vesicoureteral reflux (VUR), new high-grade hydronephrosis or intervention for persistent high-grade VUR or hydronephrosis. Descriptive statistics and time-to-event analysis were performed.</p><p><strong>Results: </strong>Among 73 patients with a median follow-up interval of 2.7 years (IQR 1.4-4.8), 85% were diagnosed prenatally, and 62% were female. Collecting system duplication (74%) and high-grade hydronephrosis (71%) were common. Diuresis renography was performed in 61 patients (84%). Group 1 included 42 patients (57%) and group 2 included 31 (43%). Patients in group 1 were more likely to be male (50% v. 23%, p = 0.02) and have a non-duplex collecting system (28% v. 10%, p < 0.01). Thirty-five patients in group 1 (83%) and 13 in Group 2 (42%) underwent surveillance (48 total). Among Group 1 patients who underwent surveillance, 34% developed surveillance failure (12/35), 20% experienced UTI (7/35), and 14% underwent intervention (5/35); these outcome rates were not significantly different from Group 2. Three group 1 patients underwent intervention primarily for management of VUR while concern for obstructed infection drove intervention in two others. Group 1 patients with high-grade VUR on initial evaluation had significantly higher rates of surveillance failure (71% v. 25%, p = 0.03) and intervention (43% v. 7%, p = 0.04) compared to those with low-grade or absent VUR. Most failure events occurred within 2 years of initiating surveillance and group 1 was associated with lower risk of surveillance failure (HR 0.35, 95%CI 0.14-0.85, p = 0.02) and UTI (HR 0.30, 95%CI 0.10-0.89, p = 0.03).</p><p><strong>Discussion: </strong>Patients in group 1 had outcome rates on surveillance comparable to prior published studies. Few overall underwent intervention which was often for the management of VUR. High-grade VUR was associated with surveillance failure, even amongst patients meeting the proposed surveillance imaging parameters.</p><p><strong>Conclusions: </strong>Imaging parameters supplemented by diuresis renography can aid clinical decision-making when selecting patients with ureteroceles for surveillance.
