The hydronephrosis volume (HV) to renal volume (RV) ratio was calculated using MR urography (MRU). Preoperative diethylene triamine pentaacetic acid (DTPA) differential renal function (DRF) and creatinine levels were also recorded. Patients requiring surgery were followed up after 6 months, measuring pelvis/RV ratio, creatinine, and DTPA DRF. Statistical analyses were performed to find correlations.ResultsOperated patients had a higher preoperative HV/RV ratio (AUC=0.914, 95% confidence interval [CI]=0.829-1.000; <i>P</i> <0.001) and higher DTPA DRF values (AUC=0.936, 95% CI=0.860-1.000; <i>P</i> <0.001).
