The Role of UTD Classification in Predicting Prognosis of Antenatal Hydronephrosis

Abstract

Evaluation of Patients with Antenatal Hydronephrosis According to UTD Classification Aim: Antenatal hydronephrosis (HN) may indicate a temporary benign condition, as well as a manifestation of congenital anomalies of the kidney and urinary system (CAKUT). Different scoring systems have been introduced to recognize CAKUT cases and to perform the necessary intervention in a timely manner. The aim of this study is to reevaluate the follow-up results of patients admitted to our hospital with antenatal HN according to the Urinary Tract Dilation (UTD) classification, and to determine the prognostic prediction of the classification in determining the presence of CAKUT and the need for surgery. Materials and Methods: Patients admitted to Adana City Training and Research Hospital Pediatric Nephrology and Urology outpatient clinics with the diagnosis of antenatal HN between February 2020-March 2021 included in the study. Patients were grouped according to the UTD classification. Results: Of the 132 patients (93 male/39 female), 84 (64%) of the patients were evaluated as transient/physiological hydronephrosis, 48 (36%) as CAKUT.
