Introduction:

 Antenatal hydronephrosis refers to abnormal enlargement of the renal pelvis and calyces system or an increase in the anteroposterior extent of renal pelvis. In this study, we aimed to investigate the characteristics, etiologic causes, complications, and conditions required for surgery of patients who were referred to our department with the preliminary diagnosis of hydronephrosis.

Material and methods:

 The medical files of 354 patients aged between 0-16 years who admitted to our outpatient clinic with preliminary diagnosis of hydronephrosis were retrospectively screened. Demographic information, examination results, follow-up data, treatment and complications were noted from files.

Results:

Two hundred seven of the patients were male and 147 were female. Their chronological age at the time of referral to our center ranged from 0 to 186 months. On admission, anteroposterior (AP) diameter was found to be greater than 5 mm bilaterally in 80 patients (22.6%), while AP diameters were <5 mm in 35 patients (9.9%). Twelve patients with hydronephrosis (52.0% of 23 patients) with vesicoureteral reflux had grade 3 and over. While 24 of 46 patients with DMSA were found to have no scar, 8 patients had right renal scar, 7 patients had left renal scar and 5 patients had bilateral scar. While 45 of the 65 patients who underwent MAG-3 or DTPA renal scintigraphy had non-obstructive hydronephrosis, 5 had right and 12 had left obstructive, and three had bilateral obstructive hydronephrosis. Regression of hydronephrosis based on AP diameter was seen in 7.8% of cases during follow up.

Conclusions:

 Perinatal hydronephrosis should be monitored in a multidisciplinary approach. Unnecessary surgery and invasive procedures should be avoided as transient hydronephrosis also plays an important role in neonates who have hydronephrosis. The data obtained from our study provide useful information for to evaluate our centers approach to this type of disease in the context of the literature.
