Fetal urologic abnormalities detected by prenatal ultrasonography / 대한비뇨기과학회지

ABSTRACT

We report the clinical features of 66 neonates and infants in whom the abnormalities of the urinary tract were detected in utero by prenatal ultrasonography. The postnatal diagnosis were made by ultrasonography, voiding cystourethrography, diuretic renal scan and excretory urography, if needed. Thirty four patients had 43 ureteropelvic junction obstructions. Multicystic kidneys were found in 16 patients and ureterovesical junction obstructions were found in 17 renal units of 15 patients. Twenty one patients had multiple urologic anomalies. Thirty three patients (50%) required 40 operative procedures. No case of multicystic kidney required operation. Of 4 patients of posterior urethral valve one patient had pulmonary hypoplasia and brain hemorrhage and this case seems to have had benefit with fetal intervention. All other cases showed improvement clinically and radiologically on followup.
