Abstract
With the wide spread of maternal ultrasound, the incidence of hydronephrosis has increased significantly, altering the practice of urology. Management of antenatal hydronephrosis after birth remains controversial. The decision on surgical intervention has become more complex as a spontaneous resolution of antenatal and even neonatal upper urinary tract dilatation is being increasingly recognized. On the other hand, relief of obstruction is important to prevent irreversible damage to the developing kidneys. Ureteropelvic junction obstruction (UPJO) is the most common pathology of antenatally detected hydronephrosis. Careful follow-up and utilization of the right imaging studies can aid the urologist in tailoring the treatment to each patient individually, thus maximizing renal preservation while avoiding unnecessary interventions.
