Two cases of neonate who suffered from acute renal failure associated with bilateral hydronephrosis.

Abstract

The recent routine use of maternal ultrasonography has resulted in increasing detections of congenital hydronephrosis. The conservative management of patients with asymptomatic hydronephrosis is usually recommended because it tends to improve spontaneously. We report two cases of neonate who suffered from anuric renal failure associated with bilateral hydronephrosis secondary to posterior urethral valve or ureterovesical junction obstruction. The causes of renal insufficiency in two cases were presumebly post-renal origin because of immediate recovery after urinary drainage.
Therefore, careful follow-up in case of the neonate with bilateral hydronephrosis which might cause acute renal failure rarely in combination with urolithiasis must be needed.
