Ureteral Valve Masquerading as Obstructive Megaureter
Case Presentation
A 2-year-old male child presented with pain in abdomen and crying during micturition. There was no history of urinary tract infections. The general as well as systemic examination findings did not show any abnormality. Results of the blood, urine, and culture were negative. Abdominal ultrasound showed a normal right kidney and ureter, a hydronephrotic left kidney measuring 8.2 × 3.1 × 4.2 cm, hydroureter with uniform dilatation measuring 12 mm, and a normal bladder. The MCU was normal; there was no evidence of reflux; and intravenous pyelogram (IVP) showed mild hydronephrosis, massively dilated and tortuous left lower ureter, and moderate hydroureter in the mid and upper ureter (Figure 1). Diethylene-triamine-penta-acetic acid (DTPA) scan showed delayed excretion of dye on the left side with t1/2 more than 20 min. Dimercaptosuccinic acid (DMSA) scan showed reduced function on left side, the differential being 29.7%, and absence of scars....
