Primary obstructive megaureter is an uncommon condition in adults and requires prompt surgical intervention. A 20-year-old male presented with left loin pain lasting 2 years. The Computed tomography revealed left side important hydronephrosis and dilatation of the entire ureter until the bladder. Surgical exploration revealed dilatation of the ureter in front of a relatively long (7 cm) pelvic segment, with an appearance typical of primary obstructive megaeureter. The ureterovesical reinplantation (ureteroneocystostomy) relieves obstruction and improves drainage.
