Abstract
Introduction: Primary obstructive megaureter is a congenital malformation of the urinary tract that consists of dilatation of the ureter with a diameter > 7 mm due to an anatomical or functional obstruction of the uretero-bladder junction, and is the second cause of neonatal hydronephrosis.
Clinical case: We present a 3-year-old male patient diagnosed with primary obstructive megaureter who underwent ureteral reimplantation by Leadbetter-Politano technique and left ureteral modeling, with placement of a double J ureteral catheter. Patient evolved favorably and the catheter was removed at 4 weeks after surgery.
Conclusions: The management of the megaureter is based on determining the underlying cause, whether obstruction, vesico-ureteral reflux or both. Currently, with advances in imaging and surgical techniques, the prognosis of patients with primary obstructive megaureter has improved significantly.
Keywords: Ureteral diseases. Hydronephrosis. Vesico-ureteral reflux. Reimplantation.
