[Postoperative ureteral obstruction after endoscopic antireflux therapy].

Objectives: To know the incidence of new contralateral VUR and its evolution in children with primary unilateral vesicoureteral reflux (VUR) managed with endoscopic treatment (ET).

Methods: During 7.5 years a total of 228 children with primary VUR underwent endoscopic implantation of bulking material, 90 of them (39.

[Contralateral vesicoureteral reflux after endoscopic treatment of primary unilateral reflux].

Objectives: The endoscopic treatment (ET) of vesicoureteral reflux (VUR) is considered by many urologic and pediatric surgeons as the first treatment option in the event of being required, because it is a minimally invasive procedure, of short duration, ambulatory in many cases, with good results and few complications. Ureteral obstruction is the most serious but less frequent complication. The objective is know the incidence, treatment and evolution of patients with ureteral obstruction as complication of the ET of VUR.

[Endoscopic treatment of complicated vesicoureteral reflux grades III-V in infants under the age of one year].

Objectives: Our aim is to know the results of Endoscopic Treatment (ET) in infants with recurrent pyelonephritis and high grade (G) Vesicoureteral Reflux (VUR).

Inclusion Criteria: infants 2-12 months old with G III-V VUR and at least 2 pyelonephritis, one of them during antibiotic prophylaxis (AP). N = 27 infants: 19 males (70%) and 8 females.
