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


METHODS
Evaluation of the medical literature using Pubmed and Ovid. Revision of the clinical report of children (CH) under ET of VUR between March of 1998 and July of 2007, to find those cases that presented ureteral obstruction after ET.


RESULTS
A total of 377 children (CH) with VUR in 598 ureters (U), were treated with TE, during the mentioned period of 9 years, between March 1998 and July 2007. Only 2 U (0.33%), in 2 CH (0.5%) presented Ureteral Obstruction with dilatation of the upper urinary tract that need open surgical ureteral reimplantation, with good results in both patients.


CONCLUSIONS
The risk of ureteral obstruction after ET of VUR is low, less than 0.5% of U. The treatment of this complication can be endoscópic or by open surgery both of them with good results.
