PARENTE HERNANDEZ, A. et al. Management endourologic of pyeloureteral junction stenosis. Actas Urol Esp [online]. 2006, vol.30, n.9, pp.933-938. ISSN 0210-4806.

Objetives: To report our experience with endourologic methods in the treatment of pyeloureteral stenosis in children. Materials and Methods: From July 2004, 7 patients from 9 months to 15 years old with pyeloureteral junction stenosis (PUJ) diagnosis underwent endourologic repair. An endourological dilatation was made under radioscopic control. The procedures consist of an initial cystoscopy with a retrograde placement of catheter (4 or 5 Fr) and the guide wire (0,014´´or 0,035´´). The high pressure balloon (3 to 5 Fr) was then railroad over the wire and positioned across the stenosis for dilatation. A double J stent (3 to 6 Fr) was then introduced, remaining it during 6 weeks. Results: There was no intraoperative complications. Median inhospital stay was 2 days (range, 2 to 8). The double J stent was removed without complications. All patients are asymptomatic with improvement in excretion times (MAG3 renography) and antero-posterior renal pelvis diameter (ultrasound measurement). Conclusions: Balloon dilatation is a viable option in the management of PUJ obstruction even in children under one year old, with minimal morbidity.
