MARCH VILLALBA, José Antonio et al. Conservative treatmet of ureteral valve with holmium laser in a child. Arch. Esp. Urol. [online]. 2010, vol.63, n.3, pp.231-234. ISSN 0004-0614.

Objectives: To present the minimally invasive management of an annular ureteric valve causing upper urinary tract obstruction. Methods: A case report description: endourological technique and medium-term results with review of the published reports. Results: A 12 year old patient with right flank pain was attended. Ultrasound showed right ureterohydronephrosis with conserved parenchyma. Uro-MRI (axial plane) showed dilation down to the middle of the right ureter with a filling defect, without extrinsic compression. Ureterorenoscopy showed a ureteral valve that was resected by holmium laser. Ureteral stent was maintained for 3 weeks. Twelve months after treatment patient has no symptoms and the following ultrasounds did not reveal right ureterohydronephrosis. Conclusions: Obstructive ureteral valve resection by endourological treatment using a Dornier holmium laser is a safe and effective minimally invasive method according to short and medium term results.
