mag(2010)
Abstract
OBJECTIVES: To present minimally invasive management of annular ureteric valve that causes upper urinary tract obstructionMETHODS: 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. Ultrasonography shows a right hydroureteronephrosis with conserved parenchyma. Uro MRI (axial plane) showed dilatation until 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 clinic and the following ultrasonographies not reveal right ureteronephrosis.CONCLUSIONS: Obstructive ureteral valve resection by endourological treatment using holmium laser Dormier is a safe and effective less invasive method according to shortmedium term results.
