The role of renal autotransplantation in treatment of nutcracker syndrome

To report our experience with renal autotransplantation in treatment of gross hema­turia caused by nutcracker Syndrome (NCS). Between September 2005 and January 2008, four pa­tients of mean age 25.5 years (range: 23-28) with gross hematuria were diagnosed to have NCS. Investigations revealed isolated hematuria on urinalysis, a bloody efflux from left ureteral orifice by urethrocystoscopy, dilatation of left renal vein (LRV) with significant difference in peak sys­tolic velocity in Colour Doppler UltraSonography (CDUS) and dilatation and compression of LRV between aorta and superior mesenteric artery in MRA. After operation, hematuria dis­appeared in all patients. No vascular or urological complication was seen. Follow up ranged from 4 to 24 months. In conclusion, autotransplatation of left kidney is very effective for the treatment of symptomatic NCS.
