The transplant recipient with elevated creatinine, and normal ultrasonography--detection of ureteral stenosis by magnetic resonance tomography.

hydronephrosis was not demonstrable by ultrasonoIntroduction graphy, we elected not to perform a transplant puncture for antegrade pyelography or drainage tube Urological complications are the most common type insertion. The patient underwent an MRT of the of post-transplant surgical problems [1]. Delay in transplant and this clearly demonstrated a distal transaccurate diagnosis and an inappropriate diagnosis may plant ureteral stenosis (Figures 1–3). result in the loss of the renal transplant, and is also Lower median laparotomy was performed. Intraassociated with increased morbidity and mortality [2]. operatively, the ureter of the transplant was mobilized; Transplant ureteral stenosis occurs in 3.1–10.2% of the stenotic part was identified and resected. After patients after renal transplantation [1,3,4]. The diainsertion of a 7 Charriere double-pigtail stent, an gnosis is usually made by ultrasound and radiography with contrast media. We herein present a patient with distal ureteral stenosis which could not be demonstrated by other methods, but was detected by magnetic resonance tomography (MRT ).
