A 50-year-old male presented to the ED with recurrent episodes of gross hematuria. 30 years ago, he was admitted to our hospital and underwent left nephrectomy and orthotopic bladder substitution with ileal segments after radical cystectomy due to renal tuberculosis in the left kidney. This patient was readmitted in October 2009 with gross hematuria and underwent transurethral cystoscopic coagulation of varices in the urinary bladder (Fig. 1A). On arrival to our ED, he was initially treated with saline bladder irrigation and blood transfusion. In view of his history of recurrent gross hematuria, a contrast enhanced computed tomography (CECT, Siemens Medical Systems, Erlangen, Germany) scan of the abdomen and pelvis was performed and showed dilated blood vessels along the right side of the bladder wall with drainage into the superior mesenteric vein (SMV). Additional varix was not presented in the CT images (Fig. 1B, C).
Arterial portographies via the superior mesenteric artery showed dilated veins draining into the SMV in the right pelvic area (Fig. 1D). Percutaneous transhepatic portography (PTP) was performed by catheterization of the right anterior branch of the intrahepatic portal vein. PTP showed vesical varices with drainage into the SMV. The 10 mm diameter balloon catheter with a length of 40 mm (COOK Inc., Bloomington, IN, USA) was then advanced over the wire into the SMV. A retrograde venogram was obtained while the outflow tract was occluded with the balloon (Fig. 1E, F). A Renegade microcatheter (Boston Scientific Corporation, Natick, MA, USA) was advanced through the balloon catheter into varices using 0.14 Transcend microwire (Boston Scientific Corporation, Natick, MA, USA). The balloon catheter was inflated in the SMV to prevent the migration of 5% ethanolmaine oleate (Grelan Pharmaceutical, Tokyo, Japan)-lipiodol mixture (1 : 1). About 10 mL of the mixture was injected via the microcatheter until the entire variceal complex was opacified. After approximately 15 minutes, complete occlusion of the varices was observed during deflation of the balloon catheter (Fig. 1G). The access tract was embolized with one detachable microcoil (Interolocking detachable coil, Boston Scientfic Corporation, Natick, MA, USA) on completion of the procedure. There were no immediate complications and the patient's symptoms improved. After 6 weeks, CECT showed well obliterated vesical varices and the patient did not complain of gross hematuria (Fig. 1H, J). Follow-up cystoscopy showed the disappearance of vesical varices (Fig. 1J).
