Abstract

Gross hematuria is one of the most common complications in postrenal transplant patients, accounting for 12% of all renal recipients. The management plan in these cases varies depending on different entities, including infection, renal cell carcinoma, chronic graft rejection, kidney calculus, or recurrence of primary disease. On the other hand, vascular malformation like arteriovenous malformation was less likely to be mentioned due to a lack of consensus in the natural history, pathogenesis, and current management. In this article, we report a 62-year-old man presenting with spontaneous hematuria for a week and 2 days of anuria after 3 years of renal transplantation. Abdominal ultrasound and abdominopelvic computed tomography noted an obstruction of the renal pelvis due to blood clots without signs of vascular injuries. An emergency operation was performed to remove blood clots in the renal pelvis, but after that, hematuria was still recurrence. A digital renal graft subtraction angiography (DSA) revealed an arteriovenous malformation (AVM)in the kidney allograft. This lesion was then successfully selective embolized with glue. Given the high accuracy of DSA, our case highlights the potential role of this imaging modality in diagnosing and treating AVM after failure with other modalities.
