Renal functional scintigraphy is an integral part of transplant kidney follow up1. Reflux to the transplant kidney is a common complication which can occur early after graft surgery2,3. We report a 43 year old male patient with end-stage renal disease who received a transplant kidney 13 years ago. Gradually the transplant function decreased due to chronic rejection and finally the graft became nonfunctional. The patient underwent another transplant surgery and received another graft. Renal scintigraphy with 99mTc-DTPA was performed and in addition to the new graft, abnormal activity in the location of the previous graft was seen gradually (fig. 1). Direct radionuclide cystography was performed with the suspicion of vesicoureteral reflux. Vesicoureteral reflux to both new and nonfunctional grafts was prominent (fig. 2). We recommend considering
vesiocureteral reflux when interpreting renal transplant scintigraphy, since it can be mistaken with other complications such as urine leak.
