Scintiphotography in the early diagnosis of urine leakage following renal transplantation.

The use of radionuclides in the evaluation of postoperative renal transplantation patients has proved to be an effective technique for the early diagnosis of urinary extravasation. It has the advantage of demonstrating the existence of urine leakage prior to visualization of extravasation on conventional cystograms and excretory urograms. It has the additional advantage of requiring no urological instrumentation and can be repeated as often as clinically indicated.
