Demonstration of a renoperitoneal fistula by radionuclide renal scanning: a case report.

Radionuclide renal studies are minimally invasive, easy to perform and give information about both renal structure and function. These studies may be safely used to detect urinary ex travasations from the upper urinary tract. A case of renoperitoneal fistula imaged by nuclear medicine technique is described. (JPMA36: 118, 1986). The diagnosis of urinary extravasation using nuclear medicine procedures after trauma and renal transplants is well documented but radionuclide scanning for urinary extravasation in conditions other than these has rarely been reported Surgically related extravasations are common but they are usually small and retroperi. toneal. We describe here an iatrogenic renoperitoneal fistula which presented with tense ascites.
