Peritoneo-scrotal communication: demonstration by 99mtechnetium sulphur colloid scintigraphy.

Continuous ambulatory peritoneal dialysis is a widely used and convenient alternative to haemodialysis in patients with renal failure. Occasionally, a scrotal swelling may develop during this procedure because of fluid passing through a patent processus vaginalis. We present a case report to illustrate the diagnostic use of radionuclide scintigraphy in this group of patients.
