Intraperitoneal injection of technetium-99m sulfur colloid in visualization of a peritoneo-vaginalis connection.

Ten minutes after an intraperitoneal infusion of Tc-99m sulfur colloid, a gamma camera was used to obtain anterior abdominal views. This visualized a peritoneoscrotal communication in an 80-yr-old patient. He had developed extensive edema of the genitals and lower limbs after about 6 wk of continuous ambulatory peritoneal dialysis. At operation the communication was confirmed and closed. A repeat test verified the success of operation.
