The Use of 99m Technetium in the Diagnosis of Patent Processus Vaginalis

Abstract
We report 2 cases of scrotal swelling after placement of peritoneal catheters. 99mTechnetium intraperitoneal scanning was used to identify a patent processus vaginalis in each case. This simple, rapid, and nontoxic method can be used routinely to screen patients for a subclinical hernia before institution of intraperitoneal therapy.
