Occult inguinal hernia, a cause of rapid onset of penile and scrotal edema in patients on chronic peritoneal dialysis.
From 1976 to 1993 we inserted 160 chronic peritoneal dialysis catheters for renal failure patients. Three of these patients developed sudden onset of penile and scrotal edema after the catheter had been in place for several months. The first patient was diagnosed by instilling technetium sulfur colloid in the peritoneal cavity, which showed the radioisotope flowing via the right inguinal canal. He was operated on and the processus vaginalis was tied off and the scrotal and penile edema resolved. Subsequently, two more patients were seen with similar problems and had their inguinal canals explored and the processus vaginalis in one and the hernia sac in the other were found and tied off, which resulted in resolution of the problem. This is an uncommon complication, reported to occur in 3 to 4% of patients.
