Nephroptosis and ureteroinguinal incarcerated hernia mimicking acute appendicitis.

ABSTRACT

The involvement of kidney, perirenal fat, and ureter is a rare variant of inguinal hernia. We report a case of a 78-year-old man presenting with typical clinical signs of acute appendicitis. Ultrasonography and CT scan revealed ptosis of the right kidney with a major part of the perirenal capsule involved in a large right sided inguinal hernia with acute obstruction of the ureter and urostasis. Acute surgery was performed, involving resection of perirenal fat, liberation, resection, and neoimplantation of the ureter, and hernioplasty. The postoperative period was uneventful. This case illustrates diagnostic unpredictability of acute appendicitis as well as anatomic variety of inguinal hernias.
