Concurrent acute appendicitis and obstructive ureterolithiasis: a case report and review of literature

The prediction of the coexistence of acute appendicitis and renal colic can be challenging, especially when the patient’s symptoms point toward one diagnosis. In this case report, we describe a patient who presented to the emergency department with severe lower abdominal pain that was thought to be solely due to acute appendicitis. Further evaluation, however, revealed the simultaneous coexistence of a right ureteral stone, causing severe hydroureteronephrosis. The patient underwent prompt surgical management, including laparoscopic appendectomy, ureteroscopy, and double-J stent insertion, and had an uneventful postoperative recovery.
