Kidney stones are more painful in patients with appendicitis compared to appendicitis. Kidney stones are relatively small and move within the kidney without causing obstruction and do not cause painful symptoms. Larger kidney stones can cause patients to have a sore and swollen lower back. It is when a kidney stone falls into the renal pelvis and ureteral junction causing acute hydronephrosis that the manifestation of renal colic occurs, with unbearable pain and accompanied by digestive symptoms. Appendicitis is caused by inflammatory lesions of the appendix in the abdominal cavity. Irritation of the peritoneum by inflammatory material exuding from the appendix causes severe pain with digestive symptoms such as nausea and vomiting. There is abdominal muscle tension in the appendix area with significant pressure pain and rebound pain, which requires emergency surgical management.
