Abstract

Aims

Acute appendicitis is a common cause of acute abdomen in general surgery and early diagnosis is crucial for prognosis. Abnormal urinalysis results have been associated with appendicitis in some studies, with reports of microscopic hematuria or pyuria in laboratory tests. The aim of this article is to evaluate the relationship between laboratory findings of hematuria, pyuria, and the location of acute appendicitis.

Methods

This retrospective study included 577 patients who underwent appendectomy for suspected acute appendicitis between January 1, 2018, and December 31, 2022, at the general surgery clinic of Samsun Training and Research Hospital.

Results

Among the 577 patients, 247 were female and 330 were male, with a median age of 34 years. A statistically significant difference was observed between appendicitis location and erythrocyte values (p = 0.009), specifically in paraileal and retrocecal locations. There was a statistically significant difference between appendicitis location and leukocyte values (p < 0.001), with significant differences found in paraileal, promontoric, and retrocecal locations. A statistically significant difference was observed between appendicitis location and leukocyte esterase values (p = 0.002), specifically in paraileal and retrocecal locations.

Discussion/conclusion

Abnormal urinalysis findings are not uncommon in patients with acute appendicitis. Our study demonstrated a significant correlation between tit erythrocyte, tit leukocyte, and tit leukocyte esterase positivity with appendicitis locations. Therefore, we believe that pathological findings in urine tests of patients undergoing surgery with a preliminary diagnosis of appendicitis can provide valuable information to surgeons regarding the location of the appendix, ultimately aiding in optimizing the timing and cost of the operation.
