Utilidad de examen de orina en apendicitis aguda

Abstract

INTRODUCTION: The aim of this study is to observe the frequency of positive elementary microscopic examination of urine (EMO) in regard to acute appendicitis appendiceal phase, and at the same time to determinate the sensitivity of the EMO to determine the infectious appendix phase. MATERIALS AND METHODS: We performed a prospective comparative study, which evaluated the sensitivity of the positivity of the EMO, the appendix phase and the urinary symptoms seen in these patients. We included 100 patients (64 women and 46 men) with an average age of 60. RESULTS: From the patients operated on and with histological test, positive signs and symptoms were showed which were obtained in pre-surgical clinical assessment in the Vicente Corral Moscoso Hospital. EMO was considered positive when leukocytes per field exceeded 8, and presence of red cells per field larger than 4. Of the 48 cases (48%) of Suppurative Appendicitis phase only 12 of them (12%) showed positivity to make the EMO, followed in frequency by the inflammatory phase in which inside these 32 cases (32%) only 7 (7% ) of them have to do the EMO positivity. A 100% of patients with acute appendicitis suffer pain at the right fist percussion and 98% of them did not have urinary frequency. CONCLUSIONS: The positive EMO has low sensitivity to determine the appendix phase and it is higher in the gangrenous stage. EMO can be positive in patients with acute appendicitis 4-1 Patients with acute appendicitis may present positive urinary symptoms including right fist percussion and middle ureteral points.
