1166 OUTCOMES OF INPATIENT TESTICULAR ABSCESSES COMPLICATING EPIDIDYMITIS AND ORCHITIS AMONG HOSPITALIZED PATIENTS

prostatic abscess. Patients who did not meet any of the above criteria were defined as non-severe cases. The patients were divided into two groups; severe cases and non-severe cases. By comparing the two groups, we analyzed the independent factors associated with severe cases with ABP. We then designed and validated an algorithm for predicting outcomes and guiding appropriate treatments. RESULTS: The median age of our patients was 64.7 years. Forty-three patients were classified as severe and 165 as non-severe. Univariate analysis showed that: (1) age 65 years, (2) BPH, (3) transurethral catheter, (4) urinary retention, (5) pain on urination, (6) coma, (7) low blood pressure, (8) heart rate 120 bpm, (9) body temperature 38.0 degrees C, (10) WBC 18,000/ l, and (11) BUN 19 mg/dl were significantly associated with severe cases with ABP. Multivariate analysis showed that: (1) low blood pressure, (2) WBC 18,000/ l and (3) BUN 19 mg/dl were independently associated with severe cases of ABP. Based on the information above, we constructed an algorithm that can successfully assist physicians in making decisions about treatment and disposition. By utilizing the algorithm to predict severe cases at initial visits, the sensitivity and specificity were 88.4% and 87.3%, respectively. CONCLUSIONS: The algorithm proposed had high sensitivity and specificity for predicting severe cases and has the potential to standardize the initial management of patients diagnosed with ABP. This algorithm-based approach may have the potential to identify high-risk patients who require hospitalization and intensive care.
