Background: There has never been any report regarding the prevalence of asymptomatic microscopic hematuria (AMH) in the patients in the Southern part of Thailand. Additionally, there is also no data regarding clinical management for this kind of health condition.

Objective: To document the prevalence and management of AMH in outpatient departments of the region.

Materials and Methods: A cross-sectional descriptive study was conducted to analyze the clinical data of 511 patients, attending 10 outpatient departments of the hospital between January 2012 and May 2020. AMH was defined, according to the American Urology Association (AUA), as urine red blood cells in urine specimens greater than three per high power field, with no associated urinary symptoms.

Results: Among the 511 studied samples recruited for analysis, 73.0% of the AMH identified patients were female. The most common age and gender group was 56 to 65 years at 9.0% in males and at 24.7% in females, or about one-third of all age and gender groups. The patients from four departments, which usually send routine patient urinary examinations, including, General practice, the Primary care unit, Premium checkup, and Health care personnel surveillance, constituted of more than one-half at 56.4%, of all AMH patients from all departments. The most common investigation was repeated urinary analysis at 445/484 (91.9%), followed by urinary system imaging at 375/484 (77.5%). The most common management combination was repeated urine analysis and urinary system imaging, with urologist consultation at 225/484 (46.5%).

Conclusion: AMH is a common health condition in outpatient settings, and the patients were well managed for further investigation, according to AUA guidelines.
