Abstract:
To knew the prevalence and nature of asymptomatic microscopic hematuria in a community. we evaluated 13,678 cases(M; 12.198 cases, F; 1,480 cases) that visited to the Department of Health Service. Kang Nam General Hospital from April to October, 1992 for annual physical examination. For the detection of hematuria urine dipstick test was done. and then urine microscopy was done in cases with positive dipstick test (262 cases). Hematuria was defined as 3 or more RBCs/HPF on microscopic examination of the urinary sediment(189 cases). Repeated urinalysis was done in cases with 3-4 RBCs/HPF (30 cases). And in cases with 5 or more RBCs/HPF on urine microscopy, excretory urography(105 cases) was primarily checked and in addition, renal ultrasonography. cystoscopy. RGP. urine culture. urine cytology. serum IgA, C3. C4 were performed for investigation ofThe results were as follows: I. Prevalence of asymptomatic microscopic hematuria was 1.38% and significantly increased with age (p<0.01). 2. Urologic abnormalities associated with hematuria were identified in 23 cases (21.9 %)-6 cases of renal stone. 4 cases of BPH. 4 cases of UPJ stricture, 3 cases or cystitis, 2 cases of ureteral stone. 1 case or ureteral stricture. nephroptosis. renal cyst. renal tuberculosis. S. In 82 cases, urologic abnormalities could not be found and then serum IgA. C3 C4 checked in 36 cases among these. IgA was increased in 21 cases (58.3%). From the above result. the causes of asymptomatic microscopic hematuria in adults could not be found in 78.1% and serious urologic diseases tumor and so on) were almost not found. We conclude that in order to obtain the detection of accurate prevalence and various urologic diseases. repeatedurine dipstick test and long-term followup in larger populations would be needed, and that screening test for the evaluation of hematuria would consist of performing excretory urography only in relative young adults and excretory urography with selective urine cytology after age 50 years.
