Comparative Study[The value of urine sediment cytomorphology in the ambulatory differential diagnosis of hematuria].
In order to improve early diagnosis of urotheliale neoplasms (UN) in nephrology outpatient clinic, 274 patients (221 male and 53 female, mean age 54 yrs), with recurrent hematuria (> 5 E/hpf) were investigated in years 1994-1998. The following examinations of fresh urine sediment were performed: in 114pts (group 1) erythrocytes of urine sediment examined with phase-contrast microscopy (PCM); in 129pts (group II) urine sediment examined with classical oncological cytology; in the III-rd group of 31pts (29M and 2F, aged 61-72), both methods were used because of high suspicion on UN on the ground of initial result of PCM, precisely clinical anamnesis as well as predominance of men in advanced age. Results were as follows. ⋯ In the remaining 3pts results of urinary cytology were false negative. False positive result of urinary cytology occurred in one from 9pts with glomerular hematuria and clinical or morphological (in renal biopsy) evidence of glomerulonephritis. On the results of the study, we propose--as an obligatory--in every case of recurrent hematuria of urological origin in PCM, examination of fresh urinary sediment with classical oncological cytology, especially if the patient belongs to the high risk group for urotheliale neoplasms.
