Validity of cytologic examination of voided urine in patients with urologic cancer


, : Validity of cytologic examination of voided urine in patients with urologic cancer. Ugeskrift for Laeger 151(21): 1320-1322

Predictive tests for tumour cells in voided urine, compared with cytological and bioptic specimens taken by cystoscopy are quite similar (80-87%) but compared with the degree of malignancy, the sensitivity is least for grade I (62-77%) and greatest for grades II-III (91-94%). The low sensitivity is primarily an expression of the much greater certainty of biopsy investigations. Whereas the choice of the type of sample is not so decisive in experienced hands, the sensitivity in PV-positive test is least in cases of grade I malignant changes and least for grade II cases in PV-negative test.

We have now further analyzed this in vivo phenomenon...
