title: [Cytology in urine obtained by spontaneous miction. Its usefulness in follow-up of tumors of the bladder].
abstract: The objective of this report is to discuss the method of urine obtention through spontaneous voiding in the study of urinary cytology and its results in the follow-up of bladder tumors. 122 urine samples from 84 patients treated of urinary bladder tumor undergoing follow-up and control were studied by means of polycarbonate filters and Pap stain. The reliability of such method was evaluated by Feinstein's tests, with a sensitivity of 61.53%, a specificity of 86.88% and a global safety of 77%. The final conclusion was a positive assessment of the results obtained, and the preference for a cytological study of spontaneously voided urine, and the use of this method as the most widely used procedure in the follow-up of urinary bladder tumors.
