In order to verify the practical usefulness and certain features of puncture-aspiration with fine needle of the prostate gland, a study and evaluation of our personal experience on 400 cytological samples was undertaken. A cyto-histological correlation was done on 130 of them. Excellent results were obtained relating sensitivity (97.14%), specificity (98.33%), efficacy (97.69%) and predictability indices.

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.
