  • Title: [Subjectivity and objectivity in transperineal biopsy and transrectal prostatic aspiration cytology].

    Abstract:
    Transperineal biopsy (TPB) together with transrectal aspirative cytology (TRAC) was performed in 50 prostates, 28 carcinomas and 22 no malignant pathologies. Both techniques were compared both objectively as subjectively. With TPB in 3.5% of carcinomas and in 13.6% of benign pathologies not enough sampling material was obtained to perform the diagnoses. With TRAC these figures were respectively 3.5% and 9%. With the viable samples TPB sensibility was 100% being TRAC 96.3%. Specificity was 100% for both techniques. With TPB, 40% of the biopsies labelled as "dubious obtention of enough material to perform diagnoses", were finally insufficient; on TRAC this rate was 11%. In the three cases of insufficient sampling material with TRAC only aspirative punction had been performed. We think it is necessary to perform more than one punction in TRAC. TRAC is, for its lack of complications, efficacy, and because it is easy to perform, the preferred technique versus TPB.
