Il ruolo diagnostico delle biopsie eco-guidate della anastomosi vescico-uretrale nei pazienti con un aumento del PSA (> or = 0,4 ng/ml) dopo prostatectomia radicale.

OBJECTIVES: The authors report their experience on the use of a high number of biopsies for the diagnosis of a vesicourethral anastomosis tumor recurrence in patients who underwent radical prostatectomy with a PSA elevation. METHODS: Sixty-five patients with PSA > or = 0.4 ng/ml after radical prostatectomy received 6 to 8 transrectal ultrasound (TRUS) guided biopsies of the vesicourethral anastomosis. RESULTS: The biopsy scheme with 6 random anastomotic biopsies plus additional biopsies through TRUS detectable lesions was able to diagnose a local recurrence in more than 60% of the cases. In presence of a post-operative PSA <1.0 ng/ml and in absence of ultrasound detectable or palpable lesions a local neoplastic recurrence was detected in 58% of the cases. In presence of a palpable or ultrasound visible lesions, the detection rate increases to 80% of the cases.
