[Diagnostic value of ultrasound-guided anastomotic biopsies in patients with high PSA (> or = 0,4 ng/ml) after radical prostatectomy].

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.
