[Echographic follow-up after radical prostatectomy].

The abdominal and transrectal ultrasound is of a great importance in the follow-up and in the early postoperatory control in the patients which have undergone a radical prostatectomy. The abdominal ultrasonography can be used to identify the presence of abdominal or pelvic fluid collections in the postoperative period or to evaluating the upper urinary tract. Ultrasonography has come to play a primary role in the detection of lymphonodal and/or parenchymal metastasis. Transrectal ultrasound permits to identify the local illness relapse, whereas the ultrasonography examination during micturition allows the functional study of the bladder neck. Moreover, transrectal ultrasound is useful in guiding biopsy needle into a specific lesion seen on the sonogram in the perianastomotic region whereas random ecoguided biopsy in the perianastomotic area is necessary in patients with signs of recurrent cancer even in the absence of suspicious areas.
