[Transrectal echography in laser treatment of incidental prostatic carcinoma]

This report is concerning on our experience in the management of the incidental prostatic cancer treated by laser irradiation and transrectal ultrasounds (TRUS). 22 patients, with stage A incidental prostatic cancer, underwent preliminary TRUS to evaluate suspected areas of residual tumor and/or the capsule thickness. 5 patients, before the laser irradiation, have been treated with 2nd look TURP because residual tumor or much residual prostatic tissue was present. Following TRUS evaluation all the patients underwent a laser irradiation with TRUS guidance. During the laser irradiation TRUS evaluation allows to recognize the anatomy of the prostatic capsule, the thickness of the capsule and to perform a safety and complete laser irradiation of the prostatic capsule with a depth laser irradiation. In the postoperative follow-up the TRUS demonstrated, in 18 patients, a complete laser induced fibrosis of the capsule. In conclusion the TRUS represents a good technique for pre and postoperative evaluation in the patients of stage A prostatic cancer treated with laser irradiation.
