[Value of lymphography in prostatic cancer - comparison with pelvic en-bloc lymphadenectomy].

On the basis of 62 pelvic en bloc lymphadenectomies in the carcinoma of the prostate the lymphogenic formation of metastases is histologically determined. In 41 patients the comparison between lymphographic and histological N-determination is performed. The security of the lymphography in the carcinoma of the prostate in the lymphographically establishable pelvic region is recognized with 70%. By the pelvic en bloc lymphadenectomy in 50% of the cases a change of the preoperatively established N-determination takes place. The pedal lymphography is overestimated as method in the carcinoma of the prostate. As a secure technique in the determination of the lymphogenic formation of metastases at present the pelvic en bloc lymphadenomectomy with histological elaboration of the preparations is to be regarded. To this methods belongs a decisive diagnostic evidence in the determination of the formation of metastases of the carcinoma of the prostate by pelvic lymph nodes. The value of the lymphography consists in the simultaneous establishment of aortic metastases. Apart from this an intraoperative X-ray control may partly prove the radicality of the intervention.
