[Pelvic phlebography by injection of contrast medium into the profundal dorsal penis vein for evaluation of tumor spread in cancer of the urinary bladder and prostate (author's transl)].
1. Tumors with infiltration of the mucosa and submucosa (T1) as muscularis (T2) do not cause anatomical alterations of visceral and parietal pelvic veins, as numerous phlebographies have confirmed. Internal pudendal veins and vessels of the bladder and prostate are involved in all patients with infiltration of bladder tumors into the paravesical tissue or prostate. -- 2. Phlebographic signs for metastatic lymph node involvement in carcinoma of the urinary bladder were observed in 24.5% (T2 in 11.7%, T3 in 33.8%, T4 in 25% of cases). These lesions were absent in tumors which involved the mucosal and submucosal layers (T1) only. -- 3. Alterations of the venous plexus depend on the extent of malignant infiltration in carcinoma of the urinary bladder. These can be recognized in stage II. -- 4. Pelvic phlebography may be helpful in differentiation of carcinomas and adenomas of the prostate.
