[Sterilization of the male].

Vasoresection has great significance as a method of contraception. Next to surgicial sterilization of the female it is the most reliable method of contraception if surgical technical errors are avoided and postoperative speriograms are carried out. According to a review by Leader (2711 cases), 1 patient in 400 remaining capable of procreation must nevertheless be reckoned with. The failure is due to the fact that the surgeon did not identify a vas deferens or a spermatogranuloma led to a spontaneous recanilization. For this reason ths stumps of the vas should be stitched round. The question of electrocoagulation of the intima with ligature of the adventitia also arises.

[Morphological and clinical results after combined hormone and radiation therapy for carcinoma of the prostate (author's transl)].

83 prostatic carcinomas were analysed morphologically and clinically before and after combined therapy. The classification of these tumors is based on the proliferation pattern resulting in a group with only one and a group with a variety of growth patterns. The largest groups were carcinomas with glandular structures. On the basis of multiple biopsies the histologic regression of the tumors was determined. In 71% of the cases there was good agreement of morphological results and local palpation findings. Further analyses revealed a correlation between histological growth pattern of the carcinomas and degree of regression: prostatic carcinomas with glandular pattern showed more often a good regression after combined therapy than solid and(or) cribriform tumors. In the groups with a variety of structural pattern the degree of regression was dependent on the prevailing tumor structure. According to these results the organoid-glandular carcinomas of prostate are prognostically more favourable than all the other proliferation patterns. Nevertheless in a single case a prognosis of the therapeutic effect based only on the tumor differentiation can not be made.

[Catheter embolisation of renal tumours (author's transl)].

Arterial embolisation of renal tumours with foreign particles is described. This involves occlusion of the arteries supplying the tumour through a catheter introduced by the trans-femoral route. Pre-operative and therapeutic embolisation should be distinguished. During pre-operative embolisation, the kidney should be totally occluded by the foreign particles in order to obtain a bloodless operation zone and in order to avoid the much feared production of tumour emboli. Because of the clinical consequences of renal artery emboli, this procedure should be carried out immediately before the operation. During therapeutic embolisation, which is not followed by an operation, only those vessels supplying the tumour should be occluded in order to avoid the complications of a renal embolus. Ischemia of the tumour and less rapid growth may then be excluded.

[Familial vesico-ureteral reflux and familial urinary tract infection (author's transl)].

In 6 families several members had vesico-ureteral reflux and/or recurrent urinary tract infections. From the analysis of the case reports the following tentative conclusions could be drawn: Familial reflux may be caused. 1. by primary insufficiency of the vesico-ureteral junction. 2. possibly by secondary changes consequent to a familial tendency to recurrent urinary tract infections.
