[Studies on the reaction of the rabbit testis after ligation of the arteria and vena testicularis compared with ligation of the vein alone].

In surgical treatment of Varicocele compete the ligation of the V. testicularis (Ivanissevich/Bernardi) with the ligation of the A. and V. testicularis (Palomo). Because there are doubts against throttling the arterial blood supply of a previous damaged testis, the effect of ligation of A. and V. testicularis on the testis was studied and compared with the ligation of the vein alone. On 18 adult rabbits either the Palomo operation was performed on one side, leaving the contralateral side as control, or on one side only the vein was ligated and on the other side artery and vein were ligated, permitting, so a direct comparison on the same animal. All the testes were examined histometrically. In the control group the diameter of the tubuli increased from 218 mu after 3 months to 253 mu after 10 months. In the Palomo-group the diameter decreased from 153 mu after 3 months to 82 mu after 6 months, and increased again to 153 mu after 10 months. In the Bernardi-group no differences to the normal testes were found.
