Objectives:
To investigate the possibility and efficacy of vasoligation and deferent vein ligation in treating and preventing benign prostatic hyperplasia(BPH).
Methods:
40 male pooches were divided into A, B, C and D groups randomly. Each group has 10 pooches group A and B were made into the model of BPH. Two years later, the pooches in group A and C accepted the operation of vasoligation and deferent vein ligation on both sides. Group B and D only accepted the operation of dissection and relieving its deferent duct. Then continuing to feed the 40 pooches after the operation, they were killed another two years later. After taking out their prostates and calculating their volume and weight, the sections of the prostates were checked by microscope to observe their histology and pathology changes.
Results:
There were significant differences of weight and volume as well as the changes of histology and pathology between group A and group C (P < 0.01). It was the same with group B and D (hyperplasia changes).
Conclusions:
Vasoligation and deferent vein ligation before benign prostatic hyperplasia at pooches grow-up stage can reduce the extent of BPH at old age, and treatment after benign prostatic hyperplasia can make prostatic tissue appear different degrees of atrophy.
