Abstract: In order to explore different surgical approaches and key techniques of prostatectomy in dogs,four hybrid dogs of 3 to 5 months old,3 to 5 kg weight were selected. When they were divided into two groups, the two surgical accesses,opening pubis and pulling bladder through midline incision at the bottom of abdomen were used. After complete removal of the prostates,urethral stumps were surtured and the dog's spirit, appetite, drinking desire, defecation, urination, etc. Three weeks later,all the dogs accepted euthanasia and their bladders and urethra suture sites were observed. The results showed that everything was normal about canine spirit, appetite, desire to drink, defecation, urination, etc. There were a small amount of bleeding spots on the bladder mucosals and the urethra suture sites had healed well. The experiment also showed that 6-0 monofilament nylon and nodular suture were good suture material and method for urethral stumps, and that urethra suture sites were coverd with pelvic adipose tissue, and was effective in preventing urine leaking and adhesion with the surrounding tissues,which was favorable for urethral stump healing.
