The present investigation was designed to determine the differences between two methods of prostatectomy in dogs. The study conducted on eight aged, male street dogs of local breed. The experimental animals were randomly divided into two equal groups. The animals were surgically treated by two surgical techniques; first, Complete Prostatectomy (CP), and second, Subtotal Intracapsular Prostatectomy (SIP). The results showed that dogs in group1 underwent urinary incontinence after prostatectomy of normal glands, and one animal died from complications. As compared to that in group 2, the urinary obstruction was not a postoperative complication as appeared from the clinical signs. In conclusion, CP led to a series of complications could lead to death, and is indicated only for those patients with proliferative prosthetic disease and for patients with prostatic neoplasms. While, SIP procedure indicated affectivity, because urethral obstruction and urinary incontinence have not been a postoperative complication, in addition, to the fewer complications occurred, when it's compared with CP.
