Prostatic abscess

From Dog

Prostatic abscesses are prostatic disease of male dogs.

This is an inflammatory lesions where there is the formation of a cavity filled with pus. In dogs, this condition is often associated with prostatic hyperplasia[1].

Prostatic abscesses can also occur secondary to urethrorectal fistula[2], urolithiasis and paraprostatic cysts.

Clinically affected dogs often present with tenesmus, fever, and hematuria.

Diagnosis requires percutaneous ultrasound-guided biopsy or visualization via laparotomy. Anaerobic bacteria such as Bacteroides spp are commonly involved[3].

Treatment usually involves various methods of laparoscopic, laparotomy or ultrasound-guided drainage[4] of the prostate and broad-spectrum antimicrobial therapy such as enrofloxacin, amoxycillin/clavulanate or cefovecin.

A common treatment method is capsulectomy of the prostate and introduction of omentum through the capsulectomy wounds and packed into the abscess cavities around the prostatic urethra[5].
