abstract
A 1 yr old intact male miniature dachshund presented for posturing to urinate without voiding and nocturia. Physical examination revealed congenital reproductive abnormalities and a fluid-filled structure caudal to the urinary bladder. The dog was diagnosed with a prostatic cyst and underwent an exploratory laparotomy with an attempt to remove the cyst. Twelve weeks later, the dog returned with recurring clinical signs, and the cyst was found to have returned back to its original size. A second intact male miniature dachshund presented at 7 mo of age for stranguria. Physical examination revealed congenital reproductive abnormalities and a fluid-filled structure on rectal palpation, much like the first dog. The dog was diagnosed with a prostatic cyst and underwent an exploratory laparotomy. An attempt was made to close communication between the prostate and cyst. The dog re-presented 3 wk later for recurrence of clinical signs, and the prostatic cyst was found to have increased in size. Both dogs were euthanized because of recurrence of clinical signs. This report describes the presence of prostatic cysts in two young dogs with congenital abnormalities of the genital and reproductive tracts and the similarities seen in human boys diagnosed with prostatic utricles.
