Abstract

The value of combining double contrast cystography with retrograde urethrography as a single study was investigated in 20 male dogs, which had 21 studies. These animals had been presented with suspected lower urinary tract and/or prostatic disease to Glasgow University Small Animal Hospital. The most common presenting signs were haematuria (8/21) and defaecatory tenesmus (8/21). In 18/21 studies there was poor colonic preparation, but it only affected the radiological interpretation in 6 cases. Air bubbles were found to be the commonest filling defects in bladder (12/21) and urethra (12/21). The radiological abnormality most frequently encountered was prostatomegaly (9/21), though no abnormalities were detected in 8 studies. The prostatic urethra was adequately distended or just visible in the majority of the studies (18/21) regardless of the positioning of the catheter tip. It was invisible in all but one of the 5 cases where the bladder neck was intra-pelvic. Extravasation of contrast into the substance of the prostate was observed in five of the 21 studies. Disruption or a ragged appearance to the prostatic urethra was present in the one prostatic tumour, but also in two of the four cases of prostatic/para-prostatic cyst. No evidence of mineralisation of prostatic tissue was found in any of the cases. Disease associated with the prostate was the most common final clinical diagnosis (14/21). However, benign prostatic hyperplasia was diagnosed in three cases without demonstrable prostatomegaly. The conclusion reached was that the combined technique was not superior to double contrast cystography and retrograde urethrography carried out individually. In addition, the presentation and management of ten soft tissue cases are described.
