Abstract
This paper was performed to investigate the propensity of the diameter of maximum distended urethra from urethra to os penis in mature male dogs of 25 male dogs of different breeds. The measured sites of urethras were divided into 7 regions, i.e. prostate, membrane, isthmus, perineum, scrotum, prescrotum and os penis. By using the inflated balloon catheter filled with contrast medium, the maximum diameter of the distended urethras of each region was recorded and compared among regions. The mean diameter of the lumen from the prostatic urethra to the os penis urethra was gradually narrowed except for the isthmus portion, with a sense of resistance for retraction being noted at the level of ischiatic arch in 22 dogs. Proposed results from this should be utilized as a predictor of a treatment plan for the removal of urethroliths using an urohydropropulsion.
