Abstract
Effects of 3 days of open indwelling urethral catheterization were evaluated in normal male cats. Polypropylene and polyvinyl feline urinary catheters of sufficient length to permit constant urine drainage were compared. Catheters were similar in length, diameter and design. Hematuria occurred in 6 of 6 cats with polypropylene catheters and in 4 of 6 cats with polyvinyl catheters. For cats with polypropylene catheters, hematuria began within 24 h of catheter insertion. Hematuria induced by polypropylene catheters was more severe in final urinalyses. Catheter-induced bacteriuria was found in 5 of 6 cats with polypropylene catheters and in 3 of 6 cats with polyvinyl catheters. Staphylococcus and Streptococcus were the most common bacterial isolates. Microscopic lesions in urethras and bladders were significantly less severe in cats with polyvinyl catheters. With few exceptions, urethras of cats with polyvinyl catheters were microscopically indistinquishable from urethras of noncatheterized cats. Polypropylene catheters consistently induced urethritis which was most severe in some bacteriuric cats. Severe lesions were found in bladders of all cats with polypropylene catheters. Bladder lesions were common in cats with polyvinyl catheters but were less severe. There was no apparent relation between bacteriuria and bladder lesions. In a recent study of indwelling urethral catheters in normal male cats, direct injury to the urethral wall by catheters was observed. Because catheters used were too short to reach the lumen of the bladder, direct injury to the bladder wall did not occur. Catheter-induced ascending bacteriuria did cause significant bladder lesions.
