Urinary Catheterization

Urinary Catheterization



Basic Information image



Overview and Goal(s)


Urinary catheters can be placed to collect a sterile urine sample or to drain or lavage the bladder.



Indications




• Whenever a sterile sample of urine is needed


• Bladder paralysis


• To reduce bladder pressure postoperatively and allow healing of bladder incisions


• To allow urine flow and collection in recumbent or debilitated patients



Equipment, Anesthesia




• Sterile stallion catheter (males), mare catheter, or large-diameter Foley catheter (females)


• Sterile lube


• Sterile gloves


• Scrub for aseptic preparation of the penis or vulva


• Sedation (often unnecessary for females)



Anticipated Time


15 minutes



Preparation: Important Checkpoints


Sedation with α2 agonist drugs (xylazine, detomidine) will decrease urine specific gravity; therefore urine should be collected as soon as possible after sedation for urinalysis.



Possible Complications and Common Errors to be Avoided




• Breaks in aseptic technique or improper sterilization of equipment may cause iatrogenic urinary tract infections.


• Closed urine collection systems are difficult to maintain in nonrecumbent patients.
