Urinary [Foley] catheters [tubes] are commonly placed in patients undergoing surgery; approximately 25% of surgical patients will receive one. Among patients who receive urinary catheters, discomfort associated with the Foley catheter is common; between 47-90% of patients experience catheter related bladder discomfort [CRBD]. Presence of a foreign object in the bladder even for short periods of time may result in symptoms such as a burning sensation, pain in the lower abdomen, muscle spasms and a sense of urgency to urinate. There is some evidence that suggests that hospital-acquired urinary tract infections are directly related to catheter placement, which causes mechanical damage and local inflammation to the urethra and the bladder. Based on research conducted on a similar mechanism where an airway tube is inserted into a patients throat for delivery of general anesthesia - we hypothesize that CRBD is related to injury and inflammation caused by the catheter placement and that this occurs in a sterile environment.
