4 Clinical Trials for Various Conditions
The indwelling urethral foley is a major source of discomfort following radical prostatectomy. Our hypothesis is that intra-operative dorsal penile nerve block with bupivacaine may decrease immediate post-operative foley discomfort.
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.
This is a randomized controlled study to determine the efficacy and safety of a patented urethral catheter support device designed to reduce discomfort associated with urethral catheter mobility in males. Movement of a catheter within the urethra is a source of discomfort for patients. The investigators hypothesize that this discomfort can be reduced by using an external device designed to securely fasten the catheter to the penis.
The primary aim of this randomized clinical trial is to compare the utility of phenazopyridine HCl vs. placebo in reducing catheter-associated discomfort during the post-operative period in the gynecologic patient using mean VAS measurments.
