Brief summary

The purpose of this study is to determine whether cleaning of the urethra, or external opening to the bladder, with sterile water (water that has been treated to remove bacteria and living organisms) vs Betadine also known as Povidone-Iodine (a medical grade cleaning solution) changes the rates of bacteria in the urine after a temporary catheter, or draining tube, is placed into the bladder. Chemical antiseptics, including Betadine, are the current standard of care. An additional goal of this study is to determine whether cleaning of the urethra, or external opening to the bladder, with sterile water vs betadine changes the amount of discomfort or pain patients experience with placement of a temporary catheter, or draining tube, in the bladder.

Design outcomes

Primary

MeasureTime frameDescription
BacteruriaWithin 2 weeks of the patients procedure dateBacteruria defined as the presence of bacteria within patient urine evaluated with urinalysis. Bacterial presence will be further characterized by colony forming unit count on urine culture.

Secondary

MeasureTime frameDescription
Urethral PainAt the time of catherizationUrethral pain at the time of catheterization rated by patients on a visual analog scale zero to ten with zero representing no pain and ten representing the worst pain of their life.
