Foley Catheter - Structure & Parts, Indications, Procedure, Suprapubic Catheterization, Risks

The urinary tract system produces, stores, and excretes urine from the body.
Under normal circumstances, kidneys produce about 1 ml of urine per minute.
The capacity of the bladder is variable.
A healthy bladder can usually retain about 350 to 500 ml of urine.
Three sets of muscles control the flow of urine from the bladder via the urethra.
The internal and external sphincters, which are formed by involuntary and voluntary muscles respectively, and pelvic floor muscles.
In people with impaired urinary flow either due to retention or incontinence, a safe, and reliable system is required to collect and contain urine.
This is where the urinary catheter comes into play.
