Two-way urethral Foley catheter with balloon
A two-way urethral Foley catheter is a type of indwelling urinary catheter that is inserted into the bladder through the urethra to allow for continuous drainage of urine. The catheter has two lumen or channels, one for draining urine and the other for inflating and deflating a balloon that helps to keep the catheter in place within the bladder. The balloon is usually filled with sterile water and can be inflated to a specific volume to ensure proper placement of the catheter and prevent it from being dislodged. Two-way urethral Foley catheters are commonly used in hospital settings for patients who require long-term bladder drainage, such as those undergoing surgery, those with urinary incontinence, or those with certain medical conditions that affect bladder function.
