In urology, a Foley catheter is one of many types of urinary catheters (UC). The Foley UC was named after Frederic Foley , who produced the original design in 1929. Foleys are indwelling UC, often referred to as an IDCs (sometimes IDUCs).
Common indications for urinary catheterization include acute or chronic urinary retention (which can damage the kidneys) from conditions such as benign prostatic hyperplasia, orthopedic procedures that may limit a patient's movement, the need for accurate monitoring of input and output (such as in an ICU), urinary incontinence that may compromise the ability to heal wounds, and the effects of ...
Male external catheters are designed to be worn 24/7 and changed daily – and can be used by men with both light and severe incontinence. Male external catheters come in several sizes and lengths to accommodate anatomical variation. It is very important that the male external catheter/urisheath fits well – both the diameter and the length.
The French size is a measure of the outer diameter of a catheter (not internal drainage channel, or inner diameter). So, for example, if a two-way catheter of 20 Fr is compared to a 20 Fr three-way catheter, they both have the same external diameter but the two-way catheter will have a larger drainage channel than the three-way.
Upon completion of the internal incision(s), the instrument is withdrawn and an appropriately sized Foley catheter will be inserted through the repair and into the urinary bladder, and locked into place by filling its balloon (positioned inside of the bladder near the urethral junction) with sterile water. The Foley catheter serves two purposes ...
Pigtail catheter is a non-selective catheter with multiple side holes that can deliver large volumes of contrast into a blood vessel for imaging purposes. [29] Cobra catheter is a selective catheter used to catheterise downgoing vessels in the abdomen. Cobra catheters move forward by pushing and are removed by pulling. [30]
