A Foley catheter helps in draining urine from the bladder into a urine collection bag. It is a thin tube constructed of soft and flexible material that is inserted into the bladder to completely empty it. Foley urinary catheter features a small retention balloon which is inflated in the bladder to hold the catheter in place. Retention balloon prevents falling out of the catheter from the bladder and lets the user perform his daily activities with freedom. Since the catheter can be left in the bladder for an extended period, it is also called an indwelling catheter.
Foley indwelling catheters are usually categorized into three broad categories, namely, two-way Foley catheters, three-way Foley catheters and Foley catheters with a temperature sensor. A brief description of these categories is given below:
A two-way catheter has two channels and a retention balloon. One channel is used to drain out urine, and another channel is used to inflate the retention balloon. Inflated retention balloon securely holds the Foley urethral catheter in place. It is widely used for the management of urinary dysfunction.
A three-way catheter contains three channels. Like a two-way catheter, one channel is used to drain out urine and another to inflate the retention balloon. The third channel helps provide continuous bladder irrigation to clear blood clots or debris. A three-way Foley catheter is used in the case of prostate tumor, bleeding from the bladder or after urological surgery.
A foley catheter with an integrated temperature sensor near the tip is used to measure the temperature of urine inside the bladder. It also helps in determining core body temperature. This temperature sensing catheter is used for intensive care and some surgical procedures.
The selection of an appropriate Foley catheter is essential for successful Foley catheterization. When buying a Foley catheter, a few points to consider are its material, size, length, foley balloon size, and tip design should be kept in mind.
Material: The choice of catheter material should be what suits your body type and minimizes the risk of urethral irritation.
Length: Foley catheters come in three lengths, short, standard, and pediatric.
Balloon: Foley catheters come in 3 balloon sizes: 5cc, 10cc, and 30cc. Choosing a larger balloon size than required may result in dragging the catheter due to the water weight in larger balloons. The larger balloon sits higher in the bladder and can increase the risk of getting urethral damage. Under or over-inflation of the balloon can block the drainage eyes and cause bladder spasms. Therefore, the balloon should be inflated according to the guidelines of the manufacturer.
Tip Design: Foley urinary catheter is categorized into two types, depending on the type of catheter tips: Nelaton catheter and Tiemann catheter.
Charrier size: The diameter of the Foley catheter is measured in Charriere (Ch or CH) or French (Fr or FR) size. It indicates the external diameter of the catheter. Choosing the smallest possible size that offers adequate drainage is always recommended because a larger diameter may cause urethral spasms and irritation. Foley catheters with larger charrier size can be used for supra-pubic catheterization to prevent blockage.
Bard Bardia 2-Way Silicone-Elastomer Coated Foley Catheter is designed with a hydrophobic material rejecting moisture. This rigid latex catheter is coated with Silicone Elastomer to help reduce urethral irritation and maximize stiffness without compromising flexibility. It is designed with two opposing eyes for drainage. It is rigid latex, is easier to insert, and reduces urethral irritation.

Poiesis Duette Dual-Balloon Two-Way Foley Catheter is a 100% silicone, self-retaining balloon catheter that provides safe and comfortable means of catheterization. Its innovative dual balloon design has the edge over traditional Foley catheters, whose uncushioned tips and drainage aspiration can cause bladder trauma. A second distal balloon on the tip of the catheter adds another layer of comprehensive infection control. It has a subsumed Tip that is inserted and removed just like a standard Foley catheter. The drainage eyes located between two balloons minimize aspiration damage.
