Silicone urinary catheters differ from ordinary catheters in that they are made of high-quality silicone.
They are inserted into the bladder through the urethra to drain urine. After insertion, a balloon near the catheter tip secures the catheter in the bladder, preventing dislodgement. The drainage tube connects to a urine bag to collect urine.
Silicone urinary catheters are structurally classified into single-lumen and double-lumen catheters. Double-lumen catheters have an injection port for balloon inflation and an outlet.
Silicone urinary catheters are available in 11 sizes, ranging from F6 to F26, based on their outer diameter circumference.
