Nelaton catheter, urological, various sizes

A Nelaton catheter is a type of urological catheter used for draining the bladder. It is a flexible, hollow, cylindrical tube made of medical-grade materials, such as latex or silicone, that is inserted into the bladder through the urethra. The Nelaton catheter is typically used for short-term bladder drainage in a hospital or outpatient setting, such as in cases of urinary retention, incontinence, or prior to certain medical procedures. The use of a sterile catheter helps to reduce the risk of infection and other complications associated with catheterization.
