Explanation:

Some individuals may experience difficulty with getting urine out of their system probably due to certain infection, old age or other related problems such that passing out urinary waste becomes a major problem. When this occurs and persist, the way out may be to employ the use of a device called catheter which is a tube which leads out of the lower abdomen and help drain the bladder. This process of creating a narrow passage which is artificially drilled to aid the passage of urine from the urinary bladder is called Cystostomy.
