A catheter (a hollow tube, often with an inflatable balloon tip)
may be inserted into the urinary bladder when there is a urinary

unconscious patients (due to surgical anesthesia, coma, etc.), or
for any other problem in which the bladder needs to be kept empty
(decompressed) and urinary flow assured.
