A urinary blockage can be painful and dangerous if not treated promptly. By inserting a catheter into the bladder, the urine is released and the pressure subsides. A blockage can also occur in the ureters. The ureters are the tubes that connect the kidneys to the bladder. In this case, a simple catheter will not relieve the problem.
Women often have transient blockage during childbirth.
This is more likely if they receive an epidural pain killer. Sometimes adult diapers may be used for those who cannot control their urination. Other times a catheter may be used. Usually a catheter is left in the urethra for a short time only. People with long term problems, such as paralysis, may need a permanent catheter.
