Urethral probe for urodynamic examinations

摘要

The uro-dynamic examination probe (1) has a vesical duct and a uretral duct with one end inserted into the patients urethra and the other for connection to a source of fluid (9) and a pressure gauge (5,7). The section and length of the ducts are selected so that when the vesical duct is connected to a pressure fluid source, pressure is increased in the distal end of each tube and the pressure differential at the tube ends measured by the gauges is less than five percent.
