Detection of fluid entry into the urethra by electric impedance measurement: electric fluid bridge test.
The electric impedance of urine is considerably lower than that of urothelium: thus electrodes placed in the urethra can be used to show when urine penetrates the urethra during incontinence. This principle is presented as part of a possible diagnostic test of urethral incompetence.
