Urodynamic investigations



Urodynamics has been around since the mid to late 19th century when catheters were first passed into the bladder and connected to a column of water (manometer). Electronics and computing have revolutionised the field, principally by allowing the real-time subtraction of pressures that is required.

The drawing shows an early attempt at cystometry. In modern times the staffing level can be halved and the dress code is slightly less formal.
