Urodynamics Equipment

Urodynamics equipment used to study the functions of the bladder and urethra using measurements of pressure and flow. Urine flow tests are an integral part of the urodynamic study, however flowmeters "autonomous" are mainly used for uroflowmetry.

The urodynamic study included the following measurements:

To study the free flow of urine, the patient empties urine into a machine that measures the rate and pattern of urine flow. There are two types of flow meters on urine and transducer rotating disk weight. Also, sometimes perineal electromyography is performed within the muscles during urination.

During filling cystometry, the bladder pressure and abdominal pressure are measured. Abdominal pressure is recorded to monitor any changes that may affect the bladder pressure.

When performing a filling and emptying cystometry, the bladder should be actively filled by the infusion of saline or a radio opaque solution and bladder, and pressure to the abdomen and bladder are measured continuously through the inclusion of catheters. When the bladder is full, empty cystometry performed: while the patient is recorded pressure urine flow. Sometimes simultaneously recorded electromyographic signals. The data is analyzed and generated pressure flow curves.

Sometimes, ambulatory monitoring of bladder held in special schools urodynamics. During ambulatory monitoring, bladder and abdominal pressure are recorded, but allow natural filling of the bladder.

With the help of a special catheter is performed measuring urethral pressure profile. This catheter is slowly withdrawn through the urethra, while the liquid is poured through it slowly. Urethral pressure is recorded continuously at the tip of the catheter. This type of medical equipment typically use a small motor device, which removes the catheter fixed speed.

Urodynamic systems are usually designed for clinical use mobile and can be worn within a department. Some systems are mounted on a special car and include a desktop computer.

The bladder and abdominal pressure can be measured with various types of pressure transducers that can be water-filled catheters connected to an external pressure sensor. Solid state sensors at the tip of the catheter provides reliable measurement of the pressure.
