Teams of urodynamic urodynamic computers are used for the study of 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 autonomous flow meters are mainly used for the flowmetry. The urodynamic study includes the following measurements: tests of free flow of urine cystometry flow curve of urine and pressure in the bladder urethral pressure measurement studies of monitoring outpatient with notebooks urodynamic studies are performed when the patient has one of the following symptoms: urination frequent incontinence problems in emptying of the bladder. Urodynamic team includes a flow meter which for studies of pressure / flow is possible. To free urine flow study, patient discharges urine in a machine that measures the rate and pattern of urine flow. There are two types of urine flow meters: spinning wheel and weight transducer. Plus, sometimes is the perineal electromyography within muscles during urination.
During the filling cystometry, bladder pressure and abdominal pressure are measures. Abdominal pressure is registered to control any changes which might influence the bladder pressure. When performing a cystometry of filling and emptying, the bladder must be actively filled by the infusion of saline solution or an opaque solution of radio and the bladder; and the abdomen and bladder pressure are measured continuously through the insertion of catheters. When the bladder is full, is done emptying cystometry: while the patient urine flow rate pressure is recorded. Sometimes the electromyographic signals are recorded at the same time. The data are analyzed and pressure flow curves are generated. Sometimes, bladder ambulatory monitoring is carried out in special centres of urodynamics.
During the ambulatory monitoring, bladder and abdominal pressure is they register, but allowed the natural bladder filling. Urethral pressure profile measurement is performed with the help of a special catheter. This catheter is slowly removed through the urethra, while liquid is infused slowly through it. Urethral pressure is continuously recorded in the tip of the catheter. This type of medical equipment normally used a small device with engine, which the fixed speed catheter removed. Urodynamic systems are generally designed for mobile clinical utilization and can be ported within a Department. Some systems are mounted on a special truck and include a desktop computer. The bladder and abdominal pressure can be measured with various types of pressure transducers that can be a few water-filled catheters connected to an external pressure sensor. Sensors of solid-state in the catheter tip provide reliable measurement of pressure.
