Urodynamic testing or urodynamics is a study that assesses how the bladder and urethra are performing their job of storing and releasing urine. Urodynamic tests can help explain symptoms such as: incontinence frequent urination sudden, strong urges to urinate but nothing comes out problems starting a urine stream painful urination problems emptying the bladder completely recurrent urinary tract infections Urodynamic tests are usually performed in Urology, Gynecology, OB/GYN, Internal medicine, and Primary care offices. Urodynamics will provide the physician with the information necessary to diagnose the cause and nature of a patients incontinence, thus giving the best treatment options available. Urodynamics is typically conducted by urologists or urogynecologists. The output of urodynamic catheter is given to multichannel digital pressure transducers and through a data acqisition device it is given to a computer. The software was developed under Lab view software. The machine is made in just Rs 30,000 compared to the commercially available machine costing Rs 30 lac. Various parameters studied are: P ves: Bladder pressure Pabd: Abdominal pressure measured by the rectal catheter. Pdet: Pdet = Pves - Pabd Detrusor leak point pressure (DLPP): The lowest detrusor pressure at which urine leakage occurs in the absence of either a detrusor contraction or increase in abdominal pressure. Pura: Urethral pressure MUCP: Mean urethral closure pressure Q: Flow rate of fluid in ml/second. EMG: Electromyography of sphincter.
