videourodynamic

Videourodynamics is a diagnostic medical procedure used to evaluate bladder and urethral function. It combines urodynamic testing with real-time imaging, typically fluoroscopy or ultrasound, to visualize the flow of urine and the behavior of the bladder and urethra during filling and voiding. This allows physicians to assess pressure, flow rates, and the coordination of the muscles involved in bladder storage and emptying.

The procedure involves inserting a small catheter into the bladder to fill it with a contrast liquid, which shows up on the imaging. Another catheter may be placed in the rectum to measure abdominal pressure, or a urethral catheter may be used to measure urethral pressure. Sensors are attached to monitor pressures and flow rates. Patients are then asked to perform various maneuvers, such as coughing, straining, and attempting to urinate, while the contrast liquid is filling the bladder and as they attempt to empty it.

Videourodynamics is particularly useful in diagnosing complex urinary incontinence, urinary retention, and other lower urinary tract symptoms that may not be fully explained by conventional urodynamic studies alone. It helps identify problems such as bladder outlet obstruction, detrusor overactivity, or poor bladder contractility. The detailed information gathered allows for a more precise diagnosis and can guide the selection of appropriate treatment options, which may include medication, behavioral therapies, or surgical interventions. The procedure is generally safe, though it carries risks associated with catheterization and imaging, such as urinary tract infections or minor discomfort.
