The pressure sensor is for use in the long term weekly monitoring of full serial bladder (vesical) pressure in patients that perform regular clean intermittent catheterizations (CIC). Regular once per week long term monitoring of bladder pressure in patients at risk for developing high bladder pressures and urinary incontinence associated with, urinary tract infections (UTI), vesicoureteral reflux and renal insufficiency. The most significant source of urologic morbidity and mortality in patients with spinal conditions where CIC is used is renal failure secondary to upper tract deterioration from high bladder pressures.
Cystometry (CMG) is an integral part in the urologic evaluation of patients prior to the use of this device. At no time is this device to be used in place of CMGs for diagnostics. Patients with CMG leak point pressures greater than 40 cm H20 are at significant risk for upper tract deterioration. The frequency and timing of CMG urodynamic studies in patients with spinal injuries continues to be controversial, but use of this device may insure that full CMGs or other suitable diagnostics are performed on a timely basis by the patients attending physician.

§ 876.1620 Urodynamics measurement system.
(a)
Identification. A urodynamics measurement system is a device used to measure volume and pressure in the urinary bladder when it is filled through a catheter with carbon dioxide or water. The device controls the supply of carbon dioxide or water and may also record the electrical activity of the muscles associated with urination. The device system may include transducers, electronic signal conditioning and display equipment, a catheter withdrawal device to enable a urethral pressure profile to be obtained, and special catheters for urethral profilometry and electrodes for electromyography. This generic type of device includes the cystometric gas (carbon dioxide) device, the cystometric hydrualic device, and the electrical recording cystometer, but excludes any device that uses air to fill the bladder.(b)
Classification. Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 876.9.
