[Modification of the test pressure-flow for evaluation of detrusor contractility in absence of urination].
The aim of the study was design and validation of the test for examination of detrusor contractility in the absence of urination. The method consists in registration of detrusor pressure in maximal speed of urinary flow in the course of artificial urination using Foley's catheter. Urethral resistance was modeled by raising drainage up to 40 cm above the level of the symphysis which was adjusted and found optimal in 48 of 179 examinees. The method allowed to select patients with infravesical obstruction (IVO) and normal detrusor contractility (n = 36) as well as patients with hypocontractility without IVO (n = 12). The test "pressure-flow" in artificial urination evaluates detrusor contractility in patients unable to urinate. The test distinquishes patients with normal detrusor contractility and those with different degree of its impairment. This is important in assessment and prognosis of deficient urination.
