Uro Dynamic Study Indication
Urodynamics are a means of evaluating the pressure-flow relationship between the bladder and the urethra for the purpose of defining the functional status of the lower urinary tract. The ultimate goal of urodynamics is to aid in the correct diagnosis of lower urinary tract dusfunction based upon its pathophysiology. Urodynamic studies should assess both the filling and storage phase, as well as the voiding phase of bladder and urethral function. In addition, provocative tests can be added to try to recreate symptoms and assess pertinent characteristics of urinary leakage.
Simple urodynamic tests involve performing noninvasive uroflow studies, obtaining a postvoid residual (PVR) urine measurements, and performing single-channel cystometrography (CMG).
