Monitoring Detrusor Oxygenation and Hemodynamics Noninvasively during Dysfunctional Voiding
Advances in Urology, 2012 The current literature indicates that lower urinary tract symptoms (LUTSs) related to benign prostatic hyperplasia (BPH) have a heterogeneous pathophysiology. Pressure flow studies (UDSs) remain the gold standard evaluation methodology for such patients.
