Comparison Between Ambulatory and Conventional Urodynamics of the Modified Orthotopic Hautmann Neobladder

Purpose: The aim of the present study was to determine the diagnostic accuracy of conventional and ambulatory urodynamic studies (UDS) in estimating neobladder function. Methods: We evaluated 32 patients who underwent radical cystectomy and orthotopic Hautmann W neobladder with Abol-Enein-Ghoneim uretero-intestinal anastomosis for bladder cancer. The patients were initially examined by using both conventional and ambulatory UDS. Results: Conventional UDS detected a very high mean intravesical pressure at maximum capacity (53.7±17.5 cm H2O). By contrast, the mean intravesical pressure detected by using ambulatory UDS (which reflects the dominant pattern of pressure variation during filling) was significantly lower (34.4±5.2 cm H2O, P
