Objective: To evaluate the role of video-urodynamics (VUD) in the diagnosis of lower urinary tract voiding dysfunction.
Methods: From December 2008 to March 2010, 115 patients with lower urinary tract voiding dysfunction were included in our study. All patients underwent VUD studies.
Results: Neurogenic bladder was found in 37 patients, including 25 male patients and 12 female patients. Among these patients, 18 patients were detrusor areflexia (DA), 2 patients were overactive bladder (OAB), 10 patients were low compliance bladder with hydronephrosis and 7 patients were detrusor-external sphincter dyssynergia. Non-neurogenic voiding dysfunction was found in 59 patients, including 34 male patients and 25 female patients. Among these patients, bladder outlet obstruction was found in 33 patients, OAB in 4 patients, urethra stricture in 4 patients and sphincterismus in 3 patients. Seven patients receiving augmentation of bladder took second VUD examination, including 4 male patients and 3 female patients. One patient receiving Indiana pouch and one patient receiving ureter reimplantation all took VUD examination. Ten patients had basic normal bladder urethra function from VUD examination, including 6 male patients and 4 female patients.
Conclusion: From combination of pressure-flow figure and real time image, VUD examination provides precise evidence of diagnosis and treatment for lower urinary tract voiding dysfunction.
