Urodynamic Pattern Distribution Among Aged Male Patients With Lower Urinary Tract Symptoms Suggestive of Bladder Outlet Obstruction

A Chinese Medicine Formula “Xian‐Jia‐Tang” for Treating Bladder Outlet Obstruction by Improving Urodynamics and Inhibiting Oxidative Stress through Potassium Channels

“…As a nuclear transcription factor, HIF- α was always highly expressed in anoxic environment, which was an effective marker for hypoxia [27]. In BOO, high pressure in bladder wall always occurred, which could lead to reducing blood supply to the bladder due to oppressed artery [28]. Although subsequent process of urination can relieve the ischemia and hypoxia of bladder tissue, ischemia-reperfusion always enhances the bladder injury [29].…”

Clinical and urodynamic effects of baclofen in women with functional bladder outlet obstruction: Preliminary report

“…The criterion of Qmax to define female BOO, however, ranges from 11 mL/s to 15 mL/s, and PdetQmax ranges from 21 to 50 cmH 2 O, and female BOO nomogram has been reported . Apart from Qmax and PdetQmax, some studies suggest that increased volume of the striated sphincter and especially paradoxical overactivity of the EMG during the voiding phase are the characteristic findings of functional BOO . Although needle EMG, which can specifically show activity of the periurethral striated muscle, was not used in our urodynamic laboratory, surface electrodes demonstrated statistically significant improvement in EMG electrical activity at the voiding phase in some patients after baclofen treatment (Fig.…”

Recent research on the role of urodynamic study in the diagnosis and treatment of male lower urinary tract symptoms and urinary incontinence

“…Another video-urodynamic study in young men with LUTS showed that the most common urodynamic abnormalities were BOO (42.5%), dysfunctional voiding (28.7%), DU (11.5%), and DO (8.1%) [27]. In 1984 men older than 45 years with LUTS suggestive of BOO, several different urodynamic patterns were noted other than BOO, including DO, sphincteric overactivity, low compliance, and DU [28]. …”
