Purpose. The following review focuses on the recent advancements in intravesical drug delivery, which brings added benefit to the therapy of detrusor overactivity and interstitial cystitis/painful bladder syndrome (IC/PBS). Results. Intravesical route is a preferred route of administration for restricting the action of extremely potent drugs like DMSO for(More)
PURPOSE To evaluate the effects of phosphodiesterase type 5 inhibitor (PDE5i) on urinary continence recovery after bilateral nerve-sparing radical prostatectomy (BNSRP). MATERIALS AND METHODS Between 2002 and 2012, 137 of 154 consecutive patients who underwent BNSRP in our institution retrospectively divided into 3 groups that included patients taking(More)
AIMS Stress urinary incontinence (SUI) is common in post-menopausal women. The present study therefore examined how aging and estrogen deficiency induced by ovariectomy (OVX) affect the urethral continence mechanism that prevents sneeze-induced SUI in rats. METHODS Young (3 months old) and middle-aged (12 months old) female rats underwent bilateral OVX or(More)
AIMS In order to clarify whether an alpha1A/D-adrenoceptor (α1 A/D-AR) antagonist, naftopidil, or a phosphodiesterase type 5 (PDE5) inhibitor, tadalafil, prevents bladder wall remodeling after spinal cord injury (SCI), we examined the bladder and urethral activity as well as ischemic and fibrotic changes in the bladder using SCI rats with or without(More)
AIMS To investigate the role of the glutamatergic pathway and its relationship to noradrenergic and serotonergic pathways in modulation of the urethral continence reflex during sneezing in rats. METHODS In female Sprague-Dawley rats under urethane anesthesia, the effects of an α-amino-3-hydroxy-5-meth-ylisoxazole-4-propionic acid (AMPA) glutamate receptor(More)
Magnetoencephalography (MEG) was used to measure the somatosensory evoked fields in six healthy males undergoing sacral surface therapeutic electrical stimulation, a recently introduced treatment for chronic urinary dysfunction. This study was performed to investigate the utility of MEG to optimize the stimulation parameters. Strong or weak electrical(More)
