متن کاملNeurophysiological modeling of voiding in rats: urethral nerve response to urethral pressure and flow.
In male urethan-anesthetized rats, activity was measured in nerves that run over the proximal urethra. The urethral nerve response to stepwise urethral perfusion could be described by a four-parameter model (fit error <6%). At the onset of perfusion, the urethra was closed and the pressure increased with the infused volume. The nerve activity (NA) increased linearly with this inserted volume to...
متن کاملEffects of thyrotropin-releasing hormone on urethral closure pressure in females with voiding dysfunction.
INTRODUCTION To evaluate the effect of intravenous thyrotropin releasing hormone (TRH) on the urethral closure pressure (UCP). MATERIALS AND METHODS Twenty-two female patients with either bladder outlet obstruction (BOO) or detrusor under activity were included in this study. They divided into two study and control groups randomly. Twelve patients in study group received 200 microgr of TRH in...
متن کاملSpinal Transection Alters External Urethral Sphincter Activity during Spontaneous Voiding in Freely Moving Rats.
The rat is a commonly used model for the study of lower urinary tract function before and after spinal cord injury. We have previously reported that in unanesthetized freely moving rats, although phasic external urethral sphincter (EUS) activity (bursting) is most common during micturition, productive voiding can occur in the absence of bursting, which differs from results seen in anesthetized ...
متن کاملTransrectal voiding sonourethrography for diagnosis of a prostatic urethral calculus.
bstructive uropathy is a common clinical problem, and urethral calculi constitute the least common form of calculous disease leading to obstructive uropathy. Urethral calculi may originate anywhere in the urinary tract, usually the bladder, and then migrate to the urethra. The clinical presentation is variable. Patients may have acute retention, dysuria, or a weak urine stream.1 Sonography is a...
