The urethral sphincter is considered an integral part of maintaining urinary continence, and it is important to understand its role in some conditions: Stress urinary incontinence is a common problem related to the function of the urethral sphincter. Weak pelvic floor muscles, intrinsic sphincter damage, or damage to the surrounding nerves and ...
A rhabdosphincter (from Greek rhabdos meaning "rod") is a sphincter consisting of striated muscle fibres. [1] The muscle is a part of the external urethral sphincter that continues superiorly as a trough-like extension running vertically across the anterior aspect of the prostate to reach the neck of the bladder. [2] [3]
This is a small sphincter of striated muscle tissue and is in healthy males, under voluntary control. Relaxing the urethral sphincter allows the urine in the upper urethra to enter the penis properly and thus empty the urinary bladder. Physiologically, urination involves coordination between the central, autonomic, and somatic nervous systems ...
Urinary retention [10] Overflow incontinence (occurs in chronic retention) [10] Episodes of near retention [10] As the symptoms are common and non-specific, LUTS is not necessarily a reason to suspect prostate cancer. [7] Large studies of patients have also failed to show any correlation between lower urinary tract symptoms and a specific ...
Dissection of prostate showing the bulbourethral glands within the fibers of the external urethral sphincter just underneath the prostate. The bulbourethral glands are compound tubulo-alveolar glands, each approximately the size of a pea in humans. In chimpanzees, they are not visible during dissection, but can be found on microscopic ...
Urodynamic testing or urodynamics is a study that assesses how the bladder and urethra are performing their job of storing and releasing urine. Urodynamic tests can help explain symptoms such as: incontinence [1] frequent urination; sudden, strong urges to urinate but nothing comes out; problems starting a urine stream; painful urination
Urinary incontinence* is leakage of urine, usually due to incompetence of the urethral sphincter in adult dogs and ectopic ureter (a congenital condition in which the ureter enters the urinary tract posterior to the urethral sphincter) in puppies. In adult dogs it is most commonly seen in large spayed females.
It is most common among large breed, spayed female dogs, but it can occur in intact females, male dogs, and cats. [17] Urethral sphincter incompetence is the primary cause of urinary incontinence. [17] It is important to seek veterinary aid if urinary incontinence presents frequently. Medication
