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 ...
The external urethral sphincter is a striated muscle that allows voluntary control over urination. [5] The internal sphincter, formed by the involuntary smooth muscles lining the bladder neck and urethra, receives its nerve supply by the sympathetic division of the autonomic nervous system. [6] The internal sphincter is present both in males ...
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 ...
The internal urethral sphincter is a urethral sphincter muscle which constricts the internal urethral orifice. It is located at the junction of the urethra with the urinary bladder and is continuous with the detrusor muscle , [ 1 ] [ 2 ] but anatomically and functionally fully independent from it. [ 3 ]
Urethral syndrome is defined as symptoms suggestive of a lower urinary tract infection but in the absence of significant bacteriuria with a conventional pathogen. [1] It is a diagnosis of exclusion in patients with dysuria and frequency without demonstrable infection. [2] In women, vaginitis should also be ruled out. [3]
The muscle helps maintain continence of urine along with the internal urethral sphincter which is under control of the autonomic nervous system.The external sphincter muscle prevents urine leakage as the muscle is tonically contracted via somatic fibers that originate in Onuf's nucleus and pass through sacral spinal nerves S2-S4 then the pudendal nerve to synapse on the muscle.
