Neurogenic bladder dysfunction can involve a malfunctioning urethral sphincter. [8] Urge incontinence can happen when the urethra cannot hold the urine in as the bladder contracts uncontrollably. [9] Retrograde ejaculation can occur in men when the internal urethral sphincter fails to adequately contract during ejaculation. [3]
Large studies of patients have also failed to show any correlation between lower urinary tract symptoms and a specific diagnosis. [11] Also, recently a report of lower urinary tract symptoms even with malignant features in the prostate failed to be associated with prostate cancer after further laboratory investigation of the biopsy. [10]
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 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. [7] [10] Voiding urine begins with voluntary relaxation of the external urethral sphincter.
In acute cases of urinary retention where associated symptoms in the lumbar spine are present such as pain, numbness (saddle anesthesia), parasthesias, decreased anal sphincter tone, or altered deep tendon reflexes, an MRI of the lumbar spine should be considered to further assess cauda equina syndrome.

Common symptoms of pelvic floor dysfunction in men include: Difficulty urinating, even when trying to “push” with your muscles. Urinary incontinence (involuntary urinary leakage), especially ...
Symptoms reported by the patient are an unreliable guide to the underlying dysfunction of the lower urinary tract. [ citation needed ] The purpose of urodynamics is to provide objective confirmation of the pathology that a patient's symptoms would suggest.
When of sudden onset, symptoms include an inability to urinate and lower abdominal pain. [21] When of gradual onset, symptoms may include loss of bladder control, mild lower abdominal pain, and a weak urine stream. [21] Those with long-term problems are at risk of urinary tract infections. [21]
