Pharmacological inhibition Pathophysiology: decreased contractility secondary to receptor blockade of neural efferents or afferents discount tricor 160 mg otc cholesterol in butter. Loss of sense of fullness/urge incontinence without appreciation of “desire to void cheap 160mg tricor otc cholesterol test kit. Decreased bladder outlet and pelvic floor sensation Pathophysiology: denervation order genuine femara on line, myopathy, behavioral, pharmacological causing decreased ability to identify/contract/coordinate. Increased sensation of the bladder/bladder outlet Pathophysiology: neuropathic, inflammatory, mucosal permeability defect, psychogenic, afferent amplification. Increased sensation of the pelvic floor/bladder outlet Pathophysiology: neuromuscular myalgia, neuropathic, inflammatory, psychogenic. The overactive outlet: Failure to empty the bladder may be due to elevated outlet resistance or to impaired contractility of the bladder. The most commonly observed clinical etiology of elevated outlet resistance is iatrogenic, obstruction following incontinence surgery. Neurogenic outlet obstruction, commonly seen following injury to the suprasacral spinal cord, is due to a loss of coordination between the bladder and sphincter (detrusor sphincter dyssynergia). The paradoxical failure of the outlet to relax during voiding may result in anatomical obstruction to flow or to inhibition of the initiation or completion of the detrusor contraction. Contraction of the pelvic floor or sphincter is a normal response for bladder inhibition but, when pathological, may be classified as pseudodyssynergia (voluntary or behavioral) or true dyssynergia (neurogenic). The relaxation of the urethral sphincter during voiding and dyssynergic activity in spinal cord injury has been documented. It is not known whether the specific anatomical areas of the urethra or pelvic floor (sphincter urethra, compressor urethra, urethrovaginal sphincter, bulbocavernosus, anal sphincter, levator complex) act in unison, individually, or at all in detrusor 391 inhibition in normal subjects. Therefore, the central and peripheral nervous systems mediate bladder control through complex voluntary pathways and reflex arcs. Central efferent control of the bladder smooth musculature is mediated by afferent activity from the detrusor musculature and bladder mucosa (facilitatory) and the reflex and voluntary contractions of the pelvic floor and sphincter musculature (inhibitory). The underactive bladder: Traditional concepts of detrusor underactivity have focused on either efferent innervation or myogenic dysfunction. By contrast, contemporary views emphasize the importance of the neural control mechanisms, particularly the afferent system, which can fail to potentiate detrusor contraction, leading to premature termination of the voiding reflex. To void efficiently, a feedforward mechanism by which urinary flow in the urethra helps to enhance and maintain adequate contractile function of the bladder until the bladder is empty is required. Sensory information is fed back to the motor system at several levels of control between the end organ and brain cortex.

The examiner may also assess for anal and vaginal tone order 160 mg tricor mastercard cholesterol test kit nz, voluntary tightening of anus buy discount tricor 160mg online cholesterol yahoo answers, and bulbocavernosus reflexes in women with suspected neurological disorders [41] 25mg indocin visa. It is vital that the patient is aware of the purpose of the exam and understands that she has the final authority to terminate the physical examination, to ask questions, to have control over who is in attendance, and to understand the extent of the assessment. Inclusion of the sexual partner, with permission of the patient, is advantageous and provides needed patient support. Allowing the patient to observe any pathology via digital photography is often therapeutic, allowing, for the first time in many cases, an illustration and connection of a detected physical abnormality with the sexual health problem. If a genital sexual pain history exists, the patient should point with her finger to the location/s of the discomfort during the physical examination [34]. Independent of the gender of the examining health-care clinician, it is strongly recommended that a female chaperone the health-care clinician during the entirety of the examination. If a chaperone is declined then this should be documented contemporaneously, preferably with witnessing. The patient should be placed in the lithotomy position and the examining health-care clinician should use vulvoscopy (Figure 64. In addition, warming the room creates a more relaxed environment in which the patient will feel more comfortable. External Examination The first part of the examination involves inspection of the vulva and labia majora. Two gloved fingers are placed on either side of the clitoral shaft, and using an upward force in the cephalic direction, the prepuce is retracted to gain full exposure of the glans clitoris, corona, and right and left frenulum emanating at 5:00 and 7:00 from the posterior portion of the glans clitoris (Figure 64. The labia minora are inspected for labial resorption and for their ability to meet at the midline posterior fourchette (Figure 64. The maximal labial width is recorded to compare pre- and posthormone supplementation. Using gauze to maximally retract the labia minora, the labial–hymenal junction (Hart’s Line) is identified. The Q-tip cotton swab is placed at multiple locations on the vestibule, which is defined as the tissue medial to Hart’s line (Figure 64. A Q-tip cotton swab test is performed, gently applying pressure on the minor vestibular glands (Figure 64. The examining health-care clinician should use vulvoscopy with magnified vision and a focused light source. The patient should be placed in the lithotomy position and wear a sheet to cover her lower torso.
