  • Classification of Voiding Dysfunction: Simplified
    All voiding dysfunctions are classified as:
    • Failures of Fill/Store which can be due to:
      • Bladder
      • Urethra/outlet
      • Both
    • Failure of Emptying which can be due to:
      • Bladder
      • Urethra/outlet
      • Both
  • Classification of Incontinence
    • Extraurethral
      • Fistula (vesicovaginal, ureterovaginal, urethrovaginal)
      • Ectopic ureter
    • Urethral
      • Functional
        • Because of physical disability
        • Due to lack of awareness or concern
      • Bladder abnormalities
        • Overactivity
          • Involuntary contractions
          • Decreased compliance
          • Hypersensitivity with incontinence
      • Outlet abnormalities
        • Genuine stress incontinence
        • Intrinsic sphincter deficiency
        • Urethral instability
        • Post-void dribbling
          • Urethral diverticulum
          • Vaginal pooling of urine
      • Overflow incontinence

SELF-ASSESSMENT QUESTIONS

  1. Regardless of differences regarding physiologic and pharmacologic details, what would most experts agree are the requirements for normal bladder filling and storage? Discuss the main points relating to the anatomy, neurophysiology, and neuropharmacology of each of these factors.
  2. Regardless of differences regarding physiologic and pharmacologic details, what would most experts agree are the requirements for normal bladder emptying and voiding? Discuss the main points relating to the anatomy, neurophysiology, and neuropharmacology of each of these factors.
  3. Broadly generalize the differences between the autonomic and somatic nervous systems. Discuss the terms parasympathetic and sympathetic.
  4. What are the primary neurotransmitters released at postganglionic, parasympathetic, and sympathetic effector sites in the lower urinary tract? Discuss the distribution and the results of activation of the cholinergic and adrenergic receptors in lower urinary tract smooth muscle.
  5. Discuss the differences in organization of the micturition reflex in a normal adult and in an adult with a T10 spinal cord transection following spinal shock.
  6. Categorize each urodynamic study (flowmetry, residual urine, filling and voiding cystometry, detrusor and abdominal [Valsalva] leak point pressures, urethral profilometry, and electromyography) as to what they characterize with respect to bladder and outlet activity during the filling and storage and emptying and voiding phases of micturition.
  7. Characterize the most common types of voiding dysfunction seen with the following neurologic injury(ies) and disease(s) in terms of sensation, bladder activity, smooth sphincter activity, striated sphincter activity: (1) cerebrovascular accident; (2) Parkinson's disease; (3) multiple sclerosis; (4) suprasacral spinal cord injury; (5) sacral spinal cord injury; (6) radical pelvic surgery; and (7) diabetes.

  11. Discuss the classic differentiation between genuine stress urinary incontinence and intrinsic sphincter deficiency and the therapeutic implications of each.
  12. Discuss the normal support mechanism(s) of the bladder neck and proximal urethra in the female and the various theories of pathophysiology of hypermobility related stress incontinence.
  13. Discuss the possibilities and practicalities of pharmacologic therapy for (1) bladder overactivity; (2) decreased outlet resistance; (3) increased outlet resistance; and (4) decreased bladder contractility.
