Question 1

Urge Incontinence S/sxs & Dx

Answer 1

• most common in elderly and nursing home residents
• overactive detrusor muscle → increased frequency and involuntary loss of urine
• S/sxs:
  
  • suddent urge to urinate (pts often unable to make it to restroom)
  • loss of LARGE volumes of urine with SMALL postvoid residual
  • nocturnal wetting
• Dx:
  
  • urodynamic study → shows how well the bladder, urethra and sphincter hold and release urine
    
    • will have increased bladder contractions during the filling phase

Question 2

Urge Incontinence Tx

Answer 2

• bladder training exercises: goal is to increase the amount of time between voiding
• limit fluids <2-2.5L/day
• avoid bladder irritants: chocolate, caffeine, acidic fruits and juices, spicy foods, and aspirin
• anticholinergic: oxybutynin, tolterodine, darifenacin, solifenacin, trospium, fesoterodine)
  
  • → reduce bladder irritability and contractility
  • SEs = retention, dry mouth, constipation, nausea, blurred vision, tachycardia, confusion, delirium, contraindicated in narrow angle glaucoma
• 3rd line = botox
• 4th line = neuromodulation-electrical sim → percutaneous tibial nerve stimulation

Question 3

Stress Incontinence S/sxs & Dx

Answer 3

Most common in women (after having multiple children)

• weakness of the pelvic diaphragm (pelvic floor) leads to loss of bladder support with resulting hypermobility of the bladder neck
• S/sxs:
  
  • involuntary loss of urine (only in spurts) during activities that increase the pressure of the abdominal cavity
    
    • cough, sneezing, weight lifting
• Dx: clinical diagnosis → rule out infx with urinalysis
  
  • urinary stress test

Question 4

Stress Incontinence Tx

Answer 4

• kegel exercises: 3-6 weeks of daily exercises, 200/day
