Chronic Urinary Retention

About

  • When the bladder does not empty properly

Potential Causes

  • Obstruction in the urinary tract
  • Enlarged prostate gland can press on the urethra (in men)
  • Cystocele: A bladder that sags (in women)
  • Rectocele: Rectum that sags into the back wall of the vagina (in women)
  • Drugs including antihistamines, antispasmodics, anticholinergics and tricyclic antidepressants that can change the way the bladder muscle works
  • Urethral stricture
  • Urinary stones
  • Catheter use
  • Nerve problems that interfere with signals from the brain to the bladder
  • Nerves can be damaged from vaginal childbirth, spinal cord injuries/infections, diabetes, stroke, multiple sclerosis, pelvic injury/trauma and benign prostatic hyperplasia
  • If the bladder tries to release but cannot due to weak pelvic floor muscles or the sphincter not relaxing at the right time

Symptoms

  • A struggle to start the flow of urine
  • Weak flow
  • Feeling the need to go, but cannot start
  • Feeling the need to urinate right after you’ve gone

Diagnosis

  • Medical history: To address past and current health issues and over-the-counter and prescription drugs being taken
  • Physical exam: Of the lower abdomen (for men and women) and prostate check (for men)
  • Urinalysis: To test for infection/blood/abnormalities
  • Bladder ultrasound: To show how much urine is still in the bladder post-urination
  • Cystoscopy: To look at the lining of your urethra and bladder to check for urethral stricture, a blockage caused by a stone, an enlarged prostate or a tumour
  • CT scan: Can help find stones or anything else blocking the flow of urine
  • Catheter tests: Can determine urine flow rate and how well the bladder empties
  • Prostate-specific Antigen (PSA) blood test: To screen for prostate cancer
  • Electromyography (EMG): Uses sensors to measure electrical activity of muscles and nerves in and near the bladder and urethral sphincter

Treatment

  • Enlarged Prostate
    • Oral Medications: Alpha-blockers and 5-alpha reductase inhibitors to help shrink the prostate
    • Laser therapy: To break up the blockage
    • Surgery: Transurethral resection of the prostate to remove a section of the prostate
  • Cystocele/Rectocele
    • Pelvic Physiotherapy: To strengthen the pelvic floor muscles
    • Vaginal Pessary: Insertion of vaginal pessary (ring) to support the bladder
    • Estrogen Therapy: For post-menopausal women
    • Surgery: To lift the sagging bladder/rectum
  • Urethral Stricture
    • Using catheters and balloons to open the urethra
    • Stent: Can prop open a closed urethra (in men)
    • Surgery: Using a knife/laser to make a cut to open the stricture
  • Nerve-related
    • Self-catheterization
