- Urine leak on movement, coughing, laughing, squatting, etc.
- Weak pelvic floor muscles
- Common in women with children, especially after menopause
How is stress incontinence treated?
Treatments of stress incontinence include physiotherapy, oestrogen cream and duloxetine. Surgical treatment is also possible with TVT/colposuspension.
When does urinary retention with overflow incontinence occur?
When the bladder outlet is too strong
What are the characteristics of urinary retention with overflow incontinence?
- Poor urine flow, double voiding,
- Hesitancy, post micturition dribbling
- Blockage to urethra
- Older men with BPH
- Only type of incontinence more common in males
How is urinary retention with overflow incontinence treated?
Treatment can be done with alpha blockers, anti-androgens or surgical TURP.
Catheterisation may be required, often done suprapubically.
When does urge incontinence occur?
When the bladder muscles are too strong
What are the characteristics of urge incontinence?
- Detrusor contracts at low volumes
- Sudden urge to pass urine immediately
- Patients often know every public toilet
- Can be caused by bladder stones or stroke

Bladder retraining involves getting the patient to void every 90-120mins, regardless of urge to void.
When does a neuropathic bladder occur?
When the bladder muscle is underactive
What are the characteristics of a neuropathic bladder?

- Secondary to neurological disease, typically multiple sclerosis or stroke
- Can also be secondary to prolonged cathetarisation
- No awareness of bladder filling resulting in overflow incontinence
How is the neuropathic bladder treated?
Medical treatments are usually unsatisfactory but parasympathomimetics may help
Catheterisation is the only effective treatment
What type of incontinence occurs when the bladder muscle is overactive?
Urge incontinence
What type of incontinence occurs when the bladder muscle is under active?
