The main types of urinary incontinence are shown in Table 1.
Main types of urinary incontinence 
Leakage on effort/exertion, or sneezing/coughing
Leakage with, or immediately after, need to pass urine Overactive bladder (OAB) is a subtype due to bladder muscle overactivity
|Mixed urinary incontinence||
Leakage associated with urgency plus exertion/effort or sneezing/coughing
Leakage due to inability to reach toilet in time
Incomplete bladder emptying causing overflow of urine when pressure increases on bladder e.g. coughing/sneezing
|Nocturnal enuresis (bedwetting in children)||
Leakage of bladder during sleep
New treatment under development at the Bionics Institute
Bionics Institute researchers are developing a medical device that aims to restore normal bladder control via electrical stimulation.
How does it work?
• The device comprises a tiny electrode array implanted onto the pelvic nerve using keyhole surgery
• The device is being designed to sense bladder pressure by monitoring the pelvic nerve
• Using a closed-loop system it will stimulate the pelvic nerve to void the bladder when pressure indicates fullness.
• Experiments are planned to explore the best way to delay urination, to ensure the bladder is voided at a socially acceptable time
• This stimulating and sensing device is being optimised and validated under a range of relevant conditions.
This device is safe and has been approved for use in clinical trials.
With your help, we can accelerate the evolution of this device, improving the lives of those with urinary incontinence.
