Cystoscopy – a thin tube with a tiny camera is inserted in the urethra and used to see the inside of the urethra and bladder. Urodynamics – various techniques measure pressure in the bladder and the flow of urine.People are often asked to keep a diary for a day or more, up to a week, to record the pattern of voiding, noting times and the amounts of urine produced. Research projects that assess the efficacy of anti-incontinence therapies often quantify the extent of urinary incontinence. The methods include the 1-h pad test, measuring leakage volume; using a voiding diary, counting the number of incontinence episodes (leakage episodes) per day; and assessing of the strength of pelvic floor muscles, measuring the maximum vaginal squeeze pressure. Main types
There are 4 main types of urinary incontinence:

Stress incontinence, also known as effort incontinence, is essentially due to incomplete closure of the urinary sphincter, due to problems in the sphincter itself or insufficient strength of the pelvic floor muscles supporting it. This type of incontinence is when urine leaks during activities that increase intra-abdominal pressure, such as coughing, sneezing or bearing down. Urge incontinence is an involuntary loss of urine occurring while suddenly feeling the need or urge to urinate, usually secondary to overactive bladder syndrome. Overflow incontinence is the incontinence that happens suddenly without feeling an urge to urinate and without necessarily doing any physical activities. It is also known as under-active bladder syndrome.
Urodynamic testing seems to confirm that surgical restoration of vault prolapse can cure motor urge incontinence. Traditional suburethral sling operations are probably slightly better than open abdominal retropubic colposuspension and are probably slightly less effective than mid-urethral sling operations in reducing urinary incontinence in women, but it is still uncertain if any of the different types of traditional suburethral sling operations are better than others. Similarly, there is insufficient evidence to be certain about the effectiveness or safety of single-incision sling operations for urinary incontinence in women. Traditional suburethral slings may have a higher risk of surgical complications than minimally invasive slings but the risk of complications compared with other types of operation is still uncertain.Laparoscopic colposuspension (keyhole surgery through the abdomen) with sutures is as effective as open colposuspension for curing incontinence in women up to 18 months after surgery, but it is unclear whether there are fewer risk of complications during or after surgery. There is probably a higher risk of complications with traditional suburethral slings than with open abdominal retropubic suspension. The artificial urinary sphincter is an implantable device used to treat stress incontinence, mostly in men. The device is made of 2 or 3 parts: The pump, cuff, and balloon reservoir connected to each other by specialized tubes. The cuff wraps around the urethra and closes it. When the person wants to urinate, he presses the pump (implanted in the scrotum), to deflate the cuff, and allow the urine to pass. The cuff regains pressure within a few minutes to regain continence.
