Urethral Bulking Injections in London
Urethral bulking injections are a minimally invasive treatment for stress urinary incontinence. They work by adding support around the urethra, the tube that carries urine out of the body, to help reduce leakage when you cough, laugh, exercise or lift.
For suitable people, this can be a day-case option with a shorter recovery than more extensive surgery.

What are urethral bulking injections?
Urethral bulking is a treatment for stress urinary incontinence. Stress incontinence is leakage caused by pressure on the bladder, such as when coughing, sneezing, laughing, exercising or lifting.
During the procedure, a soft bulking material is injected into the wall of the urethra. This provides additional support and can help the urethra remain closed more effectively when pressure increases.
Bulking injections may be considered if pelvic floor rehabilitation has not provided enough improvement, particularly for people who would prefer to avoid surgery or are not suited to a more extensive procedure.
The treatment is usually carried out as a day case. It is less invasive than sling surgery and recovery is generally quicker. However, the benefits may not last as long as surgical treatment and some people may need repeat injections over time.
Your consultant will explain how bulking injections compare with other options for stress incontinence, including the potential benefits, limitations and risks.

How it works
Bulking injections aim to reduce stress leakage by improving support around the urethra.

A soft material is injected into the urethral wall to help the urethra close more effectively during activities that put pressure on the bladder.
May reduce leakage
With additional support around the urethra, leakage caused by coughing, laughing, sneezing or exercise may improve.
Minimally invasive treatment
The procedure is usually carried out as a day case and does not involve major surgery.
