Hi,
Bulkamid surgery is a simple, low risk procedure. It also provides a fast return to normal activities and has a fast recovery rate. It has been used on women with stress incontinence for the past 10 years. From what I have found online, few complications have been reported, however, as with any invasive procedure, complications may occur. Check with your Doctor beforehand about any possible risks and complications.
Botox is generally known to be a safe method, however it can have possible side effects or cause an allergic reaction for some people. Always discuss with your Doctor beforehand to ensure a botox injection is suitable for you. You should inform them of any conditions or allergies you have beforehand. It is not recommended for people who cannot empty their bladder on their own.
