How is it done?

• This procedure is done under a spinal / general anaesthetic, as decided by the anaesthetist.
• The legs will be elevated into the lithotomy position.
• A small incision is made in the vagina. The sling is placed around the pubic bone and brought to the skin at the inner thigh, with a small incision.
• The sling is placed tension free.
• The bladder will be inspected with a Cystoscopy to exclude any injuries to the bladder wall.
• If you have a suspected Intrinsic Sphyncter Deficiency (ISD), the sling may be placed tighter
• The wounds are closed with dissolvable sutures and/or skin glue.
• A local anaesthetic is given for pain relief.
• A urinary catheter is placed for 24hrs.
• A vaginal plug will also be placed.
• The catheter and plug will be removed early the next morning.
• The patient’s urine output will be measured each time they urinate and the residual will be measured. (Patients will be required to do this up to 3 times.)
• If the residual amount of urine is more than 1/3 of the total bladder capacity, the patient may have to self catheterise, until the residual volume is acceptable.
• Prophylactic antibiotics will be given to prevent infection.

What to expect after the procedure?

• Any anaesthetic has its risks and the anaesthetist will explain all such risks.
• Complications: hemorrhaging, requiring blood transfusion <1%; bladder perforation, requiring an open repair <1%.
• Patients will wake up with a catheter in the urethra and bladder. This will remain in the bladder for 24 hrs.
• Inner thigh discomfort/pain will persist for a few days but this will subside / settle.
• If you cannot urinate after 2-3 attempts, the sling may be readjusted.
• You may be required to self catheterize for a week or two.
• If there is no improvement the sling may be cut, to allow spontaneous urination
• NB! Each person is unique and for this reason symptoms may vary!

What next?

• Patients will have a trial of void without catheter the next day.
• Patients will be discharged as soon as they can completely empty the bladder.
• Patients may be required to self catheterize for a week or two.
• Patients may initially suffer from urge incontinence but this will improve within the next 6 weeks.
