Transobturator midurethral sling
What is a transobturator midurethral sling?
A transobturator midurethral sling is a procedure to correct stress urinary incontinence (SUI). SUI is a type of urinary incontinence that is defined as involuntary leakage of urine related to an increase in intraabdominal pressure that occurs during sneezing, laughing, coughing or exercise. It is a very common condition that occurs in 1 in 3 women.
SUI occurs when the supports of the urethral are weakened allowing for hypermobility or instability of the urethral. The midurethral sling utilizes a small piece of mesh to support the midurethral and ultimately decreases hypermobility. The transobturator approach to the midurethral sling describes the course of the sling which curves around the ischiopubic rami and out the groin. It is typically the first line choice of slings when dealing with SUI.
How is the procedure performed?
Transobturator midurethral slings are performed by making a small incision in the vaginal and two small incisions in the groin. After periurethral tunnels are created, a special trocar (sling placement device) is utilized to place the mesh under the midurethra and exit the groin incisions. Cystoscopy is typically performed afterwards to confirm that no injury to the bladder was sustained. It is a very effective treatment and is recognized as the standard of care for treatment of stress urinary incontinence
What should I expect?
After initial consultation with Dr. Kow, you may be asked to undergo some bladder testing (urodynamics) prior to surgery. Prior to surgery, you will need to attend a preoperative visit with Dr. Kow and draw some basic lab work. Should you need surgical clearance, you will be asked to obtain this prior to surgery.
The surgical procedure takes less than 30 minutes to perform. You will have two small incisions in the groin region after surgery. If performed by itself, it is an outpatient procedure and does not require an overnight stay. However, it is often performed at the time of other surgeries such as prolapse surgery. If it is performed with other procedures, you may require an overnight stay and be discharged the following day.
Overall recovery time includes six weeks with some activity restrictions, however patients are often able to return to a normal routine shortly after surgery. Restrictions including the following:
- No heavy lifting of more than 10 lbs for 6 weeks
- No tub baths for 6 weeks
- No sexual intercourse for 6 weeks
- No driving while on narcotic pain medications
What are the risks of the procedure?
Complications from a transobturator midurethral sling are typically very low. However with every procedure there always some risks including anesthesia problems, postoperative pain, intraoperative bleeding, infection, blood clots and damage to adjacent organs. With regards to a transobturator midurethral sling, some specific risks include the following:
- 5-10% risk of postoperative urinary tract infection
- 1% risk of mesh exposure
- 1% of temporary groin pain
This procedure is a safe and effective surgery that is the treatment of choice for correction of stress urinary incontinence. While there has been confusion regarding the use of mesh, a recent position statement by the American Urogynecologic Society and the Society of Urodynamics, Female Pelvic Medicine & Urogenital Reconstruction summarizes the safety and efficacy of the procedure.
