Mayo Clinic Bladder Slings Surgery: What You Need To Know

The Mayo Clinic is a nonprofit organisation that provides expert, comprehensive care in clinical practice, education, and research. It offers sling surgeries, also known as stress incontinence surgeries, to treat urinary incontinence in patients. This procedure involves creating a hammock-like support for the urethra using a sling made from synthetic material or tissue from the patient's body. The Mayo Clinic also offers a single-incision mini-procedure, which involves fewer incisions, and conventional sling procedures for patients who have previously undergone sling surgery but still experience stress urinary incontinence.

Sling surgeries support the urethra using a hammock-like sling

While I could not find explicit information on whether Mayo Hospitals perform bladder sling surgeries, they have been mentioned in studies regarding sling surgeries. One study from 2019 discusses the advantages of stress urinary incontinence surgery, specifically noting the safety of midurethral slings. Another study from 2002 to 2012 compared transobturator sling surgery with retropubic sling procedures, finding that the latter had better long-term outcomes.

Sling surgeries are a common treatment for stress incontinence, which is the involuntary loss of urine during daily activities such as exercise, coughing, or sneezing. This condition is caused by sagging of the urethra or bladder neck, or problems with the muscular outlet of the bladder (sphincter). During sling surgery, a "sling" or "hammock" is created out of mesh or human tissue, which is placed under the urethra to lift and support it, preventing leaks. The sling can be made from the patient's own tissue, typically from the stomach or thigh, or from donor tissue in traditional surgeries. Alternatively, synthetic mesh material can be used in mid-urethral sling surgery.

There are several methods for performing sling surgery. The retropubic (TVT) method involves making small cuts inside the vagina under the urethra, as well as above the pubic bone. The sling is then inserted using a needle and placed under the urethra and behind the pubic bone. The transobturator method involves similar incisions but places the sling on each side of the labia. The single-incision mini method uses only one small cut in the vagina, with no stitches required as scar tissue will form to keep the sling in place. The traditional method involves making two cuts, one in the vagina and one in the belly, and then stretching the sling through the abdominal incision and stitching it to the stomach wall.

Sling surgeries are generally effective, with about 8 out of 10 women cured of stress urinary incontinence. However, there are potential complications, including difficulty urinating, new symptoms of urgency or incontinence, organ injury, internal bleeding, and infection. In rare cases, synthetic mesh may dissolve or erode, requiring additional surgery. Patients should be aware of these risks and discuss them with their healthcare provider before deciding on a sling surgery.

The sling is synthetic or made from tissue from the patient's body

Bladder sling surgery is a procedure to treat stress urinary incontinence. It involves placing a sling under the urethra and bladder neck to provide support and prevent leakage. The sling can be made from synthetic material or natural tissue from the patient's body.

Synthetic slings, also known as mid-urethral slings, are made from mesh material and are placed through a small incision in the vagina or groin, resulting in a shorter hospital stay and recovery time compared to natural tissue slings. The two types of synthetic mid-urethral sling insertion options are retropubic and transobturator. A retropubic sling is inserted behind the pubic bone, near other organs, while a transobturator sling is inserted through the groin without interfering with other organs.

Natural tissue slings, also known as pubovaginal or fascial slings, are made from the patient's own tissue, usually harvested from the rectus fascia (a dense fibrous material overlying the abdominal muscles) through an abdominal incision. The sling is placed under the bladder neck by making a separate incision in the vagina. This procedure is more invasive than synthetic sling surgery and requires a longer hospital stay and recovery period.

The Mayo Clinic, a nonprofit organisation providing clinical practice, education, and research, has conducted studies on stress urinary incontinence surgery. One retrospective study of 1,800 cases from 2002 to 2012 found that the need for additional surgery was higher after transobturator sling surgery compared to retropubic sling surgery. The study also reported extremely low complication rates for mid-urethral slings, with a reoperation rate of 3.2% due to problems with bladder emptying and 1.9% due to mesh exposure in the vagina.

Retropubic sling procedures have better long-term results than transobturator sling surgeries

The Mayo Clinic is a nonprofit organisation that provides expert, comprehensive care, as well as being committed to clinical practice, education, and research. The clinic has published studies on the advantages of stress urinary incontinence surgery.

A retrospective study of more than 1,800 cases at the Mayo Clinic from 2002 to 2012 found that the need for additional surgery was twice as high after a transobturator sling surgery compared to a retropubic sling procedure. Reoperation rates within eight years after surgery were 11.2% for patients in the transobturator group compared to 5.2% in the retropubic group. The failure rate for the transobturator procedure was even higher among women who had the sling combined with vaginal prolapse repair. This led Dr Emanuel Trabuco, a Mayo Clinic urogynecologist and the study's lead author, to conclude that the findings suggest that the retropubic procedure has better long-term results compared to the transobturator sling.

The retropubic sling procedure involves placing a mesh sling under the urethra and behind the pubic bone. On the other hand, the transobturator sling procedure places the mesh at a less acute angle by threading it through the thigh area.

While both procedures are considered safe with few complications, the retropubic approach has displayed higher efficacy than the transobturator method in some studies. One Swedish register-based study found that out of 2421 women who underwent surgery with a mid-urethral sling, those in the retropubic group reported higher cure rates, lower urgency urinary incontinence rates, and lower UDI-6 scores. This study also reported a subjective cure rate of 63.3% and improvement from 79.2% of participants, with no difference in safety between the two methods.

However, it is important to note that evidence regarding the long-term efficacy and safety of mid-urethral slings as a whole is scarce, and there is currently no clear evidence that one technique is more effective than the other. Advantages and disadvantages have been noted for both techniques, such as a higher risk of bladder injury with the retropubic approach and a higher risk of groin pain with the transobturator technique.

Midurethral slings have extremely low complication rates

Midurethral slings are a mainstay of stress urinary incontinence (SUI) treatment due to their efficacy and low complication rates. A study of 1,800 cases at the Mayo Clinic from 2002 to 2012 found that the need for additional surgery was twice as high after a transobturator sling surgery (11.2%) compared with a retropubic sling procedure (5.2%). However, the overall complication rates that necessitated reoperation were extremely low: 3.2% due to problems with bladder emptying and 1.9% due to mesh exposure in the vagina.

While rare, major complications of midurethral slings are more common than reported in the literature. These can include urethral and bladder perforations, which may present with mild urinary symptoms and thus be under-diagnosed and under-reported. In such cases, additional reconstructive surgery is often required.

A systematic review of the literature identified 33 randomized controlled trials reporting data on complication rates. The analysis showed that complication rates were similar after tension-free vaginal tape (TVT) and Burch colposuspension, except for bladder perforation, which was more common after TVT. Reoperation rates were significantly higher after Burch colposuspension. TVT and pubovaginal sling procedures had comparable complication rates.

The most common indication for sling removal was vaginal pain. RP slings had a higher risk of suprapubic pain, while TOT slings had a higher risk of groin pain. Patients with a history of SIS had a higher incidence of urethral erosion. TOT removal had the highest intraoperative complication rate.

Surgeries carry risks including urinary and vaginal issues

While bladder slings are a common treatment for stress urinary incontinence, surgeries carry risks, including urinary and vaginal issues. Bladder sling surgery is generally well tolerated, but mesh complications, erosion, and organ perforation can occur. These complications can arise during surgery or years later.

Mesh slings are more likely to cause complications than slings made of native tissues. Synthetic mesh can cause problems, including infection and long-term pain. According to the American College of Obstetricians and Gynecologists, these risks are either not present or greatly reduced. Pain is one of the most common bladder sling surgery complications, persisting in 42.3% of patients who underwent revision surgery. There is also an up to 13% chance of recurring urinary tract infections. Other pervasive risks include mesh erosion and urinary retention issues.

Bladder and bowel perforation after mesh placement can be serious and lead to infections and other problems. Bladder perforation occurs when the mesh or surgical tools puncture the bladder during surgery, causing pain, bleeding, and urinary tract infections. In most cases, bladder perforation does not cause long-term injury, but it can sometimes require surgery to repair the bladder. A punctured bowel is a more severe type of perforation that can cause life-threatening infections and may require surgery to remove the mesh and repair the bowel.

The risk of mesh extrusion and erosion varies depending on the type of sling used. Mesh extrusion refers to the mesh forcing its way out of the vagina, while erosion occurs when the mesh wears through the vaginal wall and into the vagina. Management of bladder erosion can be done endoscopically, laparoscopically, or through a retropubic or vaginal approach.

The true incidence of obstruction and voiding dysfunction after incontinence surgery is unknown. However, data from large series indicate that the intervention rate for these complications following midurethral slings is between 1% and 2%. Obstructive symptoms include urinary retention or incomplete emptying, obstructive voiding symptoms, and storage symptoms such as frequency, urgency, and urge incontinence.
