When we talk about surgical treatment for stress incontinence, we are dealing with an anatomic situation; we are trying to restore normal anatomy without altering normal urethral function; namely, you don’t want to foul up someone’s ability to urinate or over-obstruct the bladder neck and lead to involuntary bladder contractions that are iatrogenic. The problem is that genuine stress incontinence is not just an anatomic condition. In all patients who have genuine stress incontinence, we know that there are also concurrent local peripheral neurologic changes in the pudendal nerve and in the ability of the levator ani muscles to contract. People don’t develop prolapse and don’t develop incontinence unless they have some dysfunction, typically, of the levator musculature beforehand. We aren’t going to fix that with most of our surgeries. We have to realize that sometimes we are not just doing the anatomic and we are compromising for some of these other factors.

Looking at anterior colporrhaphies and Kelly-Kennedy plications, objective cures in the literature range from thirty to ninety percent with subjective cure rates paralleling this. There is very poor longevity in most series that look at these operations - Kelly-Kennedy plication specifically - five years later show success rates below fifty percent. It is not so bad at creating de novo detrusor instability; this occurs probably only in about five percent of the cases. Definitive study done 15 to 16 years ago by Stewart, Stanton and London presented a prospective randomized trial of Burch procedures versus Kelly-Kennedy plications with 25 patients in each group. What they found was that at six months, with objective follow up, thirty-six percent had objective cure for the Kelly-Kennedy plication and eighty-four percent objective cure rate for their Burch procedures with all comers.

Talking about retropubic anti-incontinence operations, the prototype that most of us are familiar with is the Burch procedure or the MMK. The modified Burch procedure is an operation whose goal is to resupport the anterior vaginal wall and thus indirectly resupport the proximal urethra. We suture a mobile structure, the anterior vaginal wall, to an immobile source of support, Cooper’s ligament, the iliopectineal line, or in the case of an MMK, we suture to the pubic symphysis. The goal here is to resupport the proximal urethra. When we do, the literature suggests that there are objective cure rates ranging from eighty to ninety-five percent, depending on the population that you are operating on, with subjective cure rates that are just a little bit better. The great thing about the Burch procedure that most of us love is the excellent longevity. There are objective studies in the literature that I will show you that go out 10 and even 12 years with excellent long-term success. De novo detrusor instability - the creation of new urge incontinence and involuntary bladder contractions - in one study we did, occurred in eight percent of all patients that we operated on.

The modified Burch procedure involves the use of permanent sutures. In 1961, John Burch described the use of absorbable sutures; here we place one suture at the bladder neck, 2 cm lateral to the bladder neck on either side and then another pair distal to this. Here, we are just dermabrading and elevating the bladder neck superomedially off of the endopelvic connective tissue of the anterior vaginal wall. You can identify the bladder most easily and reliably by looking for the inferior vesical vein. If you are unsure, you can always fill the bladder retrograde or, if you don’t have access to a Foley to do that, you can stick a 60-cc syringe with a needle on it into the dome of the bladder, if you don’t want to open the bladder, and just inflate it with 60 cc of fluid. If the patient is in reverse Trendelenburg, you will start to see the inferior border of the bladder and then you can unocclude the Foley and drain it out to see where you are. You’d like to end up with two pairs of sutures - some people use three - about 1.5 to 2.0 cm lateral to the bladder neck so you don’t compromise the inferior vesical vein and artery, as well as the autonomic nerve supply that comes along with them to the proximal urethra and these go up through Cooper’s ligament, which runs from the lateral aspect of the pubic symphysis along the medial superior border of the pubic ramus. What this does is lifts a hammock of vagina and suture up to Cooper’s ligament on either side to stabilize the proximal urethra. So when we cough and strain, the pressure will compress the anterior urethral wall against the posterior urethral wall against a good solid back-stop of vagina.
