Some procedures call for cystoscopy
Dr. Gebhart: Is cystoscopy necessary in patients undergoing native tissue repair or abdominal approaches to prolapse, and should the experienced generalist have this skill?
Dr. Walters: If you are going to do prolapse surgery or surgery for stress urinary incontinence, you need to learn to do cystoscopy. Almost all specialists in urogynecology and urology would do a cystoscopy at the time of a native tissue prolapse repair, a mesh-augmented prolapse repair, or a sling procedure. Whether a generalist doing simple hysterectomies needs to do cystoscopy is controversial, and it is probably based on risk assessment of the kind of hysterectomy being done. Definitely, if you are doing prolapse repair, you probably should be doing cystoscopy at the same time.
Dr. Karram: I would take it further. For certain procedures, cystoscopy is standard of care. For example, if you are doing anything around the uterosacral ligaments, whether a McCall culdoplasty or uterosacral suspension, it is standard of care. It would be a difficult medical-legal defense issue if it was not done in those cases.
To Mark’s point, it is controversial whether universal cystoscopy should be performed on every hysterectomy or every anterior to posterior repair. We are not there yet, but certainly it is in your best interest to have a very low threshold, so if you think about doing cystoscopy, you should probably do it.
Dr. Gebhart: Is cystoscopy needed in sacrocolpopexy?
Dr. Ridgeway: We know from our own data that the risk of lower urinary tract injury is very low with sacrocolpopexy. Having said that, I agree with the position statement of the American Urogynecologic Society that says, “Universal cystoscopy should be performed at the time of all pelvic reconstruction surgeries, with the exception of operations solely for posterior compartment defects.”1
Dr. Gebhart: The reality is that we just want to identify if there is a problem or not at the time of the surgery. It does not mean you have to manage it. You could get your partner, your urologist, or another person with expertise to come in to help you.
Dr. Ridgeway: Absolutely, because intraoperative identification and treatment will prevent many unfavorable outcomes in the postoperative period.

Smoking’s effect on mesh
Dr. Gebhart: If a patient is a smoker and/or utilizes tobacco and you think she is a candidate for a sacrocolpopexy, are there any special considerations? How would you counsel that patient?
Dr. Walters: The risk of mesh erosion is high enough that I would try to not do any mesh prolapse repair in a woman who was a smoker, especially a heavy smoker. A more common situation is, would I put a polypropylene midurethral sling in that patient? I usually am willing to do that because it is still the best option compared with the no-mesh options. In a patient who would be a good candidate for sacrocolpopexy, I can usually do a no-mesh surgery and keep the risk low. I could always give the woman an option to quit smoking, but that tends not to be successful.
Dr. Gebhart: What is the risk of using mesh in a smoker?
Dr. Walters: An increased risk of erosion through the vaginal walls. I am not sure of the magnitude of risk, maybe 2 or 3 times higher. That is high enough that I probably would not take the risk except in unusual circumstances.
Dr. Ridgeway: A good amount of data show increased risk of mesh exposure for smokers. Those patients also tend to have a higher risk of prolapse recurrence because of coughing. Sacrocolpopexy is not my favorite operation to do in a smoker. I will work with the patient to quit, but often if it is the right operation, I will do it, with preoperative estrogen and appropriate conseling.
A role for mesh but not transvaginally
Dr. Gebhart: Is there still a role for vaginal mesh? While it is no longer being sold in the United States, could you fashion your own mesh for a prolapse procedure?
Dr. Walters: I can do pretty much everything I need to do without adding transvaginal mesh, and if I need a meshaugmented repair, then I would go with the sacrocolpopexy route. Having said that, data for hysteropexy do show that a mesh-augmented hysteropexy could have some advantages, whether you do it with a kit or some fashioned pieces of mesh. Most of the experiences with this are outside of the United States, so we need much more standardization of technique and tracking to answer that question.
Dr. Gebhart: Mickey, what are your thoughts regarding someone who thinks, “Mesh has been good for me, I want to stay with that. I’m going to cut my own mesh”? Are they assuming some liability now that companies are no longer marketing mesh for vaginal repair?
Dr. Karram: Unfortunately, I really think they are. It would be easy to be put in a legal corner and asked, the FDA felt that this should be pulled off the market, why are you still utilizing it? At the end of the day, what the FDA said was not inaccurate.
The studies have not shown a significant better outcome with mesh, and it is an extra intervention that, again, in the best of hands is going to have some issues. That is a dilemma many surgeons faced because they felt that that was their main way of treating prolapse—”they took away my way of successfully treating patients for years.” I do think it increases their medical-legal liability.
Dr. Ridgeway: I agree that it does increase medical-legal liability, and I can’t imagine a situation in which I would offer that. Dr. Gebhart: There are risks with all procedures, including slings for stress incontinence, but sling use is appropriate in appropriately counseled patients.
Dr. Ridgeway: Correct. I feel very strongly that the risk profile for the midurethral sling is very different from that for transvaginal mesh. Very large data sets in large groups of people support that the outcomes are favorable and the risk profile is low. Having said that, slings are not risk free, but living with severe incontinence is not risk free either.
