Favorable outcome of pubovaginal slings for geriatric women with stress incontinence

Traditionally pubovaginal slings have been associated with a greater risk of immediate morbidity and prolonged voiding dysfunction compared to other stress incontinence repairs. Because elderly patients already have inherently greater perioperative risk and prevalence of innate voiding dysfunction, there is some reluctance to construct slings in this age group. We examined the outcome of pubovaginal sling in elderly women versus younger controls to determine whether this concern is justified.

We retrospectively analyzed the outcome of 19 geriatric women older than 70 years who underwent a pubovaginal sling procedure between 1992 and 1995, and compared the findings to those of 77 younger control women with a mean followup of 22 months. All women had video urodynamically proved stress incontinence due to intrinsic sphincter deficiency and many had coexistent bladder instability symptoms. Women with neurogenic causes for incontinence were excluded from the study.

Stress incontinence resolved in 100% of geriatric and 97% of control women. Preoperative instability symptoms, including urge incontinence, improved in more than 50% of patients in both groups. De novo instability symptoms arose in 10% of women in each group but were generally controlled with anticholinergics. Efficient voiding resumed within a mean of 16 days in both groups.

The morbidity and success rates of pubovaginal sling surgery in the elderly compare favorably to those in younger women. Advanced age alone would not dissuade us from constructing a pubovaginal sling when indicated.
