Over the last 30 years, surgical correction of the common condition pelvic organ prolapse (POP) and stress urinary incontinence (SUI) has become so routine and straightforward that many gynecologists and urogynecologists choose surgery as their first choice for treating these conditions, withholding it only from the riskiest patients or from those who, for a variety of reasons, do not choose surgery. Moreover, as generalist gynecologists increasingly refer patients with POP or incontinence to their urogynecologist colleagues, they increasingly lack the skills, or have not been trained, to use conservative treatment strategies for these disorders. Thus, pessaries—devices constructed of inert plastic, silicone, or latex and placed inside the vagina to support prolapsed pelvic structures—frequently are not part of the general gynecologist’s armamentarium.
When properly selected, however, pessaries used for indicated purposes and correctly fitted are an excellent, inexpensive, low-risk, and noninvasive tool that can provide immediate relief not only of POP but also of SUI and defecatory difficulties. As an alternative to surgery, pessaries are especially valuable, because the other major nonsurgical modality for treatment of POP and incontinence—pelvic floor muscle training—often is not covered by insurance (making it expensive for patients), takes many weekly sessions to complete (which can make access challenging), and frequently is not readily available.1
POP is very common. An estimated 15% to 30% of women in North America have some degree of prolapse, and more than 500,000 surgeries for this condition are performed in the United States each year.2 Risk factors for POP include:
- vaginal childbirth, especially higher parity
- advancing age
- high body mass index (BMI)
- prior hysterectomy
- raised intra-abdominal pressure, such as from obesity, chronic cough, or heavy lifting.
In addition to the discomfort caused by the herniation of pelvic and vaginal structures, POP also is associated with urinary incontinence (73%), urinary urgency and frequency (86%), and fecal incontinence (31%).3
Moreover, according to the US Census Bureau, the number of American women aged 65 or older will double to more than 40 million by 2030.4 This will greatly increase the population of women at risk for POP who may be candidates for pessary use. It therefore behooves gynecologists to become familiar with the correct usage, fitting, and maintenance of this effective, nonsurgical mode of treatment for POP.
In this article, I discuss why pessaries are a good option for many patients with POP, review the types of pessaries available, and offer guidance on how to choose the right pessary for an individual patient’s needs. In addition, the box at the end of this article provides an interesting timeline of pessary history dating back to antiquity.
Next month in Part 2 of this article, I cover how to fit a pessary; device aftercare; potential complications of use; and effectiveness of pessaries for POP, SUI, preterm labor prevention, and defecatory disorders.
