Leaking Havoc: Diagnosing And Treating Female Stress Urinary Incontinence

March 4, 2017

Andrew Siegel, MD  3/4/17

This is the completion of a blog entry uploaded last week entitled “Leaking Havoc: Female Stress Incontinence.”

How is Stress Urinary Incontinence (SUI) diagnosed and evaluated?

Listening carefully to the patient is usually sufficient to make the diagnosis of SUI, the typical complaint being: “Doc, I leak urine when I sneeze, cough and exercise.”

After hearing the details of the patient’s problem, the next step is a pelvic examination. The issue with an exam with legs-up-in-stirrups is that this is NOT the position in which SUI typically occurs, since SUI is usually provoked by standing, exertion and physical activities. For this reason, the exam must be performed using straining or coughing forcefully enough to demonstrate the SUI.

The pelvic examination is done after the patient empties her bladder. The exam involves observation, passage of a small catheter (a narrow hollow tube) into the bladder, a speculum exam and a digital exam.

Inspection determines tissue health and the presence of urethral movement with straining. After menopause, typical changes include thinning of the vaginal skin, redness, irritation, etc. The ridges and folds within the vagina that are present in younger women (rugae) tend to disappear.

A small catheter is passed into the bladder to determine how much urine remains, to obtain a urine culture in the event that urinalysis suggests infection and to determine urethral angulation. With the catheter in place, the angle that the urethra makes with the horizontal is measured. The catheter is typically parallel with the horizontal at rest. The patient is asked to strain and the angulation is again measured, recording the change in urethral angulation that occurs between resting and straining. Urethral angulation with straining (hyper-mobility) is a sign of loss of urethral support, which often is seen with SUI. The vagina is carefully inspected for other manifestations of pelvic organ prolapse (dropped bladder, rectum, uterus) that can accompany the SUI.

Finally, a digital examination is performed to assess vaginal tone and pelvic muscle strength (rated on a scale from 0-5). A bimanual exam (combined internal and external exam in which the pelvic organs are felt between internal and external examining fingers) checks for the presence of pelvic masses.

Depending on circumstances, tests to further evaluate SUI may be used, including an endoscopic inspection of the lining of the bladder and urethra (cystoscopy), sophisticated functional tests of bladder storage and emptying (urodynamics) and, on occasion, imaging tests (bladder fluoroscopy).                   

How is SUI managed?

There are a variety of treatment options for SUI, ranging from non-invasive strategies to surgery. There are no effective medications for SUI. If there is not an adequate response to first-line, non-invasive, conservative measures, surgery becomes an appropriate consideration. However, it is always sensible to initially use a conservative approach that is cost-effective, natural, uses few resources and is free from side effects.

Kegel Exercises for SUI

Kegels have emerged from obscure to mainstream…In fact the 2017 Oscar “swag bag” included a pelvic floor device called “The Elvie,” reviewed in my book THE KEGEL FIX.

Combating SUI demands contracting one’s pelvic floor muscles (PFMs) strongly, rapidly and ultimately, reflexively. The goal of Kegels, a.k.a. pelvic floor muscle training (PFMT) is to increase PFM strength, power, endurance and coordination to improve urethral support and closure.

Who Knew? PFMT has the potential to improve or cure SUI in those who suffer with the problem and prevent it in those who do not have it.

The cough reflex is an automatic contraction of the PFMs above and beyond their resting tone when one coughs. This squeezes the urethra shut to help prevent leakage. This is nature’s way of protection against incontinence with a sudden increase in abdominal pressure, a defense against cough-related SUI. An extension of this principle is to exercise the PFMs to amplify strength and power to allow earlier activation and more robust contraction.

PFMT increases PFM bulk and thickness, reducing the number of SUI episodes. Additionally, PFMT improves urethral support at rest and with straining, diminishing the urethral hyper-mobility that is characteristic of SUI. It also permits earlier activation of the PFMs when coughing, more rapid repeated PFM contractions and more durable PFM contractions between coughs.

Who Knew? PFMT can cure or considerably improve 60-70% of women who suffer with SUI. The benefits persist for many years, as long as the exercises are adhered to on an ongoing basis. PFMT is equally effective for pre-menopausal and post-menopausal women with SUI.

Who Knew? PFMT is most effective in women with mild or mild-moderate SUI. Chances are that if the SUI is moderate-severe, PFMT will be less effective. However, if not cured, the SUI can be improved, and that might be sufficient.

Once the PFMs are conditioned via PFMT, it is vital to apply the improved conditioning on a practical basis. The cough reflex can be replicated—voluntarily—when one is in situations other than actual coughing that induce SUI. In order to do so, one needs to be attentive to the triggers that provoke the SUI. By actively contracting the PFMs immediately prior to the trigger exposure, the SUI can be improved or prevented. For example, if changing position from sitting to standing results in SUI, consciously performing a brisk PFM contraction—an intense contraction for 2-5 seconds prior to and during transitioning from sitting to standing—should “clamp the urethra” and help control the problem. Such bracing of the PFMs can be a highly effective means of managing SUI and when practiced diligently can become automatic (a reflex behavior).

More Non-Invasive Strategies to Improve SUI

Manage the condition that provokes the SUI: Since discrete triggers often provoke SUI (e.g., when asthma causes wheezing, seasonal allergies cause sneezing, or when tobacco use, bronchitis, sinusitis, or post-nasal drip cause coughing), by managing the underlying condition, the SUI can be avoided.

Moderate fluid intake: With a sudden increase in abdominal pressure, there will tend to be more SUI when there are larger volumes in the bladder (although SUI can occur even immediately after urinating). Since there is a direct relationship between fluid intake and urine production, any moderation in fluid intake will decrease the volume of urine in the bladder and potentially improve the SUI. The key is to find the right balance to diminish the SUI, yet avoid dehydration. Since caffeinated beverages and alcohol increase urine volume, it is best to limit exposure (caffeine is present in coffee, tea, cola and even chocolate has a caffeine-like ingredient).

Urinate regularly: Based on the premise that there tends to be more SUI when there are greater volumes in the bladder, by emptying the bladder more frequently, SUI can be better controlled. Urinating on a two-hour basis is usually effective, although the specific timetable needs to be individually tailored. Voluntary urinary frequency is more desirable than involuntary SUI. An extension of this principle is to empty one’s bladder immediately before any activity that is likely to induce the SUI.

Maintain a healthy weight: Extra pounds can worsen SUI by increasing abdominal pressure and placing a greater load on the pelvic floor and bladder. Even a modest weight loss may improve SUI.

Who Knew? Bearing the burden of unnecessary pounds adversely affects many body parts. As much as obesity puts a great strain on the knees that support the body’s weight, so it does on the PFM.

Exercise: Being physically active can go a long way towards maintaining general fitness and helping improve SUI. In general, exercises that emphasize the core muscles—particularly Pilates and yoga—are most helpful for SUI. Unfortunately, and ironically, it is exercise that often provokes SUI.

Tobacco cessation: Tobacco causes bronchial irritation and coughing that provoke SUI. Additionally, chemical constituents of tobacco constrict blood vessels, impair blood flow, decrease tissue oxygenation and promote inflammation, negatively affecting function of the bladder, urethra and PFMs. By eliminating tobacco, SUI can be significantly improved.

Maintain bowel regularity: Achieving bowel regularity may improve SUI and prevent it from progressing. A rectum full of stool can adversely affect urinary control by putting internal pressure on the bladder and urethra. Additionally, chronic straining with bowel movements—similar in many ways to being in “labor” every day—can have a cumulative effect in weakening PFMs and can be a key factor in the development of SUI. To promote healthy bowel function, exercise daily and increase fiber intake by eating whole grains, fruits and vegetables.

The tampon trick: If SUI occurs under very predictable circumstances—e.g., during tennis, golf or jogging—a strategically placed tampon can be a friend. The tampon is not used for absorption purposes, but to support the urethra. By positioning the tampon in the vagina directly under the urethra, it acts as a space-occupying backboard. The tampon does not need to be positioned as deeply as it would be for menstruation, but just within the vagina. This may allow one to pursue activities without the need for a pad. Poise has come out with “Impressa,” a tampon available in three sizes designed specifically for SUI. It is placed via an applicator and can be worn for up to eight hours. In Australia and the UK, “Contiform,” a self-inserted, foldable intra-vaginal device that is shaped like a hollow tampon, is often used to help manage SUI.

Surgical Management of SUI: Mid-urethral sling

If conservative measures fail to sufficiently improve SUI, there are solutions. A relatively simple outpatient procedure—the mid-urethral sling—is the implantation of a synthetic tape between the urethra and vagina to recreate the “backboard” of urethral support that is defective. This creates a “hammock” to provide support and to allow compression and pinching of the urethra with any activity that increases abdominal pressure.

The sling procedure is performed via a small vaginal incision. The permanent material used for the sling is polypropylene tape, the same material as used by general surgeons to repair groin hernias. Mid-urethral refers to the placement of the sling beneath the mid-urethra, the channel that leads from the bladder to the urinary opening. Sling refers to the configuration created when the tape is firmly anchored to the soft tissues of the pelvis after being placed underneath the urethra. The sling procedure has a 85-90% cure rate for SUI.

Urethral Bulking Agents: Alternative To Stress Incontinence Surgery

Stress Urinary Incontinence (SUI)

SUI is a common condition that affects one in three women during their lifetimes, most often young or middle-aged women, although it can happen at any age. An involuntary spurt of urine occurs at times of sudden increases in abdominal pressure.  This can happen with coughing, sneezing, laughing, jumping or exercise. It can even happen with walking, changing position from sitting to standing or during sex.

SUI most often occurs because the tissues that support the urethra (the channel that conducts urine from the bladder) have weakened and no longer provide an adequate “backboard.” This allows the urethra to be pushed down and out of position at times of sudden increases in abdominal pressure, a condition known as urethral hyper-mobility. The key inciting factors are pregnancy, labor and delivery, particularly traumatic vaginal deliveries of large babies.

Although the predominant cause of SUI is inadequate urethral support, it may also be caused by a weakened or damaged urethra itself, a condition known as sphincter dysfunction. Risk factors for this are menopause, prior pelvic surgery, nerve damage, radiation and pelvic trauma. A severely compromised urethral sphincter causes significant urinary leakage with minimal activities and typically results in “gravitational” incontinence, a profound urinary leakage that accompanies positional change. In this situation the sphincter does not provide sufficient closure to pinch the urethra closed.

Useful analogy: Sphincter dysfunction is similar to a situation in which a sink faucet is leaky because of a brittle washer that has lost the suppleness to provide closure.

First-line Treatment For SUI: Pelvic Floor Muscle (PFM) Training (Kegels)

It is important to know that you can tap into the powers of your PFM and harness the natural reflex that inhibits stress urinary incontinence. Combatting SUI demands that the PFM contract strongly, rapidly and ultimately, reflexively. The goal of Kegels is to increase PFM strength, power, endurance and coordination to improve the urethral support and closure mechanism. This has the potential to improve or cure SUI in those who suffer with the problem and prevent it in those who do not have it.

Kegel exercises are most effective in women with mild or mild-moderate SUI. Kegels increase PFM bulk and thickness, including the sphincter mechanism, reducing the number of SUI episodes. Additionally, Kegels improve urethral support at rest and with straining, diminishing the urethral hyper-mobility that is characteristic of SUI. It also permits earlier activation of the PFM when coughing, more rapid repeated PFM contractions and more durable PFM contractions between coughs. PFM training can cure or considerably improve 60-70% of women who suffer with SUI. The benefits persist for many years, as long as the exercises are adhered to on an ongoing basis.

Urethral Bulking Agents

The “gold standard” treatment of SUI that does not respond to conservative measures is a mid-urethral sling, a surgical procedure that provides support and a “backboard” to the urethra.  Cure or significant improvement is in the 85-90% range with sling surgery.  An alternative to the sling surgery is the injection of a urethral bulking agent.

Urethral bulking agents are typically used for SUI due to weakened or poorly functional sphincter muscles.  A special material—a bulking agent—is injected into the tissues around the urethra in an effort to “plump” up the urethra to help provide closure to it, with the goal of improving urinary control. The material works by bulking up the layer of the urethra immediately under the inner urethral lining, providing closure of the urethra via compression. This outpatient procedure is simple to perform and generally takes only a few minutes. In theory, it is similar to the lip injections that are used by plastic surgeon in order to plump up the lips and make them appear fuller, suppler and more sensuous.

The urethral bulking agent procedure is done under direct visual control using a small, lighted scope (cystoscope) that is inserted into the urethra. The bulking material is injected into the tissue immediately under the urethral lining while the plumping and closure of the urethra is observed. Several treatments may be necessary for lasting results.

There are three materials that are FDA-approved bulking agents: carbon-coated beads suspended in a water gel (Durasphere); calcium hydroxylapatite (Coaptite); and silicone microparticles (Macroplastique).

For whom are bulking agents appropriate?

  • Women with SUI primarily due to sphincter dysfunction
  • Women who are too elderly or frail or have too many medical issues to undergo anesthesia and standard mid-urethral sling surgery
  • Women who have had unsuccessful or incompletely successful sling surgery
  • Women who wish to avoid surgery for SUI
  • Women who have SUI and wish to have more children
  • Women with mild SUI
  • Women with SUI who are anti-coagulated with “blood thinners” and whose anti-coagulation status cannot safely be reversed

How effective are bulking agents?

Generally, bulking agents result in a 75% improved or cure rate, including about 30% who are cured and 25% who fail to improve.  It is important to understand that the effectiveness of urethral bulking agents is inferior to that of sling surgery, the duration is limited and multiple repeat injections may be required. Improvement rather than cure is the goal.

Can urethral bulking agents be used for men as well as women?

Yes, they have been used in men with SUI after prostatectomy, but the results are less favorable than the results in women.

Bottom Line: Injection of urethral bulking agents is a reasonable alternative to mid-urethral sling surgery in certain populations of women who either are not medically fit for sling surgery, have failed sling surgery, or wish to defer or avoid sling surgery.
