Interstitial Cystitis Specialists

The CIGC specialists diagnose and treat pain caused by interstitial cystitis.

Interstitial Cystitis Discomfort Treatment Options

Interstitial cystitis (IC), also known as painful bladder syndrome (PBS), is defined as chronic bladder pain without identifiable causes. It can coexist with other conditions, such as endometriosis, fibromyalgia, irritable bowel syndrome (IBS), and autoimmune disease1. IC can be present in up to 60 percent of patients with endometriosis and may cause increased levels of pain and discomfort in these patients2.

IC is up to 10 times more common in women than in men3. Many patients experience disruption of home and work life, and 50 percent are unable to work full time. It is sometimes difficult to make a diagnosis of IC because other conditions share similar symptoms, such as pelvic pain and pain with intercourse.

Interstitial Cystitis Causes

There is little known about the cause of IC/PBS. Most patients cannot identify the event that triggered this condition. Certain foods, such as caffeine, alcohol, citrus fruits, tomatoes, and spicy foods, may worsen the symptoms.

Some theories on the causes of IC:

  • Defective bladder tissue
  • Mast cells that release histamine and other chemicals that lead to IC
  • Something in urine that damages the bladder
  • Changes in nerves that cause bladder sensations
  • The immune system attacking the bladder

Interstitial Cystitis Symptoms

Symptoms of IC include persistent, unpleasant sensations in the bladder, including discomfort with bladder filling, bladder pressure, and bladder spasms. The severity of symptoms can range from mild pressure to severe, debilitating pain. Additional symptoms include urinary frequency, urgency, and frequent urination at night. Seventy-five percent of patients with IC experience pain with intercourse.

Additional symptoms include:

  • Menstrual cramps
  • Abdominal pressure and bloating
  • Dysmenorrhea
  • Chronic pelvic pain

Sexual concerns are common in women with IC. In one study, 90 percent of women with IC reported low sex drive, difficulty with arousal, bladder pain during sex, and urge to urinate during sex.

Risk Factors3

  • Gender
    • Women are more likely to be diagnosed than men
    • Men who are suspected to have interstitial cystitis most likely are experiencing prostatitis
  • Skin and hair color
    • Fair skin and red hair have been associated with a greater risk of interstitial cystitis
  • Age
    • Most people diagnosed are in their 30s or older
  • Having a chronic pain disorder such as IBS or fibromyalgia

Complications

Untreated interstitial cystitis can lead to the following complications:

  • Reduced bladder capacity due to a stiffened bladder
  • Lower quality of life due to frequent urination and pain
  • Sexual intimacy problems due to frequent urination and pain
  • Emotional stress
  • Depression

Interstitial Cystitis Diagnosis4

The goal of a diagnosis is to identify the characteristic features of IC and to exclude other conditions. Diagnosis involves a detailed history of symptoms and associated conditions, a physical exam, and urine testing. IC does not have any characteristic findings on imaging studies. Cystoscopy may sometimes be helpful to exclude other conditions and in patients who do not respond to initial therapy.

Diagnostic methods include:
  • Biopsy, where doctors may remove a sample of bladder and urethra tissue during cystoscopy for a microscope examination
  • Urine cytology, where a urine sample is collected to rule out cancer diagnosis
  • Potassium sensitivity test, where water and potassium chloride are placed in bladder, one at a time
    • If patient feels more pain or urgency from the insertion of potassium chloride, the doctor will diagnose IC
Cystoscopy

Under anesthesia, a camera is inserted into the bladder, and the bladder is distended with sterile water (hydrodistention). This procedure allows the doctor to examine the inside of the bladder and perform a biopsy, if necessary. Cystoscopy is often performed with laparoscopy in patients with pelvic pain.

Petechiae, or bleeding spots, often seen after water dissension of the bladder (hydrodistension). This finding is often suggestive of Interstitial Cystitis.​

Abnormal findings on cystoscopy are helpful to support the diagnosis of IC. These findings include reddened lesions (Hunner’s lesions) and small red spots on the lining of the bladder.

Interstitial Cystitis Treatments

IC is a chronic pain syndrome, and there is no treatment that is curative. Treatments that may improve symptoms include lifestyle changes, medications, or procedures. Initial treatment of IC includes dietary changes such as increasing fluid intake and reducing alcohol and caffeine consumption. A second approach will include physical therapy and medications including ibuprofen, pentosan polysulfate, or amitriptyline. Beyond those treatment options, different surgeries may be recommended, such as bladder distention, nerve stimulation, and urinary diversion. There is no consensus on appropriate treatment of IC because the cause of this condition is unknown, the symptoms vary across patients, and there is not enough scientific evidence on the safety and effectiveness of treatments. No treatment has consistently provided relief for all patients. The goal of IC management is to provide relief of symptoms in order to achieve an adequate quality of life.

Treatment Options

There are many treatment options for IC, but none are proven to be helpful in all patients. Therapies vary by the risk of adverse reactions and the invasiveness of the treatment. In general, the least invasive therapy is chosen as a first-line therapy. If the symptoms persist, this therapy is discontinued, and another therapy is started. If the symptoms are severe, it may be necessary to proceed rapidly to more aggressive therapies5.

First-Line of Therapy

Initial therapy for IC is focused on self-care and changes in lifestyle and behavior to control the symptoms.

  • Application of local heat or cold over the bladder or perineum
  • Avoiding irritant food or beverages, such as caffeine, alcohol, artificial sweeteners, and hot peppers
  • Fluid and voiding: Patients who experience worsening of symptoms with concentrated urine should increase fluid intake
    • Others experience pain with bladder filling and may find that fluid restriction provides some relief
Second-Line of Therapy

Second-line therapy for IC may be time-consuming and usually requires a referral to a specialist.

  • Physical therapy may be helpful for patients who experience pelvic floor muscle tenderness upon examination
    • Pelvic floor physical therapy includes treatment of the tender points; pelvic floor physical therapists in the US can be found through the American Physical Therapy Association
  • Oral medications
    • Elavil, or amitriptyline, can be used as an initial treatment
      • This drug is most effective at higher doses but may not be well-tolerated due to side effects
    • Elmiron is reasonable for patients for whom Elavil is not effective or causes bothersome side effects
      • Elmiron is the only drug that has been approved by the FDA for treatment of IC
  • Antihistamines
Third-Line of Therapy

Third-line therapy is performed in the operating room under sedation.

  • Bladder hydrodistention: Sterile water is used to distend the bladder
    • Some patients can experience temporary relief from their symptoms (for up to six months)
  • Dimethyl sulfoxide (DMSO) instillation: The bladder is filled with a special solution weekly for six weeks, then every two weeks for three to 12 months
Fourth-Line of Therapy

InterStim is an implantable device that transmits electrical pulses to the sacral nerve located in the lower back. This device has been approved by the FDA for the treatment of urinary urgency and frequency, but not for the treatment of IC.

Fifth-Line of Therapy

There is little evidence to suggest that this therapy is effective. This therapy should only be administered by experienced professionals.

  • Bladder Botox: This treatment may cause urinary retention
    • Unapproved by the FDA for treatment of IC; symptom relief lasts up to six months
  • Restasis: This is an oral medication
    • It has limited use due to potential adverse side effects such as kidney toxicity, elevated blood pressure, immunosuppression, hair growth, muscle pain, and others
Sixth-Line of Therapy

This is a surgical procedure and the treatment of last resort. It is reserved for patients whose symptoms significantly affect their quality of life, in whom all other therapies have failed, and for patients who are willing to accept the potential complications and lifestyle changes.

  • Urinary diversion: The bladder is removed, and the ureters are attached to a new urine reservoir that is created from a bowel segment
    • In order to empty the new bladder, the patient will have to insert a catheter through an opening in the abdominal wall every four to six hours. This procedure will reliably relieve symptoms of frequency, but pelvic pain may persist.

The CIGC Difference

Interstitial cystitis is a common cause of pelvic pain, and in many cases can co-exist with endometriosis in up to 60 – 80% of patients. Since it is often very difficult to isolate IC as a cause for pain, in most patients a pelvic pain work up includes a diagnostic laparoscopy to evaluate and treat endometriosis if present. At the same time, cystoscopy with hydrodistension can be performed to evaluate for IC.

IC is a difficult disease to treat in its moderate to severe forms. Diagnosing the condition is the first step. CIGC surgeons include the evaluation of this condition in the diagnosis of pelvic pain. In many cases, patients with severe Interstitial Cystitis will require the services of a urologist well versed in the treatment of this condition.
