Interstitial Cystitis
Interstitial cystitis (IC), also known as bladder pain syndrome, is a chronic condition causing bladder pressure, bladder pain, and sometimes pelvic pain. The pain ranges from mild discomfort to severe pain. The condition is part of a spectrum of diseases known as painful bladder syndrome. While there is no cure for interstitial cystitis, medications and other therapies may offer relief. Interstitial cystitis can significantly impact quality of life, causing sleep disturbances, reduced physical activity, and emotional distress. It affects women more often than men and can occur at any age, though it's most common in middle age.

What Causes It?
Defective bladder epithelium - A leaky or damaged protective lining (epithelium) of the bladder may allow toxic substances in urine to irritate the bladder wall.
Autoimmune reaction - The body's immune system may attack the bladder tissue, causing inflammation and pain.
Neurogenic inflammation - Activation of pain-sensing nerves in the bladder can lead to release of substances that promote inflammation.
Mast cell activation - These immune system cells release histamine and other chemicals that can cause bladder inflammation and pain.
Pelvic floor dysfunction - Abnormal function of the pelvic floor muscles can contribute to interstitial cystitis symptoms.
Genetic factors - A family history of interstitial cystitis suggests a genetic predisposition.
Prior bladder trauma - Previous injury to the bladder, such as from surgery or infection, may increase risk.
Spinal cord trauma - Injury to the spine may affect bladder function and contribute to symptoms.
Cross-sensitization with other pelvic organs - Conditions affecting nearby organs like the bowel or reproductive organs may trigger bladder symptoms.
Certain foods and beverages - Some individuals report symptom flares after consuming specific items like coffee, alcohol, citrus fruits, or spicy foods.
Signs & Symptoms
Chronic pelvic pain - Persistent discomfort in the pelvis, between the navel and thighs.
Bladder pain that worsens as the bladder fills and improves after urination.
Urinary frequency - Needing to urinate more often than normal, sometimes up to 60 times a day in severe cases.
Urinary urgency - A persistent, urgent need to urinate, even immediately after emptying the bladder.
Pain during sexual intercourse - Particularly in women, pain may occur during or after sexual activity.
Dysuria - Painful urination without evidence of infection.
Nocturia - Waking up multiple times at night to urinate.
Small bladder capacity - The bladder may hold less urine than normal.
Symptom flares - Episodes of increased symptoms triggered by menstruation, stress, exercise, sexual activity, or certain foods/beverages.
Pain that changes with bladder filling and emptying - Often worse when the bladder is full and temporarily relieved after urination.
Hunner's lesions - Distinctive areas of inflammation visible on the bladder wall in about 10% of patients.
How We Diagnose
Our specialists use advanced diagnostic methods to accurately identify and assess your condition
Medical History and Symptom Assessment
Your doctor will conduct a detailed interview about your symptoms, their duration, severity, and factors that worsen or improve them. They will also review your medical history, including previous urinary tract infections, pelvic surgeries, or other medical conditions.
Physical Examination
A careful abdominal and pelvic examination to assess for tenderness, abnormal masses, or other physical findings that might explain symptoms or suggest other conditions.
Urinalysis and Urine Culture
Tests to rule out urinary tract infection, which can cause similar symptoms but requires different treatment. Your urine will be examined for bacteria, blood, and other abnormalities.
Voiding Diary
Recording fluid intake, urination frequency, and voided volumes over several days to objectively document urinary patterns and symptom triggers.
Pelvic Pain and Urgency/Frequency (PUF) Questionnaire
A standardized questionnaire that helps assess the likelihood of interstitial cystitis based on symptom severity and impact on quality of life.
Cystoscopy with Hydrodistention
A procedure where a thin tube with a camera (cystoscope) is inserted into the bladder, which is then filled with fluid to stretch it. This allows visualization of the bladder lining to look for Hunner's lesions, glomerulations (tiny hemorrhages), and to measure bladder capacity under anesthesia.
Potassium Sensitivity Test
A test where potassium solution is instilled into the bladder to test for increased sensitivity, which may indicate a defective bladder epithelium. This test is less commonly used now due to discomfort and limited diagnostic value.
Bladder Biopsy
Taking a small sample of bladder tissue during cystoscopy to examine under a microscope, which can help rule out other conditions like bladder cancer or identify specific features of interstitial cystitis.
Treatment Options
Personalized treatment plans tailored to your specific needs and condition
Oral Medications
Several medications may help relieve symptoms, including pentosan polysulfate sodium (Elmiron) which may restore the bladder lining, tricyclic antidepressants to help relax the bladder and decrease pain perception, antihistamines to reduce mast cell activity, and pain medications for symptom management. Elmiron is the only FDA-approved oral medication specifically for interstitial cystitis, though it may take 3-6 months to notice improvement.
Bladder Instillations
Medications can be directly instilled into the bladder through a catheter. Options include dimethyl sulfoxide (DMSO) to reduce inflammation, heparin to restore the bladder lining, lidocaine for pain relief, or combination "cocktails" of several medications. These treatments are typically performed weekly for 6-8 weeks, then as needed for maintenance.
Physical Therapy
Specialized pelvic floor physical therapy can help relax tight pelvic floor muscles, improve blood flow, and reduce pain. Techniques may include manual therapy, biofeedback, electrical stimulation, and exercises to strengthen or relax specific muscle groups.
Neuromodulation
Procedures that modify nerve activity to improve bladder function and reduce pain. Options include percutaneous tibial nerve stimulation (PTNS), sacral neuromodulation, or pudendal nerve stimulation. These treatments can help regulate bladder function and decrease pain signals.
Home Remedies
Dietary Modifications
Identifying and avoiding food triggers that worsen symptoms. Common irritants include caffeine, alcohol, artificial sweeteners, spicy foods, acidic foods, and carbonated beverages. An elimination diet followed by careful reintroduction can help identify personal triggers.
Heat or Cold Therapy
Applying a heating pad or ice pack to the lower abdomen or perineum may help relieve pain and discomfort. Warm baths (sitz baths) can also provide relief. Use for 10-15 minutes at a time, several times a day as needed.
Stress Management
Since stress can trigger or worsen symptoms, relaxation techniques such as deep breathing, meditation, yoga, or guided imagery may be beneficial. Regular practice of stress reduction activities can help manage flares.
Bladder Training
Gradually increasing the time between urinations to help increase bladder capacity and reduce frequency. Start by delaying urination for a few minutes when you feel the urge, and gradually increase the time interval as tolerated.
Pelvic Floor Relaxation
Learning to identify and relax the pelvic floor muscles can help reduce pain. Simple exercises include deep breathing while visualizing the pelvic floor dropping and releasing tension. A physical therapist can teach proper techniques.
Prevention Tips
Stay well hydrated with water, but avoid potential bladder irritants like caffeine and alcohol.
Practice timed voiding - urinating at regular intervals before the bladder becomes too full.
Wear loose-fitting clothing to reduce pressure on the bladder and pelvic region.
Develop healthy coping strategies for stress, as emotional stress can trigger symptom flares.
Maintain a food diary to identify and avoid personal dietary triggers.
Exercise regularly with low-impact activities like walking, swimming, or yoga to improve overall health without straining the pelvic floor.
Practice good bladder habits, such as emptying the bladder completely and urinating after sexual intercourse.
Use pelvic floor relaxation techniques regularly, especially during symptom flares.
Avoid holding urine for extended periods, which can increase bladder pressure and pain.
Maintain a healthy weight to reduce pressure on the bladder and pelvic floor.
Surgical Solutions
Advanced surgical procedures performed by our expert specialists
Cystoscopy with Hydrodistention
A procedure performed under anesthesia where the bladder is stretched with fluid. While primarily diagnostic, it can also provide temporary symptom relief in some patients by increasing bladder capacity and disrupting pain signals.
Hunner's Lesion Treatment
If Hunner's lesions are present, they can be treated during cystoscopy using laser, electrocautery, or resection to remove or destroy the inflamed tissue, which often provides significant symptom relief.
Botulinum Toxin (Botox) Injections
Injections into the bladder wall to temporarily paralyze bladder muscles, which may reduce pain and urgency. The effects typically last 3-6 months, after which the procedure can be repeated.
Cyclosporine A Implantation
In severe cases unresponsive to other treatments, surgical implantation of a cyclosporine A delivery system may be considered to provide continuous anti-inflammatory medication to the bladder.
Urinary Diversion
For the most severe cases that haven't responded to any other treatments, surgery to divert urine away from the bladder may be considered. This is a last resort due to the significant impact on quality of life and potential complications.
