Interstitial cystitis in Montreal: private treatments and care at the Sioufi Urology Clinic

Chronic pelvic pain. Constant urges to urinate, day and night. Burning sensations that don't correspond to any detectable infection. If you recognize yourself in these symptoms and antibiotics have never made a difference, you may be suffering from interstitial cystitis — a condition that is often misunderstood, frequently misdiagnosed, and yet very real.

At the Sioufi Urology Clinic in Montreal, we offer specialized and confidential care for women with interstitial cystitis , including intravesical dimethyl sulfoxide (DMSO) therapy , one of the most effective treatments available in Quebec in a private setting.

What is interstitial cystitis?

Interstitial cystitis (IC), also known as painful bladder syndrome (PBS), is a chronic inflammatory condition of the bladder wall. Unlike ordinary bacterial cystitis, it does not respond to antibiotics because it is not caused by an infection. Its exact origin remains partially understood, but involves damage to the protective lining of the bladder mucosa (glycosaminoglycans or GAGs), abnormal mast cell activation, and hypersensitivity of the bladder nerves.

Interstitial cystitis mainly affects women, often between the ages of 30 and 60. It can be mild and intermittent or, in severe cases, completely debilitating.

The most common symptoms include:

• Persistent pelvic pain or pressure, often aggravated by bladder filling

• Frequent and urgent need to urinate — up to 40 to 60 times a day in severe cases

• Burning sensation during urination in the absence of bacteria on culture

• Pain during sexual intercourse (dyspareunia)

• Partial relief after urination, followed by a rapid return of discomfort

These symptoms often fluctuate in cycles, with periods of remission and flare-ups aggravated by certain foods, stress, or hormonal changes.

A diagnostic process that is often long and exhausting

One of the most challenging aspects of interstitial cystitis is the diagnostic delay. On average, patients consult several doctors over 3 to 7 years before receiving a definitive diagnosis. Urine cultures come back negative, antibiotic treatments are repeated unnecessarily, and symptoms persist.

At Sioufi Urology Clinic, we conduct a rigorous and comprehensive evaluation to establish a reliable diagnosis: urinalysis, cystoscopy, intravesical potassium test if indicated, and exclusion of other differential diagnoses (infections, bladder stones, tumours). This structured diagnostic approach allows us to make the correct diagnosis quickly—and to begin treatment without further delay.

DMSO therapy: what is it and how does it work?

Dimethyl sulfoxide (DMSO) is an organosulfur compound approved by Health Canada for the intravesical treatment of interstitial cystitis. It is one of the best-documented and most widely used treatments in urology for this condition.

Mechanism of action

DMSO acts through several complementary mechanisms:

• Direct anti-inflammatory effect on the bladder wall

• Inhibition of mast cell activation, partly responsible for chronic pain

• Local analgesic effect — reduction of pain sensitivity in the bladder nerves

• Aid in the reconstitution of the protective GAG layer of the bladder mucosa

The instillation procedure

DMSO therapy is administered via intravesical instillations directly into the bladder through a small urinary catheter. The solution remains in the bladder for 15 to 20 minutes and is then eliminated naturally. The procedure is performed on an outpatient basis, without general anesthesia, and takes less than 30 minutes.

A standard protocol typically involves six weekly instillations, followed by monthly maintenance instillations as clinically indicated. Some patients combine DMSO with other intravesical agents (heparin, lidocaine, bicarbonate) to enhance the benefits—a personalized approach for each individual case.

What results can we expect?

Clinical studies on DMSO therapy for interstitial cystitis show encouraging results:

• Significant reduction in pelvic pain in 50 to 70% of treated patients

• Significant decrease in urinary frequency

• Improved quality of life, sleep, and ability to maintain daily activities

• Generally well tolerated — the main known side effect is a transient, characteristic garlic odor in the breath and perspiration, disappearing within 48 to 72 hours.

It is important to note that interstitial cystitis is a chronic condition requiring long-term management. The goal of treatment is not a complete cure, but a lasting reduction in symptoms, allowing for a normal and active life.

Other complementary therapeutic approaches

At the Sioufi Urology Clinic, interstitial cystitis is managed using a multimodal approach. In addition to DMSO, we can recommend or coordinate:

• Dietary changes — avoid acidifying foods (coffee, alcohol, citrus fruits, spices)

• Pelvic floor physiotherapy — to reduce associated muscle tension

• Oral medications — antihistamines, low-dose antidepressants, pentosan polysulfate sodium

• Stress management techniques — anxiety is a well-documented aggravating factor
