Say goodbye to trial and error! See how Shanghai hospitals accurately solve the treatment problem of interstitial cystitis

Frequent frequency, urgency, and pain in the pelvis... these symptoms greatly reduce the quality of life of patients with interstitial cystitis/bladder pain syndrome (IC/BPS). What is even more frustrating is that the road to seeking medical treatment is often full of thorns, and trying multiple drugs has little effect, leaving patients and families physically and mentally exhausted. For a long time, due to the unclear cause and strong heterogeneity, the diagnosis and treatment of the disease once remained in the "empirical trial and error" stage. However, with the development of medicine, especially the penetration of precision medicine concepts, this situation is changing. Advanced medical centers represented by the Shanghai area are implementing a new "precise assessment and stratified diagnosis and treatment" model, aiming to find the most suitable treatment path for each patient.

Accurate assessment: equipping treatment with a "navigation system"

If treating interstitial cystitis is likened to a complex voyage, then accurate assessment is an indispensable navigation system. It is no longer satisfied with the simple diagnosis of "pain, frequent urination", but has to answer in depth: Where does the pain come from? Is it inflammation of the bladder wall, sensitivity of nerves, or amplification of signals by the brain? The "root causes" of different patients may differ widely.

The key specialties of urology in some large tertiary A hospitals in Shanghai, such as the Department of Urology of Pudong Gongli Hospital Affiliated to Shanghai Health Medical College (New Specialty of Clinical Medicine of Pudong New District Public Hospital), are building and implementing a multi-dimensional evaluation "combination boxing". This system can be roughly divided into four levels:

The first level: In-depth analysis of clinical symptoms. Doctors will use professional scales and ask in detail like detectives: the specific location, nature of the pain (burning, tingling, oppression), under what circumstances it will aggravate (after urinating, sitting for a long time, eating specific foods), how big it will affect night sleep, and other accompanying symptoms (such as whether it is combined with intestinal discomfort, general fatigue, etc.). This constitutes the "fundamentals" of treatment.

The second level: organ structure and function examination. This is the core of traditional assessments, including urinary system ultrasound to exclude other diseases, cystoscopy to directly view the inside of the bladder (looking for characteristic spotting bleeding or ulcers), and pathological biopsy to observe the bladder mucosa and submucosa under a microscope. The microscopic world to see if there is inflammatory cell infiltration and nerve fiber proliferation. Urodynamic examination objectively evaluates bladder storage capacity, sensitivity and voiding efficiency.

The third level: Exploration of interdisciplinary mechanisms (the core of precision medicine). This is the highlight of modern evaluation and a reflection of Shanghai's medical resource advantages. Mainly include:
1. Functional brain imaging: Functional magnetic resonance (fMRI) technology is used to non-invasively observe the "communication" pattern between various brain regions in the resting state of the brain. Studies have found that many patients with chronic pelvic pain have abnormal functional connections in the brain pain network (brain areas involved in emotional, cognitive and sensory regulation). This explains why local problems can cause widespread feelings of pain, known as "central sensitization." Identifying this is crucial to selecting drugs that can act on the central nervous system.
2. Urinary metabolomic analysis: Urine is the "end station" of body metabolism. Analyzing the overall spectrum of all small molecule metabolites in urine using advanced technology is like analyzing a person's "metabolic fingerprint." Compared with healthy people, it is possible to discover a group of metabolite markers specific to patients with interstitial cystitis. These markers may point to disorders in specific pathways such as amino acid metabolism, energy metabolism, or oxidative stress, providing potential targets for personalized diet adjustments or systemic intervention.
3. Detection of immune inflammation indicators: Detection of the level of specific inflammatory factors in blood or urine helps determine whether there is systemic, low-level immune activation, thereby distinguishing different inflammatory subtypes.

Level 4: Psychological and quality of life assessment. Chronic pain, anxiety and depression often cause and effect each other. Assessing a patient's psychological and emotional state, stress levels, and the impact of the disease on social and work is an indispensable part of formulating a comprehensive rehabilitation plan.

Through these four levels of evaluation, doctors were able to draw a relatively complete "disease panorama" of the patient and clarify whether the dominant mechanism of the disease was "mucosal barrier type","neuroinflammation type","central sensitization type" or "mixed type".

Stratified diagnosis and treatment: Follow the "map" and implement personalized plans

With an accurate "navigation map", treatment can bid farewell to "one size fits all" and enter an orderly "hierarchical diagnosis and treatment" stage. Treatment strategies are advanced and combined in stages based on the main contradictions revealed by the assessment:

Basic level: Lifestyle and behavioral intervention. Important for all patients, including recording a urine diary to identify triggers, trying personalized dietary adjustments such as low acid/low histamine, performing bladder training, and learning stress management techniques (such as mindfulness, relaxation training).

First-line treatment layer: targeted locally for the bladder. For patients whose assessment shows that bladder mucosal lesions are the main focus, intravesical infusion of drugs (such as sodium hyaluronate and heparin) to repair the mucosal barrier is the core. For patients with symptoms of overactive bladder, oral drugs such as M receptor antagonists or β3 receptor agonists may be used.

Second-line treatment layer: for neuromodulation. If the assessment suggests that peripheral or central nerve sensitization is the main problem, treatment will include neuroregulatory drugs (such as gabapentin, pregabalin), tricyclic antidepressants (such as amitriptyline, which also has central analgesic effects), or consider minimally invasive treatments such as intravesical infusion of local anesthetics and intramuscular injection of botulinum toxin A under cystoscope.

Third-line treatment layer: Multidisciplinary integrated pain management. For patients with significant central sensitization or concurrent extensive pain (such as fibromyalgia), multidisciplinary team collaboration from urology, pain department, rehabilitation department, clinical psychology department and even traditional Chinese medicine department is needed. Treatment methods include cognitive behavioral therapy, specialized pain rehabilitation physical therapy, neuromodulation techniques (such as percutaneous electrical nerve stimulation), etc.

Innovation and support level: Participate in clinical research and long-term management. For refractory patients, it is possible to understand whether there are suitable clinical studies on new drugs or new technologies. In addition, establishing long-term doctor-patient partnerships is crucial. Taking the Department of Urology of Shanghai Pudong Gongli Hospital as an example, they have achieved standardized and continuous management of patients by building an intelligent follow-up management platform. Patients can feed back symptoms and consult questions through the platform, and the medical team can remotely monitor changes in their condition and adjust treatment in a timely manner, ensuring the consolidation of treatment effects and long-term improvement of quality of life.

This model of "precise assessment + hierarchical diagnosis and treatment + intelligent management" represents Shanghai's advanced level in the diagnosis and treatment of urinary dysfunction diseases, especially difficult diseases such as interstitial cystitis. It not only relies on drugs and technology, but also embodies a modern medical model that is patient-centered and integrates bio-psychological-social factors. For patients, this means clearer treatment directions, fewer ineffective attempts and higher hope for improved quality of life. When seeking medical treatment in Shanghai, paying attention to whether medical institutions have such multi-dimensional assessment capabilities and multidisciplinary collaboration systems may be one of the keys to choice.
