Interstitial Cystitis/Bladder Pain Syndrome Treatment Approach

Diagnosis and Treatment

The American Urological Association defines interstitial cystitis/bladder pain syndrome (IC/BPS) as unpleasant bladder-related sensation with lower urinary tract symptoms lasting more than six weeks, in the absence of infection or other identifiable causes 1.
The presence of Hunner lesions on cystoscopy fundamentally changes the treatment approach for IC/BPS 2, 3.
Basic assessment includes urinalysis and urine culture to exclude infection and other conditions 4.
Cystoscopy is not required for diagnosis in uncomplicated presentations, but should be performed when diagnosis is uncertain or when Hunner lesions are suspected 2, 4.

The American Urological Association recommends beginning with behavioral modifications and patient education before escalating to pharmacologic interventions 2, 4.
Dietary modifications, such as eliminating bladder irritants, may provide relief 2, 5, 6.
Fluid management and local temperature therapy may also be beneficial 2, 3, 6.
Pelvic floor muscle relaxation, rather than strengthening exercises, may help alleviate symptoms 1, 2, 6.
Oral medications, such as amitriptyline and pentosan polysulfate sodium, may be effective in managing symptoms 1, 3, 5, 6.
Intravesical treatments, including heparin and lidocaine instillations, may provide relief 1, 3, 5, 6.

Sacral neuromodulation and cyclosporine A oral therapy may be considered for refractory cases 1, 3, 5, 7.
Intradetrusor botulinum toxin A injections may be effective, but patients must accept the possibility of requiring intermittent self-catheterization post-treatment 5, 6, 7.
Major surgery, such as substitution cystoplasty or urinary diversion, should be reserved for carefully selected patients with severe, unremitting symptoms who have failed all other treatment options 3, 7.

Avoid pelvic floor strengthening exercises, as they may worsen symptoms 5, 6.
Educate patients that IC/BPS is a chronic condition with periods of flares and remissions requiring long-term management 3, 5.
Set realistic expectations, as treatment efficacy is unpredictable for any individual 5.
Discontinue ineffective treatments after an appropriate trial period rather than continuing indefinitely 3.
