[Interstitial cystitis/bladder pain syndrome (IC/BPS)]

In this review, aspects of interstitial cystitis/bladder pain syndrome (IC/BPS) are presented against the background of the German S2k guideline on this disease.

Quite often this disease, characterized by bladder or lower abdominal pain (permanent or intermittent) and pollakisuria without pathogenic bacteria in the urine culture, is diagnosed much too late.

The debate on disease definition, aspects on pathophysiology and epidemiology are presented. For diagnosis, disease severity must be determined and relevant differential diagnoses like bladder cancer must be excluded. Conservative measures (clothing, food, sexuality, sport, bladder training, sufficient fluid intake, prevention of hypothermia) are effective especially in early stages of the disease. Combination drug therapy with mucosa stabilizing, anti-inflammatory, psychotropic, and pain-reducing drugs should be adjusted individually. Inpatient rehabilitation, hydrodistension, laser- and electrocoagulation, neuromodulation (sacral or pudendal) or hyperbaric oxygen therapy may help after pharmacotherapy failure. Cystectomy and urinary diversion are used in irreversible shrunken urinary bladder.

If all treatment modalities are consequently used, many patients may reach a state that is more bearable.

With a high level of suffering in many patients with IC/BPS, all available treatment modalities should be known and used.
