title: Interstitial cystitis in persistent posthysterectomy chronic pelvic pain.
abstract: OBJECTIVE
  Hysterectomies may be performed unnecessarily in women with chronic pelvic pain if the diagnosis of interstitial cystitis is not considered. The objectives of this study were to investigate the prevalence of interstitial cystitis in patients with posthysterectomy chronic pelvic pain and to evaluate the efficacy of various therapies for interstitial cystitis.
  
  
  METHODS
  A study was performed of 111 patients with chronic pelvic pain whose pain persisted after hysterectomy. Patients were screened with the Pelvic Pain and Urgency/Frequency symptom scale, and underwent Potassium Sensitivity Testing. Patients were treated with dietary changes alone or in combination with cystoscopic hydrodistention or oral pentosan polysulfate, or both of these, for 3 to 6 months.
  
  
  RESULTS
  Of the 111 patients enrolled, 79% (n=88) were diagnosed with bladder dysfunction consistent with interstitial cystitis. For patients treated with dietary modification alone (n=33), the mean score on the Pelvic Pain and Urgency/Frequency questionnaire improved 15.4%, from 13.18 at baseline to 11.15 at follow-up. For patients treated with pentosan polysulfate or cystoscopic hydrodistention, or both, plus diet changes (n=78), Pelvic Pain and Urgency/Frequency scores improved 34.2%, from 15.01 to 9.87.
  
  
  CONCLUSIONS
  In this study, nonsurgical treatment for interstitial cystitis resulted in a marked improvement in symptoms that had not improved with surgery. Without determining the origin of bladder pain, gynecologists should not proceed to hysterectomy in patients with chronic pelvic pain.
