RESULTS The instruments most frequently used were single-item VAS and Biberoglu and Behrman pain score , while multidimensional inventories were used in few studies .
The results of clinical studies in CPP are more frequently based on one-dimensional measurements .
RATIONALE Many types of  pain assessment are available to research ers carrying out clinical trials in chronic pelvic pain ( CPP ) , ranging from a single-item scale to multidimensional inventories .
AIM Our objective was to investigate which assessment s of pain are more commonly used in clinical trials on CPP .
The efficacy of intravesical bacillus Calmette-Guerin in the treatment of interstitial cystitis: long-term followup.
PURPOSE Interstitial cystitis is a severe debilitating bladder disease characterized by unrelenting pelvic pain and urinary frequency . A prospect i ve , double-blind , placebo controlled study of the use of intravesical bacillus Calmette-Guerin ( BCG ) in the treatment of interstitial cystitis was recently completed with a mean followup of 8 months . Results demonstrated a 60 % BCG response rate , compared to a 27 % placebo response rate . We now report the long-term followup results of those patients who received intravesical BCG .  MATERIAL S AND METHODS Subjects r and omized to receive BCG  were followed at routine intervals with question naires and voiding diaries identical to those in the blinded study . Adverse events were closely monitored in the treatment and followup phases of the study . Subject baseline values were compared to followup data . RESULTS Of the BCG responders mean followup was 27 months ( range 24 to 33 ) , and 8 of 9 ( 89 % ) continue to have an excellent response in all parameters measured . The global interstitial cystitis survey improved 70 % , daily voids decreased 31 % , nocturia improved 54 % , mean voided volume increased 61 % , pelvic pain decreased 81 % , vaginal pain decreased 71 % , urgency decreased 71 % and dysuria decreased 82 % . Overall well-being improved 54 % and the R and -36 quality of life survey overall improved 64 % . In 86 % of the patients ( 6 of 7 ) dyspareunia resolved . Of the initial BCG nonresponders there was no significant difference in interstitial cystitis symptomatology from baseline to last followup , suggesting that BCG does not worsen interstitial cystitis symptoms . No long-term adverse events from BCG were noted . CONCLUSIONS Intravesical Tice BCG is safe , effective and durable in the treatment of interstitial cystitis . Of those patients who received only 6 weekly treatments and responded favorably 89 % continue to have an excellent response with followup ranging from 24 to 33 months
