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 .
A randomized controlled trial of goserelin and medroxyprogesterone acetate in the treatment of pelvic congestion.
Following identification of the proportion of pelvic congestion among symptomatic patients complaining of chronic pelvic pain , and in a totally asymptomatic group of patients requesting tubal ligation , the efficiency of goserelin acetate versus medroxyprogesterone acetate was compared objective ly using pelvic venogram scores , and subjectively by symptom resolution , improvement of psychological status and sexual functioning in a prospect i ve r and omized trial in 47 patients with pure pelvic congestion syndrome . Patients received either goserelin acetate ( 3.6 mg/month for 6 months ) or medroxyprogesterone acetate ( MPA ; 30 mg/day for 6 months ) . Among patients with chronic pelvic pain , those with pure pelvic congestion were mostly parous , had the most severe pelvic signs and symptom scores , lowest rates of sexual functioning , and higher states of anxiety and depression as compared with others . At 1 year after treatment , goserelin remained superior to MPA in terms of pelvic venographic improvement as an objective measure . In alleviation of signs and symptomatology , improvement of sexual functioning and reduction of anxiety and depressive states as subjective measures , goserelin acetate achieved a statistically significant advantage ( P = 0.0001 ) compared with MPA
