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 .
Laparoscopic uterine nerve ablation versus vaginal uterosacral ligament resection in postmenopausal women with intractable midline chronic pelvic pain: a randomized study.
OBJECTIVE To assess and compare the laparoscopic uterine nerve ablation ( LUNA ) and the vaginal uterosacral ligament resection ( VUSR ) in postmenopausal women with chronic pelvic pain ( CPP ) . STUDY DESIGN Eighty postmenopausal women with intractable and severe midline CPP were r and omized to undergo LUNA or VUSR .  Costs of two surgical procedures were assesses . Cure rate , severity of CPP , and deep dyspareunia were also evaluated after 6 and 12 months from surgery . RESULTS The mean cost of LUNA  result ed significantly higher in comparison with VURS ( 2078+/-637 versus 1497+/-297 , P<0.001 ) . The cure rate was not significantly different between the two groups at 6 ( 33/40 , 82.5 % versus 35/40 , 87.5 % for groups A and B , respectively ; P=0.530 ; RR 0.94 , 95 % CI 0.78 - 1.13 ) , and 12 months ( 27/36 , 75.0 % versus 28/38 , 73.7 % , for groups A and B , respectively ; P=0.901 ; RR 0.90 , 95 % CI 0.78 - 1.33 ) of follow-up . At same times , a significant ( P<0.01 ) decrease in severity of CPP and deep dyspareunia was observed in both groups with no difference between them . CONCLUSIONS Both LUNA and VUSR are equally effective surgical treatments in postmenopausal women with central CPP but VUNR is significantly cheaper than LUNA
