OP32.01: Ultrasonographical measurement of obstetric conjugate length

the patient with cervical carcinoma by using transvaginal ultrasound (TVUS). Methods: Based on the histological diagnosis of cervical cancer (biopsies and cone) and clinical stage of disease FIGO IB, 26 women have been included in the study. All patients underwent colour Doppler evaluation to assess intratumoral blood flow (colour scores), resistance index (RI), peak systolic velocity (PSV) and tumour size. Results: We were able to calculate the volume of tumour for all 26 patients and final results were: mean volume of tumour is 4.57 cm3, mean volume in pathologoanatomic specimen is 4.96 cm3. We found that TVUS measurement is more accurate in endophytic tumours with longest diameter under 2 cm, but there are problems with exophytic tumours. The mean difference in measurements were with tumours more than 3 cm and in exophytic ones. The ultrasound findings in exophytic tumours and those with the longest diameter more than 3 cm confirmed the presence of parametrial extension and node involvement. Conclusions: Our data suggest that TVUS measurement in estimation of the longest diameter and the volume of tumour with the help of colour Doppler examination in cervical carcinoma has to be considered a necessary procedure that give us information for stage of the disease in small tumours where a conservative management is an issue. However, TVUS has an important supportive aspect in women with cervical carcinoma stage IB willing to use ultrasound as assistance in the process of decision making.
