The objective of this prospective study is to evaluate the hemodynamic impact of cervical conization on uterine artery blood flow by focusing on the Resistance Index (RI) as a direct indicator of distal vascular resistance. The central hypothesis is predicated on the physiological principle that the surgical excision and subsequent sealing of terminal cervical branches during conization increases the distal vascular impedance (afterload) encountered by the main uterine artery. Uterine artery Doppler RI measurements are performed preoperatively and at one month postoperatively to assess these alterations.
