RESUMO
In our study we used transvaginal color Doppler ultrasonography in a token of 127 women presenting with unilateral ovarian tumor. The characteristics of the tumors were analyzed, the presence of vascularization was checked and the resistance index (RI) was calculated. Consequently, based on a concrete scoring system, we attempted to discriminate these tumors as benign or malignant. It was proven that 24 of 127 ovarian tumors were malignant. Transvaginal color Doppler correctly identified 21 of the 24 malignant tumors, as well as 94 of the 103 benign tumors. In nine other cases we had false-positive results. The sensitivity and the specificity of the method was 87.5% and 91.2%, while the positive and negative predictive values were 70% and 96.9%, respectively.

OBJECTIVE: To compare surgical outcomes of vaginal hysterectomy between women who have had one or more cesarean deliveries and those who have not. STUDY DESIGN: A retrospective, chart review study was performed on women undergoing vaginal hysterectomy during a four-year period. Of 275 women who met the study criteria, 104 had a history of previous cesarean deliveries, and 171 did not. The groups were compared for indications for surgery, operative time, length of hospitalization and surgical complications. RESULTS: Previous cesarean delivery did not affect hemoglobin loss, hospital stay or operative time among women undergoing vaginal hysterectomy. The complication rate (either operative or postoperative) was 12.3% among women without a history of cesarean section, 6.8% among those with one, 3.7% among those with two and 11.1% among those with three or more (chi 2 = 2.8, P = .4). The odds for surgical complications were not significantly different between women with one or more prior cesarean deliveries as compared to those without after adjustment for possible confounders. CONCLUSION: Surgical complications with vaginal hysterectomy do not appear to be higher among women with a prior cesarean section as compared to those without a history of such operation.
