Objetivo: realizar um estudo comparativo entre os métodos utilizados para avaliar a cavidade uterina por meio da análise da sensibilidade e especificidade da histerografia e da histerossonografia, comparadas com a histeroscopia (padrão ouro). Métodos: foi realizado um estudo prospectivo para a investigação da cavidade uterina com a histerografia, a histerossonografia e a histeroscopia em 18 pacientes. Todas as pacientes apresentavam suspeita de anomalias da cavidade uterina. As principais indicações para a investigação foram: distúrbios do ciclo menstrual, sangramento pós-menopausa e alterações observadas em exames ultra-sonográficos sugestivas de pólipos, miomas e/ou espessamento endometrial. Resultados: a sensibilidade da histerossonografia foi de 90% e a especificidade 87,5%, quando comparadas à histeroscopia. O valor preditivo positivo foi de 90% e o negativo 87,5%. A histerografia, por sua vez, apresentou sensibilidade de 70%, especificidade de 75%, valor preditivo positivo de 77,7% e valor preditivo negativo de 75%. Conclusão: a histerossonografia parece ser um bom método alternativo para a avaliação da cavidade uterina, identificando algumas lesões não observadas à ultra-sonografia convencional ou à histerografia, e permitindo a triagem das pacientes candidatas à realização de uma histeroscopia diagnóstica ou cirúrgica. A histerografia apresentou resultados inferiores à histerossonografia, e não parece ser de utilidade na triagem das pacientes.

    ABSTRACT: To evaluate the accuracy and acceptability of hysterosonography (HS) in the diagnosis of uterine anomalies in patients with recurrent pregnancy loss. Sixty non-pregnant patients with a history of at least three previous recurrent miscarriages were submitted to the HS, HSG and hysteroscopy (HTC) exams. The findings fall into three categories: synechiae, polypoid lesions and abnormal uterine cavity shape. The HTC exam was used as the gold standard. The findings of the HS and the HSG were compared to the HTC's and the agreement was evaluated using the Kappa coefficient. Significance was established at < 0.05. Sensitivity, specificity, positive and negative predictive values were determined for each method. Uterine anomalies were present in 38.3% (23) of the patients: 16 (26.7%) with synechiae, 3 (5.0%) with polypoid lesions and 8 (13.3%) with abnormal uterine cavity shape. Accuracy of the HS and the HSG was 90.9 and 85.2%. General sensitivity of the HS was superior to the HSG (90.5 vs. 75.0%). It also had a higher degree of agreement with the HTC (Kappa = 0.81 vs. 0.68). The HS caused significantly less pain than the other two methods. The HS had higher diagnostic accuracy in the detection of uterine cavity anomalies and it was better tolerated by the patients when compared to hysterosalpingography and hysteroscopy.

    ABSTRACT: To evaluate and determine the main causes for pain occurrence and intensity in outpatients undergoing anesthesia-free hysteroscopy in a medical school hospital. Cohort study (Canadian Task Force classification II-2). Diagnosis Center of the Instituto Materno-Infantil de Pernambuco. One hundred seventy-one outpatients undergoing anesthesia-free diagnostic hysteroscopy. To assess pain occurrence, intensity, and associated factors reported by patients undergoing anesthesia-free diagnostic hysteroscopy. Pain frequency and intensity were determined by visual analog scale (VAS) at the end of the procedure and at 15-, 30-, and 60-minute intervals. Data analysis of clinical, obstetric, and gynecologic history and its association with pain was performed. Association through chi2 test (Pearson), risk ratio with 95% CI, and multiple logistic regression were used for statistical analysis. Pain score was higher immediately after the procedure with a median of 6, decreasing to 3, 1, and 0 at 15-, 30-, and 60-minute intervals, respectively. Multiple logistic regression was performed, and the only parameters remaining that were significantly associated with pain were menopause, speculum placement, and the absence of previous vaginal delivery. Anesthesia-free diagnostic hysteroscopy is often associated with pain, and it has been determined that menopause, speculum placement, and absence of previous vaginal delivery are factors associated with pain occurrence and intensity.
