Aplasia segmentar de corpo uterino em cadela sem raça definida: relato de caso / Segmental aplasia of the uterine body in a mongrel bitch: a case report

Relata-se um caso de aplasia segmentar parcial de corpo uterino em uma cadela sexualmente madura, em anestro, sem raça definida, em bom estado clínico geral. À necropsia, não foram identificadas alterações dos demais órgãos genitais, à exceção do corpo uterino, que apresentava redução de espessura numa extensão de 2mm na parte mediocaudal, com ausência de lúmen nesse ponto, e hidrometra em sua porção cranial e cornos uterinos. A avaliação histológica evidenciou redução da espessura total do corpo uterino no seu terço mediocaudal, porém presentes perimétrio, miométrio e endométrio, mas ausência de lúmen, bem como redução da espessura total da parede uterina nos cornos, com redução do número de glândulas endometriais. Nos ovários, foram identificados folículos em vários estádios de desenvolvimento e corpos lúteos em regressão, indicando que a cadela estava em atividade cíclica normal.

A case of partial segmental aplasia of the uterine body in a sexually mature mongrel bitch in anestrous phase and normal clinical condition is reported. At necropsy, no changes in the genital organs were observed with the exception of the uterine body that had a segmental (2mm in length) decrease in diameter in its medial-caudal portion, with absence of lumen and hydrometra in the cranial portion of the uterine body and uterine horns. Histopathologic evaluation indicated reduction in thickness of the whole uterine body at the site of stenosis, with all layers preserved including perimetrium, myometrium, and endometrium, but with the absence of a lumen. The walls of the uterine horns were thin and there was a marked decrease in the number of endometrial glands. There were several follicles on different stages of development and corpora lutea in regression, indicating that the bitch had normal cyclic activity.

Clinical Applications of Hysteroscopic Surgery in Postmenopausal Women / 대한폐경학회지

OBJECTIVES: To evaluate the spectrum of hysteroscopic surgery to be extended. METHODS: Forty-three women who underwent hysteroscopic procedures with Urione(R) solution or normal saline as distension media between March 2001 and March 2009 were randomized. The clinical characteristics, laboratory data, and post-operative results were retrospectively analyzed. RESULTS: The following hysteroscopic procedures were performed: endometrial biopsy, 26; endometrial polypectomy, 8; myomectomy, 7; ablation for dysfunctional uterine bleeding and endometrial hyperplasia, 1; and excision of an endometrial mass, 1. The mean size of the myomas was 3.2 cm. The average duration of hospitalization was 2 days. The average change in hemoglobin was 1.1 g/dl. The mean operative time was 36 minutes. CONCLUSION: The indications for hysteroscopic procedures can be extended. Pure intramural myomas, submucosal myomas, endometrial polyps, adenomyosis, endometrial hyperplasia, hydrometra, and abnormal uterine bleeding can be treated via a hysteroscope. Intra-operative transabdominal ultrasonographic guidance can be helpful during hysteroscopic procedures, and reduces the complication and morbidity rates.
