Abstract
Selecting an IUD that fits the uterine dimensions is believed to be a keystone in improving IUD performance. This study included 15 women admitted for hysterectomy with no gross pelvic pathology distorting the uterine cavity and no contraindication to hysterography. Before hysterectomy the uterine cavity dimensions were measured using the Wing Sound II device and hysterography. After hysterectomy, direct measurements of the same dimensions were performed. The correlation between the Wing Sound II device measurements and those obtained by the direct method was highly significant except for the fundal transverse dimension where the correlation was moderately significant. On the other hand, hysterography measurements had a moderately significant correlation with those obtained by the direct method, except for the fundal transverse dimensions and the total uterine length where the correlation was insignificant. The Wing Sound II device is a simple, safe and accurate tool for studying uterine geometry on an out-patient basis.
Résumé
On pense que le choix d'un DIU qui convienne aux dimensions de l'utérus est un élément clé permettant d'améliorer l'efficacité du dispositif. L'étude présentée ici porte sur 15 femmes hospitalisées pour hystérectomie, sans importante pathologie pelvienne déformant la cavité utérine et sans contre-indication à l'hystérographie. Avant l'hystérectomie, les dimensions de la cavité utérine ont été mesurées à l'aide d'un appareil Wing Sound II et par hystérographie. Des mesures directes de ces mêmes dimensions ont été prises après l'intervention. La corrélation existant entre les mesures prises avec l'appareil Wing Sound II et celles obtenues par la méthode directe s'est révélée hautement significative, sauf en ce qui concernait la dimension tranversale du fond, où la corrélation n'était que modérément significative. D'autre part, les mesures de l'hystérographie n'ont donné qu'une corrélation modérément significative avec celles obtenues par mensuration directe, sauf pour la dimension transversale du fond, où la corrélation était insignifiante. L'appareil Wing Sound II est un instrument simple, sûr et précis pour l'étude de la géométrie utérine chez des patientes en consultations externes.
Resumen
Se cree que la selección de un DIU que se adapte a las dimensiones del utero es la clave para mejorar su acción. Este estudio incluye 15 muheres internadas por histerectomías, carentes de mayor patología pelviana que pudiera distorsionar la cavidad uterina y, sin contraindicaciones para histerografía. Antes de la histerectomía se tomaron las dimensiones de la cavidad uterina usando la Wing Sound II e histerografía. Después de la histerectomía se tomaron medidas directas de la mismas dimensiones. La correlación entre las medidas con la Wing Sound II y las obtenidas por el método directo, fué altamente significativo con excepción de la dimension transversal del fondo, donde la correlación fué moderadamente significativa. Por otra parte, las medidas histerográfias tuvieron una correlación moderadamente significativa con las obtenidas por el método directo, con excepción de la dimensión transversal del fondo y la longitud uterina total donde la correlación fué no significativa. La Wing Sound es un instrumento sencillo, seguro y preciso para estudiar la geometría uterina en pacientes externas.
