Abstract

Thermotherapy of the uterus has emerged as an alternative to hysterectomy in the treatment of menorrhagia, from whence it follows that the thermal properties of uterine tissue have become of importance. This study presents measurements of the thermal conductivity and the water content of uterine tissue in vitro. A steady-state thermal conductivity apparatus, based on the comparison of test samples with n material with known thermal conductivity, is described. Measurements were conducted on tissue samples from eleven patients, directly after hysterectomy. Samples with and without endometrium, as well as coagulate samples, were examined. The thermal conductivity of myometrial tissue was found to be 0.536 ± 0.012 W m-1... (More)

Thermotherapy of the uterus has emerged as an alternative to hysterectomy in the treatment of menorrhagia, from whence it follows that the thermal properties of uterine tissue have become of importance. This study presents measurements of the thermal conductivity and the water content of uterine tissue in vitro. A steady-state thermal conductivity apparatus, based on the comparison of test samples with n material with known thermal conductivity, is described. Measurements were conducted on tissue samples from eleven patients, directly after hysterectomy. Samples with and without endometrium, as well as coagulate samples, were examined. The thermal conductivity of myometrial tissue was found to be 0.536 ± 0.012 W m-1 K- 1 (mean ± 1 SD) and the corresponding water content was 81.2 ± 1.5% (mean ± 1 SD). Measurements on samples with both endometrium and myometrium showed similar thermal conductivity (0.542 ± 0.008 W m-1 K-1, mean ± 1 SD) and water content (81.6 ± 0.7%, mean ± 1 SD). It was also indicated that coagulation causes dehydration, resulting in a lower thermal conductivity.
