膀胱内体温計の非観血的摘除術

REMOVAL OF A CLINICAL THERMOMETER IN THE URINARY BLADDER WITHOUT SURGERY

緒言

　膀胱異物としての体温計は破損のおそれがあるため経尿道的摘除が困難であり，多くは膀胱高位切開により摘除されている。

　私は体温計が水銀槽を下にして水中に直立することを利用し，イメージ直視下にきわめて簡単に摘除し得た1例を経験した。この経験から本邦報告例を集計するとともに，その非観血的摘除術について私見をのべたい。

Transurethral removal of a clinical thermometer as a foreign body in the bladder is difficult, because there is the risk of being broken. Mostly it is removed with suprapubic cystotomy. Based on the fact that a clinical thermometer takes an upright position with its mercury part down in water, the author removed the thermometer very easily in one 41-year-old female case by injecting solution enough to make the thermometer movable in the bladder and picking up the mercury part using Pean's forceps covered with Penrose drain under the direct vision of fluoroscopy. The length of the clinical thermo-meter was 11.3cm, which showed 38.0℃.
