本研究乃是以一前瞻性的方法，去了解接受內視鏡時拎包括了經尿道攝護腺切除術及經皮腎臟截石術過程當中病人中心體溫的變化，及比較兩者的術後反應。研究進行中每個人的中心體溫是以食道溫度計測得。對於接受經尿道攝護腺除術或經皮腎截石術之病人而言，使用手術室室溫沖洗液者其平均體溫下降約2°C，而使用日溫過之沖液者，只下降約0.5°C。這種差異有統計學上的比較差異（P<0.05），而且對於實施經皮腎造截石術中以室溫沖洗液者，其溫度下降的程度和沖洗液使用量及手術時間長短有負相關性（P<0.05）。使用加溫沖洗液之病人在主觀的評估上其術後恢復也較佳（P<0.05）。本研究結果顯示：進行經尿道攝護腺切除或經皮腎臟截石術應該儘量保持病人體溫以減少溫度下降的程度及避免因低溫可能發生的併發症。

The aim of this prospective study is to characterize the decrease in core body temperature associated with transurethral resection of prostate (TURP) and percutaneous nephrolithotomy (PCNL), and to compare the patients response to room temperature irrigants and to warm irrigants perioperatively. Core body tern peratures were recorded during the periopertive period. Intraoperative temperature measurements were obtained via an esophageal thermistor probe. For patients undergoing either TURP or PCNL, the mean core temperature decrease 2.0°C room temperature in the patients with and a mean 0.5°C in those who with warm irrigants. Patients with room tempature irrigants significantly declined more core temperature intraoperatively. This decline was correlated with the amount of irrigants and the operation period in those undergoing PCNL with room temperature irrigants. (p<0.05) In addition, patients receiving warm irrigants recovered better subjectively. (p<0.05) The results suggested that efforts to preserve core body temperature during TURP or PCNL may reduce the degree of hypothermia and its potential complications.
