Laser prostatectomy has evolved as a less invasive method of relieving bladder outlet obstruction due to prostatic enlargement. The elimination of adenomatous tissue by laser induced coagulation necrosis theoretically avoids the sequelae of fluid absorption noted during traditional transurethral resection of the prostate. However, to our knowledge no accurate determination of fluid absorption during laser prostatectomy has been performed to date.
A technique previously described to determine the amount of irrigant absorbed during transurethral resection of the prostate measures breath ethanol levels using a standard alcohol breath analyzer during the procedure after a predetermined amount of ethanol is added to the irrigant fluid. This method was used in 4 men undergoing laser prostatectomy.
All 4 subjects had ethanol levels of 0 throughout the operation, indicating that little or no irrigant fluid was absorbed.
We demonstrated in a quantitative manner that fluid absorption during laser prostatectomy is almost nil and patients are, indeed, at no risk for the transurethral resection syndrome.
激光前列腺切除术已发展成为一种用于缓解因前列腺肿大导致的膀胱出口梗阻的侵入性较小的方法。理论上，通过激光诱导凝固性坏死消除腺瘤组织可避免传统经尿道前列腺切除术中出现的液体吸收后遗症。然而，据我们所知，迄今为止尚未对激光前列腺切除术中的液体吸收情况进行准确测定。
一种先前描述的用于确定经尿道前列腺切除术中冲洗液吸收量的技术，是在向冲洗液中加入预定剂量的乙醇后，在手术过程中使用标准酒精呼气分析仪测量呼出气体中的乙醇水平。该方法用于4例接受激光前列腺切除术的男性患者。
所有4名受试者在整个手术过程中的乙醇水平均为0，表明几乎没有或没有冲洗液被吸收。
我们以定量方式证明，激光前列腺切除术中的液体吸收几乎为零，患者确实不存在经尿道切除综合征的风险。
