Thigh adductor contraction occurred in 17 of 160 patients during transurethral resection of newly diagnosed bladder tumours. In 13 of the 17 patients contractions were abolished by changing the site of the inactive electrode from the buttocks to the thigh. The topographic relationship between the obturator nerve and the bladder wall studied radiographically and at autopsy showed that the distance between the bladder and the nerve considerably diminished with increasing bladder volume. Thus, when obturator nerve stimulation occurs during transurethral resection transposition of the inactive electrode from the buttocks to the thigh should be tried first to prevent further stimulation. Moreover, TUR at low bladder volume may reduce the frequency of obturator nerve stimulation.
在对新诊断的膀胱肿瘤进行经尿道切除术时，160例患者中有17例出现大腿内收肌收缩。在这17例患者中，有13例通过将非活性电极的位置从臀部改为大腿，收缩得以消除。通过影像学和尸检研究闭孔神经与膀胱壁之间的地形关系表明，随着膀胱体积的增加，膀胱与神经之间的距离显著减小。因此，当经尿道切除术期间发生闭孔神经刺激时，应首先尝试将非活性电极从臀部移至大腿，以防止进一步刺激。此外，在膀胱容量较低时进行经尿道切除术可能会降低闭孔神经刺激的频率。
