An unusually high incidence of urinary incontinence following transurethral resection of the prostate has been reported in patients with myasthenia gravis who were operated on for prostatism. It has been documented that this may be due to the vulnerability of the external sphincter to the electrothermal changes during transurethral resection of the prostate. In the case we studied, neuropathic changes were observed in the external sphincter; thus transvesical prostatectomy was performed instead, and no compromise of continence occurred.
据报道，因前列腺增生而接受经尿道前列腺切除术的重症肌无力患者出现尿失禁的发生率异常高。有文献记载，这可能是由于经尿道前列腺切除术期间外括约肌易受电热变化的影响。在我们研究的病例中，在外括约肌观察到神经病变；因此改为行经膀胱前列腺切除术，且控尿功能未受影响。
