An unusual incidence of urinary incontinence was observed in patients with myasthenia gravis who required transurethral resection of the prostate for relief of obstruction secondary to benign prostatic hypertrophy. This urinary incontinence was not observed in patients who had open prostatectomies (suprapubic and retropubic). The urinary incontinence did not appear to be related to the control of the underlying muscular disorder. It is suggested that the external sphincter in patients with myasthenia gravis may be more vulnerable to thermal changes that occur when a blended current is used during transurethral resection. If prostatectomy is required in a patient with myasthenia gravis, open surgery should be the procedure of choice. If a TURP is used, then a high frequency current is advised with prudent resection in the area of the prostatic apex.
在患有重症肌无力且因良性前列腺增生导致梗阻而需要经尿道前列腺切除术以缓解症状的患者中，观察到了不寻常的尿失禁发生率。在接受开放性前列腺切除术（耻骨上和耻骨后）的患者中未观察到这种尿失禁。这种尿失禁似乎与潜在肌肉疾病的控制无关。有人提出，重症肌无力患者的外括约肌可能更容易受到经尿道切除术中使用混合电流时发生的热变化的影响。如果重症肌无力患者需要进行前列腺切除术，开放性手术应是首选方法。如果使用经尿道前列腺电切术（TURP），则建议使用高频电流，并在前列腺尖部区域谨慎切除。
