Outflow obstruction at the level of the external sphincter in patients with neurogenic bladder dysfunction is common and transurethral sphincterotomy the treatment of choice. Based upon the anatomy of the striated muscle fibres forming the external sphincter and its blood supply, we find from our results on 35 patients, 17 of whom had a follow-up of more than three years, a transurethral sphincterotomy only in the 12 o'clock position as sufficient and preferable. The results indicate that this comparatively simple technique is effective in order to diminish outflow resistance at the level of the membranous urethra. Concerning fresh paraplegics with unbalanced reflex bladder, sphincterotomy is usually not performed earlier than one year after the injury.
神经源性膀胱功能障碍患者的外括约肌水平流出道梗阻很常见，经尿道括约肌切开术是首选治疗方法。根据构成外括约肌的横纹肌纤维的解剖结构及其血供，我们对35例患者的研究结果发现，其中17例随访超过三年，仅在12点位置进行经尿道括约肌切开术就足够且更可取。结果表明，这种相对简单的技术对于降低膜部尿道水平的流出道阻力是有效的。对于反射性膀胱失衡的新截瘫患者，括约肌切开术通常在受伤后一年以内不进行。
