排尿障礙治療中心 版權所有 Diagnosis of Cauda equina lesion History of surgical trauma Dysuria and straining to void after spine surgery Constipation is the rule Saddle anesthesia or paresthesia Lower extremity motor deficiency

排尿障礙治療中心 版權所有 Urodynamics of Cauda equina lesion Detrusor areflexia at initial stage, sphincter tone is fixed (normal or weak) Bladder sensation of filling is normal or vague Bladder neck may be closed or open Bladder compliance is normal initially Patients void by abdominal straining

排尿障礙治療中心 版權所有 Neuroanatomy of pelvic plexus

排尿障礙治療中心 版權所有 Neuroanatomy of pelvic plexus

排尿障礙治療中心 版權所有 Radical abdominal hystertectomy Damage of plexus when excision extend to level of cardinal ligament or a long cuff vaginal excision Ureter lies above plexus, avoid ureteral injury will prevent plexus injury Limited lymph node dissection in the side without cervical cancer reduces postoperative voiding problem

排尿障礙治療中心 版權所有 Rectal cancer surgery Pelvic plexuses are vulnerable to injury during radical rectal surgery Pelvic plexuses share the same fascial sheath with the lower rectum Pudendal nerve may be damaged concomitantly during abdominoperineal resection of rectum (APR)

排尿障礙治療中心 版權所有 Neuroanatomy of Pudendal nerves

排尿障礙治療中心 版權所有 Consequences of pelvic plexus injury Parasympathetic decentralization and leave the ganglia in the plexus or detrusor muscles Sympathetic denervation and loss of coordinated regulation with parasympathetic nerves Sensory afferent nerves injury and loss of awareness of bladder filling

排尿障礙治療中心 版權所有 Urodynamic changes after pelvic plexus injury Detrusor areflexia immediately after injury Bladder sensation becomes vague and through peritoneal layer sensation The bladder neck is loose and can be opened by increased intravesical pressure Urethral sphincter tone may not change

排尿障礙治療中心 版權所有 Urodynamic changes after radical hysterectomy Recovery of detrusor contractility is usually incomplete & takes 6-12 months Significant residual urine in the women with lower abdominal straining pressure Bladder neck incompetence and isolated sphincter obstruction Urethral sphincter EMG activity may synchronously increased at bladder filling
