[Radical transurethral resection of prostate for spinal cord bladder: its therapeutic effects and urodynamic...

89 spinal cord injury patients who had voiding disturbance and were refractory to conservative therapy, were treated by radical transurethral resection of prostate (radical TUR-P). We evaluated the therapeutic effects of this procedure using clinical, urographic and urodynamic studies. 80 of 89 cases attained satisfactory voiding parameters after radical TUR-P. Postoperative incontinence was not seen and in some cases incontinence was improved. The vesicoureteral reflux was abolished in 15 of 23 refluxing ureters and ameliorated in 3 ureters. Hydronephroureters were normalized in 9 of 10 cases. Urodynamically, vesical compliance was increased after radical TUR-P. Detrusor hyperreflexia was suppressed in 6 of 15 cases. Detrusor sphincter dyssynergia was abolished or suppressed in 25 of 31 dyssynergic patients. By referring to the neuroanatomy and physiology of the denervated urethra, why radical TUR-P works was ascribed to its possible "sympathectomy" effect.
