This study was undertaken to examine diabetic vesicourethral dysfunction in association with nerve conduction velocity. Uroflowmetry, water cystometry, International Prostate Symptom Score (IPSS), and nerve conduction velocity were analyzed in 29 diabetic patients (21 men and eight women; a mean age, 58.0 years). Nerve conduction velocity was measured for sensory nerve conduction velocity (SCV) of the sural nerve and motor nerve conduction velocity (MCV) of the peroneal nerve. Normal voiding was defined as continuous flow at the normal flow rate and residual urine <50 mL. Results of uroflowmetry and cystometry were compared with those of nerve conduction velocity. Eleven of 29 patients (38%) had voiding dysfunction. A vesical denervation supersensitivity test was negative in all patients. The mean IPSS was not significant different between patients with or without voiding dysfunction. Incidence of bladder volume at first desire to void >300 mL and maximum bladder capacity >500 mL were significantly higher in patients with abnormal SCV than those with normal SCV ( P < 0.03 and 0.001, respectively). Eleven of 16 patients with abnormal MCV showed voiding dysfunction, whereas all patients with normal MCV showed normal voiding ( P < 0.001). These results suggest that lower urinary tract symptoms alone cannot predict diabetic vesicourethral dysfunction and that diabetic vesicourethral dysfunction is highly correlated with abnormal nerve conduction velocity.
