OBJECTIVE: To present bladder sensory data of three common peripheral nerve lesions (e.g., distal, intermediate/focal, and proximal).
METHODS: We measured first sensation (FS) and bladder capacity (BC) (not exceeding 600 ml) in 71 patients with peripheral nerve lesions: 35 diabetic neuropathy (D group), 6 post-pelvic surgery (S), and 27 cauda equina syndrome due to lumbar spondylosis (L). We excluded those with detrusor overactivity or low compliance that might affect bladder sensation.
RESULTS: The mean FS was 301.7 ml (D), 271.3 ml (S), and 189.4 ml (L), with the largest being in the D group (P < 0.05); the mean BC was 495.2, 475.4, and 391.4 ml, with the largest being in the D group (P < 0.05); who commonly had less frequent toileting. The mean post-void residual volume was 106.5, 29.0, and 42.0 ml; the values tended to increase along with BC. In the D group, the mean FS in patients with skin hypoalgesia as detected by pin prick and in those without it was 407.8 and 210.0 ml. The percentage of patients with FS < 100 ml was 5.7%, 0%, and 7.4%, respectively, who commonly had urinary urgency and frequency.
CONCLUSIONS: Bladder sensation is affected in diabetic neuropathy more severely than in intermediate/proximal lesions, together with somatic sensory disturbance. Bladder sensory disturbance leads to less frequent toileting, resulting in bladder over-distension and large post-void residuals. A small proportion of patients with peripheral nerve lesions develop urinary urgency, presumably reflecting irritation of the afferent nerve fibers or the urothelium.
