Nerve damage can be caused by diabetes, alcoholism, and vitamin B12 deficiency. Peripheral nerves can also be damaged as a complication of major surgery of the pelvis, such as for removal of tumors. Diagnosis
The diagnosis of neurogenic bladder is made based on a complete history and physical examination and may require imaging and specialized studies. History should include information on the onset, duration, triggers, severity, other medical conditions and medications (including anticholinergics, calcium channel blockers, diuretics, sedatives, alpha-adrenergic agonist, alpha 1 antagonists). Urinary symptoms may include frequency, urgency, incontinence or recurrent urinary tract infections (UTIs). Questionnaires can be helpful in quantifying symptom burden. In children it is important to obtain a prenatal and developmental history.Ultrasound imaging can give information on the shape of the bladder, post-void residual volume, and evidence of kidney damage such as kidney size, thickness or ureteral dilation. Trabeculated bladder on ultrasound indicates high risk of developing urinary tract abnormalities such as hydronephrosis and stones. A voiding cystourethrography study uses contrast dye to obtain images of the bladder both when it is full and after urination which can show changes in bladder shape consistent with neurogenic bladder.Urodynamic studies are an important component of the evaluation for neurogenic bladder. Urodynamics refers to the measurement of the pressure-volume relationship in the bladder. The bladder usually stores urine at low pressure and urination can be completed without a dramatic pressure rise. Damage to the kidneys is probable if the pressure rises above 40 cm of water during filling.
