Spinal Vascular malformations (SVMs) are complex neurosurgical lesions and account for 3%-4% of all intradural spinal cord mass lesions, which can influence the function of bladder. The investigators' goal is to compare the efficacy of three different management strategies (sacral neuromodulation, botulinum toxin, M receptor antagonist) in treating consistent OAB (Overactive Bladder) in patients with SVMs after surgery.
