Introduction: Involvement of spinal cord in spinal tuberculosis (TB) has been associated with bladder disturbances on which literature is scarce. The present study aimed at evaluating the urodynamic profile, its correlation with clinical and radiological features, and the prognosis with treatment in these patients. Materials and Methods: Thirty patients of spinal TB were prospectively evaluated clinically, radiologically, and urodynamically in this single center prospective study. All patients underwent urodynamic assessment at presentation; and those with bladder dysfunction on initial urodynamics were followed with sequential testing at 3, 6, and 12 months. Results: Patients were divided into two groups on the basis of the absence (Group 1, n = 14) or presence (Group 2, n = 16) of bladder dysfunction. The magnitude of deformity (P = 0.011), sensory deficit (P = 0.025), and tenderness (P = 0.030) at presentation was found to be significantly more in Group 2 and involvement of posterior elements, reduction in disc height, endplate erosion, and nerve root were significantly higher. The initial urodynamic assessment showed delayed sensations in 23.3% and early sensations in 13.3%, respectively; decreased bladder compliance in 3.33%; underactive detrusor in 16.6%, and overactive in 13.3% of cases. The sphincter was dyssynergic in 13.3% of cases. Statistically significant (P < 0.001) improvement in sensory parameters of bladder, detrusor contractility, and compliance with treatment was observed. Thirteen (81.3%) patients of Group 2 showed overall improvement on serial urodynamics after chemotherapy. Patients with bladder disturbances had poorer functional recovery at 6 and 12 months. Conclusion: Significant bladder comorbidity is associated with spinal TB and its presence can be recognized as a poor prognostic factor. Urological morbidity is strongly linked to the nerve root and posterior element involvement; reduction in disc height; and end plate erosion. Clinical/neurological improvement correlates with marked radiological and urological improvement.
