    Abstract:
    OBJECTIVE: To analyze the association between the disease duration and bladder dysfunction in lumbar disk herniation patients. METHODS: The urodynamic parameters of 85 lumbar disk herniation patients with different disease duration, 26 with the duration < 1 year (Group A), 31 with the duration of 1 - 5 years (Group B), and 28 of the duration > 5 years (Group C), were retrospectively analyzed. RESULTS: The average post-voiding residual volume of Group A was 50 ml, significantly lower than those of Groups B and C (80 ml and 120 ml respectively, both P < 0.05) with significant difference between Groups B and C too (P < 0.05). The average maximum cystometric capacity of Group A was (375 +/- 147) ml, significantly higher than those of Groups B and C [(481 +/- 184) ml and (562 +/- 173) ml respectively, both P < 0.05] and there was significant difference between Groups B and C too (P < 0.05). The average volume at the first desire to void of Group A was (220 +/- 88) ml, significantly lower than those of Groups B and C [(247 +/- 132) ml and (356 +/- 199) ml respectively, both P < 0.05], however, there was no significant difference between Groups A and B (P > 0.05). There were no significant differences in the maximum flow rate, maximum detrusor pressure, and bladder compliance among the three groups (all P > 0.05). CONCLUSION: Prolonged disease duration of lumbar disk herniation worsens the bladder function.
