Abstract

Aim

Tethered cord syndrome (TCS) manifests with neurological and urological complaints. Surgical detethering is the main treatment for TCS. Children with urological symptoms are required objective pre- and postoperative evaluations in order to predict urological outcome. The aims of this study are to investigate the effects of detethering procedure on the urodynamic tests and to determine the relationship between the changes of urodynamic tests and the patients’ age and gender.

Material and methods

The data of urodynamic tests in 46 pediatric patients, who underwent surgery for TCS, were retrospectively evaluated. Bladder capacity, post-voiding residual urine volume, maximum intravesical pressure, and bladder compliance of each patient were measured in preoperative period and at the third month after surgery. These parameters were statistically compared, and the correlations of these parameters with age, gender, and etiology of the TCS were also investigated.

Results

Bladder capacity and post-voiding residual urine volume were decreased and maximum intravesical pressure and bladder compliance were increased after surgery for TCS. The decrease in bladder capacity was significant in patients older than 10 years (p < 0.05). The increase in maximum intravesical pressure was also positively correlated with age (p < 0.05). But the increase in bladder compliance was negatively correlated with age (p < 0.05).

Conclusion

Bladder capacity, post-voiding residual urine volume, and bladder compliance are mainly affected by surgery in patients with TCS. From the urological viewpoint, children older than 10 years are most likely to benefit from surgery for TCS.
