Purpose: Because vesicourethral dysfunction in myelodysplasia patients is a major cause of upper urinary deterioration and urinary incontinence, urodynamic evaluation should be performed as early as possible. We attempted to establish the proper time when videourodynamic study should be performed and which patients require early interventional therapy. Materials and methods: Out of the 222 patients seen in the pediatric urology department, 22 patients underwent correction of myeloplasia defect from January 2001 to September 2004. Preoperatively, the patients were assessed with videourodynamic study, and the postoperative videourodynamic studies were repeated at 2 to 6 months intervals. Four urodynamic parameters (bladder volume, compliance, detrusor activity and detrusor sphincteric synergy) were identified, graded and then added to obtain the urodynamic score. Results: There was no statically significant difference in all urodynamic parameters between the preoperative and postoperative 2 month videourodynamic studies, but a statistically significant difference was noted in compliance between the preoperative and postoperative 6 month videourodynamic studies. The compliance was more decreased in the patients who had received surgical correction in their older age and high detrusor activity was observed for these patients on the preoperative videourodynamic study. Conclusions: Postoperative videourodynamic study and early treatment are recommended for the patients who are at high risk for upper urinary tract deterioration. However, for the low risk patients, postoperative 2 month videourodynamic study can prevent unnecessary treatment.
