COMPARISON OF URODYNAMIC INVESTIGATIONS BEFORE AND AFTER POSTERIOR SAGITTAL ANORECTOPLASTY FOR ANORECTAL-MALFORMATIONS

Methods: The authors evaluated 21 patients (10 boys, 11 girls) who had anorectal malformations (ARM). Ten of them had infralevator (low-grou p I) and 11 of them had supralevator (high-group II) type ARM. All of the patients underwent urodynamic investigation before and after poste rior sagittal anorectoplasty (PSARP) operation, Results: Sacral and sp inal anomalies were found in 54% (6 of 11) patients who had supralevat or type ARM. None of the patients with infralevator type ARM had addit ional sacral or spinal anomalies. Before PSARP operation urodynamic in vestigations of all infralevator type ARM patients were within normal limits, whereas 82% (9 of 11) of patients with supralevator type ARM s howed neurovesical dysfunction (NVD), There was no significant differe nce between the preoperative and postoperative urodynamic findings, Th e possibility of additional sacral or spinal anomalies and NVD in supr alevator type ARM was high, After PSARP operation no additional lower urinary tract dysfunction was detected in the urodynamic evaluation of ARM patients.
