负责这项研究的该医院泌尿科主任Peters接受美国媒体采访时表示，这一结果是“令人失望的”。

Peters said the major complication was leg weakness that developed among eight of the nine with spina bifida. All had been able to walk before the surgery. They often required intense physical therapy, Peters said, "just to get them back to baseline." One child developed drop foot, meaning he could not raise his foot when he walked.
"We knew there could be complications going in," he said, "but it was still frustrating."
