Sacral Chordoma and Rehabilitative Treatment of Urinary Disorders

Abstract

Sacral chordoma is one of the rarest tumors of the central nervous system (less than 1 % of the entire group). Mictional disorders are among the most frequent symptoms and are caused by the extrinsic compression brought to bear on the cauda equina and by surgical demolition of the sacrum. Seven patients who had undergone sacral resection for chordoma, starting from S₂, were followed for at least one year. It was observed that mictional disorders were often early symptoms signalling the presence of chordoma. Several patients were affected by a complete bladder denervation (infrasacral lesion) after surgery. Early rehabilitative treatment given after surgery for one year restored normal bladder functions in all the patients whose bladder denervation seemed to be not total (negative Lapides’ test). Even when a complete infrasacral lesion of the bladder has been ascertained, early rehabilitative treatment may well prevent serious renal damage.
