前立腺全摘除術後に大腿神経麻痺をきたした2症例

Abstract

症例は69歳と66歳で, 大腿神経麻痺の原因はいずれもリンパ節郭清時に術野を展開するために深くかけたリングリトラクターの側板底辺が大腰筋を圧迫したことであると考えられた.麻痺症状は2例とも術後約1ヵ月で消失した

We report two cases of femoral nerve palsy after radical prostatectomy due to compression ascribed to the use of a ring retractor. The first case is in a 69-year-old man who fell when getting out of bed on the first postoperative day. Physical examination revealed hypoesthesia around the patella and weakness of the quadriceps muscle. The second case is in a 66-year-old man who complained of numbness of the anteromedial aspects of the right thigh and inability to extend his right knee on the first postoperative day. Postoperative femoral nerve palsy is not a well-recognized complication in urology. The literature was reviewed and the management of postoperative femoral nerve palsy was discussed.
