膀胱全摘除術早期合併症と腸腰筋量の関係

Abstract

Psoas muscle mass index (PMI) is related to sarcopenia. We examined whether PMI is associated with early complications after radical cystectomy. Seventy one male and 29 female patients who were 65 years old or older and who had undergone radical cystectomy at our hospital from April 2005 to March 2018 were retrospectively analyzed. Psoas muscle section area was measured manually on preoperative computed tomography (CT) scan and normalized by patient's height. Early postoperative complications of grade 3 or more occurred in 12 male (16.9%) and 5 female (17.2%) patients. PMI was lower in male patients who had early postoperative complications of grade 3 or more than in those without complications (5.61 vs 6.54 cm2 /m2, p=0. 08), although the difference was not statistically significant. There was suggested to be a relationship between early postoperative complications after radical cystectomy and preoperative PMI in elderly male patients.
