高齢者の上部尿路結石に対するESWLの臨床的検討

Abstract

1991年以降, 上部尿路結石に対し, ESWLで結石治療を行った70歳以上の高齢者の上部尿路結石患者61症例67結石に対するESWLの治療成績・合併症について臨床的に検討した.重篤な合併症も少なく, 若年者と同程度の治療効果が期待でき, 高齢者の尿路結石に対しても, ESWL治療を積極的に行うことは可能と思われた

This study was aimed to evaluate the usefulness and feasibility of extracorporeal shock wave lithotripsy (ESWL) performed in elderly patients. ESWL by Triptor X-1 was used to treat 530 patients with upper urinary tract stones from 1991 to 1998. Sixty one (11.5%) of them were aged 70 years and older. The results of ESWL treatment in this elderly group were compared retrospectively with those in 122 patients aged from 20 to 39 and 243 patients aged from 40 to 59. Although the elderly had a higher incidence of preoperative risk factors, the postoperative complication rates were similar among all groups. The stone-free rate and the success rate at one month in the elderly group were 67.2% and 92.5%, respectively, which were similar to those in the younger groups. These results suggested that ESWL offered a safe and effective means of treating upper urinary tract stones in elderly patients.
