三井記念病院泌尿器科における27年間(1970年6月～1996年12月)の手術統計

Abstract

1)悪性腫瘍の手術が増加しており, 特に腎細胞癌において著しかった. 2)尿路結石症において, ESWLの出現による手術件数及び術式の変化に対する影響は大きく, 前立腺肥大症において今日その殆どが内視鏡的治療によっていた. 3)小児泌尿器科手術が激減していた. 4)1980年以降の超音波断層法の発達, 普及が, 悪性腫瘍, 特に腎細胞癌の早期発見や尿路変更術, 腎生検術の術式の変化など, 泌尿器科領域の診断及び治療に与えた影響は大きいと考えられた

Statistical observations of the inpatient operations at our department during the 27-year period from 1970 to 1996 revealed the following: A total of 9, 287 operations were performed, comprising 7, 488 males and 1, 799 females. Operations for urolithiasis numbered 3, 646 (39.3%) which was the most frequent, followed by operations for urological malignancies, 2, 038 (21.9%) and for prostatic hyperplasia, 1, 596 (17.2%). In the last decade, the number of operations for malignancies, prostatic hyperplasia, and especially for urolithiasis has increased. However the number of operations on pediatric cases has shown a marked decrease. Thanks to the development of new diagnostic and therapeutic medical modalities, including ultrasound, computed tomographic scans, endoscope and extracorporeal shockwave lithotripsy, the frequency of early cancer has thus increased, and the surgical procedure of choice has dramatically shifted to minimally invasive surgery.
