A 10-year clinical statistic survey was made on the operations performed at the department of urology, NTT West Osaka Hospital between 1992 and 2001. The total number of operations was 2,540, comprising 1,899 males and 641 females, and a total of 1,559 ESWL was performed. The number of operations per year was chronologically constant. Major operations were transurethral resection of prostate (299 cases). The number of operations for malignant tumors, for examples radical nephrectomy and enucleation for renal cancer, nephroureterectomy for upper urinary tract cancer and transurethral resection of bladder tumor, has increased since 1997 year after year. The number of ESWL has decreased since 1994. Renal transplantation was introduced in 1995, and laparoscopic adrenalectomy also in 1997.
