泌尿器科単独標榜病院の20年の歩み : 原泌尿器科病院における手術統計(1971-1991年)

Abstract

The statistical analysis of the inpatients and operations in our department from April, 1971 to March, 1991 revealed a total of 9, 170 operations. One of the biggest changes in treatment is a marked increase in closed surgery. This includes endourological surgeries; transurethral resections of prostate and bladder tumor (TUR-P, TUR-Bt), percutaneous nephrolithotripsy (PNL), transurethral uretero-lithotripsy (TUL) and extracorporeal shock-wave lithotripsy (ESWL). From 1976 to 1980 there were 721 open surgical procedures (71.0% of cases) and 295 closed procedures (21.0% of cases). This ratio has now been reversed completely. From 1986-1991, there were 342 open procedures (8.2% of cases) and 3808 closed procedures (91.8% of cases). The main reason for this change was the introduction of the new techniques PNL, TUL and ESWL. Other important observations include: The incidence of emergency operations was higher in this private institution than that seen in non-private hospitals. From 1986, there was an increase in the use of PNL and TUL for the management of urinary calculi, and from 1988, ESWL has overtaken PNL and TUL in the treatment of this condition. Recently the limitations of ESWL have been appreciated and the value of a combined approach to therapy, for selected cases, is being recognized. A total of 238 ileal or ileocecal conduits were created with good results. A low complication rate has been observed with preservation of renal function.
