다국어 초록 (Multilingual Abstract)

The surgical removal of dendritic calculi, isolated symptomatic caliceal calculi and large calculi from within the intrarenal pelvis has been always a difficuly problem and can be destructive to renal parenchyma. Following resulys are obtained through comparative investigation among extended pyelolithotomy, nephropyelolithotomy, anatrophic nephrolithotomy with hypothermia in situ and nephrectomy for snrgery of renal sones.
Among these methods, anatrophic nephrolithotomy with hypothermia in situ is performed in 16 cases who have renal stones which are considered to be difficult to remove by ordinary pyelolithotomy. This operative technique is relatively simple, easy and uneventful recovery followed in all cases.
The results are summarized as follows ;
1. Incidence of renal stones is 59 cases out of 840 total in-patients from January, 1978 to September, 1980.
2. The sex distribution is 32 patients are male and 27 patients are female.
3. The age distribution ranged from 7 years old to 72 years old, with the most common age group in the 31-50 years old.
4. Methods of operative mangement included ; extended pyelolithotomy in 27 cases, anatrophic nephrolithotomy with hypothermia in situ in 16 cases, nephropyelolithotomy in 2 cases and nephrectomy in 14 cases.
5. Blood loss during operation by anatrophic nephrolithotomy with hypothermia in situ, as compared with nephropyelolithotmy is reduced to a quaiter.
6. Operating time by anatrophic nephrolithotomy with hypothermia in situ required 95 minutes with mean operating time, extended pyelolithotomy-85 minutes with mean operating time, nephropyeslolithomy-120 minutes with mean operating time.
7. Postoperative hospitalizations are 9 days in anatrophic nephrolithotomy with hypothermia in situ, 8 days in extended pyelolithotomy, 15 days in nephropyelolithotomy and 8 days in nephrectomy.
