Abstract

A clinical observation was made on 90 consecutive cases of urologic in-patients with renal stones in the Department of Urology, Yonsei University College of Medicine, from January, 1975 to December, 1979. 1) This disease occurred most frequently in the fourth decade, showing 29 cases of total urologic in-patients with renal stones and the ratio of male to female was 2:1. 2) 57 cases showed acidic urine, compared with alkaline urine in 25 cases. 3) Pyuria was observed in 57,3% and microscopic hematuria in 59.8%. 4) In 35.4%, cultures of urine were positive for bacteria and the common invaders were staphylococci and E. coli. 5) In 20.7%, of all cases there were urinary stones of other sites. 6) Pyelolithotomy in 47 cases (54.4%), nephrolithotomy in 16 cases (17.8%), partial nephrectomy in 7 cases (7.8%), nephrectomy in 12 cases (13.3%) and bivalve nephrolithotomy in 8 cases (8.9%) were performed. 7) In pyelolithotomy, single stone was 70.2%, and single stone and staghorn stone in nephrolithotomy were 43.8% respectively which were fixed to the renal calyx. In bivalve nephrolithotomy, staghorn stone was 75% and multiple stone in partial nephrectomy was 85.7% and staghorn stone in nephrectomy was 41.7%. 8) Transfusion was performed in bivalve nephrolithotomy, partial nephrectomy, nephrolithotomy, pyelolithotomy and nephrectomy in decreased order, operation times were longer in order of partial nephrectomy, bivalve nephrolithotomy, nephrolithotomy, nephrectomy and pyelolithotomy, and post-operative day was longer in partial nephrectomy with 11.3 days. 9) Postoperative complications were observed in 9 cases (10%). There were in differences in operative technique and secondary operation by postoperative complication was performed in 2 cases.
