The clinical experience of 273 cases of renal calculi treated by partial nephrectomy during the period of 1965-1982 is reported and the clinical data analysed. The ratio of male to female was 4 : 1. The patients were predominately (85%) adolescents and adults. The most common symptoms were hematuria, lumbago and less often irritation of the urinary bladder. About 86.3% of the calculi were located in the inferior calyx of the pelvis and 98.2% of the patients with various kinds of calculi can be completely removed by resection of the lower pole of the kidney, or supplemented with small incisions in the parenehyma. Conservaton of the renal tissue as much as possible during the operation was emphasized. Generlly, it was enough to excise 1/5—1/6 of the kidney and then the cut surface of the kidney was closed by continuous suture with "ooo" catgut passing through the pelvis or calyx along the borderline of the cortex and medulla. The advantages of this procedure were good hemostasis and a simple technique with rarely complications and no deaths. The post-operative complications were hemorrhage (1.4%), urinary fistula (0.74%) , wound infection (3.3%) . The recurrence rate of calculi was 15.5% in this series of patients. The renal function inproved in various degrees after operation. The operative indications are given with our modified technique. We have proved in our practice that through this procedure one may remove all of the calculi, eliminate the factors of recurrences, conserve renal tissue to the utmost extent and improve renal function of the affected kidney. Therefore, this procedure is safe and efficient when the operative indications are followed strictly.
