Two Cases of Aldosteronoma / 대한비뇨기과학회지

Primary aldosteronism, characterized by hypertension, hypokalemia, and hyperaldosteronemia resulting from chronic oversecretion of aldosterone independent of normal renin-angiotensin regulatory system, is due mostly to aldosteronoma or to bilateral cortical nodular hyperplasia. We report two cases of primary aldosteronism due to adrenal cortical adenoma, which were diagnosed by clinical data and abdominal computed tomographic scan. Clinical symptoms and laboratory data returned to normal after surgical adrenalectomy.

Spontaneous Regression of Multiple Pulmonary Metastases of Advanced Renal Cell Carcinoma: A Case Report / 대한비뇨기과학회지

During an analysis of 27 patients cases of advanced renal cell carcinoma, eleven of which patients had pulmonary metastases. The case of a 53 year old male who underwent spontaneous regression of his lung metastases was found. This patient underwent right radical nephrectomy leaving some gross disease in the right lobe of the liver. Postoperatively regression was noted within 4 weeks and substantial decrease in the size of the metastatic lesions was noted before velban and Depoprovera were instituted 6 weeks after surgery. Complete disappearance of multiple pulmonary metastases was noted on the chest PA 8 weeks after surgery. At the time of the last clinic visit one year postoperatively, the pulmonary metastatic lesions had regressed entirely on the chest PA, leaving only micronodular hilar and Lt. lower lobe lesions on the chest CAT scan.

Clinical Observation for the Methods of Operation on Renal Stone / 대한비뇨기과학회지

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.

Clinical Observation of Renal Adenocarcinoma / 대한비뇨기과학회지

The clinical observation was made on 34 cases of renal adenocarcinoma in Department of Urology, Yonsei University College of Medicine, during the period from 1970 to 1980 (June). 1) Male to female ratio was 1.8:1, and the age distribution showed that the high peak incidence were fifth decade or later. 2)Chief complaints of its patients were palpable mass(64.7%), hematuria(61.8%), and flank pain(35.3%). 3) Left to right ratio of renal adenocarcinoma was 1.6:1, and 57.1% of the cases were developed in the upper portion of kidney, 35.7% in the lower portion, and 7.2% in the middle portion. 4) The cell types of renal adenocarcinoma showed that 75% of all the cases were clear cell type, 20% in granular cell type, and 5% in spindle cell type. The mean weight of nephrectomized kidney with renal adenocarcinoma was 680 gram. 5) The clinical stage coincided with final stage in 73% of all cases, and the accuracy of clinical staging in stage I and stage III was lower. 6) In the stage VI cases of renal adenocarcinoma, 60% of these cases were metastased to lung at the diagnosed period, 50% to bone, 40% to liver and 20% to lymph nodes except the regional area of affected kidney.
