ABSTRACT
Eleven patients with uric acid nephrolithiasis(Five with uric acid stones alone and six with both uric acid and calcium stone) underwent long-term treatment(0.5 to 3.75 years, mean of 2.33 years) with potassium citrate(30 to 80 mEq/day. usually 60mEq/day). Urinary pH increased from low(5.0-6.0) to normal(6.5-7.0) during treatment. Urinary content of uric acid which was 584+/-150 mg, day. slightly increased to 595+/-163 mg/day following treatment. Serum content of uric acid which was 6.45+/-0.9 mg%, slightly decreased to 6.1+/-0.8 mg%. The protein matrix was round in all 11 cases. And 4 types of nucleus were found. which were ca. oxalate, ca. phosphate, dried blood and suture material During the period' (Jan. 1987-Mar. 1990) of preventive management(enough fluid intake. restiction of animal protein and Polycitra-K), no new stones were found.

Between 1980 and 1989, our experience of surgical management with 21 adrenal diseases was presented. There were 3 cases of Cushing's syndrome, 3 of primary aldosteronism, 6 of pheochromo cytoma, 5 of neuroblastoma, 2 of extraadrenal paraganglioma, 1 of adrenocortical carcinoma and 1 of adrenal cyst. The use of advanced radiographic and laboratory procedures resulted in the refinement of diagnosis and localization of tumors, enabling better surgical management of adrenal disorders. Among those, 19 cases underwent unilateral adrenalectomy and 2 cases of Cushing's disease underwent bilateral adrenalectomy. Surgical approaches to the adrenal gland were transperitoneal in 16 cases and extraperitoneal in 5 cases. Operative complications occurred in 11 cases. The incidence, however, of complications related to the operative approach was not significant except in 2 cases of postoperative ileus.

The development of balloon catheters and advances in percutaneous endourology have made transluminal dilatation a safe and effective procedure for the treatment of benign ureteral strictures. Herein we introduce a case of our successful experience of percutaneous antegrade balloon dilatation of the allograft ureteral stenosis.

The accepted treatment for significant obstruction of the ureteropelvic junction has in general been open operative surgery. However, attention has recently been drawn to the efficacy of percutaneous pyeloplasty. We experienced the twenty-eight patients of the UPJ obstruction during a 10-year period. Of these patients 20 have underwent open pyeloureteroplasty and 8 were performed percutaneous pyeloplasty. Among these 8 patients, 5 were undergone endopyelotomy only and 3 were dilated successfully by balloon dilation after endopyelotomy. The results led us to evaluate these modalities for treatment of UPJ obstruction and the initial results of percutaneous pyeloplasty were encouraging.

Fewer articles deal with unrelated malignancies in the same individual at different times. There are only a few reports of different histologic tumors of the urinary tract occurring simultaneously We are presenting 1 case of dissimilar malignancies of the urinary tract occurring simultaneously.

The etiology of renal cell carcinoma has not been clarified and the familial renal cell carcinoma accompanied with karyotypic abnormalities is very rarely reported in the world literatures. Recently the approaches to evaluate the etiology of renal cell carcinoma are now being tried but it's relationship with the chromosomal abnormalities has not yet been clearly identified. We report two cases of renal cell carcinoma occurred in sister and brother who were treated with radical nephrectomy. And also we studied the pedigree of the family and the karyotype of peripheral leukocytes from four siblings which shows normal chromosomal patterns

In the 1980s ultrasound and CT gradually replaced angiography as the primary diagnostic modalities for renal masses. From 1983 to 1988, a comparative diagnostic study was carried out on 24 patients with pathologically proven renal cell carcinoma which were staged by various methods. Staging was correct with computerized tomography in 75 per cent of the lesions (15 of 20), with ultrasound in 68.2 per cent (15 of 22) and angiography in 53.8 per cent (7 of 13). We conclude that at the present time CT is the optimal technique to stage renal cell carcinoma. Angiography should be used selected cases not adequately evaluated by CT or ultrasound.

The Mainz pouch offers a low pressure reservoir of adequate capacity, antirefluxing ureteral implantation and continent reservoir for bladder augmentation and continent diversion. Reconstruction of a urinary reservoir using a Mainz pouch was performed on 2 patients in 1987. The Mainz pouch was used for bladder augmentation in one patient and for continent urinary diversion in other one. The operative technique and clinical results are described.

Malignant fibrous histiocytoma, which is interesting because of its pleomorphic nature, is a rare soft tissue sarcoma possibly arising from histiocyte. The tumors are usually situated in the skin or subcutaneous tissues, especially of the extremities, but they may also involve deeper structures, such as the retroperitoneum or genital organs. Herin we report a case of malignant fibrous histiocytoma in the retroperitoneal space and discuss the pathologic and clinical features.
