ABSTRACT
We report a case of renal oncocytoma in 46-year old woman and review the literature. She had been asymptomatic except a visible protruding mass on the left abdomen and she underwent successful transperitoneal nephrectomy. The kidney weighed 4,800 gm, presented a well capsulated round mass and homogenous tan-brown colored cut surface. Renal oncocytoma, a rare neoplasm thought to arise from proximal tubular epithelial cells, exhibits a benign clinical course. They tend to misdiagnosed as renal cell carcinoma preoperatively. Histopathological studies confirm the oncocytic feature of the tumor cells, it shows finely granular eosinophilic cytoplasm(oncocyte) light microscopically, and the cytoplasm is filled with innumerable mitochondria with a paucity of other organelles ultrastructurally.

From December 1986 to August 1988, three patients with early prostatic cancer diagnosed primarily by fine needle aspriation cytology and/or Tru-cut needle biopsy underwent potency preserving radical retropubic prostatectomy. Herin we report the results and associated problems. Most difficulty was the diagnosis of the early prostatic cancer. We used fine needle aspiration cytology to diagnose the prostatic cancer primarily. One case of class V on the preoperative cytologic examination has proved to be BPH with chronic prostatitis postoperatively. Another problem was possibility of major bleeding intraoperatively, and complications were uncommon and not serious.

On a standpoint of commonly available ESWL for the treatment of urinary stone, percutaneous stone extraction had the role of cooperation to it, and sometimes it could be the first procedure of choice. We have performed percutaneous extraction of the renal and upper ureteral stones in 35 renal unite. The overall success rate was 78.4%, average operation time was 81 minutes, mean fluoroscopic exposure time was 11 minutes, average postoperative hospital stay was 7 days. Causes of failure were as followings ; five inadequate calyceal puncture, one ureteral perforation, one impacted stone, and one downward stone migration. The complications were inappropriate position of the nephrostomy tube, prolonged hematuria through nephrostomy tube, and partial ureteral avulsion. They were not serious but resolved by conservative management.

Primary aldosteronism, characterized by hypertension, hypokalemia and hyperaldosteronemia caused by chronic overproduction of aldosterone independent of normal renin-angiotensin system, due to aldosteronoma, or to bilateral cortical nodular hyperplasia, or to adrenal carcinoma rarely. We report a case of left adrenal adenoma which was diagnosed by classic clinical symptoms, laboratory data, adrenal venography and abdominal computerized tomography. We performed left adrenalectomy with subcostal transperitoneal approach, and then blood pressure and laboratory data were normalized postoperatively.

We tried percutaneous extraction of upper ureteral stones in five patients via Wolf rigid ureteroscope with grasping forceps. The procedure was performed at two session. The nephrostomy tract dilation was carried out by combination of metal dilator and Amplatz teflon renal dilator under fluoroscopy. All the five cases of PCN were successful without any complication at first trial. The advantage of this technique is low postoperative morbidity, rapid convalescence, sooner return to work and cheap price. It seems that endourological treatment of mid ureteral stone as well and upper ureteral stone can be extracted through percutaneous nephrostomy tract.

Tuberculoma means a tumor-like mass resulting from enlargement of a caseous tubercle which microscopically shows infiltration of epithelioid cells, Langhans giant cells and lymphocytes. In a 57-year-old woman suffering from left renal tuberculosis, we incidentally found a large retroperitoneal tuberculoma (site: retrohepatic, above right adrenal gland, below diaphragm and outside Gerota`s fascia, size: 13X11x9cm). Generally, Mycobacteria tuberculosis invade the lung via airway, and subsequently, they can be disseminated to any organ or tissue. They are apt to establish disease in the organ or tissue of high oxygen tension level. We report a case of retroperitoneal tuberculoma with wonder that it could develop in the retroperitoneum of poor blood supply.
