Two Cases of Inverted Papilloma of the Ureter / 대한비뇨기과학회지

Although inverted papillomas of urinary tract have been reported, the lesion of the ureter is rare and peculiar tumor characterized by unique microscopic finding. The prognosis of ureteral inverted papilloma is very favorable, only small number progress to higher grade tumor. We report 2 cases of ureteral inverted papilloma which were treated by segmental resection with end-to-end anastomosis of ureter.

Two Cases of Blind Ending Duplication of Ureter / 대한비뇨기과학회지

The blind ending duplication of ureter represents a rare anomaly in development of ureteric bud, and may almost be asymptomatic. We report two cases of blind ending duplication of ureter, that were detected incidentally.

Two cases of urethral polyp / 대한비뇨기과학회지

The urethral polyp is relatively unusual lesion but recently, has been reported more frequently Polyps of the anterior urethra are less common than those of the posterior urethra. The lesion is usually encountered in the young child but has occurred in the adult. Recently, we found two cases of urethral polyp. So, we report these with a brief review of the literature.

Primary Signet Ring Cell Adenocarcinoma of the Prostate / 대한비뇨기과학회지

A 61-year old man visited to our hospital due to gross hematuria and voiding difficulty. Microscopic examination of the prostatic tissue revealed a tumor composed predominantly of signet ring cells. Signet ring cell adenocarcinoma of the prostate is extremely rare disease. Recently we have experienced a case of signet ring cell adenocarcinoma of the prostate and report it with brief review of literature.

Management of Iatrogenic Ureteral Injury / 대한비뇨기과학회지

We treated 11 patients with iatrogenic ureteral injuries during a 4-year period: Gynecologic operations were the most common antecedent surgical procedures (82 percent). The diagnosis of ureteral injuries was made immediately in 4 patients and was delayed 3 to 56 days in 7. Three of the 4 injuries recognized during an operation were repaired successfully at the time of injury ; the primary repair in the remaining patient leaked and ultimately resulted in a nephrectomy because of subhepatic and retroperitoneal abscess formation. In the delayed diagnosis group, retrograde ureteral catheterization was successful in only 1 of all attempts. Of the 7 patients with injuries recognized in the postoperative period. 4 were managed successfully with ureteral stenting or percutaneous nephrostomy alone 3 required surgical after temporary percutaneous nephrostomy drainage.

A Case of Nonfunctioning Pheochromocytoma of the Bladder / 대한비뇨기과학회지

Pheochromocytoma originate from chromaffin cells and occur in the adrenal medulla in majority. About 10 per cent of pheochromocytomas can occur in the ectopic or extra-adrenal sites, anywhere along the fetal route of the chromaffin tissues. Pheochromocytoma of the bladder is a rare neoplasm that often occurs with the unique symptom complex of micturitional attacks, such as headache, palpitation, hypertension of sweating due to increased catecholamine secretion during detrusor activity. We report a very rare case of nonfunctioning pheochromocytoma of the bladder in a 67- year-old woman without typical symptoms. Preoperatively elevated urine catecholamines and their metabolites returned to normal after removal of the tumor.

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.
