Two cases of adrenal pheochromocytoma associated with renal cell carcinoma are reported. The first case was in a 56-year-old woman who had been treated for hypertension. Computerized tomography (CT) scan revealed a right renal tumor and a right adrenal mass. ⋯ Right radical nephrectomy and left adrenalectomy were performed, followed by corticosteroid supplementation. In both cases, histopathological diagnosis was renal cell carcinoma and adrenal pheochromocytoma. Both patients had no clinical evidence for von Hippel-Lindau disease such as tumorous lesions of the central nervous system, spinal cord and retina, and cystic lesions of the kidney and pancreas.

Review Case Reports
[Renal cell carcinoma detected by metastasis to the frontal sinus: a case report].
A 58-year-old man was admitted with a swelling in the frontal region. Computerized tomography scan, magnetic resonance imaging and angiography revealed a tumor in the right frontal sinus. ⋯ Since there were no other systemic metastases, right nephrectomy was performed. Pathologically, the renal tumor was clear cell subtype renal cell carcinoma and had the same histology as the frontal sinus tumor.

Clinical symptoms, urodynamic findings, and urological treatment of 35 patients with neurogenic bladder dysfunction caused by Parkinson's disease (11 patients), multiple sclerosis (10 patients), and spinocerebellar degeneration (14 patients) were reviewed retrospectively. Most of the patients had a relatively low stage of disease, when they were first seen by their urologists. Chief urological complaints were of irritation in 63.6% of Parkinson's disease and 64.3% of spinocerebellar degeneration cases, compared with obstruction in 80.0% of multiple sclerosis cases. ⋯ However, none of them showed the clinical signs of primary disease progression. These findings indicate that in patients with Parkinson's disease, multiple sclerosis, and spinocerebellar degeneration, the urological symptoms can appear even in the early stage of disease. In addition, close follow-up is important in the urological management of neurogenic bladder patients with these diseases, because the disorders of the lower urinary tract may progress regardless of the status of the primary disease.

Review Case Reports
[Renal angiomyolipoma and renal cell carcinoma associated with tuberous sclerosis: a case report].
The relationship between tuberous sclerosis and renal angiomyolipoma of the kidney is widely recognized, but the association of bilateral renal angiomyolipoma with renal cell carcinoma in tuberous sclerosis is extremely rare. Our case seems to be the 5th case reported in Japan. We report here a case of bilateral angiomyolipoma and renal cell carcinoma of the right kidney with tuberous sclerosis.

A total of 61 patients with lower urinary tract injuries were treated at Nara Medical University and its affiliated hospitals, between January 1985 and June 1995. There were 9 patients with bladder injuries and 52 patients with urethral injuries. The main cause of bladder injury was a traffic accident sustained in 4 patients (44.5%) and that of urethral injury was an occupational accident sustained in 27 cases (51.9%). ⋯ Postoperative complications of urethral injury included urethral stricture in 30 patients (57.7%), incontinence in 3 (5.8%) and impotence in 3 (5.8%). A significant relationship between the duration of cystostomy and the incidence of postoperative urethral stricture was observed in our patients. Therefore at least three weeks of cystostomy will be necessary in the management of patients with complicated urethral injuries.
