OBJECTIVES We performed a comparative study of laparoscopic radical nephrectomy (LRN) and open radical nephrectomy (ORN) for renal cell carcinoma, and a comparative study of transperitoneal (LRN-TP) versus retroperitoneal LRN (LRN-RP) for renal cell carcinoma. MATERIALS AND METHODS A total of 100 patients underwent radical nephrectomy for stage T1 and T2(More)
Calcium oxalate kidney stones contain low amounts of proteins, some of which have been implicated in progression or prevention of kidney stone formation. To gain insights into the pathophysiology of urolithiasis, we have characterized protein components of calcium oxalate kidney stones by proteomic approaches. Proteins extracted from kidney stones showed(More)
PURPOSE Urinary macromolecules in children show stronger inhibition of Ca oxalate crystal growth, aggregation and adhesion than in adults. To investigate the mechanism of Ca oxalate urolithiasis we evaluated the differences in inhibitory activity against oxalate induced renal cell injury between adults and children. MATERIALS AND METHODS Urine samples(More)
PURPOSE The interactions between crystals and renal tubular cells are important factors in urolithiasis formation. Moreover, some reports have suggested the involvement of renal tubular cell injury in crystal-cell interaction processes. Atorvastatin, which is a competitive inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A, is prescribed to decrease high(More)
A 62-year-old diabetic woman with right hydronephrosis was referred to our department, presenting right back pain and high fever. A ureteral stone with right hydronephrosis was pointed on DIP. Although the calculus was removed by extracorporeal shock wave lithotripsy, persistent high fever continued. Abdominal computed tomography (CT) and magnetic resonance(More)
A 72-year-old woman consulted our hospital for a cystic mass in the right kidney. Ultrasonography and drip infusion pyelography revealed a right renal cystic mass 10 cm in diameter and right hydronephrosis. Computed tomography (CT) and magnetic resonance imaging revealed a giant mass with partial calcification in the right renal hilus. The mass was(More)
We report a case of intrascrotal rhabdomyosarcoma in a 59-year-old-male. The patient with a mass in the right scrotum was at first diagnosed with epididymitis and treated with antibiotics. The mass however, grew gradually and right orchiectomy revealed intrascrotal alveolar rhabdomyosarcoma. Para-aortic lymph node metastasis was pointed out by abdominal(More)
A case of rupture of giant hydronephrosis due to blunt trauma is reported. A 49-year-old male was admitted to our hospital complaining of right flank pain and gross hematuria after falling from a roof. Radiological evaluation lead to the diagnosis of marked right hydronephrosis with severe parenchymal thinning secondary to ureteral stone, left staghorn(More)
A 63-year-old woman with a right renal tumor diagnosed by ultrasound, consulted our hospital in October 2008. The findings of her physical examination were unremarkable. The results of urinalysis and other routine blood tests were normal. The urinary cytology was negative for malignant cells. Dynamic computed tomography showed a right renal mass (diameter,(More)
A case of epidermoid cyst of the testis is presented. The patient was a 64-year-old man who complained of a painless mass in the left scrotum. Physical examination revealed a hen-egg sized enlargement of the left scrotal contents. The ultrasonographic appearance did not show a hyperechoic partition, which is called echogenic rim, a characteristic of this(More)
