Diversity in protein profiles of individual calcium oxalate kidney stones.

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 highly heterogeneous migration patterns in gel electrophoresis as reported.

[Endocervicosis/endosalpingiosis of the bladder: a case report].

Endocervicosis/ endosalpingiosis of the bladder is a very rare benign condition, with a total of 34 documented cases found in the literature. Herein, we report a 35-year-old woman with suspected bladder cancer following a cystoscopic examination, which revealed a mass on the right posterior bladder wall. Transurethral resection of the lesion was performed, and both pathological and immunohistochemical findings confirmed a diagnosis of endocervicosis/ endosalpingiosis.

[Epithelioid angiomyolipoma : a case report].

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.

[A case of urethrovaginal fistula caused by a foreign body in the vagina].

A 25-year-old woman had a urethrovaginal fistula caused by a foreign body in her vagina. The patient had sought an appointment with a gynecologist for removal of the foreign body in her vagina. However, one day before the scheduled appointment, she developed acute urinary retention and visited the emergency room of our hospital.

Effect of sex hormones on crystal formation in a stone-forming rat model.

Objectives: To evaluate the contribution of sex hormones in urolithiasis using a stone-forming rat model. Gender differences because of sex hormones are thought to influence the incidence of urolithiasis.

Methods: We divided rats into 7 groups, such as intact males, orchidectomized males, intact males subcutaneously implanted with testosterone, intact males subcutaneously implanted with estradiol, intact females, ovariectomized females, and intact females subcutaneously implanted with testosterone.

Mechanism underlying the low prevalence of pediatric calcium oxalate urolithiasis.

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 were collected from healthy men and their sons.

Clinical experience with laparoscopic radical nephrectomy for renal cell carcinoma.

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 disease. Of the 100 cases, 34 (34.

Atorvastatin inhibits renal crystal retention in a rat stone forming model.

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 cholesterol levels, and it has anti-inflammation and anti-oxidization activities.

[A case of giant renal artery aneurysm].

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.

[Traumatic rupture of giant hydronephrosis due to ureteral stone: a case report].

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 calculus and the rupture of right kidney.

[A case of intrascrotal rhabdomyosarcoma with para-aortic lymph node metastasis--complete response after multidrug chemotherapy].

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.

[Oral chemolysis of uric acid stones].

Oral chemolysis of uric acid stones was performed retrospectively. Twenty-one patients with upper urinary uric acid stones were given alkaline citrate (Uralyt-U) orally. In the case of hyperuicemia, allopirinol was combined.

[Epidermoid cyst of the testis difficult to make a preoperative diagnosis on the echoic examination: a case report].

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.

[A case of psoas abscess with ureteral stone].

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.

[Synchronous triple urogenital cancer (renal cancer, bladder cancer, prostatic cancer): a case report].

A case of synchronous triple urogenital cancer, which was comprised of renal cell carcinoma of the left kidney, transitional cell carcinoma of the urinary bladder, and adenocarcinoma of the prostate, is reported. A 72-year-old Japanese male patient was referred to our outpatient clinic with the complaint of asymptomatic hematuria. At that time, his serum of level of PSA was elevated to 20 ng/ml.

[A case of renal angiomyolipoma with marked cystic degeneration and pseudoaneurysm].

A 59-year-old woman consulted our hospital for a left renal mass which she had been aware of for 4 years. The tumor was in the lower portion of the left kidney. It was a cystic tumor whose wall was enhanced on computed tomography and magnetic resonance imaging.
