Purpose: We report on a case of extragonadal germ cell tumor of the prostate associated with Klinefelter's syndrome. Methods/Results: The patient was a 33-year-old man. A transrectal prostate biopsy suggested combined germ cell tumor (yolk sac tumor + teratoma). Because there was no tumor except from the prostate, we considered this case to be a primary extragonadal germ cell tumor of the prostate. The prostate tumor responded to systemic chemotherapy with cisplatin, vinblastine and bleomycin and elevated lactate dehydrogenase and afetoprotein levels normalized. In addition to chemotherapy, the patient also underwent radiation therapy. Conclusion:The patient has survived for approximately 4 years since the diagnosis.

This results suggested that the stone number, stone history and urological complication were highly related to ipsilateral stone recurrence after stone free status by ESWL. Extracorporeal shock was lithotripsy had probability of higher stone recurrence rate.

Background : To investigate retrospectively whether the eight-core biopsy method improves the prostate cancer detection rate when compared with the standard sextant biopsy method in patients with prostate specific antigen (PSA) levels of 4

A case of metastasis to the seminal vesicle of renal cell carcinoma is reported. A 60-year-old man was referred to our department for evaluation of intermittent hematospermia and asymptomatic macrohematuria for about 2 years. He had a left radical nephrectomy for localized renal cell carcinoma 5 years ago. Panendscopy showed a little bleeding of posterior urethra, but there were no abnormal images of upper urinary tracts. Two years later he had asymptomatic macrohematuria again and panendscopy showed swelling and bleeding of verumontanum. Transurethral resection of verumontanum revealed clear cell carcinoma histopathologically and CT revealed seminal vesicle or prostate tumor, then total cystectomy was performed. Pathological examination indicated metastasis to siminal vesicle of renal cell ccarcinoma. There has been no report of metastasis to seminal vesicle of renal cell carcinoma in literature. This is the first case in the world.

Shortening of LOS using established clinical pathways reduces health care costs. However, in Japan, the wide range of preliminary results suggests that it may be too early to introduce the DRG/PPS system for health care cost. Furthermore nationwide investigations are needed before the introduction of the DRG/PPS system into Japanese health care reimbursement system.

A right nephrectomy was performed on a 51 year-old female with a tumor surrounding the right kidney since the possibility of malignant lymphoma could not be excluded based on radiography or a needle biopsy. An immunohistological examination of the surgically-resected specimen confirmed a diagnosis of pseudolymphoma. A pseudolymphoma involving the urinary tract is rare, and this is only the second reported case of pseudolymphoma in the perirenal space.
