Laparoscopic transposition and reanastomosis of a circumcaval ureter were performed in a 52-year-old man with right flank pain. A preoperative perfusion pressure study revealed abnormally high intrapelvic pressure. Under laparoscopy, the renal pelvis was divided above the ureteropelvic junction and the ureter was relocated from behind the vena cava. A 5 cm(More)
OBJECTIVE CPT-11 is one of the most widely used camptothecin analogues and is converted to form the active metabolite SN-38. Clinical trials are ongoing to better characterize its spectra of clinical activity, to determine the optimal schedules of administration, and to define the usage in combination with other chemotherapeutic compounds. MATERIALS AND(More)
Gadolinium-labeled diethylenetriaminepentaacetic acid (Gd-DTPA)-enhanced magnetic resonance imaging (MRI) was evaluated in an effort to clarify whether MRI could replace or be proved to be superior to computerized tomography (CT) and/or transurethral ultrasonography. A total of 57 bladder cancer patients was evaluated. MRI was performed with a(More)
Transcatheter injection of ethanol into the renal artery was utilized in 11 patients with hypernephromas, clincally staged C or D, in an attempt to produce renal devitalization. Complete disappearance of the tumor neovascularity was achieved in 9 of 11 patients. Renal divitalization with ethanol injection is safer and more effective than the embolizing(More)
BACKGROUND It has been demonstrated that prostate cancer cells are relatively sensitive to heat stress. We have reported that heat treatment at 43 degrees C increases the expression of heat shock protein 70 (hsp70) in prostate cancer cells, leading to apoptosis. Hsp70 is a protein that protects cells against heat damage. Cells with lower levels of hsp70(More)
Renal cell carcinoma (RCC) is one of the most insensitive urologic tumors to either radiotherapy or anticancer chemotherapy. Recently, effectiveness of interferon (IFN) against RCC has been reported. However, because this effect is somewhat limited, a new modality of treatment is needed. We herein report our experience with IFN and OK-432, a streptococcal(More)
BACKGROUND Clinical differential diagnosis between malignant and benign tumors is important in order to select a therapeutic strategy for a primary retroperitoneal tumor. METHODS The clinical findings and radiological features of 25 patients with primary retroperitoneal tumors were retrospectively evaluated to find those signs that might contribute to the(More)
The signal transduction pathway showing how androgen withdrawal induces apoptosis in androgen-dependent cells has not been clearly understood. In these studies, we focused on the behavior of tyrosine kinases in androgen-dependent cells and investigated its correlation with apoptosis and bcl-2 expression. We used SC2G, an androgen-dependent mouse mammary(More)
A patient with renal cell carcinoma who developed humoral hypercalcemia of malignancy is reported. A 52-year-old male patient was diagnosed with renal cell carcinoma and multiple lung metastases. A cell line isolated from the surgical specimen exhibited continuous production of parathyroid hormone-related protein (PTHrP) in vitro. The production of PTHrP(More)
