OBJECTIVES To investigate the oncological and functional outcome of distal ureterectomy compared with nephroureterectomy in the management of distal ureteral urothelial carcinoma. METHODS Using a database including upper urinary tract urothelial carcinoma patients (n = 1329), 282 patients were identified with urothelial carcinoma localized in the distal(More)
PURPOSE We evaluated the usefulness of pre-biopsy multiparametric magnetic resonance imaging and clinical variables to decrease initial prostate biopsies. MATERIALS AND METHODS We prospectively evaluated 351 consecutive men with prostate specific antigen between 2.5 and 20 ng/ml, and/or digital rectal examination suspicious for clinically localized(More)
To assess whether there is an association between the apparent diffusion coefficient (ADC) value and the pathological characteristics of prostate cancer. The study cohort consisted of 29 consecutive patients with prostate cancer treated with radical prostatectomy. All patients underwent diffusion-weighted MRI before the prostate biopsy. In 42 tumor foci,(More)
PURPOSE We clarified the diagnostic ability of multiparametric magnetic resonance imaging to reveal anterior cancer missed by transrectal 12-core prostate biopsy based on the results of 3-dimensional 26-core prostate biopsy, which is a combination of transrectal 12-core and transperineal 14-core biopsies. MATERIALS AND METHODS The study population(More)
To reduce the incidence of inguinal hernia (IH) after radical retropubic prostatectomy (RRP), a simple prophylactic procedure was carried out during RRP. A consecutive 82 patients who had undergone RRP for clinically localized prostate cancer between July 2002 and October 2006 at Toride Kyodo General Hospital were enrolled. From July 2002 to November 2003,(More)
OBJECTIVES To determine the relationship between body mass index and prostate cancer risk at biopsy in Japanese men, and to compared the risk with that of Caucasian men. METHODS We retrospectively evaluated 3966 men with prostate-specific antigen levels from 2.5 to 19.9 ng/mL who underwent an initial extended prostate biopsy. Using logistic regression,(More)
An 86-year-old man with a serum prostate-specific antigen level of 93.33 ng/ml was diagnosed as having cT3aN0M0 prostatic adenocarcinoma of Gleason score 9. Although the serum prostate-specific antigen responded well to combined androgen blockade, the cancer spread and lead to death 6 months after diagnosis. The patient had leukocytosis during the clinical(More)
We report a case of clear cell adenocarcinoma of the urinary bladder. A 59-year-old male was referred to our hospital complaining of oliguria, left lower abdominal pain and loss of appetite. Ultrasonography revealed bilateral hydroureteronephrosis and obstructions at the ureterovesical junction. Magnetic resonance imaging demonstrated an invasive irregular(More)
As a result of the dramatic improvements in the resolution, wearability, and weight of head-mounted displays (HMDs), they have become increasingly applied in the medical field as personal imaging monitors. The combined use of a multiplexer with an HMD allows the wearer to simultaneously and seamlessly monitor multiple streams of imaging information through(More)
OBJECTIVE To investigate the expression profiles and protective roles of the inducible isoform of heme oxygenase-1 (HO-1) in cyclophosphamide (CYP)-induced cystitis, as the HO system is involved in heme degradation and plays an important role in cellular homeostasis but its characterization is still unknown in urinary tract diseases.
