Methods: Patients with prostate cancer were eligible after screening of laboratory tests and pelvic contrast-enhanced computed tomography (CT). Pelvic region 18F-fluciclovine PET/CT was then acquired within 28 days and dissection of regional lymph nodes was performed within 60 days of pelvic contrast-enhanced CT.
Objectives: To examine the pre-emptive analgesic effect of the non-steroidal anti-inflammatory drug zaltoprofen against rigid cystoscopy-associated pain, and compare it with the effect of an anesthetic gel.
Methods: Forty men periodically undergoing follow-up office cystoscopy were enrolled in this prospective study. The effects of lidocaine gel alone or in combination with zaltoprofen, were examined.
Purpose: The aim of this study was to establish functional computed tomography (CT) imaging as a method for assessing tumor-induced angiogenesis.
Materials And Methods: Functional CT imaging was mathematically analyzed for 14 renal cell carcinomas by means of two-compartment modeling using a computer-discretization approach. The model incorporated diffusible kinetics of contrast medium including leakage from the capillary to the extravascular compartment and back-flux to the capillary compartment.
A 76-year-old man had transitional cell carcinoma of the bladder and underwent orthotopic ileal neobladder, and developed severe nocturnal enuresis. We performed videomanometry in the ileal neobladder and the rectum of the patient. Slow filling of the ileal neobladder showed overactivity (the amplitudes up to 50 cmH2O), which was similar to that normally seen in the rectum (the amplitudes up to 20 cmH2O).

Methods: Age, sex, stage, grade, histopathologic type, primary tumor size, site and number of metastatic organs, time to recurrence, IAP levels before nephrectomy and at the diagnosis of recurrence, and IAP doubling time just before recurrence were analyzed in 125 patients with recurrent renal cell carcinoma after nephrectomy.
Results: Univariate analysis identified stage, grade, histopathologic type, primary tumor size, time to recurrence, IAP level at the diagnosis of recurrence, and IAP doubling time as significant prognostic factors.
Objective: The purpose of this study was to clarify characteristics of baseline health-related quality of life (HRQOL) during the diagnostic process of prostate cancer.
Methods: A prospective study was conducted to measure HRQOL in a cohort of 141 patients in whom prostate cancer was suspected and prostate biopsy was scheduled, using both generic and disease-specific HRQOL measures (SF-36, UCLA-Prostate Cancer Index) at two points: before prostate biopsy (prediagnosis) and after giving biopsy results (postdiagnosis). Seventy-three patients were diagnosed with prostate cancer and 68 were not.
Aim: The clinical significance of the urinary white blood cell (U-WBC) count and serum C-reactive protein (CRP) level was evaluated in an effort to improve the efficiency of prostate biopsies.
Methods: We enrolled 228 consecutive patients with serum prostate-specific antigen (PSA) ranging from 3.0 to 20.
Aim: The objective of the present study was to clarify the indications, usefulness and limitations of ureterorenoscopy.
Material And Methods: From January 1998 to June 2004, 72 consecutive patients (48 men and 24 women) with a mean age of 66 years (range, 27-83 years) underwent ureterorenoscopy to diagnose upper urinary tract tumors (UUT). Median follow-up was 24 months (range, 1-73 months).
Aim: To investigate the prognostic and predictive relevance of p53 protein, Ki-67 antigen, MMP-2 and MMP-9 in patients with transitional cell carcinoma (TCC) of the upper urinary tract.
Methods: The expression of p53 protein, Ki-67 antigen, MMP-2 and MMP-9 was examined by immunohistochemistry in 69 patients with TCC of the upper urinary tract. Correlation of p53, Ki-67, MMP-2 and MMP-9 over-expression with conventional pathological parameters and patient survival was examined.
Objectives: The maximum size of adrenal tumors that should be removed by laparoscopic adrenalectomy is controversial. We conducted a retrospective comparison of the results of laparoscopic adrenalectomy between patients with adrenal tumors > or =6 cm ('large tumors') and patients with adrenal tumors <6 cm ('small tumors').
Methods: The participants in the study were 16 patients with large tumors and 111 patients with small tumors.
Purpose: Degradation of the extracellular matrix by malignant tumor cells has an essential role in the process of tumor invasion and metastasis. The 2 gelatinolytic matrix metalloproteinases (MMPs) MMP-2 and MMP-9 are believed to be key enzymes in this process. We investigated the possible relationship between in situ gelatinolytic activity of MMPs and clinicopathological factors in patients with bladder cancer to clarify whether these proteins would be critical for tumor advancement in this disease.

Although radical nephrectomy is a "standard" surgery for management of renal cell carcinoma, nephron-sparing surgery has become accepted for selected patients: those with solitary kidney, bilateral renal cell carcinoma or small renal cell carcinoma. Recently laparoscopic surgery has gradually come to include nephron-sparing surgery with minimum invasiveness. Furthermore, new methodologies such as cryoablation and radiowave ablation enable percutaneous management of nephron-sparing surgery.
