BACKGROUND: Urinary catheter placement is essential before laparoscopic anterior resection for rectal cancer. Whether early removal of the catheter increases the incidence of urinary retention and urinary tract infection (UTI) is not clear. This study aims to determine the optimal time for removal of the urinary catheter after laparoscopic anterior resection of the rectum. METHODS/DESIGN: A total of 220 participants meeting the inclusion criteria will be randomly assigned to an experimental group or a control group...

Diagnostic methods currently used for bladder cancer are cystoscopy and urine cytology. Cystoscopy is an invasive tool and has low sensitivity for carcinoma in situ. Urine cytology is non-invasive, is a low-cost method, and has a high specificity but low sensitivity for low-grade urothelial tumors. Despite the search for urinary biomarkers for the early and non-invasive detection of bladder cancer, no biomarkers are used at the present in daily clinical practice. Extracellular vesicles (EVs) have been recently studied as a promising source of biomarkers because of their role in intercellular communication and tumor progression...

Urinary bladder cancer (UBC) is characterized by frequent recurrence and metastasis despite the standard chemotherapy with gemcitabine and cisplatin combination. Histone modifiers are often dysregulated in cancer development, thus they can serve as an excellent drug targets for cancer therapy. Here, we investigated whether G9a, one of the histone H3 methyltransferases, was associated with UBC development. We first analyzed clinical data from public databases and found that G9a was significantly overexpressed in UBC patients...

Importance: Hypofractionated radiotherapy (HRT) would be more convenient for men with low-risk prostate cancer and cost less than conventional radiotherapy (CRT) as long as HRT is noninferior to CRT in terms of survival and quality of life (QOL) is not found to be worse. Objective: To assess differences in QOL between men with low-risk prostate cancer who are treated with HRT vs CRT. Design, Setting, and Participants: In this phase 3 randomized clinical trial, men with low-risk prostate cancer were enrolled from sites within the National Cancer Institute's National Clinical Trials Network in the United States, Canada, and Switzerland...

PURPOSE OF REVIEW: Our aim is to review recent investigations into the recurrence of urothelial carcinoma in the upper urinary tract following bladder cancer therapy focusing on surveillance and management. RECENT FINDINGS: After radical cystectomy, rates of recurrence in the upper tract are between 0.75 and 6.4%. The poor prognosis of upper tract urothelial carcinoma (UTUC) is in part attributable to delayed diagnosis. Guidelines recommend a gradual de-escalation of surveillance in disease-free patients with the potential for discontinuation beyond 5 years...

Mesenchymal stem cells (MSCs) hold great promise as therapeutic agents in regenerative medicine. They are also considered as a preferred cell source for urinary tract reconstruction. However, as MSCs exhibit affinity to tumor microenvironment, possible activation of tumor-initiating cells remains a major concern in the application of stem cell-based therapies for patients with a bladder cancer history. To analyze the influence of adipose-derived stem cells (ASCs) on bladder cancer cells with stem cell-like properties, we isolated CD133-positive bladder cancer cells and cultured them in conditioned medium from ASCs (ASC-CM)...

BACKGROUND: Although physical activity has been reported as a protective factor for kidney and bladder cancer in epidemiological studies, it is not clear. METHODS: In a population-based prospective study of 76,795 Japanese aged 45-74 years, participants were evaluated physical activity by self-administered questionnaire. Hazard ratios (HRs) and 95% confidence intervals (CIs) of the risk of urological cancer were calculated by the Cox proportional hazards models...

AIM: Radical treatment of prostate cancer (PCa) is often associated with the development of urinary incontinence (UI). The etiology of UI after prostatectomy is multifactorial and can be caused by both urethral sphincter deficiency and bladder dysfunction. To date, there are no comparative studies of the development of UI in patients after either organ-preserving treatment or radical prostatectomy (RP). Considering this fact, our aim was to carry out the comparative assessment of urodynamic changes in these categories of patients...

Female urethral diverticular cancer is a very rare entity with only around 100 cases reported so far in literature and accounts for <1% of all malignancies. In this article, we present a 47-year-old African American female with repeated hospital visits for urinary retention, hematuria, and urinary tract infections. Initial computed tomography imaging and cystoscopy was unremarkable except for a distended urinary bladder. Subsequent magnetic resonance imaging and corresponding cystoscopy eventually indicated the presence of a urethral diverticulum...

PURPOSE: Medicare claims provide a rich data source for large-scale quality assessment because data are available for all beneficiaries nationally. For cancer surgery, the absence of information regarding site of cancer and date of diagnosis on an administrative claim necessitates testing to ensure accurate quality assessment and public reporting. METHODS: Using the SEER Medicare-linked database as the gold standard, we developed and tested an approach to identify cancer-directed surgeries from Medicare fee-for-service claims alone...
