OBJECTIVE: Bladder cancer recurrence after management of upper tract urothelial carcinoma (UTUC) is a common disease. Although the incidence and risk factors for the development of noninvasive bladder tumor have been reported in many series, rare studies have reported on muscle invasive bladder cancer (MIBC) and its urethral recurrence. We aimed to report the incidence, risk factors and survival rate for the development of MIBC and urethral tumors after surgical management of UTUC. MATERIAL AND METHODS: We retrospectively reviewed patients who were surgically treated for UTUC from 1983 to 2013...

Epidemiological studies have suggested that prostatitis may increase the risk of prostate cancer due to chronic inflammation. We studied the association between several genitourinary infections and the risk of prostate cancer based on data from the EPICAP study. EPICAP is a population-based case-control study conducted in the département of Hérault, France, between 2012 and 2014. A total of 819 incident cases and 879 controls have been face to face interviewed using a standardized questionnaire gathering information on known or suspected risk factors of prostate cancer, and personal history of genitourinary infections: prostatitis, urethritis, orchi-epididymitis, and acute pyelonephritis...

Immune checkpoint inhibitors have not been effective for immunologically "cold" tumors, such as prostate cancer, which contain scarce tumor infiltrating lymphocytes. We hypothesized that select tissue-specific and immunostimulatory bacteria can potentiate these immunotherapies. Here we show that a patient-derived prostate-specific microbe, CP1, in combination with anti-PD-1 immunotherapy, increases survival and decreases tumor burden in orthotopic MYC- and PTEN-mutant prostate cancer models. CP1 administered intra-urethrally specifically homes to and colonizes tumors without causing any systemic toxicities...

The biology of masculinization is fundamentally important for understanding the embryonic developmental processes that are involved in the development of the male reproductive tract, external genitalia, and also the tumorigenesis of prostate cancer. The molecular mechanisms of masculinization are of interest to many researchers and clinicians involved in varied fields, including molecular developmental biology, cancer research, endocrinology, and urology. Androgen signalling is mediated by the nuclear androgen receptor, which has fundamental roles in masculinization during development...

BACKGROUND: Long noncoding RNAs (LncRNAs) represent a class of widespread and diverse endogenous RNAs that can posttranscriptionally regulate gene expression through the interaction with RNA-binding proteins and micro RNAs (miRNAs). Here, we report that in breast carcinoma cells, the insulin-like growth factor 2 messenger RNA binding protein (IMP1) binds to lncRNA urethral carcinoma-associated 1 (UCA1) and suppresses the UCA1-induced invasive phenotype. METHODS: RT-qPCR and RNA sequence assays were used to investigate the expression of UCA1 and miRNAs in breast cancer cells in response to IMP1 expression...

Madhumitha Reddy, Karim Kader
Bladder cancer is the sixth leading cancer in the United States. Radical cystectomy is a lifesaving procedure for bladder cancer with or without muscle invasion. Radical cystectomy is performed on 39% of these patients, and 35% will have a life-threatening recurrence. Distant metastases are the most common; local, upper tract, and urethral recurrence can also occur. Surveillance after cystectomy is critical to diagnosing recurrence early. Functional complications after urinary diversion include bowel dysfunction, vitamin B12 deficiency, acidosis, electrolyte abnormalities, osteopenia, nephrolithiasis, urinary tract infections, renal functional decline, and urinary obstruction, which can be reversed when diagnosed early...

REVIEW
Javier C Angulo, Reynaldo G Gómez, Dmitriy Nikolavsky
PURPOSE OF REVIEW: Due to the proximity of the rhabdosphincter and cavernous nerves to the membranous urethra, reconstruction of membranous urethral stricture implies a risk of urinary incontinence and erectile dysfunction. To avoid these complications, endoscopic management of membranous urethral strictures is traditionally favored, and bulboprostatic anastomosis is reserved as the main classical approach for open reconstruction of recalcitrant membranous urethral stricture. The preference for the anastomotic urethroplasty among reconstructive urologists is likely influenced by the familiarity and experience with trauma-related injuries...

Female urethral carcinoma is extremely rare and accounts for 0.02% of all women's cancers and <1% of cancers in the female genitourinary tract. Adenocarcinoma accounts for only 10% of urethral carcinomas in females. Due to their location, presentation is usually late and tumors are often missed on physical examination. As in this case, nonspecific symptoms in the early stages may delay the diagnosis in most patients. Herein, we present an extremely rare case of the columnar type of primary female urethral adenocarcinoma exhibiting colonic adenocarcinoma features which to the authors' best knowledge has not been reported to date...

PURPOSE OF REVIEW: Radical prostatectomy (RP) is the standard surgical treatment for localized prostate cancer. One of the side effects after RP impacting quality of life is urinary incontinence. Because of the impact in quality of life, more patients are seeking treatment for post-prostatectomy incontinence. Urodynamics are an important tool to help understand how prostate surgery changes bladder and urethral function. We reviewed the current literature in order to determine the role of urodynamics in post-prostatectomy incontinence...
