OBJECTIVES: To study the behavior of specific coagulation factors in different types of non-metastatic urological cancers, and to identify their possible role as diagnostic and prognostic markers. METHODS: This was a prospective controlled study, which included three cancer patient groups and a control group of healthy individuals. The cancer subgroups consisted of renal (n = 44), prostate (n = 56) and bladder cancer (n = 47). We excluded patients receiving anticoagulant therapy, or with significant comorbidity...

PURPOSE: Frailty and functional status have emerged as significant predictors of morbidity and mortality for patients undergoing cancer surgery. To articulate their impact on value (i.e., quality per cost), we compared perioperative outcomes and expenditures according to patient function for older adults undergoing kidney cancer surgery. MATERIALS AND METHODS: Using linked SEER-Medicare data, we identified 19,129 elderly patients with kidney cancer treated with non-ablative surgery from 2000-2009...

INTRODUCTION: Rates of successful transition from adolescent to adult spina bifida (SB) care are unknown. OBJECTIVE: We aimed to assess rates and predictors of successful transition from a multidisciplinary SB clinic to a transitional urology clinic (TUC), or a pediatric or adult urologist. STUDY DESIGN: We retrospectively reviewed patients discharged from a multidisciplinary SB clinic (2006-2012), collecting demographic and clinical data...

Renal cell carcinoma is one of the most common urological tumors. The role of programmed cell death 1 ligand 1 (PD-L1) in renal cell carcinomas in predicting outcome of the patients is yet unclear. We analyzed the clinical and RNA-seq data of 522 kidney clear cell cancer, 259 kidney papillary cell carcinoma and 66 kidney chromophobe patients from The Cancer Genome Atlas (TCGA) database. In kidney clear cell cancer patients with high PD-L1 mRNA level and low PD-L1 mRNA level in tumors, the median overall survival periods were 45...

PURPOSE OF REVIEW: There is increasing recognition of the need for life-long care in patients who have congenital urological anomalies. This study looks at the factors surrounding transition and suggests those, which may improve the success. RECENT FINDINGS: One of the most challenging phases in this care is adolescence. There are the physical and psychological changes that all adolescents go through. Patients need medical surveillance through this time in order to ensure good care and patient safety...

BACKGROUND: Congenital malformations of the seminal vesicle are uncommon, and most of them are cystic malformations. If an insult occurs between the 4th and the 13 h gestational week, the embryogenesis of the kidney, ureter, seminal vesicle, and vas deferens could be altered. Cysts of the seminal vesicle may appear with a mass effect, dysuria, epididymitis, or obstruction of the gastrointestinal and genitourinary tracts. Approximately two thirds of them are associated with ipsilateral renal agenesis, because both the ureteral buds and seminal vesicles originate from the mesonephric (Wolffian) duct...

OBJECTIVE: To review epidemiology and management of urologic neoplasms in renal transplant candidates and recipients. MATERIAL AND METHODS: Relevant publications were identified through Medline ( and Embase ( database using the following keywords, alone or in association, "neoplasms"; "prostate cancer"; "renal carcinoma"; "renal transplantation"; "transitional carcinoma"; "waiting list". Articles were selected according to methods, language of publication and relevance...

The epithelial-mesenchymal transition (EMT) process has increasingly been examined due to its role in the progression of human tumors. Renal cell carcinoma (RCC) is one of the most common urological tumors that results in patient mortality. Previous studies have demonstrated that the EMT process is closely associated with the metastasis of RCC; however, the underlying molecular mechanism has not been determined yet. The present study revealed that interleukin (IL)-8 was highly expressed in metastatic RCC. IL-8 could induce the EMT of an RCC cell line by enhancing N-cadherin expression and decreasing E-cadherin expression...

INTRODUCTION: Transgender individuals are underserved within the health care system but might increasingly seek urologic care as insurers expand coverage for medical and surgical gender transition. AIM: To evaluate urology residents' exposure to transgender patient care and their perceived importance of transgender surgical education. METHODS: Urology residents from a representative sample of U.S. training programs were asked to complete a cross-sectional survey from January through March 2016...

Renal cell carcinoma (RCC) is the most common type of kidney cancer, about one third of the cases are diagnosed at advanced stages with metastases and effective treatments for metastatic RCC are lacking. The molecular events supporting RCC progression remain poorly understood. SPOP, an E3 ubiquitin ligase component, was recently showed to sufficiently promote RCC tumorigenesis, however, other potential functions of SPOP in RCC have not been studied. In the present investigation, by assessing the immunohistochemical staining of SPOP in urological tumors, we found the protein was highly expressed in RCC, in particular, it was specifically expressed in clear cell RCC...

Traditional factors that once explained men's sexual difficulties appear insufficient to account for the sharp rise in erectile dysfunction, delayed ejaculation, decreased sexual satisfaction, and diminished libido during partnered sex in men under 40. This review (1) considers data from multiple domains, e.g., clinical, biological (addiction/urology), psychological (sexual conditioning), sociological; and (2) presents a series of clinical reports, all with the aim of proposing a possible direction for future research of this phenomenon...

In recent years, there has been increasing interest in transitional urology, or how to best prepare patients with major congenital urologic diseases, such as bladder exstrophy and neuropathic bladder, to manage their own health care with adult urologists. However, common pediatric urologic conditions may be encountered by the adult urologist with more regularity. This review focuses on three relatively common conditions which may be identified in childhood, the consequences from which a patient may seek help from an adult urologist: cryptorchidism, varicocele, and Klinefelter syndrome...

INTRODUCTION: Though, bladder cancer is one of the most common urological malignancies, studies addressing the young age group bladder tumors are rare. Present study was done to determine the clinicoepidemiological aspects of bladder tumor diagnosed in young age patients and to compare these aspects with elderly patients. PATIENTS AND METHODS: Patients with urinary bladder tumor were selectively divided into two groups; young (<40 years) and elderly (>60 years)...

OBJECTIVE: To report 2 pediatric urology referral centers' experience on transitional cell carcinoma of the bladder (TCCB) in patients younger than 30 years, focusing on age-related prognostic factors. MATERIALS AND METHODS: Patients younger than 30 years affected by TCCB from January 1999 to December 2011 were investigated. Spearman's rank test and Kruskal-Wallis test were adopted for statistical analysis. RESULTS: Eighteen patients were identified (8 females, 10 males) and stratified by age at presentation: 5 in group A (12 years old and younger), 7 in group B (13-19 years), and 6 in group C (20-29 years)...

Bladder cancer (BC) is a common urologic tumor characterized by high risk of recurrence and mortality. Capsaicin (CPS), used as an intravesical drug for overactive bladder, was demonstrated to induce cell death in different cancer cells including BC cells.Here we found that treatment of high-grade BC cells with high dose of CPS triggers autophagy. Infact, the CPS treatment alters the redox homeostasis by inducing production of radicals, mitochondrial depolarization, alterations of ADP/ATP ratio and activation of AMPK pathway stimulating the autophagic process in BC cells...

Early detection is the key to improve the prognosis of kidney cancer. This study profiled and identified differentially expressed serum proteins in stage T1a renal cell carcinoma (RCC) using isobaric tags for relative and absolute quantification (iTRAQ)-based mass spectrometry. A total amount of 99 serum samples including 29 patients with ccRCC, 24 patients with a benign kidney mass, 28 patients with another type of urological tumor (20 cases of transitional cell carcinoma and 8 cases of prostate cancer or a male genital tumor), and 18 healthy controls were subjected to iTRAQ-based mass spectrometry...
