BACKGROUND: Perioperative antibiotic prophylaxis (PAP) is an integral part of kidney transplantation to prevent surgical site infections (SSI). In July 2015, we changed our standard from a multiple-dose to a single-dose (SD) prophylaxis. Here, we report on results with both regimens and a related survey among Eurotransplant renal transplantation centers. METHODS: From July 2015, all kidney graft recipients of our center were scheduled to receive SD i.v. cefazolin (group SD, n = 107)...

BACKGROUND: The urologic management of children with spinal cord injury (SCI) differs from that of the adult insofar as the care involves a developing organ system and will be ongoing for years. Preservation of renal function as well as prevention of urinary tract infection in concert with both bladder and bowel continence are the essential guiding principles. METHODS: This is a non-systematic review of the literature and represents expert opinion where data are non-existent...

PURPOSE: Clear cell, papillary cell, and chromophobe renal cell carcinomas (RCCs) have now been well characterised thanks to large collaborative projects such as The Cancer Genome Atlas (TCGA). Not only has knowledge of the genomic landscape helped inform the development of new drugs, it also promises to fine tune prognostication. METHODS: A literature review was performed summarising the current knowledge on the genetic basis of RCC. RESULTS: The Von Hippel-Lindau (VHL) tumour suppressor gene undergoes bi-allelic knockout in the vast majority of clear cell RCCs...

BACKGROUND: Despite the high utilisation of ureterorenoscopy (URS) in interventional stone treatment, there is little evidence of any link between annual hospital volume and outcome. METHODS: From January to April 2015, data from 307 URS patients were prospectively recorded in the multicentre observational BUSTER-Trial (Benchmarks of ureterorenoscopic stone treatment-results in terms of complications, quality of life, and stone-free rates). The best threshold value for annual hospital volume with an independent effect on the outcome (measured on stone-free and complication rates) of our study group was established with logistic regression...

OBJECTIVE: It has been hypothesized that endothelial dysfunction and pelvic atherosclerosis may contribute to lower urinary tract symptoms (LUTS). We assessed the relationship between cardiovascular risk factors and LUTS severity in male patients presented to urology clinic. METHODS: It is a cross-sectional study on patients who presented between 2013 and 2015 with LUTS. A total of 1176 male patients were encountered, and 966 were included for analysis after excluding patients with urinary tract malignancy, urethral stricture, bladder stone and history of urinary tract surgery...

PURPOSE: To investigate, if and how omitting gadolinium-based contrast agents (GBCA) and dynamic contrast-enhanced imaging (DCE) influences diagnostic accuracy and tumor detection rates of prostate MRI. METHODS: In this retrospective study, 236 patients were included. The results of biparametric (bpMRI) and multiparametric magnetic resonance imaging (mpMRI) were compared using the PI-RADS version 2 scoring system. The distribution of lesions to PIRADS score levels, tumor detection rates, diagnostic accuracy and RoC analysis were calculated and compared to the results of histopathological analysis or 5-year follow-up for benign findings...

PURPOSE: Uric acid (UA) calculi can be referred to chemolitholysis rather than invasive treatment. Dual-energy computed tomography (DECT) may be able to distinguish between UA and non-UA (NUA) calculi. The aim of this study was to evaluate the validity of third-generation DECT for the first time and to investigate whether combining DECT with clinical parameters can increase its predictive accuracy. MATERIALS AND METHODS: All patients who presented to our emergency department between January 2015 and March 2017 with urinary stones were prospectively included in this observational study and underwent DECT with subsequent interventional stone removal...

PURPOSE: Along with a number of other malignancies, the term "oligometastatic" prostate cancer has recently emerged. It represents an attempt to define a subtype of cancer with a limited metastatic load that might perform more favorably than a distinctly disseminated disease, or even one that may be managed in a potentially curative way. Since there is currently a knowledge gap of what imaging modalities should be utilized to classify patients as having this type of tumor, we aimed to shed light on the role of conventional and marker-based imaging in the setting of synchronous oligometastatic prostate cancer as well as summarize the available evidence for its clinical application...

INTRODUCTION: Recent trials have emphasized the importance of a precise patient selection for cytoreductive nephrectomy (CN). In 2013, a nomogram was developed for pre- and postoperative prediction of the probability of death (PoD) after CN in patients with metastatic renal cell carcinoma. To date, the single-institutional nomogram which included mostly patients from the cytokine era has not been externally validated. Our objective is to validate the predictive model in contemporary patients in the targeted therapy era...

PURPOSE: The enzyme 5-α reductase type 2 (5-AR 2) plays a key role in the development and maintenance of the prostate gland. We evaluated the level 5-AR 2 protein expression and the relationship between methylation of the 5-AR 2 gene-promoter and 5-AR 2 protein expression of benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: A total of 37 prostate samples were evaluated. These included 22 samples from men undergoing transurethral prostate resections and 15 non-cancerous transition-zone human prostate tissue samples taken following radical prostatectomy...

PURPOSE: Patients with localised renal cell carcinoma (RCC) can expect excellent oncologic outcomes. As such, there has been a shift towards maximising health-related quality of life (HRQoL). A greater understanding of HRQoL outcomes associated with different treatment options for RCC can facilitate patient-centred care, shared decision-making and enable cost utility analyses to guide health policies. The aim of this literature review was to evaluate the evidence regarding HRQoL following different management strategies for localised RCC...

PURPOSE: To review the available data on non-surgical management for neurogenic bladder in patients with spinal cord injury (SCI). Before the introduction of urinary catheters and antibiotics, neurogenic bladder was one of the main culprits for death in those patients with SCI. Currently, the management of neurogenic bladder is focused in improving quality of life and preserving renal function. METHODS: A literature review was performed and therapeutic management for neurogenic bladder was divided in six sections: (1) intermittent bladder catheterization; (2) indwelling catheters; (3) condom catheter drainage; (4) reflex voiding and bladder expression with Valsalva or Credé; (5) oral drug therapy of the spinal cord injured bladder; and (6) botulinum neurotoxin (BoNT)...
