PURPOSE: Posterior acoustic shadow width has been proposed as a more accurate measure of kidney stone size compared to direct measurement of stone width on ultrasound (US). Published data in humans to date have been based on a research using US system. Herein, we compared these two measurements in clinical US images. METHODS: Thirty patient image sets where computed tomography (CT) and US images were captured less than 1 day apart were retrospectively reviewed. Five blinded reviewers independently assessed the largest stone in each image set for shadow presence and size...

PURPOSE: Often PIRADS 3 findings are usually followed up with further MRIs of the prostate. Current guidelines do not state an optimal interval between the initial MRI and the follow-up MRI. The aim of this study was to find out if PIRADS 3 lesions evolve over time and to determine how long the optimal interval between initial MRI and follow-ups should be. METHODS: In this retrospective study, 141 consecutive patients were included who underwent at least one follow-up MRI after an initial PIRADS 3 finding...

PURPOSE: The only RCT available on complete bladder neck preservation (cBNP) during radical prostatectomy reported superior continence and QoL outcomes in the first 12 months after cBNP. We provide the first data on long-term urinary continence, QoL and biochemical recurrence (BCR) after complete bladder neck preservation in a randomised controlled cohort. METHODS: After approval by IRB, 199 men recruited for the randomised, controlled single-blind Heidelberger cBNP Study had prostatectomy performed with (cBNP) or without (noBNP) complete bladder neck preservation...

PURPOSE: To understand the longitudinal renal function trends in patients undergoing radical nephroureterectomy (RNU) and identify clinicopathologic characteristics associated with estimated glomerular filtration rate (eGFR) recovery. METHODS: 147 patients were available for analysis. Longitudinal eGFR trends were assessed by plotting each patient's eGFR measurements over time. The patient population was dichotomized using eGFR < 60 ml/min/1.73 m2 versus ≥ 60 ml/min/1...

PURPOSE: Prostate cancer chemoresistance is a major contributor to the poor survival of patients. MicroRNAs (miRNAs) play an important role in regulating cancer resistance. Here we aim to explore the role and mechanism of miR-199a in regulating prostate cancer resistance. METHODS: MiR-199a expressions in human prostate cancer tissues and cell lines were investigated with real-time PCR (RT-PCR). MiR-199a was ectopically overexpressed in PC3 cells, and resistance to paclitaxel (PTX) was evaluated consequently...

BACKGROUND: The cytokine system RANKL (receptor activator of NF-κB ligand), its receptor RANK and the antagonist OPG (osteoprotegerin) play a critical role in bone turnover. Our investigation was conducted to describe the gene expression at primary tumour site in prostate cancer patients and correlate the results with Gleason Score and PSA level. METHODS: Seventy-one samples were obtained from prostate cancer patients at the time of radical prostatectomy and palliative prostate resection (n = 71)...
