Is high accuracy of Vesical Imaging-Reporting and Data System (VI-RADS) sufficient for its implementation in the urological practice?

Aims. Currently, the only method used to differentiate between MIBC and NMIBC is transurethral resection of the bladder tumour (TURBT). Magnetic resonance and Vesical Imaging-Reporting and Data System (VI-RADS) would allow for discrimination between NMIBC and MIBC. We evaluate the sensitivity and specificity of VI-RADS in the diagnosis of muscle-invasive bladder cancer and discuss its value in everyday urological practice. Methods. 64 patients with bladder cancer (BC) were enrolled into this prospective study. Multiparametric magnetic resonance imaging (mpMRI) was performed before transurethral resection of the bladder tumour (TURBT) and evalu ated using the VI-RADS score. Score were compared to histopathology results. We evaluated the sensitivity, specificity, positive and negative predictive value of this system using both cut-off VI-RADS ≥ 3 and ≥ 4. Results. Sensitivity of 92.3% (95%CI: 64.0; 99.8), specificity of 81.4% (95%CI: 69.1; 90.3), positive predictive value of 52.2% (95%CI: 30.6; 73.2) and negative predictive value of 98.0% (95%CI: 89.1; 99.9) was determined using cut off VI RADS ≥ 3, while sensitivity of 76.9% (95%CI: 46.2; 95.0), specificity of 91.5% (95%CI: 81.3; 97.2), positive predictive value of 66.7% (95%CI: 38.4; 88.2), and negative predictive value of 94.7% (95%CI: 85.4; 98.9) was determined using cut-off VI-RADS ≥ 4. Based on our results, we consider the optimal cut-off point to be VI-RADS ≥ 3 with the overall prediction accuracy of 83.3% (95%CI: 72.7; 91.1). Conclusions. We acknowledge that mpMRI provides valuable information with regard to BC staging, however, despite its high overall accuracy, we do not consider the VI-RADS could replace TURBT in discrimination between non-muscle invasive and MIBC.Web of Science1671908

Business Plan Proposal for a Company

Bakalářská práce je návrhem podnikatelského záměru pro založení pojízdného baru. Jedná se o specifický bar kombinující prvky rychlého občerstvení a klasického baru. Práce je složena ze tří částí. Teoretická část bude vycházet z literární rešerše a budou zde vymezeny základní pojmy. Analytická část se bude zabývat analýzou trhu a jeho potřebami, přičemž budou využity nástroje SLEPT a SWOT analýzy. Návrhová část je pak vlastním zpracováním podnikatelského plánu.The bachelor thesisis is a proposal of the business plan for the intention to establish the mobile bar. This specific bar combines elements of fast food and classic bar. The thesis consists of three parts. Theoretical part is based on literary research and the elementary terms are defined here. The analytical part deals with market analysis and its needs, using SLEPT and SWOT analysis. The design part is then the proposal of business plan itself.

Intermittent catheterisation in older people 57 Intermittent catheterisation in older people: a valuable alternative to an indwelling catheter?

Abstract Objectives: to investigate whether intermittent catheterisation is a valuable alternative to an indwelling catheter in patients older than 70 years with post-void residuals more than 50% of the bladder capacity. Patients and methods: we retrospectively reviewed the medical records of 21 patients (14 women, 7 men) older than 70 years in whom intermittent catheterisation was initiated because of voiding dysfunction with post-void residuals more than 50% of the bladder capacity resistant to other treatment. Twelve patients mastered the technique of intermittent self-catheterisation, seven were catheterised by their partners and two by nurses. Results: the mean age of patients was 76.5 years (range 71-83 years) and the mean observation period with regard to intermittent catheterisation was 27.9 months (range 5-129 months). For those relying on intermittent catheterisation, the urinary tract infection rate was 0.84 per year and patient (range 0-3), and urinary continence was restored in all of the six previously incontinent patients. Eighteen of the 21 patients reported a significantly improved quality of life owing to the restoration of urinary continence, decreasing of daytime frequency, nocturia and urge, and the lowering of the urinary tract infection rate. Conclusions: intermittent (self-) catheterisation is a safe and valuable technique in older people with significant post-void residuals owing to detrusor underactivity. Urinary continence is restored, urge, daytime frequency and nocturia are decreased, and the urinary tract infection rate is diminished, resulting in improved quality of life. Therefore, intermittent (self-) catheterisation is strongly recommended in older people

ICS Educational Module : Electromyography in the assessment and therapy of lower urinary tract dysfunction in adults

Aim: To present the teaching module “Electromyography in the assessment and therapy of lower urinary tract dysfunction in adults.” This teaching module embodies a presentation, in combination with this manuscript. This manuscript serves as a scientific background review; the evidence base made available on ICS website to summarize current knowledge and recommendations. Methods: This review has been prepared by a Working Group of The ICS Urodynamics Committee. The methodology used included comprehensive literature review, consensus formation by the members of the Working Group, and review by members of the ICS Urodynamics Committee core panel. Results: Electromyography (EMG) is a method to record spontaneous or artificially induced electrical activity of the nerve-muscle unit or to test nerve conductivity. EMG of the anal sphincter using surface electrode is most widely used screening technique to detect detrusor-sphincter dyssynergia in urology. It is non-invasive and easy to perform. EMG methods using needle electrodes are reserved for diagnostics in well selected group of mainly neurogenic patients. These methods require expertise in the field of general EMG and are usually performed by neurologist and neuro-physiologist. The evidence in many aspects of use of EMG in urology remains sparse. Conclusions: Currently EMG methods rarely play a decision making role in selecting proper treatment of lower urinary tract dysfunction. With the current efforts to improve phenotyping of these patients in order to provide individualized treatment, the role of EMG could increase
