Bladder carcinoma is the most common malignancy of urinary tract. Approximately 75-85% patients with bladder cancer present a disease that confined to mucosa (stage Ta, in situ) or submucosa T1). These categories are grouped as nonmuscle invasive (NMIBC). Although management NMIBC tumours has significantly improved during past few years, it remains difficult predict heterogeneous outcome such tumours, especially if high-grade present. Transurethral resection initial treatment choice for...
Objective. This study aimed to explore the relationship between stone density and outcomes of percutaneous nephrolithotomy (PCNL) using Clinical Research Office Endourological Society (CROES) PCNL Global Study database. Material methods. Patients undergoing treatment were assigned a low [LSD, ≤ 1000 Hounsfield units (HU)] or high (HSD, > HU) group based on radiological primary renal stone. Preoperative characteristics compared in two groups. Results. Retreatment for residual stones was more...
The MCNP 6.2 event-by-event transport of electrons has been used for the first time to simulate energy imparted in low-density objects corresponding nanometric unit-density objects. It is shown that isolated atom assumption and use an average excitation based on stopping power, significantly alters value from excitations. This limits some extent micro- nanodosimetric applications, at least when excitations play important role. Simulated single-event distributions show pronounced anomalous...
Gamma-ray spectrometry is widely applied in several science fields, and particular non-destructive gamma scanning emission tomography of irradiated nuclear fuel. Often, a collimator used the experimental setup, to selectively interrogate region interest For optimization instrument design, as well for planning measurement campaigns, predictive models transmitted gamma-ray intensity through are needed. Commonly, Monte Carlo radiation transport tools accurate prediction transport, however, long...
Large renal oncocytomas are not very rare entities. To the best of our knowledge, we report one largest in English literature. The tumor was incidentally diagnosed and, based on preoperative clinical and radiographic findings, therefore considered to be a cell carcinoma. A 48-year-old Caucasian diabetic man had an abdominal ultrasound for chronic discomfort, which revealed large mass left kidney. An computed tomography scan contrast enhancing, well defined, heterogenous (16.5 × 13.9 cm)...
Abstract Irradiation testing of nuclear fuel is routinely performed in test reactors. For qualification and licensing accident-tolerant fuels or generation IV reactor fuels, an extensive increase irradiation foreseen order to fill the gaps existing validation data, both normal operational conditions identify limits. Gamma emission tomography (GET) has been demonstrated as a viable technique for studies behavior irradiated fuel, e.g., measurement fission gas release inspection under...
In the present work $^{165}\mathrm{Ho}(n,2n)$ reaction was studied experimentally and theoretically for population of ground state (${J}^{\ensuremath{\pi}}={1}^{+}$) $^{164}\mathrm{Ho}$ product nucleus, as well its isomeric (${E}_{ex}=139.8$ keV, ${J}^{\ensuremath{\pi}}={6}^{\ensuremath{-}}$). The cross sections both channels were measured at energies near threshold (${E}_{th}=8.04$ MeV), 10.1, 10.4, 10.7 MeV, higher than 17 17.1, 18.1, 19.0, 19.6 MeV. adopted method activation technique...
<title>Abstract</title> <bold>Background</bold> Patients with kidney disease and failure have often been excluded from randomized trials leaving practitioners limited data to navigate their decision-making at critical stages of patient’s lives. The concept target trial emulation has recently introduced implemented in Nephrology address questions the comparative effectiveness safety interventions during failure. However, reach, validity, application nephrology remains unknown warrants...
Abstract Background and Aims The concept of target trial emulation has recently been introduced implemented in nephrology as a complement to when randomized trials may not be feasible. Thereby critical questions the comparative effectiveness safety interventions during kidney failure can addressed. This methodological systematic review aims evaluate scope, validity robustness approach for studying outcomes patients with disease. Method MEDLINE, Embase, reference lists were searched up until...
Abstract Background Patients with kidney failure often lack robust evidence because they are excluded from randomized trials. Trial emulation provides an alternative approach to derive treatment effect estimates when trials cannot be conducted. Critical questions about the comparative efficacy and safety of interventions in now being answered using this or parts it. However, variations inconsistencies reporting cast doubt on reliability validity not derived The aim methodological systematic...
Ziele: Die endorektale MRT besitzt bekanntermaßen eine hohe Genauigkeit in der Erkennung eines organüberschreitenden Tumorwachstums. Zur Planung MRT-gesteuerter Prostatabiopsien wird hingegen Lokalisation Tumorherde gefordert. Ziel Arbeit war die Evaluierung diagnostischen T2w zur von Tumorherden anhand Großflächenprostatektomiepräparate. Methode: Es wurden 70 Patienten mit Prostatakarzinom vor radikaler Prostatektomie (radPx) mittels endorektalen Spule einschließlich axialer und coronarer...
