Many changes have been made during these last years and concepts for understanding bladder cancer have evolved. We make an update with the latest findings of the WHO (World Health Organistaion) 2016, ICCR (International Collaboration on Cancer Reporting) and other official organisms and try to show the latest developments. In this document we provide new consensus guidelines and insights. We kept this document short and concise providing consensus guidelines to clinicians for the best patient care, it should be easy to understand for a non pathologists. We focussed on several burning issues, such as the anatomical and histological understanding of the bladder wall, the prognostic significance of grading and the most challenging problems in staging, we underline our needs from the clinicians such as clinical information, we further discuss the histological subtypes of bladder cancer, which is an extremely important issue in the light of molecular classifications and give prognostic insights. Furthermore, we discuss the ICCR worldwide consensus reporting, urinary cytology with the Paris system and several issues such as frozen section specimen.

Incidence rates of kidney cancer vary in global standards more than tenfold, the highest worldwide rates are repeatedly registered in the Czech Republic (hereafter CR) and in other geographically neighbouring countries in Central Europe, including the Slovak Republic (hereafter SR). The aim of the study was to analyse the changes in time trends of incidence and mortality from kidney cancer in two geographically close countries (CR and SR) and to compare detected differences with the worldwide data. In spite of high rates of incidence and its global growth in analyses in 1980 - 2005, the character of its progress in time was changed in both countries. While in 1980 - 1994 the incidence of kidney cancer in males and females in both analysed countries increased significantly, after 1994 (to 2005) stagnation in males in SR and significant slowdown of its growth in males in CR were reported. In females in SR after 1994 significant slowdown of the incidence growth was reported and in CR there was even its non-significant fall. Mortality trend in both sexes in both countries in 1980-2005 was slower than the incidence. After 1994 (to 2005) in males in SR statistically non-significant slowdown of mortality growth was reported, in CR it was statistically significant fall of mortality rates. In women after 1994 (to 2005) statistically non-significant decrease was reported, in CR the decrease was significant. The increase of total incidence of the disease is not explained only by the growth of asymptomatic localized tumors due to high quality diagnostic methods, but it likely reflects actual growth of new cases of the disease. Assumed partial cause of the mortality stabilization and slowdown of the incidence growth after its previous culmination in 1994 is the decline of smoking and obesity prevalence in the last decades in men, although this fact does not reflect situation in women. More striking mortality decrease in CR in comparison with SR might be influenced by potentially more radical surgical therapy (rate of the amount of surgery within primary therapy according to the data in National Cancer Registry CR raises, in SR the data are not available) and by more significant increase of the disease rate in the clinical stages I and II in CR (in SR only short-time data are available).

Objectives: To identify factors involved in reno-pulmonary interactions during mechanical ventilation. Materials and methods: The study included a total of 25 domestic piglets. The animals were divided into three groups based on different strategies of ventilation. Group A; spontaneously breathing piglets; group B animals ventilated with tidal volume of 6 ml.kg-1 and group C with animals ventilated with tidal volume 10 ml.kg-1. Clini- cal monitoring and laboratory tests were performed for all groups at baseline and then at 1 hour and 12 hours for groups B and C. Ventilation indices, hemodynamics, urine output, creatinine clearance, glomerular fi ltration index, fractional excretion of sodium, free water clearance and tissue samples were recorded. The data ob- tained were statistically analysed. Results: Lower creatinine clearance and renal indices were seen in group B (p < 0.05) and in group C (p < 0.001) at 1 hour, and a difference in urine output for group C (p < 0.01) compared to group A was observed. At 12 hours, there was a further reduction in creatinine clearance and renal indices for group B (p < 0.05) and group C (p < 0.01). The lung mechanics and hemodynamics were not signifi cantly infl uenced. Conclusions: The study showed a causal relationship between renal dysfunction and positive pressure mechani- cal ventilation with respect to tidal volume and time (Tab. 4, Fig. 2, Ref. 17).
