Urothelial tumors of the renal pelvis and the ureter do not differ from those of the urinary bladder concerning histopathological phenotypes. However, with respect to tumor biology there are relevant differences between the two tumor locations. The originating tissue (urothelium) of the bladder and of the upper urinary tract varies significantly with respect to developmental origin, morphology and physiological function. Specific pathways of tumorigenesis (e.g. hereditary non-polyposis colorectal cancer, HNPCC) and tumor propagation (seeding) are described for tumors of the upper urinary tract. Clinical epidemiological data indicate specific correlations between the two tumor locations.

We are observing the largest worldwide wave of migration ever. Displaced persons usually do not have access to general health care and are faced with a lack of hygienic conditions and infection control while fleeing, which leads to an accumulation of "exotic" infectious diseases. The number of patients with tuberculosis (TB) had declined for many years in Germany; however, increasing numbers of cases have recently been observed. For urologists, of course, the manifestations of urogenital TB (UGTB) are of particular interest. Therefore, the basics regarding diagnosis and therapy of UGTB are discussed in this article and explained using case studies. The second important "exotic" infectious disease that urologists are increasingly facing is schistosomiasis. The larvae (found mostly in stagnant water) penetrate through intact human skin, mature and migrate into the liver, from where they immigrate into the venous capillaries of the intestine, the small pelvis, the bladder wall and the distal ureter, and there cause chronic inflammation. All urologists should be familiar with the diagnosis, therapy and prophylaxis of urogenital schistosomiasis and the oncogenesis of schistosomiasis-associated bladder carcinoma.
