Pyocystis, empyema cystis, vesical empyema are all terms that describe the purulent filled bladder that may develop in patients with defunctionalized bladders such as after supravesical urinary diversion without cystectomy or in patients with end-stage renal disease with anuria. It is a severe form of lower urinary tract infection. In addition to the local symptoms of suprapubic pain and malodorous discharge, the condition can be more serious with bacterial dissemination into the blood stream and ensuing sepsis and even mortality...

PURPOSE: There is conflicting evidence regarding long-term effects of unilateral nephrectomy such as cardiovascular diseases. Excessive increase in blood pressure (BP) during exercise called "hypertensive response to exercise" may be a sign of unborn hypertension and increased cardiovascular risk. Decrease in glomerular filtration rate (GFR) in patients with unilateral nephrectomy may be associated with disturbance of circadian BP changes without affecting the absolute levels of BP. We aimed to investigate the circadian BP changes and hypertensive response to exercise in normotensive patients with preserved renal functions who had undergone unilateral nephrectomy for other causes rather than organ donation...

PURPOSE: Cisplatin is a chemotherapeutic agent with potential nephrotoxicity. Delayed increase in serum creatinine after cisplatin administration shows that serum creatinine may not be a sufficient marker for early detection of nephrotoxicity. Urinary insulin-like growth factor binding protein-7 (IGFBP7) and tissue inhibitor of metalloproteinases-2 (TIMP-2) which are cell-cycle arrest biomarkers have been proposed recently for early detection of acute kidney injury (AKI). Herein, we evaluated urinary TIMP-2/IGFBP7 levels before and after cisplatin administration to patients with lung cancer and their role was examined in the early diagnosis of AKI...
