Chronic kidney disease (CKD) can be considered to be present if a patient has a glomerular filtration rate (GFR) <60 mL/min or markers of structural kidney disease that have been present for >3 months. These include proteinuria, haematuria and radiological abnormalities. CKD is an important global-health challenge. It is found in 10% of the global population. The age-standardized global prevalence of CKD stages 1-5 in adults aged 20 and older was 10.4% in men and 11.8% in women. The incidence of end-stage renal failure is increasing worldwide with an annual growth rate of 8%. In 2010, the total number of renal replacement therapy (RRT) patients worldwide amounted to 2.6 million, whereas the number of patients needing this treatment was estimated to be between 4.9 and 9.7 million, with the largest gap between need and supply of RRT in low-income countries, particularly in Asia and Africa. In 2013, Egypt was among the countries for which CKD was ranked in the top 10 for years of life lost (YLL, calculated by multiplying numbers of deaths by life expectancy at time of death in a reference population) due to premature death and disability-adjusted life years (DALYs) to reflect the degree of disability such as pain or functional limitations caused by each condition. Early detection and treatment of CKD can be implemented at minimal cost and will reduce the burden of ESRD, improve outcomes of diabetes and cardiovascular disease (including hypertension), and substantially reduce morbidity and mortality from non communicable diseases (NCDs). Diabetes and hypertension are the predominant risk factors for chronic kidney disease (CKD) globally. Infectious diseases resulting in glomerulonephritis are also important in low-income countries. However, in the past two decades, a severe form of CKD has been reported in individuals without these risk factors. CKD of unknown etiology (CKDu) affects adults in their third to fifth decade and is often fatal due to disease progression and lack of dialysis or transplant options in the involved geographic areas. CKDu has been reported in Sri Lanka, several Central American countries, the state of Andhra Prakesh in India and Egypt. Besides the conventional work up of CKD cases, renal biopsy is indicated in patients with CKD whose kidneys are normal or near normal in size, where the diagnosis cannot be made by other means. Renal biopsy definitely still plays the most vital and irreplaceable role in the investigations of cases with unexplained renal impairment. Despite a vastly variable biopsy results between patients, renal biopsy has helped in determining the best treatment and prognosis for the patients.
