title: Eight year review of hemodialysis: treated patients in a tertiary center in Southern Nigeria.
abstract: BACKGROUND
  Hemodialysis (HD) is the readily available modality of renal replacement therapy in Nigeria today. The number of centers for HD continues to increase, but the majority is still located in the big cities and towns.
  
  
  METHODS
  A retrospective descriptive study in which records of patients on HD from 2004 to 2011 were reviewed. Data in respect of patients' sex, age, occupation and etiology of kidney disease were collected. Data were analyzed using Statistical Package for the Social Sciences statistical software version 16 (SPSS Inc, Chicago IL).
  
  
  RESULTS
  A total of 1278 new patients were admitted for HD over the period of review; 60.9% (778) were males and 39.1% (500) females. Mean age of male patients was significantly higher than that of the females (P < 0.01). Those under the age of 40 years constituted 45.4% (580) of the study population, whereas 43.8% (560) were unskilled workers. Nearly 81.1% had CKD while 18.9% (241) had acute kidney injury (AKI). The most common cause of CKD and AKI were chronic glomerulonephritis (CGN) and sepsis respectively.
  
  
  CONCLUSIONS
  This review showed a preponderance of males in the dialyzed population with males significantly older than the female patients. Patients aged ≤ 40 years and unskilled workers formed a large proportion of the population of HD treated patients. CGN and sepsis were the most common causes of CKD and AKI respectively.
