Abstract: Objective To investigate the situation of maintenance hemodialysis (MHD) patients, a cross-sectional study was conducted and data were analyzed. Methods We invstigated 242 MHD patients whose dialysis age more than 3 months and treated in this hemodialysis centre in August 2013 and compared these data with the guidelines. We also analyzed age, gender, years for dialysis, Hb, renal function, serum Ca, serum phosphate, Ca×P product and iPTH in these patients. Results In the 242 patients, there are 134 (55.4%) male, 108 (44.6%) of female, and the male to female ratio was 1.24:1. The most common causes of end-stage renal diseases (ESRD) in these hemodialysis patients were chronic glomerulonephritis(54.54%)，diabetic nephropathy(10.33)，and hypertensive renal damage (7.85%). 148(61.16%) cases of Hb, 208(85.12%) cases of calcium and phosphorus metabolism（Including patients with hypercalcemia, hypocalcemia, hyperphosphatemia and hypophosphatemia）, 96(39.66%)cases Ca×P product and 110(46.61%)cases of iPTH couldn’t meet the requirements of the guidelines. Conclusions In Kunshan, there are more male patients and MHD patients are more younger. The main causes of ESRD patients on hemodialysis are still chronic glomerulonephritis. There are large number of patients with low compliance rate of Hb and disorders of calcium and phosphorus metabolism and secondary hyperparathyroidism.
