Abstract: 〔Abstract〕Objective: To investigate the attainment rate of calcium, phosphorus and intact parathyroid hormone（iPTH）levels in
peritoneal dialysis（PD）patients from the First Affiliated Hospital of Dali University, and to explore the effect of residual urine volume
on calcium & phosphorus metabolism. Methods: We collected the clinical data of 88 patients from October 2017 to March 2018 who
received PD for more than 3 months and had regular follow-up in our blood purification center and made a cross-sectional study. The
attainment rates of serum calcium, phosphorus and iPTH levels were calculated according to K/DOQI standard, and compared with the
results from the domestic and foreign studies. According to the residual urine volume patients were divided into two groups（urine
volume <100 mL/d for the anuria group, urine volume ≥100 mL/d for the urine group）, and then serum calcium, phosphorus and iPTH
levels between the two groups were compared. Results: The proportions of patients who have reached the normal serum calcium,
phosphorus and iPTH concentrations were 44.3%, 40.9% and 12.5%, respectively. 4.5% patients reached all the target levels for
calcium, phosphorus and iPTH. The attainment rates of calcium and phosphorus in our research was similar to the results of other
studies, but the attainment rate of iPTH was comparatively lower. Serum phosphorus and the calcium - phosphate product
concentrations of the patients without urine were higher than those of the urine group（P<0.05）. Conclusion: The control of calcium
and phosphorus metabolic disorder and secondary hyperparathyroidism in PD patients in our center is poor, which needs to be further
strengthened.
