Measurement and correlation of electrolytes in EPS and urine of patients with chronic prostatitis / 中华泌尿外科杂志

ABSTRACT

Objective To measure the concentration of electrolytes such as potassium,sodium,chloride,calcium in EPS and urine of patients with chronic prostatitis and to analyze the correlation of the electrolytes in different patient groups. Methods The concentrations of potassium,sodium,chloride and calcium in EPS and urine of 31 controls and 79 patients with prostatitis were measured and analyzed. Results There was no significant difference between the patients and normal controls in electrolytical concentration of potassium,sodium,calcium except chloride (P=0.001).The concentration of chloride in the patients was significantly higher than that in the normal controls.In the treatment effective group, potassium concentrations were decreased from 40.66?17.10 to 33.42?17.27 mmol/L after treatment.In the treatment ineffective group, potassium concentrations were (37.57?16.93)mmol/L before treatment and 50.66?18.77 mmol/L after treatment.Potassium concentrations were 36.02?12.36 and 48.90?16.93 mmol/L in the pain group and painless group,respectively.There were positive correlations between the concentrations of potassium and calcium of EPS,sodium and chloride of urine as well. Conclusions The concentrations of potassium in EPS are obviously different between the effective group and ineffective group or the pain group and painless group.There is a close relationship between the concentration of potassium and calcium of EPS,sodium and chloride of urine; and they are positively correlated.
