Objective To investigate the prevalence of gallbladder stone in dialysis patients, determine whether it is higher than that in the general population, find out the difference of prevalence between hemodialysis and peritoneal dialysis patients, and analyzes the possible causes. Methods We analyzed the prevalence of gallbladder stone in 358 dialysis patients (126 cases of hemodialysis and 232 cases of peritoneal dialysis) followed up in our hospital from January 2009 to October 2012. And we compared it with 376 patients diagnosed with chronic kidney disease stage 5 (CKD5) and the general population. Results The prevalence of gallbladder stone in dialysis patients followed up in our hospital was 23.5%, which was higher than CKD5 patients (P=0.002). The prevalence was significantly greater in dialysis patients than that in the general population (P<0.000 5). In the dialysis patients who were younger than sixty years old, the prevalence of gallbladder stone in peritoneal dialysis patients was obviously higher than that in the hemodialysis patients (P<0.05). The albumin level was significantly lower in peritoneal dialysis patients than in the hemodialysis patients. At the same time, cholesterol, low density lipoprotein, and the ratio of low density lipoprotein to high density lipoprotein were much higher with statistical significance. Logistic regression analysis showed that increasing age (OR=2.581, P=0.001), female (OR=2.554, P=0.000), the primary disease (diabetes mellitus) (OR=1.947, P=0.044) and dialysis period (OR=1.000, P=0.006) were risk factors for gallbladder stone in dialysis patients. Conclusion The prevalence of gallbladder stone in dialysis patients is higher than that in the general population. Peritoneal dialysis patients have more risk factors to get gallbladder stone than hemodialysis patients. Risk factors for gallbladder stone in dialysis patients are increasing age, female, primary disease (diabetes mellitus), dyslipidemia, hypoalbuminemia, long dialysis period and so on.
