ObjectiveTo evaluate the safety and efficacy of total hip arthroplasty (THA) in patients with end stage renal disease (ESRD).MethodsBetween December 2009 and May 2016, 30 THAs were performed in 28 patients with dialysis-dependent renal failure (18 patients) or renal transplantation (10 patients). A retrospective case control study was carried out to compare these 28 ESRD patients (ESRD group) with a matched cohort of 28 nonrenal patients (control group). There was no significant difference in gender, age, hip side, American Society of Anesthesiology (ASA) classification, comorbidities, and preoperative Harris score and hemoglobin (Hb) level between 2 groups ( P>0.05). The complications during hospitalization, Hb level changes, perioperative transfusion rate, hospital stay, and hospitalization costs in 2 groups were evaluated; and the creatinine changes of dialysis patients in ESRD group were evaluated. During the follow-up period, 90 days readmissions, periprosthetic infection, prosthesis loosening, hip Harris score, and deaths were recorded.ResultsThere was no loss of follow-up. The mean postoperative follow-up of ESRD group was 3.4 years (range, 1.0-7.4 years) and control group was 3.5 years (range, 1.0-7.4 years). Differences in hospital stay and the drop of Hb was not significant between 2 groups ( P>0.05). The hospitalization costs and perioperative transfusion rate were significantly higher in ESRD group than in control group ( P<0.05). There was no significant difference in creatinine value of dialysis patients in ESRD group between pre- and post-operation ( t=1.804, P=0.089). At last follow-up, the Harris score was significantly higher than preoperative score in both groups ( P<0.05); however, there was no significant difference in Harris score between groups ( t=1.278, P=0.207). In ESRD group, 5 patients presented complications, 1 patient was readmitted to hospital, and 2 patients died during the follow-up. In control group, 1 patient presented complications, and there was no 90 days readmission and no death. During the follow-up period, there was no loosening or revision in 2 groups and the prosthesis was in good position.ConclusionTHA can improve joint function and life quality of ESRD patients, but the risks of operation, perioperative complications, transfusion rate, and cost are high. Correct perioperative evaluation and management can help ESRD patients safely go through the perioperative period.
