Abstract: Objective Discussion on maintenance dialysis patients with the feasibility of accepting surgery and perioperative management. Methods One-hundred-seventy-five maintenance dialysis patients (including hemodialysis and peritoneal dialysis) were selected into a retrospective study. Then we investigated their information related to the surgery, compared with the changes of hemoglobin、electrolyte、kidney function、 blood pressure between pre- and post-operation, record whether or not there were surgical complications, discuss the perioperative management and summarize the adjustment of dialysis programme during perioperative period. Results Among 175 cases of maintenance hemodialysis patients , 18 cases need surgical operation,accounting for 10.28% of dialysis patients.13 patients undergoing 18 cases of operations. Preoperative Hemoglobin (Hb) level were (97.35 t difference were found in the electrolytes、kidney functions and blood pressures between pre- and post-surgery. 2 cases of patients happened surgical complications which were hypotension and respiratory failure.1 patient died. The dialysis programmes need to be adjusted , different dialysis methods can be selected including continuous renal replacement therapy、without heparin hemodialysis、automatic peritoneal dialysis or continuous ambulatory peritoneal dialysis，according to the surgery conditions and the patientsConclusions Patients with maintenance dialysis have high risks of surgery. But after correct and appropriate perioperative management, most of them can tolerate surgery. Strengthen the perioperative management, especially the adjustment of dialysis modalities, will help to these patients to survive the perioperative period.
