Abstract:

Peritoneal dialysis (PD) is an effective treatment option for patients with endstage renal disease.Hydrothorax occurs in 16%～6% of patients who undergo Continuous Ambulatory Peritoneal Dialysis(CAPD),and approximately half of these patients are forced to permanently exchange CAPD for haemodialysis.Possible pathogenetic mechanisms include congenital diaphragmatic defects,a disorder of lymphatic drainage,and pleuroperitoneal pressure gradient.Usually,the patients may remain asymptomatic or have sudden dyspnea,decrease in ultrafiltration,or pleuritic chest pain. Effective diagnostic methods,includeing high glucose concentration of the pleural fluid，chest radiograph,CT,MRI,peritoneogram with Tc99mMAA,are useful to diagnose hydrothorax.Searching for a simple and valid way to treatment pleural leakage has become particularly important.
