PD-related hydrothorax is a rare but seriouscomplication in PD patients, produced by the movement of peritoneal dialysatethrough pleuroperitoneal fistulas. In previous reports, patients with hydrothoraxsecondary to PD were usually recommended to discontinue PD and transfer tohemodialysis (HD). Herein, we describe another method of managing thiscomplication—with an adjusted PD prescription and continuous drainage ofpleural effusion, patients could continue PD without recurrence of hydrothorax.CASE SUMMARY In this report, we present the medical records of 2 patients with hydrothoraxsecondary to PD. We recommended intermittent PD with continuous drainage ofpleural effusion. A type 18Ga soft catheter was placed to drain pleural effusion.Ultrasound-guided thoracentesis was performed, and the soft catheter was placedin the pleural cavity for a long period (3 mo and 2 mo, respectively). The pleuralcatheter was removed when no fluid was drained from the pleural cavity. Afterseveral months, pleuroperitoneal fistulas were closed in both patients and PD wascontinued. These patients did not transfer to HD, had no recurrence ofhydrothorax and were still treated with PD after 1 year.CONCLUSION These 2 case reports show that continuous drainage of pleural effusion with an18Ga soft catheter is a useful method for hydrothorax secondary to PD.展开更多
