The curious right-sided predominance of peritoneal dialysis-related hydrothorax

Steven Guest. Clin Kidney J. 2015 Apr.

Abstract

A known complication of peritoneal dialysis is the movement of dialysate into the pleural space, termed hydrothorax. Peritoneal dialysis-related hydrothorax is almost uniformly right-sided and represents one of many presentations of the porous diaphragm syndrome. In addition to diaphragm porosity, the inherent intestinal circulation, lower hydrostatic pressure in the right upper quadrant and liver capsule may contribute to this right-sided predominance. Similar right-sided presentations have been described in Meigs syndrome, bilious effusions with gastric or duodenal perforations, hepatic hydrothorax and nephrotic syndrome-related chylothorax. PD-related hydrothorax can be repaired by pleurodesis or video-assisted thoracoscopy followed by resumption of peritoneal dialysis.

Keywords: diaphragm; hydrothorax; peritoneal dialysis; pleural effusion.
