A large intraperitoneal residual volume hampers adequate volumetric assessment of osmotic onductance to glucose.

CONCLUSIONS: A large RV leads to significant overestimation of OCG using the double mini-PET, potentially reducing the ability of OCG to identify patients with progressive fibrosis in the peritoneal interstitium. On the other hand, sieving of the dialysate sodium, a biochemical surrogate for OCG, is independent of the RV and may therefore be more reliable. A call for caution is warranted in patients with a large RV to avoid misinterpretation of OCG values derived from the double mini-PET. PMID: 29674410 [PubMed - as supplied by publisher]
