We address here its stability over time and the validity of the usual method of clinical measurement, as proposed by Durand in 1992 but never specifically validated. We performed this validation by comparing Durand\u2019s method and direct measurements with a central venous pressure system. We performed a total of 250 measurement pairs in 50 patients with different intraperitoneal volumes plus in-vitro measurements with a simulated peritoneum. Absolute differences between the two systems in vivo were 0.87 \u00b1 0.91 cmH\n                    <jats:sub>2<\/jats:sub>\n                    O (range 0\u20135 cmH\n                    <jats:sub>2<\/jats:sub>\n                    O); only 6.4% of them were \u22653 cmH\n                    <jats:sub>2<\/jats:sub>\n                    O. In vitro results for both methods were identical. We also compared IPP measurements in the same patient separated by 1\u20134 h (514 measurement pairs in 136 patients), 1 week (92 pairs in 92 patients), and 2 years (34 pairs in 17 patients). Net differences of measurements separated by hours or 1 week were close to 0 cmH\n                    <jats:sub>2<\/jats:sub>\n                    O, with oscillations of 1.5 cmH\n                    <jats:sub>2<\/jats:sub>\n                    O in hours and 2.3 cmH\n                    <jats:sub>2<\/jats:sub>\n                    O in 1 week. IPP measured 2 years apart presented a net decrease of 2.5 \u00b1 4.9 cmH\n                    <jats:sub>2<\/jats:sub>\n                    O, without correlation with body mass index changes or any other usual parameter of PD. In hours, 7% of IPP differences were &gt;3 cmH\n                    <jats:sub>2<\/jats:sub>\n                    O, 22% in 1 week, and 50% in 2 years. In conclusion, Durand\u2019s method is precise enough to measure IPP in peritoneal dialysis. This parameter is not stable over long timescales, so it is necessary to use recent measurements.\n                  <\/jats:p>","DOI":"10.1177\/0896860820973120","type":"journal-article","created":{"date-parts":[[2020,11,29]],"date-time":"2020-11-29T00:43:27Z","timestamp":1606610607000},"page":"427-431","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["Intraperitoneal pressure: Stability over time and validation of Durand\u2019s measurement method"],"prefix":"10.1177","volume":"41","author":[{"given":"Alicia","family":"Sobrino-P\u00e9rez","sequence":"first","affiliation":[{"name":"Servicio de Nefrolog\u00eda, Hospital Cl\u00ednico Universitario de Valladolid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alfonso","family":"P\u00e9rez-Escudero","sequence":"additional","affiliation":[{"name":"Research Center on Animal Cognition (CRCA), Center for Integrative Biology (CBI), Toulouse University, CNRS, UPS, Toulouse, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lucila","family":"Fern\u00e1ndez-Arroyo","sequence":"additional","affiliation":[{"name":"Servicio de Nefrolog\u00eda, Hospital Cl\u00ednico Universitario de Valladolid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ana","family":"Dorado-Garc\u00eda","sequence":"additional","affiliation":[{"name":"Servicio de Nefrolog\u00eda, Hospital Universitario Rio Hortega de Valladolid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Berta","family":"Mart\u00edn-Alc\u00f3n","sequence":"additional","affiliation":[{"name":"Servicio de Nefrolog\u00eda, Complejo Asistencial Universitario de Palencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carmen","family":"Guti\u00e9rrez-Mart\u00edn","sequence":"additional","affiliation":[{"name":"Servicio de Nefrolog\u00eda, Complejo Asistencial de Segovia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carmen","family":"S\u00e1nchez-Fonseca","sequence":"additional","affiliation":[{"name":"Servicio de Nefrolog\u00eda, Complejo Asistencial de \u00c1vila, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristina","family":"Barrios-Rebollo","sequence":"additional","affiliation":[{"name":"Servicio de Nefrolog\u00eda, Complejo Asistencial Universitario de Burgos, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8580-8954","authenticated-orcid":false,"given":"Vicente","family":"P\u00e9rez-D\u00edaz","sequence":"additional","affiliation":[{"name":"Servicio de Nefrolog\u00eda, Hospital Cl\u00ednico Universitario de Valladolid, Spain"},{"name":"Departmento de Medicina, Dermatolog\u00eda y Toxicolog\u00eda, Universidad de Valladolid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"on behalf of Group PIPDPCyL","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2020,11,28]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.nefro.2017.05.014"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.3747\/pdi.2012.00192"},{"key":"e_1_3_3_4_2","first-page":"46","article-title":"Intraperitoneal hydrostatic pressure and ultrafiltration volume in CAPD","volume":"9","author":"Durand PY","year":"1993","unstructured":"Durand PY, Chanliau J, Gamberoni J, et al.
