The regulation of the acid\u2013base balance involves primarily the lungs and kidneys, and is strictly integrated via the endocrine and nervous systems. Crucial theoretical concepts have been developed to describe these functions, for example the Base Excess (BE) for the interpretation of the blood gas analysis or the Net Acid Excretion (NAE) for the interpretation of the kidney contribution to acid\u2013base homeostasis. However, these concepts, coming from different research fields, have been insufficiently integrated. The present review collects information about the reciprocal correlation between respiratory and urinary parameters under physiological and common pathological conditions. A case in point will be made for metabolic acidoses, a heterogeneous group of disturbances whose interpretation would greatly benefit from the integration of information provided by the blood gas analysis with that provided by urinalysis, including the measurement of net acid excretion and urinary ammonium.<\/jats:p>","DOI":"10.14814\/phy2.70885","type":"journal-article","created":{"date-parts":[[2026,5,19]],"date-time":"2026-05-19T04:26:09Z","timestamp":1779164769000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The kidney and the balance of sulfur and nitrogen as fundamental components of\n                    <scp>pH<\/scp>\n                    homeostasis"],"prefix":"10.14814","volume":"14","author":[{"given":"Vincenzo","family":"Graziano","sequence":"first","affiliation":[{"name":"Department of Molecular and Clinical Medicine Sapienza University of Rome and UOC Nefrologia e Dialisi, Sant'andrea Hospital  Rome Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonio","family":"Angeloni","sequence":"additional","affiliation":[{"name":"Department of Wellbeing, Health and Environmental Sustainability Sapienza University of Rome and UOC Patologia Clinica, Policlinico Umberto I  Rome Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paolo","family":"Men\u00e9","sequence":"additional","affiliation":[{"name":"Department of Molecular and Clinical Medicine Sapienza University of Rome and UOC Nefrologia e Dialisi, Sant'andrea Hospital  Rome Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0431-6048","authenticated-orcid":false,"given":"Andrea","family":"Bellelli","sequence":"additional","affiliation":[{"name":"Department of Biochemical Sciences \u201cA.
