Whether simple water ingestion is a potential therapeutic strategy for individuals with autosomal dominant polycystic kidney disease (ADPKD) is unknown. In this study, a simple method to quantify the amount of water to achieve a specific mean urine osmolality target in patients with ADPKD was developed and tested.<\/jats:p>\n <\/jats:sec>\n \n Design, setting, participants, & measurements<\/jats:title>\n In eight ADPKD patients eating typical diets, osmolality and volume were measured in 24-hour urine collections. The amount of additional ingested water required daily to achieve a mean urine osmolality of 285 \u00b1 45 mosm\/kg was determined. Participants were instructed to distribute the prescribed water over waking hours for each of 5 days. Blood chemistries, 24-hour urine collections, BP, and weight were measured before and after the period of supplemental water intake.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Five patients achieved the 285 mosm\/kg urine target without difficulty. Mean urine osmolality decreased and mean urine volume increased; serum sodium, weight, and BP were unchanged. Daily osmolar excretion remained constant, indicating a stable\n ad lib<\/jats:italic>\n dietary intake of solutes and protein over the 2-week study period.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n The amount of additional water needed to achieve a urine osmolality target can be approximated from the urine osmolar excretion in ADPKD patients eating typical diets, providing a quantitative method to prescribe supplemental water for such individuals.<\/jats:p>\n <\/jats:sec>","DOI":"10.2215\/cjn.03950510","type":"journal-article","created":{"date-parts":[[2010,9,28]],"date-time":"2010-09-28T20:55:35Z","timestamp":1285707335000},"page":"192-197","source":"Crossref","is-referenced-by-count":71,"title":["Water Prescription in Autosomal Dominant Polycystic Kidney Disease"],"prefix":"10.2215","volume":"6","author":[{"given":"Connie J.","family":"Wang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Catherine","family":"Creed","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Franz T.","family":"Winklhofer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jared J.","family":"Grantham","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-26-20230811","doi-asserted-by":"crossref","first-page":"148","DOI":"10.2215\/CJN.00330705","article-title":"Volume progression in autosomal dominant polycystic kidney disease: The major factor determining clinical outcomes","volume":"1","author":"Grantham","year":"2006","journal-title":"Clin J Am Soc Nephrol"},{"key":"R2-26-20230811","doi-asserted-by":"crossref","first-page":"1157","DOI":"10.1046\/j.1523-1755.2003.00242.x","article-title":"Lillian Jean Kaplan International Prize for advancement in the understanding of polycystic kidney disease.
