Additional data, including maximum uroflow (<jats:italic>Q<\/jats:italic><jats:sub>max<\/jats:sub>) and postvoid residual urine (PVR), were obtained from the electronic medical record (EMR). The cohort was divided into three groups: normal, oliguria, and polyuria based on their 24\u2010hour voided volume (24HVV). The LUTSS, 24HVV, maximum voided volume (MVV), maximum flow rate (<jats:italic>Q<\/jats:italic><jats:sub>max<\/jats:sub>), and PVR\u00a0were compared between those with oliguria and polyuria.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 327 men (mean age 62, SD: 19) completed the LUTSS questionnaire and contemporaneous 24HBD. Of these, 61% had a normal 24HVV, 13% had oliguria, and 26% had polyuria. A total of 147 patients from the study cohort had contemporaneous <jats:italic>Q<\/jats:italic><jats:sub>max<\/jats:sub> and PVR abstracted from the EMR. There was no difference in symptom severity, bother, or PVR among the three patient groups. However, several objective metrics were significantly correlated with urine output. Men with oliguria, as compared to men with polyuria were older (65 vs. 55\u00a0years) and had lower MVV (260\u00a0vs.\u00a0470\u2009mL), fewer voids\/24\u2009h (8 vs. 13),\u00a0and lower <jats:italic>Q<\/jats:italic><jats:sub>max<\/jats:sub> (8.5\u00a0vs. 18.3\u2009mL\/s).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>These observations suggest that men with oliguria or polyuria and LUTS constitute easily distinguished phenotypes that might require different diagnostic and therapeutic algorithms. Those with oliguria were older, and had lower MVVs and much lower uroflows, suggesting that they are more likely to have underlying disorders such as bladder outlet obstruction and detrusor underactivity or may be patients with overactive bladder who reduced fluid intake to improve symptoms.<\/jats:p><\/jats:sec>","DOI":"10.1002\/nau.25164","type":"journal-article","created":{"date-parts":[[2023,2,24]],"date-time":"2023-02-24T08:23:44Z","timestamp":1677227024000},"page":"718-724","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["The
