Acute urinary retention is a [[medical emergency]] and requires prompt treatment. The pain can be excruciating when urine is not able to flow out. Moreover, one can develop severe [[perspiration|sweating]], [[chest pain]], [[anxiety]] and [[hypertension|high blood pressure]]. Other patients may develop a shock-like condition and may require admission to a hospital. Serious complications of untreated urinary retention include [[urinary bladder|bladder]] damage and chronic [[renal failure|kidney failure]].<ref>{{cite web | url = http://www.retentionurinary.com/ | title = General information on urinary retention | archive-url = https://web.archive.org/web/20100220120543/http://www.retentionurinary.com/ | archive-date = 20 February 2010 | work = Retention Urinary }}</ref> Urinary retention is a disorder treated in a hospital, and the quicker one seeks treatment, the fewer the complications.{{cn|date=April 2021}}
