The spelling of the word "hysterical urine" may seem strange at first glance. The word "hysterical" is pronounced /hɪˈstɛrɪkəl/ and means extreme or uncontrollable emotions, while "urine" is pronounced /jʊərɪn/ and refers to the liquid waste product of the human body. Together, "hysterical urine" may refer to urine expelled due to a fit of hysteria. The word's spelling reflects its origin as a medical term used in the past to describe certain symptoms of hysteria, a condition now considered outdated and controversial.
Pale urine of low specific gravity, passed in large amount during an hysterical attack.

"Hysterical urine" is not a term with a widely recognized etymology. It is possible that you may be referring to the term "hysterical incontinence" or "hysterical urinary retention", which are medical terms used to describe certain conditions related to urinary dysfunction. In these cases, "hysterical" does not carry its conventional meaning of excessive emotion or irrational behavior, but rather refers to symptoms or phenomena that are difficult to explain or understand. However, if you have a different specific term in mind, please correct me so that I can provide accurate information.
