Urotoxy is a made-up word, but it can be spelled using the International Phonetic Alphabet (IPA). The first two syllables are pronounced "yur-uh," with a short "uh" sound in the first syllable and a schwa in the second. The final syllable is pronounced "tok-see," with a long "o" sound and a soft "k." The word lacks a clear meaning or context, but exploring the spelling using IPA can be helpful in understanding pronunciation and phonetics for other words.
