The word "Protureter" is a rare and complex term used in the field of urology. The correct spelling of the word is pronounced as /proh-cher-uh-ter/. The first syllable 'proh' is pronounced with a prolonged 'o' and the 'ch' sound in the second syllable comes from the letter 't'. The 'uh' sound is present in both the third and fourth syllables which are pronounced together quickly. Lastly, the final syllable 'ter' sounds like 'tur' with a slight emphasis on the 'r'. Overall, it's a difficult word to pronounce and spell precisely.
