When was the first book detailing the characteristics of urine written?

Observing urine closely became a foundational diagnostic habit in ancient medicine, but it wasn’t until the medieval Islamic world that a dedicated, systematic book on urine characteristics appeared. Around 900 CE, a prominent physician organized and codified observations about urine—its color, clarity, odor, taste, and sediment—and linked these traits to various diseases. This work represents the first focused, written reference that treated urine analysis as a coherent diagnostic tool, setting the stage for how physicians would use urinalysis for centuries. That’s why the date around 900 AD is the best fit among the options: it marks the emergence of a formal, book-length treatment of urine’s properties, rather than earlier scattered notes or much later compilations.
