Morphology

hydronephrosis = nephrosis (opaque) = hydro + nephr + osis

Although the term is built from classical medical elements meaning roughly 'fluid' + 'kidney condition', the full meaning is highly specialized and not easily inferable for an average learner.

Etymology

Hydronephrosis breaks into parts: hydro- 'water', nephro- 'kidney', and -osis 'condition', and hydro- is the same start you see in hydrate. So hydronephrosis literally means a 'water' condition of the kidney, which helps you remember that urine builds up and makes the kidney swell.
