Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'нефрит' (nephritis), which is kidney inflammation.
- The Russian direct equivalent is 'гидронефроз'. Ensure correct transliteration from Latin/Greek roots.
Common Mistakes
- Misspelling as 'hydronefrosis' (dropping the 'ph').
- Incorrectly using it to refer to any kind of kidney failure or infection.
- Mispronouncing the stress pattern (stress is on the 'fro' syllable).

FAQ
Frequently Asked Questions
No. Hydronephrosis is a structural problem involving fluid buildup from a blockage. An infection (like pyelonephritis) is caused by bacteria, though an obstruction can predispose to infection.
Often, yes. Treatment focuses on removing the cause of the obstruction (e.g., a stone, stricture, or enlarged prostate). If treated promptly, kidney function can recover.
It can be, especially if it develops acutely (suddenly). Dull or sharp flank pain is common. Chronic hydronephrosis may sometimes be painless.
Primarily through imaging studies such as ultrasound, CT scan, or MRI urogram, which visually show the dilated kidney and often identify the site of obstruction.
