Cheat Sheet
- Definition of Nephrectasis -
Nephrectasis describes the distension of the kidney's collecting system due to urine backflow, highlighting "nephr - " (kidney) and " - ectasis" (expansion) (Merck Manual). This term clarifies that the distension of the kidney is called nephrectasis, distinct from simple swelling.
- Common Obstructive Causes -
Ureteral stones, strictures, and benign prostatic hyperplasia frequently trigger nephrectasis by blocking urine outflow (American Urological Association). Early identification of these etiologies is vital to prevent irreversible renal damage.
- Diagnostic Imaging Strategies -
Renal ultrasound is the first-line tool for detecting dilation of the collecting system, with high sensitivity for early nephrectasis (American Institute of Ultrasound in Medicine). When ultrasound findings are inconclusive, CT urography offers detailed anatomical resolution.
- Medical Term for Scanty Urination -
Scanty urination, the medical term scanty urination is "oliguria," defined as a condition of scanty urine production below 400 mL per 24 hours (National Kidney Foundation). Oliguria signals compromised renal perfusion or injury and warrants prompt evaluation.
- Mnemonic for Urine Output Disorders -
Remember "AnOliPo" to differentiate Anuria (≤50 mL), Oliguria (<400 mL), and Polyuria (>2,500 mL) in 24 hours (UpToDate). This quick mnemonic helps you recall a condition of scanty urine production and plan appropriate management.
