Which term means distention of a ureter?
ureterectasis
ureterostenosis
The correct answer and explanation is :
The correct term for the distention of a ureter is ureterectasis.
Explanation:
Ureterectasis is derived from the Greek words “ureter” (the tube that connects the kidney to the bladder) and “ectasis” (meaning stretching or dilation). It refers to the abnormal enlargement or dilatation of the ureter, which can result from various conditions that lead to an obstruction or hindrance of urine flow. This can occur due to conditions such as kidney stones, tumors, or strictures that prevent the normal passage of urine from the kidney to the bladder. Ureterectasis is typically diagnosed with imaging techniques, such as an ultrasound or CT scan, which reveal the abnormal enlargement of the ureter.
Ureterostenosis:
On the other hand, ureterostenosis refers to the narrowing (stenosis) of the ureter, which can occur due to scar tissue, congenital abnormalities, or other causes that restrict the flow of urine. While ureterostenosis results in the constriction or narrowing of the ureter, it contrasts with ureterectasis, which specifically refers to its distention or dilation. Therefore, ureterostenosis is associated with obstruction or a reduced lumen of the ureter, potentially leading to hydronephrosis, a condition where the kidney swells due to urine buildup.
Causes and Consequences of Ureterectasis:
Ureterectasis often results from an obstruction that impedes the normal outflow of urine, causing the ureter to stretch and expand. Common causes include:
- Kidney Stones: Stones can block the ureter, leading to distention.
- Tumors: A growth in or around the ureter may obstruct urine flow.
- Strictures: Scarring from prior surgeries or injuries can narrow the ureter.
- Congenital Abnormalities: Some people are born with abnormal ureter shapes or sizes, which may predispose them to distention.
This condition, if left untreated, can lead to kidney damage or infections, making prompt diagnosis and treatment essential.
