## **Core Concept**
The resting ureteric pressure refers to the baseline pressure within the ureters when they are not actively contracting. This pressure is essential for understanding ureteral function and its role in urine transport from the kidneys to the bladder.

## **Why the Correct Answer is Right**
The correct answer, , indicates that the resting ureteric pressure is approximately 5-10 cm of water. This low pressure is crucial for the ureters' peristaltic movements, which help propel urine down to the bladder. The pressure is generated by the smooth muscle in the ureteral walls and is influenced by the ureter's muscular structure and its innervation.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This pressure is too high for resting ureteric pressure. Resting pressures are typically much lower.
- **Option B:** This option might seem plausible but is not the correct range for resting ureteric pressure.
- **Option D:** This pressure seems too low and not reflective of the actual resting pressure within the ureters.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that ureteral peristalsis and pressure play a critical role in preventing vesicoureteral reflux. Abnormalities in ureteral pressure or peristalsis can lead to conditions such as ureteral obstruction or reflux, which are significant in clinical urology.

## **Correct Answer:** . 10-20 cm of water
