Asymptomatic UTI in pregnancy, true is:a) Most are usually asymptomatic in pregnancyb) If untreated, progresses to pyelonephritisc) Early and prompt treatment prevents abnormalities in fetusd) Increase chance of premature infante) Increase risk of chronic renal lesion

**Core Concept**
Asymptomatic urinary tract infections (UTIs) in pregnancy pose a risk to both maternal and fetal health. The pathophysiology involves bacterial colonization of the urinary tract, often in the setting of pregnancy-induced urinary stasis and hormonal changes.

**Why the Correct Answer is Right**
Asymptomatic UTIs in pregnancy are common due to the physiological changes that occur during pregnancy. The risk of progression to pyelonephritis is higher in pregnant women due to the increased susceptibility of the urinary tract to infection. However, prompt and early treatment can prevent complications and reduce the risk of fetal abnormalities. Asymptomatic UTIs are often undiagnosed, but they can have serious consequences, including premature birth and low birth weight.

**Why Each Wrong Option is Incorrect**
**Option A:** This statement is misleading, as most UTIs in pregnancy are symptomatic, and the presence of symptoms should prompt further investigation and treatment.
**Option B:** While pyelonephritis is a potential complication of untreated UTI in pregnancy, it is not the most common outcome.
**Option D:** While premature birth is a potential consequence of untreated UTI in pregnancy, it is not the most directly related option.
**Option E:** Chronic renal lesions are a potential long-term consequence of untreated UTI in pregnancy, but it is not the most directly related option.

**Clinical Pearl / High-Yield Fact**
Asymptomatic UTIs in pregnancy require prompt and early treatment to prevent complications and ensure fetal health.

**Correct Answer: C. Early and prompt treatment prevents abnormalities in fetus**
