Which of the following is not a component of triad of Wilm’s tumour is
**Core Concept**
Wilm's tumor, also known as nephroblastoma, is a type of cancer that affects the kidneys, primarily in children. The triad of Wilm's tumor typically consists of abdominal pain, a palpable abdominal mass, and hematuria, which are the classic symptoms and signs that prompt further investigation and diagnosis.
**Why the Correct Answer is Right**
The triad of Wilm's tumor is a well-established clinical entity, and identifying its components is crucial for accurate diagnosis. The presence of an abdominal mass is usually the first indication of Wilm's tumor, followed by symptoms such as abdominal pain and hematuria. Hematuria is the presence of blood in the urine, which can be microscopic or gross.
**Why Each Wrong Option is Incorrect**
**Option A:** Anemia is not a classic component of the triad of Wilm's tumor. While anemia may be present in some patients, it is not a defining feature of the disease.
**Option B:** Hypertension is not a component of the triad of Wilm's tumor, but it can be a complication of the disease due to renal involvement.
**Option C:** Nephrotic syndrome is not a component of the triad of Wilm's tumor. However, patients with Wilm's tumor may present with proteinuria, which can be a sign of renal involvement.
**Clinical Pearl / High-Yield Fact**
The triad of Wilm's tumor is a classic example of a clinical entity that is remembered by the mnemonic "PAIN" (Pain, Abdominal mass, and Incontinence or Hematuria). This mnemonic can help students recall the key components of the triad and differentiate Wilm's tumor from other abdominal masses.
**Correct Answer: D.**
