## 문제

A nurse is assessing a 72-year-old client who was recently diagnosed with renal cell carcinoma. Which assessment finding would be most characteristic of this condition?

What is the most common presenting symptom of renal cell carcinoma that the nurse should assess for?

## 보기

1. Severe flank pain radiating to the groin
2. Frequent urination with burning sensation
3. Painless gross hematuria **✔ 정답**
4. Oliguria with peripheral edema

**정답: 3**

## 해설

Painless gross hematuria is the most characteristic symptom of renal cell carcinoma, seen in 40-60% of cases. Other symptoms like severe pain or oliguria are less common or indicate other conditions.

Clinical Judgment
This question assesses the Core Concept of identifying the most common and characteristic early symptom of Renal Cell Carcinoma (RCC). The key lies in the characteristic of being "painless." While kidney stones cause severe pain, renal cell carcinoma is painless unless the tumor obstructs the ureter or stretches the renal capsule. Therefore, if you notice sudden red or cola-colored urine without pain, you should immediately suspect renal cell carcinoma. This is also a major reason for delayed diagnosis.

Memory Tip:
The classic triad of renal cell carcinoma symptoms is **H**ematuria, **P**ain, and **M**ass. A mnemonic to remember this is "**H**e **P**unched **M**e." However, the presence of all three is rare, and among them, **painless hematuria** is the most common initial symptom.

KR vs US:
Education on the main symptoms of renal cell carcinoma is the same in both Korea and the US. However, the US NGN exam tends to emphasize 'Critical Cues' requiring immediate reporting, such as Notify HCP!. Painless hematuria is a significant finding that should be reported to a physician immediately.

Clinical Practice Guide
When assessing patients with renal cell carcinoma, you must thoroughly evaluate the characteristics of hematuria (onset, frequency, accompanying symptoms), risk factors (smoking, obesity, family history), and systemic symptoms (fever of unknown origin, weight loss, anemia).
Caution:
In SATA (Select All That Apply) questions asking "Which of the following are symptoms of renal cell carcinoma?", painless hematuria, flank pain, abdominal mass, fever, weight loss, and hypertension can all be correct answers. However, in single-choice questions asking about the "most common initial symptom" or "most characteristic symptom", you must select **painless hematuria**.

## 핵심 개념

- **Renal Cell Carcinoma** — The most common primary kidney cancer arising from the renal parenchyma. Clear cell carcinoma is the most common subtype.
- **Painless Gross Hematuria** — Painless, visible blood in the urine. It is the most common early symptom of renal cell carcinoma and occurs when the tumor invades the renal pelvis or ureter.
- **Flank Pain** — Flank pain. It is one of the three major symptoms of renal cell carcinoma, but it appears when the tumor grows larger or when a blood clot from bleeding obstructs the ureter, rather than in the early stages.
- **Intravenous Pyelogram** — X-ray imaging of the kidneys, ureters, and bladder after injecting contrast dye into a vein. It was used in the past to evaluate hematuria, but is now increasingly being replaced by CT urography.
- **Paraneoplastic Syndrome** — Systemic syndromes caused by substances secreted by the tumor, not by direct invasion of the tumor itself. In renal cell carcinoma, hypertension, hypercalcemia, and polycythemia may occur.
