## 문제

A 45-year-old male client presents to the emergency department with complaints of urinary frequency, urgency, and pelvic pain. The nurse suspects acute bacterial prostatitis. Which assessment finding would be most characteristic of this condition?

## 보기

1. Fever, chills, and tender prostate on digital rectal examination **✔ 정답**
2. Painless hematuria with no other symptoms noted
3. Gradual onset of nocturia over several months
4. Intermittent claudication and leg pain on walking

**정답: 1**

## 해설

Acute bacterial prostatitis typically presents with systemic symptoms like fever and chills, along with a tender prostate on digital rectal exam. Other options describe findings not characteristic of acute prostatitis.

Understanding Acute Bacterial Prostatitis (ABP)

This question tests your ability to differentiate the clinical presentation of acute bacterial prostatitis from other urological or vascular conditions. ABP is classified as a complicated urinary tract infection (UTI) that requires prompt recognition and appropriate antibiotic therapy to prevent progression to severe complications such as urosepsis or prostatic abscess formation [3,4].

Why Option 1 is Correct

The combination of fever, chills, and a tender prostate on digital rectal examination (DRE) represents the hallmark presentation of acute bacterial prostatitis. The underlying pathophysiology involves an ascending bacterial infection, most commonly gram-negative organisms like Escherichia coli, leading to acute inflammation and edema of the prostate gland [1,2]. This inflammatory process triggers systemic symptoms (fever and chills) due to the release of pyrogens, while the localized infection makes the gland exquisitely tender upon palpation. The clinical presentation often includes non-specific lower urinary tract symptoms such as urinary frequency, urgency, and pelvic pain, which align with the client's initial complaints [1].

Why the Other Options are Incorrect

- Option 2 (Painless hematuria): This presentation is more characteristic of bladder cancer or other structural abnormalities within the urinary tract, not an acute infectious process. ABP involves significant inflammation, which typically produces painful, not painless, symptoms. While hematuria can occur with severe UTIs, the absence of pain and systemic signs makes this an unlikely fit for ABP.

- Option 3 (Gradual onset of nocturia over several months): This describes a chronic, progressive condition such as benign prostatic hyperplasia (BPH) or chronic prostatitis. ABP is an acute condition with a sudden onset of severe symptoms, not a gradual development over months [3].

- Option 4 (Intermittent claudication and leg pain on walking): This is a classic vascular finding associated with peripheral arterial disease (PAD). It results from arterial insufficiency to the lower extremities during exertion and is unrelated to the genitourinary infection seen in ABP.

Clinical Significance and Complications

Recognizing the characteristic findings of ABP is critical because a delayed or missed diagnosis can lead to serious complications. As the infection progresses, it can form a prostatic abscess, a rare but serious urological emergency occurring in approximately 0.5% of urologic conditions [1]. Risk factors for abscess formation include diabetes mellitus and immunosuppression, though it can occur in previously healthy individuals [2,4]. An abscess may present atypically, with multiloculation and extension beyond the prostate into areas like the ischiorectal fossa, making diagnosis challenging and increasing the risk of urosepsis and multi-organ failure [4]. Imaging plays a crucial role in confirming the diagnosis when an abscess is suspected [1].References (research sources)

## 임상 시나리오

Recognizing Acute Bacterial ProstatitisKey Assessment Findings for Prompt Intervention
Suspect acute bacterial prostatitis in a male with sudden onset of urinary frequency, urgency, and pelvic pain. The hallmark is the combination of systemic symptoms (fever, chills) and a tender, boggy prostate on digital rectal examination.

CautionAvoid vigorous prostate massage during DRE as it can precipitate bacteremia and sepsis. A gentle exam is critical to confirm tenderness without causing harm.

## 핵심 개념

- **Acute Bacterial Prostatitis (ABP)** — A severe, sudden-onset bacterial infection of the prostate gland causing systemic and local symptoms, classified as a complicated UTI.
- **Digital Rectal Examination (DRE)** — A physical exam procedure where a clinician palpates the prostate through the rectal wall to assess size, tenderness, and texture.
- **Hallmark Signs** — The characteristic clinical features most commonly associated with a specific disease, such as fever, chills, and tender prostate in ABP.
- **Pyrogens** — Substances, typically produced by bacteria or the body's immune response, that cause fever by acting on the hypothalamus.
- **Urosepsis** — A life-threatening systemic infection originating from the urinary tract that can lead to organ dysfunction and septic shock.
