## 문제

A 68-year-old male client with benign prostatic hyperplasia (BPH) is being assessed by the nurse. Which assessment finding would be most concerning and require immediate nursing intervention?

## 보기

1. Reports of needing to urinate often and urgently throughout the day
2. Urinary stream that is weak and stops and starts during voiding
3. Waking up three to four times each night to urinate
4. Total inability to pass urine for eight hours with persistent urge **✔ 정답**

**정답: 4**

## 해설

Complete urinary retention is a urological emergency requiring immediate intervention to prevent bladder or kidney damage. Inability to void for 8 hours with urge is the most concerning finding. Other options are typical BPH symptoms but not emergencies.

Correct Answer: 4. Total inability to pass urine for eight hours with persistent urge

Clinical Priority and Pathophysiology

This question tests your ability to recognize a urological emergency in a client with benign prostatic hyperplasia (BPH). The most concerning finding is a total inability to pass urine for eight hours accompanied by a persistent urge to void. This clinical picture defines acute urinary retention (AUR), a condition where the bladder is pathologically full but the client cannot initiate micturition. In the context of BPH, the prostate gland enlarges and compresses the prostatic urethra, increasing urethral resistance. When the detrusor muscle can no longer overcome this obstruction, urine output ceases entirely, leading to a rapid accumulation of urine and painful bladder distension.

The source material explicitly identifies "urinary retention due to Benign Prostatic Hyperplasia (BPH)" as a "frequent and serious urological emergency" [1]. This is not merely a progression of lower urinary tract symptoms (LUTS) but a critical failure of the bladder's emptying mechanism. If left untreated, the sustained high intravesical pressure can be transmitted backward to the kidneys, causing post-renal acute kidney injury. Furthermore, the stagnant urine serves as a medium for bacterial growth, increasing the risk of a urinary tract infection. Immediate nursing intervention, which involves notifying the healthcare provider and preparing for immediate bladder decompression via catheterization, is required to relieve the obstruction, prevent bladder wall damage, and preserve renal function.

Analysis of Incorrect Options

The other options describe classic storage and voiding symptoms of BPH, which are chronic and non-emergent, though they do affect quality of life.

- Option 1 (Reports of needing to urinate often and urgently throughout the day): This describes urinary frequency and urgency. These storage symptoms result from the bladder's response to chronic outlet obstruction; the detrusor muscle becomes overactive and irritable. While distressing, this does not represent an immediate threat to organ function and is managed through scheduled voiding, medication, and lifestyle changes.

- Option 2 (Urinary stream that is weak and stops and starts during voiding): This is a classic description of intermittency and a weak stream, which are hallmark voiding symptoms of BPH. The enlarged prostate obstructs the flow of urine, causing a reduced caliber and force of the stream. The "stops and starts" pattern indicates the detrusor muscle is struggling to maintain sufficient pressure to complete the void. This is a chronic symptom of obstruction, not an acute emergency.

- Option 3 (Waking up three to four times each night to urinate): This is the definition of nocturia. In BPH, the bladder does not empty completely, leading to a reduced functional capacity and the need to void more frequently to empty the residual volume. While nocturia can significantly disrupt sleep and increase the risk of falls in older adults, it is a chronic, non-emergent symptom.

Nursing Clinical Reasoning

Your clinical reasoning must differentiate between the chronic, progressive symptoms of bladder outlet obstruction and the acute, decompensated state of complete obstruction. The key discriminator in option 4 is the word "total." A client with BPH may have a high post-void residual (PVR) volume and still be able to pass some urine. When the ability to pass any urine is lost for an extended period (8 hours) with a persistent, painful urge, the compensatory mechanisms of the detrusor muscle have failed. This transition from chronic partial obstruction to acute complete obstruction constitutes the emergency. The study referenced in the source material investigates a stent designed for precisely this scenario—either to manage an acute retention episode or to serve as a bridge for patients awaiting definitive surgery—reinforcing that this finding demands immediate intervention beyond routine BPH management [1].References (research sources)

## 임상 시나리오

Acute Urinary Retention in BPHRecognizing a Urologic Emergency
A total inability to void for 6-8 hours with a persistent, painful urge defines acute urinary retention (AUR). This is a failure of the detrusor muscle to overcome prostatic obstruction.

Immediate intervention is required to prevent complications like post-renal acute kidney injury and bladder wall damage. Prepare for prompt bladder decompression via urethral catheterization.

CautionDo not mistake AUR for common BPH symptoms like nocturia or weak stream. A palpable, distended bladder with suprapubic pain confirms the emergency. Avoid administering diuretics or forcing fluids.

## 핵심 개념

- **Acute Urinary Retention (AUR)** — A sudden, painful inability to void despite a full bladder, often caused by prostatic obstruction in BPH, requiring emergency catheterization.
- **Benign Prostatic Hyperplasia (BPH)** — Non-cancerous enlargement of the prostate gland that compresses the urethra, leading to obstructive and irritative lower urinary tract symptoms.
- **Detrusor Muscle** — The smooth muscle of the bladder wall whose contraction facilitates voiding; it can decompensate against chronic obstruction.
- **Post-renal Acute Kidney Injury** — Kidney damage resulting from obstruction of urine flow downstream from the kidneys, a potential complication of untreated urinary retention.
