**Question:** 60 yr old male undergoes TURP. After 3 days patient develops altered sensitiveness and drowsiness. Most probable diagnosis is

A. Brain abscess
B. Encephalopathy
C. Urinary retention
D. Post-operative complications

**Core Concept:**

TURP (Transurethral Resection of Prostate) is a surgical procedure commonly used to treat Benign Prostatic Hyperplasia (BPH), where the prostate gland is removed or reduced in size to improve urinary flow. Post-operative complications are possible, including neurological issues. Encephalopathy refers to brain dysfunction due to impaired brain function or reduced brain activity, which may be caused by various factors.

**Why the Correct Answer is Right:**

The correct answer is "B. Encephalopathy" because the patient's altered sensitiveness and drowsiness are indicative of impaired brain function or reduced brain activity. Following a TURP procedure, these symptoms could arise due to a complication known as encephalopathy. Encephalopathy is a common complication following TURP, particularly in elderly patients like the one described.

**Why Each Wrong Option is Incorrect:**

A. Brain abscess is a localized infection in the brain, usually caused by bacteria or fungi. While it can present with similar symptoms, the correct answer is "encephalopathy" because brain abscess is a specific condition, whereas encephalopathy is a broader term encompassing various causes of brain dysfunction.

B. While urinary retention can lead to neurological complications, the symptoms described in the question (altered sensitiveness and drowsiness) are more consistent with encephalopathy, which is a broader term for brain dysfunction.

C. Urinary retention is a consequence of the TURP procedure, not a cause of altered sensitiveness and drowsiness. Encephalopathy is the most suitable answer due to its association with impaired brain function.

**Clinical Pearl:**

Understanding the risk factors for encephalopathy after TURP is crucial for healthcare professionals, particularly in elderly patients. Risk factors include advanced age, pre-existing neurological conditions, and prolonged anesthesia duration. Monitoring patients for symptoms like altered mental status and prescribing appropriate interventions, such as adequate pain management, can help reduce the risk of encephalopathy and improve patient outcomes.
