Understanding Benign Prostatic Hyperplasia (BPH)

This process follows a specific pathological progression:

1. Urethral Compression: The growing nodules squeeze the urethra.
2. Urinary Obstruction: The compression creates a physical blockage, making it difficult for urine to flow freely.
3. Incomplete Bladder Emptying: Because the flow is obstructed, the bladder cannot empty itself fully during urination.

Exam Tip: When distinguishing BPH from prostate cancer, remember the location. BPH involves hyperplasia in the center of the gland causing obstruction, whereas cancer often starts in the periphery and may not cause obstruction until it is advanced.

Clinical Symptoms and Complications

The symptoms of BPH are largely a direct result of the urinary obstruction and the bladder's attempt to compensate for the blockage.

Early Signs and Urinary Symptoms

Patients often present with "lower urinary tract symptoms" (LUTS), which include:

• Hesitancy: Difficulty initiating the stream of urine.
• Decreased Force: A weak or slow urine stream.
• Dribbling: Inability to maintain a steady stream.
• Frequency and Nocturia: The need to urinate more often, including waking up frequently at night to urinate (nocturia).

Progressive Complications

If the obstruction is not managed, the condition can escalate from a localized prostate issue to a systemic renal problem.

1. Cystitis: Incomplete emptying of the bladder creates a stagnant pool of urine, which serves as a breeding ground for bacteria, leading to bladder infections known as cystitis.
2. Hydronephrosis and Pyelonephritis: Continued obstruction can cause the bladder to become distended. This pressure can back up into the ureters, causing them to dilate. The infection or pressure can then ascend to the kidneys, leading to pyelonephritis (kidney infection) and potential permanent kidney damage.

Diagnosis and Treatment

To diagnose BPH, a clinician may perform a digital rectal exam, which can reveal an enlarged prostate gland.

When the symptoms become significant or the obstruction is severe, medical intervention is required. One of the most common surgical treatments for BPH is:

Transurethral Resection of the Prostate (TURP).

This procedure involves removing the obstructing prostatic tissue through the urethra to restore normal urine flow and alleviate the pressure on the bladder and kidneys.
