Disorders of the Male Reproductive System

491
Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.
Prostate disorders are another major concern. These conditions can impair urinary flow due to the prostate's location around the urethra....

Anatomy of the Genitourinary System II: Bladder and Urethra

155
The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...

Summary

Prostatic urethral length (PUL) is a key predictor for benign prostatic hyperplasia (BPH) surgery. Longer PUL in BPH patients indicates a higher likelihood of needing surgical intervention.

Area of Science:

  • Urology
  • Medical Imaging

Background:

  • Benign prostatic hyperplasia (BPH) involves changes in prostate structure, including prostatic urethral length (PUL).
  • Predicting the need for surgical intervention in BPH is crucial for patient management.

Purpose of the Study:

  • To evaluate if prostatic urethral length (PUL) can predict the necessity of surgery in patients diagnosed with benign prostatic hyperplasia (BPH).

Main Methods:

  • A prospective observational study over 12 months included 153 patients with lower urinary tract symptoms due to BPH.
  • Evaluations included International Prostate Severity Score, PSA, and Transrectal Ultrasound (TRUS) to measure PUL, prostate volume, intravesical prostatic protrusion, and post-void residual urine.
  • Logistic regression identified risk factors for surgery in patients unresponsive to medical treatment or with complications.

Main Results:

  • Eighty-three (54.2%) patients underwent surgery.
  • Surgical patients had significantly higher prostate volume, intravesical prostatic protrusion, post-void residual volume, PSA, and PUL.
  • Mean PUL was 39.47 mm in the surgical group vs. 26.20 mm in the non-surgical group (p <0.0001).
  • ROC analysis showed an area under the curve of 0.866 for PUL, with a cutoff of 31.5 mm (81% sensitivity, 84.3% specificity).

Conclusions:

  • Longer prostatic urethral length (PUL) in BPH patients may indicate a need for surgical management.
  • PUL measurement via Transrectal Ultrasound (TRUS) shows potential as a predictive factor for BPH surgery.
  • This finding aids in surgical decision-making for benign prostatic hyperplasia.
