Clinical Case Studies and Examination Preparation

This chapter presents a series of clinical case scenarios and multiple-choice questions designed to test the reader's understanding of the diagnosis and management of benign prostatic hyperplasia. These cases and questions are formatted to be similar to those encountered in professional examinations, such as the FRCSEd(Urol).

Clinical Case Scenarios

Case 1:

A 68-year-old male presents with a 2-year history of worsening lower urinary tract symptoms. His IPSS is 22, and his quality of life score is 5 ("unhappy"). He has a history of hypertension, which is well-controlled on a beta-blocker. His PSA is 3.5 ng/mL, and his prostate volume on transrectal ultrasound is 90 mL. He has failed a trial of combination therapy with tamsulosin and dutasteride due to side effects of dizziness and decreased libido.

Discussion Questions:

1. What are the surgical options for this patient?
2. Given his large prostate volume, which procedures would be most appropriate?
3. What are the potential risks and benefits of each of these procedures?
4. How would you counsel this patient regarding his treatment options?

Case 2:

A 55-year-old male presents with bothersome LUTS and a desire to preserve ejaculatory function. His IPSS is 15. His prostate volume is 40 mL, and his PSA is 1.8 ng/mL. He is not keen on long-term medical therapy.

Discussion Questions:

1. What are the most suitable treatment options for this patient?
2. Discuss the role of Minimally Invasive Surgical Therapies (MIST) in this scenario.
3. What are the advantages and disadvantages of Prostatic Urethral Lift (UroLift) and Convective Water Vapor Thermal Therapy (Rezum) for this patient?

Mock Examination Questions (Multiple Choice)

1. Which of the following is the primary site of origin for benign prostatic hyperplasia? a) Peripheral zone b) Central zone c) Transition zone d) Anterior fibromuscular stroma

2. A 72-year-old male presents with acute urinary retention. His prostate is enlarged on DRE. What is the most appropriate initial management? a) Start an alpha-blocker immediately b) Perform a cystoscopy c) Insert a urethral or suprapubic catheter d) Schedule for urgent TURP

3. Which of the following surgical procedures for BPH is considered "size-independent"? a) GreenLight Laser PVP b) Transurethral Resection of the Prostate (TURP) c) Holmium Laser Enucleation of the Prostate (HoLEP) d) Prostatic Urethral Lift (UroLift)

4. What is the mechanism of action of 5-alpha reductase inhibitors (5-ARIs) in the treatment of BPH? a) Relaxation of prostatic smooth muscle b) Inhibition of the conversion of testosterone to DHT c) Ablation of prostatic tissue d) Blockade of alpha-1 adrenergic receptors

5. A patient undergoing monopolar TURP develops confusion, nausea, and a seizure. What is the most likely diagnosis? a) Septic shock b) Myocardial infarction c) TUR syndrome d) Cerebrovascular accident

Answers: 1(c), 2(c), 3(c), 4(b), 5(c)
