Management of Benign Prostatic Hyperplasia

Initial Management

Watchful waiting is the preferred management strategy for patients with mild symptoms and should be considered for those with moderate to severe symptoms who have not developed complications 1, 2, 3
During watchful waiting, patients should be monitored yearly with repeat evaluations 3
Simple lifestyle modifications can reduce symptom distress, including decreasing fluid intake at bedtime 2 and reducing caffeine and alcohol consumption 2

Alpha-blockers work by inhibiting alpha1-adrenergic-mediated contraction of prostatic smooth muscle, relieving bladder outlet obstruction 3
Recommended alpha-blockers include alfuzosin 2, doxazosin 2, and terazosin 2
These agents produce on average a 4-6 point improvement in AUA Symptom Index, which patients perceive as meaningful 2
Key differences between alpha-blockers: tamsulosin has a lower risk of orthostatic hypotension but a higher risk of ejaculatory dysfunction 3

Surgical intervention is appropriate for patients with moderate-to-severe LUTS who have failed medical therapy 5
TURP remains the benchmark for surgical therapies due to published evidence of efficacy from randomized clinical trials with long-term follow-up 5
Complications of TURP include sexual dysfunction 6, bladder neck contracture 6, need for blood transfusion 6, UTI 5, and hematuria 5

Transurethral Microwave Thermotherapy (TUMT) is a minimally invasive option 4
Transurethral Needle Ablation (TUNA) appears to be more effective than medical therapy but less effective than TURP 6

Prostatic stents should be considered only in high-risk patients, especially those with urinary retention 5
Prostatic stents are associated with significant complications such as encrustation, infection, and chronic pain 5

Prostate volume assessment helps predict natural history and response to therapy 3
Patients on alpha-blockers should be monitored for orthostatic hypotension, especially with first dose 2
Surgical decisions should consider the patient's prostate size, comorbidities, and surgeon's experience 5
Combination therapy with finasteride and doxazosin may have more adverse effects, including asthenia 4 and postural hypotension 1
