Benign Prostatic Hyperplasia (BPH) Flashcards
BPH is caused by hyperplasia of the s____ and e___ cells of the prostate (inner transitional zone),which narrows urethra and presents with lower urinary tracts symptoms (LUTS)
stromal and epithelial
What are stromal cells?
connective tissue cells
What are some typical LUTS that occur with prostate pathology?
Hesitancy
Weak flow
Urgency
Frequency
Intermittency
Straining
Terminal dribbling
Incomplete emptying
Nocturia
What is used to assess the severity of LUTS?
International prostate symptom score (IPSS)
What are risk factors for BPH?
Increased age
Family history
Heart disease
Beta-blocker use
Obesity
Diabetes
Erectile dysfunction
What initial assessments are done for men presenting with LUTS?
Abdominal exam to assess palpable bladder
Digital rectal exam to assess size, shape and characteristics of prostate
Urine dipstick (infection, haematuria)
PSA test if patient wants
Urinary frequency-volume chart
What imaging can be done for BPH?
USS
Cystoscopy
What is PSA testing?
Prostate-specific antigen is raised in prostate cancer, BPH, prostatitis, UTIs, vigorous exercises and recent ejaculation or prostate stimulation.
High rate of false positive and some false negatives. may lead to more invasive prostate biopsies.
Needs to be informed decision.
What medications can be given to patients with symptoms?
Alpha blockers eg Tamsulosin (relax smooth muscle ie bladder neck)
5-alpha reductase inhibitors eg finasteride (gradually reduce size of protate)
How do 5-alpha reductase inhibitors work?
The enzyme 5-alpha reductase, converts testosterone to dihydrotestosterone (DHT) which is more potent. Inhibiting this conversion leads to reduction in prostate size.
Takes up to 6 months treatment for effects.
What are surgical options for BPH?
TURP (transurethral resection of prostate)
TUVP (transurethral electro-vaporisation of prostate
HoLEP (holmium laser enucleation of prostate)
Open prostatectomy (via abdominal or perineal incision)
What is a complication of TURP?
Retrograde ejaculation (semen goes wrong way, up into bladder rather than down urethra)
What are complications of BPH?
Bladder hypertrophy
Urinary retention
UTIs (residual urine)
Hydronephrosis
