Urology Flashcards
What are the common symptoms of prostate pathology?
LUTS
hesitancy, frequency, weak flow, nocturia, incomplete emptying, straining, terminal dribbling, urgency
How useful is PSA in assessing prostate pathology?
Unreliable
75% false positives (falsely investigated)
15% false negatives (falsely reassuring)
What causes a raised PSA?
Prostate cancer BPH Prostatitis UTI Vigorous exercise (particularly cycling) Recent ejaculation
How is BPH investigated?
PR exam
Abdo exam (palpable bladder)
Urine chart (input/output for 3 days)
Urine dipstick (infection, haematuria, other pathology)
PSA (for prostate cancer, patient choice)
How is BPH managed?
Medical: tamsulosin + finasteride
(tamsulosin = alpha-blocker, immediate symptom relief from smooth muscle relaxation
side effect = postural hypotension)
(finasteride = reduce size of prostate, longer term therapy - <6months for action)
Surgical = TURP (transurethral resection of prostate) - remove part of prostate from inside urethra
What are the 2 types of prostatitis?
Acute bacterial prostatitis Chronic prostatitis (infective/non-infective)
How does prostatitis present?
Pelvic pain LUTS Sexual dysfunction Painful bowel movements Tender + enlarged prostate on exam
Acute = systemic signs of infection (fever, fatigue, myalgia, nausea, sepsis)
How is prostatitis diagnosed?
PR exam (enlarged + tender)
Abdo exam (distended bladder)
Urine dipstick + culture
STI screen
How is acute vs chronic prostatitis managed?
Acute = Abx (28 days ofloxacin, ciprofloxacin or trimethoprim)
Analgesia/laxatives
Chronic: Tamsulosin (symptom relief), Abx if within 6 months of symptom onset Laxatives/analgesia Psychological therapy (if psychosocial symptoms)
What are the symptoms of prostate cancer?
LUTS (freq, hesitation, weak flow, nocturia)
Haematuria
Erectile dysfunction
Weight loss/bone pain/cauda equina (if advanced/mets)
How is prostate cancer diagnosed?
PSA
PR exam (craggy, hard, asymmetrical, irregular, loss of central sulcus)
Multiparametric MRI (1st line - reported on Likert scale)
Prostate biopsy (transurethral or transperineal)
Isotope bone scan (for bony mets)
What is the Gleason score and what does it indicate?
Grading system for severity or prostate cancer, used to guide treatment
Based upon histology from biopsies (2 numbers added together)
<6 = low risk 7 = intermediate risk >8 = high risk
How is prostate cancer managed?
Surveillance / watchful waiting (if early stage)
External beam radiotherapy (proctitis side effect)
Brachytherapy (radioactive seeds inserted into prostate, continuous targeted radiotherapy to prostate)
Hormone therapy (androgen receptor blocker - Bicalutamide)
Surgery (radical prostatectomy with curative intent)
