GU Flashcards
UTI, BPH, prostate cancer, CKD, renal transplant, nephritis, nephrotic syndrome, breast cancer
BPH presentation, examination , Ix
PRESENTATION
- Voiding: poor stream/flow, hesitancy,
incomplete emptying, intermittency
- Storage: nocturia, freq, dribbling, overflow incontinence, haematuria, bladder stones,UTI
EXAMINATION
DRE – smooth, enlarged, symmetrical
Distended bladder if in retention
INVESTIGATIONS
Blood
- PSA
- Cr, U&E
MSU
International prostate symptom score (IPSS)
Imaging
- abdominal USS: Large residual volume,hydronephrosis
- transrectal USS
Voiding Studies
- to suggest if stricture/obstruction picture
Biopsy – trans-rectal biopsy (Gleason score) – to rule out malignancy if high suspicion
Management of BPH + risks - lifestyle, medications, surgery
Lifestyle
- Avoid caffeine/alcohol (reduces urgency/nocturia)
- physio; relaxation w voids, distraction methods to control urgency, bladder
retraining
Medications (IPSS 8-10)
o a-blockers; Doxazosin, Tamsulosin
Smooth muscle relaxation
50-70% respond
SE: drowsy, dizzy, dry mouth, hypotension, ejaculation issues
o 5a-reducatase Inhibitors;
Finasteride
blocks conversion DHT to Testosterone
prevents haematuria,
minimal effects on size
Takes over 6 months to work. Excreted in semencondoms!
SE: impotence, decr libido
Surgery (IPSS >20)
o TURP <100g
Intra-op: bleed, sepsis, urethral damage, TURP syndrome
Immed post-op: haematuria, clot retention, urinary retention
Late post-op: retrograde ejac, ED, redo (20% within 10y)
o Open retro-pubic prostatectomy (if large)
Risk factors for UTI, what makes UTI complicated, causes of UTI - bacteria and sterile pyuria
RISK FACTORS
-females
-sex
-pregnancy
-menopause
-immunosuppression
-diabetes
-urinary obstruction
-renal stones
-urinary catheter
Uncomplicated = normal renal tract and function
Complicated = abnormal renal tract, voiding difficulty/obstruction, reduced renal function,
impaired host defenses, virulent organisms e.g. staph aureus
Causes
Pyuria: -usually E. coli
-occasionally proteus mirabilis, staph aureus,
klebsiella pneumonia
CAUSES OF STERILE PYURIA
-treated UTI within 2 weeks
-inadequately treated UTI
-appendicitis
-calculi
-prostatitis
-bladder tumour
-polycystic kidneys
symptoms to differentiate pyelo vs cystitis vs prostatitis
examination and IX for UTI
SYMPTOMS
-pyelonephritis = fevers, rigors, vomiting, loin pain,
flank tenderness, oliguria (if AKI)
-cystitis = frequency, dysuria, urgency, haematuria, suprapubic pain
-prostatitis = flu-like symptoms, backache, enlarged prostate on PR, few urinary symptoms
EXAMINATION
-abdo/loin tenderness
-foul smelling urine, distended bladder if
obstruction
INVESTIGATIONS
-dipstick urine (look for nitrites, leukocytes,
bacteria)
-MSU – for culture and sensitivities
-BLOODS
– FBC, U and E, CRP, -blood culture if systemically unwell (urosepsis),
-PSA
IMAGING
– in children and men, failure to respond to treatment, recurrent UTIs, or pyelonephritis, consider USS and referral to urology
Prevention and management of UTI, + in pregnancy and in men
PREVENTION
-drink lots of water
-antibiotic prophylaxis
-self-treatment with single dose of abx when symptoms start
-cranberry juice (but need to drink lots!)
-no evidence for post-coital voiding!
MANAGEMENT
-drink lots of fluids and urinate often
Non-pregnant women:
-treat empirically for e. coli
-trimethoprim or nitrofurantoin
-if no response do urine culture
-consider other diagnoses if vaginal itch or discharge
-if upper UTI take urine culture and treat with Augmentin and gentamicin
-if asymptomatic DO NOT TREAT (very common)
In pregnant women:
-common
-get expert help
-any bacteriuria asymptomatic or
symptomatic) should be treated (risk of prematurity and pyelonephritis)
-repeat dipstick and culture at each antenatal visit
In men:
-uncommon
-often results from anatomical or functional anomaly
-consider referral to urologist and discuss with ID
Possible cases of relapse (same organism) or reinfection (different) of UTI, next IX and treatment
CAUSES
- Abnormal Renal/GU tract e.g. stones, posterior valves
- Voiding difficulty/outflow obstruction e.g.BPH
- Impaired renal function e.g. DM
- Impaired host defenses e.g. DM,
immunosuppression
- Poor hygiene/wiping technique
- Post-menopausal
Rest home/hospital
Diabetes
Kidney or bladder stones
Having a catheter
Previous urinary tract surgery
Sexual activity
Having an infected or enlarged prostate
Congenital abnormality of the urinary tract
Ix
INVESTIGATIONS
- Renal tract ultrasound
- PR
- Renal function test
TREATMENT
- eradicate/manage cause
- culture and sensitivity to rationalize antibiotics
- Oestrogen cream for post-menopausal females.
Prostate cancer - presentation, investigatons and exam
PRESENTATION
- Voiding: poor stream/flow, hesitancy, incomplete emptying, intermittency
- Storage: nocturia, freq, dribbling, overflow incontinence
- Haematuria
- Haematospermia, low ejac volume, ED (local invasion SV, ejac ducts)
- Boney pain (suggests mets)
- Weight loss, fatigue
-Age , Famhx as Risk factor
INVESTIGATION
DRE
- Enlarged, craggy, asymmetrical, nodular
o If PSA+, Prostate ca chance 30-40%
Bloods
- FBC: low Hb, pancytopenia
- ALP rise (mets)
- PSA >4 abnormal
o But normal in 30%
o PSA rise also w BPH, hyperCa, prostatitis, sex
o Note important to discuss PSA test with asymptomatic men who ask for it as screening
- Cr
MSU
- if blood cystoscopy, CT
Imaging
- TRUS (guide needle Bx)
o Need LA and abx cover
- CT staging
- Nuclear bone scan (mets)
Biopsy
- TUBP
grading and staging of prostate ca
Grading
- Gleason system - based on 2 most predominant glandular patterns each scored 1-5.
1= normal tissue well differentiated
2. well formed glands, larger and increased stroma
3. darker cells, some cells beginning to invade surrounding tissue
(2&3 moderately differentiated carcinoma)
4. few recognisable glands, many cells invading (poorly differentiated carcinoma)
5. sheets of cells throughout the surrounding tissue (anaplastic carcinoma)
Staging
- CT staging; Lymph Nodes (urethral), seminal vesicles,
bladder, bone lung
Management of prostate Ca + risks and prognosis
MANAGEMENT
Waitful watching life expectancy <10yrs, not
recommended for high risk patients
Active Surveillance >70y, low risk
Surgery
- Radical prostatectomy (open vs robotic)
o SE: impotency, urinary probs
Radiation
- Radical (daily 6/52)
o Similar outcomes to surgery
o SE: bowel, bladder probs, 2° Ca
- Palliative role (boney mets)
Brachytherapy
- Radioactive Iodine125
o Less aggressive cancers
o Retain potency, no 2 Ca
Chemotherapy
- Docetaxel
o Survival benefit for those w good performance
o Potential for salvage chemo in castrate resistance
Androgen deprivation/Hormonal
No change in life expectancy ‘lead time bias’
- Surgical
o Orchidectomy (decr libido)
- Medical
o LutHormRH agonist;
Zoladex, Lucrin (IM)
Cyproterone acetate (PO)
o Cover with anti-androgen
(Goserelin) for 2/52 to cover flare
o SE: lethargy, hot flush, mood, wt gain, decr muscle mass, Erectile D
PROGNOSIS
T low and PSA up = androgen independent
10% die at 6months; 10% live >10yrs

What is the aetiology, presentation and treatment of CKD complications: anaemia, bone disease, skin disease + their treatment
Anaemia
- erythropoietin deficiency:
presents: SOB, palpitations, pallor
Treatment :
EPO if CKD<3, Hb <100 – exclude iron deficiency first.
Aim Hb 110-120 (increase is stroke risk)
Renal osteodystrophy’ : combination of hyperparathyroid bone disease, osteomalacia, osteoporosis, osteosclerosis
Presents as bone pain
Treatment
1. Treat if high PTH
2. Restrict dietary phosphate from milk, cheeze, eggs
3. Phosphate binders reduce absorption– eg. Calcitab
-Monitor with phosphate
4. Calcitriol increases calcium
– monitor with PTH
Skin Disease
-Retention of nitrogenous waste products, +/- inadequate dialysis
- porphyria cutanea tarda (PCT)
- Nephrogenic systemic fibrosis – a systemic
fibrosing disorder with predominant skin
involvement 2° to gadolinium contrast
Presents with pruritis, dry skin + eczematous lesions over AV fistula
PCT : is a blistering, photosensitive rash
