Urology Flashcards
(178 cards)
Name 3 storage LUTS and 4 voiding LUTS.
Storage= frequency, urgency, urge incontinence, nocturia Voiding= hesitancy, slow flow, terminal dribbling, haematuria, dysuria, incomplete voiding
Following taking a history of LUTS, name 3 important parts of the examination.
Abdominal examination- importantly noting bladder distension/palpable
Examine external genitalia- e.g. looking for phimosis or meatus stenosis
DRE
Give 3 investigations that may be used to investigate LUTS.
Uroflowmetry Bladder scan for post-void residual volume Urine dipstick MUS for culture and sensitivities PSA and renal function bloods Frequency volume chart Urodynamic testing US of kidney for hydronephrosis if renal function impaired or residual volume is high
Give 2 common causes of storage LUTS
and 2 common causes of voiding LUTS
Storage= overactive bladder, cystitis, bladder tumour, bladder calculi Voiding= BPE, prostate cancer, urethral stricutre, meatal stenosis, phimosis
What zone of the prostate does BPH usually arise?
Transitional zone
What does BPE feel like on DRE?
Soft enlarged gland
Which enzyme converts testosterone to its more potent form, DHT?
5-alpha reductase
How is testosterone linked to BPE?
DHT binds to receptors in the prostate gland, increasing secretions and possibly cell division, resulting in gland enlargement
What is first line medical therapy for BPE? Give an example drug and how it works.
Alpha blocker e.g. Tamsulosin.
Alpha 1 adrenoceptor antagonist, relaxes smooth muscle
What is second line medical therapy for BPE? Give example drug and how it works.
5-alpha reductase inhibitors e.g. Finasteride
Inhibits conversion of testosterone to dihydrotestosterone
What are 2 surgical management options for BPE?
TURP, laser prostatectomy, open prostatectomy, aquablation
Give 4 causes of a raised PSA.
Prostate cancer, BPE, UTI, prostatitis, urinary retention, catheterisation, ejaculation, exercise e.g. cycling
What is the most common type of prostate cancer?
Adenocarcinoma
75% of the time, prostate adenocarcinoma originates from what zone of the prostate?
Peripheral zone
True/false: adenocarcinoma of the prostate is multifocal 80% of the time.
True
What does prostate cancer feel like on DRE?
Craggy, hard, irregular gland
What investigations are used to further investigate prostate cancer following a raised PSA?
MRI, transrectal US guided biopsy, bone scan if bone mets suspected
What grading system is used for prostate cancer? What does it use to grade the cancer?
Gleason grading
Uses histology from prostatic biopsy
Where are the likely metastatic sites of prostate cancer?
Most frequently bone, then lung and liver
What is the management of low risk or intermediate risk localised prostate cancer?
Active surveillance or
Radical prostatectomy
Other than radical prostatectomy and active surveillance, outline other treatment options for prostate cancer.
Radiotherapy (brachytherapy and/or external beam radiation
Androgen deprivation therapy
Symptomatic e.g. bisphosphonates, ureter stent
What types of drugs are used in androgen deprivation therapy in prostate cancer?
LHRH antagonists or LHRH agonists
What risk prostate cancers is androgen deprivation therapy suitable for?
Intermediate, high risk and metastatic cancers
Give 3 risk factors for prostate cancer.
Age, family history, ethnicity (Afro-Caribbean), diet (high animal fat) and obesity, UV radiation
