Q

What are the different types of urinary incontinence?

A

Stress
=> physical movement/activity places stress on the bladder, poor closure of bladder during childbirth is RF
Urge
=> urine leaks as you feel sudden intense urge to pee, detrusor overactivity
Functional
=> aware of need to pee but unable to go due to physical/mental reasons
Overflow
=> involuntary release of urine from full bladder, in absence of any need to urinate

18
Q

Epididymitis + orchitis summary card

Painless hard testicular mass, testicular swelling/discomfort, backache (mets via para-aortic nodes)
- seminoma
- non-seminoma (teratoma)
- sertoli/leydig cell tumours
21
Q

Testicular cancer tumour markers

A

22
Q

Ix for scrotal masses

A

Check for infection
- urine dipstick, MSU, sexual health hx if indicated
- bloods: FBC, CRP
O/E
- can you get above the mass? (if not = inguinal hernia)
- does it transilluminate? (if yes = fluid)
- is it reducible?

23
Q

Ix for testicular cancer

A

Tumour markers (AFP, beta-hCG, LDH)
Testicular USS
CT to allow for staging

24
Q

Why are varicoceles more common on the left testes?

A

Left testicular vein connects to the left renal vein at 90 degrees so increased reflux from compression of the left renal vein or a lack of effective valves is more likely to present with a varicocele > right testes

25
Q

A 67-year-old man has been urinating around 12-14 times per day over the past 6 months. His stream is ‘weak’ and often takes a long time to get going. After he has finished urinating, he does not feel fully empty and often dribbles a little bit. DRE reveals a smoothly enlarged prostate gland with a palpable midline sulcus. A diagnosis of benign prostatic hyperplasia is made. He is eager to avoid surgery if possible. Which treatment would be best for him?

B Solifenacin
C Tamsulosin
D Nitrofurantoin 
E Co-trimoxazole
A

C Tamsulosin

Which first-line investigation should be used to confirm the diagnosis?

A PSA 
B Acid phosphatase

33
Q

A 50-year-old man has developed a swollen scrotum that has been bothering him for the past 2 weeks. The swelling is uncomfortable but not painful. On examination, the left hemiscrotum is enlarged, fluctuant and non-tender. It is possible to get above the swelling, however, the left testicle cannot be distinguished from the swelling.

C Testicular tumour 
D Epididymal cyst 
E Indirect inguinal hernia

B Hydrocoele

34
Q

A 30-year-old man has developed a swollen scrotum that he first noticed a week ago. He adds that the swelling feels like a ‘bag of worms’, and is uncomfortable but not painful. On examination, the patient’s scrotum looks normal when lying down, however, the left hemiscrotum becomes swollen when he stands up. The GP can get above the swelling and distinguish it from the testicle. What is the most likely diagnosis?

A Indirect inguinal hernia 
B Direct inguinal hernia 
C Hydrocoele 
D Varicocoele 
E Epididymal cyst
A

D Varicocoele

35
Q

A 21-year-old man visits his GP complaining that his scrotum feels ‘heavier than usual’. On examination, a firm, non-tender lump can be palpated at the base of the right testicle. The patient had an undescended testicle as a child, which was corrected with orchidopexy. Testicular cancer is suspected and a CT scan is requested to assess for spread. Which group of lymph nodes does testicular cancer spread to?

A Inguinal
B Femoral
C Para-aortic 
D Iliac
E Mesenteric
A

C Para-aortic

36
Q

A 32-year-old man presents with a 2-week history of frequent urination and excessive thirst. He has also noticed that he feels much weaker than usual, and is struggling to complete his usual gym routine. He has been to see his GP once before because his blood pressure was high on multiple occasions, however, he did not return to receive treatment. His blood pressure is measured again and it is 184/94 mm Hg. What would you expect to see on the ECG of this patient?

A Tented T waves 
B Absent P waves 
C ST elevation 
D J waves 
E U waves
A

E U waves

Pt has Conn’s syndrome => hypokalaemia, which induces nephrogenic diabetes insipidus, which, consequently, leads to polyuria and polydipsia. Furthermore, muscle weakness is another feature of hypokalaemia. The main ECG features of hypokalaemia are U waves, ST depression, flattened T waves and prolonged PR interval.
