Decrease sodium reabsorption so higher conc of Na+ reaches the collecting duct. Increase potassium excretion. Increase calcium reabsorption.
Have a vasodilator effect.
123
Adverse effects of thiazide diuretics?
```
Hyponatraemia
Hypokalaemia
Hypomagnesia
Hypercalcaemia
Hyperuricaemia
Hyperglycaemia

125
Where do potassium sparing diuretics act? What subtypes are their and where do they act?
Act in the collecting duct.
Aldosterone antagonists compete with aldosterone binding to intracellular receptors. This causes reduced gene expression and reduced synthesis of a protein mediator that activates sodium channels in the apical membrane.
Amiloride and triamterene block the apical sodium channel decreasing sodium reabsorption.
126
How effective are potassium sparing diuretics? Why are they acceptable in patients with low potassium?
They are weak diuretics alone- however used in conjunction with loop or thiazide they increase the effect.
They don't excrete potassium unlike loop and thiazide diuretics.

130
Which drug is absorbed better from the GI tract, amiloride or triamterone?
Triamterone.
131
Carbonic anhydrase inhibitors are not used as diuretics anymore. True or false?
True
132
What are carbonic anhydrase inhibitors used for?

Used in alkolinase urine
Some forms of infantile epilepsy and acute mountain sickness.
133
How do carbonic anhydrase inhibitors work?
They inhibit the carbonic anhydrase enzyme present on the PCT causing excretion of bicarbonate along with Na+, K+ and water.
134
Effects of carbonic anhydrase inhibitors on ion concentrations? Also adverse effects?
Hyponatraemia
Hypokalaemia
Metabolic acidosis.
135
Why do loop diuretics and thiazide diuretics cause hypokalaemia?
Increased load of Na+ is sent to the distal convoluted tubule and collecting duct. This means enhanced reabsorption of sodium occurs here and potassium is secreted as a consequence.
136
How do low potassium levels present?
Weakness, fatigue, arrhythmias and myalgia.
137

142
Why are ADH analogues effective in low sodium?
They allow you to have water loss without losing sodium.
143
What receptors do ADH analogues act on?
V (vasopressin)- 2- causes vasodilation and water reabsorption in the CD.
144
Name an ADH analogue and compare its effectiveness to ADH?

Nephrogenic- inability of the nephron to respond to
Also used in bedwetting/nocturnal enuresis in children
Control variceal bleeding in portal hypertension.
146
How do aquaretics/vaptans work?
They are competitive antagonists of vasopressin receptors (V1A, V1B and V2)
V2 mediate water reabsorption in the CD by directing aquaporin 2 containing vesicles to the apical membrane.
147

150
What do most men present with in terms of urinary incontinence?
Overflow incontinence
151
What is the most common type of urinary incontinence?
Stress
152
Describe the two phases of the micturition cycle?
Storage phase- bladder starts to fill. Pressure increase is stopped by accommodation from the detrusor muscle in the bladder wall keeping it constant.
Voiding phase- There is now an increased vesicular pressure causing the urethral sphincters to relax and allow emptying.
153
What nerve supply controls the storage phase?
Sympathetics (via T10-L2 hypgastric nerves)
154
What nerve supply controls the voiding phase?
Parasympathetics (pelvic splanchnic nerves S2-S4)
155
Describe overflow incontinence?
Usually occurs due to an obstruction to the urethra causing retention in the bladder. Over time (months to years) if it is chronic retention- the bladder will start to fill up more and more with urine stretching the detrusor muscle. Eventually it will stop working.
156
Presentation of overflow incontinence?
Incontinence at night and in places that are not sensible (they do not realise their bladder is full)
Due to an increase in intravesicular pressure (due to the detrusor muscle losing compliance) there is an increase in pressure in the renal pelvis causing acute kidney disease.
157
Presentation of urge incontinence
Daytime frequency (every 15-20 mins)
Small voided volumes
Sense of urgency
Eneuresis (leakage of urine at night)
158
What causes urge incontinence?
Could be due to detrusor overactivity- detrusor contractions occurring during inhibition of voiding.
Diagnosed by urodynamics.
Also could be due to afferent nerves being over-stimulated. Occurs when something is irritating the bladder e,.g. bladder stones or tumours.
Could be due to excess central facilitation- overactivity of pudendal nerve allowing relaxation of the external sphincter.
Or paraplegia- loss of central inhibition
Destruction of the S2 S3 centre- bladder becomes inert bag.
Pelvic surgery or fracture damaging parasympathetic nerves.
159
Describe stress incontinence?
Incontinence due to increased intra-abdominal pressure without detrusor contraction.
160
What causes stress incontinence?
Due to damage to the pelvic floor or urethral function during childbirth.
161

167
Why do the elderly get urinary incontinence?
Multifactorial- immobility, dementia, drugs, obstruction, neuropathy, pelvic floor weakness.
168
What are alternative forms of urinary incontinence (not urethral)?
Extraurethral route- ectopic ureter- rare and congenital
| -fistula- vesico-vaginal fistula- important in developing countries due to obstructed labour.
169
