what are the four different types of incontinence?
- stress
- urge
- overflow
- functional
symptoms of stress incontinence?
leakage when increased intrabdo pressure (e.g. coughing or laughing)
- urgency
- frequency
symptoms or urge incontinence?
related to OAB (detrusor overactivity)
- frequency
- urgency
- nocturia
symptoms of overflow incontinence?
unable to completely empty bladder secondary to bladder outlet obstruction (BOO) or detrusor inactivity
- constant dribbling
- frequent urination with only small amounts
symptoms of functional incontinence?
disability means they cannot reach toielt in time e.g. walking with aid
- urgency
- frequency
- nocturia
managament of stress incontinence (conservative and pharm)
conservative:

- retropubic mid-urethral mesh sling
- intramural urethral bulking agents
management for urge incontinence?
conservative: (for women)
- reduce caffeine
- stop XS fluid intake
- stop smoking
- lose weight
- offer bladder training (for at least 6 wks)
pharm:
- anticholinergic e.g. oxybutynin (not great in older people!)
- second line: mirabegnon
what is teh memory loss pattern like for dementia
in early stage of dementia pts start to lose their short term memory -> then long term as the disease progresses
managment of overflow incontinence?
treat underlying cause of bladder outflow obstruction e.g. surgery to remove blockage, meds to shrink prostate, self catherisation (for detrusor inactivity)
managment of fucntional incontinence?
using behavioural methods that teach you to urinate on a timed voiding schedule and by modifying your environment so you can get to and use the toilet more quickly. This may involve moving furniture, making clothes easier to remove, or making other changes
what is importatn as part of a continence examination? (examinations and invesitgations)
- review of bladder and bowel diary
- abdo examination
- urine dipstick and MSU
- PR exam (will commonly have an impacted rectum if have a full bladder) + prostate in male
- external genitalia review particularly lookign fro atrophic vaginitis in female
- post micturition bladder scan
finasteride: class, indications, SE
5-alpha reductase inhibitor
BPH
sexual dysfunction, testicular pain, breast abnormalities
oxybutynin: class, indications, SE
anticholinergic
reduce detrusor overactivity
Constipation, dizziness, dry mouth, headache, n+v, palpitations, tachycardia
doxazosin and tamsulosin: class, indications, SE
both alpha blockers
both used for BPH but doxazosin can also be used to lower BP
arrythmias, chest pain, cough, dizzines, dry mouth, hypotensions, n+v, headahce
mirabegron: class, indications, SE
beta blocker
used for OAB
arrythmias, constipation, diarrhoea, dizziness, headache, icnreased risk fo infection, nausea
name 3 other medications used to treat OAB (bar oxybutynin and mirabegron)
- solifenacin
- trospium
- tolteradine
if faecal incontinence is suspected what exmiantions need to be done?
- PR examination-> assess rectum, prostate, anal tone and sensation as well as visual inspection of the rectum
- assess stool type as well
- abdo examination
what is the reassoning behind older persons getting faecal incontinence?
as body ages, rectum can become mroevacous and the anal sphincter cna gape due to a number fo factors e.g. haemorrhoids, chronci constipation
cannot exert the same amount of intrabdo pressure so and muscle tension to force out a stool
managment for constipation?
- enemas
- stool softeners (NEEDED if stool is hard as otherwise wont come out with just stimulants)
- stimulants
- manual evacuation if difficult cases
- in older pts any drug that cuases constipation is prescribed alongside laxative always
before chronic diarrohea can be managed what investigations need to be done to exclude underyling cuases?
- bowel imaging
- stool culture
- causative medications removed
- faecal impact needed to be excluded
managment of chronic diarrhoea?
regualr toileting and dietary review
then
low dose loperamide trialled then constipating and enema regimes used if this doesn’t work
which two assessments are important to be done for elderly people to plan future healthcare?
- clinical frailty score
- comprehensive geriatric assessment
name some common stroke complications?
- recurrent stroke and extension of stroke
