here give the knowledge that you should possess to manage acute and chronic urine retention. the lecture is more concerned about practical patient care and ward setting management. you should minimally be aware about following facts regarding urine retention. the multiple causes of retention will be discussed later in detailed manner. Direction of the lecture seems more toward BPH and acute retention management. beware there are many aspects of a patient present with an AUR. do no harm and always try to keep patient satisfaction. Let me know about your comments an Ideas. try to improve the quality. good luck.
3. Acute retention
• Acute urinary retention (AUR) is the sudden inability to
pass urine. It is usually painful
4. Chronic retention
• Non painful bladder that remains palpable after voiding
• inability to completely empty the bladder despite
maintaining an ability to urinate, which results in
elevated postvoidal residual (PVR) urine volumes
5. Causes of Urine retention
• Obstructive
• Infectious and inflammatory
• Drug induced
• neurological
• Other causes.
6. Obstructive causes common to men
• Benign prostatic hyperplasia;
• meatal stenosis;
• paraphimosis;
• penile constricting bands;
• phimosis;
• prostate cancer
7. Obstructive causes of Urine retention common
to females.
• Organ prolapse (cystocele, rectocele, uterine prolapse);
• pelvic mass (gynecologic malignancy, uterine fibroid,
ovarian cyst);
• Retroverted gravid uterus
8. Obstructive causes common to both genders
• Aneurysmal dilation;
• bladder calculi;
• bladder neoplasm;
• fecal impaction;
• gastrointestinal or
retroperitoneal
malignancy/mass;
• urethral strictures,
• foreign bodies,
• stones,
• edema
9. Infectious and inflammatory
Men
• Balanitis;
• prostatic abscess;
• prostatitis
Women
• Acute vulvovaginitis;
• vaginal lichen planus;
• vaginal lichen sclerosis;
• vaginal pemphigus
12. Neurological
• More often causing chronic retention but may cause AUR:
• Autonomic or peripheral nerve (eg, autonomic neuropathy, diabetes
mellitus, Guillain-Barré syndrome, pernicious anaemia, poliomyelitis,
radical pelvic surgery, spinal cord trauma, tabes dorsalis).
• Brain (eg, cardiovascular disease (CVD), multiple sclerosis (MS),
neoplasm, normal pressure hydrocephalus, Parkinson's disease).
• Spinal cord (eg, invertebral disc disease, meningomyelocele, MS, spina
bifida occulta, spinal cord haematoma or abscess, spinal cord trauma,
spinal stenosis, spinovascular disease, transverse myelitis, tumours, cauda
equina).
13. Other causes
• In men - penile trauma, fracture or laceration.
• In women - postpartum complications (increased risk
with instrumental delivery, prolonged labour and
caesarean section);[2]urethral sphincter dysfunction
(Fowler's syndrome).
• In both - pelvic trauma, iatrogenic, psychogenic.
14. Features of acute retention
• Pain in abdomen
• History of inability to pass urine
• Distended bladder on palpation
15. BPH one of the common causes of urine
retention
• lower urinary tract voiding symptoms, including
frequency, urgency, nocturia, straining to void,
weak urinary stream, hesitancy, sensation of
incomplete bladder emptying, and stopping and
starting of urinary stream(LUTS)
16. BPH
• Usually causes a chronic retention but usually these
people comes to the attention when they get an Acute on
Chronic retention
• Otherwise these people most of the time unaware about
the LUTS which are due to the BPH
17. History taking. Pay attention about….
• Course of development including onset and progression.
• Have you any fever?
• Any previous episodes? Any history of BPH?
• LUTS?
• Past medical history, neurological disease, other medical
conditions.
• Take the drug history.
• Ask about alcohol, constipation, long travel, low fluid intake, high
fluid intakes.
18. Examination
• Is the patient warm?-fever
• Abdominal - a tender enlarged bladder with dullness to percussion well above the
symphysis pubis, often almost to the level of the umbilicus.
• Look for phymosis, meatal stenosis and look for signs of infections in genitalia.
• In females- look for cystoceles, rectoceles, UV prolapsy, do a Vaginal examination
and look for pelvic mases. Look for vulval infections and inflammations, gravid
uterus obvious thing.
• Do a DRE/PR examination in males. Look for enlarged prostate.
• Do a neurological examination to detect neurogenic bladder.
19. Blood tests:
•FBC.
•U&E, creatinine, estimated glomerular filtration rate
(eGFR).
•Blood glucose.
•Prostate-specific antigen (PSA).
NB: this is elevated in the setting of AUR so is of
limited use at this stage.
20. Imaging studies.
• Ultrasound - commonly used, as it can provide a measure of post-void
residual urine as well as looking for hydronephrosis and other
structural abnormalities of the renal system.
• CT scan-exclude intra abdominal masses.
• MRI/CT brain scan-exclude Space occupying lesions in brain.
• MRI scan of the spine - used to look for disc prolapse, cauda equina
syndrome, spinal tumours, spinal cord compression, MS.
• cystoscopy, retrograde cystourethrography or urodynamic studies
21. management
• Acute urine retention should be managed immediately.
• Decompression by a suitable catheter.
• If possible, the use of chronic urethral indwelling catheters should be avoided
• If the initial cauterization attempts are failed call a doctor familiar with advanced
catheterization techniques.-angulated Coude catheter or a suprapubic catheter
• For people with BPH the duration of the cauterization yet remain under investigations
and studies. For an example while the author was a intern doctor catheterization for
AUR done and the catheter kept in for 2 weeks with an alpha blocker like tamsulosin.
• If the prostate Is palpable in a PR/DRE finesteride can be started with tamsulosin.
• neurogenic bladder related urine retention should be managed with clean
intermittent self catheterization.
22. Few useful comments by American association
of family physicians.
• In a patient with a AUR due to BPH start a alfablocker at the time of catheterization.
• Men with urinary retention from benign prostatic hyperplasia should undergo at least one
trial of voiding without catheter before surgical intervention is considered
• Prevention of acute urinary retention in men with benign prostatic hyperplasia may be
achieved by long-term treatment with 5-alpha reductase inhibitors.ex-finesteride.
• Silver alloy-impregnated urethral catheters reduce the incidence of urinary tract infections in
hospitalized patients requiring catheterization for up to 14 days.
• Suprapubic catheters improve patient comfort and decrease bacteriuria and recatheterization
in patients requiring catheterization for up to 14 days.
• Low-friction, hydrophilic-coated catheters increased patient satisfaction and decreased
urinary tract infection and hematuria in patients with neurogenic bladder who practice clean,
intermittent self-catheterization.
23. As the management have a major role with
catheterization knowledge about catheterization is
vital.
• Do not harm!-direction or the order for catheterization always should taken by a
qualified doctor.
• DON’T ALLOW ANYONE TO CATHERIZE A PATIENT IF HE/SHE HAS NO
KNOWLEDGE ABOUT GENITAL ANATOMY AND URINARY TRACTS. (you are the
doctor don’t be hesitate to lead or do whatever the procedure you have the skill to
do when there is a good indication. You are the major role in hospital.)
• SELF CATHERIZATION-patients obviously need a training.
• Difficult catheterization? Take senior opinion, A Surgeon, a senior medical officer
who has a practice with advancer urinary catheter techniques.
27. Contra indications for catheterization.
• Urethral trauma
• Patients with pelvic fractures.
• Blood at meatus.
• DRE-high riding prostate.
• Scrotal haematoma.
28. TWOC-trial without catheter
• Consider for people who is especially presented with BPH.
• It is done to confirm the patients ability to pass urine him self without difficulty.
• In a TWOC patient can send home without catheter or some times re
catheterization is needed.
• A supra pubic catheter will be clamped before the procedure.
• Procedure takes 4-6 hours.
• Cather will be removed some water will be provided to drink. you will be asked to
urinate when you have a urge.
• Then a doctor will be perform a USS to confirm postvoidal urine volumes in
bladder.
29. TWOC
• The trial is successful if you pass urine by 4-6 hours and
have less than 150ml urine left behind in the bladder. You
can then go home.
• Take 1-2 liters of fluids when you go home for a day.
• Urinate every 4-5 hours.
30. • Keep patients informed who has indwelling
catheters about care, possible complications like
UTIs.
• Read more about the catheter care.
