These may include urinary urgency, frequency, urge incontinence, nocturia, hesitancy, interrupted stream and incomplete emptying Mechanism of bladder dysfunction in MS Normal voiding is achieved by contraction of the detrusor muscle and relaxation of the urethral sphincter functioning together. Incoordination of this mechanism causes the urethral sphincter to remain contracted resulting in an inability to void, or result in hesitancy or may lead to interrupted or incomplete voiding (detrusor sphincter dyssynergia). Lesions of the brain and spinal cord may result in excess reflex activity (detrusor hyper-reflexia) and cause an increased urge to pass urine and possible incontinence. Lesions affecting the lower cord and nerves may result in the bladder being unable to contract effectively. This results in incomplete emptying and a large post void residual volume of urine. This may predispose to recurrent urinary tract infections and renal damage from hydronephrosis. Management Collect MSU A urine sample should be collected and a urine dipstick performed. If this is abnormal a specimen should be sent for microscopy, culture and sensitivity. Bladder Diary The patient should keep a bladder diary for 3 days to identify symptoms of storage and emptying, assess the frequency of voiding and identify any contributing causes, e.g. poor fluid intake. Ultrasound Bladder Scan If this demonstrates a post void residual volume of 150mls or less with no history of urinary tract infection, bladder retraining can be commenced to improve a neurogenic overactive bladder. This involves gradually increasing the time between voiding form as little as 5-10 minutes initially until a 3-4 hour pattern is achieved. Anti-cholinergic medication may assist with bladder retraining (see overleaf), but should only be prescribed with caution if the post void residual volume of urine is in excess of 100mls (a further bladder USS post-treatment should be considered). Patients should be advised of the common side effects. Bladder emptying techniques, such applying pressure to the bladder and double voiding, should be taught. If the post void residual volume of urine is greater than 150mls intermittent self-catheterisation should be advised. Those with a combination of storage and voiding problems may benefit from combining intermittent self-catheterisation and anti-cholinergic medication. If the post void residual volume of urine is greater than 400mls in a symptomatic individual, immediate catheterisation should be considered (intermittent or permanent) whist an urgent specialist opinion is sought. For patients with significant on-going pain, incontinence or haematuria in the absence of infection an early specialist opinion is advised. Guidelines developed July 2006 by the South East Regional Multidisciplinary MS Group with advice from Sue Foxley, Nurse Consultant, Continence Care, KCH and Prof Cardoza, Consultant Urogynaecologist, KCH Current Anticholinergic Medication used in Neurogenic Bladder Problems NAME Tolterodine (Detrusitol) DOSE 1 – 2 mg twice daily Tolterodine modified 4 mg daily release (Detrusitol XL) Oxybutynin (Ditropan) 2.5 – 20mg daily ADVANTAGES AND COMMON SIDE EFFECTS Adv: Reduces urgency and frequency. SE: Mild dry mouth, constipation, blurred vision, dry eyes, drowsiness, difficulty voiding, facial flushing, dizziness, indigestion, fatigue, flatulence, chest pain, peripheral oedema, parasthesia As Tolterodine but better tolerated Adv: Reduces urgency and frequency. SE: Very dry mouth, constipation, blurred vision, dry eyes, drowsiness, difficulty voiding, facial flushing, dizziness As Oxybutynin but better tolerated Oxybutynin modified 5 – 30mg daily release (Lyrinel XL) Oxybutynin Transdermal patches (Kentera) 3.9 mg/24hours applied As Oxybutynin, better tolerated, skin reactions twice weekly Solifenacin (Vesicare) 5 – 10 mg once a day Trospium chloride (Regurin) 20 mg twice (before food) Adv: More selective for nerve endings in bladder, reduces leakage. SE: As Oxybutynin and gastro-oesophageal reflux, altered taste, fatigue, oedema daily Adv: Less effect on the brain; does not interact with other drugs. SE: As Oxybutynin and flatulence, chest pain, dyspnoea, rash and asthenia Drugs used to reduce urine output 10 – 40 micrograms Desmopressin acetate once a night Nasal spray (Desmospray, Nocutil Desmopressin acetate (Desmotabs) 200 – 400 micrograms once a night Caution: Limit fluid intake to minimum from 1 hour before dose until 8 hours afterwards. Periodic blood pressure and weight checks needed SE: Fluid retention and hyponatraemia, stomach pain, headache, nausea, vomiting, allergic reactions Caution: Limit fluid intake to minimum from 1 hour before dose until 8 hours afterwards. Periodic blood pressure and weight checks needed SE: Fluid retention and hyponatraemia, stomach pain, headache, nausea, vomiting, allergic reactions Guidelines for the treatment of Neurogenic Bladder Problems in Multiple Sclerosis Troublesome urinary symptoms (Hesitancy / incomplete voiding / nocturia / incontinence / frequency / urgency) Dipstick Urine (in line with MHRA guidance*) Send for MSU and treat with antibiotics Abnormal Normal Address contributory factors, e.g. fluid intake, caffeine / alcohol, constipation Ongoing symptoms Three day bladder diary and formulate care plan. Reassess after one month Ongoing symptoms Post-micturition bladder USS Residual less than 150 ml Add anticholinergics Repeat bladder USS if further symptoms Residual greater than 400ml Consider immediate catheterisation & urgent referral as below Residual 150 – 400ml Teach double-voiding, percussion, positioning, vibration & association. Reinforce life-style advice. Rescan after 3 months Ongoing symptoms ICSC +/- anticholinergics Ongoing symptoms Patient unable to manage ISC Supra-pubic catheter with flip-flow valve if suitable or leg bag Ongoing symptoms Refer for specialist opinion (urology / urogynaecological / continence services) This is a guideline only. Management of an individual patient is a collaboration between MS nurse, neurologist, continence nurse and urologists / urogynaecologist. Individual patient management will vary depending on the facilities available in different geographical regions. * MRHA / DoH (2006) Point of Care Testing, Urine Dipsticks Top Tips: Advise for health care professionals. dh@prolog.uk.com for copies
