Urinary Continence Mechanisms Nursing Management on Male Urinary Incontinence Stable detrusor Competent bladder neck Intact external sphincter mechanism TO Hoi Chu Nurse Specialist (Urology) Division of Urology / Department of Surgery Queen Elizabeth Hospital Types of Urinary Incontinence Overflow Urge Stress Bladder pressure overcomes urethral pressure only at very high bladder volume urine loss accompanied by urgency resulting from abnormal bladder contractions urine loss resulting from sudden increased intraintra-abdominal pressure (eg, laugh, cough, sneeze) Common Causes of Bladder Problems URGE & OVERACTIVE BLADDER: occurs when the bladder contracts when it shouldn’t, due to an unstable bladder problem. Mixed combination of stress and urge incontinence STRESS: occurs when increased pressure on the bladder can’t be supported by weak pelvic floor muscles. Functional Factors outside the Bladder or Urethra, e.g. OVERFLOW: occurs when there is blockage in the urethra or the bladder is damaged and can’t properly contract. Cognitive Impairment, Chronic Functional Disability, Psychological Impairment, Environmental Barriers 1 Overactive Bladder (OAB) Prevalence 16% men (16% of them have urine leaks) more common after 64 17% women (55% have urine leaks) more common after 44 Morbidity of OAB falls & fractures depression UTI & skin infection Assessment of patient’s symptoms number of pads used nocturia fluid intake frequency-volume chart Risk factors: alcohol, caffeine, diuretics 2 Frequency-volume chart Treatment of OAB Eliminate underlying cause UTI / bladder stone Reduce caffeine and alcohol use e.g. coffee, tea, sodas, chocolate, medications, alcohol Caffeine: acts as a local irritant and as a diuretic Alcohol: a local irritant and powerful diuretic, ethanol relaxes the pelvic floor , sedation, delirium, and immobility Fluid management Eliminating underlying cause Bladder training Drug therapy Surgery 咖啡咽來源 類型 份量 毫克 咖啡 釀造 5 oz 100100-164 即溶 5 oz 5050-75 脫除咖啡因 5 oz 2-4 1-分鐘釀造 5 oz 2020-34 3-分鐘釀造 5 oz 3939-50 5-分鐘釀造 5 oz 3939-50 冰茶 12 oz 6767-76 巧克力奶 5 oz 2-15 熱巧克力 5 oz 2-15 可樂 12 oz 46 健怡可樂 12 oz 46 蛋糕 1/16 of 9” 9” cake 14 雪糕 2/3 cup 5 牛奶巧克力 1 oz 1-15 深巧克力 1 oz 20 茶 巧克力飲品 汽水 巧克力甜品 巧克力糖果 3 Caffeine: Practice Implications Caffeine Intake: Evidence Following caffeine intake, women with detrusor overactivity showed detrusor pressure with bladder filling, while continent women did not Women with detrusor overactivity had higher caffeine intake than women without diagnosis, even after controlling for age and smoking Reducing or restricting caffeine intake, especially in those with high daily intakes (> 5 drinks/day), may be helpful in reducing UI Besides coffee, tea, colas, other soda, some water products, and drugs contain caffeine Taper caffeine slowly to avoid migraine-type headache WHO, Second International Consultation on Incontinence, 2001 Fluid management Drink water excessively worsen irritative bladder symptoms Minimize their fluid intake to unacceptable levels, thinking that if they drink less, they will experience less incontinence Concentrated urine may lead to bladder irritation and actually worsen urge incontinence In addition, dehydration contributes to constipation Restrict fluids after dinnertime reduces nocturia, nighttime bed-wetting Bladder retraining Deferment technique 4 Behavioral Treatment Multi-component Programs Pelvic floor muscle training (PFMT) Home practice and exercise Voiding Urge schedules suppression strategies Self-monitoring Fluid (bladder diaries) and diet management Encouragement Bladder Training Patient education Scheduled voiding regimen Urge control strategies Self-monitoring Reinforcement (motivation) Wilson PD et al.

BMC Urology 2007, 7:2 8 Mechanism of PFME Contraction of the puborectalis lifts the urethra, enabling the external urethra sphincter to contract against it to prevent urine flow (Myers, 1991; De Ridder, 2005). Contraction of the pelvic floor also triggers an inhibitory spinal cord reflex that reduces bladder sensitivity and suppresses involuntary bladder contractions (Stein et al., 1994; Bo and Berghmans, 2000). Pelvic floor muscle exercise How to Identify your Pelvic Floor Muscles Sit or lie comfortably with muscles of your thighs, buttocks and abdomen relaxed. Tighten the ring of muscle around the back passage as if you are trying to control diarrhoea or wind. Relax it. While you are passing urine, trying to stop the flow midmid-stream, then restarting it. If your technique is correct, each time that you tighten your pelvic floor muscles you may feel the base of your penis move up slightly towards your abdomen. Doing Pelvic Floor Muscle Exercises Tighten and draw in strongly the muscles around the anus and the urethra all at once. Lift them up inside. Try and hold this contraction strongly as you count to ten, then release slowly and relax for 10 seconds. Repeat ("squeeze and lift") and relax. It is important to rest in in between each contraction. Repeat this as many times as you are able up to a maximum of 10 squeezes. Make each tightening a strong, slow and controlled contraction. Now do five to ten short, fast, but strong contractions, pulling up and immediately letting go. Do this whole exercise routine 10 times every day. You can do it in a variety of positions - lying, sitting, standing, walking. While doing the exercises: DO NOT hold your breath. DO NOT push down instead of squeezing and lifting up. Pelvic floor muscle exercise Make the Exercises a Daily Routine Tighten your pelvic floor muscles also while you are getting up from a chair, coughing or lifting assist themselves in regaining control Good results take time, takes several weeks to see improvement When you have recovered control of your bladder, you should continue doing the at least once a day for life. Other Tips to Help Your Pelvic Floor Avoid constipation and prevent any straining during a bowel movement. Seek medical advice for hayhay-fever, asthma or bronchitis to reduce sneezing and coughing. Keep your weight within the right range for your height and age. Share the lifting of heavy loads. 9 Pelvic Muscle Assessment modified Oxford Scale Neuromuscular Electro-Stimulation Neuromuscular Electro-Stimulation is an addition to PFME in the rehabilitation of weakened pelvic muscles and can be used in junction with biofeedback or PFME Goal: Help identify and augment pelvic muscle contraction Beneficial for both men and women Stimulation must be performed for a minimum of 4 weeks and continue PFE after the treatment Contraindications for Neuromuscular Electro-Stimulation On-demand pace makers Urinary retention Urethral obstruction Impaired cognitive function / Dementia Pelvic cancer Complete denervation of the pelvic floor (will not respond) Unstable or serious cardiac arrhythmia Pregnancy or planning/attempting pregnancy Broken/irritated peri-anal skin Rectal bleeding Active infection (UTI/vaginal) Unstable seizure disorder Swollen, painful hemorrhoids Use of Electrical Stimulation for Strengthening Pelvic Floor Muscles Vaginal or anal surface electrodes May help stress incontinence, although physiological reasons unclear Possibly educates patients to contract muscles 10 Electrostimulation of the pelvic floor musculature Transform fast twitch muscle fibers into slow twitch muscle fibers Recommendation: 20 weeks training (American college of Sports Medicine 1990) Almost no complications Recommendations In patients with incomplete denervation of the pelvic floor muscle and the striated sphincter, electrostimulation via anal or vaginal plugs performed over months, may be an option to improve pelvic floor function, thus improve incontinence. The incompleteness of the lesion should be as such that the patient is able to contract voluntary the pelvic floor even if this is weak (Grade C/D) Neuromuscular Electro-Stimulation Failed as a result of wrong positioning of the electrodes, local fibrosis, and the natural plasticity of the nervous system Complications: infection (2%) superficial wound dehiscence (10%) erosion of the extension cable towards the skin (1%) pain (10%) lead problem (38%) 3rd International Consultation on Incontinence, 2005 Parameters of ES Waveform Current intensity Ramping of impulses Pulse frequency On/Off timing Parameters of ES - - Aim to produce maximal painpain-free contraction perceptible by individual The intensity is increased according to one’ one’s tolerance 11 Parameters of ES Lower ranges (10(10-15Hz) has a calming effect on the detrusor muscle →inhibited bladder contractions used for those with urge UI; Higher ranges (50Hz)→ (50Hz)→optimum for urethral closure and builds strength used for those with stress UI Parameters of ES “On” On” and “Off” Off” timing - “On” On” time is the amount of time that the electrical current is delivered to the muscles “Off” Off” time is the amount of time when there is no electrical current to the muscle, allowing it to recover - Precaution of ES Apply stimulation not more than 30mins→ 30mins→muscle fatigue Observe for any signs of skin and mucosal irritation prior to use Observe any compliant of discomfort during and after the procedure Pressure Biofeedback Treatment of stress, urge and mixed incontinence A form of PFMs rehabilitation An electronic device made of an inflatable intravaginal or rectal probe Connected to a manometer Biofeedback is often used as an audiovisual instructional aid and method of evaluating progress 12 Pressure Biofeedback Help to control external sphincter by measuring the actions of the PFMs Feedback information to the person The information is stored, processed and fed back to the person in the form of sound, light or images Position: lying, standing, sitting Advantages of Biofeedback Contraindication of Pressure Biofeedback Allergic to natural rubber latex Client’ Client’s anatomy that make proper probe insertion difficult or impossible Any infection of the bladder or vagina or Symptoms of infection such as itching, dysuria, dysuria, sores or fever Pregnant or ? pregnant A useful tool for teaching a correct pelvic muscle contraction Can increase motivation and adherence Precautions of Pressure Biofeedback Examine any signs of skin and mucosal irritation prior to use Examine the product prior to use Examine any signs of deterioration such as tears, cuts or discoloration Examine any air leak of the latex balloon 13 Instructions for Pressure Probe The probe should be cleaned before & after Equalize the air pressure in the probe before use Insert the tip of the syringe into the oneone-way valve on the end of the probe tubing Remove the syringe and replace the plunger Instructions for Pressure Biofeedback Instructions for Pressure Biofeedback Hold the plunger firmly in this position Attach the probe to the appropriate port of the equipment When the ‘work’ work’ light is on, ask the client to squeeze pelvic floor muscles The light will give client feedback that she/he controls the correct muscles Spread a light coating of lubricating gel Insert the lubricated probe into the vagina or anus Inflate the probe by positioning the front edge of the rubber tip of the plunger at the appropriate mark vaginal probe: 15cc anal probe: 5cc Instructions for Pressure Biofeedback The force of the PFMs contractions is measured by the marking When the ‘rest’ light is ‘on’, ask client to relax the PFMs Client can adjust the PFE exercises pattern so that the exercises are performed correctly 14 Instructions for Pressure Biofeedback Following use, remove the probe from the port and deflate the probe Check the client any discomfort during and after the procedure Observe any skin or mucosal irritation after removal of probe Wash the probe with mild soap and water to remove any surface debris, and disinfect with Cidex for clinic use Absorbent products Do not use absorbent products instead of definitive interventions to decrease or eliminate urinary incontinence. Early dependency on absorbent pads may be a deterrent to achieving continence, providing the wearer a false sense of security. Chronic use of absorbent products may lead to inevitable acceptance of the incontinence condition, which removes the motivation to seek evaluation and treatment. In addition, improper use of absorbent products may contribute to skin breakdown and urinary tract infections. Thus, appropriate use, meticulous care, and frequent pad or garment changes are needed when absorbent products are used. External appliances: Condom catheter CC still has a role in controlling urinary incontinence in neurologic male patients (LOE 3) Long-term use may cause bacteriuria, but it does not increase the risk of UTI when compared to other methods of bladder management. (LOE 3) Complications may be less if applied properly with good hygiene care, frequently change of the CC and maintenance of low bladder pressures. (LOE 3) Special attention should be paid to people with dementia (LOE 3) Non-latex self-adhesive inflatable 3rd International Consultation on Incontinence, 2005 Latex Detachable tip For retracted penis 15 External appliances: Condom catheter 60 SCI using condom catheter >50% positive urine culture In which 56% tissue invasion by bacteria (Newman & Price 1985) Incomplete emptying High RU Bladder overdistension Urine stasis inside condom catheter Urine leakage External appliances: Condom catheter Complications If skin lesion Remove CC, resume IC / urethral catheter Till skin is dry & healed, to reapply CC Allergic dermatitis Remove CC, topical steroid (Harmon et al 1995) External appliances: Condom catheter Penetrating / non-penetrating lesions Due to fastener or proximal hard roller ring Compressive effect (Nanninga & Rosen 1975) Chronic dermatitis Irritative or allergic reaction SCI patient w/ bil hydronephrosis due to condom catheter fasten strap Resolved when the strap is removed (Pidde &Little, 1994) External appliances : Condom catheter Recommendations (All grades of recommendation: B/C) To have better control of leakage, a more secure CC should be used, and patients should be educated and cooperative. To prevent latex allergy, a silicone CC should be used and serological examination of latex-specific IGE is recommended in addition to patient history to better identify patients at risk. To prevent compressive effects, choose proper size CC with self- adhesive. To prevent infection, a daily change of the CC could help. To prevent bladder and upper tract damage, regular bladder emptying with low bladder pressures and low post void residual should be persued. 3rd International Consultation on Incontinence, 2005 16 Penile Compression Devices and absorbent products External appliances Penile Compression Devices Cunningham clamp Continence penile cuff Cunningham clamp skin care products continence penile cuff drip collector Overflow urinary incontinence Bladder pressure overcomes urethral pressure only at very high bladder volume Diabetes cystopathy CROU BPH, urethral stricture, detrusor-sphincter dyssynergia Significant PVR leading to overflow incontinence, UTI, urinary tract stone formation, bladder diverticulum obstructive uropathy BPH potential complications 17 Two routes of urinary catheterisation Urethral 18 Indwelling transurethral catheter Complications Alteration of body image Feeling of dependence Pain & discomfort Bacterial biofilm, UTI acute & chronic Encrustation, blockage, bladder & renal stone Infection: para-urethral abscess, urethritis, prostatitis, epididymo-orchitis, cystitis Urethral trauma & bleeding, fistula, urethral stricture Two routes of urinary catheterisation Suprapubic Catheter-associated UTI (CAUTI) Indwelling transurethral catheter Complications Catheter induced detrusor spasm, urine bypass, catheter expulsion Urethral sphincter erosion Bladder neck incompetence Balloon deflation problem, problematic removal Balloon self-deflation Bladder carcinoma 100%-silicon catheter balloon cuffing Anaphylaxis & allergy • 10-15 % of all hospitalised patients have indwelling urethral catheters Stamm, 1975 Fincke & Friedland, 1976 • ~ 40 % of all hospital-acquired infections occur in the urinary tract Stamm, 1975 19 Catheter-associated UTI Incidence Single sterile catheterisation • Healthy outpatients • Hospitalised patients Male Female 0.5 – 1 % Bacterial biofilms part bacterial matter and part crystals 5% 10 – 20 % Longer duration of catheterisation 5 % per day AUA Update Series 21:292, 2002 2 hrs primary adherence of bacteria on 100%Silicon Foley Bacterial Biofilm (18 hrs later) on 100%-Silicon Foley Bacterial biofilms Stickler, D., Ganderton, L., King.

It is neither stress dependent (due to exertion) nor due to bladder dysfunction (Wille et al, 2000) should be distinguished from terminal dribble, which occurs at the end of micturition (Shah, 1994). The condition can be a nuisance and cause embarrassment. Post-micturition dribble Aetiology failure of the bulbocavernosus muscle (which circles the bulbar urethra) to contract by reflex action after micturition and to evacuate urine from this portion of the urethra (Feneley, 1986) This reflex is known as the urethrocavernosus reflex (Shafik and El-Sibai, 2000). Its failure may occur as a result of surgery, neurological conditions or weak pelvic floor muscles. Urine remaining in the bulbar portion of the urethra will then dribble out on movement. 24 Treatment for Post-micturition dribble Paterson et al (1997) conducted a single-blind randomised controlled trial comparing pelvic floor muscle exercises with bulbar urethral massage (urethral milking). 49 men (36-83 years) not undergone surgery on the bladder, urethra or prostate gland RCT: pelvic muscle exercise, urethral milking or counselling followed up the treatment specific to their group for 12 weeks. At 5, 9 and 13 weeks, urine loss was assessed PATERSON J, PINNOCK CB, MARSHALL VR. Pelvic floor exercises as a treatment for postmicturition dribble. British Journal of Urology 1997; 79(6) pp 892-897. Treatment for Post-micturition dribble Urethral milking: after urinating, to place his fingers behind the scrotum and gently massage the bulbar urethra in a forwards and upwards direction in order to ‘milk’ the remaining urine from the urethra They found that men who practised pelvic floor exercises were almost twice as likely to have reduced urine loss than the urethral milking group and both these interventions were more effective than counselling alone.

What will be expected after the surgery? DOs and DON’Ts after implant surgery Initially GSI may be improved transiently to a certain degree because of operated site swelling which narrows the urethra Gently pull down AUS pump once each day to prevent upward migration during the capsule-forming period As swelling gradually subside, return of GSI is anticipated Wear loose-fitting clothing and undergarments Don’t be panic, because the AUS is not yet activated until the operated site is healed Avoids prolonged sitting, it may put unnecessary pressure on the perineum where the cuff is placed The AUS will be activated by a Urologist or Urology Nurse If scrotum is swelling, ice therapy and scrotal support may help Then you will be taught how to cycle the AUS Instruct patient not to manipulate the AUS for 6 weeks until activation is permitted Avoid constipation to prevent straining, more roughage and water intake, stool softener may be prescribed 27 When will the AUS be started working ?

Special things to do following AUS Activation is accomplished by a firm and sustained squeeze of the pump, allowing the deactivation pin to "pop" into the activated position. If inadvertently locks the button when the cuff is closed, urinary retention occurs Conversely, if the button is locked when the cuff is open, persistent incontinence occurs Patients should be instructed on the locking mechanism to understand and be able to respond to these problems Special things to do following AUS As with any prosthetic implantation, patients should take prophylactic antibiotics prior to dental or surgical procedures to avoid hematogenous seeding Smith, J.J., & Barrett, D.M, (2002).
