(Paralyzed Veterans of America) SCI: A Manual for Healthy Living (TIRR) Urinary Tract Infections (RTC/IL & PVA) Bladder Management: What You Should Know (by the Consortium for Spinal Cord Medicine) Presentation Review • Define urinary tract infections (UTI) • Identify who is at risk? • Causes of Urinary Tract Infections • Signs and Symptoms of UTI • Testing and diagnosing UTIs • Methods to empty your bladder • UTI prevention techniques and treatment Urinary Tract Infections A Major Problem • What are Urinary Tract Infections? – Urinary Tract Infections or UTIs are caused when bacteria is introduced into the urinary tract system. This may be caused by contamination of catheter equipment, and may be more likely to occur when the individual has poor hygiene, low fluid intake, or infrequent urination. Urinary Tract Infections (UTI) • Significance of the problem – Most common complication with spinal cord injury – Biggest threat to health and survival – Most common hospital acquired infection • Often due to indwelling catheters How the Urinary System Works… • Normal urinary system – Sterile, little or no bacteria – Kidney filters waste and excess water from blood, becomes urine – Urine carried by ureters (narrow tubes) to the bladder – The bladder then holds the urine How the Urinary System Works… • Bladder signals brain when full • Brain signals via the spinal cord system to the bladder to contract and open • Urine is retained by sphincters that relax to empty What Is a UTI? • After a spinal cord injury: – Signals from the brain are unable to communicate with the bladder – The bladder may overflow or void involuntarily – Or, it may not empty completely – Individuals may have more frequent urination Who Is at Risk for UTIs? • People with: – Spinal cord injuries – Urinary catheters – Diabetes – Enlarged prostate – Who are older – Who have had frequent previous UTIs • People who have difficulty urinating • Affects more women than men – 1 out of 5 women (http://kidney.niddk.nih.Gov/kudiseases/pubs/utiadult/index.htm) What are Causes of UTI • High bacteria counts • Colonies of bacteria multiply rapidly • Microorganisms cling to the urethra (urine pathway between bladder and outside of body) • Can be caused from contamination with feces coming in contact with the catheter http://kidney.niddk.nih.gov/kudiseases/pubs/utiadult/index.htm Causes of UTI • Intermittent catheterization – Catheter inserted in urethra may pick up outside bacteria – Bacteria pushed into bladder – Bacteria quickly multiplies if bladder is not emptied of urine within 4-6 hours Types of intermittent catheters Causes of UTI • Indwelling catheter – Catheter gives bacteria direct path to bladder – Bacteria can develop into UTI if: • Catheter blocked • Decreased resistance to infection • Concentrated urine, not enough fluids • If the urine in the bladder is not kept acidic enough (many drink cranberry juice to keep the bladder acidic). Causes of UTI • Without prompt treatment bacteria can move from bladder to ureters (small tubes) and infect kidneys • Can cause Pyelonephritis = kidney infection – Caused by backflow of urine into ureters and kidneys – Occurs less often than bladder infections – If kidneys are damaged because of repeated infections, people may require dialysis – Can cause death in severe cases Causes of UTI • For women – When toileting wipe front to back • Should wipe: FRONT TO BACK – Sexual intercourse • Outside bacteria pushed into uterus during intercourse – Birth control methods • Diaphragms or spermicide lubricates/condoms can increase bacteria growth http://kidney.niddk.nih.gov/kudiseases/pubs/uti_ez/index.htm Signs and Symptoms of UTI • Burning of urethra, penis or pubic area when urinating • Mild, low back pain or other aches • Fever or chills • Frequent urge to urinate • Feeling the need to catheterize often or immediately www.sci-info-pages.com/uti.html Signs and Symptoms of UTI • Headache • Fever • Confusion • Nausea • Feeling lousy or tired • Leakage • Increased spasms of leg, abdomen, or bladder • NOTE: UTI symptoms are often masked in individuals with SCI. Signs and Symptoms of UTI • What to look for in urine – Sediment • Gritty material – Mucus – Cloudy Urine – Concentrated appearance – Blood • Pink or red urine – Foul smelling odor Testing for UTI • Urine culture – Sample of urine – Excess bacteria or infection – Sensitivity testing • Find correct antibiotic Testing for UTI • Urinalysis – Urine sample – Chemical and cell make-up Diagnosing UTI Causes • Urodynamics – Series of observations – Analyze urinary system and how it empties – May recommend bladder management program Diagnosing UTI Causes • Cystourethrogram – X-ray • Inject dye into bladder • Reveals size/shape of bladder – Reflux tested • Pressure pushes urine in kidneys to determine resistance to reflux Diagnosing UTI Causes • Cystometrogram – Fill bladder with carbon dioxide or water • Simulates full bladder • Measures amount of pressure and if bladder is spastic or flaccid • Determines whether the bladder can contain small versus large amounts of urine • determines the volume point at which urine is likely to “spill over” Diagnosing UTI Causes • Cystoscopy – See urethra and bladder – Prism in cystoscope reflects light – Helps determine if there are bladder stones or calculi in the bladder that can cause recurrent infections Diagnosing UTI Causes • Renal scan – Radioactive material injected in bloodstream – Patient drinks several glasses of water – Measures • Blood supply to kidneys • How each kidney is functioning for the production of urine Diagnosing UTI Causes • Ultrasound – Uses sound waves • Bounce off organs – Creates a picture of urinary organs – Detects tumors, cysts, and stones Artificial Emptying • Once the pathway between the brain and bladder is interrupted, a person cannot voluntarily empty or control his bladder. Instead he must use different techniques: – – – – – – Intermittent catheterization Indwelling catheter Condom or external catheter Suprapubic catheter Urinary ileostomy or ileal conduit Sphincterotomy – Tapping – Crede Artificial Emptying • Intermittent catheterization – Tube inserted into bladder for drainage – Routine emptying usually 3-4 times daily • Catheter volume should be kept below 500 mL Artificial Emptying Intermittent catheterization (continued) • Sterile technique • May be better for older persons and those with impaired immune systems • Non-sterile “clean” • Clean intermittent catheterization (CIC) • Developed because hard to accomplish true sterile catheters in normal environment • Produces similar results to sterile technique Artificial Emptying • Indwelling catheter or Foley catheter – Inserted and left in bladder – Balloon deflated and catheter is changed every 2-4 weeks – Collection device required • Leg bag Artificial Emptying • Condom or external catheter – Males only – Condom for reflex voiding • Empty voluntarily – External catheter for spontaneous emptying of urine Artificial Emptying • Condom or external catheter (continued) – Materials • Latex rubber • Polyvinyl • Silicone – Attached by • Double-sided adhesive • Latex inflatable cuff • Foam strap Artificial Emptying • Suprapubic – Opening created in abdomen and bladder – Catheter placed in bladder through incision Artificial Emptying • Suprapubic (continued) – Inserted in bladder surgically by doctor – Changed every 2-4 weeks – More comfortable – Less chance to fall out or leak – Preferable and more convenient than indwelling catheter – User are just as vulnerable to UTIs Artificial Emptying • Surgery – Urinary ileostomy or ileal conduit • New urinary pathway formed using part of small intestine – Sphincterotomy • Sphincter cut • Outlet from bladder no longer has tight pressure Other Voiding Methods • Artificial stimulation – “Tapping” • Tap abdomen over bladder • Usually best with spastic bladder • Causes bladder muscles to contract and void – Crede’ • Push on abdomen to squeeze urine out • Usually best with flaccid bladder RISKS Associated with Catheters • Intermittent catheterization – Swelling of urethra – Strictures or narrowing of uretha from scar tissue – False passages – Kidney damage Risks Associated with Catheters • Indwelling Catheter – Strictures • Narrowing of urethra from scar tissue – Erosion of urethra, requiring larger catheter – Shrinkage of bladder – Bladder walls more rigid – Increased mortality and risk of bladder cancer Risks Associated with Catheters • Indwelling catheter (continued) – External collection bag • Ideal place for bacteria growth or infection • Bacteria or infection can spread up catheter to bladder, kidneys, and blood stream – Maintaining collection system as a closed and sterile environment • Outside of catheter can still breed bacteria and infect bladder Risks Associated with Catheters • External or Condom Catheter – Problems result from improper or prolonged use – Chance of infection – Less than internal catheters – Skin irritation • Friction from catheter • Prolonged moisture against skin • Adhesives or pressure straps to hold catheter in place Risks Associated with Catheters • External or condom catheter (continued) – Older men • Penis may have retracted • Difficult to keep catheter secure on penis – Careful attention to avoid: • Skin rash • Maceration of penis = softening of penis tissue • Ischemia (loss of blood flow in the penis) • Penile obstruction Risks Associated With Catheters • Suprapubic – At time of insertion • Swelling at insertion site • Bleeding • Bowel injury – Management problems • Uncontrolled urine leakage • Skin erosion • Catheter reinsertion problems Common Catheter Problems • Burning or spasms – When urine passes through catheter – Common and normal – May cause leakage or indicate needed catheter change • Falling out or accidentally pulled out – Accidentally pulled out or falls out from excessive tension or bladder spasms • Blockage or obstruction – Formation of encrustations of calculi Common Catheter Problems • Catheter leakage – Frequently occurs – Results from • Bladder spasms • Infection • Catheter or balloon excessive in size • Irritated bladder • Catheter infection – Development of bacteria in urine Causes of Pressure Build up • Indwelling catheter – Blocked or kinked • Intermittent catheterization – Wait too long for catheter insertion • External catheter – Sphincter doesn’t relax – Autonomic Dysreflexia – Kinked catheter or un-emptied leg bag Selecting A Urinary Management Program • Should be based on individual need, injury level, and lifestyle • Should look at long term versus short term • Primary goal – Achieving low pressure filling and complete emptying When to Change Urinary Program or See a Doctor • Fever (temperature above 100o F.) • Symptoms interfering with life • Acute urinary infection – 2 episodes in 6 months Personal Assistant Precautions • Wash hands thoroughly before and after catheterization and emptying drainage bag • Wear rubber or latex gloves for procedure • Disconnecting indwelling catheters dangerous (keep system closed and sterile as possible) Preventing Odor • Good hygiene – Use plenty of warm water and soap to wash your skin – Wash clothing and wheelchair cushion after spills • Protective waterproof pads • Cold water for rubber catheter or drainage bag • Avoid carbonated beverages Prevention Techniques • Drink plenty of fluids – Helps flush bacteria out – Water is best choice (6-8 glasses per day) • Urinate frequently – If urine is in bladder too long, bacteria quickly grow and multiply Prevention Techniques • Wear loose fitting clothes and cotton underwear – Helps keep area dry and free of moisture • Always wipe front to back Prevention Techniques • For women – Cleanse genitals before sexual intercourse – Urinate after sexual intercourse • Can help flush out any bacteria that entered the urethra – Using lubricated condoms without spermicide or a spermicidal lubricant – Showers not baths – Avoid scented hygiene douche or sprays – take a probiotic supplement to maintain proper vaginal flora http://kidney.niddk.nih.gov/kudiseases/pubs/utiadult/index.htm Prevention Techniques • Follow management program • Practice doctor recommendations • Sterile catheterization • Regular washing or frequent replacement of catheters Prevention Techniques • Intermittent catheterization – If notice UTI warning signs • Catheterize self more often to reduce bacteria • Increase fluid intake • Wash hands thoroughly with soap and warm water before handling the catheter and other equipment Prevention Techniques • Indwelling catheters – Drink plenty of fluids, most important • Urine clear and almost colorless – Change catheter once a week up to one month • More if there is increased build-up on the catheter Prevention Techniques • Indwelling catheters (continued) – Alternative methods for catheterization recommended • Can cause bladder infections, damage to urethra, increased risk for bladder cancer, and increased mortality • Intermittent catheterization or other forms of catheterization recommended http://www.tis-group.org/no_cath.html Prevention Techniques • Condom or external catheters – Changed daily – Use soap and warm water to clean perineal area – Air dry penile area • Suprapubic – Keep ostomy area shaved and clean Treatment • Antibiotics – Depends on patient history and results of the bacteria culture – Take pills 7 to 10 days as prescribed by health professional to ensure infection is gone – For repeat infections, therapy may be longer and may include intravenous medications – Treatment for men may be longer • Bacteria can hide in the prostate tissue http://kidney.niddk.nih.gov/kudiseases/pubs/utiadult/index.htm Treatment • Relieving pain of a UTI – Pain medication – Heating pads may aid in discomfort • Drink plenty of water – Flush out bacteria • Avoid coffee, spicy foods, and caffeine • Quit smoking – Major known cause of bladder cancer Fungal UTIs • Some UTIs are caused by fungi of the genus Candida • Treatment is antifungal drugs such as fuconazole • Prevention includes treatment of vaginal yeast infections Review of Today’s Session Today we: • Defined urinary tract infections
