1 Basic Urology for Primary Care Providers Getting Yourself and Your Patients Beyond ”Please Hold” Michael Jacobson MD PhD 2/12/12

2 My Contact Information (Preferred!!) Pager (510) Phone (510)

3 Overview/Goals Urology Referrals How to approach the most common problems Providing a useful workup when consulting Improved collaboration Topics BPH & Urine Retention Hematuria Incontinence Infections of the urinary tract Elevated PSA Stones

4 Background The Long Wait Nonurgent urology consult 8-9 months Cancer 6-8 weeks consult weeks surgery Obstructive stones 6-8 weeks +12 weeks surgery patients scheduled each clinic

5 Benign Prostatic Hypertrophy 50% men > 60 yo 90% men > 80 yo Nonmalignant, uncontrolled prostatic growth Bladder Outlet Obstruction Lower urinary tract sx (LUTS) Obstructive Irritative Hematuria

6 LUTS Obstructive Weak stream Intermittency Hesitancy Incomplete voiding Postvoid dribbling Straining to void Valsalva Irritative Frequency Urgency Nocturia Dysuria

7 LUTS Differential Diagnosis BPH UTI Primary bladder dysfunction (MS, neurogenic bladder, DM) Prostatitis/chronic pelvic pain Urethral stricture Stones Prostate cancer, Bladder cancer

8 Helpful tip: Men older than 60 who have LUTS USUALLY have BPH Men younger than 50 who have LUTS ALMOST NEVER have BPH

9

10 Initial Workup 1.Digital Rectal Exam 2.UA 3.PSA (> 10 years life expectancy) 4.Post void residual (Ultrasound or bladder scanner) Normal < 100 mL Over 100 mL: BPH should be treated Goal of therapy: PVR < 100 AUA symptom score

11 Treatment options for BPH Surveillance with general measures AUA SS < 8 Yearly re-evaluation with “initial workup” Medications Herbal Alpha blockers 5 alpha reductase inhibitors Surgical Minimally invasive TURP Simple prostatectomy

12 General Measures Avoid substances that make symptoms worse Alpha agonists Decongestants with pseudoephedrine Ephedra Caffeine and EtOH Spicy and acidic foods Reduce nocturia: Decrease fluids in the evening Avoid diuretics in the evening LE edema: elevate legs one hour before bed

13 Medications Alpha blockers Works over days Relaxes smooth muscle in urethra 5-alpha reductase inhibitors Shrinks the prostate Good for bleeding Prevents/treats obstruction PSA drops by 50% Side effects: sexual, gynecomastica Works over months

14 Alpha Blockade Alpha-1 blockers (postural hypotension): Terazosin (eff dose: 10 mg qhs) Doxazosin (eff dose: 8 mg qhs) *Always titrate alpha-1 blockers to avoid hypotension/syncope. Alpha 1-a blocker Tamsulosin—Flomax (eff dose mg 30 min qAC) *No need to titrate I recommend tamsulosin for patients in urinary retention

15 Surgical Therapy Strong indications Refractory urinary retention Recurrent UTIs Refractory gross hematuria Bladder stones Renal insufficiency Moderate indications AUA SS > 8 and Substantial bother Increasing PVR

16 Urinary Retention Pre-existing partial obstruction (e.g. BPH) Sudden increased outlet resistance or decreased detrusor pressure Precipitating event: Infection Bleeding Overdistention

17 Treatment Gross hematuria (clot retention, bladder decompression bleeding), Renal failure, febrile UTI Admission to hospital through ER Most patients Foley Catheter for 10 days Start alpha blocker Patients in complete retention Start 5 alpha reductase inhibitor

18 Referral AUA SS What medications, doses and how long Cr PVR Infections, urinary retention or gross hematuria

19 Hematuria Differential Diagnosis Cancer (painless) Bladder, Kidney, Prostate Infection Stones BPH Trauma Medications/toxins Benign/idiopathic

20 Hematuria Many benign causes, some malignant We don’t want to miss cancer Urgent: Passing clots, can’t void Blood loss anemia (rare) Not urgent: Able to void Normal H/H, normal Cr

21 Gross vs Microhematuria Gross Pink Lemonade Cool Aid Red Wine Motor Oil Ketchup Microhematuria > 5 RBC per High Power Field At least 2 separate Uas Need microscopic, dipstick not enough! Not explained by infection

22 Workup—Gross Hematuria Workup UA/Cx (nitrite positive?) CBC Chem7 CT urogram (3 phase scan with IV contrast) Follow-up for cystoscopy When to send to ER Dropping H/H Unrelenting Clot retention

23 Microscopic hematuria workup Urine culture, UA with micro x 2, CBC, chem 7 Upper tract imaging: CT IVP (with delayed phase) Referral for cystoscopy (last part of the workup) For patients with elevated creatinine, refer without CT scan retrograde pyelogram in the OR u/s or noncon might be helpful

24 CT IVP (CT Urogram) 3 phases: 1.Noncontrast Abdomen/Pelvis Shows stones 2.Arterial Phase Shows vascular tumors (kidneys) 3.Delayed phase Opacifies urinary tract Shows filling defects (possible tumors) CT IVP does not adequately evaluate the bladder!!

25 Filling Defects

26 Cystoscopy-tumors

27 Incontinence Stress urinary incontinence Increase in abdominal pressure Coughing Sneezing Straining Lifting Bending Exercising/exertion Urge urinary incontinence Accompanied by urge Mixed incontinence Both stress and urge Continuous incontinence e.g. secondary to fistula Overflow incontinence Associated with poor emptying

28 Transient Urinary Incontinence “DIAPPERS” Delirium Infection Atrophic vaginitis Pharmaceuticals/polypharm Psychological (esp. depression) Excessive production (diuretics, DM) Restricted Mobility (PD, arthritis) Stool impaction/Constipation

29 “Urologic Incontinence”

30 What you can try for urge incontinence first Anticholinergic medications Ditropan 5 mg po TID or Ditropan XR 10 mg po daily Urinary retention Dry mouth, dry eyes, constipation Delirium Vesicare, Detrol, etc For post menopausal women with no history of breast or GYN cancer: Vaginal Premarin or Estrace cream Pea size daily x 4 weeks then 2x per week

31 Evaluation/include on referral: History Precipitating factors Severity: # pads per day, how wet Obstructive/irritative sx OB history Previous GU conditions Previous pelvic surgery Neurologic disease Fluid consumption Medications

32 Physical exam Pelvic exam on women Check for atrophic vaginitis Obvious prolapse Cough test Rectal exam Stool impaction, sphincter tone Lower extremities Edema can cause excess urine production at night Neurological Perineal sensation, anal sphincter tone Bulbocavernosus reflex

33 Infections Frequent urinary tract infections Epididymitis Orchitis Prostatitis

34 Frequent UTIs Men: Think BPH or chronic bacterial prostatitis Young women: Think Constipation, sexual activity Postmenopausal women: Think atrophic vaginitis or constipation or both

35 Relapsing UTI classification Bacterial persistence versus re-infection Bacterial persistence: Antibiotics eradicate bacteria from the urine temporarily Often associated with foreign body or stone Urine culture showing the same bacteria repeatedly Evaluation Urine culture prior to each treatment with appropriate abx Renal/bladder u/s plus KUB (Stones? PVR? Hydro?) Check blood sugar

36 Treatment Women with afebrile UTIs 3 days antibiotics Check urine culture before starting empiric treatment Men days of abx Check urine culture before starting empiric treatment

37 Epididymo-Orchitis Presentation Testicular pain (Ddx: testicular torsion) Sudden onset of intense pain  Torsion Gradual onset  epididymo-orchitis Associated with STD: with urethritis and urethral discharge May be associated with UTI Swelling/tenderness of testis, epididymis and/or cord +/- scrotal erythema or edema +/- fever +/- hydrocele ALL PATIENTS REQUIRE A SCROTAL ULTRASOUND

38 Epididymo-Orchitis--Treatment Infectious Men < 35 years old: STD (Neisseria gonorrhoeae and Chlamydia trachomatis) Treat with Rocephin 250 mg IM single dose + Doxycycline 100 mg po BID x 10 days Check urine culture first Check urethral swab or GC urine test first Men > 35 years old: most common E. coli Initial treatment: Levofloxacin x 10 days Adjust according to urine culture Pain/fever usually improve after 3 days. Induration may take weeks/months If symptoms return then treat up to 6 weeks with antibiotics

39 Prostatitis Most commonly: NONBACTERIAL Chronic prostate syndromes: Pain GU pain, back pain, suprapubic pain, perineal pain, dysuria, frequency, urgency, painful ejaculation Acute Bacterial Prostatitis Usually diagnosed in YOUNG MEN Most common: E.coli Fever, irritative/obstructive voiding sx, extremely tender and warm/boggy prostate

40 Prostatitis--continued Chronic Bacterial Prostatitis Recurrent, symptomatic infection GU pain, back pain, suprapubic pain, perineal pain, dysuria, frequency/urgency, painful ejaculation Usually diagnosed in OLDER MEN Most common organism: E.Coli Associated with prostatic calculi (nidus) Most common cause of recurrent UTIs in adult males

41 Treatment Acute prostatitis Emergency room—especially if with high fever Will need 4-6 weeks of post hospitalization antibiotics If not hospitalized, get urine culture and start a fluoroquinolone Consider tylenol, stool softeners, analgesics Chronic prostatitis 8-16 weeks of initial antibiotic therapy Reculture if symptoms return or persists Recurrent: 6 months suppressive abx

42 Nonbacterial Prostatitis Treatment: Empiric 6-8 week course of TMP-SMX or fluoroquinolone If no response then doxycycline 100 mg po bid for 4-6 weeks If no response then no further antibiotic treatment Consider alpha blockade Stress reduction/meditation Diet improvement Diazepam (pelvic floor relaxation) Pelvic PT for pelvic floor relaxation) Pain specialist

43 Prostate Cancer Screening

44 PSA and DRE Increase in detection Stage shift Prior to screening: CaP detected when caused local symptoms or mets Now: > 90% CaP detected when potentially curable Asymptomatic Prostate Cancer Screening and Diagnosis

45 Prostate cancer--Epidemiology

46 Annual PSA and DRE In men with > 10 years life expectancy: Start for high risk of CaP Start 50 other men >70 if healthy with >10 years life expectancy Prior to testing, discuss benefits and limitations of CaP detection and treatment Screening Recommendations (AUA, NCCN, ACS)

47 Digital Rectal Exam Abnormal DRE CaP diagnosis in 15%-25% Normal DRE (age matched) <5% cancer prevalence Not accurate or sensitive But abn DRE with elevated PSA: 5x increased risk of CaP

48 PSA—Prostate Specific Antigen Serum protease produced only in prostate epithelium Causes semen to become less viscous Increase in serum PSA Prostate cancer Prostatitis or UTI BPH Urinary retention Ejaculation Catheterization

49 “Normal” based on age 40’s: less than 1 ng/dL 50’s: less than ’s: less than 4 My criteria for prostate biopsy 40’s: >1 and increasing by 0.3/year 50’s: > 2.5 and/or increasing by 0.3/year 60’s: > 4. If > 4 increasing by 0.7/year, if <4 increasing by 0.3/year Any abnormal DRE Serum PSA levels

50 Stones

51 Flank Pain Workup History: Previous stones? Diabetic? Length/severity of sx? Fevers? Severe n/v? Labs: WBC sCr UA: nitrites? Exam Febrile? Helped with narcotics/antiemetics? Imaging Hydro? (obstructive?) 2 kidneys?

52 Urolithiasis Absolute reasons for admission/immediate tx: Obstructed pyelonephritis Increasing renal insufficiency (e.g. Solitary kidney, bilateral stones) Unrelenting pain or nausea/vomiting

53 Imaging Gold standard: Noncontrast CT scan Radiation, expensive, in-demand resource Ultrasound? Quick, available, no radiation Not very sensitive for hydro Miss small stones Cannot be used to plan surgical treatment KUB Quick, inexpensive, lower radiation dose Problems: radiolucent stones, stool/poor sensitivity

54 Immediate referral for drainage Sepsis Fever with UTI (and stone) or elevated WBC Creatinine 0.5 higher than baseline Solitary kidney (or functionally solitary) (Uncontrollable pain or vomiting) Beware of the diabetic patient with UTI + stone May have few sx

55 The passable stone 90% 4-6 mm: 70-80% 6-8 mm: 50-60% 8-10 mm: ~30% >10 mm: unlikely Assuming 6 weeks, with Flomax
