Effective Mnemonics for Urologic Providers
The most clinically validated mnemonic for urologic practice is the systematic approach to hematuria evaluation using risk stratification criteria, while general ICU-based mnemonics like FASTHUG-MAIDENS have proven utility for medication-related assessments but lack urology-specific validation.
Hematuria Evaluation Mnemonic: The "3-R" Approach
The most evidence-based systematic approach for urologic providers involves Risk stratification, Rule-out benign causes, and Repeat confirmation 1, 2:
Risk Stratification Framework
High-Risk Criteria (requires immediate cystoscopy and imaging) 1:
- Age ≥60 years
- Smoking history >30 pack-years
25 RBC/HPF on urinalysis
- History of gross hematuria
- Occupational exposure to benzenes or aromatic amines
Intermediate-Risk Criteria (shared decision-making for cystoscopy) 1:
- Women age 50-59 or men age 40-59 years
- 10-30 pack-years smoking history
- 11-25 RBC/HPF on single urinalysis
Low-Risk Criteria (may defer immediate invasive evaluation) 1:
- Women <50 years or men <40 years
- Never smoker or <10 pack-years
- 3-10 RBC/HPF on single urinalysis
Rule-Out Benign Causes Systematically
The "MIST" approach for benign hematuria causes 1:
- Menstruation - repeat UA 48 hours after cessation
- Infection - obtain urine culture, treat, repeat UA at 6 weeks
- Sexual activity/trauma - consider as transient cause
- Trauma/exercise - repeat UA 48 hours after cessation
Repeat Confirmation Protocol
Critical timing for follow-up 1, 2:
- Post-UTI treatment: repeat UA at 6 weeks (not earlier - this is a critical safety checkpoint as ~3% harbor malignancy)
- Persistent hematuria after negative workup: repeat UA at 6,12,24, and 36 months
- Comprehensive re-evaluation at 3-5 years if hematuria persists
Catheter-Associated Hematuria: The "DRIP" Mnemonic
For managing catheter-related bleeding 2:
Drainage assessment - ensure catheter patency, consider replacement with appropriate size (14-16 Fr) 2
Rule out trauma - assess for urethral injury signs (blood at meatus, difficult passage, perineal ecchymosis); perform retrograde urethrography before re-attempting if suspected 2
Infection evaluation - obtain urine culture before antibiotics; catheter-associated UTI is the fourth leading cause of hospital-acquired infections 2
Pelvic trauma consideration - if gross hematuria with pelvic fracture, 29% have bladder rupture requiring retrograde cystography 2
Overactive Bladder Assessment: The "DIAPER" Framework
Based on AUA/SUFU guidelines for systematic OAB evaluation 3:
Duration and baseline symptoms - document timeline and severity 3
Indications review - assess current medications that may cause symptoms 3
Abdominal and pelvic exam - include rectal/GU exam and lower extremity edema assessment 3
Post-void residual - measure in patients with obstructive symptoms, neurologic diagnoses, or history of surgery (use caution with antimuscarinics if PVR 250-300 mL) 3
Exclude other conditions - perform urinalysis to rule out UTI and hematuria; refer if hematuria present 3
Review cognitive function - assess ability to dress independently as indicator of toileting capability 3
Antimicrobial Prophylaxis: The "STOP" Principle
From AUA Best Practice Statement 3:
Single-dose only - AP recommended for most urologic cases, not beyond case completion 3
Timing critical - ensure minimum inhibitory concentrations at procedure time; may require re-dosing for long cases 3
Organism-directed - select antimicrobial based on surgical site and likely pathogens 3
Prevent resistance - use lowest effective dose; systemic antimicrobial usage is primary driver of resistance 3
Urologic Infection Management: The "CATS" Approach
Based on EAU guidelines 3:
Culture before treatment - perform validated NAAT on first-void urine or urethral smear for urethritis; urethral swab culture for gonorrhea resistance profiling 3
Assess for sepsis - use SOFA or qSOFA scoring; obtain two sets of blood cultures and drainage fluids 3
Treat pathogen-directed - use local resistance data; sexual partners require treatment 3
Source control - relieve obstruction and drain abscesses in urosepsis; collaborative care with ICU and infectious disease 3
Common Pitfalls to Avoid
Never attribute hematuria solely to anticoagulation - evaluate identically regardless of anticoagulation status 1, 2
Never delay post-UTI follow-up - the 6-week repeat UA is mandatory, not optional, as delayed cancer diagnosis can occur 1
Never perform inadequate cystography - clamping Foley and allowing IV contrast accumulation misses bladder injuries 2
Never use prophylactic antimicrobials routinely - do not use to prevent catheter-associated UTI or after catheter removal 3
Never extend antimicrobial prophylaxis beyond case completion - single-dose is sufficient for most procedures 3
