Patient inputs (21)

Pediatric post-hypospadias repair stricture pathway differs from adult bulbar / penile / pan-urethral (AUA 2017)

Bulbar (straddle injury) vs membranous PFUI (pelvic fracture) — phenotype + repair timing (AUA 2017)

Post-TURP, post-catheter, post-prostatectomy bladder-neck contracture differential; influences segment + treatment choice (AUA 2017)

White plaques / phimosis / meatal scarring → LSA; topical clobetasol first-line; pan-urethral if extensive (AUA 2017)

Recurrent stricture after first DVIU has diminishing return — urethroplasty preferred over repeat DVIU (AUA 2017)

Anticholinergics + decongestants worsen voiding; α-blocker trial may bridge symptoms; coumadin / DOAC affects surgical planning (AUA 2017)

Obstructive predominant (weak stream / spraying / hesitancy / straining / dribbling) — differentiate from BPH (older patient) and overactive bladder (storage predominant) (AUA 2017)

AUA scope is male urethral stricture; female urethral stricture is rare and out of scope here (route urogyn)

RUG — gold-standard imaging to define stricture location, length, complexity; mandatory for surgical planning (AUA 2017)

Qmax <15 mL/s consistent with obstruction; plateau / bell-shaped curve interpretation; serial monitoring (AUA 2017)

Elevated PVR (>100 mL) — clinically significant obstruction; gates AUR risk (AUA 2017)

Rule UTI before any instrumentation; treat infection before DVIU / urethroplasty (AUA 2017)

Baseline renal function; obstructive nephropathy if bilateral; pre-op clearance (AUA 2017)

AUR with palpable bladder → STAT decompression (suprapubic if Foley-impassable); route uro.acute-urinary-retention.v1

Fever + obstruction → urosepsis pathway; STAT decompression + IV abx (uro.uti.complicated.v1)

Severity stratification — IPSS 0–35; ≥20 severe; gates intervention urgency (AUA 2017)

Chronic gonorrhoeal / chlamydial urethritis — inflammatory bulbar stricture phenotype; rare today with treatment but still relevant (CDC STI 2021)

Post-radiation stricture — challenging surgical bed; preferentially endoscopic management when possible (AUA 2017)

Post-hypospadias-repair stricture is a pediatric uro subspecialty pathway (AUA 2017)

VCUG complementary — antegrade view especially for bladder-neck contracture and proximal stricture (AUA 2017)

Cystoscopy — visual confirmation, calibre measurement, biopsy for LSA confirmation if atypical (AUA 2017)

Recommended regimen

AUA 2017 — dilation → DVIU (first / short bulbar) → urethroplasty (definitive — anastomotic / substitution / flap) + LSA topical clobetasol + bladder-neck-contracture endoscopic + pediatric peds-uro
axis: urethral_stricture_intervention_ladderstep 1 - STEP 1 — Urethral dilation (first presentation / short stricture; low durability)
Selected step "STEP 1 — Urethral dilation (first presentation / short stricture; low durability)" — First-presentation short stricture ≤2 cm OR poor surgical candidate; bridging measure
  • Urethral dilation (sequential filiform-follower or balloon)
    first line

Auto-drafted A&P note

outpatient

Subjective

- Possible entry pathways: Progressive weak stream / hesitancy / straining / spraying / incomplete emptying — possible USD (AUA male urethral stricture 2017 PMID 27993339); Inability to void with palpable bladder — AUR; route to uro.acute-urinary-retention.v1 for STAT decompression; Recurrent UTI in adult man with weak stream → stricture workup; route to uro.uti.complicated.v1 overlap.

Objective

- No vitals, labs, or imaging entered for this encounter.

Assessment

**Urethral Stricture Disease (bulbar / penile / pan-urethral / LSA / iatrogenic / post-traumatic / pediatric / bladder-neck-contracture)** (uro.urethral-stricture.v1).
Phenotype framing: USD vs BPH (older man, gradual onset, no trauma history) vs prostate cancer vs neurogenic bladder (DM / MS / CVA / cord) vs urethritis (acute STI) vs urethral cancer (rare, hematuria + mass on RUG) vs meatal stenosis (LSA distal) vs bladder-neck contracture (post-TURP / RP) (AUA 2017)
Scope: Male patient (adult / geriatric / pediatric) with chronic obstructive voiding suggesting urethral stricture vs BPH vs prostate cancer vs urethritis. Female stricture rare → urogyn. Pediatric post-hypospadias repair stricture → peds uro subspecialty (AUA male urethral stricture 2017)

No severity triggers fired against current inputs.

Plan

Regimen axis: **AUA 2017 — dilation → DVIU (first / short bulbar) → urethroplasty (definitive — anastomotic / substitution / flap) + LSA topical clobetasol + bladder-neck-contracture endoscopic + pediatric peds-uro** — step "STEP 1 — Urethral dilation (first presentation / short stricture; low durability)".
1. Urethral dilation (sequential filiform-follower or balloon) (procedure_office, first line) — AUA 2017 — short-term symptom relief; low durability; bridge to definitive (PMID 27993339; PMID 23416644)

Setting playbook (outpatient) — RUG / VCUG / cystoscopy for diagnosis + segment / length / complexity; risk-stratified ladder; surgical referral if urethroplasty candidate; LSA topical management; surveillance post-intervention (AUA 2017)
2. tamsulosin (bridging α-blocker for mild symptoms) 0.4 mg PO daily PO once daily — Mild obstructive voiding while awaiting definitive surgery (AUA 2017 — limited effect on true urethral stricture; bridging symptom relief; document for IFIS if cataract pending)
3. clobetasol 0.05% topical (LSA) Apply BID to affected area × 12 wk then taper topical BID — LSA meatal / distal stricture phenotype (AUA 2017 — first-line LSA)

Non-pharmacologic actions:
- Refer to urology for definitive surgical planning (urethroplasty candidacy) if long / recurrent / complex
- Pelvic-floor PT for stress UI overlay post-RP
- Counsel recurrence rates — 5-yr ~10% urethroplasty, 30–50% DVIU
- LSA — annual derm surveillance
- Pediatric — peds uro referral for post-hypospadias-repair stricture

AVOID / contraindication checks:
- Repeat_DVIU_low_yield_after_first_failure_urethroplasty_preferred (AUA 2017)
- Clobetasol_class_I_steroid_taper_after_12wk_skin_atrophy_risk (AUA 2017)
- Do_not_force_foley_through_impassable_stricture_use_suprapubic (AUA 2017)
- Treat_UTI_before_any_instrumentation_DVIU_or_urethroplasty (AUA 2017)
- LSA_biopsy_if_atypical_rule_out_SCC (AUA 2017)
- Tamsulosin_IFIS_risk_for_pending_cataract (AUA BPH 2021)

Monitoring

Regimen monitoring:
- IPSS Qmax PVR at 3 6 12mo post intervention (AUA 2017)
- cystoscopy if symptom recurrence (AUA 2017)
- annual derm surveillance for LSA (AUA 2017)
- voiding trial post op after foley removal (AUA 2017)
- LSA taper clobetasol to maintenance after 12wk (AUA 2017)

Setting (outpatient) monitoring:
- IPSS + Qmax + PVR at 3, 6, 12 mo post-intervention (AUA 2017)
- Cystoscopy if symptoms recur (AUA 2017)
- LSA clobetasol response at 12 wk then taper (AUA 2017)

Follow-up plan: Annual uroflow + symptom score; LSA lifelong derm surveillance; counsel recurrence rate (5-yr ~10% urethroplasty, 30–50% DVIU); pediatric — follow growth + repeat eval (AUA 2017)
- Close-out criterion: follow-up + counselling complete

Monitoring phase: IPSS + Qmax + PVR at 3, 6, 12 mo post-intervention; cystoscopy if symptoms recur; LSA — annual derm / uro for ongoing inflammation; AUR post-op — Foley duration + voiding trial (AUA 2017)

Disposition

Current setting: outpatient — RUG / VCUG / cystoscopy for diagnosis + segment / length / complexity; risk-stratified ladder; surgical referral if urethroplasty candidate; LSA topical management; surveillance post-intervention (AUA 2017)

Disposition criteria:
- Stable on ladder step + surveillance (AUA 2017)
- Refer to urology if surgical candidate (AUA 2017)

Escalation triggers (move to higher acuity):
- AUR → STAT ED for suprapubic catheter (uro.acute-urinary-retention.v1)
- Urosepsis (fever + obstruction) → ED + IV abx
- Obstructive AKI → admit

Earlier-Return Triggers

Return-precaution thresholds (watch for):
- [SEVERE] Pan-urethral / long-segment stricture (>2 cm OR multi-segment) — substitution urethroplasty with buccal mucosa graft OR staged Johanson repair; high complexity (AUA 2017)
- [MODERATE] Post-traumatic stricture — bulbar (straddle injury) or membranous PFUI (pelvic fracture); RUG mandatory; delayed urethroplasty 3–6 mo after stabilisation (AUA 2017 PMID 27993339)
