Steroids — Perioperative Management
For the reconstructive urologist, steroid decision-making falls into three overlapping scenarios: chronic glucocorticoid use (renal transplant, IBD, rheumatologic disease, interstitial cystitis, chronic asthma/COPD) requiring stress-dose coverage; dexamethasone as a perioperative adjunct for PONV, anti-inflammation, and ERAS compliance; and the wound-healing and infection consequences of chronic steroids after reconstruction (urethroplasty take, prosthetic infection risk, anastomotic leak). This article covers all three, built on the 2024 European Society of Endocrinology / Endocrine Society Joint Clinical Guideline on glucocorticoid-induced adrenal insufficiency.[4]

Who Is at Risk for Perioperative Adrenal Insufficiency
Chronic exogenous glucocorticoids suppress the HPA axis. The risk of adrenal crisis under surgical stress depends on dose, duration, and route:[4]
Likely Suppressed (Assume Need for Stress Dosing)
- Prednisone ≥5 mg/day (or equivalent) for ≥3 weeks in the last year
- Cushingoid features on exam
- Prior known adrenal insufficiency (primary, secondary, or tertiary)
- Recent taper from chronic high-dose steroids
Indeterminate (Consider Biochemical Assessment if Feasible)
- Prednisone 5–10 mg/day for several weeks
- Prolonged high-dose inhaled corticosteroid (e.g., fluticasone >880 μg/day)
- Prolonged high-potency topical steroid over large surface area
- Repeated intra-articular injections
Unlikely Suppressed (No Stress Dose Needed)
- Prednisone <5 mg/day regardless of duration
- Any steroid use for <3 weeks
- Standard-dose inhaled or topical steroids
- Single recent short course (unless repeated)
Biochemical assessment (when uncertain and time permits): morning cortisol before 9 AM. A level >15–18 μg/dL rules out adrenal insufficiency; <3 μg/dL confirms it; intermediate values warrant a low-dose (1 μg) or standard (250 μg) cosyntropin stimulation test. In practice, if stress dosing is being considered in a patient likely to need surgery within a useful window, empirically cover rather than defer — the risk of adrenal crisis exceeds the low risk of a few days of supplementation.
Core Principle
All patients on chronic glucocorticoids should continue their usual daily dose perioperatively, regardless of dose or chronicity.[1][2] Additional stress-dose steroids are then layered on top, calibrated to surgical complexity and baseline dose.
The working rule: don't let them miss their usual dose + cover the extra stress.
Stress-Dose Regimens by Surgical Complexity
Based on the 2024 ESE / Endocrine Society Joint Clinical Guideline.[4]
Minor Stress — Minor Surgery / Local Anesthesia
Examples for urology: cystoscopy, stent exchange, intravesical therapy, scrotal surgery under local, office-based procedures.
- Patients already on hydrocortisone ≥40 mg/day, prednisone ≥10 mg/day, or dexamethasone ≥1 mg/day: no dose increase needed unless hemodynamic instability develops.
- Lower doses or non-daily users: increase to hydrocortisone 40 mg total the day of procedure (20 mg 1 h before + 10 mg at 6 h + 10 mg at 12 h).
- Continue increased dose if the patient remains unwell.
Moderate to Major Stress — General or Regional Anesthesia, Short Recovery
Examples for urology: TURP, TURBT, pyeloplasty, moderate urethroplasty, ureteral reimplant, robotic pyeloplasty or partial nephrectomy, RARP.
Intraoperative:[4]
- Hydrocortisone 100 mg IV bolus at induction
- Then continuous hydrocortisone 200 mg/24 h infusion
- If infusion not feasible: hydrocortisone 50 mg IV q6 h
Postoperative:[4]
- Resume oral glucocorticoid at increased dose for 48 h:
- Hydrocortisone 40 mg/day in 3 divided doses, or
- Prednisone 10 mg/day, or
- Dexamethasone 1 mg once daily
- Then resume pre-surgical dose.
- If complications develop (pain, infection, fever): maintain the increased oral dose or continue IV stress-dose coverage.
Major Stress — Surgery With Prolonged NPO or Long Recovery
Examples for urology: radical cystectomy with urinary diversion, major pelvic reconstruction with bowel, open nephrectomy with IVC thrombus, complex posterior urethroplasty, emergency urologic surgery in a septic patient.
Intraoperative: same as moderate (100 mg IV bolus + 200 mg/24 h infusion).
Postoperative:[4]
- Continue hydrocortisone 200 mg/24 h IV while NPO.
- Once eating and uncomplicated: resume oral glucocorticoids at 2–3× basal dose, then taper to pre-surgical dose over 2–3 days.
- Continue elevated dose if complications (sepsis, re-operation, prolonged ICU stay).
Important Exception — the Already-Stress-Dosed Patient
Patients already on hydrocortisone ≥200 mg/day, prednisone ≥50 mg/day, or dexamethasone ≥6–8 mg/day at baseline do not need further dose increases unless hemodynamic instability develops.[4] They are already on pharmacologically supraphysiologic doses.
Special Situations
Labor and Vaginal Delivery
- Hydrocortisone 100 mg IV bolus at onset of labor.
- Then 50 mg IV q6 h or continuous 200 mg/24 h infusion.[3][4]
Cesarean Section
- Treat as major-stress NPO regimen (see above).
Septic Patient / Intraoperative Hemodynamic Decompensation
- Hydrocortisone 100 mg IV immediately for any unexplained, fluid-unresponsive hypotension in a known or suspected steroid-dependent patient before, during, or after surgery.[2][3][5]
- Do not wait for biochemical confirmation — the risk of treating an uninterrupted stress response is minimal, and the risk of untreated adrenal crisis is death.
Inhaled / Topical / Intra-Articular Steroids
- Standard inhaled or topical doses rarely cause clinically meaningful HPA suppression.
- High-dose fluticasone (>880 μg/day) or repeated intra-articular steroid injections have case reports of adrenal suppression — consider biochemical assessment before major surgery.
Adrenal Crisis — Recognition and Treatment
An underappreciated perioperative emergency. Mortality is high when missed, near-zero when treated promptly.[5]
Recognition
- Unexplained hypotension unresponsive to fluid resuscitation
- Shock without another clear etiology
- Abdominal pain, nausea, vomiting
- Hyponatremia, hyperkalemia
- Hypoglycemia
- Fever
- Altered mental status
In a postoperative patient on chronic steroids with any of these findings — especially shock without response to volume — adrenal crisis is on the differential.
Treatment
Do not wait for labs.
- Hydrocortisone 100 mg IV immediate bolus.
- Aggressive IV fluid resuscitation — normal saline, 1 L in the first hour, then as needed.
- Dextrose if hypoglycemic.
- Continue hydrocortisone 200 mg/24 h IV infusion (or 50 mg q6 h).
- Identify and treat the precipitating stressor — infection, MI, bleeding, missed dose.
- Draw cortisol and ACTH before the first dose if feasible, but never delay treatment for labs.
- Transition to oral hydrocortisone as patient stabilizes and can tolerate PO.
Once the crisis resolves, the patient should be educated on steroid emergency injection training (100 mg hydrocortisone IM auto-injector) and wear an emergency ID bracelet.
Dexamethasone as Perioperative Adjunct
Single-dose IV dexamethasone (typically 4–8 mg at induction) is one of the most commonly used anesthetic adjuncts for several reasons:[4]
- PONV prophylaxis — reduces 24 h PONV; first-line component of dual/triple antiemetic bundles for Apfel score ≥2 (see Nausea & Vomiting)
- Anti-inflammatory — part of multimodal analgesia
- Adjunctive analgesia — prolongs nerve block duration when given with local anesthetic
Safety signals:
- Transient hyperglycemia — particularly relevant in diabetics; coordinate with glucose management (see Diabetes)
- No increase in SSI from a single intraoperative 4–8 mg dose in meta-analysis
- No effect on wound healing at single-dose perioperative amounts
- Beware additive PONV reduction from multiple corticosteroids — a stress-dosed patient does not additionally need 8 mg dexamethasone at induction; the stress dose covers the antiemetic effect
Steroid Effects on Wound Healing and Reconstruction
This is the urology-specific concern.
Mechanism
Chronic glucocorticoids impair:
- Fibroblast proliferation and collagen synthesis
- Neutrophil and macrophage function
- Epithelialization
- Angiogenesis
- Neutrophil chemotaxis (increasing SSI risk)
Clinical Consequences in Reconstructive Urology
- Buccal mucosal graft take — impaired in patients on chronic >10 mg/day prednisone equivalent
- Urethroplasty anastomotic healing — slower; higher re-stricture rate
- Prosthetic implant infection risk — AUS, IPP, sling — chronic steroids elevate infection rates independent of diabetes
- Wound dehiscence after cystectomy / open nephrectomy
- Bowel anastomotic leak — chronic >20 mg/day prednisone is an independent risk factor (see Bowel Anastomosis)
- Osteoporosis — relevant for pelvic reconstructive surgery, vertebral compression fracture risk during positioning
Preoperative Mitigation Where Possible
- Taper to lowest effective dose in coordination with the prescribing specialist before elective reconstruction.
- Optimize vitamin D and calcium status.
- Document informed consent regarding elevated wound-healing and infection risk.
- For elective prosthetic urology — consider deferral until steroid can be tapered below 10 mg/day prednisone equivalent.
Evidence and Controversy
The evidence base for routine stress-dose steroids is limited and dated.[1][2] Recent physiologic studies suggest chronic high-dose steroid users may retain ability to increase endogenous cortisol in response to surgical stress. However:
- The consequences of untreated adrenal crisis are catastrophic.
- The cost and harm of stress-dose coverage is low.
- Current guidelines favor cautious stress-dose coverage for moderate to major surgery.
Population data show a sharp mortality increase in the first 3–6 months after discontinuation of long-term oral glucocorticoids, with hypotension, GI symptoms, hypoglycemia, and hyponatremia — a reminder that the biggest risk window is after an abrupt stop, not during routine therapy.[4]
GU-Specific Quick Reference
| Scenario | Approach |
|---|---|
| Renal transplant patient (typically on prednisone 5 mg/day) undergoing elective reconstructive urology | Continue daily dose + moderate-stress regimen (100 mg HC at induction + 200 mg/24 h if open / major, 50 mg q6 h if MIS); taper off stress dose by POD 2 |
| Chronic IBD patient on prednisone 15 mg/day for cystectomy | Continue daily dose + major-stress NPO regimen; transition to oral 2–3× basal when eating |
| Rheumatoid arthritis patient on prednisone 7.5 mg/day for pyeloplasty | Continue + moderate-stress regimen |
| IC patient on chronic low-dose prednisone for sling revision | Continue + minor-stress (no dose increase if ≥10 mg/day equivalent) |
| Asymptomatic patient on fluticasone inhaled 220 μg/day for asthma undergoing RARP | No stress dose needed |
| Unexplained postoperative shock on prednisone history | Hydrocortisone 100 mg IV immediately without waiting for biochemical confirmation |
Key Recommendations
- Always continue the baseline daily dose perioperatively.
- Layer stress dose on top, calibrated to surgical complexity.
- Minor surgery / local anesthesia: usually no dose increase in patients on ≥10 mg prednisone equivalent.
- Moderate-major surgery: hydrocortisone 100 mg IV at induction + 200 mg/24 h infusion (or 50 mg q6 h).
- NPO / long recovery: continue IV 200 mg/24 h until eating, then 2–3× basal oral, then taper.
- Already on supraphysiologic doses (≥50 mg prednisone equivalent): no additional stress dose needed.
- Adrenal crisis — 100 mg hydrocortisone IV immediately for unexplained shock; do not delay for labs.
- Dexamethasone 4–8 mg at induction is a standard PONV / anti-inflammatory adjunct; watch glucose in diabetics.
- Optimize chronic steroid dose downward before elective reconstruction when feasible to protect wound healing and implants.
