What This Guide Covers
Surgery by Stone Size & Location - Quick Answer:
| Situation | Surgery Needed? | Procedure |
|---|---|---|
| Ureteral stone ≤10mm | NO initially | MET (Tamsulosin) x 4-6 weeks |
| Ureteral stone >10mm or failed MET | YES | URS (ureteroscopy) |
| Renal stone <2cm, non-lower-pole | Possibly | SWL (first-line) |
| Renal stone <2cm, lower-pole | YES | RIRS (flexible URS) |
| Renal stone >2cm | YES | PCNL |
| Staghorn calculus | YES (urgent) | PCNL - must achieve complete clearance |
| Bladder stone | YES | Cystolitholapaxy + treat cause (BPH etc.) |
| Infected obstruction | YES (emergency) | Drain first (stent/nephrostomy), surgery later |
Why each procedure:
- SWL - non-invasive, outpatient, but lower single-session success; fragments must pass
- URS/RIRS - direct vision, active extraction, ideal for distal ureter and <2cm renal stones; avoids percutaneous access
- PCNL - highest stone-free rates for large/complex stones; powerful lithotripsy through skin tract
- Open surgery - <1% of cases; reserved for failed endourology or simultaneous anatomical reconstruction

A detailed medical clinical decision flowchart poster for urinary stone (urolithiasis) management. Professional hospital-grade poster with dark navy blue and teal color scheme on white background. Title: "CLINICAL DECISION FLOWCHART: URINARY STONE MANAGEMENT". The flowchart flows top to bottom with diamond decision boxes and rectangular action boxes. Flow: Start box "Stone confirmed on Non-contrast CT KUB" → Diamond "Sepsis + Obstruction?" → YES branch leads to red emergency box "EMERGENCY: IV Antibiotics + Ureteric Stent / Nephrostomy → Definitive Rx after 2-6 weeks". NO branch continues to Diamond "Stone Location?" with three branches: RENAL, URETERIC, BLADDER. RENAL branch → Diamond "Size?" → less than 5mm: "Hydration + Analgesia, Watchful waiting" → 5-10mm: "MET: Tamsulosin 0.4mg OD x 4-6 wks" → greater than 10mm goes to Diamond "Renal stone size?" → less than 2cm non-lower-pole: "SWL (ESWL)" → less than 2cm lower-pole: "RIRS (Flexible URS)" → greater than 2cm: "PCNL" → Staghorn: "PCNL Multi-tract". URETERIC branch → Diamond "Size + Location?" → Distal less than 10mm: "MET + Observation" → Distal greater than 10mm: "Semi-rigid URS" → Proximal less than 10mm: "SWL or Flexible URS" → Proximal greater than 10mm: "Flexible URS". BLADDER branch: "Cystolitholapaxy + Treat cause (BPH/stricture)". Bottom section has a legend box with color codes: Green=Conservative, Blue=Endoscopic, Orange=Percutaneous, Red=Emergency. Footer: "Sources: EAU/AUA Guidelines 2025 | Bailey & Love 28th Ed | Schwartz Surgery 11th Ed". Clean, legible font, all text clearly readable, professional medical poster layout.
A professional medical comparison table poster titled "ESWL vs URS vs PCNL: Surgical Modality Comparison for Urinary Stones" with dark teal header on white background. Three-column comparison table with rows comparing the three procedures. Column headers with procedure icons: ESWL (Extracorporeal Shockwave Lithotripsy) in blue, URS/RIRS (Ureteroscopy) in green, PCNL (Percutaneous Nephrolithotomy) in orange. Rows with clear data: 1) Stone Size: ESWL=less than 2cm non-lower-pole / URS=less than 2cm, all ureteric / PCNL=greater than 2cm, staghorn. 2) Stone Free Rate: ESWL=70-80% (single session) / URS=90-95% / PCNL=95-98%. 3) Overall Complication Rate: ESWL=12.5% / URS=15% / PCNL=20.2%. 4) Major Complications: ESWL=Steinstrasse, hematoma / URS=Stricture, perforation less than 1% / PCNL=Bleeding needs embolisation 1-3%, Sepsis, Pleural injury. 5) Invasiveness: ESWL=Non-invasive / URS=Minimally invasive / PCNL=Percutaneous access. 6) Anaesthesia: ESWL=Sedation/LA / URS=GA/Spinal / PCNL=GA. 7) Hospital Stay: ESWL=Day case / URS=Day case to 1 night / PCNL=2-3 days. 8) Retreatment Rate: ESWL=High (20-40%) / URS=Low (5-10%) / PCNL=Very low (2-5%). 9) Stent Required: ESWL=No / URS=Usually (JJ stent) / PCNL=Nephrostomy tube. 10) Best For: ESWL=Non-lower-pole renal less than 2cm, proximal ureter / URS=Distal/mid ureter, renal less than 2cm / PCNL=Large/complex renal, staghorn. 11) Contraindications: ESWL=Pregnancy, coagulopathy, pacemaker / URS=Ureteral stenosis / PCNL=Pregnancy, active UTI, anticoagulation. Bottom: Source citation: Cochrane 2023 PMID 37526261; Network meta-analysis complication data. Color-coded rows alternating light grey and white.

<h3 style="color:#b7791f; margin-bottom:12px; font-size:1rem;">⭐ CLINICAL PEARLS — Prescribing for Stone Disease</h3>
<div class="pearl"><strong>Pearl 1:</strong> NSAIDs (Diclofenac) are more effective than opioids for renal colic — they work on the prostaglandin-mediated ureteric spasm at the root cause. Give IV/IM diclofenac FIRST unless contraindicated.</div>
<div class="pearl"><strong>Pearl 2:</strong> Tamsulosin is the king of MET. Always prescribe with food (evening meal), warn about retrograde ejaculation (14%) and postural hypotension. Maximum 6 weeks — don't continue indefinitely.</div>
<div class="pearl"><strong>Pearl 3:</strong> For uric acid stones — potassium citrate can DISSOLVE the stone. Target urine pH 6.5-7.0 twice daily. Check dipstick in clinic. No surgery needed if compliance is good.</div>
<div class="pearl"><strong>Pearl 4:</strong> Allopurinol: Check HLA-B*5801 BEFORE prescribing in South Asians (high risk of Stevens-Johnson Syndrome). Adjust dose for renal impairment (eGFR <60: reduce by 50%).</div>
<div class="pearl"><strong>Pearl 5:</strong> Nitrofurantoin FAILS in renal impairment (eGFR <45) — doesn't reach therapeutic urine concentrations. Switch to cefalexin or trimethoprim in this setting.</div>
<div class="pearl"><strong>Pearl 6:</strong> NEVER restrict dietary calcium in calcium oxalate stone formers. This paradoxically INCREASES oxalate absorption from the gut. Prescribe calcium WITH meals to bind intestinal oxalate.</div>
<div class="pearl"><strong>Pearl 7:</strong> Drotaverine (Drotin) is extremely popular in Indian practice for colic. While evidence vs NSAIDs is limited, it has an excellent safety profile and can be used safely in pregnancy.</div>
<div class="alert"><strong>EMERGENCY:</strong> In infected obstruction (urosepsis) — START antibiotics within 1 hour + emergency drainage. Do NOT delay for investigations. Time = kidney function.</div>

- Indirect (lateral): Through deep inguinal ring → inguinal canal → superficial ring → scrotum; congenital or acquired; most common in young men
- Direct (medial): Through Hesselbach's triangle (inferior epigastric vessels laterally, inguinal ligament inferiorly, rectus laterally); acquired weakness; older men
- Reducible: Contents return to abdomen spontaneously or with pressure
- Irreducible (incarcerated): Cannot be reduced; bowel trapped; tender; obstructive symptoms
- Strangulated: Blood supply cut off → ischemia → gangrene → perforation; SURGICAL EMERGENCY
- Sudden severe pain in hernia + systemic symptoms
- Tense, tender, irreducible swelling
- Overlying skin red/dusky
- Absent cough impulse
- Signs of intestinal obstruction
- Reducible hernia: Elective herniorrhaphy (Lichtenstein tension-free mesh repair)

CASE 3: ACUTE INTESTINAL OBSTRUCTION
Master Guide
- Mechanical (most common):
- Adults: Adhesions (post-surgery #1) > hernia > malignancy > volvulus
- Children: Intussusception > congenital bands > Hirschsprung's
- Paralytic ileus: Post-op, peritonitis, electrolyte imbalance, drugs
- Colicky abdominal pain
- Distension
- Vomiting (bilious early = high obstruction; feculent late = low)
- Absolute constipation (no flatus + no stool = complete obstruction)
- High SI obstruction: Early vomiting, less distension
- Low SI obstruction: Less vomiting, marked distension, late feculent vomiting
- Large bowel obstruction: Gross distension, late or no vomiting, closed-loop if ileocaecal valve competent
- Distension (graded 1-4)
- High-pitched tinkling bowel sounds (mechanical) vs absent (ileus)
- Ladder pattern tenderness (SI loops)
- Check ALL hernial orifices (missed hernia = missed obstruction!)
- Rectal exam (rectal carcinoma, impaction, bloody stool = intussusception)
- AXR: Dilated loops, air-fluid levels, absence of gas in rectum
- Erect AXR: Multiple air-fluid levels (step-ladder pattern)
- CT abdomen (gold standard): Identifies transition point, cause, strangulation
- 70-80% of adhesive SBO resolves conservatively within 24-48 hours
- Water-soluble contrast (Gastrografin) enema: diagnostic + therapeutic in adhesive SBO
- Signs of strangulation (peritonism, fever >38.5, WBC >15,000, tachycardia)
- Complete LBO (risk of caecal perforation if >12cm diameter)
- Closed-loop obstruction
- No resolution after 48hrs conservative management
CASESHEET 3: ACUTE INTESTINAL OBSTRUCTION
Patient: Mrs. Priya, 45F, Post-cholecystectomy 3 years ago
CC: Colicky abdominal pain, distension, vomiting x 2 days; no flatus x 1 day
EXAMINATION
Vitals: BP 108/72, HR 106, Temp 37.6°C
Abdomen: Grossly distended; visible peristalsis
Tinkling high-pitched bowel sounds
Generalised tenderness (no peritonism)
Hernial orifices: Intact
Rectal: Empty rectum
AXR: Multiple dilated small bowel loops with air-fluid levels; no gas in colon/rectum
CT Abdomen: Transition point at mid-jejunum; dilated loops proximal; no evidence of
strangulation; likely adhesive band SBO
DIAGNOSIS: Adhesive Small Bowel Obstruction (non-strangulated)
CONSERVATIVE MANAGEMENT ("DRIP AND SUCK")
1. NBM IMMEDIATELY
2. NGT INSERTION: Free drainage (decompress dilated bowel); chart hourly output
3. IV Access + Urinary catheter
4. IV Fluids: Hartmann's 1L/8hrly + replacement of NGT losses mL-for-mL
5. Monitoring: Vital signs q2hrly; strict fluid balance
6. ANALGESIA: Inj. Morphine 2.5-5mg IV PRN; Inj. Buscopan 20mg IV for colicky pain
7. ANTI-EMETIC: Inj. Metoclopramide 10mg IV 8hrly
8. ELECTROLYTES: Correct K+ (common hypokalaemia in obstruction)
If K+ <3.2: Add KCl 20mmol/L to IVF; recheck in 4 hours
9. Do NOT give laxatives or enemas without surgical review
10. Serial abdominal examinations q4hrly
11. Repeat AXR at 12 and 24 hours to assess progress
REVIEW TRIGGERS FOR EMERGENCY SURGERY:
- Any peritonism developing
- Temp >38.5°C
- WBC >15,000
- HR >110 or BP falling
- No improvement/worsening at 48hrs
IF CONSERVATIVE FAILS (48hrs):
- Gastrografin (water-soluble contrast) 100mL via NGT → AXR at 8h (therapeutic + diagnostic)
- If no improvement → Theatre: Adhesiolysis ± bowel resection
DISCHARGE: When fully resolved, tolerating diet, bowel sounds normal, passing flatus
Advice: High-fibre diet; return if recurrence
CASE 4: SUPERFICIAL ABSCESS / PERIANAL ABSCESS
Master Guide
- Cellulitis (no pus yet): Antibiotics alone
- Abscess formation (fluctuant): Incision and Drainage (I&D) - antibiotics are adjunctive only
- Spreading cellulitis: Antibiotics + urgent surgical review
- Redness, warmth, swelling, tenderness (rubor, calor, tumor, dolor)
- Fluctuance (fluctuation test positive)
- Pointing (skin thinning over abscess)
- Systemic: Fever, rigors, raised WBC
- Most arise from infected anal glands (cryptoglandular theory)
- Types: Perianal (50%), Ischiorectal (25%), Intersphincteric, Supralevator
- URGENT drainage required - can spread rapidly to perineum (Fournier's gangrene!)
- Never give antibiotics alone for perianal abscess without drainage
- LA infiltration (lignocaine 1% with adrenaline) OR GA for large/deep abscess
- Cruciate/elliptical incision over point of maximum fluctuance
- Break loculi with finger/forceps
- Irrigate with normal saline
- Pack loosely with ribbon gauze (or leave open for secondary intention)
- Send pus for culture and sensitivity

2. IV access; FBC, BSL, HbA1c, coagulation
3. Control blood sugar: Actrapid insulin sliding scale pre/peri-procedure
4. IV ANTIBIOTICS (diabetic patient — risk of spreading infection):
- Inj. Co-amoxiclav 1.2g IV 8hrly (Augmentin)
OR Inj. Piperacillin-Tazobactam 4.5g IV 8hrly (if immunocompromised/severe)
Start 1 hour before procedure; continue 48hrs
5. PROCEDURE (I&D):
- Position: Left lateral or lithotomy
- LA: Lignocaine 1% + Adrenaline 1:200,000 — ring block around abscess
- Cruciate incision over point of maximum fluctuance
- Drain pus; break loculi with finger; irrigate with saline
- Pus for C&S (critical in diabetic)

If inhalation injury: Early intubation BEFORE airway swells shut
- O2: 100% via non-rebreather mask x 4 hours
- Remove all clothing and jewellery
2. IV ACCESS: Two large-bore (14-16G) IVs (avoid burned areas; use femoral if needed)
3. URINARY CATHETER: Strict hourly urine output (target 0.5-1 mL/kg/hr = 28-55 mL/hr)
4. FLUID RESUSCITATION (Parkland Formula):
Ringer's Lactate (Hartmann's) 5940 mL total
- Next 6 hours: 495 mL/hr (remaining first half)
- Hours 8-24: 185 mL/hr
ADD Maintenance: 5% Dextrose 35 mL/hr separately
5. ANALGESIA (burns are extremely painful):
- Inj. Morphine 5mg IV titrated PRN q2-4hrly
- Cover burns temporarily with cling film (NOT cold water on large burns — hypothermia)
- Inj. Morphine 2mg/hr IV infusion if pain inadequate
6. WOUND CARE (after resuscitation stable):

3. ANALGESIA: Tab. Paracetamol 1g QDS + Ibuprofen 400mg TDS (anti-inflammatory)
4. DRAINAGE (Unilocular — USS guided aspiration preferred):
PROCEDURE: Ultrasound-guided needle aspiration
- USS guidance to locate collection
- 18G wide-bore needle; aspirate all pus
- Send pus for C&S
- Repeat aspiration q48hrs until dry (usually 2-3 sessions)
- If fails/multiloculated → formal I&D under GA with radial incision
BREASTFEEDING:
- CONTINUE breastfeeding from BOTH breasts (including affected side)
- Breastfeeding from infected side is SAFE (antibiotics pass into milk but safe for baby)
- Expressing milk helps clear infection and maintains supply
- Only pause if drainage wound directly over nipple/areola
STEP-DOWN TO ORAL (after 48hrs IV):
- Cap. Flucloxacillin 500mg PO QDS x 14 days total course
- (Empty stomach — absorbs better when fasting)
