Age/Sex: _____ / M / F
Date: 14 July 2026
Reg. No.: ___________
BP: _____ Wt: _____ kg
DIAGNOSIS
- Right renal/ureteric calculus - 6 mm (USG confirmed)
- Right renal colic
- Lower urinary tract symptoms (LUTS) - possibly secondary to calculus / concurrent UTI
- R/O Urinary Tract Infection (urine C&S pending)
INVESTIGATIONS ADVISED
| Test | Reason |
|---|
| Urine Routine & Microscopy (spot) | Hematuria, pyuria, casts |
| Urine Culture & Sensitivity | Rule out UTI, guide antibiotic |
| Serum Creatinine, BUN | Baseline renal function |
| Serum Calcium, Uric Acid, Phosphorus | Stone metabolic workup |
| CBC with differential | Infection markers |
| Non-contrast CT KUB (NCCT) | Gold standard for stone sizing/location; sensitivity 99% vs 70% for IVU |
| X-ray KUB (plain) | Radiopaque stone tracking |
| 24-hr urine calcium, oxalate, uric acid (if recurrent) | Stone prevention |
Rx
1. ANALGESIA (Pain Relief - First Priority)
Tab. Diclofenac Sodium 50 mg + Serratiopeptidase 10 mg
- 1 tab orally TID (three times daily) - after food
- x 5 days
- (NSAIDs are first-line for renal colic; they reduce ureteral smooth muscle tone and decrease renal pelvic pressure)
OR if severe/vomiting:
Inj. Diclofenac 75 mg/3 mL IM (stat, if oral not tolerated)
- Deep IM once, followed by oral NSAID when tolerated
Tab. Tramadol 50 mg + Paracetamol 325 mg (rescue analgesia)
- 1 tab orally SOS (when pain persists despite NSAID)
- Not more than 3 tabs/day
- (Opioids as second-line; avoid as monotherapy)
2. ANTISPASMODIC (Smooth Muscle Relaxant)
Tab. Hyoscine Butylbromide (Buscopan) 10 mg
- 1 tab orally TID - after food
- x 5 days
- (Reduces ureteral and bladder spasm, relieves colic and urgency/frequency symptoms)
3. MEDICAL EXPULSIVE THERAPY (MET) - Stone Passage Aid
Tab. Tamsulosin 0.4 mg (alpha-1 blocker)
- 1 cap orally OD - at bedtime (to minimize orthostatic hypotension)
- x 4 weeks
- (Alpha blockers relax ureteral smooth muscle; recommended in most guidelines for distal ureteral stones <10 mm to facilitate spontaneous passage. For a 6 mm stone, spontaneous passage rate is ~50-60%; MET improves this - Comprehensive Clinical Nephrology, 7th Ed.)
- Note: Counsel about postural hypotension; avoid driving immediately after first dose
4. FOR BURNING MICTURITION & FREQUENCY
Tab. Nitrofurantoin 100 mg SR (empirical, pending C&S)
- 1 tab orally BD - with food
- x 5-7 days
- (Excellent urinary tract tissue penetration; preferred for uncomplicated lower UTI; stop or switch per C&S report)
OR if allergy / unavailable:
Tab. Norfloxacin 400 mg
- 1 tab orally BD - on empty stomach (1 hr before / 2 hrs after food)
- x 5 days
Tab. Phenazopyridine 200 mg (urinary analgesic)
- 1 tab orally TID after food
- x 2-3 days only
- (Provides symptomatic relief from burning; warn patient urine will turn orange-red - this is harmless)
5. URINE ALKALIZER
Syrup / Sachet Potassium Citrate + Citric Acid (e.g., Uritek / Lithoril)
- 10 mL in 100 mL water TID after meals
- x 4 weeks
- (Alkalizes urine; reduces uric acid stone growth; reduces stone recurrence; also soothes urinary epithelium)
6. ANTI-NAUSEA (if present)
Tab. Ondansetron 4 mg
- 1 tab orally BD - before food
- x 3 days
- (Renal colic often causes nausea/vomiting; also reduces opioid-induced nausea if tramadol used)
7. GI PROTECTION (Gastroprotection with NSAIDs)
Tab. Pantoprazole 40 mg
- 1 tab orally OD - 30 min before breakfast
- x 5 days
- (Mandatory with NSAID use to prevent gastric ulceration)
8. SUPPLEMENTATION
Tab. Pyridoxine (Vitamin B6) 40 mg
- 1 tab OD
- x 4 weeks
- (Reduces endogenous oxalate production; stone prevention)
GENERAL INSTRUCTIONS (Lifestyle / Dietary)
- Fluid intake: Drink at least 2.5 - 3 litres of water/day - distributed throughout the day including at night. Target urine output >2 L/day. This is the single most important preventive measure.
- Diet:
- Reduce oxalate-rich foods: spinach, nuts, chocolates, tea, beets
- Moderate animal protein (red meat, poultry)
- Normal calcium intake (do NOT restrict; low calcium diet paradoxically increases stone risk)
- Reduce sodium - high salt increases urinary calcium excretion
- Reduce cola/aerated drinks (high phosphoric acid)
- Activity: Mild ambulation and walking encouraged - helps stone passage
- Strain urine through a fine cloth/filter and collect any stone fragment for analysis (stone composition guides long-term prevention)
- Avoid alcohol during antibiotic and NSAID course
FOLLOW-UP & REFERRAL PLAN
| Timeline | Action |
|---|
| 48-72 hours | Review urine C&S report; adjust antibiotic if needed |
| 1 week | Reassess pain, fever, urine symptoms; repeat urine R/E |
| 4 weeks | Repeat USG KUB - check stone position/size, passage confirmation |
| If no passage in 4-6 weeks | Urology referral for ESWL (extracorporeal shock wave lithotripsy) |
| URGENT referral if | Fever >38.5°C (sepsis), anuric, solitary kidney, bilateral stones, persistent vomiting |

CLINICAL RATIONALE SUMMARY
- A 6 mm stone has approximately 50-60% spontaneous passage rate. Stones <4 mm pass in ~80% cases; >7 mm rarely pass spontaneously (Comprehensive Clinical Nephrology, 7th Ed.).
- Tamsulosin MET is supported by multiple meta-analyses for distal ureteral stones <10 mm and is recommended in AUA/EAU guidelines.
- NSAIDs (diclofenac) are first-line analgesia for renal colic - they are superior to opioids and reduce ureteral spasm.
- Burning micturition + frequency in the context of a stone may represent: (a) stone at ureterovesical junction causing bladder irritation, (b) secondary/concomitant UTI - treat empirically, refine per C&S.
- NCCT KUB is the gold standard imaging (99% sensitivity) and should be performed to precisely locate the stone and guide intervention planning.
- Urgent urology referral if: fever (obstructive uropathy + sepsis), worsening renal function, no passage at 4-6 weeks, or intractable pain.
