| Date of Operation | 17/07/2026 |
| Parameter | Value |
|---|---|
| Temperature | 98.1°F (Afebrile) |
| Pulse | 66 beats/min, regular |
| Respiratory Rate | 20 breaths/min |
| Blood Pressure | Not recorded |
Note on discordance: The patient attributed the pain to flatulence/gas, but the clinical assessment identified it as right flank pain consistent with ureteric colic. This is a common presentation - ureteric pain is often visceral and colicky, and patients may misinterpret it as GI discomfort.
| Left kidney stone | Small (~2 mm), previously treated medically (likely with alpha-blockers / hydration for spontaneous expulsion) |
| ESWL (Extracorporeal Shock Wave Lithotripsy) | 3 sessions - received in 2025, for the right-sided stone |
| Investigation | Expected Finding / Relevance |
|---|---|
| NCCT KUB (Non-contrast CT - gold standard) | Identify stone size, location, density (Hounsfield units), and degree of hydronephrosis |
| USG abdomen & pelvis | Assess hydronephrosis, kidney size |
| Urine routine & microscopy | Microhematuria, pyuria, crystals |
| Urine culture & sensitivity | Rule out UTI prior to surgery |
| Serum creatinine / BUN | Baseline renal function |
| Serum electrolytes, calcium, uric acid | Stone risk factors |
| CBC | Baseline; WBC for infection |
| Coagulation profile (PT/INR) | Pre-operative requirement |
| X-ray KUB | Radio-opaque stones (calcium oxalate/phosphate visible; uric acid stones are radio-lucent) |
| IVP (Intravenous Pyelogram) | If needed for anatomy (less common with CT available) |
| Diagnosis | Supporting / Against |
|---|---|
| Ureteric calculus (right) - PRIMARY | Colicky flank pain, previous stone history, prior ESWL, NCCT likely confirmatory |
| Right renal colic | Part of same spectrum |
| Appendicitis | Right-sided, but no fever, no vomiting, no RIF guarding documented |
| Musculoskeletal pain | No postural/movement correlation clearly documented |
| Right renal pelvis / UPJ obstruction | Possible if stone at PUJ |

Academic note on HU value: Hounsfield Unit (HU) of a stone on NCCT predicts stone composition and helps guide treatment. HU >1000 indicates a hard stone (typically calcium oxalate monohydrate) - these are resistant to ESWL, which explains why 3 sessions of ESWL in 2025 failed to clear it. Laser ureteroscopy (Ho:YAG) is the preferred modality for such hard, ESWL-resistant stones.
Academic note: The right ureter crosses the L3 vertebral level in the upper ureter. A radio-opaque shadow at L3 right side on plain X-ray, in a patient with right flank pain, is highly suggestive of an upper ureteric calculus. Calcium-containing stones are radio-opaque; uric acid stones are radio-lucent and invisible on plain X-ray.
Note on size discrepancy: CT shows 8.2 mm; USG shows 12 mm. This is a known phenomenon - USG overestimates stone size due to acoustic shadowing and measurement artifact. NCCT KUB is more accurate for stone sizing and is the gold standard. The CT measurement of 8.2 mm should be taken as the true size.

Etiology / risk factor Present in book Present in patient
| Risk Factor | Description |
|---|---|
| Age | Most common between 20-55 years; peak incidence in 3rd-5th decade |
| Sex | Males are 2-3x more likely to develop stones than females |
| Family / Personal History | H/O previous stones significantly increases recurrence risk |
| Geography | Higher incidence in hot, dry climates ("stone belt") - increased sweating = concentrated urine |
| Genetic factors | Cystinuria (autosomal recessive), idiopathic hypercalciuria have genetic components |
| Risk Factor | Description |
|---|---|
| Low fluid intake / Dehydration | Most important factor - concentrated urine promotes crystal supersaturation and precipitation |
| Dietary factors | High animal protein, high sodium, high oxalate diet (spinach, nuts, tea), low calcium diet paradoxically increases oxalate absorption |
| Occupation | Sedentary jobs, outdoor workers in hot environments with inadequate hydration |
| Obesity / Metabolic syndrome | Associated with uric acid and calcium oxalate stones |
| Hypercalciuria | Excess calcium in urine - due to hyperparathyroidism, absorptive or renal causes |
| Hyperoxaluria | Excess oxalate - dietary or malabsorption-related |
| Hyperuricosuria | Excess uric acid - associated with gout, high purine diet |
| Hypocitraturia | Citrate is a natural inhibitor of stone formation; its absence promotes stones |
| Urinary tract infection | Urea-splitting bacteria (Proteus, Klebsiella) cause struvite stones |
| Urinary stasis / Obstruction | Promotes crystal deposition |
| Medications | Indinavir, carbonic anhydrase inhibitors, triamterene, laxative abuse |
| Immobilization | Increases bone calcium resorption and urinary calcium |
| Risk Factor from Book | Present in Patient? | Details |
|---|---|---|
| Age 20-55 years (peak) | ✅ YES | 34 years - within peak incidence group |
| Male sex | ✅ YES | Male - 2-3x higher risk than females |
| Personal history of stones | ✅ YES | H/O left kidney stone (treated medically); now right ureteric stone - bilateral stone disease = high recurrence tendency |
| H/O previous ESWL | ✅ YES | 3 settings of ESWL in 2025 - stone was partially resistant |
| Occupation - physically demanding / outdoor | ✅ LIKELY | Electrician - outdoor work, physical exertion, likely inadequate hydration during work in West Bengal heat |
| Hot climate / geography | ✅ YES | West Bengal, India - hot and humid climate, heavy sweating leads to concentrated urine |
| Low fluid intake (presumed) | ✅ LIKELY | Occupation as electrician with outdoor work and no documentation of adequate fluid intake |
| Dietary factors | NOT DOCUMENTED | No detailed dietary history available in records |
| Hypercalciuria | BORDERLINE | Serum Ca²+ = 10.1 mg/dL (upper limit of normal) - 24-hr urine calcium pending |
| Hyperuricosuria | ❌ NO | Serum uric acid = 4.89 mg/dL - within normal range |
| Hypertension / Metabolic syndrome | ❌ NO | No H/O HTN, DM documented |
| Obesity | NOT DOCUMENTED | BMI not calculated (weight 65 kg, height not recorded) |
| Medications causing stones | ❌ NO | No such medications |
| UTI / Infection | ❌ NO | No fever, no dysuria, no documented UTI |
| Immobilization | ❌ NO | Active, ambulatory patient |
| Family history | NOT DOCUMENTED | Not elicited in history |
The most likely contributing risk factors in this patient are: male sex, age in peak stone-forming decade, hot climate (West Bengal), occupation as electrician (outdoor work with possible inadequate hydration), bilateral stone disease history (left kidney + right ureter), and borderline serum calcium. The stone composition is most likely calcium oxalate based on HU ~1200 on NCCT.
Please give it in one table with descriptions
| Sr. No. | Risk Factor | Present in Book (Description) | Present in Patient |
|---|---|---|---|
| 1. | Age (20-55 years) | Peak incidence of urinary calculi occurs between 20-55 years of age. Stone formation is most common in the 3rd to 5th decade of life | ✅ Present - Patient is 34 years old, falls within the peak incidence age group |
| 2. | Male Sex | Males are 2-3 times more likely to develop urinary calculi than females due to higher urinary excretion of calcium and uric acid | ✅ Present - Patient is male |
| 3. | Personal History of Stones | Previous history of urinary calculi is the strongest predictor of recurrence. Recurrence rates are 11% at 2 years, 20% at 5 years, and 31% at 10 years | ✅ Present - H/O left kidney stone (treated medically) + 3 sessions of ESWL in 2025 for right-sided stone. Bilateral stone disease indicates high recurrence tendency |
| 4. | Hot Climate / Geography | People living in hot, dry, or tropical climates are at higher risk due to increased sweating, reduced urine volume, and concentrated urine promoting crystal supersaturation | ✅ Present - Patient lives in West Bengal, India - hot and humid climate with heavy sweating |
| 5. | Occupation | Outdoor workers, physically demanding occupations, and those with limited access to fluids during work are at higher risk due to chronic mild dehydration and concentrated urine | ✅ Present - Patient is an Electrician - outdoor physical work, likely with inadequate fluid intake during work hours |
| 6. | Low Fluid Intake / Dehydration | Most important modifiable risk factor. Reduced fluid intake leads to concentrated urine, increased solute supersaturation, and crystal precipitation. Daily urine output should be >2 L to reduce stone risk | ✅ Likely Present - Occupation as outdoor electrician in hot climate suggests inadequate hydration; no documentation of adequate fluid intake in records |
| 7. | Dietary Factors | High animal protein increases urinary calcium, oxalate, and uric acid excretion. High sodium increases urinary calcium. High oxalate foods (spinach, nuts, tea) promote calcium oxalate stones. Low calcium diet paradoxically increases oxalate absorption from gut | Not documented - detailed dietary history not elicited in available records |
| 8. | Hypercalciuria | Excess urinary calcium is the most common metabolic abnormality in stone formers. Causes include hyperparathyroidism, absorptive hypercalciuria, and renal hypercalciuria. Calcium-containing stones account for ~80% of all stones | ⚠️ Borderline - Serum Ca²+ = 10.1 mg/dL (upper limit of normal). 24-hour urine calcium not yet done. PTH not checked. Warrants post-op metabolic workup |
| 9. | Hyperuricosuria | Excess urinary uric acid promotes uric acid stone formation and also acts as a nidus for calcium oxalate stones. Associated with gout, high purine diet, and chemotherapy | ❌ Absent - Serum uric acid = 4.89 mg/dL (normal range). Uric acid stone unlikely |
| 10. | Hypocitraturia | Citrate is a natural inhibitor of stone crystallization. Low urinary citrate levels remove this protective mechanism and promote stone formation | Not assessed - 24-hour urine citrate not done |
| 11. | Urinary Tract Infection | Urea-splitting bacteria (Proteus, Klebsiella, Staphylococcus) convert urea to ammonia, raising urinary pH and promoting struvite (magnesium-ammonium-phosphate) stone formation | ❌ Absent - No fever, no dysuria, no documented UTI. Stone composition likely calcium oxalate (HU ~1200), not struvite |
| 12. | Metabolic Disorders (DM, Obesity) | Obesity and diabetes are strongly associated with kidney stones, particularly uric acid and calcium oxalate types. Insulin resistance reduces urinary citrate and increases uric acid excretion | ❌ Absent - No H/O DM. No documented obesity (weight 65 kg) |
| 13. | Immobilization | Prolonged immobilization increases bone resorption, raises serum and urinary calcium, promoting calcium stone formation | ❌ Absent - Patient is ambulatory and active |
| 14. | Family History | First-degree relatives of stone formers have 2-3x higher risk due to shared genetic and dietary factors. Conditions like cystinuria and idiopathic hypercalciuria have genetic components | Not documented - family history of stone disease not elicited |
| 15. | Medications | Indinavir, carbonic anhydrase inhibitors, triamterene, and laxative abuse increase risk of stone formation | ❌ Absent - No such medications in patient's records |

| 6. | Metabolic / Genetic Disorders | Conditions like hyperparathyroidism, renal tubular acidosis, cystinuria (autosomal recessive), and idiopathic hypercalciuria have a genetic or inherent metabolic basis that predisposes to stone formation | ⚠️ Borderline - Serum Ca²+ = 10.1 mg/dL (upper limit of normal). PTH not checked. Metabolic workup pending post-operatively |
| MODIFIABLE RISK FACTORS | |||
| 7. | Low Fluid Intake / Dehydration | Most important modifiable risk factor. Reduced fluid intake leads to concentrated urine, increased solute supersaturation, and crystal precipitation. Daily urine output should be >2 L to reduce stone risk | ✅ Likely Present - Outdoor electrician in hot climate; no documentation of adequate fluid intake. Chronic mild dehydration highly probable |
| 8. | Occupation | Outdoor workers and those in physically demanding jobs with limited access to fluids during work hours are at higher risk due to chronic dehydration and excessive sweating | ✅ Present - Patient is an Electrician - outdoor physical work, likely with inadequate fluid intake during work hours |
| 9. | Dietary Factors | High animal protein increases urinary calcium, oxalate, and uric acid. High sodium increases urinary calcium. High oxalate foods (spinach, nuts, tea) promote calcium oxalate stones. Low calcium diet paradoxically increases oxalate gut absorption | Not documented - detailed dietary history not elicited in available records |
| 10. | Hypercalciuria | Excess urinary calcium is the most common metabolic abnormality in stone formers (~80% of stones are calcium-containing). Causes include hyperparathyroidism, absorptive and renal hypercalciuria | ⚠️ Borderline - Serum Ca²+ = 10.1 mg/dL (upper limit of normal). 24-hour urine calcium not yet done.

| 12. | Hypocitraturia | Citrate is a natural inhibitor of stone crystallization. Low urinary citrate removes this protective mechanism and promotes stone formation. Low fruit/vegetable intake is a common cause | Not assessed - 24-hour urine citrate not done. To be checked in metabolic workup |
| 13. | Urinary Tract Infection | Urea-splitting bacteria (Proteus, Klebsiella, Staphylococcus) convert urea to ammonia, raise urinary pH, and promote struvite stone formation - most common cause of staghorn calculi | ❌ Absent - No fever, no dysuria, no documented UTI. Stone is likely calcium oxalate (HU ~1200), not struvite |
| 14. | Obesity / Metabolic Syndrome (DM) | Obesity and diabetes are strongly associated with kidney stones, particularly uric acid and calcium oxalate types. Insulin resistance reduces urinary citrate and increases uric acid excretion | ❌ Absent - No H/O DM or documented obesity. Weight 65 kg |
| 15. | Immobilization | Prolonged immobilization increases bone resorption, raises serum and urinary calcium, promoting calcium stone formation | ❌ Absent - Patient is active and ambulatory |
| 16. | Medications | Indinavir, carbonic anhydrase inhibitors, triamterene, and laxative abuse increase risk of stone formation by altering urinary chemistry | ❌ Absent - No such medications documented in patient records |
Past medical and surgical history
| Sr. No. | Condition | Details | Status |
|---|---|---|---|
| 1. | Urinary Calculus - Left Kidney | Patient gives history of left kidney stone, approximately 2 mm in size. Treated conservatively with medication (likely alpha-blockers / hydration for spontaneous expulsion - exact medication unknown as per patient) | Resolved - treated medically |
| 2. | Hypertension | No history of hypertension | ❌ Absent |
| 3. | Diabetes Mellitus | No history of diabetes mellitus | ❌ Absent |
| 4. | Thyroid Disease | No history of thyroid disorder | ❌ Absent |
| 5. | Tuberculosis | No history of tuberculosis | ❌ Absent |
| 6. | Allergy | Allergic to Brinjal (Eggplant) - food allergy. No known drug allergy documented | ⚠️ Food allergy - Brinjal |
| Sr. No. | Surgery / Procedure | Details | Year |
|---|---|---|---|
| 1. | Right Forearm Fracture Fixation Surgery | Patient gives history of surgical fixation of right forearm fracture. Nature of fixation (ORIF / K-wire / plating) not documented | Approximately 20 years ago (~2006) |
| 2. | ESWL - Extracorporeal Shock Wave Lithotripsy | 3 sessions of ESWL performed for right-sided ureteric/renal stone. Stone was resistant to ESWL (likely due to high stone density - HU ~1200 on NCCT), leading to current surgical intervention | 2025 (3 settings) |
Clinical Significance of Past History:
- Bilateral stone disease (left kidney + right ureter) strongly suggests an underlying systemic metabolic predisposition - warrants complete metabolic workup post-operatively
- 3 failed ESWL sessions directly explain why laser ureteroscopy was chosen as definitive treatment
- No co-morbidities (no HTN, DM, thyroid disease) - patient is otherwise healthy, which contributed to low anaesthetic risk for GA
Past medical and surgical history
| Sr. No. | History | Present in Book (What to Assess & Why) | Present in Patient |
|---|---|---|---|
| PAST MEDICAL HISTORY | |||
| 1. | Previous Urinary Calculi | Lewis emphasizes that personal history of urinary stones is the single strongest risk factor for recurrence. A prior stone episode increases recurrence risk significantly - 50% recurrence within 10 years without preventive measures | ✅ Present - H/O left kidney stone (~2 mm), treated conservatively with medication. Now presenting with right ureteric calculus - bilateral stone disease confirming recurrent stone former |
| 2. | Hypertension | HTN is associated with increased risk of urinary stone disease and also affects renal perfusion. Must be assessed pre-operatively for anaesthetic risk | ❌ Absent - No history of hypertension. BP on admission 130/80 mmHg - normal |
| 3. | Diabetes Mellitus | DM is associated with uric acid stone formation due to insulin resistance reducing urinary pH and citrate. Also increases surgical and anaesthetic risk | ❌ Absent - No history of DM. FBS/PPBS = 66 / HbA1c = 5.4 - normal |
| 4. | Thyroid Disease | Hyperthyroidism increases bone resorption and urinary calcium, predisposing to calcium stone formation | ❌ Absent - No history of thyroid disease |
| 5. | Tuberculosis | Renal TB can cause calcification, strictures, and predispose to stone formation due to urinary stasis and altered anatomy | ❌ Absent - No history of TB |
| 6. | Gout / Hyperuricemia | Gout is associated with uric acid stone formation due to elevated serum and urinary uric acid levels | ❌ Absent - No history of gout. Serum uric acid = 4.89 mg/dL (normal) |
| 7. | Recurrent UTI | Recurrent UTIs with urea-splitting organisms (Proteus, Klebsiella) lead to struvite stone formation. History of UTI is important to elicit | ❌ Absent - No history of recurrent UTI. No fever or dysuria at presentation |
| 8. | Allergy History | Lewis states allergy history must always be documented before any surgical or medical intervention to prevent adverse drug reactions | ⚠️ Present - Allergic to Brinjal (eggplant) - food allergy. No known drug allergy documented. Relevant to nursing care - dietary modifications needed |
| PAST SURGICAL HISTORY | |||
| 9. | Previous Urological Surgery / Procedures | Lewis highlights that previous urological instrumentation, anatomical abnormalities, or prior stone procedures directly influence current surgical planning and risk of complications | ✅ Present - H/O ESWL x 3 sessions in 2025 for right-sided stone. Stone proved resistant to ESWL (high HU ~1200), necessitating current laser ureteroscopy |
| 10. | Previous Any Surgery under Anaesthesia | Prior surgical and anaesthetic history must be assessed for complications such as adverse reactions to anaesthesia, bleeding disorders, or post-operative complications that may affect current surgical management | ✅ Present - H/O right forearm fracture fixation surgery approximately 20 years ago (~2006). No documented complications from that surgery or anaesthesia |
| 11. | Bleeding Disorders / Anticoagulant Use | Lewis emphasizes assessing for any bleeding tendency or anticoagulant use pre-operatively to reduce risk of intra-operative and post-operative haemorrhage | ❌ Absent - PT/INR = 1.02 (normal). No anticoagulant use documented |
