Ultrasound Report Analysis - Shaswat Rajeshbhai Shah, 23M

Two Diagnoses

1. Left VUJ Calculus with Mild Hydronephrosis and Hydroureter

• Mild hydronephrosis (backpressure dilation of the kidney pelvis)
• Hydroureter down to the lower end (dilation of the ureter)

• At 4.1 mm, spontaneous passage is very likely. Stones < 4 mm pass spontaneously in ~80% of cases; distal (VUJ) stones specifically have up to 70% spontaneous passage rate, which is the highest of all ureteral locations - Comprehensive Clinical Nephrology, 7th Ed.
• The VUJ is one of the three natural narrowings of the ureter (the most common site for stones to get stuck)
• Both kidneys are otherwise normal in size/shape with preserved cortico-medullary differentiation - a good sign meaning no chronic kidney damage yet

• Conservative (watchful waiting) - given the small size (4.1 mm) and distal location, high probability of spontaneous passage
• Medical Expulsive Therapy (MET) - Tamsulosin (alpha-blocker) 0.4 mg once daily or nifedipine (calcium channel blocker) 30 mg once daily to relax the ureteral smooth muscle and facilitate stone passage; recommended in most guidelines for distal ureteral stones < 10 mm - Comprehensive Clinical Nephrology, 7th Ed.
• Analgesia - NSAIDs (e.g. diclofenac, ketorolac) are first-line for ureteric colic pain
• Hydration - encourage oral fluid intake
• Surgical intervention if: pain persists > 72 hours despite analgesia, worsening obstruction, associated UTI/sepsis, or no passage after 4-6 weeks. Options include ureteroscopy with laser lithotripsy or ESWL

• Fever/infected obstructed kidney (urosepsis) - would need emergency decompression
• Single kidney, bilateral obstruction, worsening renal function

2. Grade II Fatty Liver (Hepatic Steatosis)

• Diffusely increased liver echogenicity (brighter than kidney)
• Partial obscuration of intrahepatic vessel walls
• Liver size here is 13.1 cm (upper limit of normal)

• Lifestyle modification is the cornerstone - weight loss of 4-10% body weight is sufficient to reduce hepatic steatosis - Fuster and Hurst's The Heart, 15th Ed.
• Dietary changes: reduce simple carbohydrates, processed foods; Mediterranean diet has some evidence
• Regular aerobic exercise
• Avoid alcohol completely
• Screen for metabolic syndrome: check fasting glucose, lipid profile, HbA1c, liver function tests (ALT, AST)
• No specific FDA-approved drug exists yet for Grade II NAFLD; management is lifestyle-focused

Summary

1. Urine routine/microscopy (look for hematuria, infection)
2. Urine culture if any fever
3. Serum creatinine, urea (renal function)
4. Fasting glucose, lipid profile, liver function tests (metabolic workup for NAFLD)
5. Analgesics + tamsulosin for the stone
6. Follow-up USG in 4-6 weeks to confirm stone passage and resolution of hydronephrosis
