KUB (Kidney-Ureter-Bladder) X-Ray - Findings

Two Views Shown:

• Left panel - AP view of lower abdomen and pelvis
• Right panel - AP view of full KUB (kidneys, ureters, bladder)

Key Findings:

1. Large Left Renal Staghorn Calculus (Most Significant Finding)

• Seen in the right panel (upper view) in the left kidney region
• Large, dense, branching, radiopaque calcification filling the renal pelvis and calyces
• Classic "staghorn" morphology - so named because it resembles a stag's antlers
• Likely a struvite (infection stone) or calcium oxalate in etiology
• Associated with recurrent UTIs, particularly Proteus mirabilis (urease-producing organisms)

2. Metallic Foreign Body / Surgical Clip in Pelvis

• Seen in the left panel (lower view), midline pelvic region
• Small ring/C-shaped metallic density
• Likely a retained surgical clip from a prior procedure (e.g., vas deferens ligation, vascular surgery)

3. Bowel Gas Pattern

• Normal distribution of colonic gas
• No signs of bowel obstruction or ileus
• No free air under the diaphragm (no pneumoperitoneum)

4. Bony Structures

• Lumbar spine shows mild degenerative changes (spondylosis/osteophytes) - age appropriate for 58 years
• Pelvis, sacrum, and hip joints are intact
• No fractures or aggressive bone lesions

Clinical Impression:

• Percutaneous Nephrolithotomy (PCNL) - treatment of choice for staghorn calculi
• Urine culture and antibiotic therapy
• Metabolic workup to prevent recurrence

Intestinal / Bowel Gas Pattern - Detailed Analysis

Right Panel (KUB View) - Primary Focus

🔴 Notable Finding: Prominent Large Bowel Gas

• There is significant gas distension throughout the large bowel (colon), particularly visible in:
  • Ascending colon (right side)
  • Transverse colon (upper abdomen)
  • Descending colon (left side)
  • Sigmoid colon (pelvis)
• The colonic loops show haustra (incomplete bands/sacculations) - confirming large bowel
• The gas pattern is peripheral in distribution, consistent with colon

Small Bowel Assessment

• Small bowel gas is not prominently dilated
• No centrally-placed, ladder-like loops with valvulae conniventes (no classic small bowel obstruction pattern)

Key Negative Findings (Important)

Interpretation

1. Constipation / fecal loading - most likely (common in 58M)
2. Paralytic ileus - if clinically unwell
3. Colonic dysmotility - e.g., related to electrolyte imbalance, medications

• Patient is in renal colic / pain causing reflex ileus
• Post-procedure ileus if any recent intervention

⚠️ Clinical correlation is essential. Erect or lateral decubitus views would be needed to properly evaluate for air-fluid levels and confirm/exclude obstruction.
