Struvite staghorn calculi in crossed fused ectopia

Area of Science:

• Nephrology
• Urology
• Surgical Pathology

Background:

• Crossed fused renal ectopia presents unique challenges for managing complex kidney stones.
• Struvite staghorn calculi are associated with urinary tract infections (UTIs) and anatomical anomalies.

Observation:

• Two patients with struvite staghorn calculus in crossed fused renal ectopia were identified.
• Anomalous extrarenal arterial vasculature was noted in both ectopic and non-ectopic kidneys.

Findings:

• Both patients underwent successful anatrophic nephrolithotomy for calculus removal.
• Patients remained free of recurrent calculous disease post-surgery.

Implications:

• Anatrophic nephrolithotomy is an effective treatment for struvite staghorn calculi in complex renal ectopia.
• Understanding vascular anomalies is crucial for surgical planning in these patients.
