A 59-year-old man was admitted to hospital for investigation of a 1-year history of intermittent hematuria. He had undergone ileal ureteral replacement for left renal stones 36 years earlier.Investigations
Renal ultrasonography, physical examination, abdominal plain radiography, intravenous urography, CT urography, measurement of serum levels of creatinine, urea and electrolytes, renal scintigraphy, urinalysis and urine culture.Diagnosis
Staghorn calculi in the left kidney, with a high-lying anastomosis between the renal pelvis and the proximal ileal segment.Management
The patient underwent percutaneous nephrolithotomy via a middle-calyx access for the large staghorn stones. After surgery, no residual calculi were found and the patient was discharged with an uneventful postoperative course. At 1 month, renal scintigraphy showed normal bilateral kidney function. The patient received potassium citrate supplementation and was followed up with 6-monthly imaging studies. At the last report, he had been stone-free for 7 months.
