title: Nephrolithiasis and hematuria--sometimes a stony road to diagnosis.
abstract: We report a case of a young man with a history of kidney stones. Occurrence of gross hematuria several months after the extracorporeal shock wave, lithotripsy (ESWL) treatment lead to hospitalization. By ultrasound and abdominal CT scan, the urologist could exclude post-renal causes of the gross hematuria and acute renal failure. After transfer to a department of nephrology hemodialysis was started, an immediate kidney biopsy was performed and prednisolone was administered on the same day. The kidney biopsy revealed an anti-glomerular basement membrane (GBM) disease. The renal function did not recover and the patient remained on hemodialysis. In the literature it has been hypothesized that ESWL-treated patients are prone to develop anti-GBM disease by liberation of glomerular basement antigen through the ESWL high energy shock waves. An additional hypothesis considering the higher susceptibility for anti-GBM disease among certain HLA-tissue types is discussed with regard to our case. Unfortunately, the prolonged track to diagnosis and delayed immunosuppressive treatment could not prevent poor clinical outcome. Although anti-GBM disease is a rather rare disease, it should be included as a differential diagnosis for hematuria--especially months after ESWL treatment. Otherwise early diagnosis may be missed and as in our patient immunosuppressive treatment will remain unsuccessful to recover renal function.
