Interstitial cystitis has been thought to result from autoimmune phenomenon and its ocurrence in systemic lupus erythematosus(SLE)has rarely been reported. We report a case of female patient with SLE whose initial urinary symptoms were caused by intersitial cystitis. Radiography showed the reduced bladder capacity, irregularity of bladder wall, hydronephrosis and hydroureter. Deep bladder wall biopsy was performed and a diagnosis of interstitial cystitis with SLE was made. She was treated with steroid and stent insertion and showed symptomatic improvement. We consider the recognition of bladder involvement in systemic lupus erythematosus is important because it may be a reversible cause of renal failure in a patient with lupus erythematosus and adequate therapy may preserve bladder size and function.
