[Systemic lupus erythematosus and pyeloureteral obstruction. Description of a case].
OBJECTIVE
To discuss the clinical implications of systemic lupus erythematosus (SLE) as a complication of a urological condition.


METHODS
Herein we describe a patient who presented with acute pyelonephritis due to ureteropelvic juntion stenosis, and a superimposed activation of SLE that had not been previously detected.


RESULTS
This form of presentation led to a delay in making the diagnosis since it was focused urologically. The diagnosis of SLE was based on the clinical features, determination of antinuclear antibodies (ANA) and a decrease in serum complement.


CONCLUSIONS
When a patient consults with fever arising from a urological condition that is refractory to conventional therapy, it is mandatory to make the differential diagnosis from other disease entities, as shown in this case.
