Surgical treatment of kidney tumor on a patient with second case of staghorn calculus and associated renal hydronephrosis: case report.

Staghorn, struvite or coral calculus are the ones that completely or partially occupies the renal pelvis and branches to the renal calices. The presence of renal calculi of any kind in the urinary tracts is related to the appearing of malign tumor in the kidneys, especially in the absence or failed treatment. A male patient, 51 years old, native of Manaus, reports about dysuria and polyuria associated with constant fever episodes and urinary tract infections with improvement by using several antibiotics but returning the symptoms after suspending it. The patient return was in a month and no improvement of the pain in the patient's feeling, with the tomography image tests result showing atrophy in the right kidney, which presents dilatation of the collector system, that it's filled with material with density varying between thick liquid and soft parts (average of 45 UH), in addition to calculus in the pelvis and ureteropelvic junction, suggesting a pattern for xanthogranulomatous pyelonephritis and matching previous history of right staghorn calculus. The association between kidney cancer and staghorn calculus should be consider through the treatment. Patients with renal diseases of severe prognosis in both kidneys must be kept under constant surveillance by the urology and nephrology team, the association of both clinics is essential to a fortunate ending like the case reported.
