RESUMO
Durante la última década, se ha producido un rápido desarrollo en la nefroscopia y la ureterorrenoscopia flexible, litotricia láser y diferentes instrumentos para manejar las litiasis. Realizaremos una revisión del empleo del láser en distintas situaciones. Se deben hacer esfuerzos para minimizar el daño renal y el láser juega un papel importante en el tratamiento de pacientes con urolitiasis y riñones en herradura, insuficiencia renal crónica, pacientes neurológicos (AU)
During the last decade there has been a rapid development in flexible nephroscopy, flexible ureterorenoscopy, laser lithotripsy and instruments for stone manipulation. We are going to review the use of Laser in the management of lithiasis in different situations. Efforts should be made to minimize renal injury and lasers play a significant role in patients with urolithiasis and horseshoe kidneys, chronic renal failure, neurological patients (AU)

OBJECTIVES: The present study reports a case of bilateral synchronous renal oncocytoma and reviews similar cases described in the literature. METHODS: The present case was incidentally discovered in an 81-year-old female during evaluation for GI disease. The arteriogram was suggestive of oncocytoma and was confirmed by aspiration biopsy. The patient refused surgery. At 42 months' follow-up, the size and degree of invasion of both tumors remain unchanged. To our knowledge, only 20 cases of bilateral synchronous oncocytoma have been reported in the literature and only 6 of these were multifocal lesions. RESULTS: Renal oncocytoma, like salivary gland lesions, may spread as an advanced stage multifocal nodular oncocytic hyperplasia. Therefore it is not surprising to detect multiple synchronous or metachronous oncocytomas. CONCLUSIONS: Bilateral renal masses are a diagnostic and therapeutic difficulty, and even more so in the absence of systemic manifestations, hereditary disorders or a family history of renal tumor.
