[Perirenal hematoma after ESWL in a patient with stage T1 renal tumor]. / Hematoma perirrenal post ESWL en paciente con tumor renal estadio T1.

We report a case of perirenal hematoma post ESWL in a patient with controlled hypertension and a previously undiagnosed stage T1 kidney neoplasm. The foregoing complication can be partly ascribed to the renal tumor. It must therefore be taken into account that a small kidney mass may be overlooked during urography and consequently an ultrasound study of the kidney should be done before the patient is submitted to X-ray-guided lithotripsy.
