RESUMO
OBJECTIVE: To describe the clinical case of a patient presenting a squamous cell carcinoma in a duplicated renal pelvis, after percutaneous nephrolithotomy. METHODS/RESULTS: 60-year-old male patient who was diagnosed of a squamous cell carcinoma of the renal pelvis in the pathological study of a lower pole nephrectomy after percutaneous nephrolithotomy for staghorn calculi in the left lower pole renal moiety. The patient suffered a bladder recurrence one year and a half later. A radical cystoprostatectomy was performed, but the patient died in a few months due to metastasis. CONCLUSIONS: Squamous cell carcinoma of the renal pelvis is a rare tumor with poor prognosis, associated with stone disease and chronic infection. Taking biopsies from suspicious lesions during percutaneous nephrolithotomy may help early diagnosis and improve survival.

Objetivo: Describir un caso clínico de un paciente que presenta un carcinoma de células escamosas en una pelvis renal bífida, tras la realización de una nefrolitotomía percutánea. Métodos/Resultados: Paciente varón de 68 años de edad, diagnósticado de carcinoma escamoso de pelvis renal, tras el estudio histológico de una nefrectomía polar inferior posterior a una nefrolitotomía percutánea por una litiasis coraliforme en hemirriñón izquierdo. El paciente sufrió una recidiva vesical un año y medio más tarde, se practicó una cistoprostratectomía radical, pero el fallecimiento se dio a los pocos meses ante la presencia de metástasis. Conclusiones: El carcinoma de células escamosas de pelvis renal, es un tumor raro y de mal pronóstico, generalmente asociado con enfermedad litiásica e infección crónica. La realización de biopsias de zonas sospechosas durante la nefrolitotomía percutánea puede ayudar al diagnóstico precoz del tumor, con la consiguiente mejoría de la supervivencia (AU)
