title: [Squamous cell carcinoma in a duplicated renal pelvis after percutaneous nephrolithotomy].
abstract: OBJECTIVE
  To describe the clinical case of a patient presenting a squamous cell carcinoma in a duplicated renal pelvis, after percutaneous nephrolithotomy.
  
  
  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.
