MARTIN MARTIN, Sergio et al. Squamous cell carcinoma in a duplicated renal pelvis after percutaneous nephrolithotomy. Arch. Esp. Urol. [online]. 2008, vol.61, n.5, pp.633-636. ISSN 0004-0614.

Objective: To describe the clinical case of a patient presenting a squamous cell carcinoma in a duplica-ted 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 recu-rrence 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 suspicio-us lesions during percutaneous nephrolithotomy may help early diagnosis and improve survival.
