Renal calculus complicated with squamous cell carcinoma of renal pelvis: Report of two cases.
Longstanding renal calculus is a risk factor of squamous cell carcinoma (SCC) of the renal pelvis. It is highly aggressive and usually diagnosed at advanced stages with a poor prognosis. We present two cases of kidney stone complications with renal pelvic SCC. These two patients had a radical nephrectomy and the dissected tissues were renal pelvic SCC. Our cases further emphasize that renal pel...

Nephrolithiasis, especially formation of staghorn calculi, is the most common...
متن کاملSarcomatoid Squamous Cell Carcinoma of the Renal Pelvis Masquerading as Emphysematous Pyelonephritis with Staghorn Calculus

Less commonly, long-term urothelial irritation from a calculus may also pose a risk of malignant transformation. CASE PRESENTATION A 77-year-old male with multiple medical comorbidities presented with a chronic right renal pelvic staghorn calculus and...
