title: Transitional cell carcinoma: A rare development in congenital ureteropelvic junction obstruction kidney.
abstract: A 54-year-old male chronic smoker presented with hematuria 13 years after being diagnosed with an asymptomatic left non-functioning kidney secondary to congenital ureteropelvic junction obstruction. On evaluation, he was diagnosed with renal collecting system mass occupying the lower pole region, for which radical nephroureterectomy with bladder cuff excision and nodal dissection was carried out.
