title: Induction of renal pelvic tumours in Sprague-Dawley rats by di-isopropanolnitrosamine.
abstract: Transitional cell papillomas and carcinomas of the renal pelvis were observed in Sprague-Dawley rats after subcutaneous (s.c.) treatment with di-isopropranolnitrosamine (DIPN). These tumours occurred unilaterally and appeared as early as 24 weeks after the commencement of treatment. The tumours frequently filled the entire renal pelvis and compressed the kidney parenchyma. The malignant neoplasms demonstrated infiltrative growth into the adjacent medullary parenchyma.
