Kidney-conservative surgery followed by bacillus Calmette-Guerin instillation therapy for transitional cell carcinoma of solitary renal pelvis: a case report

We report a case (62-year-old male) of transitional cell carcinoma (grade 2) of solitary right renal pelvis which was successfully treated with tumor excision followed by bacillus Calmette-Guerin instillation therapy. He had a past history of left radical nephroureterectomy for renal pelvic tumor 11 years earlier. Kidney-preserved surgery with BCG instillation therapy is expected to be an alternative for radical forms of therapy, especially in the patients with a solitary kidney.
