Bacillus Calmette-Guérin Perfusion Treatment via Cutaneous Ureterostomy for Carcinoma in Situ of the Upper Urinary Tract

Introduction: Bacillus Calmette-Guérin instillation is an established therapy for the treatment of carcinoma in situ of the upper urinary tract. Case Presentation: A 72-year-old woman underwent radical cystectomy with cutaneous ureterostomy for invasive bladder cancer with carcinoma in situ of both ureters. For the treatment of upper urinary tract carcinoma in situ, an infusion of 40 mg bacillus Calmette-Guérin through each ureterostomy was performed once weekly for 5 times. Urine cytology of the left upper urinary tract became negative, with a recurrence-free survival of 4 months. On the other hand, the right upper urinary tract became temporarily negative but turned positive after 3 months. Conclusion: Bacillus Calmette-Guérin perfusion therapy via cutaneous ureterostomy is considered as one of the useful therapies for carcinoma in situ of the upper urinary tract. Furthermore, there are several factors to be discussed, including the treatment duration, dosage and secondary therapeutic options.
