Aims and objectives: The gold standard therapy for locally invasive bladder cancer has long been radical cystectomy with pelvic lymph node dissection. However, approximately 50% of all patients with invasive bladder cancer die, and the outcome of this disease is closely related to its pathologic stage [1]. Furthermore, [...]

Methods and materials: Patients We performed D-BOAI in patients with bladder cancer who presented for radical cystectomy from Febrary 2016 to July 2016 but who wished to preserve bladder function. Eligible patients had histologically confirmed carcinoma in situ or stage T1, T2, T3, or T4 muscle-invasive bladder cancer wit[...]

Results: The mean value of X was 6.8 mm (range, 2.0–20.4 mm).

Conclusion: In patients with bladder cancer, several feeding arteries are present as branches of the IIA, and these arteries are very thin and difficult to detect. Thus, it is difficult to perform selective arterial infusion into these feeding arteries using micro catheter. Then, for hyperdense infusion to many[...]
