A case of deep vein thrombosis after transurethral resection of bladder tumor

A solitary superficial bladder tumor was found in a 87-year-old woman. Transurethral resection of bladder tumor (TUR-Bt) was done, but right leg pain and swelling appeared two days after the operation. CT examination revealed deep vein thrombosis (DVT) at right common iliac vein level. The combined therapy of heparin, urokinase, and warfarin was started, and the DVT disappeared in the CT three months after the therapy. TUR-Bt is relatively less invasive and the frequency of DVT and pulmonary thromboembolism (PTE) is very low, however these complications may happen especially in elderly people with low ADL.
