If bone metastasis occurs in prostate cancer, it is advanced prostate cancer and is not suitable for radical surgical resection. However, if urinary tract obstruction is combined with urinary tract obstruction, or even urinary retention in severe cases, and the catheter cannot be removed after catheterization, transurethral resection of the prostate can be performed to relieve the obstruction and restore normal urinary function. If the bone metastasis occurs in the spine, drugs such as zoledronic acid should be applied at the same time to slow down the bone destruction.
