Partial cystectomy is a surgical procedure that involves the removal of a portion of the bladder. This operation is typically performed to treat conditions such as bladder cancer or severe bladder dysfunction. By removing only the affected part, the goal is to preserve as much of the bladder's function as possible. After a partial cystectomy, patients may experience changes in urinary function, but many can still maintain a relatively normal lifestyle. The surgery may be followed by additional treatments, such as radiation therapy or chemotherapy, depending on the underlying condition and the extent of the disease.
