While not common, possible complications from a hysterectomy include but are not limited to:
An injury to the bowel or bladder
An injury to nerves that regulate the bladder, causing either incontinence or overfilling of the bladder
A blood clot in the veins of the legs (called deep venous thrombosis). If such a clot floats out of the leg and lodges in the lungs, it is a more dangerous complication called a pulmonary embolism.
