Here are a few yoga recommendations for post-hysterectomy patients.The best thing to recommend would be Restorative yoga in the style of Judith Lasater.
I have a student who recently had a large cyst removed from her ovary in major abdominal surgery and is doing Restorative once weekly with fabulous results in comfort, energy level, peace and calming.
There is great value in these supportive postures for reducing swelling, edema, muscle strain or pain and generally supporting a return to balance after such a major assault such as abdominal surgery.
The book, Rest and Renew by Judith Lasater is a good bet for home practice or hopefully one can get out to a class regularly.
