Yes, phalloplasty can be partly undone, but the process is delicate and the results are not a full return to the body you had before.

1. What “undoing” actually means

Surgeons can remove the outside tube of skin that was built to look like a penis and can take down the lengthened urethra so that urine exits in its original place again. “She said she can re-open the area and reverse the urethral lengthening, and come together with a plastic surgeon to remove the phallus on my belly area.” – ThatGirlChyna source [citation:b2ccac51-33e9-4266-8fec-53444f62a3ae]
The clitoris and native urethra are usually still present under the graft, so the urinary route can be re-plumbed, but any gonads or vaginal tissue that were taken away cannot be put back.

2. Where experienced teams work

The same hospital that performed the original surgery is often willing to coordinate a reversal. “I was having my transgender surgeries at Massachusetts General Hospital... she can re-open the area...” – ThatGirlChyna source [citation:b2ccac51-33e9-4266-8fec-53444f62a3ae]
If you need a specialist outside that system, Dr. Miroslav Djordjevic at Mount Sinai, New York, is the name most often mentioned for complex genital reconstruction. “The only surgeon I’ve heard about who does specialize in reconstructive genital surgery is Dr. Miroslav Djordjevic at Mount Sinai in New York.” – handygal-DIY source [citation:0f97fb5c-97df-4551-8426-06aaa77e11cc]

3. The main surgical worry

The biggest unknown is whether the urethra will work normally after it is shortened again. “The only concern she has is if everything is going to work properly, but she can do it.” – ThatGirlChyna source [citation:b2ccac51-33e9-4266-8fec-53444f62a3ae]
Scarring, fistulas or strictures can still appear, and any prior removal of ovaries means you would remain on hormone therapy for life.

4. What cannot be restored

Breast tissue, ovaries, or a uterus that were taken away cannot be replaced, and the skin of the abdomen or thigh that was used for the phallus will leave scars. “But like I said, the ovaries are gone and cannot be replaced... You need hormone replacement for life.” – TheDorkyDane source [citation:72371f6e-47ad-41e9-9356-b6be1ca19ebb]

Take-away
A reversal can give you back a more familiar urinary pattern and remove the constructed phallus, but it is a second major surgery with its own risks and it cannot restore reproductive organs or hormone production. If you are considering this step, ask the original surgical team for a joint urology/plastics plan or contact Dr. Djordjevic for a specialized opinion, and line up psychological support while you weigh the decision.
