Male urogenital surgery

How to – Penile translocation


Penile translocation is performed as part of a teaser bull procedure. The goal is to minimize intromission and minimize disease transmission.

Relevant anatomy

The prepuce is moved above the flank fold so that the erection misses the vagina. The penis is not usually observed in this procedure.

The prepuce is minimally attached to the body wall. It can be readily dissected free.

Preoperative management

Food restrictions: Withhold food 48 hours. Water should be withheld if the animal is drinking excessively.

NSAIDs/analgesics: Preoperative NSAIDs are recommended.

Antibiotics: The procedure tends to be contaminated. Give preoperative antibiotics.

Local blocks: An inverted U line block around the prepuce and a ring block around the new exit site.

Position/preparation: The animal is positioned in dorsal recumbency. Inserting a long probe into the prepuce can help identify structures and minimize trauma to the sheath.

Surgery Supplies: 

  • Standard surgery instruments
  • Probe (optional)
  • Sterile rectal sleeve
  • Lap sponge forceps

Surgical procedure

  • If used, the probe is inserted into the sheath and the sheath clamped shut.
  • A circular incision is made through the skin around the prepuce.
  • The incision is continued through the skin the length of the prepuce.
  • A circle of skin is removed at the new exit site (careful with size- it will expand as soon as cut free)
  • Dissection is continued to the body wall on the cranial aspect of the prepuce. The incisions over the prepuce are extended subcutaneously around the prepuce. Try not to enter the prepuce. This should result in a prepuce that is freed from the skin and the body wall for sufficient length to move to the new site.
  • Create a subcutaneous path from the new site to the prepuce through blunt and sharp dissection.
  • Pass a sterile rectal sleeve through the new site and insert the prepuce (with preputial opening) into the sleeve. Pull/push the prepuce through to the new exit site.
  • Remove the rectal sleeve and secure the prepuce to the new site using a continuous pattern of 0 absorbable suture. Stop halfway around the opening to prevent pursestring formation.

Postoperative care

  • Suture removal in 10-14 days
  • Sexual rest 60 days


  • Dehiscence, stricture
