Posterior Sagittal Anorectal Vaginal Urethral plasty (PSARVUP)

Posterior Sagittal Anorectal Vaginal Urethral plasty(PSARVUP)

Common Cloaca Surgery also called as Posterior Sagittal Anorectal Vaginal Urethral plasty (PSARVUP) is the surgical procedure done in children with Common Cloaca.  This surgery is usually done at 4 to 12 months of age. In this surgery, the new openings for potty (Anus), vagina, and urine are made at the bottom of the child to have all three openings like any normal child. 


Before this surgery, the child is examined, and Colostomy is checked, as most commonly, this colostomy must have been made at the initial days of life of the child. Some investigations of blood are done. Repeat Ultrasound is done, and an X-ray of the spine of the child (If not done before) is done. Most of the time, Distal Colostogram is done to understand the child’s anatomy and plan the procedure. Also, Cystoscopy is done to determine the length of the common Channel and make a holistic plan before common cloaca surgery. During Cystoscopy, catheters are usually left in all openings inside, and contrast studies are done through it.

Surgical Procedure for Common Cloaca:

Most of the time, this common cloaca surgery is done from the bottom of the child, and an incision is made in the midline.

Sometimes, if required, the tummy of the child might be opened. Usually, this surgery takes about 5 to 6 hours. The child’s bottom is opened, and the rectum is pulled down through the sphincters so that child may have the maximum potential for potty control afterward. Also, special emphasis is made on Urine opening and its control. A vaginal opening is also made at a normal place.


  • After PSARVUP, usually, we allow the children to feed after a few hours. If the tummy is not opened, the child is usually discharged after 2 to 3 days. But if the tummy is also opened, then hospital stay will be longer. After this common cloaca surgery, usually, pain is not very much a problem and is well-controlled.
  • We will examine the child after 2 to 3 weeks under General anesthesia, and will assess his wound.
  • We usually leave a catheter for urine in the Urinary bladder of the child, and then remove it after 3 weeks of surgery.
  • After this examination, we advise the children to start Anal Dilatation Program.
  • Once the adequate size of the Dilator is achieved, the child is ready for the next surgery (Colostomy Reversal).
