Surgery is typically performed with the assistance of a general anesthetic. A local or regional anesthetic is also administered during the procedure in order to minimize postoperative discomfort. Sutures used for the repair eventually dissolve. With most techniques, a soft drainage catheter is left within the neourethra for approximately 7-10 days following surgery. This allows urine to drip into the diaper and initial healing to take place without the need for the baby to void urine over the fresh repair site.
The use of optical magnification, meticulous surgical technique, and proper handling of delicate tissues are important aspects of successful surgery. Complete repair is typically performed with one surgical procedure. However, some of the more severe hypospadias defects require a "two-stage" repair. The first stage involves straightening of the penis, if necessary, and repositioning of penile skin in preparation for formation of the neourethra at the second stage. The second stage is performed approximately six months after the first.
Depending on the extent of surgery, the baby may either go home on the day of surgery (following successful recovery from anesthesia) or stay in the hospital one night for observation. Following the surgery the caretaker is asked to apply an antibiotic ointment to the penis several times each day. A small daily dose of antibiotic may be prescribed to decrease the risk of infection and acetaminophen should be given for pain management. The patient and repair are typically reevaluated one and then several months following surgery.
