Redo Hypospadias Surgery (Repeat Repair in Children)

Every operation reduces two things: the amount of usable healthy tissue and the blood supply to that area. Because of this, a third procedure can't be planned with the same technique as the first. The surgeon's first task is to work out what's left to use — penile skin, foreskin, or oral mucosa.

• Rushing: procedures performed before scar tissue has softened tend to break down again. At least 6 months is usually allowed to pass.
• Addressing problems piece by piece: stricture, fistula, and curvature often feed into one another, and repairs done without mapping all of them together rarely hold up long term.

• Gathering all previous operative reports — which technique and which tissue were used.
• Mapping the entire channel with contrast imaging and, if needed, endoscopy.
• Taking stock of the remaining tissue.
• Assessing the skin for lichen sclerosus.
• Measuring voiding function and the state of the bladder.

The standard approach is a staged repair: in the first stage, all scar tissue is cleared, the curvature is corrected, and the base is prepared with a graft; in the second stage, the channel is built. Oral mucosa is the most reliable tissue in this group.

• The process is spread across two, sometimes three operations, and can take more than a year in total. This isn't the process dragging on — it's what's needed for a lasting result.
