A Nesbit is a surgical procedure used to straighten a curved penis. First performed in 1965, it works by shortening the longer side of the penis so it matches the shorter side, correcting the bend. It’s one of the most established and widely used operations for penile curvature, whether the curve is something you were born with (congenital) or developed later due to a condition called Peyronie’s disease, where scar tissue forms inside the penis and pulls it to one side.
How the Procedure Works
The penis has a tough, fibrous outer layer called the tunica albuginea that surrounds the two chambers responsible for erections. When one side of this layer is shorter than the other, whether from scar tissue or natural anatomy, the penis curves during erection. A Nesbit procedure corrects this by removing a small, ellipse-shaped piece of tissue from the convex (longer) side, then stitching the edges together. This effectively shortens the longer side to match the shorter one, pulling the penis straight.
The surgery is performed under general or regional anesthesia. The skin of the penis is pulled back, and the surgeon creates an artificial erection to precisely measure the curvature. Then, working on the opposite side from the curve, small sections of the tunica are excised and closed with permanent sutures. If the curvature is significant, multiple small excisions may be made rather than one large one to keep the repair smooth and even. The neurovascular bundle, which carries sensation, is carefully moved aside during the operation.
Modified Techniques and Plication
Since the original procedure was described, several variations have emerged. The most notable is the Yachia technique, which makes a lengthwise incision in the tunica instead of removing an ellipse of tissue, then closes it horizontally. This achieves the same shortening effect with a slightly different approach.
Plication techniques take the concept further by skipping the tissue removal entirely. Instead of cutting out a piece of the tunica, the surgeon places permanent sutures that bunch the longer side together, pinching it shorter. One approach uses inverted knots that sit inside small grooves cut into the surface, keeping them from being felt under the skin. Another uses a small incision near the base of the penis and places a series of short plication sutures along the area of greatest convexity. These variations are sometimes grouped under the broader term “modified Nesbit” procedures, though technically they work on a different principle: folding tissue rather than removing it.
Who Is a Good Candidate
The procedure is best suited for people who have adequate erectile function, either naturally or with the help of oral medications or other therapies. This is an important distinction: a Nesbit corrects curvature, but it does not treat erectile dysfunction. If erections are too weak for intercourse regardless of the curve, a different surgical approach, such as a penile implant, is typically more appropriate.
For Peyronie’s disease specifically, the American Urological Association recommends waiting until the condition has stabilized before considering surgery. That usually means at least 12 months after symptoms first appeared and 3 to 6 months of stable, unchanged curvature. Operating during the active inflammatory phase risks recurrence because the scar tissue may still be evolving. Congenital curvature doesn’t have this waiting period since the anatomy isn’t changing.
Grafting procedures, where the scar tissue is cut and a patch of tissue is placed over the gap, are an alternative for more severe or complex deformities. But for straightforward curvature in someone with good erections, the Nesbit and its variations remain a first-line option because of their reliability and lower complication profile.
Success Rates
The Nesbit procedure has strong long-term results. In a study tracking outcomes of a modified Nesbit technique for congenital curvature, complete straightening was achieved in 92.8% of patients. Patient satisfaction matched closely at 90.9%. These numbers are consistent with what most surgical centers report, making it one of the more predictable urological operations.
Penile Shortening and Other Risks
The most commonly discussed tradeoff is penile shortening. Because the procedure works by making the longer side shorter rather than lengthening the curved side, some loss of length is inherent to the technique. In one analysis of outcomes, 19 patients experienced shortening of more than 2 centimeters, though only 4 of those reported that it actually affected sexual function. For most people, the shortening is modest enough that the improved straightness more than compensates.
Erectile function can be affected, but this is less straightforward than it sounds. In the same study, 10 patients had impaired erections after surgery, but most of them already had some degree of erectile difficulty before the operation. The procedure itself carries a relatively low risk of new erectile problems in someone who had normal function beforehand.
Other potential risks include temporary numbness at the tip of the penis from nerve handling during surgery, swelling, and the rare possibility of suture-related discomfort if a knot becomes palpable under the skin. Recurrence of curvature is possible but uncommon with proper candidate selection and stable disease.
Recovery Timeline
Recovery is faster than many people expect. Most people return to work and normal daily activities within two to three days. The main restriction is sexual activity: intercourse, masturbation, and oral sex are off-limits for six weeks to allow the sutures and tissue to heal fully. Cycling and similar activities that put pressure on the area should be avoided for about four weeks. Mild swelling and bruising are normal in the first week or two and resolve on their own.
