Incisions and grafting technique

The incision and grafting technique is a surgical procedure that aims to correct the Peyronie’s disease without causing a loss of penis length.

Penis straightening while maintaining the length

An alternative to the commonly used Nesbit procedure for treating Peyronie’s disease is the incisions and grafting technique. This technique aims to correct the existing curvature of the penis while maintaining or restoring length. The Nesbit procedure, on the other hand, achieves penis straightening by losing length. The incisions and grafting technique works with lengthening the shorter (concave) side of the penis.

Facts about Peyronie’s disease & incisions and grafting technique

Maintaining the length is possible

Maintaining penis length

Maintaining penis length should receive a high priority during the treatment, as Peyronie’s disease itself already causes significant loss of length. Studies confirm that 80% of affected men suffer from loss of penis length due to Peyronie’s disease. Further loss due to surgical intervention can put a significant strain on the patient, as the functionality of the penis and psychosexual well-being of the patient are strongly affected.

– Peyronie’s disease –
Plaque causes the development of the curvature

A convex and a concave side of penile curvature

Visualising the curvature through diagrams can help understanding the issue better.

There are two sides to a penile curvature: a longer one (convex) and a shorter one (concave).

– The two sides of penile curvature –
The short “concave side” and the long “convex side

The plaque, which causes the curvature, is located on the shorter/concave side. It reduces elasticity of the erectile tissue which can then no longer extend accordingly. This leads to the development of the penile curvature, indentations and subsequently loss of penis length.

The longer/convex side of the curvature is not affected by Peyronie’s disease. This side usually retains the original penis length as prior to the onset of the disease.

Incision and grafting technique – maintaining length

Thanks to the incision and grafting technique, the shorter side is adjusted to match the longer side. The incision on the shorter side of the curvature is closed using a graft.

The aim is to achieve full straightening while preventing any loss of length, as seen during the Nesbit procedure.

Advantages of incision and grafting technique

This technique aims to correct the existing curvature of the penis while maintaining or restoring original length. Only a specialist with necessary expertise and experience should perform this complex procedure.
During his specialization, Dr. Kuehhas also focused on incisions and grafting techniques, which are based on the geometric principles of the Egydio technique. He considers it one of the main techniques to treat Peyronie’s disease. This modern technique makes it possible to identify the position of the cuts intraoperatively and calculate the necessary length of the graft.



Dr Franklin Kuehhas is a medical specialist in the field of urology and andrology. He received his specialization training at the University College London. He also underwent his training at the prestigious University Hospital in Heidelberg (Germany) and at the University Hospital of Vienna (Austria). Dr Kuehhas focuses on the treatment of congenital and acquired penile curvatures (Peyronie’s disease). His research activities have resulted in many publications and improvements of surgical techniques such as the STAGE technique for congenital penile curvature treatment.
