In this study, we developed a new surgical strategy combining microscopic electric rotary grinding of plaques with graft repair to manage PD. The preliminary results showed that the corrective effect is satisfactory. To the best of our knowledge, this is the first study on the combined application of microscopic technology and an electric grinding drill for the surgical correction of PD. 
Currently, various treatment options are recommended for PD patients, ranging from oral medications and in...

Peyronie's disease (PD) is a chronic fibrotic condition that contributes to penile deformity, curvature, pain, sexual disability, and even leading to psychological distress1. PD likely represents a heterogeneous condition, with both heritable and environmentally-driven epigenetic factors contributing to its development and progression2. 
The reported epidemiology of PD varies and may be under-reported because of embarrassment and misconceptions about the available treatment options, with 0.4%-20.3% among different ethnicities and cohorts2,3. The treatment for PD includes conservative therapy or surgical intervention, depending on symptom severity and stability. Conservative therapy is the most common recommendation during the active phase, while more invasive treatments are reserved for the passive phase4. A recent randomized, controlled trial evaluating the efficacy of Collagenase Clostridium Histolyticum (CCH) + RestoreX penile traction vs. Surgery + RestoreX penile traction in Peyronie's disease management demonstrated comparable results between these two strategies5.
Although penile traction therapy and intralesional injections result in modest improvements for many patients, surgical intervention remains the final solution for this disease, especially for those with severe curvature and hourglass or hinge deformities1. Currently, penile straightening, such as penile plication and plaque incision or partial excision and grafting, represents the most reliable approach to correct penile curvature or deformity6. However, the reported methods have a high rate of sensory loss, erection function loss, or cosmetic dissatisfaction5,7,8. 
An electric grinder is commonly used in neurosurgery and orthopedics as an effective tool for bone shaping. It exhibits high efficiency in grinding hard tissues, like bones, while causing minimal damage to soft tissues. This characteristic gives it a unique advantage in the treatment of hard plaques.
In this study, we developed a new management strategy involving microscopic electric rotary grinding of the fibrous plaques and the use of tunica vaginalis or bovine pericardium as graft materials in the treatment of PD, which delivered high levels of patient satisfaction. This protocol is applicable for patients with severe curvature or other deformities that limit their ability to engage in satisfactory penetrative intercourse.

microscopic electric rotary grinding of plaques combined with graft repair in the management of peyronie's disease

Peyronie's Disease (PD) is clinically characterized by the development of localized fibrous plaques, primarily on the tunica albuginea, especially on the dorsal area of the penis. These plaques are the hallmark feature of this condition, resulting in penile curvature, deformity, and painful erections for affected individuals. Although various nonsurgical treatment options exist, their overall effectiveness is limited. As a result, surgical intervention has become the ultimate choice for patients with severe penile curvature deformities and associated erectile dysfunction. Our research team has successfully employed a combined approach involving microscopic electric rotary grinding of the fibrous plaques and the use of tunica vaginalis or bovine pericardium as graft materials for the repairing of the defects of tunica albuginea in the treatment of PD. This approach has consistently yielded highly satisfactory results regarding the restoration of penile shape, with excellent cosmetic results and significantly improved sexual satisfaction. 
This protocol aims to present a comprehensive surgical management strategy utilizing electric rotary grinding of the plaques and repairing the defects of tunica albuginea by using the tunica vaginalis, which represents an optimal surgical strategy for treating PD.

A total of 21 patients were included from January 2021 to May 2023. The patient&#39;s age ranges from 34 to 68 years, with an average of 51.5 &#177; 9.4 years old. Of the total number of patients, 8 (38.1%) had diabetes. A total of 16 patients (76.2%) showed significant simple dorsal curvature of the penis, with a curvature angle of 60-90&#176; and 5 patients (23.8%) presented with complex hourglass-like deformities with both dorsiflexion and lateral curvature, or accompanied by constriction like deformities, with bendin...
