Partial mobilisation of the neurovascular bundle for ventral penile curvature correction: A proof-of-concept study

To lift the neurovascular bundle (NVB) is a critical step during dorsal plications for ventral penile curvature correction. Indeed, this procedure may hesitate in nerves and vascular damage. Herein, we present a revolutionary approach of partial NVB mobilisation that avoids dissection among 10 and 2 o’clock positions decreasing the risk of injuring nerves and vessels. We assessed ventral penile curvature after penile degloving, marking the level of maximal bending. Bilateral para urethral incisions were made and the Buck’s fascia carefully mobilised from the tunica albuginea. The mobilisation of NVB was carried until 10 and 2 o’clock, avoiding the area between 10 and 2 o’clock positions, where nerves and vessels are more concentrated. The 10 and 2 o’clock positions correspond also to the dorsal edges of the two cavernosa cylinders, where plications are more effective. Penile straightening after surgery was defined as residual curvature less than 10 degrees. Between 2016 and 2020, we have operated 33 men and 32 boys with ventral penile curvature. The severity of penile curvature was mid (<30 degrees) in 13 (20%) patients, moderate (30–60 degrees) in 33 (51%) patients, and severe (> 60 degrees) in 19 (29%) patients. Penile straight was achieved for all patients. We recorded three haematoma, three glans skin erosion, and one curvature recurrence after 13 months of follow-up. No patient reported erectile dysfunction. This proof-of-concept study shows that partial NVB mobilisation is technically easier and safer compared to complete NVB mobilisation, without compromising the success of surgery. Not applicable
