Bladder dysfunction after nerve injury is a variable presentation where the extent of injury determines if the bladder is spastic or atonic. We propose a series of 3 nerve transfers for functional motor restoration of detrusor and external urethral sphincter function, along with sensory reinnervation to the genital dermatome. These transfers would be applicable only in the case of low spinal segment injuries in which sacral nerve root function is lost, but lumbar function is largely preserved. The first transfer of the posterior branch of the obturator nerve to the anterior vesical branch of the pelvic nerve provides a feasible mechanism for patients to initiate detrusor contraction by thigh adduction. Second, external urethra innervation (motor and sensory) may be accomplished by transfer of the primarily motor vastus medialis nerve to the pudendal nerve. Finally, the sensory component of the pudendal nerve to the genitalia may be further enhanced by transfer of the saphenous nerve (sensory) to the pudendal nerve. The main limitations for connecting the nerves in the anterior compartment of the thigh to their pelvic targets are the bifurcation or arborization points of their parent nerve. To ensure the donor nerves had enough length and diameter, we sought to measure these parameters. Twenty-six pelvic and anterior thigh regions were dissected in 13 female cadavers. After the graft and donor sites were clearly exposed and branches identified, the donor nerves were cut at suitable distal sites and then moved into the pelvis for a tensionless anastomosis. Diameters were measured using calipers. The obturator nerve bifurcated 5.5 cm from the entrance of the obturator foramen (SD 1.7 cm, range 2.0-9.0 cm). In every cadaver, we were able to bring the posterior division of the obturator nerve to the anterior vesical branch of the pelvic nerve (located internal to the ischial spine) in a tensionless manner with an excess obturator nerve length of 2.0 cm (SD 1.2 cm, range 0.0-5.0 cm). The distance between the femoral nerve arborization and the anterior superior iliac spine was 9.3 cm (SD 1.8 cm, range 6.5-15.0 cm) and the femoral arborization to the ischial spine was 12.9 cm (SD 1.4 cm, range 10.0-16.0 cm). Diameters were similar between donor and recipient nerves. The chosen donor nerves were long enough and of sufficient caliber for the proposed nerve transfers and a tensionless anastomosis.
