The genitofemoral nerve is a branch from the lumbar plexus which results from the union of two branches originating from the anterior rami of the first and second lumbar spinal nerves (Figure 4.14). It perforates the psoas muscle obliquely and then runs on its anterior aspect towards the inguinal ligament. It then divides into two terminal branches, at a variable distance from its origin: The femoral branch (lumboinguinal nerve), which accompanies the external iliac artery, passes behind the inguinal ligament and supplies the skin covering Scarpa’s triangle.The genital branch, which enters the inguinal canal, accompanies the spermatic cord and contributes fibers to the cremaster, the scrotum, and, usually, the skin covering the base of the penis. In the female, the nerve runs close to the round ligament of the uterus and supplies the labius majus (and usually the mons pubis).
Anatomy of the vulva

The innervation of the vulva derives from branches of several nerves, including the ilioinguinal nerve, the genital branch of the genitofemoral nerve, the perineal branch of the lateral femoral cutaneous nerve of the thigh, and the perineal branch of the pudendal nerve.

Patients in both the control and intervention groups were administered spinal anaesthesia. Patients in the intervention group received perineural bupivacaine infiltration in addition to spinal anaesthesia. After spinal anaesthesia was given, all patients underwent Lichtenstein tension-free meshplasty. There was no difference in the type and dosage of local anaesthetic used in spinal anaesthesia. All the surgical procedures in the present study were carried out by a group of 6 surgeons at or above the level of the surgical registrar who are well experienced in performing hernia surgery. Intraoperatively Ilioinguinal, iliohypogastric, and genital branch of the genitofemoral nerve were identified. A total of 2 mL of perineural infiltration of 0.5% bupivacaine was given along these 3 nerves [6].

Pulsed radiofrequency stimulation is a well-established treatment modality for a number of neurogenic and non-neurogenic painful conditions. It is a non-nerve destructive, minimally invasive modality in which electrical pulses are released from the tip of an electrode to create an impulse without causing thermal injury [43]. Unlike ablation procedures, PRF interrupts pain signals through biological changes rather than nerve destruction ultimately reducing pain sensation from the affected area [43]. PRF was investigated in five studies including 99 patients. In the majority of cases the impulses were applied to the ilioinguinal nerve or the genital branch of the genitofemoral nerve with the exception of the study by Rozen and Parvez [31] who performed the procedure on T12, L1–2 nerve roots. The probe is inserted into the desired area through fluoroscopic or US guidance and stimulation is reportedly performed with the following settings: 2–60 V, 40–50 Hz with impulses every 20 ms. The most informative study was that of Hetta et al. [29], who performed a double-blind, sham-controlled, clinical trial in which 70 patients were randomized to receive PRF or sham intervention. The patients were followed with a VAS for pain and 80% of those receiving PRF had >50% reduction in VAS pain score vs 23.3% in the sham group. The other reports were mostly case series [30,31,33], except for a single retrospective study [32], and all reported pain reduction in most of their patients that was maintained for a follow-up of 6–9 months. PRF could be an appealing intervention, especially that it is less invasive than surgery, and can be particularly helpful for neuropathic pain secondary to nerve entrapment originating from previous inguinal surgery.

One should note that, despite the efficacy of PQLB, most patients required rescue analgesia. That could be explained by the fact that the hernial sac is supplied by the genital branch of the genitofemoral nerve (L1–2) which is not covered by that type of block [26–28].
