The pudendal nerve primarily innervates the perineum. This nerve can be gradually stretched and damaged by vaginal deliveries (esp. traumatic births), prolapse of pelvic organs and by pelvic floor descent. This leads to unior bilateral pudendal nerve damage. A direct lesion of the pudendal nerve is rare as it lies deep in the pelvis and is well protected by the pelvic ring. It can be injured ho...

A 12-year-old-boy was admitted to our Medical Imaging Department for scrotal/perineal heamatoma and a painless partial erection after bicycle trauma. He had no other medical history. Doppler US and angiography of penile region were performed. A gray-scale US (axial view, Fig. A)) shows an irregular hypoechoic region within the echogenic cavernous tissue and cavernosal lacuna (arrows). The color...

Contemporary therapies for erectile dysfunction are generally targeted towards older men and universally engage pharmacological and/or device related treatment options. Penile revascularization, using microvascular arterial bypass surgical techniques, is a non-pharmacological, non-device-related, and reconstructive surgical strategy for men with erectile dysfunction that was first described by ...

Chronic pelvic pain can present in various pain syndromes. In particular, interventional procedure plays an important diagnostic and therapeutic role in 3 types of pelvic pain syndromes: pudendal neuralgia, piriformis syndrome, and "border nerve" syndrome (ilioinguinal, iliohypogastric, and genitofemoral nerve neuropathy). The objective of this review is to discuss the ultrasound-guided approac...

The pudendal nerve may be strained either between the sacrospinous and sacrotuberous ligaments at the ischial spine level or within Alcock's canal. Alcock's neuralgia is a rare, painful condition caused by compression of the pudendal nerve within Alcock's canal (pudendal canal) which is an aponeurotic tunnel that cannot be stretched. Patients usually present with intense, unilateral pain involv...

BACKGROUND We assess that pudendal neuralgia is a tunnel syndrome due to a ligamentous entrapment of the pudendal nerve and have treated 400 patients surgically since 1987. We have had no major complication. We conducted a randomized controlled trial to evaluate our procedure. METHODS A sequential, randomized controlled trial to compare decompression of the pudendal nerve with non-surgical tr...

PURPOSE To describe the technique and results of percutaneous puncture of the external carotid artery or one of its branches distal to a surgical arterial ligation. METHODS Forty-three patients underwent 64 embolization attempts by percutaneous arterial puncture distal to an external carotid artery ligation. The punctured arteries were the trunk of the external carotid artery in 31 patients, ...
