INTRODUCTION In this study we aimed to determine whether high-resolution ultrasound (US) can identify the pudendal nerve and its terminal branches. We also attempted to identify the best approach for visualizing these structures. METHODS Normal anatomy of the pudendal nerve was evaluated in 3 cadavers and 20 healthy volunteers proximally at the level of the ischial spine and distally with low...

we report the case of a three-year-old girl who complained from dysphagia and post-prandial vomiting since she was 6months old. several diagnostic work-ups were performed for her problem. upper gi endoscopy was normal but barium swallow revealed an external pressure effect over upper part of the esophagus (figure 1) and the ct angiography of thoracic aorta showed that this external pressure eff...

BACKGROUND Catheter-related bladder discomfort (CRBD) to an indwelling urinary catheter is defined as a painful urethral discomfort, resistant to conventional opioid therapy, decreasing the quality of postoperative recovery. According to anatomy, the branches of sacral somatic nerves form the afferent nerves of the urethra and bladder triangle, which deriving from the ventral rami of the second...

The pudendal motor system is constituted by striated muscles of the pelvic floor and the spinal motoneurons that innervate them. It plays a role in eliminative functions of the bladder and intestine and in sexual function. Pudendal motoneurons are located in the ventral horn of the caudal lumbar spinal cord and send their axon into the pudendal nerve. In the rat, binding sites for vasopressin a...

A pudendal nerve block is a safe alternative to caudal anaesthesia to provide anaesthesia and/or analgesia for the perineum. It can be considered for a variety of clinical indications in general surgery, obstetrics, urology and chronic pain. The pudendal nerve block has evolved since its first description with respect to techniques (fluoroscopy, neurostimulation and ultrasound) and anatomic ref...

Penile erection is a complex hydraulic process, in which the cardiovascular system (CVS) plays a central role. Erectile dysfunction (ED) is the inability to achieve, and/or maintain penile erection sufficient for satisfactory sexual intercourse, and was previously regarded as part of aging. It is associated with certain diseases and life style habits with a cause-effect relationship, including ...

Arterial priapism is a rare condition in pediatric patients, caused by a fistula between the cavernous artery and the sinusoids of the corpus cavernosum, usually secondary to perineal trauma. We report the case of a 16 year old child with arterial priapism of 5 days duration following a fall astride, successfully treated by superselective arterial embolization with absorbable material. Six mont...

Pudendal nerve entrapment syndrome is an unusual cause of chronic pelvic pain. We experienced a case of pudendal neuralgia associated with a ganglion cyst. A 60-year-old male patient with a tingling sensation and burning pain in the right buttock and perineal area visited our outpatient rehabilitation center. Pelvis magnetic resonance imaging showed the presence of multiple ganglion cysts aroun...

the possibility of abnormal avf was considered and it was confirmed on contrast-enhanced computed tomography (ct), inferring that this modality is not only fast and non-invasive, but also accurate in detecting vascular abnormalities. herein, we report a 42-year-old woman with congenital avf between the external carotid artery and external jugular vein, presenting with palpitation and dyspnea. t...

Background: Fournier's gangrene is a necrotizing fasciitis caused by mixed aerobic and anaerobic bacteria and results in loss of skin and subcutaneous tissue in the perineal area. Coverage of testis varies from closure of the defect primarily, burying inside the thigh, using the remnants of the scrotum for tissue expansion and coverage by flaps. In this manuscript, scrotal advancement flaps and...
