Traumatic ectopic dislocation of testis

A Literature Review and Two Case Reports: Is Traumatic Dislocation of the Testes a Surgical Emergency?

Traumatic dislocation of the testes (TDT) is a rare sequela of blunt scrotal and perineal trauma. TDT can easily be overlooked during concomitant trauma due to other injuries, The damage to the testis appears to be not severe in dislocation and may be corrected by repositioning even if it is delayed. However, delayed intervention might be associated with pain and discomfort and may lead to abnormal sperm parameters and possible infertility. The urgency of surgical intervention increases whenever there is associated testicular torsion, rupture, or bilateral testicular TDT. We report two cases of unilateral traumatic testicular dislocation following motorcycle crashes with different presentations and approaches to treatment. We also engage in a review of the relevant literature.

Testicular Dislocation After Unstable Pelvic Ring Injury

Reproductive and genitourinary complications following pelvic ring injuries have been described; however, testicular dislocation is rare and can cause significant morbidity if not managed appropriately. We describe a case of testicular dislocation after pelvic ring injury and outline the subsequent management and outcome, and seek to identify areas of improvement to ensure expedient and appropriate care in the setting of these injuries.

Our case describes a 29-year-old male who presented to a level-one trauma center following a motorcycle collision. An anteroposterior compression type II rotationally unstable pelvic ring was identified on imaging. He was hemodynamically unstable and computed tomography (CT) with angiography was ordered. Arterial extravasation was noted from the bilateral anterior internal iliac arteries, which were subsequently embolized by interventional radiology. However, no concomitant genitourinary injury was identified at the time of CT. After resuscitation, the pelvis was stabilized with an anterior symphyseal plate and bilateral sacroiliac screws. During the anterior pelvic approach, the patient’s dislocated testicle was surprisingly discovered inferior to the pubis. Urology was consulted intra-operatively, and the testicle was successfully relocated. At the final follow-up, the pelvic ring was healed without any noticeable urogenital complication.

While testicular dislocation has been reported in the setting of pelvic ring injury, a paucity of information exists regarding management, implications, and areas for improvement in the identification of these injuries. Therefore, in cases of pelvic ring injury with significant trauma, radiologists, traumatologists, and orthopedic surgeons should adopt a multi-disciplinary approach in diligently attempting to rule out testicular dislocation pre-operatively. Intra-operatively, examination under anesthesia and careful operative technique are important in preventing iatrogenic injury.

Pelvic Fracture Associated with Intrapelvic Dislocation of Testis

Introduction

Intrapelvic testicular dislocation is rare injury with the possibility of missed or delayed diagnosis. Timely diagnosis of intrapelvic testicular dislocation can prevent iatrogenic testicular injury during surgery and its long-term sequel.

Case Report

A 30-year-old male after motorbike accident presented with a pelvic injury with intrapelvic dislocation of testis. Timely and appropriate diagnosis of injuries, specially intrapelvic dislocation of testis, required early orchidopexy and open reduction and internal fixation of the anterior column, leading to excellent outcome.

Conclusion

In cases of polytrauma and pelvic injuries specially motorbike accidents, testicular dislocation should be ruled out before definitive surgery. Adequate communication and co-ordination between orthopedic surgeon, radiologist, and urologist can lead to excellent outcomes.

Conservative management of bilateral traumatic testicular dislocation in a 10-year-old boy

A 10-year-old boy fell from a one-meter-high Jacuzzi ladder in a hot spring facility, landing in a straddle position, and injured his perineum. He visited the emergency room of our hospital immediately after the injury. Magnetic resonance imaging (MRI) revealed a tear of the corpus spongiosum urethra, and compression due to a hematoma. With the hematoma spreading to the scrotum, the testes became inverted and dislocated to the inguinal region on both sides. Without surgery or interventions, the testes descended into the scrotum on the third day after the injury before fibrillation and scarring began. Testicular dislocation by injury is rare and encountered exclusively in children. It is generally treated with surgery to retain testicular function. We selected conservative management, as our patient had a closed injury without testicular torsion, and the testicular dislocation was associated with compression by hematoma, which could possibly recover with regression of the hematoma.

Traumatic Testicular Dislocation Associated with Lateral Compression Pelvic Ring Injury and T-Shaped Acetabulum Fracture

We report a case of a unilateral testicular dislocation to the superficial inguinal region associated with a lateral compression type pelvic ring injury (OTA classification 61-C3.3a2, b2, c3) and left T-shaped acetabulum fracture (OTA classification 62-B2) in a 44-year-old male who was in a motorcycle accident. The testicular dislocation was noted during the emergency department primary survey, and its location and viability were verified with ultrasound. The testicle was isolated during surgical stabilization of the left acetabulum through a Pfannenstiel incision and modified-Stoppa approach and returned through the inguinal canal to the scrotum. In follow-up, the patient did not suffer urologic or sexual dysfunction. All motorcycle collision patients presenting with pelvic ring injuries or acetabulum fractures should be worked up for possible testicular dislocation with a scrotal exam. Advanced imaging and a urologic consult may be necessary to detect and treat these injuries.

Sonography of pediatric blunt scrotal trauma: what the pediatric urologist wants to know

Pediatric blunt scrotal trauma is most often the consequence of sports injury and presents a diagnostic challenge because swelling and pain make a scrotal physical exam difficult. US with color flow and duplex Doppler is the first-line imaging modality with the goal of accurate and timely diagnosis of injury requiring surgery to preserve fertility and hormonal function. US imaging findings following blunt scrotal trauma include hydrocele, hematocele, testicular hematoma, testicular fracture, testicular rupture, compromised perfusion/testicular torsion and testicular dislocation. Importantly, several of these findings may coexist. Our goal is to present the pertinent intrascrotal anatomy, US imaging findings for each testicular injury, and contemporary management for each, with emphasis on what our pediatric urology colleagues need to know for optimal patient care.

Testicular Dislocation After Scrotal Trauma: A Case Report and Brief Literature Review

Traumatic dislocation of the testis is a rare event after blunt trauma of the scrotum or abdominopelvic injury. The diagnosis may be overlooked because of associated major injuries. In this study, we report on an adult who presented with a left traumatic dislocation of the testis after a falling astride injury. A brief literature review is also cited.
