Scrotal Trauma Treatment and Outcomes.

INTRODUCTION: Genitourinary tract injuries have been reported to account for 3% to 10% of trauma patients, and scrotal injuries have been reported to comprise 71% of male genital trauma. Scrotal trauma is particularly prevalent in males 10 to 30 years of age, thus posing a potential threat to fertility. Scrotal trauma can be blunt or penetrating in nature, and the mechanism of trauma can have an impact on the management and outcomes of this type of injury. METHODS: A retrospective chart review of adult patients who presented with scrotal trauma to a single large level I trauma center from January 1, 2000, to June 1, 2022, was conducted to assess the relative occurrence and type of trauma (blunt vs penetrating), as well as differences in the management, duration of hospital stay, and need for orchiectomy between these 2 types of injury. RESULTS: There were 102 patients included in this study, with an average age of 39.5 years (18.7-77.2 years). Fifty-six patients had blunt scrotal trauma, and 46 had penetrating scrotal injury. There was not a statistically significant difference in the percentages of blunt versus penetrating trauma (P < = 0.3729). Patients with penetrating trauma were more likely to be inpatient than those with blunt trauma (69.6% vs 42.9%; P < = 0.013; 95% CI, 0.062-0.473). A total of 61 patients were treated conservatively (44 and 17 patients in the blunt and penetrating trauma groups, respectively). Overall, 41 patients required surgical intervention: 12 who had blunt trauma and 29 who suffered penetrating injury. Surgical treatment was more common for penetrating trauma than for blunt trauma (63.0% vs 21.4%; P <0.0001; 95% CI, 0.220-0.612). Eleven patients underwent orchiectomy - 4 from the blunt trauma group and 7 from the penetrating trauma group; the rate of orchiectomy was not significantly different between the 2 groups. CONCLUSIONS: In this study, blunt scrotal trauma was slightly more common than penetrating injury, but the difference did not reach statistical significance. Blunt scrotal trauma was associated with a higher rate of conservative treatment. Further study is needed to better understand the impact of scrotal trauma on future fertility.

Hyperbaric oxygen treatment in bilateral orchiopexy and post-circumcision haematoma in a thrombocytopenic patient with Noonan syndrome.

Hyperbaric oxygen treatment (HBOT) can be utilised for necrotising soft tissue infections, clostridial myonecrosis (gas gangrene), crush injuries, acute traumatic ischaemia, delayed wound healing, and compromised skin grafts. Our case was a 17-month-old male patient with Noonan syndrome, idiopathic thrombocytopenic purpura, and bilateral undescended testicles. Haematoma and oedema developed in the scrotum and penis the day after bilateral orchiopexy and circumcision. Ischaemic appearances were observed on the penile and scrotal skin on the second postoperative day. Enoxaparin sodium and fresh frozen plasma were started on the recommendation of haematology. Hyperbaric oxygen treatment was initiated considering the possibility of tissue necrosis. We observed rapid healing within five days. We present this case to emphasise that HBOT may be considered as an additional treatment option in patients with similar conditions. To our knowledge, no similar cases have been reported in the literature.

Testicular ischemia secondary to acute epididymitis: A case report.

RATIONALE: Rare side effects of acute epididymitis include testicular infarction and ischemia. Distinguishing them from testicular torsion is challenging, both clinically and radiologically. However, only a few such cases have been reported to date. PATIENT CONCERNS: A 12-year-old child presented with persistent right testicular pain for 3 days. It developed after trauma and was accompanied by gradual swelling and enlargement of the right scrotum, with nausea and vomiting. Scrotal color Doppler ultrasonography demonstrated right epididymitis, right scrotal wall swelling, and right testicular torsion. Routine blood tests revealed leukocyte and neutrophil counts were both above normal. DIAGNOSIS: Scrotal exploration revealed edema and adhesions in all layers of the scrotal wall. The right testicle was pale. The patient was diagnosed with testicular ischemia secondary to acute epididymitis. INTERVENTIONS: The patient underwent simultaneous lower spermatic cord sheath dissection and decompression, testicular sheath reversal, and right testicular fixation. OUTCOMES: Blood flow to the testicles gradually recovered after decompression, as did the color. Postoperatively, the patient's scrotal swelling and pain improved significantly. LESSONS: Despite the rarity of this condition, it is a potentially serious consequence of epididymitis and should be considered when patients experience sudden scrotal pain.

Imaging Penile and Scrotal Trauma: What the Surgeon Needs to Know.

As a complement to computed tomography and ultrasound for the emergency evaluation of penile and scrotal trauma, MR imaging provides unique advantages and anatomic delineation in the acute care setting. Rapid recognition of traumatic injuries helps guide appropriate clinical and surgical care to prevent long-term comorbidities. It is important for the radiologist to understand and identify these findings to optimize patient care in the emergency setting.

Traumatic testicular dislocation: A case report and literature review.

INTRODUCTION: Traumatic testicular dislocation is an uncommon complication of blunt scrotal injury and is easily overlooked because of the presence of other severe accompanying injuries. In most cases, an operation is needed for the prevention of malignant change or infertility. PATIENT CONCERNS AND DIAGNOSIS: We report a case of traumatic testicular dislocation with pelvic fracture and internal bleeding in a 27-year-old male with testis rupture after a motorcycle collision. INTERVENTIONS AND OUTCOMES: He received emergent right radical orchiectomy, and a series of operations for femoral and pelvic fractures were performed after his condition stabilized in the intensive care unit. After 1 month postsurgery, no obvious genitourinary complications were noted. CONCLUSION: We suggest scrotum examination in all trauma patients, particularly if a pelvic injury is suspected or in case of a high risk of a motorcycle collision, to avoid missing the diagnosis and prevent severe complications.

An unusual etiology of a scrotal dog bite injury and review of the literature.

Soft tissue injuries from animal bites are encountered occasionally in rural areas, resulting from attacks by, for example, dogs, wolves, horses, donkeys, and cats. The commonly affected body parts include the face, head and neck, nose, ears, hands, arms, and legs. The traumatic exposure of the external genital organs following an animal bite is a highly rare condition. Dog bite injuries in this area are a clinical condition that requires careful management due to the bacterial density of the oral flora of dogs, and also the potential bac-terial flora in the genital area, resulting in a high risk of infection. Tissue defects following dog bites to the genital area are at high risk of morbidity, and may even result in life-threatening conditions in the event of a major infection. The classical treatment approaches to soft tissue defects resulting from animal bites include wound irrigation, debridement, rabies and tetanus immunoprophylaxis, antibiotic therapy, and reconstruction after the elimination of the infection. Recently, however, the early acute approach seems to have replaced the conventional late period treatment, with studies recommending surgical repair in the early stage where possible. In this article, an unusual etiology of scrotal defect was determined under the light of detailed literature data. The present study reports on a case in which an early repair was made after wound cleaning and care, debridement, and then prophylactic antibiotic therapy, soon after the referring of the case to the hospital. No signs of local or systemic infection were noticed at the wound site during follow-up. Post-op-erative recovery was uneventful and the repair performed on the case had a satisfactory outcome. Based on our clinical experience, we believe that reconstruction accompanied by an early prophylactic antibiotherapy can produce satisfactory outcomes in genital defects caused by animal bites.

Fuel tank injury in a fatal motorcycle accident.

Vehicular trauma is the most common cause of pelvic fractures. In motorcycle collisions, the driver strikes or is struck by a fixed object, and is subjected to blunt trauma and deceleration forces. Injuries around the scrotum and perineum of victims in motorcycle accidents are known as a fuel tank injuries (FTI). We report the case of a 26-year-old male motorcyclist involved in a fatal high-speed head-on collision with a car. At autopsy, purple bruising distributed symmetrically over both hips with scrotal lacerations were found. Partial bowel evisceration through an abdominal lacerated wound, extensive abdominal organ injuries and multiple fractures were also found. Considering the dynamics of the accident and the type of motorcycle he had been riding, the pelvic bruising and the scrotal injury were related to violent deceleration following the impact, leading the driver to slide forward against the fuel tank of the motorcycle.FTI is comparatively rare in motorcycle accidents because it only occurs in cases involving a head-on collision, and most drivers try to swerve or correct their direction just prior to the collision. Nevertheless, the most frequent cause of pelvic injuries in motorcyclists is caused by contact with the vehicles fuel tank during the crash. Forensic pathologists should have a better knowledge of FTIs as they are helpful in understand the dynamics of the accident and in distinguishing the driver from the passenger in two-rider motorcycle crashes.

Blunt Abdominopelvic Trauma Complicated by Traumatic Testicular Dislocation in a 19-Year-Old Male Patient: A Case Report.

CASE: A 19 year-old male patient presented with testicular dislocation after abdominopelvic trauma. During open reduction and internal fixation, consult to urology was placed after discovering the presence of the intra-abdominal testicle. The testicle was repositioned into the scrotum with orchiopexy, and pelvic fixation was completed with 1 sacroiliac percutaneous screw and pubic symphysis fixation. Postoperative recovery was uneventful, and the patient was discharged home on postoperative day 3. CONCLUSION: Testicular dislocation is an uncommon finding after blunt abdominopelvic trauma; hence, it may be overlooked. Prompt diagnosis of testicular dislocation given the need for operative management to preserve testicle viability is crucial.

Thirty-year experience of utility of island groin flap for scrotal defect single-stage reconstruction.

For the last 32years, we have been using island groin flap successfully to cover the scrotal defects in a single stage with good results. This flap utility for single-stage urethral fistula repair was first reported by the senior author in 1987 and was published in Br J Urol.1We have performed single-stage repair of scrotal defects of medium and moderate size with this flap in 25 cases of Fournier's gangrene and in 4 cases of scrotal avulsion injuries due to road traffic accidents. All had good aesthetic results. More than 50% scrotal size defects were treated by a single groin flap alone. In cases with total loss of the scrotum, the groin flap was used along with two superior medial pedicle thigh flaps. Here, we have included cases of single-stage reconstruction of scrotal reconstruction by island groin flap alone. All our patients were operated under spinal anaesthesia. The results were satisfactory for the patients. We conclude from our 30 years of experience of utilizing this vascular island groin flap for a single-stage repair of scrotal defects of moderate size to be a procedure of better choice.

Multivariate analysis of early surgical management factors affecting posttraumatic penoscrotal avulsion injury: a level I trauma center study.

BACKGROUND: To conduct an accurate evaluation of patients presenting with posttraumatic penoscrotal injuries, and to formulate a treatment algorithm based on this assessment. METHODS: We conducted a retrospective chart review study. Patients with penoscrotal defects admitted to our level I trauma center from 2017 to 2019 were evaluated. The Braden scale score was used for wound evaluation and the Korean patient classification system (KPCS) was used for assessment of severity. Univariate and multivariate analyses were performed for potential risk factors associated with early surgical management. RESULTS: In total, there were 58 male patients, and the average Braden scale score was 12.08 ± 2.54, with the scrotum (36.20%), and the penile shaft (32.76%) being popular sites for injuries. The wounds requiring surgical treatment were 20.68% (n = 12), with local flaps (33.33%) being most commonly used. The significant predictors of advanced wounds which required surgical treatment were old age (p = 0.026, odds ratio [OR] 8.238), orthopedic combined injuries (p = 0.044, OR 1.088), intubation (p = 0.018, OR 9.625), restraint (p = 0.036, OR 0.157) and blood transfusion (p < 0.001, OR 2.462). CONCLUSION: In multiple trauma patients, penoscrotal defects caused by high-speed trauma are an important matter of concern. Specifically, patients with combined skeletal injuries or requiring respiratory care were prone to advanced wounds. We proposed a five-category algorithm to manage such patients, which included severity of the patient's condition, respiration, hemodynamic status, comorbidity, and immobilization. Additionally, inter-departmental cooperation and active intervention by plastic surgeons is needed for the comprehensive treatment of such injuries. Trial registration This study was performed in line with the principles of the Declaration of Helsinki. The study and all its protocols were approved by the institutional review board of Ajou Medical Center (approval no. AJIRB-MED-MDB-17-254). The need for informed consent was waived by the institutional review board of our hospital due to the retrospective design of the study.

How common are traumatic injuries to the epididymis? A study of prevalence, imaging appearance, and management implications.

PURPOSE: To evaluate the prevalence of epididymal injuries with scrotal trauma, review imaging appearance, clinical management, and outcomes. METHODS: In this retrospective study, the radiology report database was queried for scrotal ultrasounds containing keywords pertaining to trauma, from 1998 to 2019. Exams with no clinically documented trauma, exams with trauma > 1 year ago, and duplicate exams were excluded. Chart review was conducted for age, trauma mechanism, time interval between trauma and ultrasound, signs of infection, and clinical management. Reports were reviewed to record the presence of scrotal injury, traumatic epididymitis, or epididymal hematoma. Cases with epididymal injury underwent image review. Descriptive statistics, Fisher's exact test, and Mann-Whitney's U test were performed to evaluate for associations between clinical parameters and epididymal injury. RESULTS: Initial search yielded 385 exams. A total of 103 exams met inclusion criteria. Trauma mechanisms included straddle injury (35%), blunt scrotal trauma by ball or other object (29%), assault (28%), penetrating injury (4%), and fall (3%). Sixty-eight patients (66%) had scrotal injury on imaging. Twenty-six (25%) had epididymal injury. Thirteen were isolated to the epididymis, and 13 had associated testicular or extra-testicular findings. There were 12 cases of traumatic epididymitis and 14 epididymal hematomas. All epididymal injuries were managed non-operatively. A total of 7 were prescribed antibiotics, including 1 subject who otherwise had no evidence of infection. CONCLUSION: Epididymal injury is encountered in 25% of scrotal ultrasounds for trauma evaluation. Traumatic epididymitis can be seen in 12%. It is important for radiologists to recognize this entity, as it can be mistaken for infection.

Pediatric Trauma-Induced Testicular Torsion: A Surgical Emergency.

OBJECTIVE: To evaluate the features of testicular torsion (TT) resulting from minor groin trauma and to raise the awareness of trauma-induced testicular torsion (TITT). METHODS: This is a retrospective chart review of patients presenting with TT resulting from minor genital trauma that was performed from January 2010 to December 2018 at a single tertiary care institution. The demographic, clinical, and perioperative characteristics, as well as data on follow-up and complications, were analyzed. RESULTS: Of the 155 patients treated for TT, 15 were included in this study. The average age of the patients was 10.3 years (range: 3.2-13.3 years). All patients experienced a direct scrotal trauma and subsequently presented with an ipsilateral scrotal or testicular pain secondary to the twisted testicle. Six patients were misdiagnosed as having scrotal inflammation or hematoma, and all were initially treated at local hospitals. The mean duration of symptoms before hospitalization was 138 h (range: 5-504 h). The mean degree of torsion was 390° (range: 180-720°). The testicular salvation rate, at 33%, was poor. No serious postoperative complications or recurrences of TT was observed. CONCLUSIONS: TITT is a rare entity and still has delayed diagnosis. This may subsequently lead to a low testicular salvation rate. Emergency surgeons, especially in local hospitals, should be aware of the possibility of TT following testicular trauma in pediatric patients. Improving the parents' awareness regarding TT is also important.

Traumatic testicular rupture: Multimodality imaging with intraoperative correlate.

Traumatic testicular rupture is a rare yet serious condition most commonly seen in penetrating trauma victims (e.g. gunshot wounds or motorcycle collisions) that requires immediate surgical management given its potential complications of hypogonadism and infertility. While ultrasound is the most established modality for diagnosing testicular rupture, trauma patients are usually first evaluated with a trauma protocol computed tomography (CT) exam including the chest, abdomen, and pelvis upon presentation, so it is important to recognize CT findings of testicular injury. We present a novel case in which the suspicion for testicular injury was initially raised based upon CT findings of scrotal hematoma/fluid. These findings were then further characterized with ultrasound and confirmed at surgery. In this case, we provide intraoperative imaging that corresponds clearly to findings seen on both CT and ultrasound.

Managing traumatic testicular dislocations: what we know after two centuries.

Traumatic testicular dislocation (TTD) is a rare consequence of blunt scrotal trauma. A 21-year old gentleman presented with inguinal pain following a motorcycle accident and physical examination revealed absence of both testes within a well-formed scrotal sac with bilateral inguinal swellings. Ultrasonography confirmed viability and location of the testes at the superficial inguinal pouch. He underwent emergent surgical reduction with orchidopexy and was discharged the next day. No evidence of testicular dysfunction or atrophy was noted at follow-up. We reviewed reports of TTDs reported in English over the last two centuries and discuss its occurrence, evolution and management.

The role of multiparametric ultrasound in the diagnosis of paediatric scrotal pathology.

Multiparametric ultrasound (MPUS), combining conventional techniques (greyscale and colour Doppler ultrasound), ultrasound strain elastography, and contrast-enhanced ultrasound (CEUS), has been successfully used in the assessment of adult scrotal pathology. Contrast-enhanced ultrasound can confidently establish testicular tissue vascularity even in the small-volume paediatric testis. Elastography provides further assessment of tissue stiffness, potentially adding useful diagnostic information. In children, ultrasonography is particularly advantageous, being safe, radiation-free and negating the need for sedation or general anaesthesia during the imaging evaluation. In this review article, we aim to familiarise readers with the MPUS scanning protocol used for paediatric scrotal examination and provide an overview of scrotal MPUS features, with particular focus to clinical indications where MPUS may be advantageous over conventional ultrasonography.

Paratesticular colon cancer metastasis in an area of remote trauma.

A 53-year-old man with a history of colon adenocarcinoma and remote scrotal trauma resulting in a palpable nodule. Gradual increase in the size of this lesion over the year prior to his presentation to our clinic prompted scrotal ultrasound that demonstrated a 1.1 cm solid lesion, which appeared to arise from the right epididymal tail. Subsequent positron emission tomography (PET) scan showed intense focal uptake at the base of the right testicle, suspicious for epididymitis versus underlying neoplasm. Scrotal exploration through an inguinal approach revealed a paratesticular mass. Frozen section from an excisional biopsy was positive for adenocarcinoma. Radical orchiectomy was completed. Final pathology returned as metastatic adenocarcinoma involving soft tissue; testis and spermatic cord were without diagnostic abnormalities and surgical margins were not involved. Subsequent analysis was consistent with colorectal origin. The patient recovered well from surgery and is continuing treatment of metastatic colon cancer per the medical oncology team.
