Major bladder trauma: the accuracy of cystography

We studied 51 cases of traumatic bladder rupture. Extravasation was noted in 32 cases for which retrograde cystograms were available, including 3 (9 per cent) in which additional infusion of contrast medium was required to demonstrate extravasation. Of the 32 cystograms 4 (13 per cent) showed rupture on the drainage film only. If drainage films and adequate distension of the bladder with contrast medium had been omitted in our study the rate of diagnostic accuracy of the cystogram would have been reduced to 79 per cent. If strict attention is paid to adequate distension of the bladder with contrast material and to obtaining drainage films, diagnostic retrograde cystography for trauma should be almost totally accurate and delays or errors in diagnosis should be rare.     

Blunt bladder trauma: manifestation of severe injury

Twenty-nine patients with bladder injuries requiring operative treatment as a result of blunt trauma are presented. Motor vehicle accidents accounted for 86 per cent of the injuries. Hypotension and gross hematuria were the most prevalent clinical features, 68 per cent and 97 per cent, respectively. All patients had multiple associated injuries requiring operative treatment, average 2.9 per patient. Pelvic fractures occurred in 93 per cent and intra-abdominal injuries in 48 per cent of patients. The majority of ruptures (72%) were intraperitoneal. Mortality, related to associated injuries, was high (34%), attesting to the magnitude of injury sustained by the victim.     

Laparoscopic hernia repair and bladder injury.

BACKGROUND: Bladder injury is a complication of laparoscopic surgery with a reported incidence in the general surgery literature of 0.5% and in the gynecology literature of 2%. We describe how to recognize and treat the injury and how to avoid the problem. CASE REPORTS: We report two cases of bladder injury repaired with a General Surgical Interventions (GSI) trocar and a balloon device used for laparoscopic extraperitoneal inguinal hernia repair. One patient had a prior appendectomy; the other had a prior midline incision from a suprapubic prostatectomy. We repaired the bladder injury, and the patients made a good recovery. CONCLUSION: When using the obturator and balloon device, it is important to stay anterior to the preperitoneal space and bladder. Prior lower abdominal surgery can be considered a relative contraindication to extraperitoneal laparoscopic hernia repair. Signs of gas in the Foley bag or hematuria should alert the surgeon to a bladder injury. A one- or two-layer repair of the bladder injury can be performed either laparoscopically or openly and is recommended for a visible injury. Mesh repair of the hernia can be completed provided no evidence exists of urinary tract infection. A Foley catheter is placed until healing occurs.

Diagnosis and management of bladder injury by trauma surgeons

BACKGROUND: Bladder injuries constitute one of the most common urological injuries involving the lower urinary tract. The methods of diagnosis and management of bladder trauma have been well established and accepted. However, bladder injuries are usually associated with other major injuries, and it is our concern here how bladder injuries have been managed as part of multiple trauma. METHODS: From 1991 to 2000, a total of 51 cases of bladder injury were retrospectively reviewed. The mechanisms of trauma, types of bladder injury, time needed to diagnosis, methods of treatment, and patient outcome, were analyzed. Diagnosis time was defined as the time interval from patient arrival to the establishment of a diagnosis either by image studies or laparotomy. Management followed the general rule that bladder contusions or extraperitoneal ruptures were treated non-operatively, and that those with intraperitoneal rupture or combined rupture underwent operative repair. If bladder injury was noted after the patient left the emergency room (ER), it was defined as a delay diagnosis. The Injury Severity Score (ISS), length of hospital stay, and morbidity were used to evaluate patient outcome. RESULTS: The mean age of all the patients was 31.4 years old, and most of them had sustained an injury from a motor vehicle accident (40 of 51). All but 3 patients had gross hematuria. Ten of the patients underwent emergency laparotomy, and 2 of them underwent emergency neurosurgical procedures, therefore no image studies were performed for these 12 patients. A total of 33 patients underwent abdominal computed tomography (CT), but only 20 were correctly diagnosed, yielding an accuracy rate of 60.6%. There were 3 delay diagnoses, due to either a lack of gross hematuria on presentation or the patient leaving the ER before any bladder injury study could be performed. A retrograde cystogram was performed in 24 patients, with an accuracy rate of 95.9% (23 of 24). The mean diagnosis time of the 48 bladder injuries presented in the ER was 3.2 hours and the time needed to reach a diagnosis was not related to the severity of bladder injury. Those patients who underwent operation immediately did not seem to have a quicker diagnosis. Those patients with a higher injury score (ISS >16), and those patients who suffered from pelvic fracture, stayed in the hospital longer. However, the severity of the bladder injury was not related to the length of hospital stay. There was no bladder-related mortality in our series. CONCLUSIONS: We report our results of dealing with bladder injuries from the point of view of trauma surgeons who treat bladder injury as part of multiple injuries. Although known as a procedure of choice for diagnosis of bladder injury, the retrograde cystogram was performed in fewer than half of the patients (24 of 51), which means it is not feasible in many situations. The patient outcome was determined by the severity of injury of the patient but not by the severity of bladder injury.     

Chondral and osteochondral injuries: mechanisms of injury and repair responses

Acute and repetitive impact and torsional loading of joints can damage the articular surface, causing pain, joint dysfunction and effusions, and in some instances, progressive joint degeneration. These injuries often remain undetected and their incidence, pathogenesis, natural history, and optimal treatment remain poorly understood. Advances in arthroscopy and joint imaging have improved the ability of physicians to identify articular surface injuries, and reports of new methods of promoting restoration of articular surfaces have increased interest in their treatment. Three classes of chondral and osteochondral injuries can be identified based on the type of tissue damage and the repair response: (1) damage to the joint surface that does not cause visible mechanical disruption of the articular surface but does cause chondral damage and may cause subchondral bone injury, (2) mechanical disruption of the articular surface limited to articular cartilage, and (3) mechanical disruption of articular cartilage and subchondral bone. In most instances joints can repair damage that does not disrupt the articular surface if they are protected from further injury. Mechanical disruption of articular cartilage stimulates chondrocyte synthetic activity, but it rarely results in repair of the injury. Disruption of subchondral bone stimulates chondral and bony repair, but it rarely restores an articular surface that duplicates the biological and mechanical properties of normal articular cartilage. The extent and effectiveness of the chondral and osseous repair responses vary with age: in general younger individuals, especially skeletally immature people, have more effective repair of articular surface injuries. To be of value to patients a treatment of an articular surface injury must produce better short- and long-term results than the natural repair response. Thus, before selecting a treatment for a patient with a chondral or osteochondral injury the surgeon should define the type of injury and understand its likely natural history.     

Ureteral trauma: Patterns and mechanisms of injury of an uncommon condition

Background

Traumatic ureteral injuries are uncommon, thus large series are lacking.

Methods

We performed a retrospective analysis of the National Trauma Data Bank (2002-2006).

Results

Of the 22,706 genitourinary injuries, 582 ureteral injury patients were identified (38.5% blunt, 61.5% penetrating). Patients were 84% male, 38% white, and 37% black (mean age, 31 y). Blunt trauma patients had a median Injury Severity Score of 21.5 versus 16.0 for penetrating injury (P < .001). Mortality rates were 9% blunt, and 6% penetrating (P = .166). Penetrating trauma patients had a higher incidence of bowel injuries (small bowel, 46%; large bowel, 44%) and vascular injuries (38%), whereas blunt trauma patients had a higher incidence of bony pelvic injuries (20%) (P < .001).

Conclusions

Ureteral injuries are uncommon, seen in approximately 3 per 10,000 trauma admissions, and occur more in penetrating than in blunt trauma. The most common associated injury for blunt ureteral trauma is pelvic bone fracture, whereas penetrating ureteral trauma patients have more hollow viscus and vascular injuries.     

Evolution of a level I pediatric trauma center: Changes in injury mechanisms and improved outcomes

Background

Trauma is the leading cause of mortality among children, underscoring the need for specialized child-centered care. The impact on presenting mechanisms of injury and outcomes during the evolution of independent pediatric trauma centers is unknown. The aim of this study was to evaluate the impact of our single center transition from an adult to American College of Surgeons–verified pediatric trauma center.

Accuracy and relationship of mechanisms of injury, trauma score, and injury severity score in identifying major trauma

The accuracy of mechanism of injury criteria and trauma scores as triage criteria for identifying major trauma patients has been determined from the experience at one trauma center treating 2,500 patients over a 2 year period. Death of the other occupant of the same vehicle as the patient and patient extrication taking longer than 20 minutes were determined to be sufficiently accurate triage criteria. Trauma scores of 14 or less were more accurate than trauma scores of 12 or less.

Tracheobronchial injury secondary to blunt chest trauma: diagnosis and management

Tracheobronchial injury is an uncommon complication in blunt chest trauma. The typical clinical features include haemoptysis, dyspneoa, and air leak. Tracheobronchial injury occurs after high energy impact and is commonly associated with injuries of other vital organs. If tracheobronchial injury is undetected and left untreated, it may cause persistent air leak which can render ventilation difficult and inefficient. Diagnosis of tracheobronchial injury should be made and confirmed by flexible bronchoscopy. The essence of airway management is to bypass the lesion by means of endobronchial intubation to the healthy bronchus with a single-lumen or double-lumen endotracheal tube. Such manoeuvres can also facilitate surgical access if thoracotomy is indicated. Taking into account the size of the lesion and the resulting respiratory status, surgical reconstruction of the injured airway is often necessary. More severe injury may even require lobectomy or pneumonectomy. Late complications of untreated tracheobronchial injury include bronchial stenosis, recurrent pneumonia and bronchiectasis. Prompt diagnosis and treatment generally lead to good functional recovery.     

Surgical repair of pulmonary vein injury from blunt trauma

Pulmonary vein deceleration injury is rare and patients can be deceptively stable for a period after injury. Quick diagnosis and transfer to the operating theatre is the only way to treat this potentially lethal injury successfully. Techniques of repair are a useful addition to the cardiovascular surgeon’s repertoire.     

Vascular injury associated with extremity trauma: initial diagnosis and management

Vascular injury associated with extremity trauma occurs in <1% of patients with long bone fracture, although vascular injury may be seen in up to 16% of patients with knee dislocation. In the absence of obvious signs of vascular compromise, limb-threatening injuries are easily missed, with potentially devastating consequences. A thorough vascular assessment is essential; an arterial pressure index <0.90 is indicative of potential vascular compromise. Advances in CT and duplex ultrasonography are sensitive and specific in screening for vascular injury. Communication between the orthopaedic surgeon and the vascular or general trauma surgeon is essential in determining whether to address the vascular lesion or the orthopaedic injury first. Quality evidence regarding the optimal fixation method is scarce. Open vascular repair, such as direct repair with or without arteriorrhaphy, interposition replacement, and bypass graft with an autologous vein or polytetrafluoroethylene, remains the standard of care in managing vascular injury associated with extremity trauma. Although surgical technique affects outcome, results are primarily dependent on early detection of vascular injury followed by immediate treatment.     

Pelvic ring injury with urologic trauma: a report of bladder extravasation into the hip joint

A case of blunt trauma is presented with pelvic ring disruption and an extraperitoneal bladder rupture that communicated with the hip joint through an acetabular fracture. Extraperitoneal bladder rupture is usually associated with blunt polytrauma and pelvic ring injuries. Expedient diagnosis and multidisciplinary management are essential to minimize significant early and late complications.     

Ten-year trends in traumatic injury mechanisms and outcomes: A trauma registry analysis

Background

Major trauma: a district general hospital experience

A retrospective review of all patients with major trauma admitted to a busy suburban district hospital was conducted over a 1-year period. Outcome for each patient was assessed using the TRISS system which calculates the probability of survival based on anatomical extent of injury and degree of physiological disturbance at the time of admission. Thirty-nine patients were admitted following major trauma, of whom nine died. Seven of the deaths were in patients with a greater than 50 per cent chance of survival according to the TRISS system. In contrast, four patients survived who had a greater than 50 per cent chance of death. Details of these 11 cases are given. The numbers of patients who were referred to neurosurgeons and cardiothoracic surgeons in regional specialist centres were recorded, as was the relative contribution of general and orthopaedic surgeons in our own hospital. We conclude that, in the absence of specialized trauma centres, a reasonable standard of care for patients who have sustained major trauma can be delivered in a district general hospital.
