On the black slope: analysis of the course of a blunt renal trauma collective in a winter sports region

Purpose The aim of this study was to analyze the injury patterns and clinical course of a winter sport dominated by blunt renal trauma collective. Methods Blunt renal trauma cases (N = 106) treated in a Level 1 Trauma Center in Austria were analyzed. Results We encountered 12.3% grade 1, 10.4% grade 2, 32.1% grade 3, 38.7% grade 4 and 6.6% grade 5 renal traumata classified according to the American Association for the Surgery of Trauma (AAST). The mechanisms of injury (MOI) did not have an influence on the frequency of HG trauma (i.e., grade 4 and 5). No concomitant injuries (CIs) were found in 57.9% of patients. The number of patients without CIs was significantly higher in the sports associated trauma group compared to other MOIs (p < 0.01). In 94.3% the primary treatment was a non-operative management (NOM) including 56.6% conservative, 34.0% endourological, and 3.8% interventional therapies. A follow-up computed tomography (FU-CT) was performed in 81.1%, 3.3 days after trauma. After FU-CT, the primary therapy was changed in 11.4% of cases (grade ≥ 3). Comparing the Hb loss between the patients with grade 3 and 4 kidney trauma with and without revision surgery, we find a significantly increased Hb loss within the first 96 h after the trauma in the group with a needed change of therapy (p < 0.0001). The overall rate of nephrectomy (primary or secondary) was 9.4%. Independent predictors of nephrectomy were HG trauma (p < 0.01), age (p < 0.05), and sex (p < 0.05). The probability of nephrectomy was lower with (winter) sports-associated trauma (p < 0.1). Conclusions Sports-associated blunt renal trauma is more likely to occur isolated, and has a lower risk of severe outcomes, compared to other trauma mechanisms. NOM can successfully be performed in over 90% of all trauma grades.

E-scooter accidents: A rising cause of kidney injury

Introduction: E-scooters recently gained mass expansion, leading to increased use-related injuries, most commonly head trauma, facial, and extremity fractures, while abdominal trauma with kidney involvement is less frequent. Here we present two cases of e-scooter-related high-grade blunt kidney trauma. Case reports: The first case was a 24-year-old male presenting with right abdominal pain after e-scooter autonomous right fall. Focused assessment with sonography for trauma (FAST) was negative, while abdominal CT showed a 3 cm middle-renal laceration. Six-day CT showed minimal urinary extravasation. Neither anemization nor impaired kidney function was observed; the patient was discharged after 9 days. The second case was a 42-year-old male presenting with right flank pain and ipsilateral chest pain after autonomous right fall. Thoracic X-ray revealed multiple rib fractures, while abdominal echography showed a non-homogeneous right kidney with a 1.5 cm perirenal fluid layer. Abdominal CT revealed 2.5 × 4 × 3.5 cm full-thickness middle-upper renal parenchyma laceration and confirmed the perirenal hematoma, while demonstrating two hepatic lesions. A series of CT and ultrasounds confirmed the stability of the aforementioned lesions and reduction of the perirenal hematoma; laboratory findings didn’t show anemization nor impaired renal function. The patient was discharged after 10 days. Discussion: Widespread usage of e-scooter is accompanied by an uptick in traumatic events. The chance of renal trauma increases when lateral fall occurs. In our cases patients were hemodynamically stable, the kidney injury severity was high-grade, and non-operative management was effective. Conclusion: E-scooter accidents could lead to high-grade renal injuries, amenable of non-operative management; these events are expected to raise.

Damage control for renal trauma: the more conservative the surgeon, better for the kidney

Urologic trauma is frequently reported in patients with penetrating trauma. Currently, the computerized tomography and vascular approach through angiography/embolization are the standard approaches for renal trauma. However, the management of renal or urinary tract trauma in a patient with hemodynamic instability and criteria for emergency laparotomy, is a topic of discussion. This article presents the consensus of the Trauma and Emergency Surgery Group (CTE) from Cali, for the management of penetrating renal and urinary tract trauma through damage control surgery. Intrasurgical perirenal hematoma characteristics, such as if it is expanding or actively bleeding, can be a reference for deciding whether a conservative approach with subsequent radiological studies is possible. However, if there is evidence of severe kidney trauma, surgical exploration is mandatory and entails a high probability of requiring a nephrectomy. Urinary tract damage control should be conservative and deferred because this type of trauma does not represent a risk in acute trauma management.

Closed kidney injuries in children

MATERIALS AND METHODS: Within 20 yrs, 76 children aged 28 yrs with kidney trauma were under observation, and 35 of them had associated trauma. Clinical, instrumental, and radiological methods were used in the diagnosis. RESULTS: Of the 76 children with closed kidney trauma, 23 were diagnosed with kidney contusion, 14 with kidney injury with subcapsular hematoma, 16 with kidney injury with rupture of the capsule and perirenal urohematoma, 21 with kidney rupture and damage to the calyxpelvic system, and 2 with traumatic hydronephrotic kidney. Conservative treatment was carried out in 49 (64.4%) children and surgical treatment in 28 (25.6%). In the long term, 28 children with kidney injuries and treated conservatively were examined. Complications were found in nine children: pyeloectasia, deformation of the calyxpelvic system, pyelonephritis, and renal hypertension. Organ-preserving surgery was performed in 22 (28.9%) children and nephrectomy in 5 (6.6%) children. As long-term results: the function of the operated kidneys was satisfactory, some changes occurred in the calyxpelvic systems, and no data for pyelonephritis was found. CONCLUSION: Renal injuries with subcapsular rupture and perirenal urohematoma should be surgically treated to prevent severe long-term complications. In unclear cases, the choice can be a two-stage organ-preserving operation for the so-called crushing of the kidney.

Renal Artery Avulsion from Blunt Kidney Trauma

The kidney is the most frequently injured organ in the urogenital tract with more than 5% of all trauma [1, 2] and 10% of all abdominal trauma [3]. Young men are most commonly affected [4]. The management of renal trauma has shown a trend towards conservative treatment in recent years, even for higher-grade injuries (grade IV and V) [5]. The increased availability and use of interventional radiological procedures for the selective embolization of injured vessels has led to a reduction in open surgical interventions and thus to increased organ preservation [3, 5-7]. Injuries to the kidney vessels, especially the renal artery, are very rare with less than 5% of all abdominal trauma [3].

Potential Use of Wearable Sensors to Assess Cumulative Kidney Trauma in Endurance Off-Road Running

(1) Background: This study aimed to explore wearable sensors′ potential use to assess cumulative mechanical kidney trauma during endurance off-road running. (2) Methods: 18 participants (38.78 ± 10.38 years, 73.24 ± 12.6 kg, 172.17 ± 9.48 cm) ran 36 k off-road race wearing a Magnetic, Angular Rate and Gravity (MARG) sensor attached to their lower back. Impacts in g forces were recorded throughout the race using the MARG sensor. Two blood samples were collected immediately pre- and post-race: serum creatinine (sCr) and albumin (sALB). (3) Results: Sixteen impact variables were grouped using principal component analysis in four different principal components (PC) that explained 90% of the total variance. The 4th PC predicted 24% of the percentage of change (∆%) of sCr and the 3rd PC predicted the ∆% of sALB by 23%. There were pre- and post-race large changes in sCr and sALB (p ≤ 0.01) and 33% of participants met acute kidney injury diagnosis criteria. (4) Conclusions: The data related to impacts could better explain the cumulative mechanical kidney trauma during mountain running, opening a new range of possibilities using technology to better understand how the number and magnitude of the g-forces involved in off-road running could potentially affect kidney function.

A Case of Arteriovenous Fistula After Kidney Trauma Mimicking Tumor

Renal arteriovenous fistulas are rare complications of kidney injury that are usually caused by penetrating or blunt abdominal trauma, percutaneous or open biopsy, or surgery. We report a case of renal arteriovenous fistula after blunt abdominal trauma of a male patient who had traffic accidents. Computed tomography images show arteriovenous fistula lesion mimicking the tumor of the renal pelvis. Through this case, we present how to identify and avoid being confused in diagnosis as well as introduce its clinical manifestations, imaging, and treatment.

FIVE YEARS CHARACTERISTIC OF KIDNEY TRAUMA IN TERTIARY HOSPITAL IN WEST JAVA FROM 2013-2017

Objective: Globally, trauma is one of the leading cause of mortality and morbidity. Kidney is an organ that is often affected in trauma cases in urology. This study aimed to determine the characteristics of cases of kidney trauma treated in Hasan Sadikin Bandung Hospital, and used as part of the database of urogenital trauma in Indonesia. Material & Methods: The secondary data was derived from the medical records of patients with kidney trauma treated at Department of Urology in Hasan Sadikin Hospital Bandung for 5 years period (January 2013 to August 2017), as many as 130 cases. Information used was patients’ gender, mechanism of trauma, grading of kidney trauma, associated injury, management, shock, and outcome after treatment. The data obtained was subsequently recapitulated and processed using a spreadsheet. Results: A total 20489 trauma cases admission in Hasan Sadikin Hospital, 477 cases (2.33%) were urogenital trauma, and 130 of which are cases of kidney trauma (0.63%). The majority of patients with kidney trauma are male (87.7%). Based on the mechanism of trauma, 80% of them were related to traffic accidents, especially in motorcycle traffic accidents, as well as the trauma mechanism of falling from a height (13%). There were 69 patients (53.1%) who had major kidney trauma, and 61 patients (46.9%) had minor kidney trauma; specifically, 42.3% grade I and 21.5% grade V kidney trauma. In general, kidney trauma patients experienced multiple trauma, only 19 cases (14.6%) had not associated injury. Most of patients (63%) did not experience shock, and 87.75% of patients survived after treatment. In the timespan of 5 years, 44 patients underwent McAnninch procedure. Conclusion: In Hasan Sadikin Hospital, most cases of kidney trauma were experienced by men, and were caused by blunt trauma in traffic accidents, especially on motorcyclists. Most patients with kidney trauma experienced multiple trauma.
