INTRODUCTION}]{I. INTRODUCTION}\par Injuries caused by traffic accidents are responsible for approximately 1.35 million of deaths worldwide and 50 million of non-fatal injuries, most of which the people involved ends up beeing incapacitated. In Brazil, trauma is the third leading cause of overall mortality, with injuries occurring in traffic accounting for 40,000 deaths and more than 150,000 victims being injured with a high degree of severity annually. The incidence is more prevalent in males and young adults, mainly between 15 and 44 years of age. \hyperref[b6]{7,}\hyperref[b7]{8} The kidney is the organ of the genitourinary tract most frequently injured during trauma, which affects up to 10\% of patients hospitalized for abdominal trauma. Renal trauma mainly affects men, in 72-93\% of cases, it is more frequent in the younger population, between 31 and 38 years old, and pathological polycystic kidneys, with tumors or with hydronephrosis secondary to stenosis of the ureteropelvic junction are more prone to trauma, even in lower energy impacts. \hyperref[b0]{1,}\hyperref[b1]{2} London Journal of Medical and Health Research Kidney trauma can occur through three mechanisms: blunt trauma, penetrating trauma and high-speed deceleration. Blunt trauma is responsible for 71-95\% of kidney injuries, the cause of which comes mainly from car accidents and falls. Most kidney injuries are mild, while severe trauma is more prevalent in patients with penetrating trauma than in those who have suffered blunt trauma (27-68\% vs. 4-25\%). \hyperref[b0]{1,}\hyperref[b1]{2} The most used classification of renal trauma is the one proposed by the American Association for the Surgery of Trauma (AAST), revised in 2011, which grades renal injuries from I to V with progressive severity (Table \hyperref[tab_1]{1}). \section[{GRADE II}]{GRADE II}\par Parenchymal laceration < 1 cm in depth, without urinary extravasation, and with non-expanding perirenal hematoma. \section[{GRADE III}]{GRADE III}\par Laceration > 1 cm deep, without collecting system damage and without urinary extravasation. \section[{GRADE IV}]{GRADE IV}\par Laceration in the cortex, medulla and collecting system, possibly with renal artery or vein injury, with contained hemorrhage. \section[{GRADE V}]{GRADE V}\par Kidney is completely fragmented (shattered) and there is avulsion of the renal hilum, which cuts off the organ's blood supply.\par Source: The patient was brought in on a rigid board, with a cervical collar, his airways were patent and there was no pain on palpation of the cervical spine. Upon examination of the chest, expansion was preserved, there was no crackling or pain on palpation, and breath sounds were present bilaterally. Flaccid abdomen, diffusely painful on palpation, without signs of peritoneal irritation, with present bowel sounds and stable pelvis. The pupils were isochoric and isophotoreactive and the Glasgow Coma Scale was 15. At the time of hospital care, the patient was conscious and oriented in time and space, without neurological deficits, hemodynamically stable, reporting left abdominal pain. He denied traumatic brain injury, headache, nausea, vomiting and amnesia.\par The victim denied comorbidities and use of continuous medication and was unaware of previous kidney pathology. He also denied tobacco use but reported moderate alcohol consumption (6 cans per weekend). There was no family history of neoplasms or organ malformations.\par Computed tomography (CT) scans of the skull, chest and abdomen were requested. According to the high-energy trauma protocol established by the service, tomography is available 24 hours a day and is readily accessible, in addition, the patient was hemodynamically stable and needed imaging tests to complement the evaluation, opting for CT instead of FAST (Focused Assessment with Sonography for Trauma).\par The computed tomography report of the abdomen (Figure \hyperref[fig_0]{1}) showed a large retroperitoneal collection adjacent to the left kidney, showing pelvis distention and the "claw sign". He also considered that the possibility of a large adjacent urinoma could be a differential diagnosis, suggesting further investigation. The spleen had normal dimensions, smooth contours and homogeneous attenuation. The exam also showed a small ascites, and there were no other significant alterations, including in the liver, bile ducts, pancreas, adrenals, retroperitoneal lymph nodes or in retroperitoneal vessels, with those cited being found in anatomical aspect and normal dimensions. Chest and skull tomography showed no alterations. From the data found in the anamnesis, physical examination and CT, it was concluded that it was a renal lesion grade V. It wasn't visualized ureteral lesion in the imaging exams due to massive leakage of urine and total distortion of the renal anatomy. Therefore, the patient was referred and underwent exploratory laparotomy, left nephrectomy and distal ureteral ligation. During the surgical procedure, no intraperitoneal free fluid or changes in hollow viscera were found. \section[{London Journal of Medical and Health Research}]{London Journal of Medical and Health Research}\par However, when exploring the left retroperitoneal region, a large amount of urine was drained and a hyperdistended renal capsule was found, in addition to the kidney with a grade V lesion, characterized by complete laceration with avulsion of the hilum and devascularization. In addition, the ureter was patent in the renal hilum, with a complete section 10 cm from the ureteropelvic junction, with a grade V urethral lesion, and a distal ligation was performed. No other injuries were found. The anatomical specimen removed from the patient during surgery is shown in The product of the nephrectomy was sent for anatomopathological study, whose report showed signs of rupture of the renal tissue, with ischemic changes and hydronephrosis, in addition to the absence of malignancy, while in the ureter, focal stenosis and complete section of this were observed, suggesting stenosis of the UPJ (junction pyelic ureter). \section[{III. DISCUSSION}]{III. DISCUSSION}\par In the case observed, the patient's kidney was previously hydronephrotic due to UPJ stenosis, despite not having a previous diagnosis, a fact that increases the risk of more serious injuries and the need for nephrectomy in blunt trauma. \hyperref[b2]{3} However, despite the spleen being the most affected organ in this type of trauma, the patient did not have splenic injury. \hyperref[b3]{4} However, there was ureter trauma, which is extremely uncommon in blunt trauma, whereas ureter injury is usually secondary to iatrogenesis in surgical procedures or due to penetrating trauma, being the most common blunt injury in children with congenital anomalies of the urinary tract, such as UPJ stenosis, which causes hydronephrosis. Ureteral trauma, when identified during surgery, should be treated as early as possible by surgical correction. \hyperref[b8]{9} Kidney trauma should be suspected whenever there is a history of an event with fast deceleration or direct impact on the flank region, back, lower chest and upper abdomen. In these cases, the physical examination may reveal bruises on the flank or upper abdomen, signs of peritoneal irritation, a palpable mass, ecchymosis or abrasions, and rib fractures. In this context, CT with intravenous contrast is the imaging method of choice for hemodynamically stable patients who are victims of both penetrating trauma and blunt trauma, as it allows the definition of the location and severity of the injury, as well as allows the visualization of associated traumas.\par FAST, on the other hand, is useful to demonstrate the presence of free fluid in the cavity, but it is inferior to CT in terms of resolution and ability to define renal trauma. \hyperref[b0]{1,}\hyperref[b5]{6} The management of the patient victim of renal trauma has as priority the control of blood loss, the preservation of the renal tissue and the prevention of complications. While in the past it was thought that the best way to control bleeding London Journal of Medical and Health Research and prevent nephrectomies was through surgery, in recent decades the management of renal trauma has evolved towards prioritizing nonoperative approaches. \hyperref[b0]{1} A recent meta-analysis has shown that the management of non-operative treatment (NOT) is the treatment of choice for low-grade renal trauma, and it should also be considered the first-line treatment of high-grade blunt trauma and penetrating trauma, as it is associated with lower mortality rates, shorter hospital stay hospitalization and similar morbidity rates. \hyperref[b3]{4,}\hyperref[b4]{5} Absolute indications for surgery involve: hemodynamic instability and unresponsiveness to aggressive resuscitation due to renal hemorrhage, grade V vascular injury, and expanding or pulsating perirenal hematoma found during laparotomy performed due to associated injuries to other organs. Relative indications for surgery include, among others: large urine extravasation (spontaneous resolution in most cases), presence of non-viable renal tissue and arterial thrombosis installed for more than 4 hours. \hyperref[b0]{1,}\hyperref[b1]{2} \section[{IV. CONCLUSION}]{IV. CONCLUSION}\par It was possible to conclude that patients with previous renal alterations are more susceptible to more severe injuries, even in blunt trauma, where the most affected organ would be the spleen.\par Injury to the ureter is extremely uncommon in blunt trauma, the main cause of which is iatrogenic. The case described above is atypical because the patient had left kidney injury, which is anatomically close to the spleen, but did not present injury to this organ, but a complete section of the ureter. For the definitive diagnosis, the correlation between data from the anamnesis, physical examination, imaging tests, intraoperative findings and the result of the anatomopathological analysis was essential. \section[{Attachments}]{Attachments} \section[{GRADE II}]{GRADE II}\par Parenchymal laceration < 1 cm in depth, without urinary extravasation, and with non-expanding perirenal hematoma. \section[{GRADE III}]{GRADE III}\par Laceration > 1 cm deep, without collecting system damage and without urinary extravasation. \section[{GRADE IV}]{GRADE IV}\par Laceration in the cortex, medulla and collecting system, possibly with renal artery or vein injury, with contained hemorrhage. \section[{GRADE V}]{GRADE V}\par Kidney is completely fragmented (shattered) and there is avulsion of the renal hilum, which cuts off the organ's blood supply.\par Source: \begin{figure}[htbp] \noindent\textbf{1}\includegraphics[]{image-2.png} \caption{\label{fig_0}Figure 1 :}\end{figure} \begin{figure}[htbp] \noindent\textbf{2}\includegraphics[]{image-3.png} \caption{\label{fig_1}Figure 2 .}\end{figure} \begin{figure}[htbp] \noindent\textbf{2}\includegraphics[]{image-4.png} \caption{\label{fig_2}Figure 2 :}\end{figure} \begin{figure}[htbp] \noindent\textbf{1}\includegraphics[]{image-5.png} \caption{\label{fig_3}Figure 1 :}\end{figure} \begin{figure}[htbp] \noindent\textbf{} \par \begin{longtable}{P{0.7171451355661882\textwidth}P{0.1328548644338118\textwidth}} \multicolumn{2}{l}{\textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore \textunderscore }\\ ABSTRACT\tabcellsep hemodynamically unstable.
