RESUMO
INTRODUCTION AND IMPORTANCE: Renal trauma is a common and associated complication of abdominal trauma. Although there is consensus that most high-grade injuries require surgical exploration, nonoperative management remains a viable approach. We aim to report case reports of four cases of nonoperative isolated high-grade blunt renal trauma in adults, followed by a literature review. CASE PRESENTATION: A 22-year-old female presented to the emergency room (ER) with intermittent fever and associated symptoms of renal trauma, including persistent left flank pain, nausea, and vomiting. Three weeks earlier was diagnosed with left renal trauma AAST Grade IV. She was advised to go to the hospital but was refused admission. Then she came with intermittent fever, and a second abdominal computed tomography (CT) scan showed urinoma. The patient was managed with a Double J (DJ) stent and percutaneous drainage. CLINICAL DISCUSSION: Conservative management is the standard of care for hemodynamically stable patients with AAST grade I to III renal injury, regardless of the mechanism of efficiency. If perinephric fluid collection persists despite interventions such as ureteral stenting or percutaneous nephrostomy drainage, percutaneous drainage may facilitate healing and prevent or treat abscesses. CONCLUSION: Minimal invasive management DJ stent insertion and percutaneous drainage can be used as a treatment for untreated high-grade renal trauma and urinoma as its complication.
RESUMO
INTRODUCTION: Surgical exploration in complete ureteropelvic-junction disruption (CUPJD) is still recommended by many authors. Conservative approach to pediatric renal trauma (RT) includes minimally invasive techniques such as nephrostomy, angioembolization or double-J stent placement. CASE REPORT: A 14-year-old patient with CUPJD was treated conservatively. CT-scan revealed active bleeding of the renal artery and significant urine extravasation. Coil angioembolization and nephrostomy placement were performed. An attempt to place a double-J stent was unsuccessful and surgical reconstruction was scheduled. Before surgery, methylene-blue was injected through the nephrostomy observing blue urine output through urethra. Antegrade pyelogram revealed drainage from the urinoma to the ureter. A new attempt to place an internal-external double-J-stent was successful. After 5 weeks, it was removed with total restoration of the urinary tract. CONCLUSION: Complete urinary tract restoration in some cases of CUPJD following RT is possible through a nonoperative approach. It can be safe and effective, reducing the risk of complications associated with complex surgeries.
INTRODUCCION: Muchos autores siguen recomendando la exploración quirúrgica en casos de avulsión completa de la unión pieloureteral (ACUPU). El abordaje conservador del traumatismo renal (TR) pediátrico incluye técnicas mínimamente invasivas como la nefrostomía, la angioembolización o el catéter doble J. CASO CLINICO: Paciente de 14 años con ACUPU tratada de forma conservadora. El escáner reveló la presencia de una hemorragia activa en la arteria renal, además de una importante extravasación urinaria. Se practicó angioembolización con bobinas y nefrostomía. Se intentó colocar un catéter doble J, sin éxito, por lo que se programó reconstrucción quirúrgica. Antes de la cirugía, se inyectó azul de metileno a través de la nefrostomía, observándose salida de orina azul a través de la uretra. La realización de una pielografía anterógrada reveló la presencia de drenaje desde el urinoma hacia el uréter. El segundo intento de colocar un catéter doble J interno-externo sí resultó fructífero, retirándose al cabo de 5 semanas, con restauración total del tracto urinario. CONCLUSION: La restauración completa del tracto urinario en algunos casos de ACUPU tras TR es factible sin necesidad de recurrir al abordaje quirúrgico. Se trata de un proceso seguro y eficaz que disminuye el riesgo de las complicaciones propias de las cirugías complejas.

In this case report, we discuss a rare incident of avulsion-type renal injury in a 24-year-old male with no significant medical history. The injury occurred during a traffic accident, where he was involved in a direct impact collision between a motorcycle and a vehicle, leading to altered corticomedullary differentiation in the right kidney, a retroperitoneal hematoma, and free fluid in the cavity. The patient underwent successful emergency abdominal surgery, which involved the removal of the damaged kidney due to the severity of the injury. During his postoperative recovery in the ICU, he received extensive care, including sedation, mechanical ventilation, and vasopressor support. Ultimately, he made a successful recovery and was discharged after rehabilitation. This case highlights the complexities involved in managing patients with renal injuries resulting from high-energy impact accidents. It emphasizes the importance of a multidisciplinary approach in treatment, the challenges associated with deciding on surgical intervention, and the significance of rehabilitation in patient recovery. The uniqueness of this case, characterized by its distinct mechanism of injury and the severity of the trauma, contributes to our broader understanding of renal trauma management in the field of trauma medicine. It underscores the need for personalized patient care strategies and emphasizes the effectiveness of surgical interventions in severe cases of renal trauma.
RESUMO
BACKGROUND: Evidence is sparse regarding the incidence or prevalence of renal or genitourinary injuries arising from contact sports. There are currently no World Health Organization or European consensus guidelines relating to the participation in sport for children and young athletes with a solitary (functioning) kidney. PURPOSE: To review the international literature and to make sport-specific recommendations for children and young athletes with a solitary (functioning) kidney participating in sports, based on the overall likelihood of potential renal or genitourinary injury. STUDY DESIGN: Narrative review; Level of evidence, 4. METHODS: A descriptive epidemiological study was conducted of current literature according to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines. Embase, Google Scholar, Cochrane, and PubMed databases were queried from 1975 to 2023, to assess available evidence regarding the prevalence and risk of renal injury through sports participation and guidelines surrounding the participation in sports for children and young athletes with a solitary (functioning) kidney. Methodological quality and certainty of evidence were assessed according to the International Classification of Urological Disease guidelines. RESULTS: A total of 28 publications were identified after database searches and exclusions, comprising 40,889 patients. The majority of papers providing recommendations arose from the United States. Of the recommendations, 79% permitted an unrestricted return to noncontact sports. A return to contact sports is permitted in most instances after physician consultation. CONCLUSION: There is a dearth of good-quality published evidence in the literature relating to sports participation with a solitary (functioning) kidney. Overall, the risk of genitourinary injury in sports is low, and after physician assessment, there is currently no strong evidence to exclude children and young athletes with a solitary (functioning) kidney from full participation in contact and collision sports.
RESUMO
INTRODUCTION: Renal trauma is the most common of urological trauma and accounts for up to 5% of all. The AAST scale is the most widely used to assess renal trauma. This study focuses on high-grade trauma, whose treatment has evolved towards a conservative approach, with techniques such as angioembolization. The aim is to describe the evolution in the management of high-grade renal trauma in all patients treated at La Paz University Hospital from 2001 to 2022. METHODS: A descriptive retrospective study was conducted on patients treated at the hospital. The study was divided into two periods (2001-2010 and 2011-2022). A total of 285 patients with renal trauma were collected, of which 54 were high grade. The main variable is the type of management, conservative (embolization) or interventional through nephrectomy. RESULTS: In the completed series, there was a decrease in radical nephrectomy in high-grade renal trauma from 50% to 13.8% over time, with an increase in embolization from 23,1% to 44,8%. In patients with isolated renal trauma, those treated with embolization increased from 28.6% to 69.2%, while those undergoing radical/partial nephrectomy decreased from 42.8% to 7.69%. CONCLUSION: The management of renal trauma has evolved over the years in our center. The number of patients treated by embolization has increased, while the number of complications and nephrectomies has decreased.
RESUMO
PURPOSE: The aim of the study is to examine the follow-up and treatment results of late renal functions in children with high-grade (Grades 4, 5) renal trauma resulting from blunt abdominal injury. METHODS: The follow-up and treatment reports of 41 patients with renal trauma admitted to our clinic between the years 2005 and 2015 were reviewed retrospectively. RESULTS: Eight of the 41 cases had Grade 1, five had Grade 2, and 12 had Grade 3 renal trauma. The remaining 16 cases (12 of which were Grade 4, four were Grade 5) had high grade renal trauma. Four (25%) patients with high-grade renal trauma were operated (JJ stent placement was performed on one, renorraphy was performed on two, pyeloplasty and urinoma drainage were performed on one), and 12 patients were followed conservatively. In the long-term follow-up (>1 year), Tc-99m mercaptoacetyltriglycine (MAG3) kidney scintigraphy examination of three (30%) patients out of the 10 patients who were followed up conservatively, the affected kidneys were found to be nonfunctional (renal differential function 0%). The mean differential renal function in four patients who underwent surgery was 31% (between 25% and 40%). CONCLUSION: It should be kept in mind that kidneys may become atrophic or non-functional in the late period of follow-up in cases that are followed conservatively due to high-grade renal trauma. There is no standard algorithm or treatment method in the management of high-grade renal trauma. In order to achieve a good outcome, the treatment should be individualized as much as possible.
RESUMO
PURPOSE: This study aimed to identify the characteristics associated with the need for urinary intervention for a blunt renal injury with collection system involvement using a computed tomography (CT) protocol for trauma. MATERIALS AND METHODS: Abdominal CT images of patients with blunt renal injuries from 2016 to 2020 were reviewed. Patients with low-grade renal trauma, non-collecting system involvement, American Association for the Surgery of Trauma grade V shattered kidney, and emergent nephrectomy were excluded. The largest perinephric mass thickness was measured in the axial view using CT, and a cutoff value was obtained using a receiver-operating characteristic curve analysis. Risk factors for further urinary intervention were analyzed. RESULTS: Among the 70 patients included in this study, those with perinephric mass thicknesses < 25 mm (n = 36) had a significantly lower rate of urinary intervention than those with perinephric mass thicknesses ≥ 25 mm (0 vs. 5; p = 0.023). There was no significant difference in the follow-up durations of the groups (19 days vs. 38 days; p = 0.198). More than 90% of the perinephric mass in the < 25 mm group resolved within a median follow-up duration of 38 days, whereas nearly half of the ≥ 25 mm group had a residual perinephric mass during a median follow-up duration of 19 days. CONCLUSION: The initial CT protocol for trauma was useful for predicting the need for further urinary interventions for collecting system injuries. A perinephric mass thickness < 25 mm is predictive of a low likelihood of requiring urinary intervention.

OBJECTIVES: To report pediatric renal trauma experiences at the National Center for Child Health and Development in Japan according to the Japanese Association for the Surgery of Trauma (JAST) classification 2008. METHODS: Medical records were retrospectively reviewed for 45 children younger than 18 years old diagnosed with renal trauma from February 2004 to December 2021, regarding details of external causes, treatments, complications, and injury scales according to the JAST classification 2008. The cases who cannot be classified into the JAST classification 2008 will be categorized into our original type 0. RESULTS: There were 24 males and 21 females with a mean age of 8.5 years. Left kidneys were the predominantly affected side. Blunt injury was involved in every case (mainly falls and traffic accidents). Concomitant organ injuries were found in 13 cases. The injury scales were type Ia (13.3%), II (11.1%), IIIa (13.3%), IIIb (24.4%). Type 0 accounted for 37.8%, which were type 0c (congenital anomalies of the kidney and urinary tract without hematoma and/or laceration of kidney parenchyma) at 11.1% and type 0h (only hematuria and normal radiologic finding) at 26.7%. Treatments were blood transfusion, ureteral stenting, nephrostomy, and no nephrectomy. Complications were pseudoaneurysm, hypertension, and infection. CONCLUSIONS: Nearly 38% of cases cannot be classified into the JAST classification 2008, comprising at least two irrelevant types (type 0c and type 0h ). Accordingly, a pediatric renal injury scale should be established to achieve the precise diagnosis and treatments. However, further studies are still needed.

INTRODUCTION: The anatomical variations between children and adults render pediatric patients more prone to urogenital trauma. However, it is not known for certain whether children are more prone to genitourinary trauma than adults. The aim of the study is to scrutinize the characteristic of pediatric genitourinary trauma at, the largest tertiary hospital in Eastern part of Indonesia. STUDY DESIGN: The design of the study was analytic retrospective gathering medical records of all pediatric patients with urogenital trauma with total sampling. The number of patients, ages, genders, etiology, locations, and management were collected. Data was statistically analyzed using SPSS®, and p < 0.05 was considered statistically significant. RESULTS: We found 13.5 (10-15.5) years as the median age in our 60 samples. Boy (75.00%), renal trauma (56.67%), abdominal and pelvic trauma (96.67%), traffic accident (91.67%), suprapubic catheterization (52.17%), and hemodynamically stable (91.67) was among the majority. We also found that non-operative management was in majority. Statistical analysis demonstrated significant differences for management and grade of injury (p < 0.05). DISCUSSIONS: This is, to the best of our knowledge, the first study of genitourinary injuries in children who were treated at a tertiary hospital in Indonesia during the course of the 7-year research period. The limitations of this study are retrospective character and conducted in single institution. CONCLUSION: The highest incidence of pediatric urogenital trauma is renal trauma due to traffic accident, which often multitrauma. Future prospective multi-center studies should be done to corroborate the results.

INTRODUCTION: Transarterial embolization (TAE) or nephrectomy for patients with blunt renal trauma might result in acute kidney injury (AKI). Thus, we analyzed the American College of Surgeons - Trauma Quality Improvement Program (TQIP) to validate this. We hypothesized that nephrectomy, and not TAE, would be a risk factor for AKI in patients with blunt renal trauma. MATERIAL AND METHODS: Adult patients with blunt injuries from the TQIP between 2017 and 2019 were eligible for inclusion. The patients were divided into three treatment groups: conservative treatment, TAE, and nephrectomy. Multivariable logistic regression was used to clarify the AKI predictors. RESULTS: The study included 12,843 patients, wherein 12,373 (96.3 %), 229 (1.8 %), and 241 (1.9 %) patients were in the conservative, TAE, and nephrectomy groups, respectively. A total of 269 (2.2 %), 20 (8.7 %), and 29 (12.0 %) patients had AKI in the three groups, respectively. Both TAE (odds ratio [OR], 2.367; 95 % confidence interval [CI], 1.372-3.900; p = 0.001) and Nephrectomy (OR, 2.745; 95 % CI, 1.629-4.528; p < 0.001) were a statistically significant predictor for AKI in the multivariable logistic regression. CONCLUSIONS: TAE and nephrectomy were statistically associated with AKI in patients with blunt renal trauma. This result differs from our previous research findings that nephrectomy, but not TAE, was a risk factor for AKI in patients with blunt renal trauma. Further prospective and well-designed research may be needed.

BACKGROUND: Researches on the effect of hemodynamic stabilization on the implantation of conservative management for pediatric high-grade renal traumas are lacking. We aimed to assess the effect of maintaining the initial hemodynamic stability of pediatric patients with grades 3-5 renal trauma on the implementation of the conservative treatment and identify its defining factors. METHODS: A prospective study was performed on pediatric patients with grade 3-5 renal traumas who presented to our hospital during July 2020-June 2022. Hemodynamically stable patients were compared with the unstable patients for clinical characteristics, hemodynamic stabilization, and rates of success of conservative treatment. RESULTS: Forty-three patients were studied, including 26 boys and 17 girls. Of them, 28 (65.1%) patients presented with hemodynamic stability and 15 (34.9%) patients were unstable. Overall, 32 (74.4%) patients achieved and/or maintained hemodynamic stability for conservative management. There was a significant difference in blood pressure level at presentation (p < 0.001). The improvement of the hemodynamic parameters was significant per group and, in comparison (p < 0.001). The size of hematoma was significantly smaller in patients with hemodynamic stability (p = 0.023). Despite the longer (p = 0.033) hospital stay with conservative management, the rates of blood transfusion (p = 0.597) and hospital stay (p = 0.785) were not significantly different between both groups. The rates of nephrectomy and mortality were 14% and 0%, respectively. Blood pressure was independently associated with the achievement of maintained hemodynamic stability for conservative management (p = 0.022). CONCLUSIONS: Hemodynamic stabilization seems to be effective and safe for implementing successful conservative management for pediatric patients with high-grade renal traumas. Blood pressure was the only independent factor of maintaining hemodynamic stability.

Extracorporeal Shock Wave Lithotripsy (ESWL) is an option in the management of urolithiasis. Despite its significant benefits, it has an undesirable outcome such as renal trauma. We report a case of a 38-year-old male with iatrogenic left kidney blunt trauma (AAST Grade IV-V) due to left ESWL, presented initially with unstable hemodynamic and successfully managed conservatively.
RESUMO
PURPOSE: Renal trauma constitutes 0.5% - 5% of all trauma patients, and 10% - 20% of abdominal trauma. It is the most commonly injured organ in the genitourinary tract. Road traffic crash (RTC) is the most common cause. In recent years due to the advances in radiological imaging and endovascular techniques, there has been an increase in the nonoperative management of renal trauma. We investigated a large trauma cohort at a level I trauma centre to evaluate patients' demographics with renal trauma, their management, and the outcomes. METHODS: This was a retrospective analysis of the prospectively collected data of renal trauma patients managed from January 2016 to December 2020. Patients who visited the level I trauma centre in north India with renal trauma were included in this study. Patients who were dead on arrival in the emergency department were excluded. Demographics, mechanism of injury, presence of hemorrhagic shock, associated injuries, complications, length of hospital stay (LOS), discharge, and mortality were recorded. The data were entered in Microsoft Excel 365 and analysed using SPSS version 21. RESULTS: This study collected data from 303 renal trauma patients. Males constituted 86.5% of the patients. Most patients were young, aged from 20 - 40 years. Blunt renal trauma was the predominant mode of injury (n = 270, 89.1%). RTCs (n = 190, 62.7%) and falls from height (n = 65, 21.4%) were the 2 most common mechanisms of injury. Focused assessment with sonography in trauma was positive in 68.4% of patients. Grade III (grading by the American Association for the Surgery of Trauma) renal trauma (30.4%) was the most common grade in our study. The liver (n = 104, 34.3%) and splenic trauma (n = 96, 31.7%) were the most commonly associated injuries. Of the 303 patients, 260 (85.8%) were managed nonoperatively. The mean (SD) of the patients' LOS was 12.5 (6.5) days. There were 25 (8.3%) mortalities during the study period and all of them had associated other injuries. The comparison of LOS of isolated renal trauma group and renal trauma with associated injuries group was not statistically significant (p = 0.322). All the patients who died during the study period had renal trauma with associated other organ injuries. None of the patients with isolated renal trauma died during the study. The outcome comparison between both groups was not statistically significant (p = 0.110). CONCLUSION: Renal trauma predominantly occurs in young males, especially due to RTCs followed by fall from height. Focused assessment with sonography in trauma is not reliable in detecting renal injuries, other diagnostic tools such as contrast enhanced computed tomography torso should be considered in diagnosing and grading these injuries. Renal trauma usually does not occur in isolation. Majority are associated with other abdominal and extra abdominal injuries. Most of the times these injuries can be managed nonoperatively, which can achieve a low mortality. The patients who required surgery had high mortality as compared to patients who managed nonoperatively. These patients who required surgery had either severe renal or extra renal trauma and were in hemorrhagic shock. Renal trauma from this large cohort may contribute to improving the quality of care for patients with renal trauma by obtaining knowledge about the patient's characteristics, management, and outcomes.
RESUMO
Post-traumatic segmental renal infarction is an extremely rare event, especially in case of minor blunt abdominal trauma. While major trauma guidelines are well established, several problems account for the adequate management of minor trauma. Herein, we report a case of minor blunt abdominal trauma determining traumatic thrombosis of the apical renal artery and segmental renal infarction, firstly diagnosed by CEUS in emergency care setting.

Blunt renal injuries in pregnancy are seldom isolated, with resultant renal vascular injury following this type of injury being extremely rare. We present a rare case of complete blockage of the left renal artery about 1 cm from the aortic opening in a second-trimester pregnant woman after she sustained a motor-vehicle-accident. She was managed successfully with NOM. Traumatic renal artery blockage is a rare condition with devastating consequences if missed on imaging. Although blunt renal trauma during pregnancy is a rare condition, NOM has become increasingly popular to reduce morbidity associated with nephrectomy resulting in higher rates of renal salvage.
RESUMO
BACKGROUND: The electrohydraulic high-frequency shock wave (Storz Medical, Taegerwilen, Switzerland) is a new way to create small fragments with frequencies up to 100 Hertz (Hz). This study evaluated the efficacy and safety of this method in a stone and porcine model. MATERIALS AND METHODS: BEGO stones were put in a condom in a specifically designed fixture treated with different modulations to see stone comminution. Standardized ex vivo porcine model with perfused kidneys with 26 upper and lower poles of 15 kidneys was treated with the following modulations: voltage 16-24 kV, capacitor 12 nF and frequency up to 100 Hz. 2000-20,000 shock waves were applied to each pole. The kidneys were perfused with barium sulfate solution (BaSO4) and x-ray was performed to quantify the lesions using pixel volumetry. RESULTS: There was no correlation between the number of shock waves and the powdering degree or the applied Energy and the grade of pulverization in the stone model. Regarding the perfused kidney model, the number of shock waves, applied voltage and frequency had no direct correlation with the occurrence of parenchymal lesions The detected lesions of the renal parenchyma were minimal, technical parameters had no significant impact and the lesions did not differ from the results of former experiments using 1-1.5 Hz in the same model. CONCLUSIONS: High-frequency shock wave lithotripsy can produce small stone fragments to pass in a very short time. The injury to the renal parenchyma is comparable to the results of the conventional SWL using 1-1.5 Hz.

Renal trauma is a serious condition that can result in significant morbidity and mortality, particularly in the case of Grade V injuries with complete avulsion of the renal artery and vein. We report a case of a 22-year-old male who sustained a Grade V renal injury in a motor vehicle accident resulting in total avulsion of the renal artery and vein. The patient underwent immediate surgical exploration with successful nephrectomy and ligation of the renal pedicle. This case reports aims to discuss the management strategies for severe renal injuries and the outcomes associated with this approach.
RESUMO
INTRODUCTION: Unintentional injury is a leading cause of mortality and morbidity in children. There is no consensus on the ideal, discrete management of pediatric renal trauma (PRT). Therefore, management protocols tend to be institution-specific. OBJECTIVE: This study aimed to characterize PRT at a rural level-1 trauma center and subsequently develop a standardized protocol. STUDY DESIGN: A retrospective review of a prospectively maintained database of PRT at a rural level 1 trauma center between 2009 and 2019 was conducted. Injuries were characterized regarding renal trauma grade, associated multi-organ involvement and the need for intervention. The benefit of patient transfer from regional hospitals and length and cost of stay were evaluated. RESULTS: Of 250 patients admitted with renal trauma diagnosis 50 patients <18 years were analyzed. Of those, the majority (32/50, 64%) had low-grade (grade I-III) injuries. Conservative management was successful in all low-grade injuries. Of 18 high-grade PRT, 10 (55.6%) required intervention, one prior to transfer. Among patients with low-grade trauma, 23/32 (72%) were transferred from an outside facility. A total of 13 (26%) patients with isolated low-grade renal trauma were transferred from regional hospitals. All isolated, transferred low-grade renal trauma had diagnostic imaging before transfer and none required invasive intervention. Interventional management of renal injury was associated with a longer median LOS [7 (IQR = 4-16.5) vs 4 (IQR = 2-6) days for conservative management, p = 0.019)] and an increased median total cost of $57,986 vs. $18,042 for conservative management (p = 0.002). DISCUSSION: The majority of PRT, particularly low-grade, can be managed conservatively. A significant proportion of children with low-grade trauma are unnecessarily transferred to higher level centers. Review of pediatric renal trauma at our institution over a decade has allowed us to develop an institutional protocol which we believe allows for safe and effective patient monitoring. CONCLUSION: Isolated, low-grade PRT can be managed conservatively at regional hospitals without needing transfer to a level 1 trauma center. Children with high-grade injuries should be closely monitored and are more likely to need invasive intervention. Development of a PRT protocol will help to safely triage this population and identify those who may benefit from transfer to a tertiary care center.

Having a kidney disease is a major risk factor of renal injury during blunt traumas. We present a case of abdominal blunt trauma due to motor-vehicle accident in a 48 year old male patient. Abdominal computed tomography scan showed a high-volume retroperitoneal hematoma with rupture in the isthmus of the horseshoe kidney with active contrast-enhanced extravasation. He underwent a partial nephrectomy of the left lower pole.
RESUMO
PRACTICAL RELEVANCE: Traumatic injury of the urinary tract may be caused by external accidental trauma or due to iatrogenic injury (typically as a result of catheterisation procedures). Thorough patient assessment and careful attention to patient stabilisation are essential, with diagnosis and surgical repair delayed until the patient is stable, if necessary. Treatment depends on the location and severity of the trauma. If diagnosed and treated promptly, the chance of survival of a patient without other concurrent injuries is good. CLINICAL CHALLENGES: Following accidental trauma, at the initial presentation urinary tract injury can be overshadowed by other injuries, but if left undiagnosed or untreated it can lead to serious morbidity and potentially mortality. Many of the surgical techniques described for management of urinary tract trauma can be associated with complications, and so comprehensive communication with the owners is necessary. PATIENT GROUP: The main population affected by urinary tract trauma is young, adult male cats, owing to their roaming behaviour, as well as their anatomy and the resulting increased risk of urethral obstruction and its associated management. AIMS: This article aims to serve as a guide to all veterinarians who treat cats for the diagnosis and management of urinary tract trauma in cats. EVIDENCE BASE: This review summarises the current knowledge available from a number of original articles and textbook chapters in the literature that cover all aspects of feline urinary tract trauma, and is supported by the authors' own clinical experience.
