Grade V renal trauma management: results from the multi-institutional genito-urinary trauma study.

PURPOSE: To investigate management trends for American Association for the Surgery of Trauma (AAST) grade V renal trauma with focus on non-operative management. METHODS: We used prospectively collected data as part of the Multi-institutional Genito-Urinary Trauma Study (MiGUTS). We included patients with grade V renal trauma according to the AAST Injury Scoring Scale 2018 update. All cases submitted by participating centers with radiology images available were independently reviewed to confirm renal trauma grade. Management was classified as expectant, conservative (minimally invasive, endoscopic or percutaneous procedures), or operative (renal-related surgery). RESULTS: Eighty patients were included, 25 of whom had complete imaging and had independent confirmation of AAST grade V renal trauma. Median age was 35 years (Interquartile range (IQR) 25-50) and 23 (92%) had blunt trauma. Ten patients (40%) were managed operatively with nephrectomy. Conservative management was used in nine patients (36%) of which six received angioembolization and three had a stent or drainage tube placed. Expectant management was followed in six (24%) patients. Transfusion requirements were progressively higher with groups requiring more aggressive treatment, and injury characteristics differed significantly across management groups in terms of hematoma size and laceration size. Vascular contrast extravasation was more likely in operatively managed patients though a statistically significant association was not found. CONCLUSION: Successful use of nonoperative management for grade V injuries is used for a substantial subset of patients. Lower transfusion requirement and less severe injury radiologic phenotype appear to be important characteristics delineating this group.

A Contemporary Analysis of Combat-related Urological Injuries: Data From the Department of Defense Trauma Registry.

PURPOSE: There has been little to no literature published on combat-related genitourinary injuries beyond 2013. With the goal of enhancing medical readiness prior to deployment and making recommendations to improve the long-term rehabilitation of service members as they become civilians, we sought to describe the incidence of combat-related genitourinary injuries and interventions from January 1, 2007, to March 17, 2020. MATERIALS AND METHODS: We conducted a retrospective analysis of the Department of Defense Trauma Registry, which is a prospectively maintained database, for the time between 2007 and 2020. We used predefined search criteria to primarily identify any casualties that arrived at a military treatment facility with urological-based injuries. RESULTS: The registry contained 25,897 adult casualties, of which 7.2% sustained urological injuries. The median age was 25. Explosive injuries (64%) and firearms (27%) predominated. The median injury severity score was 18 (IQR 10-29). Most patients survived until hospital discharge (94%). The most frequently injured organs were the scrotum (60%), testes (53%), penis (30%), and kidneys (30%). Massive transfusion protocols were activated in 35% of all patients who sustained a urological injury and accounted for 28% of all protocols between 2007 and 2020. CONCLUSIONS: The incidence of genitourinary trauma persistently increased for both military and civilian personnel as the U.S. remained actively engaged in major military conflicts during this period. Patients with genitourinary trauma in this data set were often associated with high injury severity scores and required an increased number of immediate and long-term resources for survival and rehabilitation.

Complications of surgically treated pelvic ring injuries with associated genitourinary injuries.

OBJECTIVE: Pelvic ring injuries are often associated with vascular and intrapelvic organ injuries including damage to the genitourinary system. The purpose of this study was to examine the relationship between surgically treated pelvic ring injuries and genitourinary injuries. The primary outcome was to determine the rate of post-operative complications including infection, urinary dysfunction, and sexual dysfunction. The secondary outcome was to determine if the time to surgery was associated with post-operative complications. METHODS: Retrospective chart review from September 1, 2015 to December 31, 2019 of patients who sustained a pelvic ring injury which required surgical intervention. All patients with closed triradiate cartilage were included. RESULTS: A total of 115 patients met the inclusion criteria, 12 patients with an associated genitourinary (GU) injury were included in the GU group and 103 without GU injury were placed in the non-GU group. The median (range) age of patients in the GU group was 49.5 years (20, 64) and 48 years (15, 92) in the control group (p = 0.92). Demographic characteristics including age, Injury Severity Score and Elixhauser comorbidity score were similar between groups. Within the GU group, five patients had an injury to their bladder, four to their urethra and three had an injury to their kidney. In the GU group, one patient developed a wound dehiscence and one developed a urinary tract infection with subsequent sepsis (17%), while in the non-GU group, one patient (1%) developed erectile dysfunction (p = 0.028). Regression analysis demonstrated that having concomitant pelvic ring and GU injuries, as well as the number of surgeries were variables associated with post-operative complications, while time to surgery was not. DISCUSSION AND CONCLUSIONS: Pelvic ring injuries with concomitant genitourinary injuries were associated with increased odds of post-operative complications. No differences were noted in complication rates due to the time to surgery between groups.

A Hard Day at Work: An Analysis of Occupational Genitourinary Injuries in the United States Workforce.

OBJECTIVE: To use national data to identify risk factors for occupational genitourinary (GU) injuries and to expose potential workplace safety issues requiring national regulation. MATERIALS AND METHODS: The National Trauma Data Bank was queried to identify all adults who suffered a work-related GU injury from 2007 to 2016. Injury was stratified by individual organ and by organ type: intra-abdominopelvic (IAP) vs external genitalia (EG). Distinct multivariable logistic regression models were used to examine associations between prespecified risk factors and GU injury (organ and type) and to identify predictors of intensive care unit and operating room (OR) transfer. RESULTS: Two thousand one hundred thirty-nine patients (total of 2681 GU injuries), were included. A mean of 1.3 GU organ injuries and 7.6 total injuries were suffered per patient. 72% suffered an IAP GU injury, 23% an EG injury, and 5% suffered both. Patients working in agriculture/forestry/fishing, (OR 2.3, P = .003), manufacturing (OR 1.9, P = .05), and natural resources/mining (OR 2.3, P = .012) were at significantly increased risk of EG injury. The penis and urethra were particularly at-risk in agriculture/forestry/fishing (OR 4.0, P = .005; OR 3.0, P = .002) and the urethra in natural resources/mining (OR 3.4, P = .004). IAP GU injury was a significant predictor of intensive care unit transfer (OR 1.8, P <.001), whereas EG injury was a significant predictor of OR transfer (OR 2.5, P <.001). CONCLUSION: Occupational GU injuries remain a major issue for blue-collar workers. External genitalia are particularly at-risk, and injuries often require emergent surgery. National occupational health agencies need to continue to enhance on-the-job safety for those at-risk.

[New WSES-AAST guidelines on trauma of the urogenital tract-Summary and comments]. / Neue WSES-AAST-Leitlinie zum Trauma des Urogenitaltraktes ­ Zusammenfassung und Kommentar.

Different perspectives exist among the various specialist disciplines on the treatment of trauma patients with injuries of the urogenital tract. The multidisciplinary consensus guidelines of the World Society of Emergency Surgery (WSES) and the American Association for the Surgery of Trauma (AAST), which appeared in autumn 2019, are summarized in this article. They should constitute an aid to making decisions on the optimal treatment of trauma patients with urogenital injuries.

Early morbidity and dose-volume effects in definitive radiochemotherapy for locally advanced cervical cancer: a prospective cohort study covering modern treatment techniques.

PURPOSE: Predicting morbidity for patients with locally advanced cervix cancer after external beam radiotherapy (EBRT) based on dose-volume parameters remains an unresolved issue in definitive radiochemotherapy. The aim of this prospective study was to correlate patient characteristics and dose-volume parameters to various early morbidity endpoints for different EBRT techniques, including volumetric modulated arc therapy (VMAT) and adaptive radiotherapy (ART). METHODS AND MATERIALS: The study population consisted of 48 patients diagnosed with locally advanced cervix cancer, treated with definitive radiochemotherapy including image-guided adaptive brachytherapy (IGABT). Multiple questionnaires (CTCAE 4.03, QLQ-C30 and EORTC QLQ-CX24) were assessed prospectively for patients treated with different EBRT techniques, including online adaptive VMAT. Contouring and treatment planning was based on the EMBRACE protocols. Acute toxicity, classified as general, gastrointestinal (GI) or genitourinary (GU) and their corresponding dose-volume histograms (DVHs) were first correlated by applying least absolute shrinkage and selection operator (LASSO) and subsequently evaluated by multiple logistic binomial regression. RESULTS: The treated EBRT volumes varied for the different techniques with ~2500 cm3 for 3D conformal radiotherapy (3D-CRT), ~2000 cm3 for EMBRACE­I VMAT, and ~1800 cm3 for EMBRACE-II VMAT and ART. In general, a worsening of symptoms during the first 5 treatment weeks and recovery afterwards was observed. Dose-volume parameters significantly correlating with stool urgency, rectal and urinary incontinence were as follows: bowel V40Gy < 250 cm3, rectum V40Gy < 80% and bladder V40Gy < 80-90%. CONCLUSION: This prospective study demonstrated the impact of EBRT treatment techniques in combination with chemotherapy on early morbidity. Dose-volume effects for dysuria, urinary incontinence, stool urgency, diarrhea, rectal bleeding, rectal incontinence and weight loss were found.

Urotrauma Guideline 2020: AUA Guideline.

PURPOSE: The authors of this guideline reviewed the urologic trauma literature to guide clinicians in the appropriate methods of evaluation and management of genitourinary injuries. MATERIALS AND METHODS: The Panel amended the Guideline in 2020 to reflect additional literature published through February 2020. When sufficient evidence existed, the Panel assigned the body of evidence a strength rating of A (high), B (moderate), or C (low) for support of Strong, Moderate, or Conditional Recommendations. In the absence of sufficient evidence, the Panel provided additional information as Clinical Principles and Expert Opinions (See table 1[Table: see text]). RESULTS: The Panel updated a total of six existing statements on renal, ureteral, bladder, urethra, and genital trauma. Additionally, four new statements were added based on literature released since the 2017 amendment. Statement 5b was added based on new evidence for treatment of hemodynamically unstable patients with renal trauma. Statement 20b was added based on new literature for percutaneous or open suprapubic tube placement following pelvic fracture urethral injury. Statements 30a and 30b were also added to provide guidance on ultrasonography for blunt scrotal injuries suggestive of testicular rupture and for performing surgical exploration with repair or orchiectomy for penetrating scrotal injuries respectively. CONCLUSIONS: These evidence-based updates to the AUA Guidelines further inform the treatment of urotrauma.

An analysis of 979 patients with pelvic fractures stratified by the presence or absence of solid organ injury.

BACKGROUND: Pelvic fractures (PF) require high force mechanism and their severity have been linked with an increase in the incidence of associated injuries within the abdomen and chest. Our goal is to assess the impact of solid organ injury (SOI) on the outcome of patients with PF and to identify risk factors predictive of morbidity and mortality among these patients. STUDY DESIGN: We conducted a single-center retrospective review of medical records of patients 16 years or older admitted to our level 1 trauma center with pelvic fracture with and without OI associated from blunt trauma between 1/1/2010-7/31/2015. RESULTS: 979 patients with PF were identified. 261/979 (26.7%) had at least one associated SOI. The grade of the SOI ranged from I to III in 246 patients, grade IV in five patients and grade V in 10 patients with SOI sustained a higher pelvic AIS grade and required a statistically significant greater amount of blood products (BP). Thoracic and urogenital injuries were also more common. The mortality of patients with PF was not affected by the presence of SOI. Increasing age, Injury Severity Score, Glasgow Coma Scale, hypothermia and the amount of BP transfused were predictive of mortality. CONCLUSIONS: The presence of SOI did not affect the outcome of patients with pelvic fracture, although our results may be linked to the limited number of patients with high grade SOI. The degree of pelvic AIS is predictive of associated injuries within the abdomen and chest.

Firework-related genitourinary trauma: a single institution case series.

PURPOSE: The clinical impact of firework-related genitourinary trauma remains unknown. In this study, we aim to characterize injury patterns, interventions, and clinical outcomes of firework-related genitourinary injuries and evaluate the relationship with certain firework types. METHODS: A retrospective case series was conducted for patients treated at a level I trauma center from 2005 to 2019 who experienced firework-related genitourinary trauma. Fifteen patients sustained firework-related genitourinary injuries. Injury patterns, operative interventions, clinical outcomes, as well as details of firework type were examined. RESULTS: Firework-related genitourinary injuries were identified in 15 trauma patients. Mean age was 29.7 years (± 14.3, standard deviation), all (100%) patients were male, and most (11; 73.3%) were Caucasian. Average length of stay (LOS) was 10.5 days, and 4 (26.7%) patients required ICU admission. Ten (66.7%) patients underwent 28 operative interventions (mean 1.9 per patient), 7 (46.7%) of whom underwent 15 urologic specific intervention (mean 1.0 per patient). No injury-related deaths occurred. Considering firework type, 10 (66.7%) patients had mortar or shell-related injuries, while 3 (20.0%) involved firecrackers, and 2 (13.3%) involved bottle rockets. All (100%) patients sustained injuries that occurred with the use of legally obtained fireworks and 11 (73.3%) were active users. CONCLUSIONS: Firework-related genitourinary injuries occurred most frequently in young men, lead to polytrauma with the scrotum and penis being the most common urologic sites, had high operative rates, and were most commonly associated with legally obtained fireworks, specifically mortar and shell fireworks. Further investigation is needed to understand the long-term sequelae of these injuries.

[Research progress on urogenital function preservation in extralevator abdominoperineal resection].

Extralevator abdominoperineal excision (ELAPE) has been suggested to potentially improve oncological outcomes in advanced low rectal cancer patients. However, the urogenital function impairment as one of the main complications deteriorates the quality of life in these patients. The key point to prevent urogenital function impairment is to avoid autonomic nerve injury, including the superior and inferior hypogastric nerve plexus and neurovascular bundle. Three areas should be especially focused during surgery, including the posterolateral aspect of the prostate during the separation of the rectum from prostate, the lateral wall of ischioanal fossa and the area in front of anal canal. Previous presumption supposed that extended resection, though promoting oncologic outcomes, might lead to enlarged injury to surrounding vessels and nerves that deteriorated patients' urogenital function. But recent studies show that postoperative urogenital function outcomes of rectal cancer patients who underwent ELAPE are not inferior to conventional APE after the induction of minimal invasive approaches including laparoscopic and robotic surgery. Their quality of life can be comparable with patients who underwent conventional APE, and are even better in some particular area. Moreover, as further improvement of ELAPE procedure has been made, the concept of individualized ELAPE addressed the importance of personalized surgical procedure based on tumor stage and location, dedicating to avoid injury to vessels and nerves through preserving more surrounding tissues. Urogenital function outcomes, as part of postoperative outcomes, get more and more attention in recent years. We review current studies on urogenital function after ELAPE from anatomy to clinical research, in order to raise surgeons' attention of nerve preservation technique and to improve their understanding of ELAPE procedure.

Occupational traumatic injuries rarely affect genitourinary organs: a retrospective, comparative study.

PURPOSE: To determine the mechanisms of injury associated with occupational injuries (OI) to genitourinary (GU) organs and compare GU OIs with GU non-OIs. METHODS: A single institution, retrospective study was conducted at a level 1 trauma center between 2010 and 2016 of all patients with GU injuries. OI was defined as any traumatic event that occurred in the workplace requiring hospital admission. Types of occupations were recorded in addition to the location of injury, mechanisms of injury, concomitant injuries, operative interventions, total cost, and mortality. GU OI patients were then compared to GU non-OI patients. RESULTS: 623 patients suffered a GU injury, of which 39 (6.3%) had a GU OI. Fall (43%) was the most common mechanism of injury; followed by motor vehicle collision/motorcycle crash (31%), crush injury (18%), and pedestrian struck (8%). The adrenal gland (38%) and kidney (38%) were the most commonly injured organs. There was no difference in mortality (13% GU OI vs. 15% GU non-OI, p = 0.70) or total direct cost ($21,192 ± 28,543 GU OI vs. $28,215 ± 32,332 GU non-OI, p = 0.45). Total costs were decreased with mortality from a GU injury (odds ratio (OR) 0.3, CI 0.26-0.59; p = < 0.001) and increased with higher injury severity scores (OR 1.1, CI 1.09-1.2; p = < 0.0001). Total costs were not affected by OI status. CONCLUSIONS: Occupational GU trauma presents with similar patterns of injury, hospital course, and direct cost as GU trauma that occurs in non-occupational settings.

Pelvic Fractures and Associated Genitourinary and Vascular Injuries: A Multisystem Review of Pelvic Trauma.

OBJECTIVE. Blunt pelvic trauma is associated with injuries to the musculoskeletal, lower genitourinary, and vascular systems, leading to significant morbidity and mortality. This article provides a comprehensive review of these injuries, reviews classification systems that are helpful in predicting prognosis, describes the most appropriate imaging tests for injury detection, and emphasizes the role that interventional radiology plays in the setting of pelvic trauma. CONCLUSION. Blunt pelvic injuries can involve the musculoskeletal, genitourinary, and vascular systems, often concomitantly, making it imperative for radiologists to recognize injury patterns and understand implications for management. Injury classifications can be helpful in determining management and predicting prognosis. Contrast-enhanced CT is the imaging modality test of choice in evaluating pelvic trauma, and protocols should be optimized for best detection of injuries. Transcatheter arterial embolization plays a critical role in stopping acute hemorrhage and improving clinical outcomes.

The spectrum of animal related injuries managed at a major trauma centre in South Africa.

BACKGROUND: Humans come into contact and interact with an array of animals in a number of areas and environments. We set out to review our experience with animal-related injuries in Pietermaritzburg, KwaZulu-Natal, South Africa. METHOD: All patients who sustained an injury secondary to an interaction with an animal in the period December 2012-December 2017 were identified from the Hybrid Electronic Medical Registry (HEMR). RESULTS: There were 104 patients in the study sample. The mean age of patients in the study was 32.8 years, with a range from 1 to 76 years old. 75% (n = 78) were male and 25% (n = 26) female. Out of the 104 animal-related injuries, 67 were blunt trauma, 39 penetrating trauma and 3 a combination of blunt and penetrating trauma. The species causing trauma included dogs (53), horses (29), cows (18), buffalo (1), warthog (1), impala (1) and a single goat (1). The median time from injury to hospitalisation was 46.62 hours (range from 0 to 504 hours). Injuries occurred to the head (n = 32), face (n = 9), neck (n = 32), abdomen (n = 22), urogenital system (n = 6), upper limb (n = 39) and lower limb (n = 39). The Injury Severity Score (ISS) mean for the patients was 8.16, the range 1-4, the median 9 and the standard deviation 6.88. In 49 patients the treatment was non-operative. In the remaining 55 patients, a total of 68 operative procedures were required. Operations included wound debridement/surgical washout (n = 38), laparotomy (n = 9), arterial repair/ligation (n = 8), skin graft (n = 4), craniotomy (n = 5), fasciotomy (n = 2), amputation (n = 1), and placement of an ICP monitor (n = 1). 49 of these operations were for patients with dog bite injuries. The mean hospital stay was 0.13 days with a range of 0-4 days. Four patients were admitted to the Intensive Care Unit (ICU) and two patients died. CONCLUSION: Human interactions with animals may result in injuries which require surgical treatment. The most common animal injury is a dog bite but in the case of the larger domestic farm animals, blunt force type injuries and goring can result in significant injuries which require complex surgical interventions.

Common genitourinary catheters: a systematic approach for the radiologist.

Catheters are commonly used to treat and diagnose urinary tract abnormalities in the pediatric population. This pictorial essay reviews commonly placed genitourinary catheters imaged by radiography, fluoroscopy, computed tomography (CT) and ultrasonography (US). The purpose of the catheter, how the catheter is placed, and the imaging findings associated with appropriately positioned catheters as well as misplaced and displaced catheters are described. It is important for radiologists to recognize common genitourinary catheters, and be familiar with their normal and abnormal positions as displacement is often first recognized by diagnostic imaging.

Genitourinary Injuries Among Female U.S. Service Members During Operation Iraqi Freedom and Operation Enduring Freedom: Findings from the Trauma Outcomes and Urogenital Health (TOUGH) Project.

Introduction: Until recently, female U.S. service members (SMs) have not been permitted to serve in direct combat roles. However, during Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF), a large number of female SMs have been wounded while serving in combat support roles. This included an unprecedented number of women with genitourinary (GU) injuries. No previous studies have reported either the incidence or clinical picture of these injuries. The objective of this study is to describe the epidemiology of GU injuries among female U.S. SMs during OIF/OEF and understand the potential for increased female GU injuries in future conflicts and the long-term sequelae from these injury patterns. Materials and Methods: The Department of Defense Trauma Registry was reviewed to identify all U.S. SMs diagnosed with GU injury from 2001 to 2013. The Department of Defense Trauma Registry includes data for wounded SMs treated at any U.S. combat support hospital, the in-theater equivalent of a civilian trauma center. Female SMs with ICD-9-CM diagnosis codes and/or Abbreviated Injury Scale codes for GU injury were included. Data on all females with GU injury were reviewed, including battle injury (BI) and non-BI. Basic demographic and injury characteristics were reported. Results: Among the 1,463 U.S. SMs diagnosed with GU injury while deployed to OIF/OEF, 20 (1.4%) were female (median age: 25 yr; interquartile range 21-27 yr). Of these, nine were BI (45%) and 11 were non-BI (55%). The distribution of injury location was as follows: renal injuries (n = 12), vulvar injuries (n = 3), vaginal injuries (n = 3), perineal injury (n = 1), and bladder injury (n = 1). Median Injury Severity Score was in the severe range of 21 (interquartile range 6-32), and four women (20%) died of their wounds. Important associated injuries included colorectal (n = 5) and lower extremity amputation(s) (n = 2). The most common mechanism of injury among the nine women with GU BI was improvised explosive device blast (n = 6), followed by other explosions (n = 2) and gunshot wound (n = 1). Mechanisms of GU non-BI varied, including gunshot wound (n = 2), fall (n = 2), fire/flame (n = 1), knife wound (n = 1), unintentional machine injury (n = 1), motor vehicle accident (n = 1), sports injury (n = 1), fight (n = 1), and pedestrian injury (n = 1). Conclusion: Female GU injuries comprise a small portion of all GU injuries sustained during OIF/OEF with the most predominant being renal injury. Now that the ground combat exclusion policy has been lifted, these data can be used as a model for the expected injury patterns in future female combatants. Long-term applications for these data include research and development for personal protective equipment and development of a multidisciplinary approach to long-term comprehensive care following GU trauma.

Incidence and immediate management of genitourinary injuries in pelvic and acetabular trauma: a 10-year retrospective study.

OBJECTIVE: To report the incidence of genitourinary (GU) injuries in pelvic and acetabular (P + A) fractures, to investigate associations between P + A fractures and GU injury patterns, and, as a secondary objective, to evaluate prospectively P + A fracture referrals with regard to adherence to the British Orthopaedic Association Standards for Trauma (BOAST) guidelines over a 12-month period. METHODS: A retrospective review of GU injuries associated with P + A fractures was performed for the period January 2006 to December 2016 in a national pelvic trauma centre in Ireland. Patient demographics, mechanism of injury and details of injuries were recorded. In addition, P + A fracture referrals were prospectively monitored in 2016 and reviewed for adherence to guidelines. RESULTS: The incidence of urological trauma in P + A fractures was 2.4% (n = 28/1 141). The median (range) patient age was 45 (19-85) years and the male to female ratio was 2.1:1. Urethral injuries occurred most frequently (n = 12, 43%), followed by bladder (n = 9, 32%), combined bladder and urethral (n = 3, 11%) and kidney (n = 4, 14%). Bladder and urethral injuries were associated with high-energy pelvic trauma. Renal injuries were associated with acetabular fractures in isolation and in combination with pelvic trauma (P = 0.01). In 2016, there were 175 P + A fracture referrals and 19 patients had suspected urotrauma (visible haematuria, n = 5; non-visible haematuria, n = 2; trauma imaging, n = 11); 9 of these 19 patients had no urological investigations performed. CONCLUSION: In P + A trauma cases GU injuries may be underreported because of inadequate evaluation and diagnostic investigations in these patients. We advocate robust, uniform and guideline-based evaluation of GU injuries in P + A trauma to avoid the significant long-term morbidities that are associated with misdiagnosis.

Contemporary management of high-grade renal trauma: Results from the American Association for the Surgery of Trauma Genitourinary Trauma study.

BACKGROUND: The rarity of renal trauma limits its study and the strength of evidence-based guidelines. Although management of renal injuries has shifted toward a nonoperative approach, nephrectomy remains the most common intervention for high-grade renal trauma (HGRT). We aimed to describe the contemporary management of HGRT in the United States and also evaluate clinical factors associated with nephrectomy after HGRT. METHODS: From 2014 to 2017, data on HGRT (American Association for the Surgery of Trauma grades III-V) were collected from 14 participating Level-1 trauma centers. Data were gathered on demographics, injury characteristics, management, and short-term outcomes. Management was classified into three groups-expectant, conservative/minimally invasive, and open operative. Descriptive statistics were used to report management of renal trauma. Univariate and multivariate logistic mixed effect models with clustering by facility were used to look at associations between proposed risk factors and nephrectomy. RESULTS: A total of 431 adult HGRT were recorded; 79% were male, and mechanism of injury was blunt in 71%. Injuries were graded as III, IV, and V in 236 (55%), 142 (33%), and 53 (12%), respectively. Laparotomy was performed in 169 (39%) patients. Overall, 300 (70%) patients were managed expectantly and 47 (11%) underwent conservative/minimally invasive management. Eighty-four (19%) underwent renal-related open operative management with 55 (67%) of them undergoing nephrectomy. Nephrectomy rates were 15% and 62% for grades IV and V, respectively. Penetrating injuries had significantly higher American Association for the Surgery of Trauma grades and higher rates of nephrectomy. In multivariable analysis, only renal injury grade and penetrating mechanism of injury were significantly associated with undergoing nephrectomy. CONCLUSION: Expectant and conservative management is currently utilized in 80% of HGRT; however, the rate of nephrectomy remains high. Clinical factors, such as surrogates of hemodynamic instability and metabolic acidosis, are associated with nephrectomy for HGRT; however, higher renal injury grade and penetrating trauma remain the strongest associations. LEVEL OF EVIDENCE: Prognostic/epidemiologic study, level III; Therapeutic study, level IV.

Diagnosis and management of 365 ureteric injuries following obstetric and gynecologic surgery in resource-limited settings.

INTRODUCTION: Ureteric injuries are among the most serious complications of pelvic surgery. The incidence in low-resource settings is not well documented. METHODS: This retrospective review analyzes a cohort of 365 ureteric injuries with ureterovaginal fistulas in 353 women following obstetric and gynecologic operations in 11 countries in Africa and Asia, all low-resource settings. The patients with ureteric injury were stratified into three groups according to the initial surgery: (a) obstetric operations, (b) gynecologic operations, and (c) vesicovaginal fistula (VVF) repairs. RESULTS: The 365 ureteric injuries in this series comprise 246 (67.4%) after obstetric procedures, 65 (17.8%) after gynecologic procedures, and 54 (14.8%) after repair of obstetric fistulas. Demographic characteristics show clear differences between women with iatrogenic injuries and women with obstetric fistulas. The study describes abdominal ureter reimplantation and other treatment procedures. Overall surgical results were good: 92.9% of women were cured (326/351), 5.4% were healed with some residual incontinence (19/351), and six failed (1.7%). CONCLUSIONS: Ureteric injuries after obstetric and gynecologic operations are not uncommon. Unlike in high-resource contexts, in low-resource settings obstetric procedures are most often associated with urogenital fistula. Despite resource limitations, diagnosis and treatment of ureteric injuries is possible, with good success rates. Training must emphasize optimal surgical techniques and different approaches to assisted vaginal delivery.

[Special urological traumatology in children and adolescents]. / Spezielle urologische Traumatologie bei Kindern und Jugendlichen.

Isolated injuries of the genitourinary tract are rare, with the kidney being the most frequently affected organ, especially in situations of polytrauma. Overall, the genitourinary tract is involved in approximately 3 % of all children suffering polytrauma accidents. The literature and international guidelines provide clear therapeutic concepts with a consensus on the diagnosis and treatment of renal trauma, both for the treatment of adults and for children and adolescents. However, the most common injuries to the external genitalia in children and adolescents are caused by blunt trauma, abrasion, bruising, and piling. For these forms of injuries there are no general recommendations in literature and guidelines regarding diagnostic or therapeutic procedures, which may be due to the wide variety of origins of the injuries. Consequently, as shown in our sequence of case reports, each type of injury to the external genitourinary system requires an individual evaluation and therapeutic approach.
