Combat urologic trauma in US military overseas contingency operations

Vascularized composite allotransplantation of the penis: current status and future perspectives

Given the multifunctional role of the penis in daily life, penile loss can be a physically and emotionally devastating injury. Options to restore penile loss have traditionally relied on autogenous free flap, local flaps, and skin grafts. These techniques provide satisfactory outcomes but carry high rates of urologic and prosthesis-related complications. Vascularized composite allotransplantation may offer a novel solution for these patients through reconstruction with true penile tissue. Still, penile transplants pose ethical, logistical, and psychosocial challenges. These obstacles are made more complex by the limited cases detailed in published literature. A review of the literature was conducted to assay current practices for penile reconstruction. Most modern complex penile reconstructions utilize autogenous pedicled or free tissue flaps, which may be harvested from a variety of donor sites. A total of five penile transplants have been described in the literature. Of these, four report satisfactory outcomes. The advent of genital allotransplantation has recently broadened the landscape of treatment for penile loss. Reconstruction using true penile tissue through vascularized penile allotransplantation has the possibility to engender increased penile function, sensation, and overall quality of life.

Penetrating Scrotal Injuries: A War Time Experience in a Civilian Setup

AIM: To present our experience in managing testicular involvement in penetrating scrotal injuries, trying to highlight a possible role for conservative management of selected cases. METHODS: We reviewed retrospectively all-penetrating scrotal injuries presented to Alyarmook teaching hospital for the period between January 2009 and November 2015, including only those injured victims who reached the hospital alive. Patients’ charts reviewed regarding their demographic data including age, status being civilian or military, and married or single. We documented as well the cause of injury (bullets vs. explosive devices), laterality, associated injured organs, and type of management performed whether operative or non-operative conservative approach. Postoperative complications were recorded while in-patient and after a follow-up period of at least 1 month. RESULTS: Thirty-one penetrating scrotal injuries were identified, resulted in 34 injured testicles. The patients’ mean age was 34.35 years (±12.89standard deviation [SD]) (18–70 years). Most of the victims 24 (77.4%) were civilians. Explosive devices were the cause of injury in 23 patients (74.2%), while bullets were the cause in the remaining 8 patients (25.8%). Orchidectomy needed to be done in 17 (50%) testicles, while 11 (32.4%) injured testes were repaired by suturing. Six cases (17.6%) were treated conservatively without any surgical intervention. The overall testicular salvage rate was (50%). Twenty-one patients (68%) had associated injuries, mostly fractures. Complications occurred in 10 (32.2%) patients, including two mortalities. CONCLUSIONS: Management of genitourinary injuries continues to be a challenging task. In our penetrating testicular injured series, we succeeded to salvage 50% of the injured testes. Non -surgical treatment is feasible in selected patients, an approach that needs further study and longer follow-up.

Gunshot wounds to the penis and scrotum: a narrative review of management in civilian and military settings

Gunshot wounds (GSW) to the penis and scrotum are present in two thirds of all genitourinary (GU) trauma, with a growing proportion of blast injuries in the military setting. Depending on the energy of the projectile, the injury patterns present differently for military and civilian GSWs. In this review, we sought to provide a detailed overview of GSWs to the external genitalia, from mechanisms to management. We examine how ballistic injury impacts tissues, as well as the types of injuries that occur, and how to assess these injuries to the external genitalia. If there is concern for injury to the deep structures of the penis or scrotum, operative exploration and repair is warranted. Relevant history and physical examination, role of imaging, and choice of conservative or surgical treatment options in the civilian and military setting are discussed, as well as guidelines for management set forth by the American Urological Association (AUA) and European Association of Urology (EAU).

[Initial experience of renal autotransplantation in a child with ureteric rupture secondary to abdominal blunt trauma]

A 8-year-old child with multiple skeletal injuries after car accident is presented in the article. Extensive right-sided urohematoma with impaired kidney function was diagnosed after 15 days. External drainage of urohematoma, ureteroscopy and examination of the right kidney were consecutively performed within 1.5 months. A complete rupture of the right ureter at the level of pyeloureterostomy was diagnosed. Right kidney autotransplantation with ureteral resection and pyeloureteral anastomosis were performed in 2 months after injury. Duration of surgery was 7.5 hours, cold ischemia - 55 min. Postoperative examination confirmed satisfactory function of the right kidney. This observation is relatively rare and the first in Russia.

Kidney and uro-trauma: WSES-AAST guidelines

Renal and urogenital injuries occur in approximately 10-20% of abdominal trauma in adults and children. Optimal management should take into consideration the anatomic injury, the hemodynamic status, and the associated injuries. The management of urogenital trauma aims to restore homeostasis and normal physiology especially in pediatric patients where non-operative management is considered the gold standard. As with all traumatic conditions, the management of urogenital trauma should be multidisciplinary including urologists, interventional radiologists, and trauma surgeons, as well as emergency and ICU physicians. The aim of this paper is to present the World Society of Emergency Surgery (WSES) and the American Association for the Surgery of Trauma (AAST) kidney and urogenital trauma management guidelines.

Urinary Tract Infections after Combat-Related Genitourinary Trauma

Background: We examined clinical outcomes among combat casualties with genitourinary injuries after blast trauma. Methods: Characteristics, clinical care, urologic complications, and infections for subjects enrolled in the Trauma Infectious Disease Outcomes Study (TIDOS) were collected from Department of Defense (DOD) and Department of Veterans Affairs (VA) sources. Logistic regression identified predictors for urinary tract infections (UTIs) after genitourinary trauma. Results: Among 530 TIDOS enrollees who entered VA care, 89 (17%) sustained genitourinary trauma. The majority of subjects (93%) were injured via a blast and 27% had a dismounted complex blast injury (DCBI). Sexual dysfunction was reported with 36% of subjects, whereas 14% had urinary retention/incontinence and 8% had urethral stricture. Urologic complications were comparable between patients with and without DCBIs. Nineteen (21%) subjects had one or more UTI with a total of 40 unique UTI events (25% during initial hospitalization and 75% during subsequent DOD or VA care). The UTI incidence rate was 0.89 per patient-year during initial hospitalization, 0.05 per patient-year during DOD follow-up, and 0.07 per patient-year during VA healthcare. Subjects with UTIs had a higher proportion of bladder injury (53% vs. 13%; p < 0.001), posterior urethral injury (26% vs. 1%; p = 0.001), pelvic fracture (47% vs. 4%; p < 0.001), soft-tissue infection of the pelvis/hip (37% vs. 4%; p = 0.001), urinary catheterization (47% vs. 11%; p < 0.001), urinary retention or incontinence (42% vs. 6%; p < 0.001), and stricture (26% vs. 3%; p = 0.004) compared with patients with genitourinary trauma and no UTI. Independent UTI risk factors were occurrence of a soft-tissue infection at the pelvis/hip, trauma to the urinary tract, and transtibial amputation. Conclusions: Among combat casualties with genitourinary trauma, UTIs are a common complication, particularly with severe blast injury and urologic sequelae. Episodes of UTIs typically occur early after the initial injury while in DOD care, however, recurrent infections may continue into long-term VA care.

Urethral injury in major trauma

Urethral injury in major trauma is infrequent, with complex problems of diagnosis and treatment. The aims of this study are to determine the incidence and epidemiological factors relating to urethral injury in major trauma, as well as determine if any additional prognostic factors are evident within this cohort of patients. A retrospective review of patients sustaining urethral injury following major trauma was made over a 6-year period, from 2010 to 2015. Quantitative analysis was made using the national trauma registry for England and Wales, the Trauma Audit and Research Network (TARN) database, identifying all patients with injury codes for urethral injury. 165 patients with urethral injuries were identified, over 90% were male, most commonly injured during road traffic accidents and with an associated overall mortality of 12%. Urethral injury in association with pelvic fracture occurred in 136 patients (82%), representing 0.6% of all pelvic fractures, and was associated with double the rate of mortality. Urethral injury was associated with unstable pelvic fractures (LC2, LC3, APC3, VS, CM) but not with a specific pelvic fracture type. This study confirms the rare incidence of this injury in major trauma at 1 per 2 million population per year.

[Management of ureteral injuries]

Ureteral injuries account for less than 3% of genitourinary injuries. Most of them are caused iatrogenically during abdominal surgery. The symptoms are often non-specific and do not aid in diagnosis. The later the injury is detected, the more often complications occur. Therefore, in such situations it is important to consider the possibility of ureteral injury and initiate further diagnostic steps as soon as possible. A variety of diagnostic tests are available. In addition to the direct inspection of the ureters and retrograde ureteropyelography, computed tomography (CT) urography is routinely used. Based on the time of diagnosis as well as the extent and the localization of the injury, the further procedure can be determined. For minor injuries, the insertion of a ureteral splint is usually the treatment of choice. In the case of higher grade damage, operative reconstruction by one of several possible surgical procedures is indicated.

Teleology and Defining Sex

Disorders of sexual differentiation lead to what is often referred to as an intersex state. This state has medical, as well as some legal, recognition. Nevertheless, the question remains whether intersex persons occupy a state in between maleness and femaleness or whether they are truly men or women. To answer this question, another important conundrum needs to be first solved: what defines sex? The answer seems rather simple to most people, yet when morphology does not coincide with haplotypes, and genetics might not correlate with physiology the issue becomes more complex. This paper tackles both issues by establishing where the essence of sex is located and by superimposing that framework onto the issue of the intersex. This is achieved through giving due consideration to the biology of sexual development, as well as through the use of a teleological framework of the meaning of sex. Using a range of examples, the paper establishes that sex cannot be pinpointed to one biological variable but is rather determined by how the totality of one's biology is oriented towards biological reproduction. A brief consideration is also given to the way this situation could be comprehended from a Christian understanding of sex and suffering.

Total penile reconstruction: A systematic review

BACKGROUND

Phalloplasty poses a unique challenge to the plastic and reconstructive surgeon. The development of advanced microsurgical techniques has greatly augmented the range of surgical approaches available.

METHODS

A systematic review of the MEDLINE and Cochrane databases was performed to identify clinical studies of total penile reconstruction published within the last 10 years using the search algorithm: "(phallus or penis or penile) and (reconstruction or phalloplasty or transplant)".

RESULTS

The primary literature search retrieved 1400 articles. After applying inclusion and exclusion criteria, 30 studies were selected for review. The radial forearm free flap is the preferred technique for total phalloplasty; however, other techniques including the fibular osteocutaneous flap, anterolateral thigh flap, latissimus dorsi flap, scapular free flap, and abdominal flap are described. Background, indications, and preoperative and postoperative care are also discussed.

CONCLUSIONS

Total penile reconstruction can provide functional, aesthetic, and psychosocial benefits to the patient. Use of the radial forearm free flap has been proposed as the gold standard; however, the wide range of potential complications associated with phalloplasty warrants an individualized approach to each patient.

Scrotal reconstruction and testicular prosthetics

Scrotal surgery encompasses a wide-variety of surgical techniques for an even wider variety of indications. In this manuscript, we review our indications, techniques, and pit-falls for various reconstructive scrotal surgeries as-well-as surgical tips for placement of testicular prostheses. Penoscrotal webbing (PSW) is an abnormal, often-problematic distal insertion of scrotal skin onto the ventral penile shaft. There are several effective and straightforward techniques used to revise this condition, which include simple scrotoplasty, single- or double-Z-plasty, or the VY-flap scrotoplasty. Reconstruction is also commonly indicated following scrotal skin loss caused by infection, trauma, lymphedema, hidradenitis, and cancer. Although initial management of these conditions often involves scrotal skin removal, repair of expansive scrotal skin loss can be technically difficult and can be accomplished by using one of several skin flaps or skin grafting. Split-thickness skin grafting of scrotal defects can be accomplished easily, and provides durable results.

Epidemiology of Genitourinary Injuries among Male U.S. Service Members Deployed to Iraq and Afghanistan: Early Findings from the Trauma Outcomes and Urogenital Health (TOUGH) Project

PURPOSE

In this study we report the number, nature and severity of genitourinary injuries among male U.S. service members deployed to Operations Iraqi Freedom and Enduring Freedom.

MATERIALS AND METHODS

This retrospective cross-sectional study of the Department of Defense Trauma Registry used ICD-9-CM codes to identify service members with genitourinary injuries, and used Abbreviated Injury Scale codes to determine injury severity, genitourinary organs injured and comorbid injuries.

RESULTS

From October 2001 to August 2013, 1,367 male U.S. service members sustained 1 or more genitourinary injuries. The majority of injuries involved the external genitalia (1,000, 73.2%), including the scrotum (760, 55.6%), testes (451, 33.0%), penis (423, 31%) and/or urethra (125, 9.1%). Overall more than a third of service members with genitourinary injury sustained at least 1 severe genitourinary injury (502, 36.7%). Loss of 1 or both testes was documented in 146 men, including 129 (9.4%) unilateral orchiectomies and 17 (1.2%) bilateral orchiectomies. Common comorbid injuries included traumatic brain injury (549, 40.2%), pelvic fracture (341, 25.0%), colorectal injury (297, 21.7%) and lower extremity amputations (387, 28.7%).

CONCLUSIONS

An unprecedented number of U.S. service members sustained genitourinary injury while deployed to Operation Iraqi Freedom/Operation Enduring Freedom. Further study is needed to describe the long-term impact of genitourinary injury and determine the potential need for novel treatments to improve sexual, urinary and/or reproductive function among service members with severe genital injury.

Penetrating pelvic trauma: Initial assessment and surgical management in emergency

Penetrating pelvic trauma (PPT) is defined as a wound extending within the bony confines of the pelvis to involve the vascular, intestinal or urinary pelvic organs. The gravity of PPT is related to initial hemorrhage and the high risk of late infection. If the patient is hemodynamically unstable and in hemorrhagic shock, the urgent treatment goal is rapid achievement of hemostasis. Initial strategy relies on insertion of an intra-aortic occlusion balloon and/or extraperitoneal pelvic packing, performed while damage control resuscitation is ongoing before proceeding to arteriography. If hemodynamic instability persists, a laparotomy for hemostasis is performed without delay. In a hemodynamically stable patient, contrast-enhanced CT is systematically performed to obtain a comprehensive assessment of the lesions prior to surgery. At surgery, damage control principles should be applied to all involved systems (digestive, vascular, urinary and bone), with exteriorization of digestive and urinary channels, arterial revascularization, and wide drainage of peri-rectal and pelvic soft tissues. When immediate definitive surgery is performed, management must address the frequent associated lesions in order to reduce the risk of postoperative sepsis and fistula.

Improvised explosive device-related lower genitourinary trauma in current overseas combat operations

BACKGROUND

The use of improvised explosive devices (IEDs) has had a profound effect on battlefield trauma in the 21st century. Historically, wounds to the genitourinary (GU) structures have been less common than extremity and penetrating abdominal trauma in combat operations. GU injury incidence, severity, and associated injuries secondary to the use of this weapon in Operations Iraqi and Enduring Freedom has not been described.

METHODS

Data from the Department of Defense Trauma Registry was reviewed for combat-related GU injuries in Operations Iraqi and Enduring Freedom from 2001 to 2011. All wounded US armed service members are included in this database. Subjects were selected by a query of current procedural terminology and DRG International Classification of Diseases-9th Rev. codes related to traumatic injury of the penis, scrotum, testicles, and urethra. A retrospective chart review was performed for each patient to identify the date of injury, the mechanism of injury, and the associated traumatic wounds. Subjects' follow-up records were reviewed until present time or separation from active duty.

RESULTS

A total of 501 soldiers sustained lower GU trauma, with a total of 729 injuries. Of these casualties, 448 (89%) were wounded by IEDs. Dismounted injuries (87%) made up more of the cohort than did vehicular. Specific trauma sites include 149 (20%) penile, 260 (36%) testicular, 284 (39%) scrotal, and 36 (5%) urethral injuries. The 180 limb amputations (36%) and 86 fractures (17%) were the most encountered concomitant skeletal wounds among service members with GU injuries.

CONCLUSION

This is the first review of all lower GU trauma sustained by all US armed service members in current overseas combat operations. Combat-related lower GU trauma is primarily caused by IEDs in the spectrum of complex dismounted blast injuries. The mechanism primarily results in multisystem injury, with isolated GU involvement being uncommon. Continued evaluation of long-term sequelae, including sexual, urinary, and reproductive dysfunction, is needed.

Effectiveness of the combat pelvic protection system in the prevention of genital and urinary tract injuries: An observational study

BACKGROUND

Historically, the incidence of genital and urinary tract (GU) injuries in major conflicts has been approximately 5%. To mitigate the risk of blast injury to the external genitalia, the United States and United Kingdom issued protective overgarments and undergarments to troops deployed in support of Operation Enduring Freedom. These two systems combined constitute the pelvic protection system (PPS). Our hypothesis was that PPS use is associated with a reduction of GU injuries in subjects exposed to dismounted improvised explosive device blast injuries.

METHODS

We identified two groups for comparison: those who were confirmed to have worn the PPS at time of injury (n = 58) and a historical control group who were confirmed as not wearing the PPS (non-PPS) (n = 61). Patients with any level of lower extremity amputation from dismounted improvised explosive device blast mechanism were included. The primary outcome measure was presence of a GU injury on admission. A univariate analysis assessing the strength of association with odds ratios and 95% confidence intervals was performed between the PPS and non-PPS groups.

RESULTS

Mean Injury Severity Score (ISS) was higher in the PPS versus the non-PPS group (26.1 vs. 19.3, p = 0.0012). Overall, 31% of the patients in the PPS group sustained at least one GU injury versus 62.3% in the non-PPS group. The odds ratio of sustaining a GU injury in the PPS group as compared with the PPS group is 0.28 (31% vs. 62.3%; 95 % confidence interval, 0.62-0.12; p < 0.001). The most frequent injures were open scrotal/testes wounds, followed by open penis, and open bladder/urethra injuries.

CONCLUSION

The use of the PPS is associated with a decreased odds ratio of GU injury. Despite a 31% absolute reduction, future work should focus on improved efficiency.

Review of the current management of upper urinary tract injuries by the EAU Trauma Guidelines Panel

CONTEXT

The most recent European Association of Urology (EAU) guidelines on urological trauma were published in 2014.

OBJECTIVE

To present a summary of the 2014 version of the EAU guidelines on upper urinary tract injuries with the emphasis upon diagnosis and treatment.

EVIDENCE ACQUISITION

The EAU trauma guidelines panel reviewed literature by a Medline search on upper urinary tract injuries; publication dates up to December 2013 were accepted. The focus was on newer publications and reviews, although older key references could be included.

EVIDENCE SYNTHESIS

A full version of the guidelines is available in print and online. Blunt trauma is the main cause of renal injuries. The preferred diagnostic modality of renal trauma is computed tomography (CT) scan. Conservative management is the best approach in stable patients. Angiography and selective embolisation are the first-line treatments. Surgical exploration is primarily for the control of haemorrhage (which may necessitate nephrectomy) and renal salvage. Urinary extravasation is managed with endourologic or percutaneous techniques. Complications may require additional imaging or interventions. Follow-up is focused on renal function and blood pressure. Penetrating trauma is the main cause of noniatrogenic ureteral injuries. The diagnosis is often made by CT scanning or at laparotomy, and the mainstay of treatment is open repair. The type of repair depends upon the severity and location of the injury.

CONCLUSIONS

Renal injuries are best managed conservatively or with minimally invasive techniques. Preservation of renal units is feasible in most cases. This review, performed by the EAU trauma guidelines panel, summarises the current management of upper urinary tract injuries.

PATIENT SUMMARY

Patients with trauma benefit from being accurately diagnosed and treated appropriately, according to the nature and severity of their injury.

Testosterone recovery after polytrauma and scrotal injury in patients from Operation Enduring Freedom and Operation Iraqi Freedom

PURPOSE

We examined the long-term natural history of testosterone recovery in patients with complex battle injuries.

MATERIALS AND METHODS

We retrospectively reviewed the charts of patients who participated in Operation Enduring Freedom and Operation Iraqi Freedom, and underwent urological surgical consultation at Walter Reed Army Medical Center, Washington, D.C. or the National Naval Medical Center, Bethesda, Maryland, from 2001 to August 2011. Of the 192 patient charts reviewed 138 (72%) had testosterone values available. The study inclusion criterion of at least 2 testosterone measurements, including 1 made within 40 days of injury, was met by 84 patients (61%) with testosterone data available. Those treated with bilateral orchiectomy were not required to meet this criterion.

RESULTS

Initial patient testosterone after injury in the testosterone recovery group was inversely proportional to the degree of scrotal injury. In patients in whom testosterone recovered to at least 250 ng/dl the recovery occurred a mean of 4.5 months after injury. Patients who required testosterone replacement had lower initial testosterone (p = 0.0063) and lower testosterone velocity (p <0.0001).

CONCLUSIONS

Monitoring the velocity of testosterone recovery is a viable approach in male patients who receive significant genitourinary trauma. In patients in whom testosterone recovered the recovery occurred within a mean of 5 months after injury. It is reasonable to observe patients with scrotal injuries since testosterone may recover in many of them without intervention.

Lower genitourinary trauma in modern warfare: the experience from civil violence in Iraq

BACKGROUND

Reports on genitourinary (GU) trauma during the Iraqi conflict have been limited to battlefield injuries. We sought to characterise the incidence, mechanism of injury, wounding pattern, and management of lower GU injuries sustained in civil violence during the Iraqi war.

PATIENTS AND METHODS

A total of 2800 casualties with penetrating trauma to the abdomen and pelvis were treated at the Yarmouk Hospital, Baghdad from January 2004 to June 2008. Of the casualties 504 (18%) had GU trauma including 217 (43%) with one or more injuries to the lower GU organs.

RESULTS

Among the 217 patients there were 262 lower GU injuries involving the bladder in 128 (48.8%) patients, bulbo-prostatic urethra in 21 (8%), penis in 24 (9.2%), and scrotum in 89 (34%). Injuries to the anterior urethra and genitals were inflicted by Improvised Explosive Devices (IEDs) in 53-67% of cases and by individual firearms in 33-47%, while injuries to the posterior urethra and bladder were inflicted by IEDs in 17-22% of cases and by firearms in 78-83%. All penile wounds were repaired save 3 (12.5%) patients who underwent total penectomy. Of 63 injured testicles 54 (86%) could be salvaged and 9 (14%) required unilateral orchiectomy. The leading cause of death was an associated injury to major blood vessels in 26 (84%) of 31 patients who died.

CONCLUSIONS

Injuries to the anterior urethra and genitals were commonly caused by IEDs, while injuries to the posterior urethra and bladder were usually caused by individual firearms. Testis injury was almost always salvageable. Associated trauma to major blood vessels was the leading cause of death in these casualties.

Urethral and penile war injuries: The experience from civil violence in Iraq

Objective

To determine the incidence, mechanism of injury, wounding pattern and surgical management of urethral and penile injuries sustained in civil violence during the Iraq war.

Patients and methods

In all, 2800 casualties with penetrating trauma to the abdomen and pelvis were received at the Al-Yarmouk Hospital, Baghdad, from January 2004 to June 2008. Of these casualties 504 (18%) had genitourinary trauma, including 45 (8.9%) with urethral and/or penile injuries.

Results

Of 45 patients, 29 (64%) were civilians and 16 (36%) were Iraqi military personnel. The injury was caused by an improvised explosive device (IED) in 25 (56%) patients and by individual firearms in 20 (44%). Of the patients, 24 had penile injuries, 15 had an injury to the bulbar urethra and six had an injury to the posterior urethra. Anterior urethral injuries were managed by primary repair, while posterior urethral injuries were managed by primary realignment in five patients and by a suprapubic cystostomy alone in one. An associated injury to major blood vessels was the cause of death in eight of nine patients who died soon after surgery (P < 0.001).

Conclusion

Urethral and penile injuries were caused by IEDs and individual firearms with a similar frequency. Most of the casualties were civilians and a minority were military personnel. Injuries to the anterior urethra can be managed by primary repair, while injuries to the posterior urethra can be managed by primary realignment. An associated trauma to major blood vessels was the leading cause of death in these casualties.

Assessment of genitourinary trauma in southeastern iran

BACKGROUND

To survey genitourinary (GU) organ injury following general trauma, we performed an epidemiologic study of urogenital injuries in trauma patients referred to our hospital (a teaching hospital affiliated with the Zahedan University of Medical Sciences).

OBJECTIVES

We aimed to assess the epidemiology of urogenital system injuries in southeastern Iran.

PATIENTS AND METHODS

From April 2009 to November 2011, all patients with GU injuries referred to our hospital were studied. The data including age, sex, type of injury, mechanism of trauma, and prognosis of patients was collected and analyzed.

RESULTS

From a total of 3450 patients, 66 (1.91%) had injuries of the urogenital system; 49(74.24%) were male and 17(25.75%) female. The patients' mean age was 23 ± 12 years (range 2 to 75 years). Of these 66 patients, 61 (94.24%) had blunt trauma, and 5 (7.57%) had penetrating trauma. Motor vehicle accidents were the most common cause of trauma (63.63%). The most common injured organs were kidneys in 41 (62.12%) and the bladder in 9 (13.6%); 47 patients (71.21%) had associated intra-abdominal injuries, and 42 (63.63%) had other accompanying injuries; 23(34.84%) patients required surgical intervention. Three patients (4.54%) died due to the severity of injuries (Injury Severity Score > 12).

CONCLUSIONS

In our assessment, blunt trauma including road traffic accidents were the main cause of urogenital injuries. Most patients with urogenital trauma had multiple injuries, and required a multidisciplinary approach for management.

Management of combat-related urological trauma in the modern era

Complex genitourinary injuries--associated with lower-extremity amputation as well as pelvic and abdominal wounding--have emerged as common occurrences in current military combat operations. The nature of combat injuries of the genitourinary tract is varied, as are the strategies used in their management. For example, 5% of all combat injuries include wounds of the urinary system or genitalia. For injuries that are predominantly penetrating in nature, immediate care requires the judicious preservation of viable tissue. Once the patient is stable, urethral, corporal and testicular lacerations are closed primarily, whereas soft tissue injuries are re-approximated in a delayed fashion. Negative-pressure dressings have been a useful aid in wound management; wound coverage is most commonly completed with split-thickness skin grafts and local flaps. Complex penile and urethral reconstructions are often delayed so orthopaedic injuries can heal and the patient can manage activities of daily living. Final reconstruction requires a urologist with a full understanding of reconstructive techniques.

A rare case of paediatric pelvic ring injury with lower urinary tract obstruction secondary to a combat blast mechanism

Paediatric pelvic ring fractures are rare, and typically the result of high-energy mechanisms that yield other potentially fatal visceral and solid organ injuries. Specific pelvic fracture patterns have been associated with injury to the lower urinary tract, with the most severe involving laceration of the bladder or transection of the urethra. We report a unique case of paediatric pelvic ring disruption causing an isolated obstruction of the lower urinary tract without laceration or discontinuity. Although most paediatric pelvic fractures are managed non-operatively, we postulate that significant ring deformity contributing to urinary retention be considered an indication for open surgical treatment.

Current epidemiology of genitourinary trauma

This article reviews recent publications evaluating the current epidemiology of urologic trauma. The authors briefly explain databases that have been recently used to study this patient population and then discuss each genitourinary organ individually, utilizing the most relevant and up-to-date information published for each one. The conclusion of the article briefly discusses possible future research and development areas pertaining to the topic.

Tissue engineering of ureteral grafts by seeding urothelial differentiated hADSCs onto biodegradable ureteral scaffolds

The study is aimed to evaluate the differentiation potential of human adipose-derived stem cells (hADSCs) into urothelial lineage, and to assess possibility of constructing ureteral grafts using the differentiated hADSCs and a novel polylactic acid (PLA)/collagen scaffolds. HADSCs were indirectly cocultured with urothelial cells in a transwell coculture system for urothelial differentiation. After 14 days coculturing, differentiation was evaluated by detecting urothelial lineage markers (cytokeratin-18 and uroplakin 2) in mRNA and protein level. Then the differentiated hADSCs were seeded onto PLA/collagen ureteral scaffolds and cultured in vitro for 1 week. The biocompatibility of the scaffolds was tested by scanning electron microscopy (SEM) and MTT analysis. At last, the cell/scafflod grafts were subcutaneously implanted into 4-week-old female athymic mice for 14 days. The results demonstrated that the hADSCs could be efficiently induced into urothelial lineage by indirect coculture. The differentiated cells seeded onto the PLA/collagen ureteral scaffolds survived up to 7 days and maintained proliferation in vitro, which indicated that the scaffolds displayed good biocompatibility. In vivo study showed that the differentiated cells in the grafts survived, formed multiple layers on the scaffolds and expressed urothelial lineage markers. In conclusion, hADSCs may serve as an alternative cell resource in cell-based tissue engineering for ureteral reconstruction. These cells could be employed to construct a model of ureteral engineering grafts and be effectively applied in vivo, which could be a new strategy on ureteral replacement with applicable potential in clinical research.

Management of urogenital trauma: state of the art

PURPOSE OF REVIEW

The field of urogenital trauma is undergoing constant improvement mainly due to better diagnostic tools, a shift toward standardized treatments and better trauma care. The purpose of this review is to summarize the most relevant studies published within the last 3 years on the subject.

RECENT FINDINGS

Computerized tomography grading of renal trauma is an excellent predictor of the need for surgery and the final renal outcome in these patients, as most patients can be treated conservatively. Computerized tomography cystography has become the standard for the diagnosis of bladder rupture in which the indications for surgical intervention may be changing. The most common urethral trauma is posterior urethral injury due to pelvic fracture. The best results in adults and children are achieved by urethroplasty.

SUMMARY

The diagnosis and treatment of genitourinary trauma is still evolving. The long-term sequels of these injuries may best be treated by urologists expert in urogenital reconstruction. In the future, tissue engineering may have an important place in the treatment of these patients.

Profiling genitourinary injuries in United Arab Emirates

Background:

The epidemiology of genitourinary (GU) organ injury following general trauma is not well-studied especially in the Middle East.

Patients and Methods:

All patients with GU injuries from the Trauma Registry of Al-Ain Hospital were studied. The registry data was prospectively collected from March 2003 to March 2006.

Results:

Out of 2573 patients in the registry, 22 had GU injuries (incidence: 0.9%, 2.0 per 100,000 inhabitants per year). Road traffic collision was the most frequent mechanism of injury (50% of all cases). 41% of injuries were renal. In 73% of patients, GU injuries were associated with other organ injuries, the most frequent of which were injuries to the other abdominal and pelvic organs (94%). The mean Injury Severity Score, mean total hospital stay, the percentage of patients who required intensive care unit (ICU) admission were higher in patients with GU injuries compared to non-GU patients (17.1 vs. 5.5 (P 0.001), 15.4 vs. 9.2 days (P 0.040) and 43% vs. 8%, (P 0.0001), respectively.

Conclusions:

The incidence of trauma-related GU injuries in the current study appears to be comparable to those reported from the West. Patients with GU organ injuries tend to have more severe trauma compared to other patients. Road traffic collision was the most common mechanism of injury and the kidney was the most frequently injured organ.

Gunshot wounds to the scrotum: a large single-institutional 20-year experience

Study Type - Therapy (case series) Level of Evidence 4 What's known on the subject? and What does the study add? Penetrating trauma to the scrotum often requires operative intervention, with testicular salvage only possible when enough testicular tissue can be re-approximated in the traumatic setting. The present report represents the largest series of gunshot wound trauma to the scrotum in the literature. Further, it validates recommendations of the European Association of Urology guidelines on urological trauma that advocate operative intervention due to minimal rates of patient morbidity and the inherent limitations of scrotal ultrasonography in discerning testicular compromise.

OBJECTIVE

To report our 20-year experience of gunshot wounds (GSWs) to the scrotum and outline the management of this traumatic injury.

PATIENTS AND METHODS

We queried our institutional database for patients presenting with GSWs to the scrotum between 1985 and 2006. All patients underwent the standard trauma evaluation upon presentation, including physical examination of the external genitalia. Management was dictated by the presence or absence of a penetrating injury to the scrotum and associated traumatic injuries. Nonoperative and operative management of traumatic injury to the scrotum were used. Testicular salvage was performed when anatomically feasible. If testicular salvage was not feasible, an orchiectomy was performed.

RESULTS

Scrotal exploration was performed in 91 (94%) patients while six (6%) patients were treated nonoperatively. Testicular injury was found in 44 (48%) patients undergoing exploration, six (7%) of whom had bilateral testicular injuries, which gave a total of 50 injured testicles. Of the injured testicles, 24 (48%) could not be salvaged and required orchiectomy, while 26 (52%) were debrided and repaired. The most common associated genitourinary (GU) injuries were to the corpora cavernosum (n= 20 [21%]) and urethra (n= 10 [10%]). Soft tissue injury of the extremities occurred in 54 patients (56%), representing the most common non-GU-associated injury. Postoperative complications occurred infrequently: one patient (1%) returned for abscess drainage and one (1%) for haematoma evacuation.

CONCLUSIONS

The present report confirms that any patient with a penetrating injury to the scrotum should undergo immediate scrotal exploration. A low clinical suspicion for performing additional studies to rule out associated urethral and/or penile injury is clinically warranted. Testicular loss occurs in ≈50% of injured testicles.
