Urologic injuries in the Gulf War

Military genitourinary injuries: past, present, and future

Genitourinary (GU) injuries among military service members are as old as war itself. The frequency and clinical picture of GU injuries sustained in conflicts over the ages have evolved along with the constantly changing nature of combat. In this review, we discuss changing trends in the diagnosis and management of GU injuries over the past century and introduce areas of innovation which could impact the care of casualties who sustain GU trauma in the future.

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.

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.

Introduction to biodegradable polylactic acid ureteral stent application for treatment of ureteral war injury

OBJECTIVE

• To study the operability and effectiveness of a biodegradable ureteral stent for clinical treatment of ureteral war injury using a canine model.

MATERIALS AND METHODS

• A device was designed and employed to generate firearm fragment wounds in unilateral ureters (on randomly chosen sides) of nine beagles (Group A). The wounded ureters were then debrided and sutured. • Intravenous pyelography (IVP) and radioactive renography were performed 40, 80 and 120 days postoperatively. In Group B, firearm fragment wounds were made to the bilateral ureters in nine beagles. A polylactic acid stent was placed unilaterally (on a randomly chosen side) whereas the ureter on the other side was debrided and sutured without stenting. • Both IVP and radioactive renography were performed 40, 80 and 120 days postoperatively. The operability and effectiveness of the biodegradable ureteral stent were studied thereafter.

RESULTS

• In Group A, hydronephrosis and hydroureter occurred and worsened postoperatively on the wounded sides in all nine beagles. The ratio of the renal partial concentration indices (RPCI) between the kidneys (unwounded side : wounded side) increased. • The ratio of the kidney washout half-time between the kidneys (unwounded side : wounded side) decreased. In Group B, neither hydronephrosis nor hydroureter was found postoperatively in the stented ureters but both occurred in the unstented ureters in all nine beagles. • The ratio of RPCI between kidneys (stented side : unstented side) increased whereas the kidney washout half-time ratio between the stented and unstented sides decreased. Differences were significant.

CONCLUSION

• In Group A, the new canine model for firearm fragment wounds was tested and proved to be operable and effective. In Group B, hydronephrosis and hydroureter were effectively prevented in ureters by biodegradable stent placement compared with the non-stented ureters where hydronephrosis and hydroureter occurred. The renal concentration capacity was effectively protected and the half-time of kidney washout was shortened.

Operative management of wartime genitourinary injuries at Balad Air Force Theater Hospital, 2005 to 2008

PURPOSE

We detail the 3-year experience of operative combat urology of genitourinary surgeons stationed at Balad Air Force Theater Hospital, Balad, Iraq.

MATERIALS AND METHODS

We performed an institutional review board approved, retrospective review of operative logs of the 9 urologists deployed to Balad Air Force Theater Hospital from June, 1 2005 to June 1, 2008. All operative cases performed by the urologists deployed to this facility were reviewed. Patients were grouped by injury location and operative approach. Analysis included the calculation of relative injury rates by location and the incidence of organ preservation.

RESULTS

During the 36 months reviewed 273 patients underwent a total of 361 operative and 25 endoscopic procedures for 1 or more genitourinary injuries. Of the patients 227 (83.1%) had wounds to the lower genitourinary tract, 39 (14.3%) had wounds to the upper genitourinary tract and 7 (2.6%) had upper and lower genitourinary injuries. Exploration, débridement and repair of soft tissue injury to the external genitalia were the most commonly performed procedures. Of the 88 testicular injuries explored testicular salvage was achieved in 45 (51.1%). Nephrectomy was required in 17 of the 27 operative renal injury cases (63.0%).

CONCLUSIONS

Most genitourinary injuries treated at Balad Air Force Theater Hospital involve the lower genitourinary tract. The high frequency of genital trauma often requires staged reconstructive procedures. Acceptable renal and testicular salvage rates are attainable. This study highlights the diverse array of surgical treatment modalities needed to manage genitourinary trauma during Operation Iraqi Freedom.

The incidence, management, and outcome of penetrating bladder injuries in civilians resultant from armed conflict in Baghdad 2005-2006

The purpose of this paper is to review the diagnosis, treatment, and outcomes of penetrating bladder injuries suffered by civilians in the Iraqi war zone. Materials and Methods. All civilian trauma cases received alive at Al-Yarmouk Teaching Hospital from January 2005 to August 2006 were reviewed for the presence of bladder injury. Results. 533 cases of penetrating abdominal trauma were identified, of which 177 (33%) involved the genitourinary (GU) system and 64 (12%) involved the bladder. Most (70%) were young males, and most (55%) had grade IV injuries. Associated injuries occurred in 63/64 (98%) of patients. 3 patients had missed bladder injuries, and all of these had complications related to their missed injury. Bladder-related complications occurred in 11% of cases, and mortality in 13%, all due to extravesical injuries. Conclusions. Penetrating bladder injury among civilians in Baghdad war zone resulted in 64 cases in 18 months. The initial detection rate is very high (98%), and after primary repair, lasting complications are rare. Morbidities from missed injuries were severe hematuria and vesicorectal fistula. However, (3%) of vesicorectal fistulae healed spontaneously with prolonged bladder drainage. Associated injuries are the rule in penetrating bladder injury patients, and must be diligently investigated and treated.

Evaluation and management of renal injuries: consensus statement of the renal trauma subcommittee

OBJECTIVE

To determine the optimal evaluation and management of renal injuries by review of the world's English-language literature on the subject.

METHODS

A consensus conference convened by the World Health Organization and the Societé Internationale d'Urologie met to critically review reports of the diagnosis and treatment of renal trauma. The English-language literature about renal trauma was identified using Medline, and additional cited works not detected in the initial search obtained. Evidence-based recommendations for the diagnosis and management of renal trauma were made with reference to a five-point scale.

RESULTS

There were many Level 3 and 4 citations, few Level 2, and one Level 1 which supported clinical practice patterns. Findings of nearly 200 reviewed citations are summarized.

CONCLUSIONS

Published reports on renal trauma still rely heavily on expert opinion and single-institution retrospective case series. Prospective trials of the most significant issues, when possible, might improve the quality of evidence that dictates the behaviour of practitioners.
