Retrograde intramedullary nail entry point for tibio-talo-calcaneal arthrodesis: a review of anatomical studies.

PURPOSE: Tibio-talo-calcaneal arthrodesis (TTCA) is considered a safe and valuable option for end-stage tibiotalar and subtalar arthritis, and usually is performed with a retrograde intramedullary nail. Although the good results reported, potential complications may be related to retrograde nail entry point. Aim of this systematic review is to analyze in cadaveric studies the risk of iatrogenic injuries related to different entry points and different retrograde intramedullary nail design when performing TTCA. METHODS: According to PRISMA, a systematic review of the literature was performed on PubMed, EMBASE and SCOPUS databases. A subgroup analysis comparing different entry point location (anatomical or fluoroscopic guided) and different nail design (straight vs. valgus curved nails) was performed. RESULTS: Five studies were included, for a total of 40 specimens. Superiority of anatomical landmark-guided entry points was observed. Different nail designs did not seem to influence nor iatrogenic injuries neither hindfoot alignment. CONCLUSION: Retrograde intramedullary nail entry point should be placed in the lateral half of the hindfoot in order to minimize the risk of iatrogenic injuries.

Managing central venous access during a health care crisis.

OBJECTIVE: During the COVID-19 pandemic, central venous access line teams were implemented at many hospitals throughout the world to provide access for critically ill patients. The objective of this study was to describe the structure, practice patterns, and outcomes of these vascular access teams during the COVID-19 pandemic. METHODS: We conducted a cross-sectional, self-reported study of central venous access line teams in hospitals afflicted with the COVID-19 pandemic. To participate in the study, hospitals were required to meet one of the following criteria: development of a formal plan for a central venous access line team during the pandemic; implementation of a central venous access line team during the pandemic; placement of central venous access by a designated practice group during the pandemic as part of routine clinical practice; or management of an iatrogenic complication related to central venous access in a patient with COVID-19. RESULTS: Participants from 60 hospitals in 13 countries contributed data to the study. Central venous line teams were most commonly composed of vascular surgery and general surgery attending physicians and trainees. Twenty sites had 2657 lines placed by their central venous access line team or designated practice group. During that time, there were 11 (0.4%) iatrogenic complications associated with central venous access procedures performed by the line team or group at those 20 sites. Triple lumen catheters, Cordis (Santa Clara, Calif) catheters, and nontunneled hemodialysis catheters were the most common types of central venous lines placed by the teams. Eight (14%) sites reported experience in placing central venous lines in prone, ventilated patients with COVID-19. A dedicated line cart was used by 35 (59%) of the hospitals. Less than 50% (24 [41%]) of the participating sites reported managing thrombosed central lines in COVID-19 patients. Twenty-three of the sites managed 48 iatrogenic complications in patients with COVID-19 (including complications caused by providers outside of the line team or designated practice group). CONCLUSIONS: Implementation of a dedicated central venous access line team during a pandemic or other health care crisis is a way by which physicians trained in central venous access can contribute their expertise to a stressed health care system. A line team composed of physicians with vascular skill sets provides relief to resource-constrained intensive care unit, ward, and emergency medicine teams with a low rate of iatrogenic complications relative to historical reports. We recommend that a plan for central venous access line team implementation be in place for future health care crises.

Overcoming the Axillary Nerve Blind Spot Through the Deltopectoral and Axillary Approaches: A Cadaveric Study.

PURPOSE: The aim of this study was to evaluate the feasibility of exploring the axillary nerve (AN) at the 6 o'clock position (blind spot) using the deltopectoral approach, with the interval lateral to the conjoint tendon (CJT) or combined with the axillary approach. METHODS: Four ANs were dissected combining the deltopectoral approach-medial to the CJ (A), the deltopectoral approach-lateral to the CJT (B) and the axillary approach (C) in 3 sequences: A-B-C, B-A-C, and C-B-A. After the first approach was completed, the proximal and distal margins were marked. Additional exposure with the second and third approaches and the 6 o'clock position were also marked. Then, the AN was excised and the amount of exposed nerve with the 3 approaches was measured. RESULTS: The deltopectoral approach-medial to the conjoint tendon did not allow exposure of the AN at the 6 o'clock position. Six o'clock position exposure was accomplished using the lateral interval of the deltopectoral and the axillary approaches. A deltopectoral approach lateral to the CJT allowed exploration of the AN at the blind spot, but not the terminal branches. The axillary approach was able to expose the AN at the 6 o'clock position, the terminal branches, but not the nerve-muscle junction. Combining the 3 approaches exposed 81% to 94% of the total length of the AN. CONCLUSIONS: The deltopectoral approach allowed visualization of the AN at the 6 o'clock position when explored lateral to the CJT. The axillary approach allowed visualization of the terminal branches of the AN and the 6 o'clock position of the glenoid. CLINICAL RELEVANCE: The deltopectoral approach lateral to the conjoint tendon allows the surgeon to assess continuity of the AN at the 6-o'clock position and to perform a neurolysis. If nerve repair, nerve grafting, or nerve transfer is attempted, a combination of the 3 approaches could be used.

Liver transplantation as a lifesaving procedure for posthepatectomy liver failure and iatrogenic liver injuries.

BACKGROUND: Iatrogenic injuries to vital structures of the liver and posthepatectomy liver failure are associated with high mortality. The current donor situation in Norway allows liver transplantation of patients beyond conventional criteria. METHODS: From 1984 to 2017, a total of 1510 liver transplantations were performed. In this retrospective study, we report the results of 13 patients undergoing liver transplantation due to iatrogenic injuries to the liver vasculature or posthepatectomy liver failure. RESULTS: Twelve men and one woman with a median age of 55 years (range 22-69) were included. Seven patients underwent radical surgery for cancer prior to transplantation. The median follow-up time was 70.5 months (range 2.2-177). Three of the patients with malignant disease did not experience disease recurrence, whereas four patients had cancer recurrence and died 7, 24, 45, and 78 months after transplantation. Five of six patients with non-malignant disease fully recovered, but one patient died after 9 months due to infectious complications. CONCLUSIONS: Liver transplantation for liver failure due to portal vein and hepatic artery injury in patients with non-malignant disease seems justified. However, it may be questioned whether patients with malignant disease beyond established criteria should be offered liver transplantation.

Cardiothoracic injuries after CardioPump CPR: a report of two cases and review of the literature.

Although many clinical trials have demonstrated its efficacy during active compression-decompression cardiopulmonary resuscitation (ACD-CPR), the Ambu® CardioPump seems likely to cause severe and sometimes lethal injuries. In this paper, we report two cases observed at the Institute of Legal Medicine of Nancy, France. A 67-year-old man collapsed in the street, in the presence of witnesses, and without any sign of trauma. The autopsy revealed a flail chest, a wound of the left ventricle, a rupture of the right ventricle, and a wrenching of the inferior vena cava. A 71-year-old woman was found in her apartment during an accidental fire. The autopsy revealed a sternal fracture, many rib fractures, and a perforation of the superior vena cava, the pericardium, and the heart. Despite articles focusing on complications of the use of the CardioPump in the late 1990s, this technique is still used in practice. These two cases emphasize that iatrogenic injuries must be taken into account in the CardioPump benefit/risk balance and the relevance of its daily use.

[Relevant incidental findings and iatrogenic injuries : A retrospective analysis of 1165 resuscitation room patients]. / Relevante Zufallsbefunde und iatrogene Verletzungen : Eine retrospektive Analyse von 1165 Schockraumpatienten.

BACKGROUND: Whole-body computed tomography (CT) is increasingly being used as the diagnostic modality of choice in patients admitted to the resuscitation room. Beyond findings related to the suspected diagnosis it often additionally reveals incidental findings. The aim of this investigation was the evaluation of these findings in patients admitted via the emergency room after suffering potential major trauma or life-threatening medical conditions. Furthermore, the number of iatrogenic injuries as well as misplaced catheters and endotracheal tubes was investigated. METHODS: All patients admitted from 1 February 2012 to 31 January 2014 via the resuscitation area of the Mannheim University Medical Center, a tertiary care hospital and level 1 trauma center, were included in this study if they had undergone a whole-body CT scan at admission. Data from 1362 patients were collected retrospectively and 197 patients were excluded because of missing data so that the final cohort consisted of 1165 patients (1038 trauma and 127 internal neurological patients). Reports from the whole-body CT scans were screened for incidental findings. These findings were then classified as either clinically relevant or not. Furthermore, the reports were checked for iatrogenic injuries as well as misplaced catheters and endotracheal tubes. RESULTS: A total of 465 incidental findings were reported in 293 patients (25.1%) of the final cohort. In the synopsis of the radiological and clinical findings, 72 were rated as clinically relevant. In one patient two relevant incidental findings were reported and one patient presented with three incidental findings. In total, relevant incidental findings could be detected in 5.8% of the study patients (68/1165). In the discharge letters and/or the radiological report 16.2% of the incidental findings rated as clinically relevant were reported to be previously known, 66.2% were reported to be unknown and 17.6% could not be unequivocally classified as known or unknown due to missing references in the discharge letters. The group of internal neurological patients were clearly older than the trauma patients (61.6 years vs. 45.5 years). The rate of relevant incidental findings in the internal neurological group was more than twice as high as in the trauma group (11.0% vs. 5.2%); however, in the relatively young trauma group 1 in 20 patients showed an incidental finding classified as clinically relevant. In 43 (3.7%) patients a total of 46 iatrogenic injuries or misplaced catheters were reported. The most common finding was a too deeply placed endotracheal tube and five transurethral catheters placed in the emergency room were found to be blocked within the urethra. CONCLUSION: In addition to the main diagnosis, clinically relevant incidental findings were reported in nearly 25% of whole-body CT scans of patients admitted to the resuscitation room. Approximately 6% of patients had incidental findings rated as clinically relevant. In the internal neurological group of patients the rate of incidental findings was doubled compared to the trauma group; however, the latter were significantly younger. Whole-body CT was also useful for diagnosing iatrogenic injuries and misplaced catheters in approximately 4% of the study patients.

Multi-modality imaging of the leaking ureter: why does detection of traumatic and iatrogenic ureteral injuries remain a challenge?

Ureteral injuries are uncommon in trauma patients, accounting for fewer than 1% of all injuries to the urinary tract. These uncommon, yet problematic, injuries can often be overlooked in the standard search pattern on abdominal and pelvic multi-detector CT (MDCT) images, as radiologists focus on more immediate life-threatening injuries. However, early diagnosis and management are vital to reduce potential morbidity. If there is a high clinical index of suspicion for ureteral injuries with penetrating or blunt trauma, or if there is suspected iatrogenic ureteral injury, delayed-phase/urographic-phase MDCT images are essential for confirming the diagnosis. Moreover, making the distinction between partial and complete ureteral transection is critical, as it will guide management. The aim of this pictorial review is to overview the key imaging findings in blunt and penetrating traumatic and iatrogenic injuries of the ureter, as well as to discuss the advantages and disadvantages of different imaging modalities for accurately and rapidly establishing or excluding the diagnosis of ureteral injuries, with an emphasis on MDCT. The potential causes of missed ureteral injuries will also be discussed.

Interventional radiology in iatrogenic ureteral leaks: case series and literature review.

Iatrogenic ureteral injuries are a dramatic complication in medical practice. Nowadays there are no universal guidelines for their management. The aim of our study was to evaluate the feasibility of the percutaneous treatment in restoring ureteral integrity in 19 patients that came to our attention. In each case retrograde stenting failed and patients were candidates for re-surgery. Our strategy consists of two phases. The first step is the nephrostomy that allows an external urinary diversion putting dry the damaged ureteral segment. The second step is the anterograde ureteral double-J stenting that keeps near the two stumps promoting the healing of the injured tract. In complete sections, when both retrograde and anterograde stenting singularly failed, we performed a rendez-vous technique with a combined radiological trans-nephrostomic access and urological cystoscopic approach to realign and catheterize the ureteral stumps. In patients with Bricker urinary diversion, peri-anastomotic leaks were treated by positioning a multi-hole pig-tail catheter with the inner end in the renal pelvis and the distal portion outgoing from the cutaneous stoma. Subsequent pyelographic controls demonstrated the resolution of the ureteral leak in all patients and none required a surgical re-intervention. Nephrostomies were removed and ureteral stents were regularly changed. We conclude that interventional uro-radiology may offer a valid conservative option in iatrogenic urinary injuries.

Quality of life, unmet needs, and iatrogenic injuries in rehabilitation of patients with Ehlers-Danlos Syndrome hypermobility type/Joint Hypermobility Syndrome.

Ehlers-Danlos Syndrome, hypermobility type (EDS-HT) and the joint hypermobility syndrome (JHS) are connective tissue disorders that form an overlapping clinical syndrome and are associated with frequent medical visits and substantial morbidity. EDS-HT/JHS-associated pain correlates with poor quality of life. While physical therapy is the recommended treatment for EDS-HT/JHS, little is known about therapy-related patient experiences and iatrogenic injuries. We studied 38 adult EDS-HT/JHS patients, eliciting health-related quality of life (HRQoL) from 28 patients through the RAND SF-36 questionnaire. We also explored physical therapy experiences through focus groups with 13 patients. Our patients displayed poor HRQoL, with 71% reporting worse health over the past year. SF-36 scores were significantly lower than the scores of the average American population (P < 0.001 for 8 of 10 categories assessed), but were comparable to EDS-HT/JHS populations in Belgium, the Netherlands, Sweden, and Italy. Focus groups identified factors associated with: negative past physical therapy experiences, iatrogenic joint injuries, positive treatment experiences, and unmet rehabilitation needs. This group of EDS-HT/JHS patients has significant decrements in HRQoL and many unmet treatment needs, as well as a risk for iatrogenic injuries. We identify several approaches to help meet patients' needs and improve joint rehabilitation in patients with EDS-HT/JHS. © 2016 Wiley Periodicals, Inc.

Spectrum of Multidetector Computed Tomography Imaging Findings in Iatrogenic Abdominopelvic Injuries: A Comprehensive Pictorial Review.

Iatrogenic injuries are unavoidable complications of surgeries and minimally invasive procedures. They are generally classified into vascular and nonvascular injuries and based on the time of injury into early and late injuries. Iatrogenic injuries, particularly vascular injuries, increase the mortality and morbidity, with prolongation of hospital-stay. Multidetector computed tomography (MDCT) is a highly sensitive, and often the first imaging modality in suspected iatrogenic injuries. This pictorial review elucidates the imaging considerations and appearances of iatrogenic injuries of the abdominopelvic organs on MDCT.

Analysis of mastoid portion of facial nerve course in temporal bone using computed tomography.

<b>Introduction:</b> The facial nerve (FN) follows a complex route in the temporal bone. Successful temporal bone surgery requires knowledge of its course which can be achieved using imaging methods such as computed tomography. This investigation aims to analyze the FN course in its mastoid portion and second genu and the frequency of its atypical course.</br></br> <b>Material and methods:</b> This is a retrospective study that enrolled 104 CT scans of temporal bones of patients followed up in the outpatient clinic of the Otorhinolaryngology Department of Dentistry Faculty of the Medical University of Warsaw between 2020 and 2022. FN courses were classified as straight, bulging, or letter "S"-like. Other parameters estimated: </br> • position of the second genu according to the prominence of the lateral semicircular canal (classified as lateral, medial, or middle) and its distance from a line adjacent to the lateral semicircular canal was measured;</br> • the distance between the short process of the incus and the outermost point of the second genu;</br> • the course of the mastoid portion of FN and the location of SG in comparison to the tympanic portion of n. VII. The course was later classified as lateral, medial, or middle.</br></br> <b>Results:</b> Among the 104 assessed temporal bones, the course of the mastoid portion of FN was classified as bulging in 47 cases (45.2%). Straight and letter "S"-like courses were present in 41 (39.4%) and 16 (15.4%) cases, respectively. Deviation of the second genu according to the prominence of the lateral semicircular canal was medial in 86 cases (82.7%), and middle in 4 cases (3.8%). In the rest, second genu was paramedian to the prominence of the later circular canal. The mean distance between the short process of the incus and the outermost point of SG was 4.9 mm (0.73 mm). The mastoid portion was located laterally, medially, and in the middle of the tympanic portion plane in, respectively, 4.8%, 83.7%, and 11.5%. The second genu was located laterally, medially, and in the middle of the tympanic portion plane in 1.9%, 73.1%, and 25%, respectively. In conclusion, seven temporal bones (6.7%) of five patients presented with a lateral displacement of FN in relation to the established anatomical landmarks.</br></br> <b>Conclusions:</b> Although the atypical course of FN, including the lateral displacement of the mastoid portion, is rare, screening for it is crucial before surgical exploration.

Iatrogenic Injuries in Manual and Mechanical Cardiopulmonary Resuscitation.

PURPOSE: Mechanical chest compression has been shown to be equivalent to manual chest compression in providing survival benefits to patients experiencing cardiac arrest. There has been a growing need for a contemporary review of iatrogenic injuries caused by mechanical in comparison with manual chest compression. Our study aims to analyze the studies that document significant life-threatening iatrogenic injuries caused by mechanical and manual chest compression. METHODS: A systematic review of PubMed and Embase was performed according to Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. All studies published after January 1st, 2000 were reviewed using inclusion/exclusion criteria and completed by May 2020. A total of 7202 patients enrolled in 15 studies were included in our meta-analysis. RESULTS: Significant life-threatening iatrogenic injuries had higher odds of occurring when mechanical chest compression was used compared to manual chest compression, especially for hemothorax and liver lacerations. Mechanical chest compression involves consistently deeper compression depths compared to manual chest compression, potentially resulting in more injuries. In the mechanical chest compression cohort, chest wall fractures had the highest incidence rate (55.7%), followed by sternal fracture (28.3%), lung injuries (3.7%), liver (1.0%), and diaphragm (.2%) lacerations. CONCLUSIONS: Mechanical chest compression was associated with more iatrogenic injuries as compared to manual chest compression. Further research is needed to define the appropriate application of mechanical in comparison with manual chest compression in different scenarios. Levels of provider training, different mechanical chest compression device types, patient demographics, and compression duration/depth may all play roles in influencing outcomes.

Heterotopic Kidney Autotransplantation for Recurrent Iatrogenic Distal Ureteral Injury: A Case Report.

Iatrogenic ureteral injuries are a significant complication during pelvic surgery, requiring a multidisciplinary approach for optimal repair. When a ureteral injury is suspected postoperatively, abdominal imaging is essential to determine the type of injury and thus the timing and method of reconstruction. That can be performed either by a CT pyelogram or by an ureterography-cystography with or without ureter stenting. Although technological advancements and minimally invasive surgery have been gaining ground over open complex surgeries, renal autotransplantation is a well-established technique of proximal ureter repair and should be highly considered when dealing with a severe injury. We hereby report the case of a patient with a recurrent ureter injury and multiple laparotomies treated with autotransplantation, without any major morbidities or change in their quality of life. In every case, a personalized approach for each patient and consultation with experienced transplant experts (surgeons, urologists, and nephrologists) is advised.

Accidental portal vein catheterization during pleural drainage catheter insertion: a case report.

BACKGROUND: Iatrogenic portal vein (PV) injuries following pleural drainage catheter (PDC) insertion are rare but life-threatening. This case report emphasizes the importance of prompt recognition and effective interventional radiology (IR) management. CASE PRESENTATION: A 38-year-old Asian male, admitted for a non-ST-segment elevation myocardial infarction, suffered a critical PV injury during PDC insertion, leading to rapid clinical deterioration. The IR team conducted a portogram, retrieved the catheter, and successfully executed an embolization procedure. The patient's recovery, confirmed through imaging and improving liver function tests, enabled discharge with follow-up instructions. CONCLUSIONS: This case highlights the clinical significance of promptly recognizing and effectively managing iatrogenic PV injuries during PDC insertion, with the pivotal role of IR. Collaboration between IR and surgical teams is crucial for optimizing patient outcomes.

Facial nerve: A review of the anatomical, surgical landmarks and its iatrogenic injuries.

Facial nerve iatrogenic injuries are serious and can negatively affect the quality of life of the patients. Due to the properties of the nerve, the complications are devastating involving the aesthetic appearance and the function of the face. Moreover, the multiple branches of the nerve increase the risk of an iatrogenic injury making the detailed knowledge of the anatomical correlations around them critical. In this review, a meticulous analysis was performed including the surgical procedures posing the greater risk of an iatrogenic injury as well as the full description of all the reported anatomical landmarks involving the extracranial course of the facial nerve.

CT Analysis of a Potential Safe Zone for Placing External Fixator Pins in the Humerus.

BACKGROUND: Iatrogenic radial nerve injures are a common complication during the placement of external fixator pins at the lateral aspect of the humeral shaft. This study uses a three-dimensional measurement technique to locate a safe entry point for humeral pins when externally fixating the elbow. Methods: We fixed a guide wire to the radial nerve by a suture string, and used computed tomography (CT) to scan the upper limbs of cadaver specimens. Then, we measured the deviation angles of the radial nerve on the CT scans, and the distance from the radial nerve to the "elbow rotation center" (ERC). Result: The average distance from the radial nerve to the ERC was 87.3 ± 8.5 mm (range: 68-100 mm), 58.3 ± 11.3 mm (range: 32.12-82.84 mm), 106.3 ± 5.8 mm (range: 86.93-115.08 mm), and 113.9 ± 4.8 mm (range: 97.93-120.22 mm) at radial nerve deviation angles of 0°, -30°, 30°, and 45°, respectively. The average radial nerve deviation angle was -37.7° ± 7.7° and 123.9° ± 19.9° at 50 and 150 mm, respectively. Relative to 0°, the distance between the radial nerve and the ERC at radial nerve deviation angles of -30°, 30°, and 45° showed a significant difference (t = 18.20, p < 0.05; Z = 6.07, p < 0.001; Z = 6.40, p < 0.001, respectively). Conclusions: Pins inserted into the proximal humerus should be about 150 mm from the ERC with a radial nerve deviation angle of 30° anteriorly, and 50 mm from the ERC with a deviation angle of 30°-45° posteriorly.

Bile duct injuries after cholecystectomy, analysis of constant risk.

BACKGROUNDS/AIMS: The bile duct injuries are the most severe complications that occur after the surgical manipulation of the bile duct. The hepaticojejunostomy remained as the best treatment. Several factors identified that affect the result. This study aimed to analyze and identify risk factors that affected the evolution of these patients. METHODS: A retrospective, observational study was conducted from February 1998 to June 2017. We included all patients with bile duct injuries who required surgical treatment. RESULTS: We found 79 patients. The majority had a Bismuth type III in 35.4% (n=28). The morbidity of the Hepaticojejunostomy was 19% (n=15). In short-term follow-up, the main complications were cholangitis 11.4% (n=9) and bile leak 10% (n=8). In the long-term follow-up, in 2.5% (n=2) stricture was presented. On the comparison between postoperative and preoperative parameters, biliary peritonitis after a cholecystectomy (p=0.02) was an independent predictor of postoperative morbidity (p<0.05). CONCLUSIONS: In the treatment of bile duct injuries, different factors affect their outcomes. Our results show that infectious complications continue to affect the results of the treatment of bile duct lesions.

Managing Mid and Lower Ureteral Benign Strictures: The Laparoscopic Way.

OBJECTIVE: The aim of this study is to assess etiopathogenesis of ureteral mid/lower benign strictures and outcomes of various methods of laparoscopic reconstruction and repair. MATERIALS AND METHODS: We retrospectively reviewed the data of patients who underwent laparoscopic repair for mid and lower ureteral benign strictures at our department from January 2013 to February 2016. The demographic, operative, complication, and outcome data were analyzed. RESULTS: Twenty-two patients were treated by various methods of laparoscopic reconstruction in the department of urology for benign ureteral strictures. Ureteroneocystostomy was done by psoas hitch in 15 and Boari flap in 2. Ureteral tapering, followed by ureteral reimplantation, was done in 2 and ureteroureterostomy in 3 cases. The most common predisposing factor that leads to ureteral stricture was prior pelvic gynecological surgery. Other causes included endometriosis, tuberculosis, impacted ureteral calculus, and ureteroscopic removal of calculus. Seventeen patients had lower, 3 had mid, and 2 had mid/lower ureteral strictures. Ureteral patency was successfully reestablished in all 22 patients without significant complications during a mean follow-up of 25 months (range 12-48 months). CONCLUSION: Laparoscopic treatment of benign ureteral strictures imparted excellent outcomes without major complications with the advantage of the minimally invasive technique.

Iatrogenic Peripheral Nerve Injuries-Surgical Treatment and Outcome: 10 Years' Experience.

BACKGROUND: Iatrogenic nerve injuries are nerve injuries caused by medical interventions or inflicted accidentally by a treating physician. METHODS: We describe and analyze iatrogenic nerve injuries in a total of 122 consecutive patients who received surgical treatment at our Institution during a period of 10 years, from January 1, 2003, to December 31, 2013. The final outcome evaluation was performed 2 years after surgical treatment. RESULTS: The most common causes of iatrogenic nerve injuries among patients in the study were the operations of bone fractures (23.9%), lymph node biopsy (19.7%), and carpal tunnel release (18%). The most affected nerves were median nerve (21.3%), accessory nerve (18%), radial nerve (15.6%), and peroneal nerve (11.5%). In 74 (60.7%) patients, surgery was performed 6 months after the injury, and in 48 (39.3%) surgery was performed within 6 months after the injury. In 80 (65.6%) patients, we found lesion in discontinuity, and in 42 (34.4%) patients lesion in continuity. The distribution of surgical procedures performed was as follows: autotransplantation (51.6%), neurolysis (23.8%), nerve transfer (13.9%), direct suture (8.2%), and resection of neuroma (2.5%). In total, we achieved satisfactory recovery in 91 (74.6%), whereas the result was dissatisfactory in 31 (25.4%) patients. CONCLUSIONS: Patients with iatrogenic nerve injuries should be examined as soon as possible by experts with experience in traumatic nerve injuries, so that the correct diagnosis can be reached and the appropriate therapy planned. The timing of reconstructive surgery and the technique used are the crucial factors for functional recovery.

Foley Follies: Emphysematous Pyelitis from Instrumentation in Obstructive Uropathy.

Emphysematous pyelitis (EP) is a subclass of a life-threatening necrotizing infection of the urinary system called emphysematous pyelonephritis (EPN). We report a case of an 81-year-old man with emphysematous pyelitis, which occurred after urinary tract instrumentation and resolved with conservative medical management. This case highlights the potential complications of urinary tract manipulation and the importance of a prompt diagnosis.
