Abstract
Background Procedural planning for transcatheter aortic valve replacement (TAVR) is routinely performed using contrast computed tomography (CT) in patients with severe aortic stenosis (AS). Despite its potential, little investigation has been done into the possibility of aortic valve calcification (AVC) scoring in contrast-enhanced CT. Contrast CT has superior spatial and contrast resolution compared to the non-contrast Agatston score protocol, which would allow for development of better pattern and distribution descriptors of calcific lesions in the aortic valve (AV). Methods We developed a new false positive rate (FPR) based method that can quantify leaflet calcification based on shape overlap metrics. We also introduce a novel regional scheme for quantifying the shape and structure of calcification using topographic maps. The study was designed to: (I) determine the feasibility of using a novel method based on FPR to detect AVC using contrast-enhanced CT images by assessing the volume scores measured using FPR versus non-contrast methods and alternative contrast methods for volume scoring based on fixed or dynamic HU thresholds. (II) Develop a new scheme for assessing calcific geometry and structure and evaluate patterns of calcification in the varied presentation of AS. Results Our results show a very strong correlation with non-contrast volume (r=0.919, P<0.001; n=178) and Agatston scores (r=0.913, P<0.001; n=178) that were evaluated using a standard calcium scoring technique. Finally, we analyzed the differences and similarities in the patterns of calcific deposition with respect to sex and degree of severity. Conclusions The FPR method demonstrates the best overall agreement with non-contrast scores across both low and high ends of calcific density compared to luminal attenuation methods. In addition, we showed that leaflet calcific deposition follows distinctive patterns across the belly of the leaflet, with the rate of calcific progression peaking at the non-coronary cusp (NCC) leaflet and lowest for the right-coronary cusp. Females experience significantly lower calcific deposition compared to males despite showing similar patterns and symptoms. Our findings suggest that precise regional assessment of calcific progression could be an important tool for monitoring AS development as well as predicting peri-procedural complications in TAVR.

Abstract
BACKGROUND Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks. METHODS The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned. RESULTS A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P < 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31). CONCLUSION Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov).

Abstract
Breast cancer retains its position as the most prevalent form of malignancy among females on a global scale. The careful selection of appropriate treatment for each patient holds paramount importance in effectively managing breast cancer. Neoadjuvant chemotherapy (NACT) plays a pivotal role in the comprehensive treatment of this disease. Administering chemotherapy before surgery, NACT becomes a powerful tool in reducing tumor size, potentially enabling fewer invasive surgical procedures and even rendering initially inoperable tumors amenable to surgery. However, a significant challenge lies in the varying responses exhibited by different patients towards NACT. To address this challenge, researchers have focused on developing prediction models that can identify those who would benefit from NACT and those who would not. Such models have the potential to reduce treatment costs and contribute to a more efficient and accurate management of breast cancer. Therefore, this review has two objectives: first, to identify the most effective radiomic markers correlated with NACT response, and second, to explore whether integrating radiomic markers extracted from radiological images with pathological markers can enhance the predictive accuracy of NACT response. This review will delve into addressing these research questions and also shed light on the emerging research direction of leveraging artificial intelligence techniques for predicting NACT response, thereby shaping the future landscape of breast cancer treatment.

Abstract
Background Despite the demonstrated benefits of transcatheter aortic valve replacement (TAVR), subclinical leaflet thrombosis and hypoattenuated leaflet thickening are commonly seen as initial indications of decreased valve durability and augmented risk of transient ischemic attack. Methods We developed a multiscale patient-specific computational framework to quantify metrics of global circulatory function, metrics of global cardiac function, and local cardiac fluid dynamics of the aortic root and coronary arteries. Results Based on our findings, TAVR might be associated with a high risk of blood stagnation in the neo-sinus region due to the lack of sufficient blood flow washout during the diastole phase (e.g., maximum blood stasis volume increased by 13, 8, and 2.7 fold in the left coronary cusp, right coronary cusp, and noncoronary cusp, respectively [N = 26]). Moreover, in some patients, TAVR might not be associated with left ventricle load relief (e.g., left ventricle load reduced only by 1.2 % [N = 26]) and diastolic coronary flow improvement (e.g., maximum coronary flow reduced by 4.94%, 15.05%, and 23.59% in the left anterior descending, left circumflex coronary artery, and right coronary artery, respectively, [N = 26]). Conclusions The transvalvular pressure gradient amelioration after TAVR might not translate into adequate sinus blood washout, optimal coronary flow, and reduced cardiac stress. Noninvasive personalized computational modeling can facilitate the determination of the most effective revascularization strategy pre-TAVR and monitor leaflet thrombosis and coronary plaque progression post-TAVR.

Abstract
BACKGROUND Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. METHODS This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low-middle-income countries. RESULTS In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of 'single-use' consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low-middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. CONCLUSION This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high- and low-middle-income countries.

Abstract
Background Despite the proven benefits of transcatheter aortic valve replacement (TAVR) and its recent expansion toward the whole risk spectrum, coronary artery disease is present in more than half of the candidates for TAVR. Many previous studies do not focus on the longer-term impact of TAVR on coronary arteries, and hemodynamic changes to the circulatory system in response to the anatomical changes caused by TAVR are not fully understood. Methods and Results We developed a multiscale patient-specific computational framework to examine the effect of TAVR on coronary and cardiac hemodynamics noninvasively. Based on our findings, TAVR might have an adverse impact on coronary hemodynamics due to the lack of sufficient coronary blood flow during diastole phase (eg, maximum coronary flow rate reduced by 8.98%, 16.83%, and 22.73% in the left anterior descending, left circumflex coronary artery, and right coronary artery, respectively [N=31]). Moreover, TAVR may increase the left ventricle workload (eg, left ventricle workload increased by 2.52% [N=31]) and decrease the coronary wall shear stress (eg, maximum time averaged wall shear stress reduced by 9.47%, 7.75%, 6.94%, 8.07%, and 6.28% for bifurcation, left main coronary artery, left anterior descending, left circumflex coronary artery, and right coronary artery branches, respectively). Conclusions The transvalvular pressure gradient relief after TAVR might not result in coronary flow improvement and reduced cardiac load. Optimal revascularization strategy pre-TAVR and progression of coronary artery disease after TAVR could be determined by noninvasive personalized computational modeling.

Abstract
Given the associated risks with transcatheter aortic valve replacement (TAVR), it is crucial to determine how the implant will affect the valve dynamics and cardiac function, and if TAVR will improve or worsen the outcome of the patient. Effective treatment strategies, indeed, rely heavily on the complete understanding of the valve dynamics. We developed an innovative Doppler-exclusive non-invasive computational framework that can function as a diagnostic tool to assess valve dynamics in patients with aortic stenosis in both pre- and post-TAVR status. Clinical Doppler pressure was reduced by TAVR (52.2 ± 20.4 vs. 17.3 ± 13.8 [mmHg], p < 0.001), but it was not always accompanied by improvements in valve dynamics and left ventricle (LV) hemodynamics metrics. TAVR had no effect on LV workload in 4 patients, and LV workload post-TAVR significantly rose in 4 other patients. Despite the group level improvements in maximum LV pressure (166.4 ± 32.2 vs 131.4 ± 16.9 [mmHg], p < 0.05), only 5 of the 12 patients (41%) had a decrease in LV pressure. Moreover, TAVR did not always improve valve dynamics. TAVR did not necessarily result in a decrease (in 9 out of 12 patients investigated in this study) in major principal stress on the aortic valve leaflets which is one of the main contributors in valve degeneration and, consequently, failure of heart valves. Diastolic stresses increased significantly post-TAVR (34%, 109% and 81%, p < 0.001) for each left, right and non-coronary leaflets respectively. Moreover, we quantified the stiffness and material properties of aortic valve leaflets which correspond with the reduced calcified region average stiffness among leaflets (66%, 74% and 62%; p < 0.001; N = 12). Valve dynamics post-intervention should be quantified and monitored to ensure the improvement of patient conditions and prevent any further complications. Improper evaluation of biomechanical valve features pre-intervention as well as post-intervention may result in harmful effects post-TAVR in patients including paravalvular leaks, valve degeneration, failure of TAVR and heart failure.

Abstract
BACKGROUND Breast cancer is a common women's disease. Usually, oestrogen is blamed in the aetiology and correlated with the prognosis; however, androgens are recently raising concern about its role in the breast cancer treatment and prognosis. METHODS In this study we retrieved archival paraffin blocks of breast cancer patients and stained it for androgen. Thereafter, we compared clinico-epidemiologic parameters, histopathology, neoadjuvant response and recurrence rate and pattern among patients with and without androgen receptor (AR) expression. RESULTS In total, 119 patients fulfilled enrolment criteria; AR expression were present in 77.3% of the patients. AR expression was associated with less grade III (6.8% versus 36.4%), and less triple negative (6.2% versus 25%), but similar overall recurrence rate (25% versus 22.2%). However, distant recurrence was significantly higher in androgen positive patients (91.3% versus 33.3% of all recurrences). CONCLUSION Androgen expression appears to be common among breast cancer, but with no clear implication in tumour aggressiveness or effect on the rate of recurrence. However, being commonly associated with distant spread may have an impact on survival of the patients.

Abstract
BACKGROUND Multifocal (MFBC)/multicentric (MCBC) breast cancer is being more recognized due to the improved imaging modalities and the greater orientation with this form of breast cancer, however, optimal surgical treatment, still poses a challenge. The standard surgical treatment is mastectomy, however, breast-conserving surgeries (BCS) may be appropriate in certain situations. METHODS A total of 464 cases of MF/MCBC out of 4798 cases of breast cancer were retrospectively analyzed from the database of the Oncology Center, Mansoura University (OCMU), between January 2008 and December 2019. RESULTS Radiologic involvement of multiple quadrants was reported in 27.9% by ultrasonography, 19% by mammography, and 59.1% by magnetic resonance imaging. BCS was performed in 32 cases (6.9%) while 432 cases underwent a mastectomy. Postoperative pathology revealed infiltration of other quadrants grossly in 23.5%, and under the microscope in 63.6% of the examined cases. Mean disease-free and overall survival were 95.5 and 164.6 months, respectively. When compared with MFBC, MCBC showed higher pathologic tumor size (p < 0.001), higher stages (p < 0.001), higher recurrence rates (p = 0.006), and lower DFS (P = 0.009) but with similar OS (P = 0.8). CONCLUSION Mastectomy is still the primary treatment option for MCBC with higher recurrence rates compared with MFBC. However, BCS for properly selected MFBC is considered oncologically safe, following the same rules of breast conservation for unifocal disease.

Abstract
BACKGROUND Colorectal cancer management may require an ostomy formation; however, a stoma may negatively impact health-related quality of life (HRQoL). This study aimed to compare generic and stoma-specific HRQoL in patients with a permanent colostomy after rectal cancer across different countries. METHOD A cross-sectional cohorts of patients with a colostomy after rectal cancer in Denmark, Sweden, Spain, the Netherlands, China, Portugal, Australia, Lithuania, Egypt, and Israel were invited to complete questionnaires regarding demographic and socioeconomic factors along with the Colostomy Impact (CI) score, European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ-C30) and five anchor questions assessing colostomy impact on HRQoL. The background characteristics of the cohorts from each country were compared and generic HRQoL was measured with the EORTC QLQ-C30 presented for the total cohort. Results were compared with normative data of reference European populations. The predictors of reduced HRQoL were investigated by multivariable logistic regression, including demographic and socioeconomic factors and stoma-related problems. RESULTS A total of 2557 patients were included. Response rates varied between 51-93 per cent. Mean time from stoma creation was 2.5-6.2 (range 1.1-39.2) years. A total of 25.8 per cent of patients reported that their colostomy impairs their HRQoL 'some'/'a lot'. This group had significantly unfavourable scores across all EORTC subscales compared with patients reporting 'no'/'a little' impaired HRQoL. Generic HRQoL differed significantly between countries, but resembled the HRQoL of reference populations. Multivariable logistic regression showed that stoma dysfunction, including high CI score (OR 3.32), financial burden from the stoma (OR 1.98), unemployment (OR 2.74), being single/widowed (OR 1.35) and young age (OR 1.01 per year) predicted reduced stoma-related HRQoL. CONCLUSION Overall HRQoL is preserved in patients with a colostomy after rectal cancer, but a quarter of the patients interviewed reported impaired HRQoL. Differences among several countries were reported and socioeconomic factors correlated with reduced quality of life.

Abstract
BackgroundIn this retrospective study, we discuss our experience as a large tertiary referral center in Egypt in the management and follow-up of borderline tumorsPatients and methodsThis is a retrospective cohort study where all patients diagnosed with a borderline ovarian tumor at Oncology Center Mansoura University from November 2014 to June 2020 were included. Demographics, preoperative, operative, postoperative, pathologic, and oncologic follow-up data were retrieved from a prospectively maintained electronic database. The included patients were followed until April 2022.ResultsWe included 27 patients with borderline ovarian tumors. The mean age of the study patients was 47.67 ± 16.39 years. The median CA 125 was 33 (6–304 U/ml). Frozen section examination was utilized in 13 patients (48.14%), where a diagnosis of borderline ovarian tumors was revealed in 8 patients. Recurrence was reported in one patient with serous type after approximately 26 months. The most common pathological type in our cohort was the mucinous borderline type reported in 14 patients (51.9%), followed by the serous type reported in 11 patients (40.7%), and the seromucinous type in 1 patient only. Patients with mucinous borderline type were significantly younger (40.083 ± 18.47 vs. 53.73 ± 11.91 years, p = 0.028). Interestingly, Cancer Antigen 125 levels were significantly higher in mucinous than serous and seromucinous types [67(16–304) vs. 20(6–294.6) U/ml, p = 0.027]. On the other hand, the radiological tumor size of serous and seromucinous types was larger than that of the mucinous type [23(19–31) cm vs. 8(5–20) cm, p = 0.001]. Over a median follow-up period of 58.66 (54.16–63.16) months, only one postoperative mortality was reported, while only one recurrence was reported.ConclusionBorderline ovarian tumors still represent a dilemma either in diagnosis or management. A frozen section examination could help to reach a preliminary diagnosis. Total abdominal hysterectomy and bilateral salpingo-oophorectomy are the cornerstone of surgical management; however, fertility-sparing surgery could be a valid option for women desiring fertility.

Abstract
Obesity has long been associated with endometrial cancer. However, there is a paucity of studies addressing the impact of morbid obesity in type II endometrial cancer on oncologic and surgical outcomes. In this study, the author retrospectively compared morbid to non-morbid obese in clinico-epidemiologic, surgical, and oncologic outcomes. Both groups were comparable as regards all clinico-epidemiologic parameters. Vaginal involvement, survival, and recurrence were also comparable between the 2 groups. Para-aortic adenopathy and treatment with preoperative therapy were the only significant predictors of DFS. Surgery is feasible with equivalent complications and oncologic outcomes in morbidly obese patients with type II endometrial cancer.

Abstract
Abstract
Introduction
There are different types of malignant tumors that can affect the thyroid gland where differentiated thyroid carcinomas (papillary and follicular) are the most common representing nearly 90% of cases. Non-epithelial malignancies were also reported to affect the thyroid gland particularly lymphomas and sarcomas that were reported in literature to range from 0.01 to 1.5% of thyroid carcinoma. Herein, we present a case with primary thyroid chondrosarcoma, an extremely rare malignancy of the thyroid gland.
Case presentation
We present a 79-year-old female patient complaining of hard thyroid swelling that was proved to be primary thyroid chondrosarcoma after histopathological assessment.
Conclusion
Chondrosarcoma of the thyroid gland is extremely rare either in the primary or metastatic setting. Although the prognosis is bad, surgery is the main line of treatment after early prompt diagnosis.

Abstract
BACKGROUND Total mesorectal excision (TME) is the gold standard treatment for rectal cancer. Although TME has managed to decrease the rates of local recurrence after rectal cancer resection, local recurrence is still recorded at varying rates. The present study aimed to validate the PREDICT score in the prediction of local recurrence of rectal cancer after TME with curative intent. METHODS This was a retrospective multicenter study on patients with nonmetastatic low or middle rectal cancer who underwent TME. The total PREDICT score was calculated for every patient and related to the onset of local recurrence. According to the final score, patients were allocated to one of three risk groups: low, moderate, and high, and the rates of local recurrence in each group were calculated and compared. RESULTS The present study included 262 patients (50.4% males) with a mean age of 47.1 years. The overall local recurrence rate was 12.6%. 29.4% of patients were in the low-risk group, 63.7% in the moderate-risk group, and 6.9% in the high-risk group. The local recurrence rate was 3.9% (95% confidence interval [CI]: 0.8-10.9) in the low-risk group, 13.2% (95% CI: 8.4-19.3) in the moderate risk group, and 44.4% (95% CI: 21.5-69.2) in the high-risk group (p < 0.0001). The sensitivity of the PREDICT score was 72.7%, the specificity was 88.1%, and the accuracy was 86.3%. CONCLUSIONS The PREDICT score had good diagnostic accuracy in the prediction of local recurrence after TME and a good discriminatory ability in the differentiation between patients at different risks to develop local recurrence.

Abstract
OBJECTIVES In addition to excess mortality due to COVID-19, the pandemic has been characterised by excess mortality due to non-COVID diagnoses and consistent reports of patients delaying seeking medical treatment. This study seeks to compare the outcomes of cardiac surgery during and before the COVID-19 pandemic. DESIGN Our institutional database was interrogated retrospectively to identify all patients undergoing one of three index procedures during the first six months of the pandemic and the corresponding epochs of the previous five years. SETTING A regional cardiothoracic centre. PARTICIPANTS All patients undergoing surgery during weeks #13-37, 2015-2020. MAIN OUTCOME MEASURES Propensity score weighted analysis was employed to compare the incidence of major complications (stroke, renal failure, re-ventilation), 30-day mortality, six month survival and length of hospital stay between the two groups. RESULTS There was no difference in 30-day mortality (HR = 0.76 [95% CI 0.27-2.20], p = 0.6211), 6-month survival (HR = 0.94 [95% CI 0.44-2.01], p = 0.8809) and duration of stay (SHR = 1.00 (95% CI 0.90-1.12), p = 0.959) between the two eras. There were no differences in the incidence of major complications (weighted chi-square test: renal failure: p = 0.923, stroke: p = 0.991, new respiratory failure: p = 0.856). CONCLUSIONS Cardiac surgery is as safe now as in the previous five years. Concerns over the transmission of COVID-19 in hospital are understandable but patients should be encouraged not to delay seeking medical attention. All involved in healthcare and the wider public should be reassured by these findings.

Abstract
Background: Epstein-Barr virus (EBV) has been implicated in the development of breast cancer (BC) since 1995. It is classified into A/B genotypes, C/D subtypes, and F/f variants according to variations in its genome. Aim: To determine the distribution difference of EBV types between BC patients and healthy controls in Egypt and to detect the association between different EBV types and BC characteristics. Methods: Three hundred and sixty-two participants (142 BC patients and 220 controls) were enrolled in this study. All participants were screened for EBV infection by determination of viral-capsid-IgG antibodies in their sera. EBNA-1 gene was detected by PCR in tumor biopsies of seropositive patients and in peripheral blood mononuclear cells of controls. A/B genotyping of EBV was performed by nested-PCR targeting the EBNA-2 gene. C/D subtypes and F/f variants were identified by Restriction fragment length polymorphism at BamHI-I W1/I1 and BamHI-F regions of EBV genome, respectively. Results: Among 362 participants, 300(82.9%) were EBV-seropositive, including 120/142(84.5%) of the BC patients and 180/220(81.8 %) of the controls. EBNA-1 gene was positive in 54(45%) of seropositive BC patients and in 38(21.1%) of seropositive controls. There was a significant association of EBNA-1 gene with breast cancer (OR=3.05, 95%CI=1.84-5.07). Moreover, EBNA-1 gene positivity was significantly associated with the more aggressive tumors. Genotype-A and prototype-F were predominant among patients (90.4%, 100%, respectively) as well as among controls (91.7%, 100%, respectively) with no statistical significant association with BC risk. However, subtype-D was significantly more frequent in patients (95.6%) than in controls (64.7%) and was significantly associated with a higher BC risk as compared to subtype-C (OR=11.7, 95%CI=2.4-57.08). Subtype-D was significantly associated with higher grades tumors (100% among grade III), with progesteron receptor-negative tumors and with HER2-positive tumors (100% for each). The combined genotypes that significantly associated with BC risk were ADF (OR=4.9) and BDF (OR=5.5). Conclusions: Subtype-D of EBV could be the only EBV type implicated in BC development among Egyptian females and associated more with poor prognosis.

Abstract
Purpose Colorectal cancer (CRC) is the third most commonly diagnosed cancer worldwide and the second cause of cancer related mortality. Treatment options for patients with metastatic CRC (mCRC) expanded during the last two decades, with introduction of new chemotherapeutic and targeted agents. Egypt is a lower middle-income country; Egyptian health care system is fragmented with wide diversity in drug availability and reimbursement policies across different health care providing facilities. We report the results of consensus recommendations for treatment of patients with metastatic colorectal cancer developed by Egyptian Foundation of Medical Sciences (EFMS), aiming to harmonize clinical practice through structured expert consensus-based recommendations consistent with the national status. EFMS recommendations could be utilized in other countries with similar economic status. Methods EFMS recommendations were developed using a modified Delphi process, with three rounds of voting till the final recommendations were approved. A non-systematic review of literature was conducted before generating the provisional statements. Content experts were asked to vote on some recommendations in two different resource groups (restricted resources and non-restricted resources). External review board of experts from a low income and lower-middle countries voted on the applicability of EFMS recommendations in their countries. Results The current recommendations highlighted the discrepancy in health care between restricted and non-restricted resources with expected survival loss and quality of life deterioration. Access to targeted agents in first line is very limited in governmental institutions, and no access to agents approved for third line in patients who failed oxaliplatin and irinotecan containing regimens for patients treated in restricted resource settings. Conclusion Management of mCRC in developing countries is a challenge. The currently available resource-stratified guidelines developed by international cancer societies represent a valuable decision-making tool, adaptation to national status in each country based on healthcare system status is required.

Abstract
Cardiovascular disease is a deadly global health crisis that carries a substantial financial burden. Innovative treatment and management of cardiovascular disease straddles medicine, personalized hemodynamic modeling, machine learning, and modern imaging to help improve patient outcomes and reduce the economic impact. Hemodynamic modeling offers a non-invasive method to provide clinicians with new pre- and post- procedural metrics and aid in the selection of treatment options. Medical imaging is an integral part in clinical workflows for understanding and managing cardiac disease and interventions. Coupling machine learning with modeling, and cardiovascular imaging, provides faster modeling, improved data fidelity, and an enhanced understanding and earlier detection of cardiovascular anomalies, leading to the development of patient-specific diagnostic and predictive tools for characterizing and assessing cardiovascular outcomes. Herein, we provide a scoping review of translational hemodynamic modeling, medical imaging, and machine learning and their applications to cardiovascular interventions. We particularly focus on providing an intuitive understanding of each of these approaches and their ability to support decision making during important clinical milestones.

Abstract
Background The aim of this study was to describe the clinical characteristics and outcome of patients with coronavirus disease-2019 (COVID-19) pneumonia admitted to an intensive care unit (ICU) of a tertiary care center in the United Arab Emirates (UAE) and to identify early risk factors for in-hospital mortality in these patients. Methods A total of 371 adult patients (>18 years) admitted to the ICU of Al Ain Hospital between March 16 and July 19, 2020 with SARS-CoV-2 infection confirmed using real-time reverse transcription polymerase chain reaction (rt-PCR) on nasopharyngeal swabs were included. Results The mean patient age was 53 years (standard deviation = 13). Patients were mostly male (n = 314 [84.6%]) and of South Asian origin (n = 231 [62.3%]). Invasive mechanical ventilation was required in 182 (49.1%) patients for a median of 11 days (25–75% interquartile range: 6–17). During the ICU stay, renal replacement therapy was required in 87 (23.5%) and vasopressor therapy in 190 (51.2%) patients. ICU and hospital lengths of stay were 9 (IQ: 5–17) and 18 (IQ: 13–29) days, respectively and ICU and hospital mortality rates were both 20.2%. In a multivariable analysis with in-hospital mortality as the dependent variable, greater Acute Physiology and Chronic Health Evaluation II score on ICU admission, diarrhea prior to hospital admission, greater, admission from hospital ward, and higher lactate dehydrogenase levels and neutrophil:lymphocyte ratio on admission to the ICU were independently associated with higher risk of in-hospital mortality. Conclusion In this cohort of patients admitted to the ICU of a tertiary hospital in the UAE, COVID-19 pneumonia was associated with high morbidity and mortality rates. Identifying patients at high risk of death may help detect future therapeutic targets.

Abstract
BACKGROUND 80% of individuals with cancer will require a surgical procedure, yet little comparative data exist on early outcomes in low-income and middle-income countries (LMICs). We compared postoperative outcomes in breast, colorectal, and gastric cancer surgery in hospitals worldwide, focusing on the effect of disease stage and complications on postoperative mortality. METHODS This was a multicentre, international prospective cohort study of consecutive adult patients undergoing surgery for primary breast, colorectal, or gastric cancer requiring a skin incision done under general or neuraxial anaesthesia. The primary outcome was death or major complication within 30 days of surgery. Multilevel logistic regression determined relationships within three-level nested models of patients within hospitals and countries. Hospital-level infrastructure effects were explored with three-way mediation analyses. This study was registered with ClinicalTrials.gov, NCT03471494. FINDINGS Between April 1, 2018, and Jan 31, 2019, we enrolled 15 958 patients from 428 hospitals in 82 countries (high income 9106 patients, 31 countries; upper-middle income 2721 patients, 23 countries; or lower-middle income 4131 patients, 28 countries). Patients in LMICs presented with more advanced disease compared with patients in high-income countries. 30-day mortality was higher for gastric cancer in low-income or lower-middle-income countries (adjusted odds ratio 3·72, 95% CI 1·70-8·16) and for colorectal cancer in low-income or lower-middle-income countries (4·59, 2·39-8·80) and upper-middle-income countries (2·06, 1·11-3·83). No difference in 30-day mortality was seen in breast cancer. The proportion of patients who died after a major complication was greatest in low-income or lower-middle-income countries (6·15, 3·26-11·59) and upper-middle-income countries (3·89, 2·08-7·29). Postoperative death after complications was partly explained by patient factors (60%) and partly by hospital or country (40%). The absence of consistently available postoperative care facilities was associated with seven to 10 more deaths per 100 major complications in LMICs. Cancer stage alone explained little of the early variation in mortality or postoperative complications. INTERPRETATION Higher levels of mortality after cancer surgery in LMICs was not fully explained by later presentation of disease. The capacity to rescue patients from surgical complications is a tangible opportunity for meaningful intervention. Early death after cancer surgery might be reduced by policies focusing on strengthening perioperative care systems to detect and intervene in common complications.

Abstract
Introduction: Scholarship applicants often receive different advice on what should be included in their Curriculum Vitae (CV). This study aims to investigate what the essential components of a CV being prepared for scholarships are, how to present them, and what their level of impact is. Materials and Methods: The authors sent an online structured questionnaire to 7512 corresponding authors of recent published papers in Scopus; 124 completed questionnaires were returned. Recommended elements for a CV were chosen according to the Delphi consensus technique with a threshold of 50%. Results: This survey revealed that headings, bullet points and careful error checking were essential parts of the layout. For the content of the CV, besides publications, education and training background, research experience and research interest were also necessary. Moreover, almost all respondents ranked publications as the most important qualification of an academic scholarship candidate. Publications also came first as the most impressive factor, followed by awards and honours. The number of publications, quality of journal, impact factor and total citation should be presented in publication section. The importance of publications in getting academic scholarships is significantly emphasized in this recent study. Conclusions: Having research experience and papers in peer review journals, are highly recommended for students seeking academic scholarships.

Abstract
BACKGROUND Colon cancer is a major health problem and is one of the most frequent cancers all over the world. In Egypt, the incidence of colon cancer is relatively low, but its mortality rate is high. Lymphatic spread of colon cancer is one of the most important factors affecting the prognosis of patients. Recently, the lymph node ratio (LNR) has been evaluated as a prognostic parameter for survival. This study aimed at evaluation of nodal status of resected specimens and LNR, as well as its impact on the disease-free survival (DFS) and overall survival (OS) after curative resection of right colon cancer. METHODS The institutional registry of the Oncology Center Mansoura University (OCMU) was revised for node-positive right colon cancer cases that were operated in the period between January 2010 and January 2015. Fifty-three patients met the inclusion criteria and were followed up till January 2020. RESULTS A total of 766 lymph nodes were excised from the patients. Thirty-two patients (60.4%) had a LN yield of ≥12 LNs with a mean LNR of 0.257 ± 0.27. Multivariate analysis of outcomes showed that LNR was significantly correlated with both DFS (p = 0.015) and OS (p = 0.024). Moreover, the number of resected LNs was also associated with statistically significant relationship with the DFS and OS. CONCLUSION Our study confirms the validity of LNR as a prognostic tool that correlates with the survival of patients. Moreover, LNR cutoff values may help predict those of high chance of tumor recurrence.

Abstract
BACKGROUND Hashimoto thyroiditis (HT) is an autoimmune lymphocytic thyroiditis and is the most common form of thyroid inflammatory diseases. The association of HT with papillary thyroid carcinoma (PTC) has been described. PTC is the most common form of malignancy associated with HT. When papillary carcinoma develops on top of Hashimoto thyroiditis, the disease tends to be less aggressive and lymph node and extra-thyroidal invasion are infrequent. RESULTS We retrospectively examined the pathological features of our patients who were diagnosed with concomitant HT and thyroid cancer. In Egyptian patients, PTC was the main type of malignancy associated with HT (96.2%) and was often multifocal (46.2%). In contrast to the published literature, lymph node invasion and extra-thyroidal extension were as frequent in association with HT as in other cancer cohorts. We also observed the frequent occurrence of Hürthle cell metaplasia (23.1%) and the appreciable incidence of aggressive histological types of PTC (32%). CONCLUSION Thyroid carcinoma with HT may have some aggressive features in areas with endemic goiter background.

BACKGROUND Stomach cancer is a curative disease in early stages. The optimal extent and approach for gastric resection are still evolving. PATIENTS AND METHODS In this study, we examined the value, as well as, the predictors of omental disease spread, retrospectively, in a group of patients with gastric cancer who attended the Oncology Center, Mansoura University, in the period between January 2006 and April 2017. RESULTS Nodal metastasis, especially heavy disease (N2 and beyond), and advanced stage are predictors of the presence of omental disease. However, neither overall nor disease-free survival is affected by omental infiltration. CONCLUSION Omental resection will continue being an integral part of gastric resection, but the level of omental cutting needs further studies.

Abstract
Background
Surgical myectomy for (HOCM) results in complex structural and functional changes. “Remodelling” in different cardiac chambers. To date, changes in the Right versus the left Ventricle have not been studied.
Methods
Fourty five patients (mean age = 32±16, 68% males) who underwent extended septal myectomy for LVOTO and Fourty “normal” controls (mean age = 32±12 years, 52% males) were studied by cardiac magnetic resonance imaging (CMR). The patients were studied pre-operatively and 6–18 months post-operatively (median = 9 months). The images were analysed by both commercial and in-house software.
Results
After myectomy. Follow up CMR showed changes in RV mass (21±5 to 23±7) g/m2, volume (60±15 to 66±12) ml/m2 and shape using 3 different methods. RV deformation parameters showed significant changes with circumferential strain (−8±2 to −14±4), filling (38±16 to 62±19) ml/s/m2 and ejection rate (−44±17 to −75±22). Changes in RV were substantially higher than those observed in the LV (Figure. 1, Table. 1). All patients reported significant symptomatic improvement with 31 (78%) patients in NYHA class I and 9 (22%) in class II at follow up. Significant reduction in peak gradient across the LVOT by 75%.

Conclusion
LV septal myectomy is followed by structural and functional remodelling which is more extensive in the right than the left ventricle. The clinical significance of these findings needs further study.

Abstract
Background Modified radical mastectomy (MRM) is the most common surgery for cancer breast that is associated with marked postoperative pain. Effective control of this pain suppresses the surgical stress response and decreases the opioids and general anesthetics' needs. This study compared the erector spinae plane (ESP) block and the pectoral plane (PECS) block effects on the opioid consumption postoperatively, stress response, fentanyl needs intraoperatively, pain scores, and incidence of complications in female patients subjected to MRM surgery. Patients and Methods Fifty patients were allocated randomly and divided into two groups. Forty-seven patients were included in the final analysis after exclusion. ESP block group (E group, n = 24) received 20 mL of 0.25% levobupivacaine plus 0.5 μ/kg dexmedetomidine that was injected in-between erector spinae muscle and transverse process. PECS block group (P group, n = 23) received 30 mL of 0.25% levobupivacaine plus 0.5 μg/kg dexmedetomidine divided into 10 mL that was injected between the two pectoralis muscles in the interfascial plane and the other was 20 mL injected between the serratus anterior and the pectoralis minor. Results Postoperative morphine consumption and stress hormone level in P group were significantly lower than E group. The pain scores and number of patients requested analgesic postoperatively showed significantly higher values in E group. Hemodynamic parameters, fentanyl needed intraoperatively and the incidence of postoperative complications recorded no significant difference between the two groups. Conclusion The current study demonstrated that PECS block provides better quality of analgesia than ESP block in patients subjected to MRM operations.

Abstract
Background: Laparoscopic hysterectomy operations especially for obese patients necessitate Trendelenburg position and pneumoperitoneum with carbon dioxide, which could affect cardiac and pulmonary functions. The present study aimed to compare the impact of pressure-controlled ventilation with volume-guaranteed (PCV-VG) and volume-controlled ventilation (VCV) with equal ratio ventilation (ERV), i.e., I: E ratio of 1:1 on hemodynamics, respiratory mechanics, and oxygenation. Patients and Methods: Eighty females with body mass index (BMI) >30 kg/m2 and with physical status American Society of Anesthesiologists Classes I and II undergoing laparoscopic hysterectomy were allocated randomly to either PCV-VG (Group P) or VCV with ERV (Group V). The ventilation parameters, hemodynamics, and arterial blood gases (ABGs) analysis were recorded at four times: (T1): after the anesthetic induction while in supine position by 10 min, (T2 and T3): after the CO2 pneumoperitoneum and Trendelenburg positioning by 30 and 60 min, respectively, and (T4): after desufflation and resuming the supine position. Results: The peak inspiratory pressure in Group P recorded significant lower values than in Group V while the dynamic compliance was greater significantly in Group P than in Group V. No significant differences were reported as regards the ABG analysis, oxygenation, and hemodynamic data between both groups. Conclusion: In obese females undergoing laparoscopic hysterectomy surgeries, PCV-VG was superior to VCV with ERV as it provided higher dynamic compliance and lower peak inspiratory pressure that could be preferable, especially in those patients in whom cardiopulmonary function could be more susceptible to impairment.

Abstract
Purpose Revolutions have occurred over the last 3 decades in the management of patients with colorectal cancer. Most advances were in rectal cancer surgery, especially after the introduction of the total mesorectal excision (TME) by Heald. However, no parallel advances regarding colon cancer surgeries have occurred. In 2009, Hohenberger introduced a new concept trying to translate the survival advantages of TME to patients with colon cancer. This relatively new concept of a complete mesocolic excision (CME) with central vascular ligation (CVL) in the management of patients with colon cancer represents an evolution in operative technique. We performed a comparative study between CME with CVL and conventional surgery for patients with colon cancer at Italian and Egyptian cancer centers, considering surgical quality and clinical outcome. Methods Seventy-nine Egyptian patients underwent conventional surgery (non-CME group) while 52 Italian patients underwent CME with sharp dissection between the embryological planes and CVL of the supplying vessels (CME group). Results Significantly better results were observed in terms of lymph node yield (CME group: 22.5 vs. non-CME group: 12; P < 0.0001) and lymph node ratio (CME group: 0.03 vs. non-CME group: 0.22; P < 0.0001). Regarding surgical morbidity, no significant difference was noted (CME group: 2 vs. non-CME group: 5; P < 0.702). Conclusion CME appears to be a safe procedure when performed by experienced hands through proper embryological planes. It also provides a superior specimen, with a higher lymph node yield, which consequently affects the lymph node ratio. Eventually, CME with CVL should be increasingly adopted and studied more deeply.

Abstract
BACKGROUND Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world. METHODS This international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231. FINDINGS Between Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9·4%] of 7339 patients), middle (549 [14·0%] of 3918 patients), and low (298 [23·2%] of 1282) HDI (p<0·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17·8%] of 574 patients in high-HDI countries; 74 [31·4%] of 236 patients in middle-HDI countries; 72 [39·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1·60, 95% credible interval 1·05-2·37; p=0·030). 132 (21·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16·6%) of 295 patients in high-HDI countries, in 37 (19·8%) of 187 patients in middle-HDI countries, and in 46 (35·9%) of 128 patients in low-HDI countries (p<0·001). INTERPRETATION Countries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication.

Abstract
BACKGROUND The prognosis of right colon cancer remains disappointing. Complete mesocolic excision (CME) with central vascular ligation (CVL), based on the same oncological principles of total mesorectal excision, has been speculated to result in a better outcome. To evaluate the oncological adequacy of CME with CVL, we carried out a comparative study with propensity score-matched analysis between two different surgical procedures performed at Italian and Egyptian University cancer centers. METHODS Forty-six Egyptian patients underwent conventional right hemicolectomy, while eighty-eight Italian patients underwent CME with sharp dissection between the embryological planes, exposure of the superior mesenteric vessels with extended lymphadenectomy, and CVL. RESULTS All operations were successful with no increase in postoperative complications (10% in the patients undergoing CME vs. 19.5% in Egyptian patients). Number of harvested nodes (21 vs. 13) and lymph node ratio (0.08 vs. 0.22) were significantly different in patients undergoing CME (P=0.0001 and P=0.005, respectively). In these patients, the risk of cancer relapse was reduced to as much as one third (8% vs. 22%), even in node-positive tumors, and locoregional recurrences were never experienced. The classic operation was significantly associated with poor outcome (5-year disease-free survival rates were 89.2% in the group undergoing CME and 49.1% in the classic group, P=0.02). Propensity score-matched analysis warranted optimal balance and confirmed overall results. CONCLUSIONS Right colon cancer patients undergoing CME benefitted from more oncological adequacy, with no increased postoperative complication rate, a decreased locoregional recurrence rate, and a better long-term outcome than patients operated on with the conventional procedure.

Abstract
INTRODUCTION Idiopathic granulomatous mastitis (IGM) is a chronic inflammatory condition that is confused with cancer. It usually affects women in child bearing age. The exact aetiology and pathogenesis are still unknown, and the optimal therapeutic modality has not yet been established. Treatment most frequently includes Antibiotics, corticosteroids and immunosuppressant, surgical excision, and even mastectomy. MATERIAL AND METHODS We studied a thirty cases diagnosed with IGM in our locality to find out the leading risk factors and the outcome of our surgical approach which involves excision of the lesion in continuity with duct system. Patients demographic data, history related to lactation and outcome were recorded. RESULTS All patients were parous women with history of previous breast feeding for all kids. Twenty-six patients (86.66%) had a history of early incomplete nursing care to the affected breast. After our surgical approach, Twenty eight (93.3%) patients showed fast recovery with no detectable recurrences in the median follow up period (18 months) with acceptable cosmoses. CONCLUSION History of breast feeding together with early failure of complete nursing from a single breast is the most important risk factors for development of IGM in young aged women. Surgery plays an important role in treating IGM, however, it should be directed towards excision of the present mass (s) together with the pathological and colonized duct system.

Abstract
Aim: The aim of this study was to assess the effectiveness of transrectal sectional sonography (TRSS) in the diagnosis and treatment of prostatic abscess. Materials and Methods: Eighteen patients with prostatic abscesEs were the material of the present study. The criteria of abscess collection within the prostate gland and the periprostatic tissues were confirmed by TRSS, which guided the aspiration in all patients. Results: Diagnosis and transperineal needle aspiration of prostatic abscesses were successful in all cases. After the second puncture procedure, recurrence noted in 2 (11.1%) out of 18 patients, who were further subjected to transurethral deroofing under TRSS vision. The amount of pus drained ranged between 3.6 and 29.3 mL (mean: 15.1 mLSD ± 1.5), compatible with the estimated volume by virtual organ computer-aided analysis three-dimensional measurements. The most frequently involved organism was Escherichia coli. All patients received intravenous antibiotics (third generation cephalosporin) after the midstream urine analysis and further proper antibiotics, according to the aspirated pus culture and sensitivity. Conclusions: Transrectal sectional sonography could be a more reliable method in the diagnosis of prostatic abscesses. It can provide precise needle-guides into the best drainage location of the abscess cavity and justify transurethral unroofing if persistent recurrence is there.

Abstract
Purpose: The aim of this study is to evaluate the role of ureteric stents in relieving obstruction and improvement of kidney function in patients with obstructive uropathy. Materials and Methods: This study involved 138 patients with obstructive uropathy with age ranged from 2 months to 73 years. Patients classified into two groups: Group (I): Includes 57 patients (41.3%), ureteric stents fixed to them; and Group (II): Includes 81 patients (58.6%) managed by other treatment modalities. All patients underwent clinical assessment, Laboratory and radiologic investigations: At presentation and postoperative. These included: Complete urine analysis, urine culture and sensitivity, serum creatinine, serum urea nitrogen, serum uric acid, serum sodium (Na), serum potassium (K), Fasting blood glucose level and blood picture and plain X-ray (KUB), abdominal ultrasonography (US), diuretic renography and retrograde pyelography. Results: Renal glomerular filtration rate (GFR) was used as an indicator for improvement of renal function after fixation of ureteric stent. In group I: 56 (71.8%) kidneys showed significant recovery compared to 61 kidneys (66.3%). In group II, there is statistically significant relation between renal perfusion and renal recovery (P < 0.004), statistically significant relation between parenchymal thickness and recovery in both groups (P < 0.0002), statistically significant relation between degree of corticomedullary differentiation and recovery (P < 0.0003) and statistically significant relationship between hemoglobin levels at presentation and the recoverability (P < 0.002). Conclusion: The predictors of renal recoverability revealed that ureteral stents alone can help in regaining renal function and significant improvement of clinical condition in patients with obstructive uropathy.

Abstract
Objectives: Trans-rectal ultrasound (TRUS) is a safe, cost-effective, radiation-free imaging modality for evaluation of prostate. But unfortunately, hemospermia is known to be associated with TRUS–guided prostate biopsy. The aim of this study is to measure the incidence and risk factors of hemospermia in patients undergoing TRUS. Patients and Methods: A prospective observational study involving patients undergoing TRUS for suspected prostate cancer has been conducted at Al-Hussein and Sayed Galal Hospitals. Forty patients were included in the study. Results: Most men (90% = 36 patient) undergoing TRUS-guided prostatic biopsy, who were able to ejaculate, experienced hemospermia, which was associated with some degree of anxiety. The mean duration of hemospermia was 4 (±1.4) weeks. The number of ejaculations before the complete resolution of hemospermia was 6 (±5.6). None of the clinical and pathological factors was a significant predictor of the duration of hemospermia. Conclusion: Patients should be adequately counseled before TRUS-guided prostatic biopsy to avoid anxiety and alterations in sexual activity.

Abstract
OBJECTIVES To present our experience with extracorporeal shock wave lithotripsy (ESWL) in patients with anomalous kidneys and to determine the factors that may influence the stone-free rate in such patients. METHODS From February 1989 to February 2000, 198 patients were treated for urolithiasis in anomalous kidneys using ESWL. The mean patient age (SD) was 40.48 (11.53) years. The kidneys were horseshoe in 49 (24.7%), malrotated in 120 (60.6%), and duplex in 29 (14.7%). All patients were treated on an outpatient basis using two second-generation lithotripters (Dornier MFL 5000 and Toshiba Echolith). Pretreatment auxiliary measures were required in 6 patients (3%). Follow-up data were recorded at 3 months. The statistical analysis was performed using the chi-square and Mann-Whitney U tests, with differences considered statistically significant if P <0.05. RESULTS The mean stone length (SD) was 13.54 (5.49) mm. The stones were single in 148 (74.7%), of new onset in 155 (78.3%), and on the right side in 82 (41.4%). All stones, but 5 (2.5%), were radiopaque. The overall stone-free rate was 72.2%. Neither the type of renal anomaly nor the type of lithotripter had any impact on the stone-free rate (P >0.05). Stone burden (length and number) had a significant influence on the stone-free rate (P <0.05). No extraordinary complications were recorded. Steinstrasse developed in 7 patients (3.5%). No deterioration of renal function or configuration was detected. CONCLUSIONS ESWL is safe and reliable for treatment of urolithiasis in anomalous kidneys. It should be the primary therapy when the stones are less than 20 mm. The ESWL outcome is comparable for normal and anomalous kidneys when the calculus size is considered.
