Prevalence and associated factors of sexual dysfunction in female hemodialysis patients: first report from Somalia.

BACKGROUND: Sexual dysfunction is frequent in female hemodialysis patients and is related to poorer quality of life. It is often a neglected topic associated with marked distress and interpersonal difficulties. OBJECTIVE: Few studies are reported from Sub-Saharan African Countries (SSA) regarding female sexual dysfunction (FSD) in (HD) patients. The study aims to explore the prevalence and associated factors of FSD in female HD at a sole dialysis centre in Somalia. METHOD: Over a one-month period, a cross-sectional study was conducted among women with end-stage renal disease aged 18-50 years who were undergoing a dialysis program for at least three months at the dialysis center of our hospital. The participants were married, and they were living with their partners. Data regarding the sociodemographic features, clinical characteristics, frequency of sexual intercourse per week, and the Female Sexual Function Index (FSFI) scores were collected using a standard face-to-face interview questionnaire. RESULTS: During the study period, a total of 115 participants were eligible for the study's inclusion criteria. The mean patient age was 38.5 ± 9.3 years. The most common cause of ESRD was diabetes, which accounted for 53%, followed by hypertension (26.1%) and glomerulonephritis (9.6%). The mean duration of dialysis was 2.9 ± 1.4 years, and approximately two-thirds of the participants (62.5%) were in the program for more than three years. Regarding the frequency of sexual intercourse, 61.7% of female participants performed sexual intercourse less than once time/a week. The prevalence of FSD was 92.2% (n = 106) of all participants. The mean FSFI score of the participants was 16.05 ± 4.48. Longer duration of dialysis program (i.e., more than four years), increasing age (i.e., > 35 years), those with diabetes had scored lower overall FSFI scores. CONCLUSION: The prevalence of female sexual dysfunction among Somali female hemodialysis patients was very high, representing a significant problem in end-stage renal disease (ESRD). Our study findings revealed that increasing age, diabetes, and duration of dialysis negatively impact female sexual function and are significantly associated with FSD.

Do Attitude, Awareness and Intention to Perform Female Genital Mutilation or Cutting for Their Daughters of Women Healthcare Providers Differ from Mothers in Somalia?

Aim: This study aimed to determine whether there were differences in attitude, awareness, and intention to perform female genital mutilation or cutting for their daughters in the future between female healthcare providers and mothers. Methods: A comparative cross-sectional study design was used. Results: A total of 508 women were included in the study. Of the participants, 68.7% (n = 349) were mothers (Group I) who visited the hospital and 31.3% (n = 159) were women healthcare professionals (Group II) [27% (n = 137) nurses and 4.3% (n = 22) doctors]. It was found that 8 (1.6%) of the participants did not have FGM/C and the FGM/C ratio was lower in group II (95%) than in group I (100%) (p < 0.001). In group I, 99.7% (n = 299) of the participants and 30.6% (n = 19) of those in group II reported intending to perform FGM for their daughters in the future (p < 0.001). The reasons for FGM/C most cited by participants were a traditional rite of passage into womanhood (78%), religious requirement (69.3%), and preservation of their virginity until marriage (59.3%). "Stop FGM" was given as a message on FGM/C by 60% of the participants (n = 79) who answered (n = 127, 100%) to open-ended questions. Conclusion: The results of this study show that female health professionals with higher education and monthly income had less positive perception of their FGM/C and less intention to allow their daughters to undergo FGM/C.

Comparison of the Conventional PNL with Ecirs in the Treatment of Complete Staghorn Kidney Stones.

OBJECTIVE:  To analyse the results of conventional percutaneous nephrolithotomy (PNL) and endoscopic combined intrarenal surgery (ECIRS) in treating complete staghorn kidney calculi. STUDY DESIGN:  A comparative study. Place and Duration of the Study: Department of Urology, University of Health Sciences, Diskapi Yildirim Beyazit Training and Research Hospital, Ankara, Turkey, between January 2007 and January 2022. METHODOLOGY:  Clinical data and surgical outcomes of the adult patients who underwent conventional PNL or ECIRS were retrospectively reviewed. Two patient groups were compared regarding the fluoroscopy time, the number of access, surgical time, duration of hospitalisation, haemoglobin (Hb) reduction, complication, and stone-free rates.  Results: There were 132 renal units in the conventional PNL (Group 1) and 45 renal units in the ECIRS group (Group 2). The comparative analysis revealed that fluoroscopy time, surgical time, duration of hospital stay, number of access, and the Hb drop were significantly lower in the ECIRS group compared to the conventional PNL group. Although stone-free rates were 48.5% in Group 1 and 64.4% in Group 2, p=0.064 and p>0.05 respectively). The median value of the complication grade was 1 (1-7) in Group 1 and 1 (1-5) in Group 2, (U=2446.5, p=0.026).  Conclusion: The ECIRS is a successful and more secure surgical method for treating complete staghorn stones than PNL. KEY WORDS:  PNL, ECIRS, Staghorn, Kidney, Stone.

Current practice of live donor nephrectomy in Turkey.

BACKGROUND: Over the last few years, the deceased donor organ donation rate was declined or remained stable, whereas the live donor organ donation rate has increased to compensate for the demand. Minimally invasive techniques for live donor nephrectomy (LDN) have also improved the live donor kidney donation rates. This increase has led to an interest in the surgical procedures used for LDN. AIM: To evaluate the LDN techniques performed in Turkey, the structure of surgical teams, and the training received. Additionally, the number of kidney transplantations at different centers, the surgeon experience level, differences in surgical approach during donor surgeries, and outcomes were assessed. METHODS: A questionnaire was sent to the Turkish Ministry of Health-accredited transplant centers. It inquired of the number of LDN surgeries, surgical techniques, complications, optimization protocols, the experience of surgeons, and the training. Descriptive statistics were outlined as follows: Discrete numeric variables were expressed as medians (minimum-maximum), while categorical variables were shown as numbers and percentages. As a result of the goodness-of-fit tests, if the significance of the differences between the groups in discrete numerical variables for which the parametric test statistical assumptions were not met, data were analyzed with the Mann Whitney U test and the χ 2 test. RESULTS: The questionnaire was sent to 72 transplant centers, all of which replied. Five centers that reported not performing LDN procedures were excluded. Responses from the remaining 67 centers were analyzed. In 2019, the median number of kidney transplants performed was 45, and the median number of kidney transplants from living donors was 28 (1-238). Eleven (16.5%) centers performed 5-10, while 34 (50.7%) centers performed more than 100 live donor kidney transplants in 2019. While 19 (28.4%) centers performed the LDN procedures using the open technique, 48 (71.6%) centers implemented minimally invasive techniques. Among the centers preferring minimally invasive techniques for LDN, eight (16.6%) used more than one surgical technique. The most and the least common surgical techniques were transperitoneal laparoscopic (43 centers, 89.6%) and single port laparoscopic LDN (1 center, 2.1%) techniques, respectively. A positive association was found between the performance of minimally invasive techniques and the case volume of a transplant center, both in the total number and live donor kidney transplants (15 vs 55, P = 0.001 and 9 vs 42, P ≤ 0001 respectively). The most frequently reported complication was postoperative atelectasis (n = 33, 49.2%). There was no difference between the techniques concerning complications except for the chyle leak. CONCLUSION: Turkish transplant centers performed LDN surgeries successfully through various techniques. Centers implementing minimally invasive techniques had a relatively higher number of live donor kidney transplants in 2019.

Burned-out germ cell tumor presenting with acute abdomen.

Acute abdomen is a serious condition frequently encountered in the emergency departments (ED). There are various etiologies causing acute abdomen, most common being acute appendicitis; however, there are rare causes of acute abdomen as well and one should keep them in mind while handling a patient with unusual clinical features. We herein present a 26-year-old male, with no past medical or surgical history, presenting with acute abdominal pain and distension to the ED. He was found to have a large vascular retroperitoneal mass on computed tomography which had invaded and perforated the duodenum thus causing the acute presentation. Repair of the duodenal perforation and sampling of the mass were performed in terms of surgical management. Pathology results revealed the mass originating from a burned out testis yolk sac tumor with embryonal carcinoma component. Although the original tumor had regressed at the testis, its metastasis at the retroperitoneal area had caused the clinical condition. This entity is described as the retroperitoneal metastasis of a burned-out testicular tumor. Few cases presenting with gastrointestinal bleeding secondary to invasion of the retroperitoneal metastasis have been reported. However, this is the first case in the literature presenting with duodenal perforation and acute abdomen. Sampling of the retroperitoneal tumor for histopathological diagnosis during the immediate surgical intervention facilitates the diagnostic management in these cases. Although scrotal examination combined with testis tumor marker assessments is essential for optimal patient management, the possibility of a burned-out testicular tumor with normal scrotal examination should always be kept in mind.

Vitamin D deficiency may predispose patients to increased risk of kidney transplant rejection.

BACKGROUND: Vitamin D deficiency occurs in more than 80% of kidney transplant recipients. Its immunomodulatory effects can predispose transplant recipients to rejection and chronic allograft nephropathy (CAN). This study determined the association between serum 25 (OH) vitamin D, biopsy-proven allograft rejection, and CAN rates. AIM: To determine the relationship between serum 25 (OH) vitamin D level and biopsy-proven allograft rejection and CAN rate in renal transplant recipients. METHODS: Adult renal transplant recipients followed at the clinic between January 2013 and 2018 were included. Recipients requiring graft biopsy due to declined function, hematuria, and proteinuria were reviewed. The two groups were compared regarding collected data, including the biopsy results, immunologic parameters, vitamin D, parathyroid hormone (PTH), phosphorus, albumin levels, and graft function tests. RESULTS: Fifty-two recipients who underwent graft biopsy met the inclusion criteria. In all, 14 recipients had a vitamin D level > 15 ng/mL (group 1) vs ≤ 15 ng/mL (group 2) in 38. In total, 27 patients had biopsy-proven rejection, and 19 had CAN. There was only 1 recipient with biopsy-proven rejection in group 1, whereas there were 24 patients with rejection in group 2. The rejection rate was significantly higher in group 2 than in group 1 (P < 0.001). Four patients were diagnosed with CAN in group 1 vs fifteen in group 2. There was no significant difference in the CAN rate between the two groups. PTH was higher at the time of graft biopsy (P = 0.009, P = 0.022) in group 1 with a mean of 268 pg/mL. Donor-specific antibodies were detected in 14 (56.0%) of the recipients with rejection. Vitamin D level was 9.7 ± 3.4 ng/mL in the rejection group vs 14.7 ± 7.2 in the non-rejection group; this difference was statistically significant (P = 0.003). The albumin levels were significantly lower in patients with rejection than in those without rejection (P = 0.001). In univariate regression analysis of risk factors affecting rejection, sex, serum vitamin D, phosphorus and albumin were found to have an impact (P = 0.027, P = 0.007, P = 0.023, P = 0.008). In multivariate regression analysis, the same factors did not affect rejection. CONCLUSION: The serum 25 (OH) vitamin D level in kidney transplant recipients remained low. Although low serum vitamin D level emerged as a risk factor for rejection in univariate analysis, this finding was not confirmed by multivariate analysis. Prospective studies are required to determine the effect of serum vitamin D levels on allograft rejection.

An isolated traumatic renal artery pseudoaneurysm treated by renal artery stent insertion: a case report presenting a nephron-sparing approach.

Penetrating or blunt traumas can rarely lead to renal artery pseudoaneurysms (RAPs). Renal parenchymal lacerations usually accompany them, and nephrectomy is performed in these cases. Although angioembolization of the renal artery can negate the need for nephrectomy while treating the RAP, it is not a nephron-sparing procedure. Herein, we present a case of isolated (i.e. without accompanying renal laceration) left RAP. During conservative follow-up, the RAP enlarged, and subsequently, it was treated by renal artery stent insertion. An expandable covered stent was used during this procedure. The renal function was preserved without experiencing any complications.

Somalian women with female genital mutilation had increased risk of female sexual dysfunction: a cross-sectional observational study.

Studies regarding the impact of female genital mutilation/cutting (FGM/C) on sexual function are scarce. This study is the first to explore the rate of female sexual dysfunction (FSD) among Somalian women who underwent FGM and its association with different FGM types. This study was carried out among women with a history of FGM who visited our clinic for a medical check-up. It relied on data including socio-demographic features, type of FGM determined by an examination, and the Female Sexual Function Index (FSFI) scores. Overall, 255 women were included. While 43.9% (n = 112) of the respondents had a history of Type 3 FGM, 32.2% had Type 2 (n = 82), and 23.9% had Type 1 (n = 61) FGM. Among all patients, 223 had FSD (87.6%). There was a significant association between the FGM type and FSD (p < 0.001). The mean total FSFI score for the patients with Type 1, 2, and 3 FGM was 22.5, 19.7, and 17.3, respectively, all indicating FSD. The FSD is prevalent among mutilated Somalian women. Patients with Type 3 FGM had the lowest mean total FSFI scores indicating that the impact on sexual function was correlated with the extent of tissue damage during FGM.

Utilization of Internet Resources by Surgeons for Continuous Professional Development in the Era of Prevailing COVID-19 Pandemic: Trends and Obstacles.

Background: To investigate the use of internet resources by surgeons for continuing professional development (CPD). Results: This cross-sectional study was carried out between July 1, 2021, to October 31, 2021, at the Department of Medicine, Health Sciences University Diskapi Yildirim Beyazit Training and Research Hospital, Ankara, Turkey, with participants from nine surgical specialties: General surgery, neurosurgery, orthopedics, urology, plastic surgery, ear-nose-throat surgery, cardiovascular surgery, ophthalmology, and anesthesiology. All study participants were asked to complete a questionnaire comprising 23 questions regarding their age, duration of work experience, appointment status, venue, and time spent on internet resources and preferred online resources for CPD purposes. In addition, participants were divided into two groups according to their appointment status: academic faculty and staff surgeons. Data analysis was performed using IBM SPSS Statistics version 17.0. The target population consisted of 216 specialists. The survey was completed by 204 (94.4%) surgical specialists. The majority of the specialists (n = 137, 67.2%) reported using the internet for work-related purposes every day. Daily time spent on internet resources was reported to be 30-60 min by 39.2% (n = 80) participants, whereas 52 (25.5%) reported spending less than 30 min. The participants wished to spend more time on internet resources. The majority of surgeons found the hospital and home equally effective in using the internet and preferred to engage alone. The mean age, English language level, usage of online resources, and the attitude score toward the perceived credibility and usefulness of e-resources were significantly higher in the academic faculty group than staff surgeons (p < 0.005). On the other hand, the use of Google/Google scholar was similar between the two groups (p = 0.192). Technical difficulties such as slow internet, need for website registration, and article fees were considered drawbacks for internet resources among all the participants. Conclusions: This study showed that most surgeons use internet resources daily for CPD and stated they would like to engage longer despite technical difficulties. Institutions should address these technical difficulties.

Clinical Features and Surgical Outcomes of the Children With Urolithiasis at a Tertiary Care Hospital: First Report From Somalia.

Introduction: There are very few studies regarding pediatric urolithiasis (PU) reported from Africa, and to date, no data have been presented from Somalia. This study evaluated the sociodemographic and radiological characteristics, treatment, and outcome data of the PU patients treated at Somalia's only tertiary care center. Method: The data of all patients diagnosed with urolithiasis during a 6-year period were reviewed. Only pediatric (age <18) urolithiasis patients were included. Demographic parameters, radiological features, stone characteristics, treatment, and outcome data were collected and analyzed. Results: Overall, 227 (127 male, 100 female) patients were included. The rate of PU was 8.1%. The mean patient age was 12.7 ± 3.2. More than two-thirds of the patients (n = 161, 70.9%) were adolescents. The stones were located in the kidney in 50.7%, the ureter in 33%, and the bladder in 14.5%. Distal ureteral stones (36%) accounted for the majority of ureteral stones, followed by the ureterovesical junction (26.7%) and proximal ureteral (24%) stones. The mean stone size was 16.2 mm. Most (42.3%) stones had a 10-20 mm diameter, while 23.3% were sized between 6 and 10 mm. Renal insufficiency was present in 5.3%. Among 227 patients, 101 (44.5%) underwent minimally invasive procedures including ureterorenoscopic lithotripsy (n = 40, 18%), retrograde intrarenal surgery (n = 30, 13.2%) and percutaneous nephrolithotomy (n = 31, 14%). Open pyelolithotomy was the most common surgery performed (n = 53, 22.3%). Surgical site infection developed following 3.5% of the open surgery cases. The stone-free rate was 91.3%. It was significantly higher in open cases (98%) compared to the cases performed via a minimally invasive approach (83%) (p = 0.02). Conclusion: In Somalia, PU is more common than in many other countries. Open surgery continues to be the primary treatment modality for children with urolithiasis due to the restricted endourology resources. However, minimally invasive approaches have evolved over the last years.

Management of a patient with a double J stent knotted at the mid-portion.

Ureteral stents are safe, and because of their widespread usage, complications associated with stenting increased. The knotting of the ureteral stent is an uncommon complication. Until today, only three cases of knotting at the mid-portion and distal ends of the ureteral stents were reported. Herein, we report a rare case of a downward migrated ureteral stent with a knot in its middle portion at the level of the distal ureter in a 25-year-old female patient. Her knotted stent was successfully removed by guidewire insertion and ureteroscopy under fluoroscopic guidance.

Parastomal skin metastasis in a patient with history of urinary bladder cancer.

Transitional cell cancer of the urinary bladder very rarely metastasize to the skin. Herein, we present a patient with urinary bladder cancer who underwent radical cystoprostatectomy and ileal conduit surgery. During follow-up, he developed lung and skin metastases. However, the latter presented as a solitary sessile polypoid lesion at the parastomal area.

Factors affecting the effectiveness and success of retrograde holmium laser endopyelotomy as the primary treatment of ureteropelvic junction obstruction in adults.

PURPOSE: To evaluate the factors affecting the effectiveness, safety, and success of retrograde holmium:yttrium-aluminum-garnet laser endopyelotomy as the primary treatment of ureteropelvic junction obstruction in adults. METHODS: Adult patients who underwent retrograde holmium:yttrium-aluminum-garnet laser endopyelotomy as the primary treatment of ureteropelvic junction obstruction between January 2012 and June 2016 at our clinic were retrospectively analyzed. Success was defined as the relief of symptoms and the resolution of obstruction, as assessed via radiography. Factors affecting success were analyzed, such as the clinical characteristics, procedural outcomes, complications, and the type of ureteroscopy used in the procedure. RESULTS: Procedural success was achieved in 29 (74.4%) out of 39 patients, with a mean age of 38.3 ± 12.3 years during a median follow-up duration of 44 (33-65) months. Failure occurred at a median of 4.5 (3-22) months. It was detected that the presence of primary obstruction, ipsilateral kidney function being >30% of normal, and the length of obstruction being <1 cm positively affected procedural success (p = 0.009, p = 0.011, and p = 0.019, respectively). In the postoperative period, two Grade I and four Grade II complications were observed according to the Clavien-Dindo classification. There was a difference only in the operation time between semirigid (24) and flexible ureteroscopes (15), with the operation time being shorter with the use of a semirigid ureteroscope than with the use of a flexible uteroscope (p < 0.001). CONCLUSION: Retrograde holmium:yttrium-aluminum-garnet laser endopyelotomy is a minimally invasive method that can be used effectively and safely as the primary treatment of patients with ureteropelvic obstruction, when long-term results are also taken into consideration. The decision of performing laser endopyelotomy should be made after a detailed evaluation of the characteristics of the patient as well as of the obstruction.

COVID-19 infection in a kidney transplant recipient-special emphasis on pharmacokinetic interactions: A case report.

BACKGROUND: Solid organ transplant recipients are considered to be at high-risk of developing coronavirus disease 2019 (COVID-19)-related complications. The optimal treatment for this patient group is unknown. Consequently, the treatment of COVID-19 in kidney transplant recipients should be determined individually, considering patient age and comorbidities, as well as graft function, time of transplant, and immunosuppressive treatment. Immunosuppressive treatments may give rise to severe COVID-19. On the contrary, they may also lead to a milder and atypical presentation by diminishing the immune system overdrive. CASE SUMMARY: A 50-year old female kidney transplant recipient presented to the transplant clinic with a progressive dry cough and fever that started three days ago. Although the COVID-19 test was found to be negative, chest computed tomography images showed consolidation typical of the disease; thus, following hospital admission, anti-bacterial and COVID-19 treatments were initiated. However, despite clinical improvement of the lung consolidation, her creatinine levels continued to increase. Ultrasound of the graft showed no pathology. The tacrolimus blood level was determined and the elevation in creatinine was found to be related to an interaction between tacrolimus and azithromycin. CONCLUSION: During the COVID-19 pandemic, various single or combination drugs have been utilized to find an effective treatment regimen. This has increased the possibility of drug interactions. A limited number of studies published in the literature have highlighted some of these pharmacokinetic interactions. Treatments used for COVID-19 therapy; azithromycin, atazanavir, lopinavir/ritonavir, remdesivir, favipiravir, chloroquine, hydroxychloroquine, nitazoxanide, ribavirin, and tocilizumab, interact with immunosuppressive treatments, most importantly with calcineurin inhibitors. Thus, their levels should be frequently monitored to prevent toxicity.

Comparison between dorsal onlay and one-sided dorsolateral onlay buccal mucosal graft urethroplasty in long anterior urethral strictures.

OBJECTIVE: To compare dorsal onlay (conventional Barbagli) and one-sided dorsolateral onlay (Kulkarni technique) buccal mucosa substitution urethroplasty techniques for the treatment of long anterior urethral strictures. METHODS: Demographic data, treatment outcomes and success rates of patients who underwent either conventional Barbagli or Kulkarni urethroplasty for the treatment of an anterior urethral stricture longer than 8 cm between January 2010 and March 2019 in our center were retrospectively reviewed. RESULTS: Demographic parameters of patients who underwent the conventional Barbagli (n = 37) or Kulkarni procedure (n = 31) did not differ. The mean surgical duration and hospital stay were shorter for patients treated with the Kulkarni technique (179.5 ± 30.0 and 3.5 ± 1.2 vs 195.5 ± 28.9 min and 4.4 ± 1.8 days; P = 0.037, P = 0.002). Mean intraoperative blood loss and perioperative complication rates were signficantly lower in patients who underwent the Kulkarni technique than those who underwent the conventional Barbagli technique (164.3 ± 62.9 vs 202.4 ± 78.1 mL; P = 0.033 and 16.1% vs 37.8%; P = 0.046). The mean follow-up time period was 59.8 ± 24.7 and 63.5 ± 26.8 months for Kulkarni and conventional Barbagli techniques, respectively. Success rates based these follow-up time periods were 27 (87.1%) and 26 (70.3%) for the Kulkarni and conventional Barbagli techniques, respectively. CONCLUSION: The Kulkarni technique should be more preferred for the treatment of long anterior urethral strictures over the conventional Barbagli technique based on surgical outcomes and success rates.

Listening to music during arteriovenous fistula surgery alleviates anxiety: A randomized single-blind clinical trial.

BACKGROUND: Both end-stage renal disease and being wait-listed for a kidney transplant are anxiety-causing situations. Wait-listed patients usually require arteriovenous fistula surgery for dialysis access. This procedure is performed under local anesthesia. We investigated the effects of music on the anxiety, perceived pain and satisfaction levels of patients who underwent fistula surgery. AIM: To investigate the effect of music therapy on anxiety levels and perceived pain of patients undergoing fistula surgery. METHODS: Patients who were on a waiting list for kidney transplants and scheduled for fistula surgery were randomized to control and music groups. The music group patients listened to music throughout the fistula surgery. The State-Trait Anxiety Inventory was performed to assess anxiety, additionally visual analog scale was used to evaluate perceived pain, willingness to repeat the procedure and patient satisfaction. Demographic features, comorbidities, surgical history, basic surgical data (location of fistula creation, duration of surgery, incision length) and intra-operative hemodynamic parameters were recorded by an investigator blinded to the study group. An additional trait anxiety assessment was performed following the surgery. RESULTS: There was a total of 55 patients included in the study. However, 14 patients did not fulfill the criteria due to requirement of sedation during surgery or uncompleted questionnaires. The remaining 41 patients were included in the analysis. There were 26 males and 15 females. The control and music groups consisted of 20 and 21 patients, respectively. With regard to basic surgical and demographic data, there was no difference between the groups. Overall patient satisfaction was significantly higher and intra-operative heart rate and blood pressure were significantly lower in the music group (P < 0.05). Postoperative state anxiety levels were significantly lower in the music group. CONCLUSION: Music therapy can be a complimentary treatment for patients undergoing fistula surgery. It can reduce anxiety and perceived pain, improve intraoperative hemodynamic parameters and enhance treatment satisfaction, thus may contribute to better compliance of the patients.

Transcatheter embolization in pediatric blunt renal trauma: Case report and review of the literature.

This study aims to evaluate the clinical use and outcomes of transcatheter embolization in the setting of pediatric blunt renal trauma cases using an index case and review of the literature. Although the treatment method selection depends on the grade of the trauma and the hemodynamic status of the patient, conservative methods are considered initially in the setting of pediatric blunt renal trauma. Transcatheter embolization, which is a relatively conservative treatment option, is commonly utilized in adult blunt renal trauma patient population; however, experience in the pediatric population is scarce. A seven-year-old male patient was admitted due to grade IV renal injury secondary to blunt abdominal trauma. He was conservatively followed until -on the post-trauma day 15- he developed gross hematuria and an unstable hemodynamic status. A renal angiogram was performed, which revealed right-sided renal inferior segmental artery pseudoaneurysm and arterio-venous fistula. Subsequently, a transcatheter embolization was performed. There were no complications and no permanent renal injury. Review of the literature revealed that the success rate of transcatheter embolization is 89.47% in the setting of pediatric blunt abdominal trauma-related renal injury regardless of the renal trauma grade. Four patients underwent nephrectomy due to a failed transcatheter embolization procedure. There are not any patients who suffered from embolization-related complications. These results suggest that transcatheter embolization can be safely performed in children with renal injuries due to blunt abdominal trauma with high success and low complication rates and preservation of renal function.

Colonic anastomosis can be protected from ischemia reperfusion injury with intra-peritoneal Montelukast treatment.

BACKGROUND: Ischemia reperfusion injury is unavoidable in the setting of transplantation and may lead to primary dysfunction of the transplanted organ. Similarly, intestinal ischemia reperfusion injury may have deleterious effects causing intestinal failure. Montelukast is a selective reversible cysteinyl-leukotriene type 1 receptor antagonist used in clinical practice for its anti-inflammatory effects. In this study, we investigated the effects of Montelukast on colon anastomosis performed after intestinal ischemia reperfusion injury. METHODS: 40 adult male Wistar Albino rats were used. All rats underwent intestinal ischemia reperfusion injury. Afterwards, the entire group was divided into two for either right or left colonic resection and anastomosis. Rats in the control groups were given intra-peritoneal normal saline for 1 week while the animals in the treatment groups were given intra-peritoneal Montelukast (10 mg/kg; 1 ml). All animals were subjected to ischemia reperfusion injury followed by either right or left colonic segmental resection and anastomosis in the first day of the experiment. On postoperative day 7 adhesion scoring, anastomotic bursting pressure, anastomotic tissue hydroxyproline content were assessed for all groups. RESULTS: Significant differences were detected in adhesion scores between the treatment and control groups regardless of the colonic resection site. Anastomotic bursting pressures and hydroxyproline content of the anastomotic sites were significantly higher in the treatment groups when compared with the control groups. Anastomotic tissues treated with Montelukast showed more prominent vascularization in histopathological examinations. CONCLUSION: Montelukast has a potential to attenuate the detrimental effects of ischemia reperfusion injury on intestinal anastomosis.

Effect of histopathologic characteristics on pseudocapsular invasion in the case of partial nephrectomy for renal tumours.

OBJECTIVE: It is aimed to define the existence of pseudocapsular structure on renal tumours, illuminate the relation between pseudocapsular invasion and Fuhrman grade histological type that are among histopathologic prognostic risk factors and determine the relation between surgical margin positivity and existence of pseudocapsular invasion. Sequential partial nephrectomy series and relevant pathological preparations were retrospectively reviewed in order to evaluate these issues. METHODS: The study includes 123 patients diagnosed with T1 renal tumour and treated with partial nephrectomy in between January 2007 and June 2016. Benign angiomyolipoma was excluded due to complete non-existence of pseudocapsule. 99 T1 patients diagnosed with renal cell cancer whose pathological slides can be duly analysed were included in the study. Clinical and pathological details were evaluated for all patients. Existence of pseudocapsule was revealed for all patients. Pseudocapsule invasion was classified by existence of expansive and infiltrative type and non-existence of pseudocapsule invasion. The groups have been assessed by their histopathologic characteristics. RESULTS: Compared to the group in which pseudocapsular invasion was not detected, clear-cell histological subtype was observed more frequently in a statistically significant way in the group with expansive pseudocapsular invasion and infiltrative pseudocapsular invasion respectively (p = 0.017 and p < 0.001). Pathological tumour sizes were found out to be statistically similar (p = 0.874). There was not a statistically significant difference in terms of Fuhrman grade (p = 0.220). There was not a statistically significant difference in terms of surgical positive margin (p = 0.609). CONCLUSION: It was indicated in our study that only the histological subtype affected pseudocapsular invasion in group of patients treated with partial nephrectomy but tumour size, tumour stage, tumour location as well as endophytic and exophytic character did not affect invasion. It has also been revealed that surgical margin positivity is not correlated with pseudocapsular invasion.

Challenges of pancreas transplantation in developing countries, exploring the Turkey example.

Pancreas transplantation significantly improves the quality of life for people with type 1 diabetes, primarily by eliminating the need for insulin and frequent blood glucose measurements. Despite the growing numbers of solid organ transplantations worldwide, number of pancreas transplantations in the developing countries` remain significantly low. This difference of pancreas transplantation practices was striking among the participating countries at the 1st International Transplant Network Meeting which was held in Turkey on 2018. In this meeting more than 40 countries were represented. Most of these counties were developing countries located in Africa, Middle East or Asia. The aim of this article is to identify the challenges and limiting factors for pancreas transplantations in these developing countries, by exploring the Turkish example. The challenges faced by the developing countries are broadly classified in four categories; wait-listing, donor pool, team work and follow up. Under these categorical titles, issues are further discussed in detail, giving examples from Turkish practice of pancreas transplantation. Additionally, several solutions to these challenges have been proposed- some of which have already been undertaken by the Turkish Ministry of Health. With the insight and methods presented in this article, pancreas transplantation should be made possible for the potential recipients in the developing countries.
