    Relation of Anxiety, Depression, and Behavioral Problems With Time Allocated to Television, Computer, and Smartphone in Children Receiving Renal Replacement Therapy
    (2022) Taner, Hande Ayraler; Baskin, Esra; Kaya, Zulal Torenli; Sari, Burcu Akin; Taskiran, Candan; Akdur, Aydincan; Moray, Gokhan; Haberal, Mehmet; https://orcid.org/0000-0003-1428-0739; https://orcid.org/0000-0002-9730-7206; https://orcid.org/0000-0002-3462-7632; 35384817; AAK-7065-2021; S-3910-2019; AAJ-8097-2021
    Objectives: Children and adolescents with chronic diseases have more screen exposure time compared with their healthy peers. In this study, we investigated screen exposure time of children who received renal replacement therapy, which included kidney transplant and dialysis treatment, versus a healthy control group. Materials and Methods: Our study included 55 children and adolescents between the ages of 8 and 18 years. Although 28 participants did not have any chronic disease, 27 had chronic diseases and received renal replacement therapy. Among these patients, 17 had kidney transplant and 10 were receiving dialysis. A sociodemographic information form and the Conners Short-Form Parent Rating Scale were given to parents. Pediatric and adolescent patients completed the Children's Depression Inventory and Spielberger State-Trait Anxiety Scale-2. We analyzed differences between the groups with and without renal replacement therapy and examined relations between continuous variables. Results: Duration of television screen time was significantly higher in children and adolescents receiving renal replacement therapy. Patients in the renal replacement therapy group showed a positive correlation between the Conners Short-Form Parent Rating Scale anxiety subscores and duration of smartphone use. In the kidney transplant recipient group, smartphone and computer durations were positively correlated and television duration was negatively correlated with the Conners Short-Form Parent Rating Scale behavioral problems subscores. Conclusions: Children on renal replacement therapy may be at risk in terms of excessive television exposure. Children who are on dialysis and have had a kidney transplant may be more prone to the negative effects of screen exposure than healthy peers who do not have chronic illnesses. These children and adolescents should be closely monitored to avoid the negative effects of excessive screen exposure.

    Primary Focal Segmental Glomerulosclerosis Recurrence After Pediatric Renal Transplantation
    (2022) Baskin, Esra; Avci, Begum; Gulleroglu, Kaan; Akdur, Aydincan; Moray, Gokhan; Haberal, Mehmet; https://orcid.org/0000-0002-5375-379X; https://orcid.org/0000-0003-1434-3824; https://orcid.org/0000-0002-3462-7632; 35384808; GYU-5220-2022; AAJ-8833-2021; AAJ-8097-2021
    Objectives: Focal segmental glomerulosclerosis recurrence after renal transplant occurs frequently in pediatric patients and is associated with poor graft survival when patients reach adulthood. We investigated recurrence rates, recurrence risk factors, management strategies, and long-term graft function among pediatric renal transplant recipients with focal segmental glomerulosclerosis as primary disease. Materials and Methods: We retrospectively evaluated medical records of 34 pediatric patients with primary focal segmental glomerulosclerosis who had undergone renal transplant between 2004 and 2019 at our center. Focal segmental glomerulosclerosis recurrence was diagnosed by the presence of nephrotic range proteinuria after transplant and confirmed by graft biopsy. Preoperative prophylactic plasma exchange was administered to pediatric renal transplant recipients with primary focal segmental glomerulosclerosis. Plasma exchange was also used to treat focal segmental glomerulosclerosis recurrence, with rituximab added if the patient did not respond to plasma exchange. Results: All patients (male-to-female ratio of 19:15) in our group underwent renal transplant. Mean patient age at the time of transplant was 12.72 +/- 5.46 years. Twenty-nine patients received livingrelated donor allografts (85.3%) and 5 received organs from deceased donors (14.7%). We identified focal segmental glomerulosclerosis recurrence in 5 recipients (14.7%). Time from focal segmental glomerulosclerosis diagnosis to end-stage renal disease and duration of dialysis were shorter in the recurrence group than in the nonrecurrence group (48.4 months [range, 2-90 mo] vs 65.1 months [range, 8-123 mo] and 1.41 +/- 0.82 vs 3.18 +/- 1.88 years, respectively; P <.05). Donor type and transplant age were similar in both groups. Of those with recurrence who had received plasma exchange and rituximab, 3 patients (75%) had complete remission and 1 patient (25%) had partial remission. Conclusions: Prophylactic plasma exchange and the combined plasma exchange-rituximab regimen for treatment of focal segmental glomerulosclerosis recurrence resulted in low recurrence and good remission rates in our pediatric cohort.

    Vascular Complications After Renal Transplant: A Single-Center Experience
    (2017) Soy, Ebru H. Ayvazoglu; Akdur, Aydincan; Kirnap, Mahir; Boyvat, Fatih; Moray, Gokhan; Haberal, Mehmet; 0000-0002-8726-3369; 0000-0003-2498-7287; 0000-0002-0993-9917; 0000-0002-3462-7632; 28260440; AAA-3068-2021; AAH-9198-2019; AAE-1041-2021; F-4230-2011; AAC-5566-2019; AAJ-8097-2021
    Objectives: Despite surgical and medical advances, vascular complications are still among the major concerns after renal transplant, with a reported incidence of 3% to 15%. We evaluated the incidence and management of our transplant team's vascular complications over 40 years. Materials and Methods: From November 1975 to the present, we have performed a total of 2594 renal transplant procedures. Of these, 1997 grafts (76%) were obtained from living donors, and 597 grafts (24%) were obtained from deceased donors. All renal transplant procedures, including those performed in pediatric patients, used the extraperitoneal approach to the contralateral iliac fossa. Revascularization was performed for all grafts. A single end-to-end internal iliac artery anastomosis was performed in 1082 patients (41.8%), an end-to-side external iliac artery anastomosis was performed in 1289 patients (49.7%), and an end-to-side common iliac artery anastomosis was performed in 66 patients (2.5%). In 157 procedures (6%), there were at least 2 renal arteries, and both internal iliac arteries or external iliac arteries were used for anastomosis. Results: We observed 57 vascular complications (2.1%) in 54 renal transplant procedures. The most frequent complication was renal artery stenosis (n = 17; 0.6%). There were 8 instances of renal artery thrombosis (0.4%), 7 of renal artery kinking (0.3%), 5 of renal vein thrombosis (0.2%), 9 of renal vein kinking (0.5%), 3 of external iliac artery dissection (0.01%), 5 renal vein lacerations (0.2%), and 3 renal artery lacerations (0.01%). We performed urgent surgery for 41 vascular complications; 38 were managed successfully. Percutaneous interventional techniques were used successfully for 18 vascular complications. Conclusions: The vascular complication rate in our patients is lower than that reported in the literature. Surgical complications can be minimized with careful transplant technique and close follow-up, as early diagnosis is crucial to early management and successful treatment of complications.

    The New Anterior Less Invasive Crescentic Incision for Living Donor Nephrectomy
    (2020) Haberal, Mehmet; Soy, Ebru H. Ayvazoglu; Akdur, Aydincan; AlShalabi, Omar; Yildirim, Sedat; Moray, Gokhan; Torgay, Adnan; 0000-0002-8726-3369; 0000-0002-3462-7632; 0000-0002-5735-4315; 0000-0002-0993-9917; 0000-0002-6829-3300; 0000-0003-2498-7287; 33143599; AAA-3068-2021; AAJ-8097-2021; AAF-4610-2019; AAC-5566-2019; AAJ-5221-2021; AAE-1041-2021
    Objectives: Living-donor nephrectomy is a devoted procedure performed in a healthy individual; for these procedures, it is essential to complete the surgery with the lowest possible risk and morbidity and allow donors to regain their normal daily activity. To minimize anatomic and physiologic damage, we modified a surgical technique. Here, we report our experiences with the new anterior less invasive crescentic donor nephrectomy technique. Metarials and Methods: We retrospectively evaluated 728 donor nephrectomy patients who had the new anterior less invasive cresentic incision (n = 224), the classic open (n = 431), or the laparoscopic living-donor nephrectomy (n = 73) procedures. Demographic characteristics, preoperative and postoperative parameters, acute renal graft dysfunction, and firstyear graft and patient survival rates were compared between groups. Results: During the operation, the new cresentic incision living-donor nephrectomy allowed a safe and comfortable position for the patient and the anesthesiologist. Also, it procures safe access especially for grefts with multiple vessels. Patients had lower pain scores (P = .010), shorter hospital stays (2.25 vs 3.49 days) than those who received the classic open living-donor nephrectomy. Patients who received laparoscopic living-donor nephrectomy had significantly longer mean operation time (P = .016) and warm ischemia time (P <= .001) than those who had the new cresentic incision technique. All groups showed similar rates of first-year survival and delayed graft dysfunction. Conclusions: The new anterior less invasive cresentic incision open-donor nephrectomy approach is a safe, comfortable, effective, and less invasive modification of the living donor nephrectomy. Also, it procures safe access for grefts with multiple vessels.
