    Abstract Background and objective Graft performance is the most important postoperative parameter for patients undergoing kidney transplantation (KTx). The renal function of the donor is reported to be correlated with graft function after KTx. The body mass index (BMI) is also one of the important parameters involved in the prediction of graft function. The aim of this retrospective study was to examine the relationship between early postoperative graft function in patients undergoing KTx and donor cystatin C and estimated glomerular filtration rate (e-GFR) levels, graft weight/recipient BMI (G/B) ratio, and human leukocyte antigen (HLA) tissue compatibility. Materials and methods A total of 215 cases (215 donors, 215 recipients) who underwent KTx at our center between January 2018 and December 2022 were included in the study. Patients' age, sex, BMI, preoperative donor serum cystatin C and e-GFR levels, HLA tissue compatibility, graft weights, and recipient creatinine levels were recorded one week postoperatively. The Kolmogorov-Smirnov test and histogram plots were used to analyze the conformity of the variables to the normal distribution and Spearman's correlation test was used to analyze the relationship between variables. Results A negative correlation was identified between recipient creatinine level and G/B ratio and donor e-GFR (r = -0.256 and -0.137, respectively). Donor cystatin C level showed a positive correlation with recipient creatinine level (r = 0.242). No significant correlation was noted in terms of tissue matching rates (p = 0.616). Conclusion Although these three parameters are correlated with early graft functions, the graft weight/recipient BMI ratio has the strongest correlation.

    Abstract Background: Post-transplant lymphocele is a common complication with a potentially severe course and may require percutaneous drainage or open/percutaneous surgical intervention. Closure of the lymphatics around the iliac vessels is paramount in avoiding lymphocele formation. This study aimed to evaluate the effectiveness of bipolar electrocautery-based vascular sealers (BSD) in the dissection and/or ligation of lymphatic vessels in terms of the development of lymphoceles and postoperative kidney functions in live donor kidney transplants at our center.
    Methods: A total of 63 patients who underwent kidney transplantation (KTx) between January and December 2021 were included in the study. Data, including postoperative creatinine values and postoperative ultrasonography follow-up, were recorded. Thirty-seven patients who were operated on using conventional ligation for iliac vessel preparation were included in group 1. Twenty-six patients treated using BSD for iliac vessel preparation were included in group 2. Statistical analysis was performed to compare these groups. This study complied with The Helsinki Congress and The Declaration of Istanbul.
    Results: There was no significant difference between the groups in terms of postoperative first-week creatinine values (1.176 mg/dL vs 1.203 mg/dL), first-month creatinine values (1.061 mg/dL vs 1.091 mg/dL), first-week collection volume (33.240 mL vs 33.430 mL), and third-month collection volume (23.120 mL vs 23.430 mL) (P > .05).
    Conclusions: In KTx surgery, BSD is as safe as and faster than conventional ligation in preparation of the recipient's iliac vessels.

    Abstract Background: Kidney transplantation can be performed with different surgical approaches, such as conventional open kidney transplantation (CKT), minimally invasive kidney transplantation (MIKT), laparoscopic kidney transplantation, and robot-assisted kidney transplantation. Conventional open kidney transplantation is usually performed using a Gibson or hockey stick incision, may be associated with higher wound complication rates, and results in worse cosmetic outcomes compared with minimally invasive methods. Minimally invasive kidney transplantation is performed with a smaller skin incision than CKT but may result in limited surgical exposure. This study aimed to compare the surgical results of MIKT and CKT.
    Methods: Fifty-nine patients with a body mass index of 22 kg/m
    Results: The mean incision length was calculated as 12.7 cm in group 1 and 7.3 cm in group 2 (P < .05). There was no statistically significant difference between the groups in terms of lodge preparation time, vein clamp time, artery clamp time, ureteroneocystostomy time, visual analog scale scores, postoperative creatinine levels, or complication rates (P > .05 for each comparison).
    Conclusions: Without compromising the goals and primary concerns of transplantation surgery, MIKT can be offered to selected transplant patients with cosmetic concerns.

    Abstract Background Non-compliance with immunosuppressive drugs has been reported as the most significant cause of graft loss. Since non-compliance with immunosuppressive drugs is preventable, certain approaches based on the risk factors and causes of non-compliance can help eliminate this problem. Aims The purpose of this study is to assess the effectiveness of patient education and interviews in improving medication adherence of renal-transplant recipients. Materials and methods This study was designed as a randomized controlled trial. Using the G*Power program, the sample size was calculated as 60 subjects, with 30 in both the intervention group and control group. Data collection tools included a patient information form, a pretest-posttest, a drug monitoring form for kidney transplant patients, the Immunosuppressive Therapy Adherence Scale, measurement of tacrolimus blood levels, and a training booklet.  Results The mean knowledge score in the intervention group was 12.17±3.39 at baseline, and it increased to 20.73±1.57 after the intervention. The mean scores on the Immunosuppressant Therapy Adherence Scale were 11.67±0.55 and 10.70±0.99 in the intervention group and control group, respectively. There was a statistically significant difference between the pre-test and post-test means on the Immunosuppressant Therapy Adherence Scale in the intervention group. The mean Immunosuppressant Therapy Adherence Scale score was higher in the intervention group. In the measurement of tacrolimus blood levels, medication adherence was found the be higher in the intervention group. The difference between the groups was statistically significant. There was a positive correlation between the tacrolimus blood levels and the Immunosuppressant Therapy Adherence Scale scores in both groups. Conclusions To conclude, our results have demonstrated that patient education and interviews improve immunosuppressant medication adherence in renal transplant recipients. Using direct or indirect methods proved similar outcomes, suggesting that both evaluation methods are safe.

    Abstract Background: To evaluate hand-assisted laparoscopic donor nephrectomy (HALDN) in terms of intraoperative and postoperative results.
    Methods: After institutional review board approval was obtained, a total of 1864 HALDN operations performed between March 2007 and January 2022 were retrospectively analyzed. Age, sex, body mass index (BMI), status of smoking and presence of previous abdominal surgery, laterality, operative time, transfusion requirement, port counts, length of extraction incision, time until mobilization, time until oral intake, donor serum creatinine levels before and one week after the surgery, length of postoperative hospital stay, intraoperative complications, and postoperative recovery and complications were recorded and statistically analyzed. Multiple renal arteries, BMI, right nephrectomy and male sex were also separately evaluated as risk factors for complications and operative time.
    Results: A total of 825 (44.26%) male and 1039 (55.74%) female patients were enrolled in the study. The mean age of the patients was 45.79 ± 12.88 years. There were a total of 143 complications (7.67% of the total 1864 cases) consisting of 68 (3.65%) intraoperative and 75 (4.02%) postoperative complications. Open conversion was necessary for 10 patients (0.53%) to manage intraoperative complications. Reoperation was needed for 1 patient due to bleeding 6 h after the operation. Multiple renal arteries were a risk factor for intraoperative complications and prolonged operative time. Right nephrectomy and male sex were also related with longer operative times.
    Discussion: HALDN is a safe procedure associated with low complication rates.

    Abstract Urinary tract infection is the most common infectious complication following kidney transplant. Anatomic abnormalities, bladder dysfunction, a positive history of febrile urinary tract infection, and recipient age are reported risk factors. The aim of this study was to determine the risk factors for fUTI, which necessitated hospitalization in the first year after renal transplantation in our pediatric transplant population. A retrospective review of 195 pediatric patients who underwent kidney transplant between 2008 and 2017 from a single institution was performed. All patients admitted to the hospital with fUTI were marked for further analyses. The risk factors including age, gender, dialysis type, history of urologic disorders, and preoperative proteinuria for fUTI in the first year after kidney transplantation and graft survivals were investigated. Independent-sample t test and chi-square tests were used for univariate analysis. Exhaustive CHAID algorithm was used for multivariate analysis. The data of 115 male and 80 female patients were retracted. The mean ages of our cohort for males and females were 9.5 ± 5.1 and 10 ± 4.8 years, respectively. The age of the patients at transplant and their gender were found to be a statistically significant risk factors for developing fUTIs. Multivariate analysis showed that fUTI was common in female patients and a subgroup of male patients who had preoperative proteinuria, but no neurogenic bladder had higher risk compared with male patients without proteinuria. Patient surveillance and antibiotic prophylaxis algorithms can be developed to prevent febrile urinary tract infections seen after pediatric kidney transplantation in risky population.

    Abstract Objective: To determine the incidence of adrenal incidentalomas (AIs) in a single-center series of living renal donors, to describe an evaluation algorithm for AIs in this patient population, and to compare the complication rates of hand-assisted laparoscopic donor nephrectomy (HALDN) with those of combined HALDN and adrenalectomy.
    Methods: We performed a single-center, retrospective study of consecutive living kidney donors who underwent laparoscopic nephrectomy for transplantation, with or without simultaneous ipsilateral adrenalectomy, between January 2008 and September 2014.
    Results: During the study period, AIs were detected in 18 of 1033 potential living renal donors who underwent computerized tomographic angiography. Application of additional donor selection criteria and of an adrenal mass assessment algorithm resulted in 849 HALDN, of which 13 were combined with simultaneous adrenalectomy. The hospital length of stay (2.4 vs 2.6 days), perioperative (0.025 vs 0.077), early (0.073 vs 0.077), and late (0.014 vs 0.077) postoperative complication rates, and conversion to open donor nephrectomy (0.008 vs 0.00) were not significantly different. Mean operative time was significantly longer in the adrenalectomy group. None of the adrenal masses were malignant.
    Conclusion: Here, we presented our algorithm to manage the living kidney donors with AIs. Although donor population with AIs was relatively small in number, simultaneous adrenalectomy and ipsilateral nephrectomy seemed to be technically safe and conferred no identifiable increased risk of malignancy for the kidney transplant donor, when the incidentaloma is nonfunctional and less than or equal to 4 cm as assessed by preoperative imaging.

    Abstract Background: Currently, multidetector computed tomographic (MDCT) angiography has become a noninvasive alternative imaging modality to catheter renal angiography for the evaluation of renal vascular anatomy in living renal donors. In this study, we investigated the diagnostic accuracy of 16-slice MDCT in the preoperative assessment of living renal donors.
    Methods: Fifty-nine consecutive living renal donors (32 men, 27 women) underwent MDCT angiography followed by open donor nephrectomy. All MDCT studies were performed by using a 16-slice MDCT scanner with the same protocol consisting of arterial and nephrographic phases followed by conventional abdominal radiography. The MDCT images were assessed retrospectively for the number and branching pattern of the renal arteries and for the number and presence of major or minor variants of the renal veins. The results were compared with open surgical results.
    Results: The sensitivity and specificity of MDCT for the detection of anatomic variants of renal arteries including the accessory arteries (n = 9), early arterial branching (n = 7) and major renal venous anomalies including the accessory renal veins (n = 3), late venous confluence (n = 4), circumaortic (n = 2) or retroaortic (n = 3) left renal veins were 100%. However, the sensitivity for identification of minor venous variants was 79%. All of three ureteral duplications were correctly identified at excretory phase conventional abdominal radiography.
    Conclusion: Sixteen-slice MDCT is highly accurate for the identification of anatomic variants of renal arteries and veins. Dual-phase MDCT angiography including arterial and nephrographic phases followed by conventional abdominal radiography enables complete assessment of renal donors without significant increase of radiation dose. However, the evaluation of minor venous variants may be problematic because of their small diameters and poor opacification.
