[PMID: 39064228 DOI: 10.3390/jcm13144188] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2024] [Revised: 07/13/2024] [Accepted: 07/16/2024] [Indexed: 07/28/2024] Open
Abstract
This pictorial essay aims to navigate through the complexities and challenges of renal transplantation (RT), by weaving together visual imagery with clinical insights within a comprehensive illustrative surgical guide. Herein, we provide a detailed visual exploration of the intricate anatomy and surgical processes necessary for both renal graft retrieval from the donor and also for an adequate implantation in the recipient. Regarding graft retrieval, after reviewing the relevant retroperitoneal surgical anatomy, and donor nephrectomy techniques, graft preservation and optimal backbench graft dissection principles were meticulously analyzed. Thereafter, the recipient surgical strategy for graft implantation was addressed, focusing on preoperative preparations, the site of implantation selection, exposure, operative bed dissection, graft revascularization, and urinary tract reconstruction. Careful donor and recipient selection, meticulous surgical execution, and rigorous postoperative management clearly hold a pivotal role in optimizing patient outcomes. Fostering a deeper understanding of the surgical nuances and clinical management practices that contribute to successful results post-RT, we hope to provide a useful practical tool for clinicians about to embark on the treacherous road of RT surgery. Innovative technologies and surgical practices that have already significantly improved the safety and effectiveness of RT stand testament to the importance of further scientific inquiry, conceptual developments, and clinical integration. Moving forward, it is essential that the medical community continues to refine these strategies and advocate for equitable access to transplantation, ensuring that advancements in the field translate into real-world benefits for all patients grappling with ESRD. The collaborative efforts of multidisciplinary teams are essential in addressing the complex clinical challenges associated with RT, with the ultimate goal of improving patient survival, enhancing graft longevity, and reducing healthcare disparities.

Abstract
INTRODUCTION Focal necrosis of the renal pelvis in a transplanted kidney is a rare but often morbid complication that may lead to graft loss. Given the scarcity of donor organs, all attempts are made to preserve the graft. Currently there is no standard surgical technique for reconstruction or repair of isolated renal pelvic necrosis. PRESENTATION OF CASE A 70-year-old male with end stage kidney disease underwent renal transplantation. The patient developed a day-three post-operative urine leak. During surgical exploration, a focal area of pelvic necrosis was observed without evidence of proximal or distal ureteric involvement. Given the excellent function of the renal allograft, a novel surgical technique was successfully used to repair the necrotic defect. Reconstruction of the renal pelvis was performed using an avascular rectus sheath patch. The patch was secured over the open pelvis following necrotic tissue debridement. The patient made a successful recovery with complete resolution of urine leak. A 6-week post-operative retrograde pyelogram confirmed no ongoing urine leak. DISCUSSION To restore anatomy, the pelvic defect was patched with avascular rectus sheath fascia. Advantages of this reconstructive method were technique simplicity and low donor site morbidity. Potential complications included patch failure with ongoing urine leak, ventral wall hernia through the fascial donor site and stenosis of the ureteropelvic junction. CONCLUSION This case highlights the successful surgical management of a renal pelvis urine leak patched with rectus sheath fascia. This technique could be considered as a graft saving procedure in similar cases where the alternative is transplant nephrectomy.

Abstract
Introduction: Urologic complications are thought to be the most common surgical complication of renal transplantation. Ureteral pathology, including stenosis, urine leak, and vesicoureteral reflux, predominates. Although endourologic and interventional radiological management may be utilized, failure rates remain relatively high and surgical reconstruction remains the definitive management. Robotic ureteral reconstruction has been demonstrated to provide patient benefit in nontransplant populations, but the literature on transplant reconstruction is very limited. This study reports an additional series of patients with a focus on surgical technique, as well as reviews the available evidence for robotic reconstruction for post-transplant ureteral complications. Methods: All institutional patients undergoing robotic-assisted reconstruction for post-transplant ureteral complications for the years 2019-2022 were included. Intra- and postoperative variables, patient demographics, and follow-up data were obtained retrospectively from parsing of patient records. Statistics were tabulated descriptively. Results: Eleven patients underwent ureteral reconstruction. Of the 11, 9 (81%) were male with a mean age of 51.9 years (16-70) and BMI of 33.8 (24.3-49.1). The most common (10/11) indication for reconstruction was stricture; the most common (10/11) technique used was Lich-Gregoir reimplantation. Mean operative time was 288 minutes (143-500). There were no intra- or immediate postoperative complications. Median length of stay was 2 days (1-22). There were two incidences of mortality at 2 and 5 months postoperatively unrelated to surgery. There were four readmissions within 30 days, three for urinary tract infection (UTI) and one for a pelvic abscess which required washout. The remainder of the cohort has been followed for a mean of 14.6 months (6-41) without any incidences of graft loss or recurrence of ureteral pathology. Conclusions: Robotic-assisted ureteral reconstruction is a technically challenging but highly feasible technique that may provide the benefits of minimally invasive surgery while still allowing definitive reconstruction. Centers with extensive robotic capabilities should consider the technique.

Abstract
Transplantation (KTx) is considered to be the best renal replacement therapy, and improving its outcomes remains a primary challenge. KTx ureteral stenting has been used to prevent urological complications, but there is no consensus on the timing of stent removal, and literature regarding routine ultrasonography after ureteric stent removal (RUSUS) to detect complications is lacking. Point-of-care ultrasound has been gaining drive in the medical community in recent years, including nephrologists. We aimed to define the incidence of urological complications diagnosed with RUSUS, if those findings changed patient's management and ultrasound utility. Contrary to previously published data, in our cohort RUSUS allowed a timely diagnosis and early treatment of urological complications, a key factor for successful transplantation. KTx point-of-care ultrasound is a cost-effective and reproducible test that provides relevant information to guide clinical decisions, seeming most efficient when performed approximately 2 weeks post ureteral stent removal. Interventional nephrologists can promptly perform these examinations, reducing waiting times and improving graft and patient's survival.

Abstract
OBJECTIVES Complications after kidney transplant can be divided into surgical and nonsurgical. Our study investigated the incidence of postoperative complications and types of complications in a single center. MATERIALS AND METHODS We retrospectively analyzed the occurrence of postoperative complications in 220 patients who underwent kidney transplantation at the Republican Scientific Center for Emergency Medical Care (Tashkent, Republic of Uzbekistan) from January 2019 to October 2022. RESULTS Among the 220 patients, various types of complications were observed in 42 cases (19.1%). Of these, 31 patients (73.8%) had surgical complications and 11 patients (26.2%) had nonsurgical complications. Surgical complications included hematoma of the postoperative wound in 8 patients (19.2%), thrombosis of the graft artery in 1 patient (2.4%), thrombosis of the venous anastomosis in 1 patient (2.4%), lymphocele of the postoperative wound in 7 patients (16.6%), wound infections 4 patients (9.5%), bleeding from the arterial anastomosis 2 patients (4.7%), bleeding from the venous anastomosis 1 patient (2.4%), kink of the venous anastomosis in 3 patients (7.2%), postoperative hernia in 2 patients (4.7%), and urological complications in the form of ureteral necrosis in 2 patients (4.7%). Nonsurgical complications included hyperacute rejection, which led to the removal of the graft, in 2 patients (4.8%), acute cellular rejection of the graft, which was successfully treated with methylprednisolone pulse therapy, in 4 patients (9.5%), delayed graft function in 1 patients (2.4%) case, and posttransplant diabetes mellitus in 4 patients (9.5%). CONCLUSIONS Despite the frequency of postoperative complications, timely assistance and further monitoring of patients can lead to normal functioning of the kidney transplant, except for cases of hyperacute rejection.

Abstract
OBJECTIVES We evaluated the feasibility, safety, and long-term outcomes of pyelovesicostomy as an alternative surgical treatment for complex ureteral lesions after kidney transplant. MATERIALS AND METHODS A single-center, retrospective, observational cohort study was conducted on 5 adult kidney transplant recipients who underwent pyelovesicostomy between January 2000 and June 2023. The collected data included patient demographics, surgery indication, time from transplant to pyelovesicostomy, procedure details, and kidney function at various time points after surgery. Primary outcomes were allograft function and complications. RESULTS The 5 patients (4 female, 1 male) had a mean age of 65.8 years and mean body mass index of 26.8. Indications were complex ureteral lesions. The time between transplant and reoperation ranged from 4 days to 12 years. Renal function improved for all patients, with a progressive decrease in mean serum creatinine concentration. The mean follow-up period extended to 7 years. One patient died with the graft still functional at 20 years after the operation, whereas the remaining 4 patients continue to live with functional grafts. CONCLUSIONS Our study suggests that pyelovesicostomy may provide a potent alternative for the management of complex ureteral lesions after kidney transplant. We have observed good short-term and long-term outcomes in specific patients, pointing toward a promising avenue oftreatment worth further exploration. This reaffirms the importance of a personalized approach in medicine, to consider each patient's unique conditions and characteristics during therapeutic decisions.

Abstract
BACKGROUND The optimal treatment for end-stage kidney disease is kidney transplantation. During the operation, a catheter is introduced into the bladder and remains in place postoperatively to allow the bladder to drain. This decreases tension from the cysto-ureteric anastomosis and promotes healing. Unfortunately, urinary catheters can pose an infection risk to patients as they allow bacteria into the bladder, potentially resulting in a urinary tract infection (UTI). The longer the catheter remains in place, the greater the risk of developing a UTI. There is no consensus approach to the time a catheter should remain in place post-transplant. Furthermore, the different timings of catheter removal are thought to be associated with different incidences of UTI and postoperative complications, such as anastomotic breakdown. OBJECTIVES This review aimed to compare patients who had their catheter removed < 5 days post-transplant surgery to those patients who had their catheter removed ≥ 5 days following their kidney transplant. Primary outcome measures between the two groups included: the incidence of symptomatic UTIs, the incidence of asymptomatic bacteriuria and the incidence of major urological complications requiring intervention and treatment. SEARCH METHODS We searched the Cochrane Kidney and Transplant Register of Studies up to 13 April 2023 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Registry Platform (ICTRP) Search Portal and ClinicalTrials.gov. SELECTION CRITERIA All randomised controlled trials (RCTs) and quasi-RCTs comparing timing of catheter removal post-transplantation were eligible for inclusion. All donor types were included, and all recipients were included regardless of age, demographics or type of urinary catheter used. DATA COLLECTION AND ANALYSIS Results from the literature search were screened by two authors to identify if they met our inclusion criteria. We designated removal of a urinary catheter before five days (120 hours) as an 'early removal' and anything later than this as a 'late removal.' The studies were assessed for quality using the risk of bias tool. The primary outcome of interest was the incidence of asymptomatic bacteriuria. Statistical analyses were performed using the random effects model, and results were expressed as relative risk (RR) with 95% confidence intervals (CI). Confidence in the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. MAIN RESULTS Two studies (197 patients) were included in our analysis. One study comprised a full-text article, and the other was a conference abstract with very limited information. The risk of bias in the included studies was generally either high or unclear. It is uncertain whether early versus late removal of the urinary catheter made any difference to the incidence of asymptomatic bacteriuria (RR 0.89, 95% Cl 0.17 to 4.57; participants = 197; I2 = 88%; very low certainty evidence). Data on other outcomes, such as the incidence of UTI and the incidence of major urological complications, were lacking. Furthermore, the follow-up of patients across the studies was short, with no patients being followed beyond one month. AUTHORS' CONCLUSIONS A high-quality, well-designed RCT is required to compare the effectiveness of early catheter removal versus late catheter removal in patients following a kidney transplant. At the present time, there is insufficient evidence to suggest any difference between early and late catheter removal post-transplant, and the studies investigating this were generally of poor quality.

Abstract
BACKGROUND In Latin America, few reports are available about the clinical outcomes of living donor kidney transplants (LDKT). We aim to evaluate the main clinical outcomes for LDKT patients in a single center's experience. METHODS We retrospectively evaluated 530 LDKT patients who underwent transplantation from August 2008 to December 2020 at Colombiana de Trasplantes. Graft survival censored for death and patient survival were determined up to 5 years post-transplantation by the Kaplan-Meier method. Vascular and urinary complications, readmission, and reintervention rates were documented. RESULTS A total of 530 LDKT patients were analyzed. Most of the recipients were men (56%). There were 123 patients (23.2%) with a preemptive transplant. Panel reactive antibody type I and II had higher immunologic risk (>20%) in 15.9% of the patients. The donor mean age was 37.8 ± 11.5 years. Most of the donors were women (52.6%) and related to the recipient (69.1%). Multivariate analysis identified panel reactive antibody type II (P = 0.003), female donor (P = 0.001), surgical reintervention at 30 days post-transplantation (P < .01), and delayed graft function (P < .01) as risk factors for graft loss. The graft survival death-censored rates were 93.7% and 89% at 1 and 5 years, respectively. Patient survival rates were 97.0% and 94.1% at 1 and 5 years after transplantation, respectively. CONCLUSIONS The long-term graft and patient survival rates in our center are comparable to previous reports from other leading centers. The clinical outcomes from a medium-sized center can be noteworthy, although not entirely new.

Abstract
Introduction The antiseptic skin preparation, bladder irrigation, corner-saving vascular anastomosis, DJ stenting, and extravesical ureteroneocystostomy (ABCDE) approach encompasses a range of modifications applied during different stages of the surgical procedure in renal transplantation. These modifications include the following: A, antiseptic skin preparation sequentially with cetrimide 3.35%, chlorhexidine scrub 4%, spirit, and povidone-iodine 10%; B, bladder irrigation with amikacin and betadine solution; C, corner-saving end-to-side vascular anastomosis; D, DJ stenting with early postoperative removal within three weeks; and E, extravesical ureteroneocystostomy using our institute's modified Lich-Gregoir technique. Methods This prospective observational study was conducted at our institution between March 2021 and May 2023. Data were collected from the patients' medical records and analyzed using Statistical Package for the Social Sciences (SPSS) (IBM SPSS Statistics, Armonk, NY, USA). Statistical tests, including t-test, Mann-Whitney test, chi-square test, and Fisher's exact test, were used for analysis. The study assessed various recipient, donor, intraoperative, and post-transplant factors, as well as surgical complications and stent-related factors. Results Out of 72 renal transplantations, 12 (16.6%) had the following surgical complications: urinary (n = 4; 5.5%), wound-related (n = 3; 4.1%), and lymphocele (n = 5; 6.9%). The most common complications were lymphocele (n = 5; 6.9%) and urinary leak (n = 4; 5.5%). Surgical complications were more common in male recipients (91.6% versus 8.3%), as well as in recipients with longer dialysis duration (24 ± 17 versus 11.0 ± 7 months) and had extended hospitalization time (16.4 ± 8.6 versus 8.0 ± 2.9 days) (p < 0.05). Wound infection correlated with longer surgeries (>300 minutes) and other complications. Lymphocele patients had higher drain output (>500 mL) on day 1 and longer hospital stays (>15 days). Urinary tract infections (UTIs) were linked to dialysis duration (>24 months), diabetes, and longer indwelling times of DJ stents and urinary catheters. Early DJ stent removal (<3 weeks) reduced UTI incidence and symptoms (p < 0.05). All complications were categorized as minor (3a or less), according to the Clavien-Dindo classification. Conclusion The modified ABCDE surgical approach in renal transplantation decreased the complications, showing favorable outcomes compared to those in the literature.

Abstract
BACKGROUND Kidney transplantations are increasing due to demographic changes and are the treatment of choice for end-stage renal disease. Non-vascular and vascular complications may occur in the early phase after transplantation and at later stages. Overall postoperative complications after renal transplantations occur in approximately 12 % to 25 % of renal transplant patients. In these cases, minimally invasive therapeutic interventions are essential to ensure long-term graft function. This review article focuses on the most critical vascular complications after renal transplantation and highlights current recommendations for interventional treatment. METHOD A literature search was performed in PubMed using the search terms "kidney transplantation", "complications", and "interventional treatment". Furthermore, the 2022 annual report of the German Foundation for Organ Donation and the EAU guidelines for kidney transplantation (European Association of Urology) were considered. RESULTS AND CONCLUSION Image-guided interventional techniques are favorable compared with surgical revision and should be used primarily for the treatment of vascular complications. The most common vascular complications after renal transplantation are arterial stenoses (3 %-12.5 %), followed by arterial and venous thromboses (0.1 %-8.2 %) and dissection (0.1 %). Less frequently, arteriovenous fistulas or pseudoaneurysms occur. In these cases, minimally invasive interventions show a low complication rate and good technical and clinical results. Diagnosis, treatment, and follow-up should be performed in an interdisciplinary approach at highly specialized centers to ensure the preservation of graft function. Surgical revision should be considered only after exhausting minimally invasive therapeutic strategies. KEY POINTS · Vascular complications after renal transplantation occur in 3 % to 15 % of patients.. · Image-guided interventional procedures should be performed primarily to treat vascular complications of renal transplantation.. · Minimally invasive interventions have a low complication rate with good technical and clinical outcomes..

Abstract
OBJECTIVES Some of the most common problems after kidney transplant are urologic complications, including ureterocystoanastomosis leakage and stenosis with the development of severe renal graft complications. Isolated plasma contains active substances that cause the activation of various growth factors for the processes of tissue repair or regeneration, has an anti- inflammatory effect, activates angiogenesis, and reduces the risk of infectious complications. Platelet-rich plasma is actively used to stimulate bone regeneration, heal wounds and ulcers on the skin, enhance reconstruction of the larynx and trachea, and ameliorate urethral damage, among other uses. This study was developed to evaluate the positive effect of platelet-rich plasma on the healing process of an anastomotic wound in a model of ureterocystoanas-tomosis in rats. MATERIAL AND METHODS We randomized 14 Wistar albino male rats into 2 groups: group 1 included 7 rats that received platelet-rich plasma after ureterocystostomy; group 2 was the control group and included 7 rats that underwent ureterocystostomy without platelet-rich plasma. On postoperative day 7, all animals were euthanized, and the anastomosis area was resected for determination of the tissue hydroxyproline levels and histopathology examination. RESULTS Tissue hydroxyproline levels were 767 ± 62.9 μg/g in group 1 and 256 ± 28.0 μg/g in group 2. Tissue hydroxyproline levels were significantly higher in group 1 compared with group 2 (P < .05). There were no significant differences in epithelial damage, acute inflammation, or fibrosis between the tissue samples of both groups. CONCLUSIONS The results of this study show that the use of platelet-rich plasma during ureterocystostomy produces a positive effect. Our further research will be devoted to the use of autologous platelet-rich plasma in ureterocystostomy in big models.

Abstract
Background and Purpose Kidney transplantation (KT) is the best therapy for chronic kidney disease (CKD). Major urologic complications (MUCs) are the second etiology associated to morbidity and graft loss following KT, after rejection episodes. The objective of this study was to estimate the incidence, risk factors and impact on graft survival associated to urological complications in KT patients. Patients and Methods A retrospective cohort based on electronic patient files of kidney transplant recipients from Colombiana de Trasplantes was created for the period August 2008 to September 2019. Initiation of follow-up was defined as the date of transplantation up to 3 years post-transplantation. Incidence of ureteral stenosis, ureteral obstruction, and ureteral leak was measured. A logistic regression multivariate model was adjusted to determine the associated factors to MUCs (yes/no). Patient and graft survival time were analyzed using a Kaplan-Meier method. Results A total of 1584 KT patients were included in the cohort. MUCs were present in 195 (12.6%) KT patients. We found that dialysis duration (OR: 1.004; p = 0.02) remained significant for the incidence of MUCs in KT patients of deceased donors. Probability of graft and patient survival at 3 years of follow-up was 90.5% and 85.5%, respectively. No significant difference was found on graft and patient survival in KT patients with or without MUCs. Conclusion MUCs are frequent complications for KT. We did not observe significant differences in graft or patient survival according to the presence of MUCs. The identification of MUCs and risk factors may guide transplant teams for future surgical and clinical decisions.

Abstract
Kidney transplant is the established treatment for patients with chronic kidney disease but is associated with complications due to the complexity of the procedure. Calyceal fistulas are rare urological complications in transplants caused by arterial occlusion with segmental infarction of the graft. Treatment is based on the extension of the affected area and the clinical status of the patient. For extensive infarctions treated surgically, a total nephrectomy of the transplanted kidney is generally performed. We present a case of a transplanted kidney with polar necrosis and calyceal fistula treated with partial nephrectomy of the affected area, maintaining the graft and preserving kidney function.

Abstract
OBJECTIVE Aim of our study was to test a noninvasive HSI technique as an intraoperative real time assessment tool for deceased donor kidney quality and function in human kidney allotransplantation. SUMMARY OF BACKGROUND DATA HSI is capable to deliver quantitative diagnostic information about tissue pathology, morphology, and composition, based on the spectral characteristics of the investigated tissue. Because tools for objective intraoperative graft viability and performance assessment are lacking, we applied this novel technique to human kidney transplantation. METHODS Hyperspectral images of distinct components of kidney allografts (parenchyma, ureter) were acquired 15 and 45 minutes after reperfusion and subsequently analyzed using specialized HSI acquisition software capable to compute oxygen saturation levels (StO2), near infrared perfusion indices (NIR), organ hemoglobin indices, and tissue water indices of explored tissues. RESULTS Seventeen kidney transplants were analyzed. Median recipient and donor age were 55 years. Cold ischemia time was 10.8 ± 4.1 hours and anastomosis time was 35 ± 7 minutes (mean ± standard deviation). Two patients (11.8%) developed delayed graft function (DGF). cold ischemia time was significantly longer (18.6 ± 1.6) in patients with DGF (P < 0.01). Kidneys with DGF furthermore displayed significant lower StO2 (P = 0.02) and NIR perfusion indices, 15 minutes after reperfusion (P < 0.01). Transplant ureters displayed a significant decrease of NIR perfusion with increased distance to the renal pelvis, identifying well and poor perfused segments. CONCLUSION Intraoperative HSI is feasible and meaningful to predict DGF in renal allografts. Furthermore, it can be utilized for image guided surgery, providing information about tissue oxygenation, perfusion, hemoglobin concentration, and water concentration, hence allowing intraoperative viability assessment of the kidney parenchyma and the ureter.

Abstract
Background Kidney transplantation is the most valuable renal replacement therapy. One of the most common urologic complications following kidney transplantation is ureter anastomosis leakage, which leads to high morbidity along with kidney graft loss. We hypothesized that indocyanine green (ICG) fluorescence videography can assess ureter perfusion after revascularization of transplanted kidneys. Methods We conducted a prospective cross-sectional study in end-stage renal disease patients who underwent deceased donor kidney transplantation at Ramathibodi Hospital from September 2019 to January 2020. The segments of transplanted ureters were categorized as having good or poor perfusion based on the percentage from ICG fluorescence videography images. Then the results from ICG fluorescence videography were compared with histopathology which is considered the gold standard. Results Thirty-one sections of dissected ureters were evaluated from 10 patients. Compared with pathological diagnosis of ureteral ischemia, ICG videography had sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and positive likelihood ratio of 100%, 92.6%, 66.7%, 100%, and 14, respectively. Accuracy was 93.6%. The area under the curve of ICG fluorescence videography was 0.96. The average ureter length that maintained good perfusion was 14 cm from the ureteropelvic junction. Adverse events from ICG were not observed in this study. Conclusions We conclude that ICG fluorescence videography is beneficial for detection of early ureteral ischemia in kidney transplantation patients, with negligible adverse events. However, further studies with larger numbers of patients are necessary to confirm our results and clinical outcomes regarding complication rates.

Abstract
A 52-year-old African-American male patient with end-stage renal disease due to hypertension underwent deceased donor kidney transplant procedure with no immediate complications. The postprocedure complications, interventions, and course were abstracted by chart review. The ureteric stent was removed with flexible cystoscopy on postoperative day (POD) 24. 24 hours later, the patient presented with abdominal pain and inability to urinate. An urgent ultrasound and noncontrast CT scan showed grade 4 hydronephrosis of the transplanted kidney. A percutaneous nephrostomy stent was placed for urinary diversion. A large ureteric hematoma filling the lumen of the mid to distal ureter was identified on the nephrostogram and was evacuated. A follow-up nephrostogram on POD 44 revealed a distal ureter stricture and persistent well-formed midureter filling defect. A repeat nephrostogram performed at POD 72 was done with stricture dilatation, internalization of stents, and removal of a percutaneous nephrostomy tube. The patient was maintained on antibiotics for UTI prophylaxis throughout the course.

Abstract
Urological problems in kidney transplant recipients are not limited only to posttransplantation urological complications. These problems are a cause of significant patient mortality and morbidity that have wide-ranging effects on graft survival throughout the entire life of the graft. Ultimately, the transplant comprises a major portion of the urinary system; therefore, the transplant team should be prepared for foreseeable and unforeseeable urological problems in the short and long terms. These mainly include postoperative urological complications (urine leakage, ureteral stenosis, and vesicoureteral reflux), bladder outlet obstruction, and graft urolithiasis. In recent years, significant advances have been made in the management of urological complications, especially due to advances in endourologic interventions. The aim of this review is to summarize the management of urological problems after kidney transplantation in the context of the current literature.

Abstract
Urologic complications can still occur following kidney transplantation, sometimes requiring multiple radiological and/or surgical procedures to fully correct the problem. Previously proposed extravesical ureteral reimplantation techniques still carry non-negligible risks of the patient developing urologic complications. About 10 years ago, a new set of modifications to the Lich-Gregoir technique was developed at our center, with the goal of further minimizing the occurrence of urologic complications, and without the need for initial ureteral stent placement. It was believed that an improvement in the surgical technique to minimize the risk of developing urologic complications was possible without the need for stent placement at the time of transplant. In this report, we describe the advantages of this technique (i.e., mobilized bladder, longer spatulation of the ureter, inclusion of bladder mucosa with detrusor muscle layer in the ureteral anastomosis, and use of a right angle clamp in the ureteral orifice to ensure that it does not become stenosed). We also retrospectively report our experience in using this technique among 500 consecutive (prospectively followed) kidney transplant recipients transplanted at our center since 2014. During the first 12mo post-transplant, only 1.4%(7/500) of patients developed a urologic complication; additionally, only 1.0%(5/500) required surgical repair of their original ureteroneocystostomy. Five patients(1.0%) developed a urinary leak, with 3/5 having distal ureteral necrosis, and 1/5 subsequently developing a ureteral stricture. Two other patients developed ureteral stenosis, one due to stricture and one due to ureteral stones. These overall results are excellent when compared with other reports in the literature, especially those in which routine stenting was performed. In summary, we believe that the advantages in using this modified extravesical ureteroneocystostomy technique clearly help in lowering the early post-transplant risk of developing urologic complications. Importantly, these results were achieved without the need for ureteral stent placement at the time of transplant.

Abstract
Transplant clinicians need to be watchful of several potential surgical complications in the early post-transplant period, including haemorrhage, extraperitoneal urine leak, and lymphocele. While haemorrhage and extraperitoneal urine leak usually present in the early post kidney transplant period, lymphoceles usually present 2–6 weeks after transplantation. While the colour and volume of the drained fluid can give some indication of the problem, is not enough evidence for a confident urine leak diagnosis. Further investigations, such as serum biochemical parameter analysis of the drained fluid and ultrasonography, help to identify the true cause. This paper discusses how to identify high-volume extraperitoneal urine leaks in the early post kidney transplant period and considers the differential diagnoses. Different ureteroneocystostomy procedures, including the Lich–Grégoir, Politano–Leadbetter, and U-stitch techniques, are discussed and compared regarding complication rates (especially urine leak and haematuria). The authors also address the management of low- and high-volume extraperitoneal urine leak, the follow-up needed, and the impact of urine leak on graft and patient survival, length of hospital stay, and rate of hospital readmission.

Effectiveness of Factor XIII Infusion in Treatment of Refractory Ureteral Leakage after Kidney Transplantation. Case Rep Transplant 2020; 2020:1780760. [PMID: 32724697 PMCID: PMC7381963 DOI: 10.1155/2020/1780760] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2020] [Revised: 06/19/2020] [Accepted: 07/03/2020] [Indexed: 11/17/2022] Open
Abstract
Despite the evolution of transplantation techniques, urological complications are common and result in loss of graft. We report the case of a 57-year-old man who developed continuous urine leakage despite pyeloureteral neoanastomosis and stenting after kidney transplantation from his dizygotic twin. Suspecting ureteral leakage, we performed pyeloureteral neoanastomosis using his native right ureter and a ureteral stent 5 days after the kidney transplant. However, urine leakage continued for several days. Because the plasma factor XIII level decreased to 48%, we administered factor XIII products (Fibrogammin P; CSL Behring, King of Prussia, PA) after the surgery. Although its utility and safety in patients with renal failure and/or transplantation are unclear, urine leakage stopped after the infusion of fibrogammin without any side effects. This is the first case report of the use of factor XIII for refractory urine leakage after kidney transplantation. Although further studies are needed, administration of factor XIII products could be one option for refractory urine leakage after transplantation.

Salter S, Lee A, Jaya J, Suh N, Yii MK, Saunder A. Timely surgical intervention for ureteric complications ensures adequate graft function in renal transplantation: a 10-year review. ANZ J Surg 2020; 90:1340-1346. [PMID: 32384207 DOI: 10.1111/ans.15914] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2019] [Revised: 03/20/2020] [Accepted: 04/06/2020] [Indexed: 11/29/2022]
Abstract
BACKGROUND Ureteric complications can cause significant morbidity in renal and simultaneous pancreas-kidney (SPK) transplantation. This 10-year review identified transplant patients with ureteric complications necessitating surgical intervention in an Australian tertiary centre. METHODS The hospital records were scrutinized in detail to identify all patients who underwent renal or SPK transplantation from 1 June 2009 to 31 May 2019 with subsequent surgical management of ureteric complications. A case series of patients with ureteric complications was generated and findings were analysed. RESULTS A total of 893 renal and SPK transplants were performed over the 10-year period. Ten of these (1.12%; seven renal and three SPK) had ureteric complications. All were managed surgically. Five of the 10 had ureteric leaks (0.56%); three had ureteric strictures (0.34%), one had ureteric obstruction from extraluminal compression (0.11%) and one had both leak and stricture (0.11%). All 10 patients underwent ureteric reimplantation. Two patients required more than one operation for their ureteric complication. No graft loss or surgical mortality occurred. All 10 patients currently have functioning kidney transplants and none require maintenance dialysis. CONCLUSION We report a low rate (1.12%) of ureteric complications in our renal and SPK transplants. Our standard practice of definitive correction by ureteric reimplantation is proving successful. The authors confirm that appropriate surgery is a viable and durable option in renal transplant patients with excellent graft outcomes.

Frailty predicts surgical complications after kidney transplantation. A propensity score matched study. PLoS One 2020; 15:e0229531. [PMID: 32102091 PMCID: PMC7043931 DOI: 10.1371/journal.pone.0229531] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2019] [Accepted: 02/07/2020] [Indexed: 12/27/2022] Open
Abstract
Background and objective Surgical complications after kidney transplantation can lead to catastrophic outcomes. Frailty has been associated with important kidney transplantation outcomes; however, there are no studies assessing this measure of physiological reserve as a specific predictor of surgical complications in this population. Such an assessment was, therefore, the objective of the present study. Methods A total of 87 individuals aged ≥ 18 years who underwent kidney transplantation between March 2017 and March 2018 were included. At the time of admission for kidney transplantation, demographic, clinical, and kidney transplantation data were collected, and the frailty score was calculated according to Fried et al., which comprises five components: shrinking, weakness, exhaustion, low activity, and slowed walking speed. Urological, vascular, and general surgical complications were assessed three months later, or until graft loss or death. The propensity score was used to achieve a better homogeneity of the sample, and new analyses were performed in this new, balanced sample. Results Of the 87 individuals included, 30 (34.5%) had surgical complications. After propensity score matching, the risk of surgical complications was significantly higher among the frail individuals (RR 2.14; 95% CI 1.01–4.54; p = 0.035); specifically, the risk of noninfectious surgical complications was significantly higher among these individuals (RR 2.50; 95% CI 1.11–5.62; p = 0.017). Conclusion The results showed that individuals with some degree of frailty before kidney transplantation were more subject to surgical complications. The calculation of the frailty score for transplant candidates and the implementations of measures to increase the physiological reserve of these patients at the time of kidney transplantation may possibly reduce the occurrence of surgical complications.

Abstract
<strong>BACKGROUND</strong> This study aimed to provide an update on the occurrence of early urological complications in living-donor and deceased-donor kidney transplantation (KTX). <strong>MATERIAL AND METHODS</strong> Data on all kidney transplant recipients in the Netherlands between January 2005 and December 2015 were retrieved from the prospectively collected Dutch National Organ Transplant Registry Database (NOTR). We assessed the incidence of major urological complications (MUCs) within 3 months after KTX, defined as urinary leakage and ureteral obstruction. Outcomes of living donor and deceased donor kidney transplants were compared. We performed regression analysis to identify predictive factors of urological complications and studied the influence of early urological complications on graft and patient survival. We performed an additional sub-study to explore the influence of preservation of the peri-ureteric connective tissue in living-donor KTX on the occurrence of urological complications. <strong>RESULTS</strong> Among 3329 kidney transplant recipients, urological complications occurred in 208 patients (6.2%) within 3 months after surgery. There were no significant differences in complication rates between recipients from living donors and deceased donors. Multiple regression analysis showed that older donor age and previous cardiac events of the recipient were predictors for the development of urological complications. Graft and patient survival were not affected by early MUCs. The additional sub-study showed that preservation of peri-ureteric tissue within living-donor KTX was not independently associated with urological complications. <strong>CONCLUSIONS</strong> Many living- and deceased-donor KTX recipients have early urological complications. MUCs did not affect long-term graft or patient survival.
