Abstract
INTRODUCTION The protocol for deceased donor kidney transplants has been standardised. The procedure for a living donor has peculiarities derived from the differences in the graft. When a living kidney donor program is implemented, changes occur in both the profile of the kidney transplant candidate and in the postoperative treatments. AIMS To discover whether a living donor program influences the functional outcomes of kidney grafts in a longstanding classical deceased donor kidney transplant program and to identify the factors associated with transplant outcomes. METHODS Retrospective observational multicentre study. SAMPLE Kidney transplant patients in two urology referral centres for renal transplant in Spain between 1994 and 2019. Groups: TV (living transplant): patients given kidney transplants from living donors (n = 150); TCpre11 (deceased transplant previous to 2011): patients given kidney transplants from deceased donors before the living donor program was implemented (n = 650); and TCpost11 (deceased transplant after 2011): patients given kidney transplants from deceased donors after the living donor program was implemented (n = 500). RESULTS Mean age was 55.75 years (18-80 years), higher in TCpre11. There were 493 female patients (37.92%) and 1007 male patients (62.08%). Mean body mass index (BMI) was 26.69 kg/m2 (17.50-42.78 kg/m2), higher in TCpre11. Mean ischemia time was 17.97 h (6-29 h), higher in TCpost11. Median duration of urethral catheter: 8 days (6-98 days), higher in TCpost11. Median duration of double-J ureteral stent: 58 days (24-180 days), higher in TCpost11. Pretransplant UTIs: 17.77%, higher in TCpre11 (25.69%) than in TV (12%), higher in TV (12%) than TCpost11 (9.2%), and higher in TCpre11 (25.69%) than TCpost11 (9.2%). Acute renal rejection in 9.33% of TV, 14.77% of TCpre11, and 9.8% of TCpost11. Multivariate analysis: TCpost11 featured higher BMI, more smoking, and chronic renal failure progression time. Lower use of nonantibiotic prophylaxis to prevent recurrent urinary tract infections, increased duration of urethral catheters due to obstructive problems, and favoured deterioration of kidney function was observed in the deceased donor program. The living donor (LD) program had a strong influence on deceased donor transplants in the prelysis phase. Implementation of a LD program was associated with a decrease in the likelihood of acute rejection in TCpost11 and an increase in the tendency towards normal kidney function. CONCLUSIONS Implementing living donor transplant programs affects functional outcomes in deceased donor transplants, reducing the probability of acute rejection and increasing the tendency towards normal kidney function. Preventing recurrent urinary tract infections with measures other than antibiotics, smoking cessation, delaying the removal of the double-J stent from the graft, and pre-emptive transplant (transplant prior to dialysis) are associated with improved renal function of the graft.

External ureteric stent versus internal double J stent in kidney transplantation: a retrospective analysis on the incidence of urological complications and urinary tract infections. FRONTIERS IN NEPHROLOGY 2023; 3:1130672. [PMID: 37675367 PMCID: PMC10479681 DOI: 10.3389/fneph.2023.1130672] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Accepted: 04/13/2023] [Indexed: 09/08/2023]
Abstract
Introduction Urologic complications (UCs) and urinary tract infections (UTIs) are common after kidney transplantation. Intraoperative stent placement at the vesicoureteric anastomosis reduces UC risk, but increases UTI risk. Methods In 2014 our stenting protocol changed from external ureteric stent (ES) to internal double J stent (DJ). We retrospectively studied the occurrence of UCs and UTIs in relation to ES or DJ in 697 kidney recipients. Methods An ES was used in 403 patients (57.8%), in 294 (42.2%) a DJ. ES was removed 7-12 days and DJ 3-4 weeks post-operative. Induction immunosuppression was the same in both groups. Primary outcomes at 6 months follow-up were UC (urinary leakage/ureter stenosis) and UTI; they were related to stenting procedure and clinical and transplant characteristics. The incidence of UCs was similar for ES (8.4%) and DJ (6.8%), p=0.389. ES use was a significant risk factor for UTI (OR 1.69 (1.15-2.50), p=0.008). Post-transplant hospitalization was significantly shorter in the DJ group. Despite more acute rejection episodes with ES (ES/DJ: 16.4%/6.1%, p<0.001), no clinical relevant differences in graft outcomes existed. Discussion A DJ is, compared to ES, associated with a lower incidence of UTIs and comparable occurrence of UCs and is therefore the preferred technique for stenting the vesicoureteric anastomosis.

[PMID: 36168725 DOI: 10.1093/bjs/znac325] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2022] [Revised: 08/01/2022] [Accepted: 08/22/2022] [Indexed: 12/31/2022]
Abstract
BACKGROUND Enhanced Recovery After Surgery (ERAS) protocols are now widely practiced in major surgery, improving postsurgical outcomes. Uptake of these programmes have been slow in kidney transplantation due to challenges in evaluating their safety and efficacy in this high-risk cohort. To date, there are no unified guidance and protocols specific to ERAS in kidney transplantation surgery. This paper aims to summarise current evidence in the literature and develop ERAS protocol recommendations for kidney transplantation recipients. METHODS PubMed, Cochrane, Embase and Medline databases were screened for studies relevant to ERAS protocols in kidney transplantation, up to August 2021. A secondary search was repeated for each ERAS recommendation to explore the specific evidence base available for each section of the protocol. Randomised controlled trials, case-control and cohort studies were included. The Grading of Recommendations, Assessment, Development and Evaluations (GRADE) framework was used to evaluate the quality of evidence available and recommendations. RESULTS We identified six eligible studies with a total of 1225 participants. All studies found a reduction in length of hospital stay without affecting readmission rates. The evidence behind specific pre-operative, intra-operative and post-operative interventions included in current ERAS protocols are reviewed and discussed. CONCLUSION Compared to other surgical specialties, the evidence base for ERAS in kidney transplantation remains lacking, with further room for research and development. However, significant improvements to patient outcomes are already possible with application of the currently available evidence. This has shown that ERAS in kidney transplantation surgery is safe and feasible, with improved postoperative outcomes.

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
Lay Summary
During a kidney transplant, a plastic tube (stent) is placed in the ureter, connecting the new kidney to the bladder, in order to keep the new join open during the initial phase of transplantation. The stent is then removed after a few weeks via a camera procedure (cystoscopy), as it is no longer needed. The present study compared performing this in the operating theatre or in clinic for transplanted patients using a new single-use type of camera with an integrated grasper system. The results have shown that it is safe and cost-effective to do this in clinic, despite patients being susceptible to infection after transplantation.

Association Between the Placement of a Double-J Catheter and the Risk of Urinary Tract Infection in Renal Transplantation Recipients: A Retrospective Cohort Study of 1038 Patients. Transplant Proc 2021; 53:1927-1932. [PMID: 34229904 DOI: 10.1016/j.transproceed.2021.05.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Revised: 04/11/2021] [Accepted: 05/04/2021] [Indexed: 12/17/2022]
Abstract
BACKGROUND The incidence of urinary complications in transplantation is 2% to 20%, which can be decreased with the use of a double-J catheter. The objective of this study was to determine the association between the use of the catheter and the probability of urinary tract infection (UTI). METHODS We studied a retrospective cohort of 1038 patients divided into 2 groups: those treated with vs without a double-J catheter. Perioperative factors related to catheter use were analyzed. Second, whether the use of the catheter was associated with fewer other urinary complications was analyzed. RESULTS Of the whole sample, 72 patients were eliminated from the study, and 358 (37%) received a double-J catheter. UTIs occurred in 190 patients (19.6%), of whom a greater proportion received a catheter: 88 of 358 (24.6%) vs 102 of 608 (16.8%) (odds ratio, 1.61; 95% confidence interval, 1.17-2.22; P = .003). CONCLUSIONS The placement of a double-J catheter during transplant is associated with a higher proportion of UTIs, increasing their severity and the cost of care, without having a clear effect on other types of urinary complications.

The Impact of Timing of Stent Removal on the Incidence of UTI, Recurrence, Symptomatology, Resistance, and Hospitalization in Renal Transplant Recipients. J Transplant 2021; 2021:3428260.

Abstract
Purpose To evaluate the impact of early (<3 weeks) versus late (>3 weeks) urinary stent removal on urinary tract infections (UTIs) post renal transplantation. Methods A retrospective study was performed including all adult renal transplants who were transplanted between January 2017 and May 2020 with a minimum of 6-month follow-up at King Abdulaziz Medical City, Riyadh, Saudi Arabia. Results A total of 279 kidney recipients included in the study were stratified into 114 in the early stent removal group (ESR) and 165 in the late stent removal group (LSR). Mean age was 43.4 ± 15.8; women: n: 114, 40.90%; and deceased donor transplant: n: 55, 19.70%. Mean stent removal time was 35.3 ± 28.0 days posttransplant (14.1 ± 4.6 days in the ESR versus 49.9 ± 28.1 days in LSR, p < 0.001). Seventy-four UTIs were diagnosed while the stents were in vivo or up to two weeks after the stent removal “UTIs related to the stent” (n = 20, 17.5% in ESR versus n = 54, 32.7% in LSR; p=0.006). By six months after transplantation, there were 97 UTIs (n = 36, 31.6% UTIs in ESR versus n = 61, 37% in LSR; p=0.373). Compared with UTIs diagnosed after stent removal, UTIs diagnosed while the stent was still in vivo tended to be complicated (17.9% versus 4.9%, p: 0.019), recurrent (66.1% versus 46.3%; p: 0.063), associated with bacteremia (10.7% versus 0%; p: 0.019), and requiring hospitalization (61% versus 24%, p: 0.024). Early stent removal decreased the need for expedited stent removal due to UTI reasons (rate of UTIs before stent removal) (n = 11, 9% in the early group versus n = 45, 27% in the late group; p=0.001). The effect on the rate of multidrug-resistant organisms (MDRO) was less clear (33% versus 47%, p: 0.205). Early stent removal was associated with a statistically significant reduction in the incidence of UTIs related to the stent (HR = 0.505, 95% CI: 0.302-0.844, p=0.009) without increasing the incidence of urological complications. Removing the stent before 21 days posttransplantation decreased UTIs related to stent (aOR: 0.403, CI: 0.218-0.744). Removing the stent before 14 days may even further decrease the risk of UTIs (aOR: 0.311, CI: 0.035- 2.726). Conclusion Early ureteric stent removal defined as less than 21 days post renal transplantation reduced the incidence of UTIs related to stent without increasing the incidence of urological complications. UTIs occurring while the ureteric stent still in vivo were notably associated with bacteremia and hospitalization. A randomized trial will be required to further determine the best timing for stent removal.

Abstract
Background The most common infections among renal transplant patients are urinary tract infections (UTI). Our main objective in this study is to determine the incidence of UTIs in patients who have undergone renal transplantation in our hospital, to identify the causative microbiological agents, risk factors and determine the effects of UTI on short-term graft survival. Methods Urinary tract infections, which developed within the first year of renal transplantation, were investigated. Patients were compared regarding demographic, clinical, laboratory characteristics and graft survival. Results 102 patients were included in our study. Fifty-three patients (53%) were male and 49 (48%) were female. Sixty-seven urinary tract infection attacks in 21 patients (20.5%) were recorded. Age (p = 0.004; 95% Confidence Interval [CI]: 1.032–1.184), longer indwelling urinary catheter stay time (p = 0.039; 95% Confidence Interval [CI]: 1.013–1.661) and urologic complications (p = 0.006; 95% Confidence Interval [CI]: 0.001–0.320) were found as risk factors for UTI development in the first year of transplantation. Escherichia coli and Klebsiella pneumoniae were the most frequently isolated microorganisms. Of these bacteria, 63.2% were found to be extended spectrum beta lactamase (ESBL) positive. Multidrug resistant microorganisms (MDROs) were more frequent in male patients (32 episodes in males vs. 14 episodes in females, p = <0.001). UTI had no negative impact on short-term graft survival. Conclusion Our study results represent the high incidence of UTI with MDROs in KT recipients. Infection control methods should be applied even more vigorously especially in male transplant patients since a higher incidence of UTI caused by resistant microorganisms was reported in male patients.

Transplant Proc 2020; 52:2403-2408. [PMID: 32482447 DOI: 10.1016/j.transproceed.2020.03.033] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2020] [Revised: 03/10/2020] [Accepted: 03/30/2020] [Indexed: 11/28/2022]
Abstract
BACKGROUND Urinary tract infection (UTI) occurs in 21% of kidney recipients within the first 3 months after transplantation (KTx). It is associated with impaired graft function. Ureteral stent placement increases the occurrence of UTIs. The aim of this study was to assess the correlation between double-J placement, UTI incidence, and graft function. MATERIAL AND METHODS We conducted an observational study in 753 patients transplanted between 2010 and 2017 in compliance with the Helsinki Congress and the Istanbul Declaration. Recipients with preserved graft function at the 1-year follow-up were included. Medical records were searched for intraoperative double-J placement, UTI incidence, and estimated glomerular filtration rate (eGFR) on the 30th and 360th days post-transplant. Pretransplant hypothetical estimated GFR (heGFR) of each donor was calculated from donors' age and physiological age-dependent loss of functional nephrons. Spearman's correlation and linear regression analyses were applied. P < .05 was considered significant. RESULTS UTIs occurred in 239 (31.8%) patients. On the 30th day after KTx, eGFR was significantly lower in the UTI group (median, 39.5 vs 43.2; P < .01). A similar pattern was seen 1 year after KTx (47.5 vs 54.2; P < .01). Urinary stents were placed in 213 (28.3%) patients. UTIs occurred in 92 (43.2%) of them and in 147 (27.2%) of nonstented patients (odds ratio: 2; 95% confidence interval [CI], 1.5-2.8; P < .01). Median donor heGFR was 105.8 mL/min/1.73 m2, whereas median donor Modification of Diet in Renal Disease (MDRD) GFR was 64.2 mL/min/1.73 m2. A moderate correlation between age-adjusted heGFR and 1-year transplant function (r = .47) was noted. CONCLUSIONS UTIs in the early post-transplant period decreased 1-year eGFR by 4 to 5 mL/min/1.73 m2. UTIs occurred twice as often when a urinary stent was placed.

Double J stent is superior to externally draining ureteric stent in enhancing recovery after kidney transplantation - A prospective cohort study. Int J Surg 2019; 71:175-181. [PMID: 31600570 DOI: 10.1016/j.ijsu.2019.09.031] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2019] [Revised: 09/15/2019] [Accepted: 09/27/2019] [Indexed: 11/16/2022]
Abstract
BACKGROUND Routine intraoperative ureteric stenting lowers the rate of urological complications after kidney transplantation. However, there is no consensus about the optimal stent design and duration. The aim of this prospective cohort study was to compare the influence of double J (JJ) stents and externally draining percutaneous (PC) stents on the early quality of recovery after living donor kidney transplantation. MATERIALS AND METHODS A prospective cohort study was performed in two consecutive cohorts of 40 patients who underwent living donor kidney transplantation at the Radboud university medical center between April 2016 and October 2017. The first cohort of 40 patients received a 6-French externally draining PC stent. The second cohort of 40 patients received a 6-French/14 cm JJ stent. We compared the influence of the stent design on the quality of early post-operative recovery (measured by the Quality of Recovery-40 questionnaire) and the length of hospital stay. RESULTS Patients with a JJ stent scored significantly better on the Quality of Recovery score on the third and fifth postoperative day, when compared to patients with a PC stent. Furthermore, in comparison to patients with a PC stent, patients with a JJ stent were earlier mobilising and independent in daily activities, resulting in a shorter length of hospital stay. The number of postoperative urological complications was comparable between the two groups. CONCLUSION The use of JJ stents during living donor kidney transplantations improves the postoperative recovery and shortens the length of hospital stay, when compared to PC stents without compromising the number of postoperative urological complications.
