Background. Ureteric stent insertion during kidney transplantation reduces the incidence of major urological complications (MUCs). We evaluated whether routine poststent removal graft ultrasonography (PSRGU) was useful in detecting MUCs before they became clinically or biochemically apparent.Methods. A retrospective analysis was undertaken of clinical outcomes following elective stent removals from adult single renal transplant recipients (sRTRs) at our centre between 1 January 2011 and 31 December 2013.Results. Elective stent removal was performed for 338 sRTRs. Of these patients, 222 had routine PSRGU (median (IQR) days after stent removal = 18 (11–31)), 79 had urgent PSRGU due to clinical or biochemical indications, 12 had CT imaging, and 25 had no further renal imaging. Of the 222 sRTRs who underwent routine PSRGU, 210 (94.6%) had no change of management, three (1.4%) required repeat imaging only, and eight patients (3.6%) had incidental (nonureteric) findings. One patient (0.5%) had nephrostomy insertion as a result of routine PSRGU findings, but no ureteric stenosis was identified. Of 79 patients having urgent PSRGU after elective stent removal, three patients required transplant ureteric reimplantation.Conclusions. This analysis found no evidence that routine PSRGU at two to three weeks after elective stent removal provides any added value beyond standard clinical and biochemical monitoring.

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 Ureteric stricture is a common and salvaging complications after renal transplantation. Two treatment methods are usually used, retrograde ureteral stent placement and percutaneous nephrostomy. The former has a higher failure rate, the latter has a great risk. Therefore, a safe and reliable treatment is needed. Case presentation A technique of retrograde insertion of ureteral stent was established, which was applicable in three transplant recipients with post-transplant ureteral stenosis, and the data was retrospectively recorded. The patients are 2 men and 1 woman, ages 44, 27 and 32 years. These patients underwent a total of five times of retrograde insertion of ureteral stent between 2018 and 2019. None of these patients had any postoperative complication, but all patients had complete recovery from oliguric status within two weeks. Conclusions The retrograde ureteric stent insertion by percutaneous suprapubic access to the bladder (RUS-PSAB) was demonstrated feasibility and safety in a case series with short-term follow-up. However, larger prospective studies are needed.

Implanting a ureteric stent during ureteroneocystostomy reduces the risk of leakage and ureteral stenosis after kidney transplantation (KTx), but it may also predispose to urinary tract infections (UTIs). The aim of this study is to determine the optimal timing for ureteric stent removal after KTx. Searches were performed in EMBASE, MEDLINE Ovid, Cochrane CENTRAL, Web of Science, and Google Scholar (until November 2017). For this systematic review, all aspects of the Cochrane Handbook for Interventional Systematic Reviews were followed and it was written based on the PRISMA-statement. Articles discussing JJ-stents (double-J stents) and their time of removal in relation to outcomes, UTIs, urinary leakage, ureteral stenosis or reintervention were included. One-thousand-and-forty-three articles were identified, of which fourteen articles (three randomised controlled trials, nine retrospective cohort studies, and two prospective cohort studies) were included (describing in total n = 3612 patients). Meta-analysis using random effect models showed a significant reduction of UTIs when stents were removed earlier than three weeks (OR 0.49, CI 95%, 0.33 to 0.75, p = 0.0009). Regarding incidence of urinary leakage, there was no significant difference between early (<3 weeks) and late stent removal (>3 weeks) (OR 0.60, CI 95%, 0.29 to 1.23, p = 0.16). Based on our results, earlier stent removal (<3 weeks) was associated with a decreased incidence of UTIs and did not show a higher incidence of urinary leakage compared to later removal (>3 weeks). We recommend that the routine removal of ureteric stents implanted during KTx should be performed around three weeks post-operatively.

Background. Ureteric stent insertion is performed at the time of renal transplant to minimise the risk of post-operative urological complications, including anastomotic leak and ureteric stenosis or obstruction. Transplant ureteric stent removal (TUSR) has historically been performed via flexible cystoscopy, predominantly in a theatre setting. Isiris™ is a single-use cystoscope with integrated grasper designed for removal of ureteric stents. We report our initial experience. Methods. A retrospective analysis of a contemporaneously maintained database was performed with review of case notes from October 2017 to September 2018. TUSR was performed by surgical middle grades with a single nurse assistant. Results. One hundred and fifty ureteric stents were removed in transplant recipients (mean age 50.2 years, SD ± 15.2; 61.3% male). 91.3% ( n = 137) of cases were performed in the outpatient clinic. Median time to TUSR was 42 days (IQR 30-42). 147 attempts at removal were successful. One urinary tract infection (UTI) was reported following TUSR. Use of the Isiris™ for TUSR corresponds to a £63,480 saving in this cohort compared to conventional practice. This value is conservative and does not include income that has been gained from the reallocation of operating theatre capacity. Conclusion. Isiris™ can safely be employed for the timely performance of non-complicated TUSR. Isiris™ releases this procedure from the confines of the operating theatre to the outpatient clinic. This reduces the resource burden for healthcare providers and may result in improved patient satisfaction. The environmental implications of disposable healthcare equipment require consideration. Evaluation of Isiris™ TUSR for encrustation is required.

Transplantation in elderly patients is obviously more challenging due to existing underlying diseases, changes in pharmacokinetics of immunosuppressive drugs, polypragmasy, and transformation of immunoreactivity (immunosenescence). Our review presents data on modification of adaptive and innate immunity during aging. It also considers the possibility of both reduced and adapted immunosuppressive therapy in elderly renal transplant recipients in achieving an optimal balance between efficacy and complications.

Despite an increasing quality of life after renal transplantation, the number of recipients undertaking paid professional work remains relatively low. Employment after kidney transplantation became a new important marker of clinically significant health recovery. Furthermore, for social and economic reasons, returning to work and participation in social life may be considered as an objective parameter that demonstrate the effectiveness of transplantation. The objectives of the following study were to evaluate the factors that determine resuming paid work after renal transplantation, to assess a patient’s decision about returning to professional activity by comparative analysis of renal transplant recipients from Poland, Czech Republic and Germany, and to identify groups of patients exposed to professional exclusion in those EU countries. Five hundred renal transplant recipients from three EU countries were included into the study. The two main research methods used in the study were the SF-36 questionnaire, constructed and validated to assess the quality of life after kidney transplantation and a questionnaire constructed for the purposes of this study. Multifactorial analysis identified several risk factors associated with professional exclusions after kidney transplantation, namely young or advanced age, female gender, lack of education, place of residence in rural areas, long period of illness, and lack of occupational activity before transplantation. Despite the high standards of social care and rehabilitation support, patients in Germany failed to take up professional activity after kidney transplantation in more cases than those in Poland and Czech Republic. Surprisingly, the objective function of the kidney (creatinine level) and the multidimensional assessment of quality of life (SF-36 survey) did not have a significant association with the employment status after renal transplantation.

Abstract Background and Aims New onset diabetes (NODAT) is a common complication after kidney transplantation. The available treatment options in this patient population have limitations due to reduced renal function, possible interactions with immunosuppressive drugs and side effects such as hypoglycemic events. The aim of this study was to investigate the long term safety and efficacy profile of dipeptidyl peptidase-IV (DDP-4 inhibitors) administration in renal transplant recipients with NODAT. Method The study included 12 patients treated with DPP-IV inhibitors monotherapy as well as 5 patients receiving insulin monotherapy as initial treatment immediately after NODAT diagnosis. All patients were monitored at every scheduled outpatient visit and for 12 months after diagnosis by measuring glycosylated hemoglobin (HbA1c), serum creatinine (eGFR calculation with CKD-EPI formula), plasma immunosuppressive trough levels, serum lipids, blood pressure, and body weight. The mean values of the aforementioned parameters for the last six months of follow up were compared to the ones at diagnosis. Results Patients receiving DPP-IV inhibitors were treated with either linagliptin (4 patients), sitagliptin (4 patients), vildagliptin (2 patients) or halogliptin (2 patients). These patients had a mean age of 59.4 ± 12 years, a mean HbA1c of 6.6% and a mean fasting glucose of 114.5 mg/dl at diagnosis. The mean HbA1c the last 6 months of one year of follow up after initiation of treatment, decreased to 6.1% (p=0.03). Renal function remained stable (mean eGFR from 58.8 to 61.7 ml/min/1.73m2, p=ns) while plasma tacrolimus levels did not appear to be affected (from 6.2 to 5.5 ng/dl, p=ns). Patients received a slightly reduced mean dose of tacrolimus during the last six months of follow up in comparison to the one at initiation of treatment (from 2.9 to 2.6 mg/24h, p=ns). No significant difference was shown in serum total, LDL, and HDL cholesterol before and after treatment, nevertheless, triglyceride levels were significantly reduced (from 214.4 to 174.9 mg/dl, p=0.0039). A decrease in body weight was observed (from 79.9 to 77.9 kg, p=ns) which was however not statistically significant. Finally, achieving the goal of lowering HbA1c levels was better in patients treated with DPP-IV inhibitors than in those treated with insulin (6.1% vs 7.1%, respectively, p=0.01). Conclusion Administration of DPP-IV inhibitors appears to be a safe and effective option for the treatment of NODAT in renal transplant recipients with the benefit of avoiding hypoglycemic episodes and possibly better diabetes control than with insulin therapy.
