Abstrakt:	Background: Major urological complications (MUCs) after kidney transplantation contribute to patient morbidity and compromise graft function. The majority arise from vesicoureteric anastomosis and present early after transplantation. Ureteric stents have been successfully used to treat such complications. A number of centres have adopted a policy of universal prophylactic stenting at the time of graft implantation to reduce the incidence of urine leaks and ureteric stenosis. Stents are associated with specific complications, and some centres advocate a policy of only stenting selected anastomoses. This is an update of our review, first published in 2005 and last updated in 2013. Objectives: To examine the benefits and harms of routine ureteric stenting to prevent MUCs in kidney transplant recipients. Search Methods: We contacted the Information Specialist and searched the Cochrane Kidney and Transplant's Specialised Register (up to 19 June 2024) 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: Our meta-analysis included all randomised controlled trials (RCTs) and quasi-RCTs designed to examine the impact of using stents for kidney transplant recipients. We aimed to include studies regardless of the type of graft, the technique of ureteric implantation, or the patient group. Data Collection and Analysis: Summary estimates of effect were obtained using a random-effects model, and results were expressed as risk ratios (RR) and their 95% confidence intervals (CI). Confidence in the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Main Results: Twelve studies (1960 patients) were identified. One study was deemed to be at low risk of bias across all domains. The remaining 11 studies were of low or medium quality, with a high or unclear risk of bias in at least one domain. Universal prophylactic ureteric stenting versus control probably reduces major urological complications (11 studies: 1834 participants: RR 0.30, 95% CI 0.16 to 0.55; P < 0.0001; I 2 = 16%; moderate certainty evidence; number needed to treat (17)); this benefit was confirmed in the only study deemed to be at low risk of bias across all domains. This benefit was also seen for the individual components of urine leak and ureteric obstruction. Universal prophylactic ureteric stent insertion reduces the risk of MUC in the subgroup of studies with short duration (≤ 14 days) of stenting (2 studies, 480 participants: RR 0.39, 95% CI CI 0.21 to 0.72; P = 0.003; I 2 = 0%) and where stenting was continued for > 14 days (8 studies, 124 participants: RR 0.22, 95% CI 0.08 to 0.61; P = 0.004; I 2 = 29%). It is uncertain whether stenting has an impact on the development of urinary tract infection (UTI) (10 studies, 1726 participants: RR 1.32, 95% CI 0.97 to 1.80; P = 0.07; I² = 60%; very low certainty evidence due to risk of bias, heterogeneity and imprecision). Subgroup analysis showed that the risk of UTI did not increase if short-duration stenting was used (9 days) and that there was no impact on UTI risk when the prophylactic antibiotic regime co-trimoxazole 480 mg/day was used. Stents appear generally well tolerated, although studies using longer stents (≥ 20 cm) for longer periods (> 6 weeks) had more problems with encrustation and migration. There was no evidence that the presence of a stent resulted in recurrent or severe haematuria (8 studies, 1546 participants: RR 1.09, 95% CI 0.59 to 2.00; P = 0.79; I 2 = 33%). The impact of stents on graft and patient survival and other stent-related complications remains unclear as these outcomes were either poorly reported or not reported at all. Authors' Conclusions: Routine prophylactic stenting probably reduces the incidence of MUCs, even when the duration of stenting is short (≤ 14 days). Further high-quality studies are required to assess optimal stent duration. Studies comparing selective stenting and universal prophylactic stenting, whilst difficult to design and analyse, would address the unresolved quality of life and economic issues.
