Outcomes of Early Simultaneous Removal of Ureteric Stent With Indwelling Urethral Catheter After Kidney Transplant in Pediatric Recipients: A 10-Year Review

摘要

Objectives: A ureteric stent is routinely placed to minimize urological complications during kidney transplant. However, some complications may occur in association with the ureteric stent, such as urinary tract infections, and the optimal duration for stent placement is unclear. We reviewed the outcomes following early simultaneous removal of the ureteric stent with the urethral catheter in pediatric kidney transplant recipients. Materials and Methods: We reviewed all kidney transplants from January 2009 to January 2019. The data we collated included demographics, donor and recipient characteristics, and perioperative details, including urological complications, stent-related complications, and kidney graft function. The financial cost of late stent removal was calculated. The early stent removal group was defined as 5 days, and the late removal group was about 4 to 6 weeks. The median follow-up time was 60 months (interquartile range, 31.5-91 months). Results: There were 32 transplants in 31 patients during the study period (early vs late group = 23:9). No urine leak occurred in either group. One patient in the early group developed distal ureteric stenosis, and this condition was managed with interventional balloon dilatation. The median time for stent removal was 6 days in the early group and 39 days in the late group. There were 5 episodes of symptomatic urinary tract infections in 3 patients in the early group and 10 episodes of symptomatic urinary tract infections in 3 patients in the late group. The mean estimated glomerular filtration rate at 12 months was comparable between the 2 groups (84 ± 54 vs 64 ± 21 L/min/1.73 m 2 ; P = .3). The average cost for each early removal was A$772.65 compared with the late group. Conclusions: Early simultaneous removal of the ureteric stent with the urethral catheter in pediatric kidney transplant recipients is feasible, safe, and cost-effective.
