The Usage of a JFil® Stent as a New Stenting Method in the Setting of Anderson-Hynes Pyeloplasty

INTRODUCTION: Pyeloplasty is a common reconstructive procedure in urology, traditionally involving internal stenting to enhance drainage and healing. However, conventional Double-J (DJ) stents are associated with complications such as discomfort, infection, and migration. MATERIALS AND METHODS: This prospective pilot study evaluates the feasibility and clinical outcomes of using the JFil® stent, an alternative designed for improved patient tolerance and reduced complications, in robot-assisted Anderson-Hynes pyeloplasty. Four patients underwent the procedure with intraoperative JFil® stent placement. Outcomes were assessed through follow-up imaging, renal function tests, and a stent-specific symptom questionnaire. RESULTS: Results showed no peri- or postoperative complications of Clavien-Dindo ≥ grade III and improved postoperative kidney function. The questionnaire scores indicated minimal postoperative discomfort. CONCLUSION: While the study's small sample size limits generalizability, findings support the JFil® stent as a promising alternative in pyeloplasty. Further research with larger cohorts is recommended to validate these results.
