Endoscopic injection of polytetrafluoroethylene (PTFE) paste successfully treated refluxing duplex ureters in children. Most patients showed resolved or reduced reflux, with one developing obstruction.

Area of Science:

  • Pediatric Urology
  • Minimally Invasive Surgery
  • Ureteral Reflux Management

Background:

  • Refluxing duplex ureters in children present a significant clinical challenge.
  • Endoscopic injection is a minimally invasive option for managing vesicoureteral reflux (VUR).

Purpose of the Study:

  • To evaluate the efficacy of endoscopic polytetrafluoroethylene (PTFE) paste injection for treating refluxing duplex ureters in pediatric patients.
  • To assess the outcomes and potential complications associated with this minimally invasive procedure.

Main Methods:

  • Thirty-four children with 35 refluxing duplex ureters underwent endoscopic injection of PTFE paste.
  • Follow-up included assessment of reflux resolution, reduction in reflux grade, and monitoring for complications.

Main Results:

  • Successful reflux resolution or significant reduction was observed in 28 out of 32 (87.5%) followed patients.
  • Twenty-one patients (65.6%) ceased refluxing, while 7 (21.9%) showed a significant reduction in reflux grade.
  • One patient (3.1%) experienced ureteric obstruction; contralateral single system reflux resolved in 8 patients.

Conclusions:

  • Endoscopic PTFE paste injection is an effective treatment for refluxing duplex ureters in children, offering high success rates.
  • The procedure demonstrates a favorable safety profile, with minimal complications reported.
  • This technique also appears effective in resolving concurrent contralateral single system reflux.
