Insights
This study presents a simple stent and vent technique for ureteropelvic junction repair in children. The method effectively stented the anastomosis and allowed for potential nephrostomy drainage.
Area of Science:
- Pediatric Urology
- Surgical Innovation
- Urologic Reconstruction
Background:
- Ureteropelvic junction (UPJ) obstruction is a common cause of pediatric kidney disease.
- Traditional surgical repair of UPJ obstruction can involve complex stenting and drainage techniques.
Observation:
- A novel technique utilizing a combined 8F feeding tube and 4F ureteral catheter was employed for stenting a UPJ anastomosis.
- The system allowed for stenting, ureteral catheter removal, and subsequent nephrostogram via the feeding tube.
Findings:
- The combined stent and vent system was simple to construct and manage postoperatively.
- The technique successfully stented the anastomosis and provided a conduit for potential nephrostomy drainage.
Implications:
- This technique offers a simplified approach to stenting and drainage after pediatric UPJ repair.
- The described method may be beneficial in select cases, potentially reducing postoperative management complexity.
Purpose:
We report on a simple technique of how to stent and vent the anastomosis after ureteropelvic junction repair in children.
Materials And Methods:
An 8F feeding tube housing a 4F ureteral catheter, each trimmed to different lengths, was used to stent a ureteropelvic junction anastomosis in a 3-year-old girl with 1 functional kidney. On postoperative day 7 the ureteral catheter was removed and a nephrostogram was performed via the remaining feeding tube, which could also function as a nephrostomy tube.
Results:
The combined tubes were simply constructed, easily cared for during the postoperative period, served the purpose of stenting and could provide nephrostomy drainage if necessary.
Conclusions:
We recommend our stent and vent system in select cases of ureteropelvic junction repair.
