Insights
Open-ended urethral catheters significantly reduce catheter obstruction in pediatric hypospadias repair patients. This simple modification offers a safer, more effective postoperative experience, decreasing the need for interventions.
Area of Science:
- Pediatric Urology
- Surgical Innovation
- Medical Device Engineering
Background:
- Urethral catheter obstruction is a common complication in pediatric patients post-hypospadias repair.
- Standard Foley catheters may contribute to this issue, impacting patient recovery.
Purpose of the Study:
- To evaluate the effectiveness of open-ended urethral catheters with two side holes in preventing catheter obstruction.
- To compare the obstruction rates between standard and modified catheters in pediatric hypospadias surgery.
Main Methods:
- Retrospective analysis of clinical data from pediatric patients undergoing hypospadias repair (January 2021 - October 2023).
- Patients were divided into two groups: Group A (standard Foley catheters) and Group B (modified open-ended catheters).
- Primary outcome measured was the incidence of catheter obstruction within seven days postoperatively.
Main Results:
- A total of 297 patients were analyzed (142 in Group A, 155 in Group B).
- Catheter obstruction occurred in 8.5% of Group A patients, requiring irrigation or suprapubic catheterization.
- Group B showed a significantly lower obstruction rate of 2.6%, with obstructions easily managed by irrigation (p < 0.05).
Conclusions:
- Open-ended urethral catheters with two side holes are effective in reducing postoperative catheter obstruction in pediatric hypospadias repair.
- This simple modification offers a significant improvement in patient outcomes and is recommended for clinical practice.
Backgrounds:
Urethral catheter obstruction is a notable issue that pediatric patients with hypospadias may encounter in the early postoperative period. This retrospective study aims to assess the efficacy of open-ended urethral catheters with 2 side holes in mitigating catheter obstruction in pediatric patients following hypospadias repair.
Materials And Methods:
The clinical data of pediatric patients who underwent hypospadias repair surgery from January 2021 to October 2023 were retrospectively collected. The patients were divided into 2 groups. Those who used standard Foley catheters were referred to as Group A, while those who used modified open-ended catheters were referred to as Group B. The primary outcome was the incidence of catheter obstruction within 7 days postoperatively.
Results:
A total of 297 patients were included in this study, with 142 patients in Group A and 155 patients in Group B. In Group A, there were 12 cases of catheter obstruction, with 10 cases resolved through irrigation and 2 cases requiring additional catheters insertion by suprapubic bladder punctures. In Group B, only 4 cases experienced catheter obstruction, which were effectively and easily resolved through maneuver irrigation. The incidence of catheter obstruction in Group B was statistically significantly lower than that in Group A (2.6% vs. 8.5%, p < 0.05).
Conclusion:
In pediatric hypospadias patients who underwent surgical repair, the use of open-ended urethral catheters with 2 side holes significantly diminishes the incidence of postoperative catheter obstruction. This simple technique is worthy of promotion.
