Insights
Optimizing ureteral stent length and intravesical position in children can reduce lower urinary tract symptoms and infections. Careful placement minimizes discomfort and urinary tract infections in pediatric patients.
Area of Science:
- Pediatric Urology
- Urological Devices
- Lower Urinary Tract Symptoms
Background:
- Ureteral stents are crucial post-urological procedures but can cause lower urinary tract issues.
- Stent-related irritative symptoms and urinary tract infections are common complications.
Purpose of the Study:
- To investigate the impact of ureteral stent length and intravesical position on lower urinary tract effects in pediatric patients.
- To identify factors influencing stent-related symptoms and infections in children.
Main Methods:
- Retrospective analysis of 47 pediatric patients undergoing double-J stenting.
- Assessment of age, irritative symptoms, urinary tract infections, stent length, and intravesical stent position (cross-trigonal vs. ipsilateral).
Main Results:
- Cross-trigonal stent position correlated with increased urgency, suprapubic pain, and younger age.
- Longer-than-recommended stents and cross-trigonal positions were associated with higher rates of urinary tract infections.
Conclusions:
- Appropriate ureteral stent sizing and strategic intravesical positioning are key to mitigating stent-related complications.
- Tailoring stent characteristics can significantly improve patient outcomes and reduce adverse events in pediatric urology.
Purpose:
Ureteral stents can cause lower urinary tract problems such as stent-related irritative symptoms and urinary tract infections. This study aimed to determine the lower urinary tract effects of ureteral stent length and intravesical position in children.
Methods:
Patients who underwent double-J stenting after urological procedures between January 2017 and January 2022 were included in the study. The patients were assessed in terms of age, irritative symptoms, urinary tract infections, and stent length. The intravesical position of the ureteral stents was grouped as cross-trigonal and ipsilateral. The distribution of irritative symptoms, frequency of urinary tract infections and stent length were analyzed according to intravesical location.
Results:
A total of 47 patients were included in the study. The median age was 5 years (range: 1-16). Cross-trigonal stent position was significantly associated with symptoms of urgency (p = 0.046), suprapubic pain (p = 0.002), and lower mean age (p = 0.004). Urinary tract infections were more frequent in patients whose placed stents were longer than recommended (p < 0.001) or were in cross-trigonal position (p = 0.043).
Conclusion:
Our results suggest that stent-related irritative symptoms and urinary tract infections can be reduced in pediatric patients using a suitably sized ureteral stent and considering its intravesical position.
