Insights
Ectopic ureteroceles and duplex systems lead to higher reoperation rates after endoscopic treatments. This systematic review highlights key factors influencing outcomes in ureterocele management.
Area of Science:
- Urology
- Pediatric Urology
- Surgical Outcomes
Background:
- Ureteroceles are congenital anomalies of the upper urinary tract.
- Endoscopic management is a common treatment modality for ureteroceles.
- Understanding factors influencing treatment success is crucial for patient care.
Purpose of the Study:
- To evaluate endoscopic ureterocele treatment outcomes.
- To determine the impact of ureterocele location (intravesical vs. ectopic) on success rates.
- To assess the influence of urinary system anatomy (single vs. duplicated) on reoperation rates.
Main Methods:
- Systematic review and meta-analysis adhering to PRISMA standards.
- Inclusion of studies on endoscopic transurethral incision and puncture for ureteroceles.
- Comparative analysis based on ureterocele location, system anatomy, and preoperative reflux.
Main Results:
- Analysis of 83 studies involving 3022 patients.
- Higher reoperation risk for ectopic ureteroceles compared to intravesical ones (RR: 2.42).
- Increased reoperation rates observed in duplex system ureteroceles versus single system ureteroceles (RR: 2.50).
Conclusions:
- Ectopic ureteroceles are associated with significantly higher reoperation rates.
- Duplex system ureteroceles also demonstrate a higher likelihood of requiring reoperation.
- These findings emphasize the importance of anatomical factors in endoscopic ureterocele treatment planning.
Objective:
To assess the results of endoscopic ureterocele treatments as well as the effects of ureterocele location (intravesical vs. ectopic) and anatomy (single vs. duplicated system) on treatment outcomes.
Material And Methods:
Following the Systematic Reviews and Meta-Analyses (PRISMA) standards, several medical databases as well as Google Scholar were searched comprehensively. Studies describing secondary operation outcomes for endoscopic transurethral incision and puncture were included. Studies were required to compare patients according to ureterocele location (intravesical or ectopic) and anatomy (single or duplex system) or preoperative reflux. Meta-analysis was conducted using Comprehensive Meta-analysis (CMA) software.
Results:
A total of 83 studies entered this systematic review consisting of 3022 patients. According to the meta-analysis of 16 studies, the risk ratio (RR) of reoperation after ureterocele incision was significantly higher in patients with ectopic vs. intravesical ureteroceles (RR: 2.42; 95% CI: 1.89-3.11; P < 0.001; I2: 14.89%). Also, a higher reoperation rate was reported in patients with duplex system ureteroceles (DSU) vs. single system ureteroceles (SSU) with little heterogeneity based on 9 studies. (RR: 2.50; 95% CI: 1.60-3.91; P < 0.001; I2: 13.83%).
Conclusion:
Our results showed that ectopic ureteroceles and duplex systems are associated with higher reoperation rates after endoscopic procedures.
