Insights
Adult ureteroceles can present with stones and are effectively managed with endoscopic procedures. This approach involves ureterocele deroofing and stone removal, with long-term follow-up recommended.
Area of Science:
- Urology
- Congenital Anomalies
- Endourology
Background:
- Ureterocele is a congenital cystic dilatation of the lower ureter, presenting diverse challenges.
- It affects 1 in 4000 individuals and can be associated with other anomalies.
- A notable adult presentation is a ureteral stone within the ureterocele.
Purpose of the Study:
- To report a case of adult ureterocele complicated by a large calculus.
- To describe the endoscopic management of this condition.
- To review the literature on ureterocele and calculus management.
Main Methods:
- Endoscopic management including transurethral deroofing of the ureterocele.
- Cystolitholapaxy for stone removal.
- Comprehensive literature review.
Main Results:
- Successful endoscopic management of an adult ureterocele with a large calculus.
- Demonstrated feasibility of combined transurethral deroofing and cystolitholapaxy.
- Literature supports endoscopic approaches for ureterocele-associated stones.
Conclusions:
- Endoscopic treatment is effective for ureteroceles complicated by stones.
- Management requires consideration of ureterocele type and patient age.
- Long-term monitoring for hydronephrosis and reflux is crucial post-treatment.
Introduction:
Ureterocele is a cystic dilatation of the lower part of the ureter. It is a congenital anomaly that is associated with other anomalies such as a duplicated system, and other diseases. It poses a great challenge owing to its numerous types and clinical presentations. Its incidence is 1 in every 4000 individuals. One of its presentations in the adult population is the presence of a stone, usually a solitary stone, inside the ureterocele.
Case Presentation:
We are reporting a case of an adult ureterocele complicated by a large calculus; managed endoscopically with transurethral deroofing of the ureterocele followed by cystolitholapaxy. A literature review was also conducted.
Discussion:
The pathogenesis of ureteroceles is not well understood, however many proposed mechanisms exist with the incomplete dissolution of chwalla membrane being the most accepted one. The type of ureterocele and age at presentation will help guide the appropriate investigation and management, nevertheless certain goals of treatment should apply to all cases. Adult ureterocele is usually clinically silent but it may co-exist with other conditions such as a ureteral calculus and in these conditions it can be managed endoscopically.
Conclusion:
Ureteroceles complicated by stones can be effectively managed with endoscopic resection or incision of the ureterocele coupled with stone removal, however long term follow up is required to monitor for hydronephrosis and iatrogenic vesicoureteric reflux.
