An adult ureterocele complicated by a large stone: A case report.

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.
