Ureteral ectopia in infants and children
Insights
Ureteral ectopia in children is often diagnosed during urinary tract infection evaluations. Management depends on the collecting system, with duplex systems typically requiring heminephrectomy and single systems amenable to ureteral reimplantation.
Area of Science:
- Pediatric Urology
- Surgical Management
- Congenital Anomalies
Background:
- Ureteral ectopia can present with symptoms like constant wetting in girls or epididymitis in boys.
- Diagnosis is frequently incidental during the workup for pediatric urinary tract infections.
- Ectopic ureters are commonly linked to duplex collecting systems with dysplastic upper poles.
Purpose of the Study:
- To correlate diagnostic findings with surgical approaches for pediatric ureteral ectopia.
- To review surgical outcomes for ectopic ureters over an 11-year period.
- To provide insights into the management of ectopic ureters based on clinical experience.
Main Methods:
- Retrospective review of 48 ectopic ureters in 41 children.
- Analysis of diagnostic findings leading to diagnosis.
- Evaluation of surgical interventions, including upper pole heminephrectomy and ureteral reimplantation.
Main Results:
- Ectopic ureters associated with duplex systems were primarily managed with upper pole heminephrectomy and partial ureterectomy.
- In cases with single collecting systems, ureteral reimplantation was feasible when salvageable renal function was confirmed preoperatively.
- The study analyzed 48 cases over 11 years, correlating diagnosis and surgical treatment.
Conclusions:
- Surgical management of pediatric ureteral ectopia should be tailored to the underlying collecting system anatomy.
- Upper pole heminephrectomy is the preferred approach for ectopic ureters in duplex systems.
- Ureteral reimplantation offers a viable option for ectopic ureters in single systems with preserved renal function.
Abstract:
The diagnosis of ureteral ectopia may be suspected in the girl who wets constantly or in the young boy with epididymitis. More commonly, however, the diagnosis is made during evaluation of the child with urinary tract infection. The ectopic ureter is most often associated with a poorly functioning dysplastic upper pole of a duplex collecting system and in this instance it is best managed by upper pole heminephrectomy and partial ureterectomy. When associated with a single collecting system, ureteral reimplantation can often be performed if salvageable function is demonstrated by a preoperative renal scan. Based on our experience with 48 ectopic ureters in 41 children operated on during the last 11 years, the correlation of the diagnostic findings and surgical approaches to this entity are discussed.
