[Fold formations in the proximal ureter].
Summary
Ureteral membranes in children are typically benign and resolve on their own. These congenital anomalies, often diagnosed in infancy, rarely require surgical intervention and usually do not cause long-term kidney issues.
Area of Science:
- Pediatric Urology
- Congenital Anomalies
- Urogenital System Development
Context:
- Mucosal membranes of the proximal ureter are rare congenital anomalies.
- Diagnosed via intravenous urography in children aged 4 weeks to 11 years.
- Often identified within the first year of life, predominantly in males.
Purpose:
- To evaluate the natural history and clinical significance of ureteral membranes in pediatric patients.
- To assess the association with urinary tract infections (UTIs) and renal obstruction.
- To determine the necessity of urologic intervention for these anomalies.
Summary:
- Over 13 years, 28 children presented with ureteral membranes, with 61% diagnosed in the first year.
- Associated urogenital anomalies were noted in 7 cases; 45% showed minor signs of obstruction.
- Urinary tract infections occurred in 50% of cases, but surgical correction was never needed.
- Follow-up revealed recurrent UTIs in only 2 patients, with normal renal function and kidney size.
- Ureteral membranes are considered harmless, transitory anomalies of the growing ureter in childhood.
Impact:
- Demonstrates the benign, self-resolving nature of ureteral membranes in children.
- Suggests that ureteral membranes do not necessitate urologic intervention.
- Highlights the low risk of long-term renal compromise despite potential association with UTIs.
