Trisomy 13 with retroiliac ureter diagnosed by assessment for recurrent febrile urinary tract infections.

ABSTRACT

Introduction: Patients with trisomy 13 have multiple malformations, including urological anomalies, and severe cognitive and psychomotor disabilities. We conducted a ureteroureterostomy for a mid-ureteral stricture due to a retroiliac ureter in a patient with trisomy 13. Case presentation A 6-month-old girl with trisomy 13 developed a urinary tract infection. Computed tomography for assessing recurrent urinary tract infection revealed a left mid-ureteral stricture due to the retroiliac ureter. At the age of 2, a ureteroureterostomy was performed. Two years after surgery, the urinary tract infection did not recur. Conclusion: Ureteroureterostomy is a safe procedure for children with trisomy 13 and multiple comorbidities. Surgical treatment should be considered for patients with trisomy 13 when agreed upon by the family and comorbidities are well-controlled.
