Ureteropelvic junction obstruction screening in siblings is crucial. A significant number of siblings (38%) showed uropathology, with most requiring therapy, highlighting the need for prompt investigation.
Area of Science:
- Pediatric Urology
- Genitourinary Radiology
- Clinical Genetics
Background:
- Ureteropelvic junction (UPJ) obstruction is a common congenital anomaly.
- Genetic predisposition and familial recurrence are observed in UPJ obstruction.
- Early diagnosis and intervention are critical to prevent renal damage.
Purpose of the Study:
- To evaluate the prevalence of uropathology in siblings of patients with UPJ obstruction.
- To determine the necessity of imaging studies in asymptomatic siblings.
- To establish screening guidelines for families with a history of uropathology.
Main Methods:
- Retrospective review of sibling evaluations.
- Intravenous pyelogram (IVP) and voiding cystourethrogram (VCUG) were utilized.
- Analysis of sibling uropathology and subsequent treatment requirements.
Main Results:
- 38% of siblings (14 of 37) exhibited uropathology.
- 93% of affected siblings (13 of 14) required therapeutic intervention.
- 55% of families had more than one child with uropathology.
Conclusions:
- Siblings of children with UPJ obstruction have a high incidence of uropathology.
- Universal screening with IVP and VCUG is recommended for all siblings, irrespective of age or sex.
- Family history of uropathology warrants thorough investigation in pediatric patients.
Abstract:
Thirty-seven siblings of 20 probands with ureteropelvic junction obstruction were evaluated with an intravenous pyelogram (IVP) and a voiding cystourethrogram (VCUG). Fourteen of 37 (38 per cent) had uropathology and 13 of 14 (93 per cent) required some form of therapy. Fifty-five per cent of the families had an additional child with uropathology. The recommendation concluded from this and a previous study on reflux is that all siblings of children with uropathology be investigated with an IVP and VCUG regardless of age or sex.
