Insights
Posterior urethral valves (PUV) can lead to kidney failure in children. Early presentation and normal initial creatinine levels are key predictors of better renal outcomes in boys with PUV.
Area of Science:
- Pediatric Nephrology
- Urology
- Medical Research
Background:
- Posterior urethral valves (PUV) represent a significant cause of childhood end-stage renal disease.
- Understanding predictors of renal impairment in PUV patients is crucial for improving long-term outcomes.
Purpose of the Study:
- To characterize a cohort of pediatric patients diagnosed with posterior urethral valves (PUV).
- To identify factors that predict the development of renal impairment in children with PUV.
Main Methods:
- A retrospective chart review was conducted.
- The study included boys with PUV treated at King Abdulaziz University hospital from 2002 to 2011.
Main Results:
- The cohort consisted of 68 boys.
- Longer follow-up duration, lower nadir serum creatinine, and lower last known serum creatinine were associated with renal impairment.
- Follow-up duration was a significant predictor of serum creatinine doubling (OR, 1.8).
Conclusions:
- Neither PUV ablation nor vesicostomy significantly impacted kidney function in this cohort.
- Early presentation and normal nadir serum creatinine levels were associated with better renal outcomes in children with PUV.
Background:
Posterior urethral valves (PUV) are a common cause of end-stage renal failure in childhood. Our aim was to describe a cohort of patients with PUV and to investigate the predictors of renal impairment.
Methods:
We performed a retrospective chart review of children with PUV who were followed at King Abdulaziz University hospital between 2002 and 2011.
Results:
The cohort comprised 68 boys. There was a significant difference in the duration of follow-up (p = 0.024), nadir serum creatinine (p < 0.001), and last known serum creatinine level (p = 0.001) between the patients with and without renal impairment. The duration of follow-up appeared to be a significant predictor for serum creatinine doubling (p = 0.003; odds ratio, 1.8). There was no difference in the age of presentation, age at the time of the study, and first or last serum creatinine between children who initially had vesicostomy and children who had ablation.
Conclusions:
Ablation of PUV or vesicostomy did not influence kidney function in our study cohort. Children with a normal nadir serum creatinine who presented early had a better outcome.
