Insights
Nephrectomy cured hypertension in two-thirds of children with a poorly functioning kidney. Laparoscopic nephrectomy is a potential first-line treatment for pediatric hypertension caused by a poorly functioning kidney.
Area of Science:
- Pediatric Nephrology
- Pediatric Urology
- Surgical Outcomes
Background:
- Hypertension (HTN) in children can be linked to a unilateral poorly functioning kidney (PFK).
- Nephrectomy offers a potential cure for HTN, avoiding long-term medication.
- Limited data exists on the effectiveness of PFK nephrectomy in pediatric HTN.
Approach:
- A systematic review and meta-analysis of studies published between 2000 and 2020.
- Identified and analyzed 5 articles involving 88 children with PFK and HTN who underwent nephrectomy.
- Assessed HTN resolution as the primary outcome, excluding duplicate, review, and incomplete articles.
Key Points:
- Unilateral atrophic kidney with or without VUR was the most common cause of PFK (43%).
- Ureteropelvic junction obstruction and multicystic dysplastic kidney accounted for 35% of cases.
- Renovascular pathology represented 22% of PFK etiologies.
Conclusions:
- Nephrectomy effectively cured HTN in 65.9% of children with PFK.
- Laparoscopic nephrectomy is increasingly utilized and may be the preferred treatment.
- PFK nephrectomy is a viable option for managing pediatric hypertension.
Purpose:
Some children with hypertension (HTN) have unilateral poorly functional kidney (PFK). This provides an opportunity for the clinician to cure the HTN by removal of the PFK, thereby avoiding the problems of long-term medication. However, there is sparse data in children regarding the effect of PFK nephrectomy on curing HTN. In this review, we analysed the etiology of PFK causing HTN and the effectiveness of nephrectomy in curing HTN in children.
Methods:
We searched the databases to identify papers between January 2000 to December 2020 pertaining to children with PFK and HTN who underwent nephrectomy. Outcome analyzed was the resolution of HTN following nephrectomy. Duplicate publications, review articles and incomplete articles were excluded. Meta-analysis of heterogeneity was reported with I2statistics. Forest plot was constructed to compare the pooled prevalence of HTN resolution.
Results:
Five articles with 88 patients were included. Majority (43%) of PFK were due to the unilateral atrophic kidney with or without vesicoureteral reflux (VUR); ureteropelvic junction obstruction and multicystic dysplastic kidney together accounted for 35% of cases and renovascular pathology for 22% of cases. With a follow-up of 1.5 to 3.3 years, nephrectomy was effective to cure HTN in 65.9% (95% CI 55-75%) children.
Conclusions:
In children with HTN and a unilateral PFK, nephrectomy cured the HTN in two-thirds of children. Unilateral atrophic kidney due to VUR was the most common cause of PFK. An increase in the utilisation of laparoscopy was observed in recent publications, hence laparoscopic nephrectomy may be considered a first choice of treatment in these children.
