Insights
Shock wave lithotripsy (SWL) does not impede normal kidney growth in pediatric patients. This finding holds true regardless of the number of stones or the child's age at the time of SWL treatment.
Area of Science:
- Pediatric Urology
- Nephrology
- Medical Imaging
Background:
- Renal stone disease is a significant concern in pediatric populations.
- Shock wave lithotripsy (SWL) is a common treatment modality for pediatric kidney stones.
- Concerns exist regarding the potential impact of SWL on renal growth and development in children.
Purpose of the Study:
- To evaluate the effect of shock wave lithotripsy (SWL) on kidney growth in children.
- To compare renal growth rates in children treated with SWL to a control group.
Main Methods:
- Prospective controlled study involving 150 children with renal stones undergoing SWL (group A) and 100 healthy children (group B).
- Abdominal ultrasound was used to measure bipolar renal length at baseline, 6 months (group A), and 1 year (both groups).
Main Results:
- Kidney size significantly increased in the SWL group at 6 months and 1 year post-treatment.
- Renal growth rates did not differ significantly between children treated with SWL and normal controls.
- Factors such as patient age, number of SWL sessions, and stone burden did not impact the rate of kidney growth.
Conclusions:
- Shock wave lithotripsy does not have a detrimental effect on the normal growth trajectory of kidneys in children.
- The efficacy and safety of SWL for pediatric kidney stones are supported, with no observed negative impact on renal development.
Purpose:
We investigated whether shock wave lithotripsy affects kidney growth in children.
Materials And Methods:
This prospective controlled study included 150 children with renal stones who presented for shock wave lithotripsy between March 2005 and February 2010 (group A). The control arm included 100 children without any urological problems who were enrolled in the study after obtaining written maternal consent (group B). All children in both groups underwent abdominal ultrasound to assess renal size (bipolar renal length), which was repeated after 6 months for group A and after 1 year for both groups.
Results:
Bipolar renal size in group A increased significantly at 6 months and 1 year after shock wave lithotripsy. Renal growth did not differ based on patient age at shock wave lithotripsy (p = 0.472), number of shock wave lithotripsy sessions (p = 0.65) or number of stones (p = 0.405). There was no significant difference between the rate of kidney growth in children who underwent shock wave lithotripsy during the year of the study and normal controls.
Conclusions:
Shock wave lithotripsy has no deleterious effect on the normal rate of renal growth in children. This outcome is not affected by either the number of stones or the age of the child at shock wave lithotripsy.
