Effect of urinary stone disease and its treatment on renal function

Table 1 Effects of shock wave lithotripsy on renal functions and glomerular filtration rate levels

Ref.	No. of patients	Patients’ feature	Follow-up	Pre-SWLmean ± SD GFR (mL/min)	Post-SWLmean ± SD GFR (mL/min)	P value
Eassa et al[25]	108	Solitary kidney	3. 8 ± 3.5/yr	84.6 ± 24.7	82.5 ± 26.5	0.33
Fayad et al[27]	100	Children	6 mo	113.13 ± 4.51	113.01 ± 4.27	0.46

Difference is considered statistically significant at P < 0.05 and highly significant at P < 0.01. SWL: Shock wave lithotripsy; GFR: Glomerular filtration rate.
