Treatment of renal stone is always a challenge. High incidence of
recurrence of renal stone compels the treating physician to opt for minimally invasive treatment. With the advent of extra
corporeal shock wave lithotripsy the treatment has been completely revolutionized. The treatment of lower polar stone
is always tiring, and usually involves multiple modalities, the low lie of the stone, difficult clearance, narrow infundibulum,
and higher incidence of regrowth make it difficult to treat. Objectives: We assessed the role of diuretic in the clearance
of lower polar stone after shock wave lithotrispsy, (SWL). Material and Methods: 60 patients were selected from both
sexes and divide them in two equal groups, with age 20-75 Y for group 1, and 5-72 Y for group II. Stone size from 5-
20mm were included in our study. The patients underwent ESWL. The group I was offered inj Frusemide 20 mg
intravenously after shock wave lithotripsy, while patients in group II were kept as control.Results: The stone clearance
in group I was 73.3, and 60% in group II. Which is quite significant. Conclusion: The use of diuresis after ESWL
significantly increases the clearance rate for lower polar stones.
