CLINICAL OUTCOME OF RENAL CALCULI PATIENTS UNDERGOING EXTRACORPOREAL SHOCK WAVE LITHOTRIPSY WITH AND WITHOUT DJ STENT

BACKGROUND ESWL is suitable for stones smaller than 2 cm situated in upper and middle calyx. The routine insertion of DJ stents during ESWL of renal calculi is controversial. Some studies support the role of DJ stents in facilitating stone passage and preventing renal colic whereas other reports claim that stent causes significant lower urinary tract symptoms, hematuria, urinary tract infection and can even lower the stone-free rate. METHODS This is a prospective study conducted among 81 patients each in stented and non stented group who underwent ESWL for renal calculus. The primary outcome measured was stone fragmentation .The secondary outcomes measured were renal colic, urinary tract infection, steinstrasse and stent related LUTS. RESULTS Stone fragmentation rates in stented and non-stented groups were 91.4% and 86.4% respectively (p-value > 0.05). Ureteric colic in the stented group was only 14.8% but 45.7% in the non-stented group had ureteric colic (p-value
