Double J Stenting and Sildosin After URSL for Lower Ureteric Stones

Comparative Study Between DJ Stenting and Sildosin After Uretroscopic Lithotripsy for Lower Ureteric Stones

The aim of this prospective comparative clinical study to compare DJ stenting and Sildosin after ureteroscopic lithotripsy for lower ureteric stones.

Ureteric calculi are known to affect approximately 10 - 15% of the overall population. The incidence of urolithiasis is rising over time. Most of these stones are known to pass spontaneously with or without expulsive medical therapy. The expulsion of calculus depends on the following factors: the calculus size and the location in the ureter (Alelign and Petros, 2018). The calculi expulsion rates change depending on these factors, with the expulsion rate ranging from 40% to 98% for calculi less than 5 mm. The calculi, which measure 6 mm or more have a spontaneous expulsion rate ranging between 35% to 50%.

Semirigid ureteroscopy (URS) lithotripsy has been shown to have high success rates for treating distal ureteric stones in many studies. However, URS is associated with some drawbacks, which may be risky and sometimes problematic.

The use of Double J (DJ) stent after ureteroscopy helps in the passage of residual fragments and prevents pain caused due to mucosal edema and obstruction. However, many patients complain of stent-related discomfort in the postoperative period. There is an additional need for stent removal, which is another surgical procedure adding to the cost of treatment. Despite its usefulness, the morbidity associated with these stents has been considered a potential health problem.

Silodosin is a highly selective alpha-1 adrenergic receptor antagonist which is used in the treatment of lower urinary tract symptoms (LUTS). Alpha-1 adrenergic receptors are densely found in the smooth muscle cells of the lower urinary tract, and silodosin relaxes them and improves the stent-related symptoms (SRS), and various studies have also shown similar effects. It has documented its use in the therapy of ureteric calculus.
