Participants	Inclusion criteria: unilateral, single, radio‐opaque distal ureteral stones < 10 mm in size. Exclusion criteria: not available. Diagnostic criteria: not available. Total number of participants randomly assigned: 90. Group A (silodosin) Number of participants randomly assigned: 30. Age (median): not specified. Gender (M/F): not specified. Group B (tamsulosin) Number of participants randomly assigned: 30. Age (median): not specified. Gender (M/F): not specified. Group C (placebo) Number of participants randomly assigned: 30 Age (median): not specified Gender (M/F): not specified
Interventions	Group A (n = 30): 8 mg silodosin daily. Group B (n = 30): 0.4 mg tamsulosin daily. Group C (n = 30): not given any of the above medications. Co‐interventions: not specified.
Outcomes	Stone clearance How measured: not specified. Time points measured: not reported. Time points reported: not reported. Subgroup: none. Complications How measured: during the surgical procedure direct visualisation. Time points measured: at the time of surgery. Time points reported: not reported. Subgroup: none.

Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Quote from publication: "Patients were randomised into three groups...." Not described.
Allocation concealment (selection bias)	Unclear risk	Not described.
Blinding of participants and personnel (performance bias) All outcomes	Low risk	Quote from publication: "placebo‐controlled study".
Blinding of outcome assessment (detection bias) Subjective outcomes	Low risk	Quote from publication: "placebo‐controlled study".
Blinding of outcome assessment (detection bias) Objective outcomes	Low risk	Objective outcomes are not likely to be influenced by lack of blinding.
Incomplete outcome data (attrition bias) Stone free rate	High risk	The number of participants in the analysis were not reported.
Incomplete outcome data (attrition bias) Serious adverse events or complications of treatment	High risk	The number of participants in the analysis were not reported.
Incomplete outcome data (attrition bias) Secondary procedures	Unclear risk	No information given.
Incomplete outcome data (attrition bias) Hospital stay	Unclear risk	No information given.
Incomplete outcome data (attrition bias) Pain	Unclear risk	No information given.
Selective reporting (reporting bias)	Unclear risk	Study outcomes were not specified.
