Conditions

Health Condition 1: N202- Calculus of kidney with calculus of ureter

Interventions

Intervention1: Placement of complete intraureteric stent on string: Following upper tract ureteroscopic stone removal

complete intraureteric stent with string will be inserted

for period less than or equal to 1 week Control Intervention1: Conventional double J stents: Following upper tract ureteroscopic stone removal

conventional double J stent will be inserted in comparator arm

for a period less than or equal to 1 week

Eligibility

Inclusion criteria

Inclusion criteria: All patients who have a ureteric stent inserted after upper tract ureteroscopic procedures for unilateral stone disease

Exclusion criteria

Exclusion criteria: pediatric patients, patients undergoing bilateral procedures, anatomical abnormalities, solitary functioning kidney, incomplete treatment, planned for staged procedures, coexisting non calculous diseases, prior ureteric stenting, impacted vesico-ureteric junction calculus and complicated URSL requiring long term stent placement
