Guidewire through DJ stent
ACTIVE COMPARATORPatients who underwent lithotripsy after guidewire insertion through a previously placed double j stent.
DJ stent remove + guidewire
SHAM COMPARATORPatients who underwent lithotripsy after double j stent removal and guidewire placement.
Interventions
The previously placed double J stent is removed up to the urethral meatus with a cystoscope and forceps and kept fixed at the meatal level without further pulling. Then, after reaching the kidney by passing a guidewire through it, the double j stent is removed. Followed by the routine lithotripsy procedure.
The double j stent is completely removed with the cystoscope and forceps, and the guidwire is inserted into the ureter by visualizing it with the cystoscope. Followed by the routine lithotripsy procedure.
Eligibility Criteria
You may qualify if:
- Double J stent placed at least 2 weeks ago
You may not qualify if:
- Active urinary tract infection
