My pathway: before, during, after
01Indications
Treat selected ureter or kidney stones according to size, location and effects.
02Preparation
Imaging and infection assessment; an infected obstruction needs drainage before definitive stone treatment. Follow individual anaesthetic advice.
03What happens
An endoscope enters through the natural urinary passage. The stone is extracted or fragmented, often with a laser; a JJ stent may be placed.
04Follow-up
Check clearance and arrange stent removal. Stone analysis helps plan recurrence prevention.
05Expected results
Can clear the urinary passage; more than one session may be needed.
06Risks and limitations
Infection, ureter injury, remaining fragments and stent discomfort are possible.
