Ureterography may be caused by ureteral stenosis, ureteral stone, ureteral tumor, etc. General treatment, medication, surgery, etc. should be taken according to the cause of the disease.
1. Ureteral stenosis: patients with ureteral stenosis may show non-appearance on ureterography, and laparoscopic pyeloureteroplasty is feasible if necessary.
2. Ureteral stone: For patients with ureteral stone causing ureterography not showing up, extracorporeal shock wave lithotripsy, percutaneous nephrolithotripsy lithotripsy, ureteroscopic ureterolithotripsy, etc. can be performed according to the size and nature of stone.
3. Ureteral tumor: ureterography will not show up when the patient has ureteral tumor, at this time, surgery can be taken to remove the cancerous ureter.
