Urological endoscopy - ureteroscopy

Released on Jan. 28, 2022

Ureteronephroscopy is an important breakthrough in urological endoscopy in recent years, opening up new avenues for the diagnosis and treatment of ureteral and renal diseases.

Indications: It can be divided into two types: for inspection purposes and for treatment purposes:

1) For inspection purposes:

① Diagnosis of excretory urography or retrograde imaging found filling defects in the renal pelvis and ureter, such as light-transmitting stones, papilloma and biopsy of suspicious lesions.

② Unexplained duct stenosis or obstruction.

③ Idiopathic hematuria from the upper urinary tract.

④ Follow-up after local non-radical resection of renal pelvis or ureter tumors.

2) For therapeutic purposes:

①Ureteral calculi, lithotripsy or lithotripsy through ureteroscopy.

②Removal of foreign bodies in renal pelvis and ureter.

③ expansion of ureteral stricture.

④ upper urinary tract bleeding with electrocautery to stop bleeding.


① acute urinary tract infection.

② bladder capacity is too small.

③ Lower urinary tract obstruction (such as urethral stricture or severe prostatic hyperplasia), those who have difficulty in bladder insertion.

④Various factors lead to ureteral fixation, fibrosis, etc., which make intubation difficult or may cause ureteral perforation.

⑤ Have systemic bleeding disorders.


① Ureteral mucosal injury, especially in lithotripsy or lithotripsy, is prone to occur.

②The perforation of the ureteral wall is prone to occur when the ureter itself has lesions.

③ Ureteral stricture is more common in long-term complications after ureteral operation.

④ Infection, more common in those who have been accompanied by infection before surgery.
