Patient: male, 65 years old, recurrent right kidney colic for 1 week. History: right kidney stone was found for 3 years, he came to the hospital of the Tarrytown for renal colic attacks and had no stone removal for a week. CT found a stone in the middle of the right ureter, 6 mm, and moderate hydronephrosis in the right kidney. the patient was also advised to wait for stone removal, but because of the heavy symptoms and the patient’s request to relieve the pain as soon as possible. The decision was made to operate. Diagnosis: right middle ureteral stone and right hydronephrosis. Treatment: Transurethral ureteroscopic lithotripsy was performed. Routine use of F8/9.8 ureteroscope (3 mm diameter) suggested ureteral stricture. The F7.5 ureteroscope (2.5 mm diameter) was then replaced with a holmium laser lithotripsy. The stone was black-brown and very hard, and the laser lithotripsy was successful. (The chance of ureteral stenosis in the population is about 10%.) Summary: Ureteral stones are not large, but rather painful and significant, heavy fluid accumulation, the possibility of stone expulsion is unlikely, and minimally invasive surgical treatment is needed. After surgery, tell the patient that you made the right decision to request surgery! Preoperative CT reconstruction Intraoperative images
