If you are unfortunate enough to suffer from ureteral stones, do not hide them, but seek medical attention in time, because they can easily lead to hydronephrosis and urinary tract infection and damage your kidney function if not treated actively. In clinical practice, we have seen many patients who had to have their non-functional kidneys removed because of delayed treatment, which is regrettable. In fact, ureteral stones can be easily cured if they are treated in time. Therefore, I hope the introduction of this article can draw your attention to this common disease of ureteral stones. The vast majority of ureteral stones come from the kidneys, and some ureteral lesions, such as narrowing of the ureteral lumen and poor drainage, can also be secondary to stones. I. Diagnostic points: 1. Severe colic in the affected kidney area or epigastrium with radiation to the perineum. 2, Pain followed by visual or microscopic hematuria. 3, urinary frequency, urinary urgency, urinary pain and other bladder irritation symptoms, lower 1/3 segment ureteral stones are more common. 4.The onset of colic is often accompanied by nausea and vomiting. 5.B ultrasound, X-ray plain film and intravenous pyelogram can find stones. 6.Cystoscopy + retrograde urography: stones at the ureteral bladder opening can be seen, and retrograde urography is feasible, which is more valuable for stones that are not clear on plain film. 7. renogram: the stone side shows an obstruction curve. Non-surgical treatment: For patients with stones < 6mm in diameter, with a tendency to move downward, no obvious effect on kidney function, and no urinary tract infection. Patients can drink a lot of water, take Chinese medicine, apply antispasmodics, jumping activities, etc. 2. Ureteroscopic stone extraction or lithotripsy (URL): upper, middle and lower ureteral stones with a diameter of Q1.5 cm can be used. After ureteral dilatation, the ureteroscope is placed, and the stones are broken up by means of pneumatic ballistics, laser or ultrasound and then discharged out of the body by themselves; smaller stones can also be removed directly with stone extraction forceps. 3.Extracorporeal shock wave lithotripsy (ESWL): This method is preferred for upper ureteral stones with a diameter of Q1.0 cm, while upper segment stones of 1-1.5 cm and middle and lower segment stones of Q1.5 cm can also be selected. Our department has advanced extracorporeal shock wave lithotripter, with thousands of lithotripsy cases, and the good lithotripsy effect is recognized by the majority of patients. 4.Percutaneous nephrolithotomy (PNL): upper ureteral stones with diameter ≥1.5cm above L4 plane are suitable for PNL stone extraction. 5.Open or laparoscopic ureterotomy: It is suitable for patients who have the above treatments not working, whose stones are >1.5cm in diameter, and whose surface is rough and cannot be discharged by themselves, or who have ureteral stenosis and infection.
