With the improvement of living standard and the change of diet structure, there are more and more patients with urinary tract stones, and many patients do not know what to do when they have urinary tract stones. Some patients are very nervous and run to the hospital all day, while others do not take it seriously and end up delaying their condition. I hope this article will be helpful to you. Kidney stone treatment principles: 1, less than 0.6cm kidney stones, generally asymptomatic, can be conservative treatment, drink more water, every six months B ultrasound review on the line. 2. For stones larger than 0.6cm and smaller than 2.5cm, extracorporeal shock wave lithotripsy is generally preferred. For stones larger than 2.5cm, percutaneous nephrolithotomy is preferred, combined with extracorporeal shock wave lithotripsy if necessary. Principles of ureteral stone management: In acute attack of renal colic, anti-inflammatory and analgesic symptomatic treatment can be given first. If the stone is less than 0.6 cm, it is more likely to be discharged by itself, so conservative treatment is feasible. If the stone is large or cannot be discharged by itself for a long time, extracorporeal shock wave lithotripsy is preferred, and ureteroscopic lithotripsy is preferred for female patients with lower ureteral stones who have not had children. This is because extracorporeal shockwave has the potential to cause habitual abortion. In patients with ureteral stones with significant hydronephrosis, extracorporeal lithotripsy is less effective. Percutaneous nephrolithotomy may be considered for upper ureteral stones, and ureteroscopic lithotripsy is feasible in the middle and lower ureter. Laparoscopic surgery may also be considered in some cases.
