The treatment options for mixed calcium oxalate and calcium phosphate stones are: conservative treatment, extracorporeal shock wave lithotripsy and surgery.
1. Conservative treatment: Conservative treatment can be tried to promote stone discharge for patients with stone diameter <0.6 cm and no obstruction in the lower urinary tract, which is applicable to both upper and lower urinary tract stones. Specific ways include drinking more water to promote urination. Some patients can pass the stones on their own after treatment. The use of lithotripsy medication can be used under the guidance of a doctor.
2. Extracorporeal Shock Wave Lithotripsy (ESWL): It is suitable for kidney stones with a diameter of ≤2 centimeters and upper ureteral stones. After using ultrasound to locate the stone, high-energy shock waves will be applied to the stone to make it break up and then be discharged with urine.
3. Surgery: For patients with large stone diameter, ineffective of the above treatments, or complicated with urinary tract infection or severe hydronephrosis, patients with upper urinary tract stones should undergo surgery as soon as possible, and according to the condition, they can choose percutaneous nephrolithotripsy to remove the stones, ureteroscopy to remove the stones, ureteral incision to remove the stones and other methods. For larger bladder stones or urethral stones, transurethral cystoscopic lithotripsy is usually adopted.
Patients with mixed calcium oxalate and calcium phosphate stones are advised to go to the hospital as soon as possible to have their condition evaluated by a professional doctor and then formulate a scientific treatment plan.
