Male, 36 years old. History of right ureteral stone for 10 years and right low back pain for 1 month. He was treated with ESWL once and no stone was expelled without other treatment (including anti-infection treatment). There was no elevation in the right kidney area, mild percussion pain, pressure pain in the upper part of the right ureter, and the lower pole of the right kidney could be palpated under the ribs without pressure pain. Ultrasound: the right kidney was enlarged with thin cortex. The collecting system was clearly separated, and a strongly echogenic light mass was seen in the lower pole of the right kidney, followed by acoustic shadow. The right ureter is dilated in the upper segment, and a strong echogenic cluster of approximately 2.0 cm is seen 5 cm from the outlet of the renal pelvis, followed by acoustic shadowing. KUB and CT are shown in Fig. Diagnosis: right kidney and right ureteral calculus There were three options in the treatment idea before surgery in this case, and the final plan was made by the patient, which of course was the one with the best expected outcome and higher risk. 1. Ureteroscopic lithotripsy, which mainly addresses ureteral obstruction. However, there is a high possibility of stone migration upwards and stone residual, and intrarenal stones cannot be dealt with. There is a possibility of ureteral perforation and bacteraemia. 2.Posterior laparoscopic right ureterotomy for stone extraction, ureteral stones can be removed intact, and intrarenal stones are not treated. 3, percutaneous nephrolithotomy. Intrarenal stones can be treated, with the possibility of bleeding, even right nephrectomy and bacteraemia, as well as the possibility of stone residue. The result of this case: first prone percutaneous nephrolithotomy to deal with stones in the lower renal calyces, percutaneous nephrolithoscopy through the renal pelvis to the ureteral exploration failed to reach the stone segment ureter, and changed to intercepted position ureteroscopic lithotripsy, a phase of successful resolution of intrarenal and ureteral stones, to meet the patient’s requirements. Our principle is: no open surgery if minimally invasive treatment is possible, and no minimally invasive surgery if non-invasive treatment is possible.
