Study Arms (2)

Microperc surgery

EXPERIMENTAL

Patient is turned into prone position and the desired calyx is punctured by 4.8F microperc under fluoroscopic or sonographic guidance. No tract dilation is needed. A 200um holmium laser fiber will be used to break stone into less than 2mm. Pull out microperc without drainage tube left.

Procedure: Microperc surgery

FURS

ACTIVE COMPARATOR

Patient is placed in the lithotomy position, pull out the pre-inserted double J, and place guidewire into the renal pelvis. A 12/14 Fr ureteral access sheath (UAS) is advanced into the proximal ureter over the guidewire, and flexible ureteroscope is passed through the UAS. The stones are fragmented smeller than 2mm using a 200um holmium laser fiber. Fragments are removed using a stone basket for stone analysis if necessary, a double J stent is placed at the conclusion of the procedure and removed post-operative 4 weeks.

Procedure: FURS

You may qualify if:

  • mm lower pole renal stone measured by KUB or CT;
  • Age between 18-60 years, no gender limitation;
  • Participators can understand the research and sign the consent form without mental illness nor language disorder;
  • Low pole renal stone left after lithotripsy;
  • Lower pole infundibulopelvic angle which measured by IVP or CTU will less than 30 degree;
  • Asymptomatic patients with positive urine white blood cells and negative preoperative urine culture should be treated with antibiotics for 3days before operation;
  • Patients with symptoms of urinary infections, positive urine withe blood cells and positive preoperative urine culture should be treated with suitable antibiotics based on the culture sensitivity result for at least 7days before operation.

You may not qualify if:

  • Transplant kidney stone;
  • Renal malformations, such as UPJO, medullary sponge kidney, polycystic kidney, horseshoe kidney, etc.;
  • Combine other part of urinary stones need to be handle at the same procedure, for example ureteral stone, renal pelvic stone, middle or upper pole renal stone;

  • Middle or severe hydronephrosis(dilatation of the renal pelvis ≥20mm by ultrasound);
  • Women in menstrual period or pregnancy;
  • Patients have severe disease, such as heart disease, lung dysfunction, and multiple organ failure that cannot tolerate anesthesia or operation.
