Summary

This prospective randomized comparative study was done at Helwan University Hospital. It was conducted on 120 patients with unilateral pelvic renal stones from 1.5 to 3 cm in largest diameter who was admitted through duration to compare the two procedures differences in terms of complications, analgesic use, hospital stay, operational time, and stone-free rates.

Conditions

  • Renal Stones

Interventions

PROCEDURE

percutaneous nephrolithotomy

A 7 Fr ureteric catheter was placed into the ipsilateral ureteric orifice. The patients were then placed in the prone position. Opacification of the pelvicalyceal system was performed. The puncture was done by a 22-guage puncture needle was advanced into the posterior lower calyx under fluoroscopic guidance. After successful access is established, a 0.035-inch curved guide wire was advanced through the puncture needle into the kidney. The central Alkane Rod was passed over the guide wire. Under fluoroscopic guidance serial Amplatz dilators up to 30 Fr were advanced over central Alkane rod and guide wire. Then 30 Fr long Amplatz sheath was advanced over the last dilator. 26 Fr rigid long nephroscope used for stone fragmentation and retrieval. Stone fragmentation was done by pneumatic Swiss Lithoclast. Fragments removal was done using toothed peanut stone retrieval forceps.

PROCEDURE

retrograde intrarenal surgery

urethrocystoscopy was carried out then inserting of a 7F open ended ureteral catheter over the 0.035-inch straight floppy tip guide wire in the working channel of the 22Fr cystoscope under fluoroscopic guidance, access to the ureter was made. Teflon ureteric dilators are used to dilate the distal ureter till 14 FR. ureteral access sheath placement 12 or 14 Fr. OTU, a disposable digital flexible ureteroscope, is then used then the tip of a 272 m holmium laser fiber is placed on the surface of the stone for fragmentation. Intra renal lithotripsy was carried out using a 30 W Holmium: YAG laser (Sphinx Jr.) via a 272 m silica quartz laser fiber. 1.9 Fr tipless nitinol baskets were finally used to remove the large fragments. A Double-J (6 Fr) stent is generally applied at the end of the procedure, and a urethral catheter was applied.
