Ultrasonic renal lithotripsy. Single-stage percutaneous technique and adjuvant radiological procedures.

Abstract

Single-stage percutaneous ultrasonic disintegration and removal of renal calculi was attempted in 67 patients (80 calculi) and proved successful in 65 (97%). Extraction was achieved during the initial session in 52 patients (78%) and required either an adjuvant radiological procedure or repeat nephroscopy in 13. Single-stage removal combines the skills of the radiologist and urologist and is successful in the majority of cases.

Upper ureteral calculi: extraction via percutaneous nephrostomy

“…In our institution, percutaneous nephrostolithotomy is done as a single-stage procedure in over 90% of cases [3]. After induction of general anesthesia (used for 95% of cases), cystoscopy is done by the urologist, and a retrograde ureteral catheter is placed for distending and opacifying the collecting system with dilute contrast material to facilitate the percutaneous nephrostomy.…”

Staghorn Calculi: Percutaneous versus Anatrophic Nephrolithotomy

“…Surgical removal of renal calculi is an essential ele ment in the successful management of patients with cal culous disease [1,10], Although numerous reports have been published describing various techniques to treat staghorn calculi, anatrophic nephrolithotomy techniques in renal ischemia and hypothermia are generally associ ated with better results in the management of this dis ease [2][3][4].…”

“…Several methods for removing renal stones are available, but ultrasonic litho tripsy is in general considered the most effective tech nique for most renal calculi [4,14,19], So far only limited data comparing the efficacy of the two methods for treating renal staghorn stones have been published.…”
