Equally with increasing role of extracorporeal impulse lithotripsy (EIL) as the most progressive method of uroliths elimination, there is a growing usage of x-ray endoscopy which raises EIL efficacy, helps to prevent its complications and side effects, serves a good adjuvant and preventive tool. A nonrandomized [correction of randomized] trial of 2000 consecutive sessions of EIL in 1311 patients with various forms of urolithiasis provided evidence for detailing indications for such methods of supravesical endourology as catheterization and stenting of the upper urinary tracts, transcutaneous puncture nephrostomy, percutaneous and transurethral roentgenoendoscopic surgery of nephroliths and ureteroliths. Combined application of EIL and supravesical endourological techniques allows elimination of the stones without surgical interventions in complicated urolithiasis in patients with stag-horn calculi, multiple and large ones, with calculi of anomalous and floating kidney, etc. The need in x-ray endoscopy is also dictated by EIL contraindications and high efficacy of the x-ray endoscopy operations. The experience gained in the Research Urological Institute as regards surgical, endoscopic and EIL treatments of urolithiasis provided the material for design of algorithms to be adopted in the choice of therapeutic policy in ureteroliths and coral renal calculi.
