Retrospective analysis of the results of transurethral contact pyelocalycolithotripsy in patients with kidney stones

Abstract

Transurethral contact lithotripsy is a promising treatment method and occupies an important place among endoscopic methods for removing kidney stones.
 The aim of the study was to identify the advantages and disadvantages of transurethral contact pyelocalycolithotripsy in patients with kidney stones based on retrospective analysis.
 Material and methods. A retrospective analysis of 178 clinical cases of treating patients aged from 19 to 71 years who suffered from kidney stones and underwent transurethral contact pyelocalycolithotripsy was performed. All patients were diagnosed with calculi of the pyelocaliceal system with the diameter ranging from 10 to 20 mm according to multispiral CT data. Renal calculi had different composition and their density varied from 460 HU to 1440 HU. Pneumatic and laser energy was used for lithotripsy in 102 (57.3%) and 76 (42.7%) patients respectively.
 Results. The obtained data show that complete destruction of the stones and the removal of fragments within 2 weeks after transurethral contact pyelocalycolithotripsy was noted in 143 (80.3%) patients. In 140 (78.7%) cases positive results were achieved in one surgical intervention and in 38 (21.3%) patients after two procedures. Complications of this treatment method were relatively rare and included intraoperative bleeding, pelvic perforation, acute pyelonephritis, stent migration, postoperative bleeding, and residual stones.
 Conclusion. Transurethral contact pyelocalycolithotripsy is a promising method due to the fact that in most cases it allows you to simultaneously rid a patient of kidney stones with minimal complications
