[FLEXIBLE NEPHSCOPY AND NEPHROLITOEXTRACTION IN A GASEOUS MEDIUM (CO2) IN A PATIENT WITH RESIDUAL CALCULI OF THE RIGHT KIDNEY].

Flexible endoscopy is an integral part of modern endourology. However, the use of flexible endoscopes in a liquid medium predispose to some difficulties and disadvantages of this technique. This article presents a clinical observation of use of a flexible nephroscope for extraction of residual calculi in a gaseous medium (CO2) in a patient with residual calculi of the right kidney.

[TRANSURETHRAL CONTACT URETERAL LITHOTRIPSY IN A GASEOUS (CO2) MEDIUM].

The paper describes for the first time the method of contact ureteral lithotripsy in gaseous (CO2) medium. It presents the results of a comparative study of urolithiasis patients treated with this treatment modality (study group, n=30) and with traditional contact ureteral lithotripsy in liquid medium (control group, n=30). The incidence of retrograde migration of calculus in the kidney in the study group was 0%, while it was 16.
