Temperature changes during laser lithotripsy with Ho:YAG laser and novel Tm-fiber laser: a comparative in-vitro study.

Aim: The aim of this study was to compare the thermal effects of Ho:YAG and Tm-fiber lasers during lithotripsy in an in-vitro model via real-time temperature measurement.

Methods: We compared a Ho:YAG laser (p up to 100 W, Lumenis, Yokneam, Israel) and a superpulse Tm-fiber laser (SP TFL, p up to 40 W, NTO IRE-Polus, Fryazino, Russia), both equipped with 200 µm bare-ended fibers. The following settings were used: 0.

Extracorporeal ureter handling during laparoscopic pyeloplasty: tips and tricks for beginners.

Introduction: Laparoscopic preparation of the ureter is a challenging part of upper urinary tract reconstruction, due to limited depth perception provided by the camera and lack of wristed motion of most laparoscopic instruments needed for adequate spatulation and scar tissue removal. One solution has been to perform the more difficult portions of the surgery in an extracorporeal manner. A hybrid intracorporeal-extracorporeal approach to upper tract ureteral reconstruction facilitates ureteral preparation at the stage of mastering the technique.

[Aberrant expression of arrestin-1 and recoverin in kidney tumors].

Introduction: Early diagnosis of renal cell carcinoma (RCC) is extremely difficult, due to the late development of clinical manifestations. The study of the aberrant expression of tumor-associated antigens and a production of autoantibodies to these proteins seems promising and novel method for RCC diagnosis.

Aim: To evaluate the possibility of using arrestin-1 (Arr-1), recoverin (Rec) and autoantibodies against arrestin-1 (AAA1) and recoverin (AAR) as a kidney tumor biomarker.

[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.
