Study of urological devices coated with fullerene-like nanoparticles.

Insertion of endoscopes and other medical devices into the human body are ubiquitous, especially among aged males. The applied force for the insertion/extraction of the device from the urethra must overcome endoscope-surface-human-tissue interactions. In daily practice a gel is applied on the endoscope surface, in order to facilitate its entry into the urethra, providing also for local anesthesia.

Filling cystoureterography facilitates stone visualization in patients with previously inserted double-J ureteral stents.

In our study, we assessed the ability of a filling cystogram to induce vesicoureteral reflux (VUR) and to evaluate its role in stone targeting during ESWL in the presence of a double-J ureteral stent (JJ-S). Filling cystoureterography was performed during ESWL in 17 patients with previously inserted 4.7 F JJ-S.

Laparoscopic laser soldering for repair of ureteropelvic junction obstruction in the porcine model.

Background And Purpose: Laparoscopic pyeloplasty is used for the repair of ureteropelvic junction (UPJ) obstruction. Our objective was to introduce laser soldering to this procedure.

Materials And Methods: We developed a system based on a CO2 laser, an infrared detector, and two infrared transmitting optical fibers to obtain temperature-controlled laser soldering of cuts in tissues.
