Is flexible navigable suction ureteral access sheath (FANS) safer and more efficient than conventional sheaths? Italian multicentric experience.

Background And Objective: The flexible and navigable suction ureteral access sheath (FANS) with continuous flow lithotripsy may improve stone-free rates (SFR) in ureterorenolithotripsy procedures, reducing operative time and the need for fragment extraction. This study aimed to compare the safety and efficacy of FANS versus conventional sheaths in patients undergoing retrograde intrarenal surgery (RIRS) for renal stones.

Methods: From January to September 2024, patients undergoing RIRS with high-power pulsed lasers (60 W Ho:YAG or 100 W pTm:YAG) were randomized to receive either a conventional sheath (Group 1) or FANS (Group 2).

[Ductal carcinoma of the prostate: impact on survival and therapeutic controversies of a rare tumor].

Prostate cancer is a disease with a variable clinical course. The possible impact on oncological outcome of non-acinar prostate cancer has not been established yet, especially for ductal adenocarcinoma due to its low frequency, so that its clinical management is not well codified. The disease occurs more often already at an advanced stage of diagnosis, with clinically detectable tumors and advanced pathological stage, partly because of the lack of specific tumor markers, given the poor correlation between PDA and PSA values.
