In urology, Arista is applied in which procedure?

• A. Prostatectomy
• B. Cystectomy
• C. TURP
• D. Ureteral Stenting

Answer: (A)

Arista AH is a gelatin-based, absorbable hemostatic sponge placed directly on a bleeding surface to rapidly promote clot formation. In a prostatectomy, the prostatic bed and surrounding venous plexus bleed diffusely after gland removal. Applying Arista provides a physical scaffold for platelets and coagulation factors, helping to tamponade oozing from the raw prostatic tissue and vessels. It helps achieve hemostasis without extensive cautery and is later absorbed, reducing the need for persistent pressure or suturing. In contrast, procedures like TURP rely more on cautery and irrigation for control of bleeding, and while other surgeries can use hemostatics, the prostatic bed after prostatectomy is a classic scenario where Arista is especially advantageous.
