The primary role of scrotal support after hydrocelectomy is to reduce postoperative swelling by minimizing dependent edema and providing gentle compression. This support helps limit fluid accumulation in the scrotal tissues, thereby promoting comfort and faster resolution of inflammation. Additionally, it stabilizes the surgical site, reducing mechanical stress on sutures and aiding in optimal wound healing. Preventing excessive swelling also decreases the risk of complications such as hematoma formation. Thus, scrotal support is a key postoperative measure to enhance recovery by controlling edema rather than preventing infection or improving mobility or fertility.
