Swelling after hydrocele surgery is expected and normally lasts for two to three weeks after surgery. Scrotal or penile swelling appears immediately or within the first week post surgery, Columbia University Medical Center states.
Hydrocele surgery corrects a painless swelling of the scrotum caused by a fluid-filled sac, MyHealthAlberta.ca explains. When a male has an opening between the belly and the scrotum, a hydrocele forms. Other side effects of hydrocele surgery include slow bowels and mild pain. It is important after surgery to maintain some light activity, such as walking, to help prevent deep vein thrombosis. To help with swelling, patients may apply ice packs in the first 24 hours after the procedure. Abnormal or longer-lasting swelling is reason to follow up with the surgical care provider.
