Edema of the penis and scrotum will be swollen in appearance, or one side of the scrotum is larger than the other, inconvenient and easily injured, sometimes combined with a painful sensation of swelling, and may even affect the blood circulation of the testicles due to excessive accumulation of water, which will cause testicular atrophy over time and affect the ability of the testicles to produce sperm in the future, resulting in infertility. Patients should go to the hospital for systematic examination and treatment as soon as they find edema in the penis and scrotum.

Surgery: In children, the sheath of the scrotum is ligated by surgically entering through the groin, and the fluid is extracted and removed distally. In adults, if the hydrocele is simple, the scrotum can be excised by cutting through the scrotum. Extraction of hydrocele: Some people have also been treated with sclerotherapy after aspiration, but it is not effective and is prone to recurrence and inflammation, so it should be chosen carefully. Especially in children more inappropriate, because the inguinal sphincter is not completely closed, can cause peritonitis. Preventive care: 1. Position: scrotal wall is thin and tense when edema is present, it needs to be held up with both hands or scrotal brace should be applied when walking up, the action should be gentle when placing the scrotal brace and the tightness should be appropriate. 2. Local care: keep the scrotal skin clean and dry, wash with warm water or replace the urine bag in time after urination to reduce urine stimulation. Keep the bed sheets clean, and wear soft, sweat-absorbing silk and cotton pajamas. 3, diet care: elderly patients generally have decreased liver and kidney function, abnormal glucose metabolism, electrolyte disorders. Therefore, nutritional treatment and care are especially important. Both electrolytes should be replenished and water intake should be controlled.
