It has been 20 days since hypospadias operation. Can I wear underwear?

Of course. The wound should be kept dry after hypospadias operation. The urinary catheter is usually reserved after operation, which plays the role of draining urine and supporting urethra to prevent urethral stricture and prevent the repaired urethra from being wetted by urine. Exercise should be properly fixed to prevent the catheter from coming out, and the catheter should not be pulled out at will. After the catheter is removed, the body is in the recovery period, so special attention should be paid to keeping the perineum warm to prevent dysuria caused by contraction of the skin flap. Take a bath every day, change your underwear frequently, and keep your perineum and genitals clean.
