Penile folding surgery refers to penile sponge folding, which is used to treat urinary incontinence due to urethral sphincter dysfunction. Penile sponge folding surgery begins with an incision to visualize the spongy volume of the urethral bulb, followed by freeing the urethra from the perineum and bulb, making an incision between the penile sponges, burying the free urethra between the right and left penile sponges, and suturing. There are contraindications to penile folding surgery, and this procedure cannot be performed in the presence of filling incontinence due to bladder outlet obstruction, nor can it be performed in the case of cystitis incontinence or in combination with bladder outlet obstruction. Before penile folding surgery, it is recommended to have a detailed examination, if it meets the indications for the surgery before proceeding with the surgery, after the surgery, it is necessary to keep a urinary catheter for a period of time, and every six months after the surgery, it is necessary to follow up the patient.
