Cystography showed a wide funnel-shaped BN, and cystoscopy showed enlarged BN with stiff tissue. Subsequent muscularis innervation of the urinary bladder trigone (MIUL) surgery was performed. 2.Patients who failed to treat urinary incontinence through other surgical methods and came to our hospital for reoperation, including those with a history of epispadias repair with urinary incontinence, erosion of urinary incontinence sling, and patients with paraurethral diverticulum and urinary incontinence complicated after male urethral repair. Subsequent MIUL surgery of the bladder trigone was also performed. 3.Other congenital or acquired urinary incontinence diseases, such as congenital female anorchia or short and wide urethra, congenital hypospadias, traumatic or iatrogenic acquired hypospadias, and urethral length less than 2 cm. Subsequent MIUL surgery of the bladder trigone was also performed.
