Design: This is a case report of a 15-year-old patient who underwent successful placement of a single-incision mini sling. She was followed up outpatient at 3- and 6-month post-op visits.

Setting: At time of surgery, the patient was placed in dorsal lithotomy position under general anesthesia.

Patients or Participants: The patient is a 15-year-old nulligravid female with a history of insensible and continuous urinary incontinence. The patient has a BMI of 35 with no other past medical history and no neurological disease or spinal cord injury. Physical examination was benign. The patient underwent a tampon dye test and CT urogram, which were both negative for a fistula. No urethral abnormality was noted on CT scan. The patient underwent a multi-channel urodynamics study, which revealed a mean maximal urethral closure pressure of only 1 cm H₂O, indicative of complete intrinsic sphincter deficiency. Due to the age of the patient, conservative treatment options were initially pursued, however this only achieved transient resolution for the patient.

Interventions: After extensive counseling with the patient and her mother, the patient opted for definitive treatment with the placement of a mid-urethral sling. The patient underwent uncomplicated placement of a single-incision mini-sling and cystoscopy under general anesthesia.

Measurements and Main Results: At a 3 and 6-month postoperative follow-up, the patient reported a subjective cure of stress urinary incontinence.

Conclusion: Single incision mini-sling is a minimally invasive technique that may be a feasible treatment option to reduce urinary incontinence in pediatric patients with a diagnosis of intrinsic sphincter deficiency.
