Introducton: The repair of large urethrocutaneous fistulas (UCFs) commonly involves reconstruction of the urethra, waterproof layer and skin coverage, which deploy different tissues from different flaps. To simplify the multiple procedures, we explored to use one flap (a scrotal-septal flap) to reconstruct three layers in UCF repairing in one stage.
Methods: Between January 2011 and July 2012, 29 patients with large UCFs (ranging from 1.0 to 2.0 cm) were treated using scrotal-septal flaps for three-layer reconstruction. Every patient has an unbroken scrotum. The hair follicles in the donor site were destroyed using a radiosurgical knife 2 months before the operation. The flap was divided into three zones, which were flipped, folded, and extended respectively to form the urethra, waterproof layer and skin coverage.
Results: The patients were followed up between 6 to 12 months. No fistula recurrence was observed. All flaps survived, except in one case, in which the distal skin flap was lost but stenosis or fistula did not develop. Two patients underwent second operations to refine the aesthetic results.
Conclusions: The scrotal-septal flap can be transferred in an overturning-folding-advancement fashion and can simultaneously involve the reconstruction of the urethra, waterproof barrier and skin coverage. This is a simple and reliable alternative for large UCFs (≤2 cm) repairing at the penoscrotal junction; however, it cannot be used in patients with a damaged scrotal septum.

Urethrovaginal fistulas are rare complications often arising from urethrovaginal injuries commonly due to obstetrical trauma, urethral surgeries, pelvic fractures, or neoplastic treatments. Here, we present a unique case involving a 23-year-old female patient with a large urethrovaginal fistula and complete anterior vaginal wall sloughing following prolonged obstructed labor. Nine months post-cesarean, she reported urine leakage via the vagina upon catheter removal, which intensified in an erect posture.

Background: Hypospadias was ranked second after undescended testis as the most prevalent congenital abnormality in newborn males. Hypospadias can be successfully repaired through multiple surgeries in the majority of children. Postoperative complications were not rarely seen after surgeries, such as urethrocutaneous fistula (UCF), meatal stenosis, and glans breakdown.

Accurate measurement of urinary parameters in awake mice is crucial for understanding lower urinary tract (LUT) dysfunction, particularly in conditions like neurogenic bladder post-traumatic spinal cord injury (SCI). However, conducting cystometry recordings in mice presents notable challenges. When mice are in a prone and restricted position during recording sessions, urine tends to be absorbed by the fur and skin, leading to an underestimation of voided volume (VV).

Article Synopsis
- A clinical classification system for urethrocutaneous fistulas (UCFs) was developed to help surgeons categorize different types of fistulas, choose appropriate treatments, and manage patient records effectively.
- The study analyzed data from 68 patients treated for UCFs between 2004 and 2016, classifying the fistulas into several categories (A to E) based on their characteristics and complexity, which influenced the treatment approach.
- Results showed that most patients did not experience recurrence of fistulas after treatment, supporting the utility of the classification system in guiding effective management of UCFs.
