JNW UrTrac Sheath

The JNW UrTrac® (LSI Solutions, Victor, NY) is an endoscopic access sheath designed for endoscopic urethroplasty, specifically the transurethral incision with transverse mucosal realignment (TUITMR) technique for treating vesicourethral anastomotic stenosis and bladder neck contracture. The sheath provides the working channel through which sutures, knots, and imaging are delivered.

Design​

  • Rigid outer sheath for stable transurethral access
  • Obturator for atraumatic insertion past the sphincter complex
  • Shut-off valve on the working channel — allows rapid exchange of instruments without loss of irrigation or pneumoperitoneum
  • Accommodates a flexible digital ureteroscope for visualization alongside the RD180 suturing device and Ti-Knot fastener

Use in Endoscopic Urethroplasty​

In the TUITMR technique:

  1. JNW UrTrac is introduced with its obturator
  2. Once beyond the sphincter, the obturator is removed
  3. A shut-off valve is placed in the working channel
  4. A flexible digital ureteroscope advances through the valve into the bladder
  5. The UrTrac is then advanced into position
  6. RD180 suturing device is passed through the UrTrac to place sutures through scar tissue and healthy bladder mucosa
  7. Ti-Knot fasteners secure the sutures endoscopically

Clinical Context — TUITMR​

Transurethral Incision with Transverse Mucosal Realignment (TUITMR) is a 2021-described endoscopic alternative to robotic urethroplasty for post-prostatectomy vesicourethral anastomotic stenosis and bladder-neck contracture. The technique incises scar tissue and advances healthy bladder mucosa across the stenotic segment, secured with endoscopically-placed sutures and knot-free fasteners. Early single-center experience reports 89% success after one treatment and 100% after two, with no de novo incontinence.[1]

Platform​

The JNW UrTrac is part of an LSI Solutions ecosystem — the UrTrac provides access, the RD180 places sutures, the Ti-Knot (TK) secures them — designed to perform complete endoscopic urethroplasty without external abdominal or perineal incisions.
