Haygrove Sound

The semicircular Haygrove sound is designed specifically for posterior urethroplasty.

Design — Semicircular Profile​

Unlike the Van Buren (which curves only at its tip), the Haygrove's full-length semicircular profile follows the natural path from the suprapubic cystotomy down to the membranous urethra in a patient positioned in exaggerated lithotomy.

This matters because posterior urethroplasty is performed from below (the perineum) while an antegrade sound is passed from above (through a suprapubic cystotomy). The Haygrove's curve matches the trajectory a sound must take from the bladder neck, through the proximal urethra, and out toward the operating surgeon in the perineum. A Van Buren's tip-only curve binds at the pubic arch; the Haygrove glides through.

Key Uses​

  • Posterior urethroplasty — cannulate the proximal urethral stump through the bladder neck
  • Define the normal proximal urethral caliber
  • Serve as an intraoperative locator for the anastomotic target
  • Tent the proximal urethra toward the surgeon during anastomosis
