A prostate morcellator device (PMD) effectively manages organized bladder blood clots after laser prostatectomy. This safe and well-tolerated technique provides a solution for difficult clot evacuations, improving patient outcomes.

Area of Science:

  • Urology
  • Surgical Technology

Background:

  • Benign prostatic hypertrophy (BPH) often requires surgical endoscopic management.
  • Laser prostatectomy can lead to complications such as hematuria and organized bladder blood clots.
  • Evacuating organized bladder blood clots can be challenging with conventional methods.

Purpose of the Study:

  • To provide a technical update on using a prostate morcellator device (PMD) for managing organized bladder blood clots.
  • To describe the experience with the Wolf Piranha morcellator in this specific clinical scenario.

Main Methods:

  • Retrospective chart review of patients undergoing PMD for bladder clot management.
  • Utilized the Wolf Piranha morcellator device.
  • Compared PMD outcomes with prior conservative management attempts.

Main Results:

  • Six male patients (mean age 75 ± 8.9 years) with organized bladder clots post-laser prostatectomy were treated.
  • Mean morcellation time was 10.2 ± 6.15 minutes for clots averaging 173.3 ± 115.9 cc.
  • The procedure was well-tolerated with no intraoperative or device-related complications.

Conclusions:

  • Organized bladder blood clots following laser prostatectomy can cause urinary retention and are difficult to evacuate.
  • The Wolf Piranha PMD is a safe, well-tolerated, and effective tool for managing these organized clots.
  • PMD offers a viable solution for challenging bladder clot evacuations in BPH patients.
