A novel transmesosigmoid cutaneous ureterostomy technique creates a single stoma for urinary diversion. This method effectively manages ureters, even short ones, offering a catheterless solution for patients requiring supravesical diversion.

Area of Science:

  • Urology
  • Surgical Innovation
  • Medical Device Development

Background:

  • A new surgical technique for single-stoma cutaneous ureterostomy was developed.
  • This method utilizes the mesosigmoid to buttress and cover the ureters within the abdominal cavity.

Purpose of the Study:

  • To describe a novel transmesosigmoid cutaneous ureterostomy technique.
  • To evaluate the efficacy and outcomes of this single-stoma urinary diversion method.

Main Methods:

  • Utilized the long mesenterium of the sigmoid colon for the bilateral ureteral pathway.
  • Created retroperitoneal tunnels for ureters, brought them to the mesocolonic junction, and sutured the junction to the abdominal wall.
  • Conjoined and exteriorized ureters through a V-skin flap on eight high-risk patients with incurable bladder tumors.

Main Results:

  • One patient required catheter indwelling due to low urinary output; others were managed catheter-free.
  • Postoperative complications included paralytic ileus in three patients and mechanical ileus requiring laparotomy in one.
  • Follow-up excretory urography showed normal upper urinary tracts in 11 kidneys and mild hydronephrosis in three.

Conclusions:

  • Transmesosigmoid cutaneous ureterostomy offers a single, catheterless stoma for urinary diversion, even with short ureters.
  • This technique appears to be a viable option for supravesical urinary diversion when indicated.
