A rare retroperitoneal tumor obstructing the left ureter was surgically removed. The ureter was then successfully reconnected to a kidney via transureterocalicostomy, a novel surgical approach.

Area of Science:

  • Urology
  • Surgical Oncology

Background:

  • Retroperitoneal tumors can cause significant urinary tract obstruction.
  • Left ureteral obstruction by infiltrating tumors presents complex surgical challenges.

Observation:

  • A case involving an infiltrating retroperitoneal tumor encasing and obstructing the mid-left ureter.

Findings:

  • Surgical resection of the tumor and a 10 cm ureteral segment was performed.
  • Successful diversion of the upper left ureter to the right ectopic kidney's upper calix (transureterocalicostomy) was achieved.

Implications:

  • This case demonstrates the feasibility of transureterocalicostomy for complex ureteral reconstruction.
  • Highlights a potentially life-saving surgical option for rare retroperitoneal tumor complications.
