With the technological advances in endourology, endoscopic treatments, including balloon dilation, cold knife incision, and laser endoureterotomy are also being used.
Of the eight patients treated with laser endoureterotomy, two required multiple endoscopic procedures, one had a subsequent nephrectomy, one had a subsequent ureteroureterostomy, and one had subsequent ureteral re-implant.
Also, endoureterotomy has been shown to be less successful in this cohort of patients and consideration for more definitive open surgical reconstruction is suggested from the onset of presentation.
With advancements in endourologic instrumentation, Ho:YAG laser endoureterotomy is a popular choice.
All eight patients undergoing endoureterotomy in our case series were treated with Ho:YAG laser.
Unfortunately, she had ongoing severe flank pain and, despite periodic imaging and bloodwork showing stable hydronephrosis and renal function, her kidney atrophied one year post-laser endoureterotomy and she subsequently received laparoscopic nephrectomy.
