Summary
Extra-anatomic stents (EAS) successfully diverted urine in all patients with ureteric obstruction due to malignancy. This technique offers an alternative to permanent nephrostomy for select patients.
Area of Science:
- Urology
- Oncology
Background:
- Ureteric obstruction secondary to malignancy often requires urinary diversion.
- Traditional methods like permanent nephrostomy have associated complications.
Purpose of the Study:
- To evaluate the efficacy of extra-anatomic stents (EAS) for urinary diversion.
- To assess EAS as an alternative in patients with malignancy-induced ureteric obstruction.
Main Methods:
- Retrospective analysis of 13 patients treated with EAS for ureteric obstruction.
- Patients presented with hydronephrosis and/or renal impairment due to advanced malignancy.
Main Results:
- Successful urinary diversion achieved in all 13 patients.
- Two patients survived over 1 year with regular stent changes.
- Three patients required conversion to percutaneous nephrostomy due to complications.
Conclusions:
- Extra-anatomic stents (EAS) are a viable therapeutic option for urinary diversion in select patients with ureteric obstruction.
- EAS provide an alternative to permanent nephrostomy, particularly for those unfit for invasive surgery.
- Careful patient selection is crucial due to potential complications associated with EAS.
