Quality of life with tandem ureteral stents compared to percutaneous nephrostomy for malignant ureteral obstruction

Abstract

Purpose: Malignant ureteral obstruction (MUO) is treated with kidney decompression by a percutaneous nephrostomy (PCN) or internal ureteral stents. The objective of this study was to compare quality of life (QoL) with a PCN compared to tandem ureteral stents (TUS) in cases of MUO.

Methods: We reviewed the medical records of patients with MUO who were treated by PCN/TUS in our institution between June 2019 and May 2020. Patients were asked to fill out a QoL questionnaire, a tube-symptoms questionnaire, report a general health scale, and asked for a drain preference if they had experience with both drains. Scores of both groups were compared and predictors of all QoL and tube-symptoms measures were searched using multivariate analysis.

Results: Seventy-four patients with a PCN and 30 with TUS were included in the study. No statistically significant difference was found in all QoL and tube-symptoms measurements between the two drains. Type of drain was not found to be a predictor of QoL or tube-related symptoms. Eighty-four percent of patients (11/13) who have experience with both types of drains preferred TUS.

Conclusion: TUS and PCN for relief of MUO have a negative and similar effect on various areas of QoL and urinary symptoms. Most patients who had experience with both types of drains preferred TUS over PCN. In this patient population with a grim prognosis, this negative effect must be communicated to patients, and calculated against the potential benefits of drainage.
