Purpose:

Nephrostomy tube dislodgements (NTD) burden both the patients and healthcare system through increased hospital admissions and cost. Determining whether patient demographics and placement etiology affect time to dislodgement (TTD) of nephrostomy tubes may help in identifying higher risk patients and identify targets for prevention.

Materials and Methods:

A retrospective review of NTD between February 2019 and June 2022 at an academic teaching hospital was performed. Data was collected for etiology of initial placement, TTD, body mass index (BMI), and ambulatory status (ambulatory without aid, ambulatory with cane/walker, or wheelchair dependent). Patients were grouped into BMI cohorts including < 18.5, 18.5 - 24.9, 25-29.9, and > 30. Categorical variables were compared using ANOVA and subsequent post-hoc tests using SPSS and Microsoft excel.

Results:

The final cohort consisted of 115 patients (median age 55 years, 49% male). Ambulatory status was as follows: 39 (34%) ambulatory without aid, 20 (17%) ambulatory with cane/walker, and 56 (49%) wheelchair dependent. Patients with BMI < 18.5 represented 14% (n=16) of the cohort, 18.5-24.9 was 30% (n=34), 25-29.9 was 21% (n=24), and > 30 was 30% (n=34). There was no significant difference in TTD across difference ambulatory statuses (P = .356) or BMI (P = .514). There was a significant difference in TTD when compared by indication for original tube placement (autonomic, cancer, obstruction, ureteral) (P = .039).

Conclusion:

Body habitus and patient ambulatory status were not found to be associated with a decreased time to NTD, suggesting that NTD may occur independently of factors inherent to the patient.
