Purpose: To evaluate the safety and efficacy of desmopressin (DDAVP) administration prior to NFRB to mitigate bleeding risk.

Materials and Methods: This retrospective observational study included all 158 patients who underwent NFRB from 3/2022—6/2025, before and after implementation of a DDAVP administration protocol. In 7/2023, every patient regardless of renal function received 0.3 mcg/kg intravenous DDAVP immediately before biopsy, involving 18-gauge cores through coaxial guides. Patients who did or did not receive DDAVP were compared using Mann-Whitney U tests for nonparametric data, Student’s t tests for parametric data, and chi-square tests for categorical data, (alpha level of P< 0.05).

Results: Of 158 patients, 79 received DDAVP and 79 did not. Sodium was not significantly different at pre- or post-procedure, p = 0.61 and 0.45, respectively. Hemoglobin values were not different pre procedure and with fewer post procedure values the difference pre to post was not significant. Blood transfusion rate (10.1%) was the same for both groups. Six/79 (8%) patients who underwent NFRB without DDAVP had an unplanned admission and/or angiography within 1 week of biopsy, compared to 0 in the DDAVP group (P=0.03). There was no difference in the rate of thromboembolic events between groups (2/79 [2.5%] v. 3/79 [3.8%]; P=1.00). All 5/158 (3.2%) patients who had stroke or a myocardial infarction within 1 week of NFRB had been on anticoagulant or antiplatelet agents that were held for biopsy.

Conclusion: DDAVP was associated with reduced unplanned hospitalizations and angiography/embolization after NFRB without increasing the risk of thromboembolic events.
