Abstract

The objective of this study was to describe certain clinical and paraclinical characteristics of patients who developed hemorrhagic complications after mini-percutaneous nephrolithotomy (mini-PCNL), to evaluate treatment outcomes of these complications at Hanoi Medical University Hospital, and to identify potential risk factors associated with hemorrhage requiring selective renal arterial embolization. We conducted a retrospective descriptive study including 131 patients diagnosed with post-mini-PCNL bleeding between January 2019 and June 2024. The mean age of the patients was 53.2 ± 10.1 years. The mean interval from mini-PCNL to the onset of bleeding was 6.08 ± 5.28 days. The most common clinical presentation was gross hematuria (80.2%), followed by bleeding through the nephrostomy tube (49.1%), flank pain (30.5%), urinary retention after foley catheter removal (12.9%), bleeding from the nephrostomy tract after tube removal (12.9%), and hemorrhagic shock in three patients (2.5%). The mean hemoglobin drop was 14.9 ± 11.2 g/l, and 7.6% of patients required blood transfusion. Conservative treatment was successful in 98 patients (74.8%), while 33 patients (25.2%) required selective renal arterial embolization; no patient required reoperation for hemostasis or nephrectomy. Multivariate analysis indicates that diabetes mellitus is an independent risk factor for bleeding requiring embolization after mini-PCNL.
