Clinical analysis of ultrasound-guided "tract without bleeding vessel requiring embolization (TBVE)" in reducing bleeding during percutaneous nephrolithotomy.

ABSTRACT:

Objective

To compare the efficacy of ultrasound-guided tract without bleeding vessel requiring embolization (TBVE) versus conventional minimally invasive access in mini-percutaneous nephrolithotomy (Mini-PCNL) for reducing postoperative bleeding.

Methods

This retrospective study analyzed 188 patients who underwent Mini-PCNL by a single surgeon between June 2021 and July 2023. Patients scheduled for mini-PCNL were assigned to two groups based on access technique. The first group had no TBVE (Standard mini-PCNL, n = 95) and the second group had TBVE (TBVE-assisted Standard mini-PCNL, n = 93). Baseline characteristics-including gender, age, body mass index (BMI), stone location, stone size, and preoperative hemoglobin levels-were balanced (P > 0.05). Perioperative outcomes were
