Application of Multi-Slice Spiral CT Renal Angiography Combined with Intraoperative Ultrasound in Laparoscopic Partial Nephrectomy.

Abstract

This study aimed to evaluate the clinical significance of multi-slice spiral CT renal angiography combined with intraoperative ultrasound in laparoscopic partial nephrectomy. Eighty patients were seen at the Affiliated Hospital of Hebei University from January 2021 to December 2022. The patients were divided into two groups, the experimental group and the control group, with 40 cases in each group. The experimental group received laparoscopic partial nephrectomy combined with intraoperative ultrasound, while the control group received only conventional laparoscopic partial nephrectomy. The experimental group had significantly shorter operative time and intraoperative thermal ischaemia time (p <0.05) and had significant advantage in the detection of microscopic cancer foci (p = 0.04). The experimental group also had significantly lower of positive rate of postoperative incisal margin (p = 0.01). The experimental group had significantly lower of recurrence rate (p = 0.03). The study concluded that multi-slice spiral CT renal angiography combined with intraoperative ultrasound boasts various benefits in the treatment of patients with renal cell carcinoma, it is safe and effective with no significant impact on renal function.
