Effect analysis of percutaneous nephrolithotomy in the treatment of kidney stones with different degrees of renal sinus separation
Objective To investigate the effect of percutaneous nephrolithotomy(PCNL)on the treatment of renal stones with different degrees of renal sinus separation and the influencing factors of complications.Methods The clinical data of 167 patients with kidney stones tract stones admitted to 909th Hospital of the Joint Logistic Support Force from January 2019 to December 2021 were retro-spectively analyzed.All patients were treated with PCNL.According to preoperative color ultrasound,the patients were divided into group A(53 cases),group B(63 cases)and group C(51 cases).The operation time,intraoperative blood loss,hemoglobin decline on the first day after surgery,length of hospital stay and incidence of complications in the three groups were analyzed,and the influencing fac-tors of postoperative complications were analyzed by univariate and logistic multivariate factors.Results The operative time,intraoperative blood loss and the decrease of hemoglobin on the first day after sur-gery in group A were higher than those in group B and group C,while the intraoperative blood loss in group B was higher than that in group C(all P<0.05).The incidence of severe hematuria and sub-capsular hematoma in group A was higher than that in group B and group C,and the differences were statistically significant(all P<0.05).Multivariate logistic analysis showed that body mass index(BMI),maximum stone diameter,operation time,intraoperative blood loss and renal sinus separation were independent influencing factors for postoperative complications of PCNL(all P<0.05).Conclusions The incidence of hemorrhage after PCNL is high in patients with renal calculus with small renal sinus separation degree.Meanwhile,BMI,stone size,operation time,intraoperative blood loss and renal sinus separation degree are independent factors influencing the occurrence of postoperative complications of PCNL,which has guiding significance for clinical practice.
