Abstract
Objective?To study the risk factors of bleeding in percutaneous nephrolithotomy.?Methods?330 patients with renal calculi from February 2015 to February 2017 were selected as the research subjects. All the patients were treated by percutaneous nephrolithotomy. According to the occurrence of bleeding, the patients were divided into bleeding group and nonbleeding group. The clinical and surgical data of the two groups such as age, gender, body mass index, complications, type of calculi, diameter of calculi, staging surgery, surgical time, puncture path, number of channels, degree of hydronephrosis and history of surgery were collected.?Results?Among the 330 patients, there were 28 patients with bleeding after surgery, and the bleeding rate was 8.5% (28/330). There was no significant difference between the bleeding group and the non-bleeding group in age, gender, body mass index, being complicated with hypertension, abnormal liver function, staging surgery, puncture path or history of surgery (P > 0.05). The proportions of patients with diabetes mellitus, patients with staghorn calculi, patients whose calculi were or larger than 2 cm, patients whose surgical time was longer than 60 min, patients with multiple channels and patients without or with mild hydronephrosis in bleeding group were significantly higher than those in nonbleeding group (P < 0.05).?Conclusion?Diabetes mellitus, type of calculi, diameter of calculi, surgical time, number of channels and degree of hydronephrosis obviously influence the occurrence of bleeding after percutaneous nephrolithotomy. The type of stones, diameter of stones, operative time and number of channels were independent influencing factors of PCNL with bleeding.关键词
