Abstract
Objective To explore the clinical causes and preventive measures of complicating ascites of mini-percutaneous nephrolithotripsy (MPCNL).Methods Retrospective analysis of 285 patients with MPCNL for upper urinary tract calculus,which were divided into ascites group and no-ascites group.Results All the procedures were successful.Ascites group of 21 cases,no-ascites group of 264 cases.Univariate analysis showed that the diameter and number of calculus,perfusion pressure,perfusion time,pressure volume of irrigation fluid,preoperative upper urinary tract infection,history of treatment associated with complicating ascites (P＜ 0.05),with age,gender,body mass index no correlation (P＞ 0.05).Logistic regression analysis showed that perfusion pressure,perfusion time,pressure volume of irrigation fluid was independent risk factors after MPCNL concurrent ascites (P ＜ 0.05).Conclusions MPCNL concurrent ascites are closely related to the large perfusion volume,the long operative perfusion time,the high perfusion pressure of irrigation fluid.On the premise of keeping the operative visual field clear,as far as possible to reduce the perfusion pressure,control irrigation fluid-flow rate,reduce the large peffusion volume.These could decrease the coincidence of the ascites.
