Abstract:
Objective To investige the risk factors of urosepsis after percutaneous nephrolithotomy (PCNL).Methods We retrospectively analyzed 204 renal calculi or proximally ureter calcui patients,who underwent ultrasound-guided PCNL,from January 2013 to January 2014.Among them,there were 140 men and 64 women,whose mean age was 49 years (range from 29 to 75 years).Eighty-four operations were performed via standard channel and 120 operations were performed via micro channels.Fifty one patients had staghorn stones.Before operation,the urine culture positive rate was 14.7% (30/204).The creatinine level ranged from 46 to 340 μmol/L [mean (87.9±33.9) μmol/L].Average stone diameter was (2.3±0.8) cm (range 1.0-7.0 cm).Mean operative time was (68.4±26.9) min (range 23-219 min).The chi-square test and a logistic regression model were used to identify key risk factors.Results The operation duration ranged from 23 to 219 min,mean (68.4±26.9) min.Of 204 patients,9 (4.4%) suffered septic shock,including 7 female patients and 2 male patients.Their mean age was (52.6± 15.2) years (20-73 years).Five operations were performed via standard channels and four operations were performed via micro channels.Five patients had staghorn stones.Urine culture positive rate was 77.8% (7/9).The average stone diameter was (2.5±0.6) cm (range 1.8-3.5 cm).Mean operative time was (86±53) min (range 47-219 min).In univariate analysis,significant associations was observed between female gender (P =0.005),positive urine culture (P<0.01),staghorn calculi (P =0.035),operative duration>90 min (P =0.042) and sepsis after PCNL.While in multivariate analysis,female gender (OR=6.001,95%CI=1.190-30.276,P=0.03) and positive urine culture pre-operation (OR=19.647,95%CI=3.918-98.562,P<0.01) were identified as independent risk factors for post-MPCNL septic shock.Conclusions Female gender and positive urine culture before operation are the key risk factors of urosepsis after percutaneous nephrolithotomy.
