ABSTRACT
Objective To explore the effect of infrared spectral analysis in analyzing of the chemical composition of renal staghorn calculi and its relationship with urinary tract infections. Methods From June 2014 to June 2016, the clinical data of 186 patients with renal staghorn calculi were collected. The stone composition were analyzed by infrared spectroscopy and traditional chemical titration, and the stones infection were detected by microbial analysis system. The relation between stones infection, urinary tract infection and stone composition were analyzed. Results The results of infrared spectroscopy and traditional chemical titration in detecting renal staghorn calculi ingredient had no significant differences (P>0.05). In 186 patients, 56 patients (30.11%) was in infected group, and 130 patients (69.89%)was in non-infected group. The abnormal urine rate, urinary tract infection rate, medistream urine positive infection rate and cotton swabs positive infection rate in infected group were was significantly higher than those in non-infected group: 73.21%(41/56) vs. 50.77%(66/130), 19.64%(11/56) vs. 3.85%(5/130), 50.00%(28/56) vs. 6.15%(8/130), 67.86%(38/56) vs. 8.46%(11/130), P<0.01. The carbonate apatite stones rate and six water magnesium ammonium phosphate rate in infected group were significantly higher than those in non-infected group: 21.43%(12/56) vs. 5.37%(7/130), 57.14%(32/56) vs. 2.31%(3/130), P<0.01. The calcium oxalate rate and uric acid rate in non-infected group were significantly higher than those in infected group:50.00%(65/130) vs. 5.36%(3/56), 24.62%(32/130) vs. 1.79%(1/56), P<0.01. Conclusions Analysis of staghorn calculi ingredient caused by urinary bacterial infection with infrared spectroscopy is simple, reliable and easy to operate. It is important for postoperative infection prevention.
