EVALUATION OF URINARY TRACT INFECTION FROM TESTING RENAL PELVIC URINE SAMPLES DONE BY PERCUTANEOUS NEPHROLITHOTOMY

Abstract

Objective: Evaluating renal pelvis urine samples during surgery provides valuable information about bacteriology, supports the treatment of urinary tract infections, and minimizes serious complications such as sepsis and septic shock. The objective of this research is to determine the rate of urinary tract infection in renal pelvic urine samples, the rate of sepsis and septic shock after percutaneous nephrolithotomy as well as to examine the type of isolated bacteria in renal pelvic urine samples and their antibiogram.

Methods: A total of 69 patients that met the criteria were retrospective studied. All patients had renal pelvic urine samples collected at 2 time points: puncturing and after lithotripsy approximately 15 to 30 minutes. These urine samples were evaluated by urinalysis, gram stain, culture and antibiogram. In addition, pre-, intra-, and post-operative variables related to urinary tract infections were collected.

Results: The rate of urinary tract infection in renal pelvic urine samples was 31.88%, in which gram – negative bacteria accounted for 76.19%. The most common isolated bacterial spp. was E.coli (46.15%), followed by Enterobacter cloacae, Proteus mirabilis, Staphylococcus aureus, Enterococcus faecalis and fungi. There was one case of sepsis, no septic shock or death recorded in our study.

Conclusions: Gram stain and renal pelvic urine culture are highly useful techniques to evaluate urinary tract infection when performing percutaneous nephrolithotomy. These techniques should be used for early detection and to minimize the rate of urinary tract infection complications such as sepsis and septic shock.
