Abstract

Background One of the most prevalent long-term kidney disorders in high-blood-pressure patients is nephrolithiasis. This study involves collecting urine and renal stones from patients with urinary tract infection (UTI) to analyze how hospitalized patients with UTI contract community infections. The samples were collected at the Sulaimaniyah Surgical Teaching Hospital urology and extracorporeal shock wave lithotripsy (ESWL) staff. It is understood that UTIs contribute to the formation of kidney stones.

Methods Screened and cultured urine requires careful collection, transport, and interpretation. Urine samples were collected from the patients with UTI at the Sulaimaniyah teaching hospital for culturing. Urine cultures containing pyuria and bacteria indicate UTIs. Microorganisms were studied, inoculated on blood, MacConkey, and mannitol salt agar, and biochemically identified. A bacterial and microbiological examination of kidney stones was conducted at the Sulaymaniyah Surgical Teaching Hospital's ESWL and urology departments. Clean renal stone samples with ethanol for 1 minute, crush using sterile tongs, then culture in 37°C thioglycolate broth for 48 hours. Specimens inoculated on blood, MacConkey, and mannitol salt agars resulted in isolation of staphylococci, streptococci, and Staphylococcus spp.

Results In this study, 17 of 48 samples showed microbial growth. Each of Enterococcus and Micrococcus spp. comprised 12.5% of eight renal intact stone samples. Three of 14 renal intact stone samples showed microbial growth with 7 and 14% for Enterococcus and Escherichia coli, respectively. From eight urine samples before and after ESWL procedure, E. coli isolation incidents doubled from 12.5 to 25%, while Staphylococcus spp. remained the same at 12.5%. Out of 10 UTI urine samples, 20% Staphylococcus spp., E. coli, and 10% Pseudomonas spp. were isolated.

Conclusion This study related renal stones to E. coli, enterococci, Micrococcus luteus, and staphylococci. After ESWL, the urine samples revealed E. coli growth, whereas comparable urine samples before ESWL did not. Thus, urinary infections can cause kidney stones. Eighteen of 48 kidney stone samples tested positive for E. coli, 22 for staphylococci, 11 for enterococci, 5 for Pseudomonas, 5 for Proteus, and 5 for micrococci.
