Crystalluria is characterized by the presence of crystals in urine sediment. Urinary crystals are now recognized as an important biomarker in urinalysis for identifying various underlying health conditions. Urinary tract infection (UTI) is a collective term for infections of any part of the urinary tract, i.e. the kidneys, ureters, bladder and urethra. UTI are the most common bacterial infection affecting 150 million people each year worldwide. Urinary tract infection (UTI) is a common complication that arises during pregnancy. Around the 6th week of pregnancy, the ureters start to widen due to the physiological changes of pregnancy, reaching its peak at 22-26 weeks and lasting until delivery. E. coli is the most commonly grown pathogen seen in case of UTI. Approximately 85% to 90% of UTIs are caused by Escherichia coli. Other than Escherichia coli, Klebsiella pneumonia, Proteus mirabilis, staphylococcus aureus, Pseudomonas aeruginosa, and Enterobacter spp. were observed causing UTI. The study design used for this research was Experimental. This study was conducted at Railway General Hospital from January 2024 to June 2024. A total of one hundred and fourty four patient specimens were analyzed for the entire duration of research. Purposive sampling technique was applied to select the research participants. One hundred and fourty four early morning mid-stream urine specimens were taken for UTI analysis. The majority of the samples (69.44%) did not contain any detectable crystals. Among the samples with crystalluria, calcium oxalate was the most prevalent type, present in 27.08% of the cases. Amorphous urates and amorphous phosphate crystals were found in 1.39% and 2.08% of the samples, respectively. Amorphous urate crystals were least prevalent. Escherichia coli and Staphylococcus aureus are the main uropathogens causing UTI in pregnant woman that is 38% caused by Escherichia coli and 24% caused by Staphylococcus aureus respectively. Followed by Klebsiella pneumoniae and Enterococcus faecalis i.e. 16 % and 9% respectively. Pseudomonas aeruginosa and Acinetobacter baumannii are the least common cause of UTI among pregnant women that is 4.2% and 2.8% respectively. The correlation coefficient of age is -0.015 showing negative correlation between age and crystal as shown in the table. The p value is 0.144 which shows that there is insignificant relationship between age and crystals. The correlation coefficient of specific gravity is -.216** showing negative correlation whereas the p-value is 0.009 showing that is significant between crystals and specific gravity. The correlation coefficient of crystal and pH is -.091 which shows negative correlation between crystals and pH. The p-value is 0.47 showing insignificant association between crystals and pH. .Crystalluria occurs in UTI related pregnancies so should be properly diagnosed and treated.
