Abstract :
Aim: The aim of the study is compare the reliability and efficacy of full urine tests and urine cultures in kidney and/or ureter stone patients. Materials and Methods: Between January 2011- January 2013, 471 patients who were admitted to our clinic with symptomatic ureter and/or kidney stones were evaluated (Group 1). These patients had a full urine test, urine microscopy and urine culture. The control group (Group 2),consisted the patients who admitted with symptomatic urinary tract infection (UTI) in the same period. The patients who did not have all three diagnostic tests were excluded. Results were evaluated with chi-square and student’s t test by SPSS v.19.0. p 0.05 is considered as statistically significant. Results: Sixty-eight (11.3%) patients had a positive urine culture. E.coli (77.9%) is the mostly isolated bacteria. Twenty-nine (9.9%) of stone patients and 39 (%13) of non-stone patients had a positive urine culture. For Group 1, negative predictive values of nitrite, leucocyte, erytrocyte and bacteria seen in microscopy were 93%, 96%, 96% and 90%, respectively. For Group 2, negative predictive values of nitrite, leucocyte, erytrocyte and bacteria seen in microscopy are 88.8%, 93.3%, 93.2% and 87.1%, respectively. Conclusion: Full urine tests (pyuria, hematuria, bacteriuria, nitrite tests), are not enough to diagnose urinary tract infection, especially for complicated UTI. These tests should be correlated with urine cultures. Full urine tests can also be used in uinary stone patients safely. However, urinary stone patients with UTI can also be categorized as complicated UTI, and all shoud be evaluated by urine culture.
