    Abstract:
    OBJECTIVE: In Morocco, few works on morpho-constitutional analysis of urinary calculi have been published, especially for patients in the region of Fez. This work aims to make a retrospective epidemiological study on the nature of urinary calculi with patients from the region of Fez and control the urine of the same patients after a period of three months to report on the risk of recurrence. METHOD AND PATIENTS: Urinary stones were collected mostly in the nephrology service and urology service at the Hassan II Hospital in Fez. These calculations after being dried for 24 hours at room temperature underwent a morphological analysis, followed by infrared spectroscopic analysis Fourier transform. After a period of about three months, morning urine of the same patients was analyzed by crystalluria to control the presence of crystals that reflect a risk of recurrence. RESULTS: In our series of 123 samples, the age of patients ranges from 2-79 years. The prevalence was higher for men with a sex ratio of 1.3. The results of the analysis calculations showed that 61% were formed of calcium oxalate and 15% of uric acid and 25% of stones were carbapatite, struvite, cystine… The study by crystalluria urine revealed the presence of the crystals in 69% of patients' nephrolithiasis. CONCLUSION: The results of our study are conformed to the series of results in other regions of Morocco regarding the predominance of calcium oxalate stones. The presence of crystals in the urine of 69% of patients may indicate other recurrences. LEVEL OF EVIDENCE: 4.
