Preliminary Study on the Results of the Analysis of Urinary Stones by Infrared Spectrophotometry in the Urology Department of the Pr BSS University Hospital in Kati

Introduction: Urinary lithiasis corresponds to the presence of one or more stones in the urinary tract. The etiology is multiple. The etiological investigation of urinary stones is based on morpho-constitutional analysis by infrared spectrophotometry. The objective of this work is to report the preliminary results of the analysis of urinary stones by infrared spectrophotometry. Materials and methods: This was a descriptive cross-sectional study with prospective collection carried out in the urology department of the Pr Sidy Sall University Hospital in Kati. It took place over a period from January 1, 2016 to December 31, 2018, or 36 months. Included in our study were all patients who were diagnosed with urinary lithiasis and who underwent spectrophotometric analysis after the intervention in the department. The supports of our study were: consultation records, surgical report records, hospitalization records, medical records, and the account of the analysis of stones by infrared spectrophotometry. The questionnaires were entered and analyzed on Word 2016, Excel 2016 and SPSS version 23.0 software after data verification. Results: we collected eighty-one (81) cases of urinary stones. Of the 81 cases, 15 patients were able to perform an infrared spectrophotometry analysis. In 66.67% of cases, there was at least 1 stone. In 60% of cases, the stone was of medium size. The stones were brownish in color in 73% of cases. Whewellite C1 and C2 stones were the most represented. In only one patient, the chemical composition of the stones was essentially made of whewellite. In a single patient, the chemical interpretation was essentially made of dietary hypercalciuria. The concentric and radial aspect of the calculus was essentially found in a single patient.
