Evaluation Of The Relationship Between Cardiovascular Risk Factors, Endoscopic Lesions Of The Renal Papilla And The Type Of Renal Lithiasis

Introduction and objetives: Study the relationship between the most frequent cardiovascular risk factors with the type of endoscopic injury of the renal papilla and the kind of renal lithiasis.Material and methods: We prospectively evaluated 38 patients undergoing retrograde intrarenal surgery (RIRS) by analyzing and classifying the type of injury observed in the renal papilla (Randall's plaque, intratubular calcification and papillary cleft). Later, we analyzed the type of lithiasis present (calcium oxalate monohydrate, uric acid and calcium oxalate dihydrate lithiasis with or without hydroxyapatite) and the cardiovascular risk factors present (HTA, Diabetes Mellitus, Obesity, Historiy of previous heart disease). A proportional comparison was performed using the x(2) test with significance value p < 0.05 for each group.Results: No relationship was found between the type of cardiovascular risk factor and the type of endoscopic papillary injury. Although, we find a tendency between the patients with obesity and the intratubular calcification. HTA and Diabetes Mellitus were related with uric acid stones (p = 0.025 and 0.005, respectively). Obesity was related with calcium oxalate dihydrate lithiasis (p = 0.023).Conclusions: There not seem to be a relationship between cardiovascular risk factors and the kind of renal papilla injury. In spite of, there is a tendency observed that correlated the patients with obesity with a high frequency of intratubular calcification. There seems to be a relationship between uric acid lithiasis in patients with diabetes or hypertension and another relationship between the calcium oxalate dihydrate lithiasis with or without hydroxyapatite and the patients with obesity.
