Lithiases urinaires et pathologies digestives : une revue de la littérature
Résumé
Purpose - The aim of the study was to explain the relationship between urinary stones and bowel disease. Methods - A systematic review was performed on Medline, Embase and Cochrane using following keywords: urinary stones; urolithiasis; bowel; enteric and digestive. The literature selection was based on evidence and practical considerations. Results - Fifty-three articles were selected. Three types of urolthiasis are mainly involved in digestive pathologies: calcium oxalate stones, uric acid and ammonium acid urate stones. Bowel pathologies responsible for stone disease are divided into small bowel diseases, colonic lesions and lack of an oxalate degrading bacteria (Oxalobacter formigenes) in the intestinal flora. Resulting in a decreased urine output, pH, hyperoxaluria, hypocitraturia or a hypomagnesurie. Blood and urinary explorations are the basis of diagnostic management. Conclusion - Bowel diseases can be responsible for urolthiasis. Understanding of the mechanisms, and metabolic evaluations can prevent recurrences. Increase fluid intake associated with specific supplementation and diet are the key of the treatment.
