RESUMO
OBJECTIVES: Surgical treatment of "Ren Mobilis" has historically been associated with poor results and fairly high morbidity. We have used a transperitoneal laparoscopic approach in order to minimize morbidity. The goal of this study was to evaluate the success rate and to discuss the possible pathogenic mechanism, which has implications for the surgical strategy. MATERIALS AND METHODS: Seven women with a right mobile kidney were examined by intravenous pyelogram and CT scans. Symptoms were judged to emanate from the mobile kidney. Transperitoneal laparoscopic nephropexy was performed. The surgical treatment consisted of fixing the kidney to the dorsal abdominal wall using tissue glue (Tisseel) after diathermy coagulation of the surfaces to induce fibrosis. The right colon was fixed with clips to the lateral abdominal wall, trapping the kidney in place. RESULTS: In 6 of the cases, there was an incomplete rotation of the ascending colon to the right side, allowing the kidney to move freely. In one case, the kidney moved into a retroperitoneal pocket of the mesocolon. The 6 cases with a lateral passage for the kidney were symptom-free at follow-up (30-80 months), but in the 7th case the patient's kidney quickly loosened and she underwent an open reoperation, after which she was symptom-free. CONCLUSION: Our series demonstrates that good results can be achieved with a transperitoneal laparoscopic approach, but also indicates that there is a common pathogenic mechanism with incomplete rotation of the ascending colon that can be corrected during surgery, which might contribute to the good results.
