Minimally invasive treatment of calcified double J catheter

Introduction: The calcification of the double J catheter can be found in 13% of those placed and increases proportionally to the time it remains in contact with urine. The researchers agree that the calcified double J catheter is a complex complication to resolve. A bibliographic review was carried out, from 2011 to 2021. The resources of the SciELO, EBSCO, Elsevier and PubMed databases were used in relation to the descriptors lithiasis, catheters, minimally invasive surgical procedures and intraoperative and postoperative complications. Objective: To describe the role of minimally invasive surgery for the treatment of calcified double J catheter. Development: The risk factors related to calcified double J are clinical-therapeutic and sociodemographic, such as urinary tract infection, history of lithiasis, pregnancy, chronic kidney disease, metabolic or congenital anomalies. Those made of polyurethane have higher rates of calcification. Extracorporeal shock wave lithotripsy can be used in up to 70.7% of patients. Multimodal methods such as ureteroscopy prior to transurethral cystolithotripsy have been applied between 6-17.9%, percutaneous nephrolithotomy and ureteroscopy prior cystolithotripsy or not in 7.7%-20%. The most frequent complications are reported during the postoperative period (20%): fever, pain, vomiting, hematuria, pyelonephritis, sepsis, urinoma, spontaneous migration of the newly placed catheter, and acute kidney injury, among others. Conclusions: Minimally invasive surgery is currently the cornerstone of treatment for patients with calcified double-J catheters.
