Introduction:
Forgotten double JJ stents is the most common reason for postoperative complaints in urology. Thorough preoperative mapping of stent's calcification is mandatory to offer tailored management. The aim of our study was to assess the correlation between the Kidney Bladder Ureter (KUB) score and the complexity of surgical management.
Materials And Methods:
We retrospectively gathered data from patients who had a forgotten JJ stent with failed removal under local anesthesia. We have looked for relationship between the KUB score and the complexity of management. Correlated factors with the KUB score have been looked for too.
Results:
Thirty-four patients were evaluated during the study. Forty renal units were managed. The average duration of JJ catheter implantation was 951.77 (185-3522) days. A total KUB score≥6 was a predictive factor for the need for complex management (OR=11.39; IC95%: 2.35-35.18). Cognitive disorders (P=0.001), ASA score (P=0.016), social isolation (P=0.003), urinary lithiasis (P=0.048), and the emergency context of JJ stent placement (P=0.001) were significantly associated with a high total KUB score (≥6). In contrast, French nationality (P=0.09), male gender (P=0.7), duration of JJ stent placement (P=0.6), and type of JJ stent (P=0.4) were not significantly associated with the total KUB score.
Conclusion:
A high KUB score is a predictive factor of complex management of forgotten JJ stents. Preventing the forgetting of JJ stents is essential and would now be easier by digital means. A French application for tracking JJ stents could improve the national traceability of these stents.
