DJ (Double J) stent migration is a significant clinical issue that can affect patient outcomes and necessitate additional interventions. This study aims to identify the factors influencing DJ upward migration, focusing on patient demographics, anatomical characteristics, and procedural parameters.

A retrospective analysis was conducted on patient data, including age, gender, BMI, ureteral length, DJ stent diameter, stone encrustation, hydronephrosis status, and migration laterality. Statistical models were applied to determine associations between these variables and the occurrence of DJ stent migration.

A total of 82 patients were included in the analysis, with 18 patients categorized into the upward migration group and 64 patients in the control group. Age and preoperative hydronephrosis severity were significantly different between the two groups. Older age (p=0.038) and higher degrees of preoperative hydronephrosis (p=0.003) were positively correlated with DJ stent migration. Additionally, poor DJ stent coiling (p < 0.001) was associated with an increased risk of subsequent migration.

The findings indicate that specific anatomical and demographic factors contribute to DJ stent migration. Optimizing stent selection based on patient-specific parameters may help mitigate the risk of migration. Further research with larger sample sizes and prospective validation is recommended.
