The effect of excess length of double J stent on stent related symptoms
Keywords:Double J stent, Stent-related symptoms
Objective: To evaluate the relation between the excess length of double J stent on urinary symptoms and pain in patients who indwelling double J stent.
Method: A total of 41 patients, who had opted for management with insertion of a 6 F double J ureteral stent after stone management and undergone intravenous pyelography or retrograde pyelography before procedure, were prospectively observed. Tolerance to the indwelling double J stent was assessed using a urinary symptom questionnaire and pain score at 2 weeks after placement.
Results: The urinary symptoms varied from 6 to 27 with mean of 15.1 (SD=4.4) and median of 16. Plot of excess length of double J stent against urinary symptoms revealed a positive correlation with Spearman r of 0.506 (p=0.001). The mean excess length of double J stent which causing significant symptom score was 4.3 cm. The excess length of double J stent against pain score showed a positive correlation with Spearman r of 0.353 (p=0.023).
Conclusions: The excess length of double J stent, measured from imaging ureteral length, was positive correlation to urinary symptoms. The urinary symptoms were significant when excess length of double J stent more than 4.3 cm. The ureteral length from imaging may be helpful for stent selection to reduce stent related symptoms
