Objective:
To evaluate the impact of coiling of the proximal end of the ureteral stent on stent-related symptoms (SRS) in in subgroup of patients undergoing preoperative ureteral stenting preceding flexible retrograde intrarenal surgery (RIRS).
Materials And Methods:
We performed a prospective comparative study including patients undergoing stent placement 7-10 days prior to RIRS. Patients were divided into 2 groups; in Group 1 coiling of proximal end of the DJ was present, while in Group 2 coiling was absent. Bladder pain, flank pain, hematuria, urgency, frequency, nocturia, and urge incontinence were evaluated on the day of surgery using Visual Analog Score (VAS).
Results:
In total, 81 patients, 45 males (55.6%) and 36 (44.4%) females were included. Patients in Group 2 had statistically significant severe representation of flank (43.2% vs. 22.7%, p-value = 0.049) and bladder pain compared to Group 1 (48.4% vs. 25.0%, p-value = 0.027). Additionally, they required analgesic medications more frequently (64.9% vs. 34.1%, p-value = 0.006), and experienced significantly more pronounced frequency (p-value = 0.012) and urgency (2.7 vs. 2.1, p-value = 0.033) compared to Group 1. Patients in group 1 recovered from their symptoms more frequently (52.3% vs. 29.7%, p-value = 0.041), occurring on day 4 and 5 following ureteral stenting.
Conclusion:
Coiling of the proximal end of the DJ stent impacts stent-related symptoms significantly. Better outcomes of post-procedural frequency, urgency, bladder and flank pain were observed in patients in whom coiling was achieved. Moreover, those patients reported faster recovery from SRSs.
