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).
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).
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.
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.
评估在接受术前输尿管支架置入术的患者亚组中，输尿管支架近端盘绕对支架相关症状（SRS）的影响，这些患者随后接受软性逆行肾内手术（RIRS）。
我们进行了一项前瞻性对照研究，纳入在RIRS术前7 - 10天接受支架置入的患者。患者分为两组；第1组DJ支架近端存在盘绕，而第2组不存在盘绕。在手术当天使用视觉模拟评分法（VAS）评估膀胱疼痛、胁腹疼痛、血尿、尿急、尿频、夜尿症和急迫性尿失禁。
共纳入81例患者，其中男性45例（55.6%），女性36例（44.4%）。与第1组相比，第2组患者的胁腹疼痛（43.2%对22.7%，p值 = 0.049）和膀胱疼痛（4
