Abstract：
BACKGROUND: This study aimed to assess the feasibility, safety, and efficacy of an endoscopic parapelvic renal cyst (PRC) incision using flexible ureterorenoscopy (fURS).
METHODS: We retrospectively reviewed data concerning 16 patients in whom PRC incisions had been performed using fURS between January 2016 and January 2022. Two patients were excluded from the study owing to a lack of follow-up information. The cysts of all the patients were evaluated preoperatively by computed tomography. The patients\' age, gender, cyst size, presenting symptoms, postoperative complications, and pre- and post-treatment visual analogue scale (VAS) scores were evaluated. Surgical success was defined as a reduction of more than half of the cyst size in the sixth postoperative month.
RESULTS: A total of 14 patients were included in this study. The patients\' mean age was 52.6 ± 8.8 years, and the mean cyst size was 69.1 ± 15.5 mm. Twelve (85.7%) patients presented with flank pain. Clavien-Dindo grade 1 complications were observed in two patients (14.3%), and grade 2 complications were observed in one (7.1%). The median VAS scores were significantly lower after treatment than before in patients who presented with flank pain (2 (1-2.8) vs 8 (7-8), respectively; p = 0.002). Surgical success rate was detected in 11 patients (78.6%) six months after the treatment.
CONCLUSIONS: Endoscopic incision of the PRC is a feasible treatment modality with high success rates and low complication rates. However, multicentre studies with larger populations and longer follow-ups are needed to evaluate the lasting effects.

摘要：
背景：本研究旨在评估可行性，安全,和使用输尿管软镜（fURS）的内镜下肾盂旁肾囊肿（PRC）切口的疗效。
方法：我们回顾性分析了2016年1月至2022年1月期间使用fURS行PRC切口的16例患者的数据。由于缺乏随访信息，两名患者被排除在研究之外。所有患者的囊肿均在术前通过计算机断层扫描进行评估。病人的年龄，性别,囊肿大小,出现症状，术后并发症,评价治疗前后视觉模拟评分(VAS)评分。手术成功定义为在术后第六个月囊肿大小减少一半以上。
结果：本研究共纳入14例患者。患者平均年龄为52.6±8.8岁，平均囊肿大小为69.1±15.5mm。12例（85.7％）患者出现侧腹疼痛。在两名患者中观察到Clavien-Dindo1级并发症（14.3％），1例(7.1%)出现2级并发症.治疗后出现侧腹疼痛的患者的中位VAS评分明显低于治疗前（2（1-2.8）vs8（7-8），分别为；p=0.002)。治疗6个月后11例(78.6%)患者手术成功率。
结论：内镜下PRC切开是一种可行的治疗方式，成功率高，并发症发生率低。然而,需要更多人群和更长时间随访的多中心研究来评估持久效果。
