To present our initial experience of robotic ureteroplasty with lower-lip mucosal graft (LLMG) for treating ureteral stenosis longer than 2 cm and evaluate its feasibility and efficacy.
A total of thirteen patients with ureteral stenosis who underwent robotic ureteroplasty with LLMG were retrospectively analyzed. After identification and dissection of the ureteral stenosis segment, the segment was incised longitudinally. Then, the LLMG was harvested according to the characteristics of stenosis and sutured with the ureter in onlay fashion. All procedures were completed successfully.
The median stenosis length was 3.5 cm (ranged: 3.0-4.5 cm). The mean length and width of the LLMG were 3.81 ± 0.60 cm and 1.27 ± 0.26 cm, respectively. The mean operative time and anastomosis time were 212.31 ± 23.06 min and 36.54 ± 6.58 min, respectively. The double-J stent was removed at 8 weeks postoperatively in all patients. Three patients (23.1%) suffered postoperative complications during the follow-up period (range, 6-18 months), including fever, urinary tract infection and stenosis recurrence. The success rate was 92.3% (12/13).
Robotic ureteroplasty with LLMG is a safe and feasible technique for treating ureteral stenosis.
介绍我们使用下唇黏膜移植物（LLMG）进行机器人输尿管成形术治疗长度超过2 cm的输尿管狭窄的初步经验，并评估其可行性和疗效。
回顾性分析13例行LLMG机器人输尿管成形术的输尿管狭窄患者。识别并解剖输尿管狭窄段后，纵向切开该段。然后，根据狭窄的特点采集LLMG，并以覆盖法与输尿管缝合。所有手术均成功完成。
狭窄长度中位数为3.5 cm（范围：3.0 - 4.5 cm）。LLMG的平均长度和宽度分别为3.81±0.60 cm和1.27±0.26 cm。平均手术时间和吻合时间分别为212.31±23.06分钟和36.54±6.58分钟。所有患者均在术后8周取出双J支架。3例患者（23.1%）在随访期间（6 - 18个月）出现术后并发症，包括发热、尿路感染和狭窄复发。成功率为92.3%（12/13）。
LLMG机器人输尿管成形术是治疗输尿管狭窄的一种安全可行的技术。
