Renal cyst is a common disease in humans and laparoscopic renal cyst decortication is the gold standard for treatment. However, specialized surgical skills are required for the treatment of renal parapelvic cysts. In this study, we describe an improved laparoscopic method for the treatment of renal parapelvic cysts involving the use of continuous infusion of methylene blue. Sixteen patients with renal parapelvic cyst were enrolled in this study. All patients underwent retrograde ureteral catheterization, with continuous perfusion of the renal pelvis using a solution of 0.2% methylene blue and saline, during laparoscopic decortication of the parapelvic cyst. In one patient, the cyst communicated with the renal collection system which was injured, but this was immediately repaired intraoperatively. All operations were successful, and none was converted to open surgery. There were no occurrences of persistent urinary fistula, bleeding, or other complications postoperatively. All patients were followed-up for 3-24 months, and results of postoperative imaging investigations revealed that all of our patients experienced either complete recovery or a greater than 50% decrease in size of the cysts. Our study demonstrates that methylene blue-assisted laparoscopic treatment is a safe, effective and practical method for the treatment of renal parapelvic cysts.
肾囊肿是人类的一种常见疾病，腹腔镜肾囊肿去顶术是治疗该病的金标准。然而，治疗肾盂旁囊肿需要专业的手术技能。在这项研究中，我们描述了一种改良的腹腔镜治疗肾盂旁囊肿的方法，该方法涉及使用亚甲蓝持续输注。本研究纳入了 16 例肾盂旁囊肿患者。所有患者均在腹腔镜下进行肾盂旁囊肿去顶术时接受逆行输尿管置管术，用 0.2%亚甲蓝和生理盐水溶液持续灌注肾盂。在 1 例患者中，囊肿与肾盂集合系统相通并被损伤，但术中立即进行了修复。所有手术均成功完成，无一例转为开放性手术。术后无持续性尿瘘、出血或其他并发症发生。所有患者均随访 3-24 个月，术后影像学检查结果显示，所有患者的囊肿均完全消退或缩小超过 50%。本研究表明，亚甲蓝辅助腹腔镜治疗是一种安全、有效、实用的治疗肾盂旁囊肿的方法。
