该文报道了1989年3月以来，对30例全身条件较好的闭合性或医源性肾损伤导致的肾出血病例，早期采用膀胱镜窥视下输尿管逆行插管，行患例肾盂内止血药液等持续冲洗治疗，其中25例患者肾出血得到控制，明显优于单纯静脉给药，最大限度地避免了开放性肾探查手术可能给患者带来的较大损伤。提出在明确诊断和病人全身条件允许的情况下，早期运用腔内泌尿外科技术施行肾盂止血药法灌洗，既可以直接作用于受损伤的肾小血管，促使其收缩和修复，又可以清除已产生的血凝块等，有利于损伤肾脏本身的收缩达到止血目的。对肾损伤的内镜下治疗进行了探讨。 This article reports the cases of renal hemorrhage caused by closed or iatrogenic renal injury with good general condition in 30 cases since March 1989. Early retrospective ureteric retrograde intubation with cystoscopy was performed. The patients underwent renal pelvis hemostatic Fluid and other continuous flushing treatment, of which 25 patients with renal bleeding control was significantly better than simple intravenous administration, to maximize the open kidney exploration to avoid possible greater damage to patients. Proposed in a clear diagnosis and the patient’s systemic conditions permit the early use of endoscopic urinary catheterization hemostatic pharmacological lavage, either directly on the injured renal blood vessels, to promote its contraction and repair, but also can be cleared Resulting in blood clots and other conducive to damage the kidney itself to achieve the purpose of bleeding to stop bleeding. Endoscopic treatment of renal injury were explored.
