肾盂输尿管连接部成形术主要解决患者肾盂与输尿管连接部分的血管异位。肾盂、输尿管连接部梗阻常常有管腔纤维性及炎性狭窄,外在异位血管、粘连等机械因素,又有高位连接、肌层发育不良所引起的由肾盏、肾盂起动的蠕动波传送失调。通过该手术可解除上述原因造成的尿液输送障碍,并可达到新型的管腔需要的正常管径;切除其余无张力的肾盂壁可使肾盂腔缩小,壁收缩有力;输尿管开口位于肾盂最低位,手术部输尿管与肾盂正位接合保持笔直,可防止盂管部手术区周围渗出液过多淤聚、纤维组织增生。腹腔镜辅助体外肾盂成形术结合了开放手术与腹腔镜手术的优点,使手术创伤减小,手术时间缩短,手术操作难度降低,术后恢复快,住院天数减少,效果满意,值得临床推广应用。
The ureteropelvic junctional angioplasty mainly solves the problem of vascular ectopia in the renal pelvis and ureter junction. Renal pelvis, ureter junction obstruction often have lumen fibrosis and inflammatory stenosis, external ectopic vessels, adhesions and other mechanical factors, there are high connections, dysplasia caused by the calyceal, renal pelvis peristalsis waves sent Disorder. Through the operation can relieve the above-mentioned causes of urinary transport disorders, and can achieve the normal requirements of the new diameter of the lumen; removal of the remaining tension-free renal pelvic wall can shrink the renal pelvis, wall contraction; ureteral openings located in the lowest renal pelvis , Surgical ureter and renal pelvis orthognathic joint to maintain straight, to prevent excessive oozing around the operative area of the oval tube deposition, fibrous tissue proliferation. Laparoscopy-assisted external pyeloplasty combined with the advantages of open surgery and laparoscopic surgery, surgical trauma reduction, shorter operative time, reduced surgical difficulty, rapid postoperative recovery, reduced hospitalization days, the effect is satisfactory, worthy of clinical application.
