Abstract: 【Abstract】〓Objective〓To investigate the renal pelvic pressure trends after pyeloplasty for children with congenital hydronephrosis. Methods〓Thirty patients who underwent Anderson–Hynes pyeloplasty for ureteropelvic junction obstruction were included in a retrospective analysis. Nephrostomy tubes were placed when the operations were performed. After surgeries, renal pelvic pressure, bladder pressure and urine volume of the hydronephrotic kidneys were measured every day,and lasted for 14 days. Results〓Renal pelvic pressure decreased to the same level of bladder pressure 1 day after operation, while increases temporary 1 week later, and then decreased to a steady level. Urine volume of hydronephrotic kidneys also increased temporary 1 week after operation. Conclusion〓Anastomosis functional obstruction exited within one week after operation.

摘要: 【摘要】〓目的〓探讨先天性肾积水小儿行离断式肾盂输尿管成形术后肾盂内压力的恢复规律。方法〓回顾性分析30例单侧肾盂输尿管连接部狭窄行离断式肾盂输尿管成形术的患儿。术中放置肾造瘘管。手术后14天内,每天测量肾盂内压力、膀胱内压力、患侧尿量。结果〓术后第一天,患侧肾盂内压力即降低至和膀胱内压力无明显差异。术后7天左右,肾盂内压力短暂升高,之后再次降低并保持稳定。患肾尿量于术后7天左右短暂性增多。结论〓术后7天左右,吻合口存在“功能性”梗阻。肾造瘘管或者输尿管支架管至少应该放置1周。
