【摘要】 目的　观察重度肾积水患儿术后肾脏功能的恢复情况及影响因素。方法　利用ECT检查 ,测定 5 0例患儿术后患肾功能 ,2 0例患儿手术前后患肾功能 ,并分析影响患肾功能恢复的因素。结果　 5 0例患儿术后患肾功能平均为 (4 0 .6 2± 10 .0 9) % ,其中 32 %的患儿术后患肾功能接近正常 ,分肾功能达 45 %以上。 2 0例患儿手术前后患肾功能分别为 (2 0 .45± 9.5 0 ) %和 (37.10± 9.16 ) % ,患肾功能提高 (16 .73± 11.5 1) % (P =0 .0 0 0 5 )。术中测量的患肾实质厚度和术后患肾功能的恢复呈负相关 (r =- 0 .79,P =0 .0 0 4) ;随访时间和术后患肾功能的恢复呈正相关 (r =0 .76 ,P =0 .0 14) ;手术时年龄和患肾功能恢复无显著相关性 (r =- 0 .5 7,P =0 .12 )。肾外型肾积水术后患肾功能恢复明显高于肾内型肾积水 (P =0 .0 44 )。结论　重度肾积水患儿术后患肾功能可获得很好的恢复 ,部分患儿患肾功能恢复接近正常 ,应保留患肾。肾实质薄者 ,随访时间长者及肾外型肾积水患肾功能恢复明显。更多还原

【Abstract】 Objective To observe the convalescence and factors influencing on the renal function in children with congenital hydronephrosis after operation. Methods The postoperative renal function of 50 cases and preoperative and postoperative renal function of 20 patients were determined by ECT. Factors that influenced on the convalescence were analyzed. Results The average postoperative renal function of 50 cases was 40.62 ± 10.09 %. The renal function of some patients (32% ) was near normal. The differentiated renal function reached up to 45%. The average preoperative and postoperative renal function of 20 cases was 20.45 ± 9.50 % and 37.10 ± 9.16 % respectively. The parenchyma thickness was negatively correlated with postoperative renal function ( r= 0.79 ,P = 0.004 ) . The follow-up period was positively correlated with postoperative renal function ( r= -0.57 , P = 0.12 ). The recovery of renal function in hydronephrosis with extrarenal pelvis was obvious than that with intrarenal pelvis ( P = 0.044 ).Conclusions The postoperative renal function in children with hydronephrosis can recover to normal. The recovery is obvious in cases with thinner renal parenchyma, longer follow-up and extrarenal pelvis.更多还原
