Abstract:
ObjectiveTo evaluate the application of multi-slice CT (MSCT) perfusion scan technique in predicting renal function recovery after unilateral hydronephrosis treatment.MethodsThirtyeight patients with unilateral obstructive hydronephrosis not shown on intravenous urography (IVU) and a normal contralateral kidney were recruited for this study.Patients were divided into detected (D) and undetected (UD) groups depending on whether the IVU detected urinary tract obstruction.All patients underwent plain abdominal X-ray,gray-scale ultrasonography,excretory urography and MSCT perfusion scan before and after the treatment.Patients were followed-up at six months or more after the treatment for a mean duration of 12.5 months (range from 6 to 22 ).ResultsOf the 38 cases,22 cases were in group D,16 cases were in group UD.On MSCT,renal cortex blood flow (BF) and blood volume ( BV ) value after treatment in group D were 561.1 ± 165.4 ml/( 100 g · min) and 35.9 ± 11.3 ml/100 g compared with before treatment rates of 361.6 ±109.7 ml/(100g· min) and24.1 ±10.2 ml/100g,t=-3.38,-2.34,P＜0.01,0.05.In the UD group,the differences of these parameters were after treatment 38.7 ± 15.4 ml/(100 g · min),10.306 ± 4.925 ml/100 g and before treatment 39.1 ± 22.5 ml/( 100 g · min) and 8.7 ± 4.4 ml/100 g,P ＞ 0.05.In the aspects of BF and BV,there were statistically significant differences between group D and group U D both before and after the treatment,t=9.09,4.15,P ＜ 0.01.ConclusionsM SCT perfusion can provide a valuable prediction technique of the renal function recovery in patients with unilateral obstructive hydronephrosis.Improvement of renal function can be expected after relief of obstructive hydronephrosis if the patients have a BF 361.6 ml/( 100 g · min) and BV 24.1 ml/100 g or greater measured by MSCT perfusion.
