ABSTRACT
Objective@#To investigate the corrective effect of modified Brisson technique to treat concealed penis in children.@*Methods@#From July 2015 to July 2017, 32 patients(3-10 years old, mean 7.2 years old )with concealed penis were treated with the modified Brisson technique in the Children′s Hospital of Zhengzhou University. All the children with concealed penis were treated by the modified Brisson technique, complications, postoperative results and followed-ups were retrospectively analyzed.@*Results@#32 cases of concealed penile children had pain on the postoperative day, 2 cases required patient controlled analgesia device. No infection and dehiscence were noticed after discharge. All the children were followed up for 6 months to 1 year, and the results were satisfactory. Review showed that the penile body was similar to the appearance after circumcision, with obvious extension exposure, normal exposure of penile scrotal Angle and penile pubic Angle, and no obvious retraction. The internal plate of the prepuce in 5 cases was slightly edema, and edema dissolved within 2 months.@*Conclusions@#Modified Brisson is a better method to treat concealed penis in children, which can correct the pathological structure and retain the integrity of penile skin to the greatest extent.
ABSTRACT
Objective To explore the determination of urinary angiotensinogen (uAGT) in the urine of children with obstructive hydronephrosis and its relationship with impaired renal function, to provide a new and rapid reference index for the preoperative evaluation and postoperative follow-up of the children with hydronephrosis.Methods The data were collected from 48 children who were diagnosed as unilateral congenital renal pelvis and ureter obstruction in the outpatient or inpatient Department of Pediatric Surgery of the First Affiliated Hospital of Zhengzhou University,which were divided into operation group and non-operation group.There were 28 children in operation group(who were all severe hydronephrosis) ,who were all operated with dismembered pyeloplasty.There were 20 children in the non-operation group (who were all mild and moderate hydronephrosis).They temporarily had no surgery signs and hydronephrosis did not become increasingly serious for assuring the regular outpatient follow-up after being diagnosed as hydronephrosis;there were 20 children in the control group, 10 of which were male, and 10 female.The males were hospitalized children with hydrocele and the females were with inguinal hernia.Gender composition among the 3 groups, and the average age difference was not statistically significant.The clean urina of children in 3 groups was collected,3 times for operation group, once before operation and once in 6 weeks and once in 12 weeks after operation;3 times for non-operation group and control group with interval of 6 weeks in outpatient clinic.The children in operation group and non-operation group were all scanned for glomerular filtration rate (GFR) of diseased renal with radionuclide;enzyme-linked immunosorbent assay (ELISA) was adopted to determine the content of uAGT in the urine of the 3 groups of children, and automatic biochemical analyzer was used to measure the amount of urine creatinine (uCr).Results Before operation, in 6 weeks and 12 weeks after operation, uAGT / uCr average water of non-operation group and control group was significantly lower than the operation group, all the differences were statistically significant (F =34.360,14.683,5.035, all P ＜ 0.05).Preoperative and postoperative uAGT / uCr and GFR of diseased renal were of negative correlation(r =-0.647,-0.786, all P ＜ 0.05).In operation group, the preoperative and postoperative GFR average of diseased renal was 37.18 ± 7.31 and 45.27 ± 8.18.The difference of GFR changes was statistically significant before and after treatment (t =-3.971, P =0.000).Conclusions uAGT/uCr increased evidently in congenital renal pelvis and ureter obstruction patients who needed operation, so increase of uAGT might be the indicator of impaired renal function caused by obstructive hydronephrosis of children.
