ABSTRACT
Objective:To investigate the effect of timing of surgical treatment on renal function of children with solitary kidney and ureteropelvic junction obstruction (UPJO).Methods:The clinical data of patients with solitary kidney and UPJO admitted to Beijing Children′s Hospital, Capital Medical University and Shunyi Women′s and Children′s Hospital of Beijing Children′s Hospital from January 2006 to January 2018 were retrospectively analyzed.A total of 23 cases were enrolled, including 16 males and 7 females.The age of first visit ranged from 1 day to 15 years and 8 months (average: 2 years and 2 months). All the patients were conservatively treated for an average of 2 years and 9 months.SPSS 20.0 software was used for data analysis.Results:All patients received Anderson-Hynes pyeloplasty(A-H operation), and the age at operation ranged from 10 months to 16 years and 4 months, with an average of 4 years and 11 months.There were only 2 cases under 1 year old (10 months old and 11 months old, respectively). The double J stent was retained for 2 months after operation, and intravenous pyelography(IVP) was reexamined at 3 months after operation.The results showed that hydronephrosis either had no obvious change or was alleviated in different degrees.In 3 cases, IVP remained undetected for 40 minutes before operation.After operation, IVP was detected at 10-20 minutes.The follow-up period ranged from 1 year and 1 month to 10 years, with an average of 3 years and 9 months.Urinary ultrasound showed that the degree of pyeloplasty was less severe than that before operation.Conclusions:Close follow-up visits and conservative treatment of solitary kidney with UPJO are safe after 6 months.The first choice of operation is pyeloplasty.
ABSTRACT
Objective To investigate the timing and scheme of surgical treatment for the concomitant ureteropelvic junction obstruction(UPJO) and congenital abnormalities of the kidney.Methods The clinical data of 155 patients with concomitant UPJO and congenital abnormalities of the kidney from January 2006 to January 2016 was retrospectively analyzed.There were 107 males and 48 females,who aged 6 months to 16 years and 6 months.The average time was 5 years and 9 months old when they received operation.There were 8 cases less than 1 year old.There were 93 cases of UPJO on the left side,54 cases on the right side,and 8 cases on both sides.There were 33 cases with duplication of kidney,19 cases with solitary kidney,and 6 cases with renal dysplasia,6 cases with renal ectopia,12 cases with polycystic kidney disease,and 41 cases with dysplasia;2 cases with renal malrotation.There were 100 cases with symptoms such as fever,abdominal pain,vomiting.5 cases had received Anderson-Hynes pyeloplasty in other hospitals,2 cases received nephrectomy with symptoms did not relieve.4 cases were treated with nephrostomy in other hospital.Children with the repeated clinical symptoms,or renal function decreased significantly,or hydronephrosis progressive to the anteroposterior diameter of more than 30 mm received surgical treatment.Results There were 140 cases received Anderson-Hynes pyeloplasty,and 8 cases received nephrectomy with 5 cases were UPJO side and 3 cases were only abnormalities of the kidney without UPJO.All patients received IVP or ultrasonography postoperative 3-6 months,which showed hydronephrosis improved or no obvious change,and 4 cases were improved obviously.The IVP results showed that 5 patients with renal dysplasia together with UPJO had the renal function improved.There were 128 cases followed up for 12 to 106 months,with an average of 64.5 months.All patients had no clinical symptoms.83 cases were reexamined by IVP or ultrasonography,and hydronephrosis was getting better or no change.Conclusions The patients with concomitant UPJO and congenital abnormalities of the kidney don't need surgery in advance.The best choice for those patients is Anderson-Hynes pyeloplasty.The indication of nephrectomy should be considered carefully.
ABSTRACT
Posterior urethral valves(PUV) is the most common cause of lower tract obstruction in boys.With the understanding of the prognostic factors of PUV in depth,PUVs can have a profound effect on the function of bladder and upper urinary tract though valves are completely resected.The treatments of PUV include prenatal intervention,the antenatal vesicoamniotic shunt and fetal cystoscopy can be considered in selected patients with oligohydramnios.But the role of antenatal intervention is unclear.The gold standard for postnatal treatment of PUV is valve ablation.Vesicostomy is reserved primarily for the children with PUV whose urethra cannot accommodate an endoscope, as well as have severe urinary tract infections.Circumcision should be encouraged as a prophylactic measure for children with PUV who should have high rate of urinary tract infection.Vesicoureteral reflux is very common in PUV patients, and life-long monitoring of these patients is mandatory, as bladder dysfunction and valve bladder may be found during follow-up.These factors contribute toward the devolution of a bladder into dysfunction status are high voiding pressures and increased residual urine.Medication and clean intermittent catheterization are two main interventions, for the children who difficult to treat, an appendicovesicostomy utilizing the Mitrofanoff principle presents an useful option.Renal transplantation is an alternative for patients with PUV who progress to end-stage renal disease.Bladder dysfunction plays an important role in the development of PUV and urodynamic examination can be used to assess the function of the bladder to achieve timely and effective intervention.
ABSTRACT
Objective To understand the distribution of the blood donors with positive blood test results in Wuzhou .Methods The detection results of ALT ,HBsAg ,anti‐HCV ,anti‐HIV and anti‐TP of 108 879 cases of blood donors were retrospectively ana‐lyzed in 2010 -2012 .Results In the 108 879 cases of blood donors ,the total positive rate of 5 indicators was 6 .01% (6 548/108 879) .The positive rates of ALT ,HBsAg ,anti‐HCV ,anti‐HIV and anti‐TP were 4 .86% ,0 .57% ,0 .20% ,0 .07% and 0 .59% , respectively .The positive rates of ALT ,HBsAg and anti‐HCV were significantly different between males and females (P30 -40 age group had the highest anti‐HCV positive rate .Conclusion Enhancing the blood donation propaganda ,doing a good job in the blood before consulting ,and choosing low risk blood donors are important to guarantee of the blood quality and reduction of blood transfu‐sion transmitted diseases .
ABSTRACT
Blood sugar and potassium levels were mesured before and after intravenous injection of Etomidate to serve as an inducing agent in general anesthesea.The results showed that the blood potassinm in 31patients, the blood sugar in 29 patients were normal and had no statistical significance of difference.Hence the authors consider that Etomidate has neither influence on blood sugar nor on blood potassium.Etomidate is a safe, ideal intravenous anesthetic worthwhile to be recommended.
