Urological emergency in neonates with congenital hydronephrosis

OBJECTIVE: It is well described that unilateral pelviureteric junction obstruction (PUJO) is a benign condition, because the dilatation resolves spontaneously and the function does not decrease in most of the kidneys. However, there is exceptional PUJO that requires emergent treatment in neonatal periods. The aim of this article is to report the urological emergency and management in neonates with PUJO. MATERIALS AND METHODS: Nine children (seven boys and two girls) with PUJO who underwent neonatal emergent treatment during the last 13 years were reviewed. Renal function was evaluated according to decay curve of serum creatinine (SCr) levels corresponding to gestational age (GA) at delivery. Physical examination, ultrasonographic monitoring, and chest and abdominal plain radiographs were repeated in each neonate. RESULTS: Eight patients were detected prenatally. In five patients, multicystic dysplastic kidney (MCDK) was demonstrated on the contralateral side. Three patients underwent percutaneous puncture of fetal hydronephrosis. Decrease of amniotic fluid was evident in three fetuses. Indications for emergent treatment included mass effect from hydronephrosis in three patients, renal dysfunction in five, and severe urinary tract infection in one. During neonatal periods, a percutaneous nephrostomy tube was placed in seven, and open nephrostomy in one with anorectal malformation. Repeated punctures of the dilated renal pelvis were done in one patient. Renal function after pyeloplasty was stable in eight patients, while it was moderately decreased in one who was associated with oligohydramnios in utero. CONCLUSION: Indications for emergent treatment in neonates with PUJO included mass effect from giant hydronephrosis, renal dysfunction and severe urinary tract infection. At birth, respiratory and circulatory conditions must first be stabilized. In neonates with hydronephrosis of the solitary kidney or severe bilateral PUJO, serial SCr should be monitored to evaluate renal function. Decrease of amniotic fluid suggested renal functional compromise that would not recover after urological management.     

The Experiment of Gene Therapy for Gallbladder Carcinoma Cell in Vitro with Herpes Simplex Virus Thymidine Kinase/Ganciclovir

Objective To evaluate preliminarily the effect of HSV - tk/GCV system on gallhladder carcinoma cells in vitro.Methods Recombinant retroviral vector PLtkSN containing tk suicide gene was transfacted into gallbladder carcinoma cells, mediated by LipofectAMINETM 2000 liposome, and the growth - inhibiting rotes of GBC, SD/tk cells in the different GCV concentrations were measured by MTr methods; GBC - SD cells were mixed in the different proportions, and death rotes of the mixed cells treated with GCV were detected to verify by stander effect. Resuts GCV could lead GBC - SD/tk cells to significant death, and there was striking difference compared with the control cells （p〈0.01）. When the concentration of GCV was 1,10, 50,100,500ug/ml, the killing rate of GBC - SD/tk cells was respecfively 6.8%, 2.5.2%, 54.5%, 66.3%, 89.3%, indicating dose - dependent phenomenon; With GBC - SD/tk cells in the proportion of 0, 10%, 20% ,50%, 70%, 100%, the killing rate of the mixed cells treated with GCV was 0, 19.7%, 40.3%, 77.7%, 88.0%, 93.5%, respectively. It was apparent that bystander effect was observed in the experiment. Condusion HSV - tk/GCV system could be a potential tool for the treatment of carcinoma.
