- Abstract:
- Objective To explore the risk factors of failed insertion of double J stent into bladder during operation of ureteropelvic junction obstruction (UPJO) and provide rationales for selecting suitable treatments.Methods Retrospective analysis was performed for 96 cases of dismembered pyeloplasty from June 2012 to September 2017.According to the placing success of double J tube,it was divided into successful group (n=78) and failure group (n=22).There were 78 boys and 18 girls with an age range of 3 months to 12 years.The sideness of hydronephrosis was left (n=60),right (n=23) and bilateral (n=13).Results The proportion of ureteral stenosis was 8/22(36.4%) and 0/74(0%) in failed and successful groups respectively and the difference was statistically significant (χ2=29.350,P<0.001).The failed group and successful combination of contralateral hydronephrosis were 7/22(31.8%) and 7/74(9.6%) respectively (P<0.05) and the difference was statistically significant (χ2=6.648,P=0.010).No statistically significant inter-group difference existed in history of urinary tract infection,history of ureteral operation,history of renal dysplasia,or abdominal pain(P>0.05).Conclusion Stenosis of ureteral bladder junction should be considered in case of a blockage of double J tube.Concurrent contralateral hydronephrosis hints at a higher probability of failed placement of double J stent.Traditional nephrostomy is preferred for treatment.
