ABSTRACT
Objective To explore clinical application of neotype controllability artificial nephrohydrosis in percutaneous nephrolithoto-my. Methods 400 patients with renal lithiasis or superior segment ureter lithiasis in our hospital were divided into group A and group B. 200 cases of group A received neotype controllability artifiicial nephrohydrosis;200 cases of group B received conventional artificial nephro-hydrosis. The puncture duration, amount of bleeding and times of puncture of the two groups were compared. Results 195 cases in Group A were developed renal tract for PCNL effectively,157 cases were developed renal tract for PCNL effectively in Group B. The puncture duration, amount of bleeding and times of puncture of group A and group B were respectively (1. 8 ± 0. 7) vs. (2. 5 ± 1. 2) min,(112. 7 ± 51. 0) vs. (270. 2 ± 89. 3) mL,(1. 1 ± 0. 2) vs. (1. 8 ± 0. 7) times. The differences were significant. Conclusion Neotype controllability artificial nephrohydrosis can develop renal tract for PCNL effectively.
ABSTRACT
Background: The association between isolated mild external ear malformations and urinary tract anomalies has not been sufficiently researched, and prevalence of renal abnormalities reported in different studies is controversial, which is the subject of considerable debate, currently causing confusion over which specific ear anomalies do and do not require imaging. Therefore, we examined this controversial issue by conducting a meta-analysis to asses the association of renal tract abnormalities in infants with isolated mild external ear malformations. Methodology: A meta-analysis of all published case-controlled studies, published in all languages. 65 artic1es were found, but only 4 were relevant. Main outcome measure was prevalence of urinary tract abnormalities detected by ultrasonography. Four studies involving 32983 evaluable infants were identified. The combined results indicated that the risk. in a fixed effects model, of renal tract anomalies in infants with isolated mild external ear malformations was O,R 1.56 (950/0CI1.25-1.94) Conclusions: This meta-analysis confirms a significant association between renal tract abnormalities and isolated mild external ear malformations.
Antecedentes: La asociación entre anomalías del tracto urinario y malformaciones moderadas del oído externo no ha sido suficientemente investigad. La prevalencia de anomalías del tracto urinario informadas en diferentes estudios, presentan resultados controversiales, lo cuál es materia de considerable debate, causando considerable confusión sobre cuales anomalías específicas del oído externo deberían o no ser estudiadas mediante imágenes para descartar asociación con malformaciones del tracto urinario. Por esto revisamos este punto controversial de la literatura, realizando un meta-análisis para evaluar el grado de asociación entre anomalías moderadas del oído externo y malformaciones del tracto urinario. Metodología: Se realizó un meta análisis de todos los estudios de casos y controles publicados en todos los idiomas. De 65 artículos publicados, sólo 4 se consideraron relevantes. El resultado a medir fue la prevalencia de anomalías del tracto urinario detectadas por ultrasonido. Los cuatro estudios evaluados involucraban 32983 niños. Los resultados combinados indican que el riesgo de presentar anomalías del tracto urinario en niños con malformaciones moderadas del oído externo, en un modelo de efectos fijos, fue de un OR 1.56 (IC95% 1.25-1.94) Conclusiones: Éste meta-análisis confirma una asociación significativa entre malformaciones moderadas del oído externo y anomalías del tracto urinario.
