Poliuria post-obstructiva. Análisis fisiopatológico de un caso

Valdivieso, Andrés J; Sepúlveda, Rodrigo A; Zúñiga, Álvaro.
Rev. méd. Chile; 151 (4), 2023
The relief of the impediment to urinary flow is the treatment of acute kidney failure due to urinary tract obstruction. However, there is a risk of inducing massive polyuria, which can be self-limited or produce severe contraction of the intravascular volume with pre-renal acute kidney failure and altera...

Mergudich-Thal, Tania; Pomés-Correa, Cristián; Francisco-Reyes, Ignacio San; Zamboni-Torres, Milena; Celle-Traverso, Claudia.
Rev. chil. obstet. ginecol. (En línea); 86 (5), 2021
INTRODUCCIÓN: La endometriosis ureteral es una afección rara que afecta al 0.01-1,7% de las mujeres con endometriosis. Hasta un 30% cursa de forma asintomática y un 11,5-14,7% pueden evolucionar con falla renal. La falta de diagnóstico de la enfermedad puede terminar en una uropatía obstructiva y fa...

MicroRNA-302b mitigates renal fibrosis via inhibiting TGF-β/Smad pathway activation

Sun, Mengkui; Zhou, Wei; Yao, Fei; Song, Jianming; Xu, Yanan; Deng, Zhimei; Diao, Hongwang; Li, Shoulin.
Braz. j. med. biol. res; 54 (3), 2021
Renal fibrosis is one of the most significant pathological changes after ureteral obstruction. Transforming growth factor-β (TGF-β) signaling pathway plays essential roles in kidney fibrosis regulation. The aims of the present study were to investigate effects of microRNA-302b (miR-302b) on ren...

The outcomes of mini-laparoscopic pyeloplasty in children - brazilian experience

Leonardo, Cristiane Reis; Muzzi, Alexandra; Távora, José Eduardo; Soares, Rodrigo Q.
Int. braz. j. urol; 46 (2), 2020
ABSTRACT Objetive Pelvicureteric junction (PUJ) obstruction is the main cause of hydronephrosis in childhood. Open pyeloplasty has been the gold standard treatment of this condition with success rate above 90%. The role of laparoscopic pyeloplasty (LP) in children is less well defined and has slowly em...
