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

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...

Effects of Rab7 gene up-regulation on renal fibrosis induced by unilateral ureteral obstruction

Braz. j. med. biol. res; 53 (4), 2020
Rab7, an important member of the Rab family, is closely related to autophagy, endocytosis, apoptosis, and tumor suppression but few studies have described its association with renal fibrosis. In the early stage, our group studied the effects of Rab7 on production and degradation of extracellular matrix i...

Simulated training model of ureteropyelic anastomosis in laparoscopic pyeloplasty

Acta cir. bras; 35 (11), 2020
Abstract Purpose: To develop a model for simulated training of ureteropyelic anastomosis in laparoscopicpyeloplasty. Methods: Longitudinal and experimental study, with 16 participants. A synthetic instrument was produced to simulate the renal pelvis and the proximal portion of the ureter positioned on ...

Ureteropelvic junction obstruction caused by metastatic cholangiocarcinoma

Int. braz. j. urol; 45 (6), 2019
ABSTRACT We describe the rare case of a 61-year-old female with right ureteropelvic junction (UPJ) obstruction caused by metastatic cholangiocarcinoma. Her past medical history was notable for cholangiocarcinoma treated with neoadjuvant chemoradiation and two orthotopic liver transplants six years earlie...

Comparison of the outcomes of laparoscopic pyeloplasty with and without concomitant pyelolithotomy

Int. braz. j. urol; 45 (5), 2019
ABSTRACT Objective We aimed to evaluate the results of laparoscopic pyeloplasty with concomitant pyelolithotomy and compare results with a cohort of patients undergoing laparoscopic pyeloplasty without pyelolithotomy. Materials and Methods We retrospectively reviewed records of 43 patients undergoing...

Balloon dilation for failed pyeloplasty in children?

Int. braz. j. urol; 45 (3), 2019
ABSTRACT Objective: Pyeloplasty is considered the gold standard treatment for ureteropelvic junction obstruction (UPJO). However, the failure rate of pyeloplasty is as high as 10% and repeat pyeloplasty is more difficult. This study aimed to evaluate the efficacy of balloon dilatation for failed pyelopl...

The Effect of Tadalafil on Renal Fibrosis Induced by Ureteral Obstruction

West Indian med. j; 68 (2), 2019
ABSTRACT Objective: It has been reported that phosphodiesterase-5 (PDE-5) inhibitors improve kidney function during acute and chronic renal failure. This study aimed to determine the possible therapeutic effects of tadalafil, a specific PDE-5 inhibitor, on renal fibrosis induced by unilateral ureteral o...

Iatrogenic ureteral obstruction during transvaginal ocyte retrieval

Int. braz. j. urol; 45 (2), 2019
ABSTRACT Transvaginal oocyte retrieval is a crucial step in assisted reproductive technology. Various complications may arise during this procedure. Ureteral injury is a rare, but a serious complication in gynecological practice. During oocyte retrieval, ureteral injuries, detachment and obstruction can ...
