Congenital obstruction of the upper urinary tract is often caused by the pyeloureteral junction syndrome, the lower polar vessel being the most common extrinsic etiology. We report on a case that was successfully treated using the Vascular HITCH, an alternative method with lower morbidity than Anderson and Hynes pyeloplasty considered the gold standard procedure. Our objective is to outline the aforementioned method and illustrate its ease of use and possible efficacy in carefully chosen adult patients.

Despite its high efficiency and low complication rate, there are ongoing studies which study the modification of the procedure using open, laparoscopic, and robotic approaches.
Aim: To describe a modified pyeloplasty technique with an assessment of the anatomical and functional results in comparison with the Anderson-Hynes procedure.

Article Synopsis
- The study aimed to explore how fibrosis-related genes in obstructed ureteral tissue relate to renal damage markers and preoperative renal scans.
- Researchers collected urine and blood samples pre-surgery, analyzing various biomarkers and gene expressions from obstructed tissue samples.
- The results showed certain negative correlations between urinary albumin and expressions of TGFβ1 and VEGFA in the obstructive tissue, but overall, no direct links were found between gene expressions and renal damage biomarkers.

Article Synopsis
- Newborn hydronephrosis is primarily caused by blockage at the pyeloureteral junction, potentially leading to serious complications like early kidney failure.
- A case study discusses a male neonate who successfully received Anderson-Hynes pyeloplasty to treat hydronephrosis in one kidney, emphasizing the importance of timely intervention.
- The study highlights the use of percutaneous nephrostomy for initial treatment and explores optimal timing for surgery to improve clinical outcomes in pediatric patients.
