“…For this reason, we prefer an anterior trans-peritoneal approach [27,28]. After a VH, the hospital stay is usually shorter compared to Anderson Hynes DP with a median length of 2 days [24,25,29]. In our sample, the hospital stay was shorter in patients who had undergone Hellstrom VH compared to those subjected to dismembered or non-dismembered pyeloplasty (respectively, 2 vs. 6 days).…”

“…Open Anderson-Hynes DP has always been considered the gold standard both for intrinsic and extrinsic UPJO with success rates of more than 90% [10]. In the last decade, many authors have wondered whether Hellstrom VH can be considered a valid alternative to DP in presence of CV [12,16,24,25], considering the advantages of this technique: surgical repair without opening the collecting system, leaving the UPJ intact, eliminating the risk of leakage or urinoma and preserving the pyelo-ureteral motility peristalsis. This procedure avoids the technical challenge of pelvi-ureteric anastomosis with a low complication rate and operative time [25,26].…”

Evaluating if the crossing vessel is obstructing the UPJ or it is only located near it without any functional compression is not mathematically possible.…”

Purpose Uretero-pelvic junction obstruction is the most common cause of prenatal hydronephrosis. It can be intrinsic, extrinsic due to crossing vessel (CV) or mixed. This paper aims to present the surgical outcome in a single pediatric thirdlevel center. Methods A retrospective analysis of all children operated between 2011 and 2018 was conducted. Demographic information, pre-operative pelvic antero-posterior diameter (APD), intra-operative parameters, hospital stay and follow-up were considered. Re-do operations and success rate for Vascular Hitch (VH), open and laparoscopic pyeloplasties were recorded. Results 128 patients were included. The mean pre-operative APD was 30 mm. The etiology was intrinsic in 71.9%, extrinsic in 25.0% and mixed in 3.1%. The median age between intrinsic and extrinsic groups was statistically different. Thirty-one VH, 88 dismembered and 9 non-dismembered pyeloplasties were performed. The median hospital stay was 2 days for VH and 6 for pyeloplasties. The median hospital stay was statistically longer in open pyeloplasties compared to laparoscopic. The mean post-operative APD was 14 mm. The success rate after VH was 90.3%, after open pyeloplasties 97.9% and after mini-invasive pyeloplasties 91.8%. Conclusions VH could be a good option in the treatment of hydronephrosis due to CV, laparoscopic pyeloplasties have equivalent success rate and shorter hospital stay than open pyeloplasties.

“…There are also extrinsic factors such as presence of crossing vessels and fibrous bands that may cause UPJO. [1] Although numerous studies investigating the molecular structures of obstructed segment have been performed, the principal mechanisms are still unclear. The abnormal nerve innervation patterns and abnormalities of collagen composition, reduction in interstitial cells of Cajal (ICs) and inflammation in the region of stenosis have been demonstrated in previous studies.…”

Is there a difference in the number of interstitial cells, neurons, presence of fibrosis and inflammation in ureteropelvic junction tissues of patients with ureteropelvic junction obstruction with and without crossing vessels?

Ureteropelvic junction obstruction (UPJO) is a common congenital abnormality that often presents in adulthood. Open dismembered pyeloplasty was considered the gold standard for the management of this condition; however, recent advancements in laparoscopic and robotic surgery have dramatically shifted the landscape to more minimally invasive techniques. A literature search of ureteropelvic junction obstruction, pyeloplasty, endopyelotomy, laparoscopic pyeloplasty, robotic pyeloplasty, and microlaparoscopic pyeloplasty was performed. A focus was placed on literature published since 2013. Minimally invasive laparoscopic and robotic techniques have become the gold standard for the management of UPJO. With the rise of robotic pyeloplasty, open repairs are becoming less frequent, while endoscopic treatments have remained stable. Minimally invasive (robotic) techniques have become the gold standard for the management of UPJO. Newer, even less-invasive techniques are also showing promise, but technical challenges still exist.
