Is retrograde stenting more reliable than antegrade stenting for pyeloplasty in infants and children?

A Modified Antegrade Stenting Technique for Laparoscopic Pyeloplasty in Infants and Children

“…Antegrade stenting can also be performed in 2 different ways such as; internal DJ stent and external pyelo-nephroureterostomy tube placement. There are numerous publications assessing the effectivity of those 3 main approaches [11,12,13,14,15,16]. It has been shown that despite their own advantages, many of those techniques have some drawbacks.…”

One day hospitalization after open, double-J stented pyeloplasty

“…Traditional transanastomotic nephrostomy tube drainage of the kidney has been replaced by JJ catheter stenting of the ureter to drain pediatric pyeloplasty. [1][2][3] Although nonstented pyeloplasty has been used in pediatric patients with similar results to stented pyeloplasty, [4,5] JJ catheter drainage can shorten hospital stay and reduce nursing care requirement. [2] Pediatric patients who underwent JJ catheter stented pyeloplasty for UPJ obstruction showed similar rate of complications compared to nonstented pyeloplasty (12% vs. 14%), while more infections and secondary procedures were seen in the nonstented group.…”

Antegrade stenting in laparoscopic pyeloplasty: feasibility of the technique and time required for stent insertion

“…This currently is the technique of choice for most surgeons involved in the laparoscopic treatment of UPJ obstruction [3,[8][9][10]. Chandrasekharam [13] supports the retrograde stenting technique based on his experience of 14/17 successful antegrade stenting (82%) and 24/25 (96%) successful retrograde stenting.…”

“…Nevertheless, few reports have focused on the results of this surgical step during laparoscopic pyeloplasty [12][13][14].…”

“…Moreover, in a recent paper, we showed that antegrade stent placement results also in a significantly faster overall operative time than retrograde stent placement [11]. Nevertheless, few reports have focused on the results and time required for insertion of the stent during laparoscopic pyeloplasty [12][13][14].…”
