Abstract:Purpose:
Ureterocalicostomy is a technique that was first described by Neuwirt in 1948 (
1
) The laparoscopic access was initiated in 2003 by Cherullo et al. (
2
), following the established principles of open surgery. In 2004, Gill et al. had two patients with UPJO treated with laparoscopic ureterocalicostomy, with success (

). In 2014, Arap et. al. presented a case series with good results in adults and children i… Show more
“…A radionuclide scan conducted 1 year after the surgery indicated that the bilateral renal function levels were comparable, ultrasound showed no remaining hydronephrosis, and the urinary flow of the affected kidney was unobstructed [ 38 ]. In two case reports [ 16 , 34 ], both patients underwent UC due to obstruction of the ureteropelvic junction following pyeloplasty. The operation was successfully performed, and postoperative follow-up results demonstrated significant improvement in hydronephrosis with no evidence of anastomotic obstruction.…”
“…However, with the continuous exploration of surgeons and the advancements in laparoscopic technology, laparoscopic or robot-assisted laparoscopic ureterocalicostomy (LUC or RALUC) has been increasingly performed on patients with severe hydronephrosis caused by complex upper ureteral stricture and obstruction. These procedures have shown satisfactory results [ 14 – 16 ]. A comprehensive search was performed using the PubMed database by entering the search term “ureterocalicostomy” to collect relevant studies on UC.…”
Upper ureteral stricture is a relatively rare but increasingly encountered condition in clinical practice. While simple stricture can often be addressed through endoluminal treatment or surgical reconstruction, complex upper ureteral stricture poses challenges, particularly in patients with ureteropelvic junction obstruction (UPJO) or perirenal pelvic fibrosis and scarring resulting from previous surgeries. These cases present difficulties for traditional endoluminal and ureteral reconstruction treatments, posing a significant problem for many clinical surgeons. Our study involved a thorough search and comprehensive analysis of the existing literature on Ureterocalicostomy (UC). The literature indicates that UC is a safe and effective treatment for ureteral stenosis. By resecting the renal lower pole parenchyma, it is possible to achieve mucosal anastomosis between the calyceal and ureteral mucosa, leading to the restoration of normal urinary excretion. This technique has emerged as an alternative for treating complex upper ureteral strictures. However, there is a lack of direct comparative studies between open surgery and minimally invasive surgery. Our findings revealed a scarcity of relevant review documents, with most being case reports or retrospective studies conducted in single centers with small sample sizes. Therefore, it is crucial to conduct large-scale, multicenter prospective studies and long-term follow-up to validate the long-term efficacy of UC. This article reviews the development history of UC and focuses on a comprehensive discussion of its indications, surgical techniques, and complications.

“…They are to be congratulated on their significant contribution to the field, understanding that such cases should only be completed in the setting of a clinical trial and by highly skilled minimally invasive surgeons, with a low threshold for open conversion if adequacy of surgical resection is at all felt to be compromised. The second prize for best video of the year is awarded to Nunes, et al from the University of São Paulo for their submission entitled “Laparoscopic ureterocalicostomy technique” published in volume 49, number 3 of our journal ( 2 ). As we all know, reconstruction using an ureterocalicostomy is infrequently completed by even experienced urologists so this publication using a minimally invasive approach and marvelously captured and described represents an invaluable resource for urologists and trainees.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
