“…These special features greatly facilitate the internal suturing of UC [ 49 ]. Previous studies have reported a success rate of > 90% for RALUC [ 14 , 27 , 41 , 50 ]. Additionally, the literature suggests that RALUC is the preferred option for patients with recurrent pelvic ureteral junction obstruction [ 42 ].…”

“…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.
