Comparison of laparoscopic ureterolithotomy and retrograde lithotripsy in the treatment of proximal ureteral stones

Abstract

The current approach in the surgical treatment of ureteral calculi involves the use of endourological procedures such as retrograde ureteroscopy with lithotripsy or percutaneous antegrade lithotripsy in the proximal ureter. Ureterolithotomy as a treatment method is of an auxiliary nature and is used when endourological intervention is impossible or in case of intraoperative collisions during access conversion. However, there are several comparative studies on lithotripsy and lithotomy.The aim. Comparative analysis of the outcomes of laparoscopic lithotomy and retrograde lithotripsy in the surgical treatment of proximal ureteral calculi, as well as the search for predictors of prolonged disability.Materials and methods. A prospective randomized multicenter study included 53 patients with an established diagnosis of ureterolithiasis who were treated in the period 2018–2021 in urological hospitals in Irkutsk. All patients were divided into two comparison groups: Lithotomy group (group 1; n = 30) and Lithotripsy group (group 2; n = 23).Results. When analyzing the results of the study, it was found that the level of complications of class II–III according to Clavien – Dindo was statistically comparable in both groups (p > 0.05). However, in absolute and relative terms, the prevalence of this indicator was noted during retrograde ureterolithotripsy. According to hard endpoints (reoperation, presence of residual stones or migration during the operation), 29 (96.6 %) patients of group 1 and 17 (73.4 %) patients of group 2 (p = 0.514) were successfully operated on.Conclusion. Laparoscopic ureterolithotomy may be offered to patients with large proximal ureteral stones as an alternative treatment option with better residual stone freedom but generally similar overall outcomes and complication rates.
