Supracosteal drainage-free nephrolitotripsy: the experience of our center

Introduction. The use of supracosteal access when performing ITP provides the easiest access to the upper calyx and is recommended in the presence of complex kidney stones.Purpose of the study. Identification of the safest and most effective approach to the implementation of PTDTs and determination of indications for unpaired PTDTs. Materials and methods of research. A retrospective analysis of the case histories of 56 patients who underwent supra-rib PNLT in the urological department of ChUZ "KB" RZD-Meditsina "in Krasnoyarsk from January 2018 to December 2022 was carried out. Drainage-free PNLT was performed in 42 patients out of 56 (75 %). In all cases, supracosteal access was performed, and in 20 patients, a second working channel was additionally formed in a standard position below the XII rib.Treatment results. We evaluated the efficacy of PNLT for two groups of patients: the supracostal group without nephrostomy and the supracostal group with established nephrostomic drainage at the end of operative treatment. The results showed that the SFR for the supracostal group without nephrostomy was 90 %, while in the supracotsal group with external drainage this figure was 64 % (p function show_eabstract() { $('#eabstract1').hide(); $('#eabstract2').show(); $('#eabstract_expand').hide(); }
