Abstract
Objectives
To review our experience with ureteroscopy (URS) in the treatment of ureteral calculi and stratify intraoperative complications of URS according to the modified Satava classification system.
Patients and methods
We performed a retrospective analysis of 1,208 patients (672 males and 536 females), with a mean age of 43.1 years (range 1–78), who underwent ureteroscopic procedures for removal of ureteral stones. Intraoperative complications were recorded according to modified Satava classification system. Grade 1 complications included incidents without consequences for the patient; grade 2 complications, which are treated intraoperatively with endoscopic surgery (grade 2a) or required endoscopic re-treatment (grade 2b); and grade 3 complications included incidents requiring open or laparoscopic surgery.
Results
The stones were completely removed in 1,067 (88.3 %) patients after primary procedure by either simple extraction or after fragmentation. The overall incidence of intraoperative complications was 12.6 %. The most common complications were proximal stone migration (3.9 %), mucosal injury (2.8 %), bleeding (1.9 %), inability to reach stone (1.8 %), malfunctioning or breakage of instruments (0.8 %), ureteral perforation (0.8 %) and ureteral avulsion (0.16 %). According to modified Satava classification system, there were 4.5 % grade 1; 4.4 % grade 2a; 3.2 % grade 2b; and 0.57 % grade 3 complications.
Conclusion
We think that modified Satava classification is a quick and simple system for describing the severity of intraoperative URS complications and this grading system will facilitate a better comparison for the surgical outcomes obtained from different centers.
