TY - JOUR ID - TI - Early Complications of Diagnostic and Therapeutic Ureteroscopy AU - Newar Mohammed Mahmoud, Shakir Saleem Jabali PY - 2018 VL - 15 IS - 1 SP - 93 EP - 98 JO - Medical Journal of Babylon مجلة بابل الطبية SN - 1812156X 23126760 AB - Objective: The aim of this study is to report early complications of diagnostic and therapeutic ureteroscopy and to grade each complicationaccording to modified Clavien classification system (MCCS). Materials and Methods: Through a prospective study conducted from March toSeptember 2017, all patients who underwent diagnostic and therapeutic semirigid ureteroscopy were evaluated. The procedure was performed bydifferent surgeons. The recording data included patient demographics, ureteroscopy site (left, right, or bilateral), aim of ureteroscopy (diagnosticor therapeutic), operative time, additional intervention, stone‑free rate, double J stent placement, and complications which were graded accordingto the modefied clavien classification system with their management. Results: One hundred and fifty patients were included in the study.The average age was 39.9 years and male‑to‑female ratio 2.3/1. The number of patients who underwent right, left, and bilateral ureteroscopywas 74 (49.3%), 64 (42.3%), and 12 (8%), respectively, so the overall number of ureteroscopy procedures was 162. Diagnostic ureteroscopywas done in 20 (13.3%) patients and therapeutic ureteroscopy in 130 (87.7%). Complications occurred in 37.3% of patients. According toMCCS, Grade I, II, IIIa, IIIb, IVa, IVb, and V complications were detected in 40 (26.6%), 6 (4%), 10 (6.7%), 14 (9.3), 0 (0.0%), 2 (1.3%), and0 (0.0%) of cases, respectively. Conclusion: Ureteroscopy becomes the prevailing procedure for different ureteral pathologies mainly stoneswith a good safety and efficacy. It is important to adopt a precise classification system for reporting the complications of ureteroscopy. Mostof the complications are of low grade and they are amenable to conservative management. The complications of ureteroscopy will continueto decline as the ureteroscopic technology evolved.
