Complications of endoscopic surgical treatment of upper urinary tract urolithiasis

Urolithiasis is one of the most common pathological conditions in the world, it is registered in 5-15% of the population. In Ukraine, urolithiasis accounts for 30-40% of all urological diseases. In the Odessa region, the prevalence of urolithiasis is one of the highest in Eastern Europe, exceeding 10.0%, the prevalence is particularly high in rural areas of Bessarabia and Budjaka. Percutaneous nephrolithotomy is considered the “gold” standard for the treatment of nephrolithiasis.

The study was conducted on the basis of the Center for Reconstructive and Reconstructive Medicine (University Hospital) ONMedU (Odessa) from 2017 to 2018. The results of endoscopic interventions in 181 patients regarding the calculi of the upper urinary tract were analyzed. The patients were between the ages of 20 and 78, the average age was 49.5±2.6, of which 54.2% were men and 45.8% women. PNLT was performed by 17.8% of patients with coral-like nephrolithiasis, 40.7% of patients with multiple (two or more) calculi and 41.5% of patients with single calculus of the pelvis-pelvis system

The incidence of intraoperative and postoperative complications was assessed by the classification of surgical complications of Clavien-Dindo: I degree of complications was observed in 17.6% of cases; II degree of complications was observed in 9.3% of cases; Grade III complications were observed in 5% of cases; IV degree of complications was observed in 2.8% of cases; V degree of complications - 0 cases (death of the patient).

Thus, the incidence of operative complications was 34.8% of these in-operation - 19.3%; postoperative - 15.5%

According to the Clavien-Dindo classification, complications were observed in 17.6% - I grade; 9.3% - II steps; 5% - III steps; 2.8% - IV degree; 0 - V steps.
