The article presents results of extracorporeal shock wave lithotripsy (ESWL) in 62 patients with urolithiasis of a solitary kidney. In 50 (80.6%) patients calculi were located in the kidney and in 12 (19.4%) patients in the ureter. Effectiveness of ESWL at 3 month follow-up was 85.5%, which is somewhat lower than in patients with two healthy kidneys due to the choice of sparing low-energy modes of lithotripsy. The effectiveness of ESWL depended on the size of the original calculi (p<0.0001), and the baseline urodynamics of the upper urinary tract (p<0.0001). The rates of complications (32.3%) and auxiliary procedures (16.1%) were relatively low, due to the usage of pre-drainage of the kidney before a session of ESWL in patients with large and multiple calculi. There was no correlation between the occurrence of complications during treatment and the clinical form of a solitary kidney (p>0.05). In patients with stones larger than 1 cm and a moderate baseline abnormalities of the upper urinary tract urodynamics ESWL was less effective (p<0.0001), they had increased time of lithotripsy (p=0.013), more sessions (p<0.0001), complications (19.4%, p=0.043) and auxiliary manipulation (9.7%). Nevertheless, the duration of stay in hospital in the postoperative period did not correlate with the size of calculus (p=0.504). Extracorporeal shock wave lithotripsy is a highly effective and safe treatment of stones of a solitary kidney. Rational choice of indications and contraindications for the use of ESWL in a specific clinical situation is of great importance.
