FEATURES OF PERCUTANEOUS NEPHROLITHOTRIPSY IN PATIENTS WITH UROLITHIASIS OF SOLITARY KIDNEY

: The article describes the results of percutaneous nephrolithotomy (PCNL) in 49 urolithiasis patients with a solitary kidney. In 44 (89.8%) patients the calculi were located in the kidney, in 5 (10.2%) patients - in the upper third of the ureter. The calculi were single (18; 36.7%), multiple (14; 28.6%) or stag-horn (17; 34.7%). Efficiency of PCNL estimated immediately after surgery and at the end of the third month of observation was 75.5 and 93.9%, respectively. Stone size (p=0.594), the baseline state of urodynamics of the upper urinary tract (p=0.205) did not affect the renal clearance at PCNL. Enlargement of initial calculus size positively correlated with the number of required treatment sessions (p=0.013), duration of surgery (p 0.05). Thus, percutaneous nephrolithotripsy is a highly effective method modality of treatment of solitary kidney urolithiasis. Appropriate selection of indications and contraindications for PCNL, preoperative preparation, surgical technique, postoperative patient management are of great importance.
