title: [FEATURES OF PERCUTANEOUS NEPHROLITHOTRIPSY IN PATIENTS WITH UROLITHIASIS OF SOLITARY KIDNEY].
abstract: 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<0.0001), and the length of postoperative hospital stay (p<0.0001). Complications were common (44.9%), but the auxiliary manipulations were performed infrequently (26.5%). No associations were found between the size of calculus, the number of complications and secondary manipulations (p=0.361). No correlations were found between the clinical form of a solitary kidneywith urolithiasis and the occurrence of complications during the treatment course (p=0.121), as well as between the presence of complications and the cause of the "loss" of the contralateral kidney (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.
