Minimally invasive percutaneous nephrolitho-tripsy without nephrostomy

The study included 138 patients with solitary and multiple renal stones. All patients underwent minipercutaneous nephrolithotripsy. The frequency of complete removal of the stones was 98%. Intraoperative complications were not recorded. Postoperative complications were assessed by the modified Clavien system (Dindo-modified). Complications of 0 degree were recorded in 102 (71.8%) cases, II - 38 (26.7%), and IIIa - only in 2 (1.5%) cases. In 80 (56.3%) cases, the upper urinary tract were drained using catheter-stent with an outer excretion through the urethra (group 1), in 58 (40.9%) cases - using catheter-stent with extraction of ligatures for nephrostomy to the lumbar region (2 group). In 4 (2.8%) patients, operation was completed by nephrostomy (group 3). In group 1, the average period of postoperative stay was 3-5 days, in the 2nd group - 3-7 days, in the group 3 - 4-7 days. None of the groups did not require opioid analgesics. Clinical observation is presented. Postoperative complications: in 86 (68%) patients - 0 according to the modified Clavien system (Dindo-modified), in 40 (30%) - II, and only in 2 - IIIa. In 78 (56.5%) cases, the upper urinary tract was drained using catheter-stent with an outer excretion through the urethra, in 56 (40.6%) cases - using catheter-stent with extraction of ligatures for nephrostomy to the lumbar region. In 4 (2.9%) patients operation was completed by nephrostomy. The average postoperative stay was 7.3 days. No patient required the appointment of opioid analgesics.
