Experience and Performance of Tubeless Percutaneous Nephrolitotomy

Percutaneous nephrolithotripsy is a standard method in the treatment of nephrolithiasis, final stage which nephrostomy drainage established, but there are known methods performing this operation without nephrostomy. This article shows our experience tubeless percutaneous nephrolithotomy, as well evaluates safety and efficacy PNL with placement JJ-stent. The objective: establish opportunities to perform mini nephrolithotomy evaluate effectiveness its implementation. Materials methods. For period 2017–2021. performed more than 500 nephrolitotomy. 53 mini-PNL (II group), other group (I group) included 58 patients who underwent by method. There were no significant differences age sex, location size stones study groups (p>0,05). All operations under regional anesthesia. Results. average duration I was 57,2±17,9 minutes, II 54,9±15,6 minutes drop hemoglobin 0,39 g/l compared 4,1 group. difference between not statistically level pain assessed using visual analog scale, 3,7 1,6 (p<0,05). Accordingly, necessity analgesia for higher amounted 58,4±17,3 mg dexketoprofen, against 27,3±15,2 dexketoprofen second Postoperative fever ≥38,0 °С observed 5 (8,6%) according method, 1 (1,9%) patient (p>0,05) drainage-free PNL. stone free rate achieved 56 (96,6%), (100%) postoperative hospital stay 2,92±0,24 days, – 1,22±0,11 days Analyzing results we can say that due careful selection strict compliance rules Conclusions. demonstrates advantages over form reducing pain, need analgesics, reduces stay. However, it should be noted techniques strictly selected patients.
