[DRAINLESS TRANSCUTANEOUS NEPHROLITHOTRIPSY. OUR FIRST EXPERIENCE].

Experience of performance of a drainless transcutaneous nephrolitotripsy (DTN) for renal concrements was summarized. In 245 patients mini—DTN was done, оperation was finished with the nephrostomic drain installation — in 224 (91.4%), and without such procedure — in 21 (8.6%), in these patients an ureteric JJ—stent was installed in antegrade fashion. Indications for the DTN performance were substantiated, the patients for such treatment were selected, peculiarities of the DTN performance are adduced. JJ—stents were removed from ureter on the 2—nd — 7—th postoperative day, and in some patients — in ambulatory setting. After the operation the patients with out nephrostomic drain needed anesthesia in twice rarely. DTN constitutes a secure procedure, which must be conducted by experienced surgeon, сomplient with all demands and criteria of renal transcutaneous surgery, what permits to reduce the pain syndrome severity in patients in the early postoperative period stationary state.
