METHOD FOR PREVENTION OF CICATRICAL-SCLEROTIC COMPLICATIONS FOLLOWING SURGICAL MANAGEMENT OF UPPER URINARY TRACT Russian patent published in 2015 - IPC A61B17/03 A61N1/36 A61N5/67 A61N7/00 A61K38/51 A61P13/02 

FIELD: medicine.

SUBSTANCE: method involves a combination of therapeutic-preventive measures involving drainage of an upper urinary tract by a percutaneous puncture nephrostomy, an antibiotic prevention, a physiotherapeutic exposure and 10 intramuscular injections of Longidase 3,000 International Units once every three days. On the following day after a drain tube is inserted, the course of an external magnetic-laser therapy consisting of 10 procedures starts. On the 7^th day following the nephrostomic drain tube insertion, the course of a multi-channel electric stimulation (ME) with bipolar pulse currents with trapezoidal envelope frequency 1-150 Hz, pulse train and pause 2 sec. The exposure covers trapezius and broadest muscle of back, rectus and oblique abdominal muscles. The exposure length is 15-20 minutes. The ME is combined with ultraphonophoresis of Longidase 3,000 IU in a projection of the involved ureter at intensity 0.2 Wt/cm² in the continuous mode unstably. The therapeutic course makes 10-12 combined daily procedures. On completion of all the physiotherapeutic procedures, the nephrostomic drain tube is clipped. The drain tube is first clipped for 2 hours a day during 3 days, then for 6 hours during 3 days. Then if an amount of residual urine does not exceed 30 ml, the drain tube is clipped for 24 hours during 3 days. If observing no complications, the nephrostoma is removed.

EFFECT: method ensures preventing the range of threatening complications by involving all links of mechanism of postoperative ureter stricture formation, including as a result of creating the high hyaluronidase concentration in paraurethral zone and restoring the ureter patency and peristalsis as fast as possible, and improving the urine passage.
