The invention relates to medicine, in particular to surgery, and can be used after operations on the upper urinary tract, especially when conserving surgery about Staghorn calculi stone.

Studies on patent and scientific and medical literature revealed the way in which in the postoperative period regarding pathologies of the upper urinary tract drainage is carried out through the lumbar region and set directly to the venue operations [1].

The method has the following disadvantages.

In the first place. Patients by the end of the second hour post-operative period there was a strong pain that makes use of narcotic analgesics.

Secondly. Patients wound on drainage continues until 5-6 days, with the first day of the postoperative period, the number of wound least, and the transition gemorragticheskogo content in serous starts with 4-5 days.

In third. In the postoperative period in a larger number of patients are septic and bronchopulmonary complications.

Above mentioned disadvantages can be eliminated in the proposed solution.

The objective of the invention is to improve the efficiency and reduction of post-operative disease in the pathology of the upper urinary what's ways.

This object is achieved by a combination of paravertebral procaine blockade through the vagina m.erector.trunci with subsequent drainage of the retroperitoneal space through the projection Petitou triangle in relation to the 12th rib.

A practical method is as follows.

At the end of key stage operations on the upper urinary tract, focusing on the lower edge 12 of the ribs, palpation define the edge m.erector.trunci and transverse process I of the lumbar vertebrae. Then the dotted line in the vagina m.erector.trunci needle with a syringe with anesthetic 0.25% solution of novocaine, this weight is distributed on the vagina muscles to level 12 of the rib to the transverse process II lumbar vertebra with capture nerves of the lumbar plexus by penetration to intervertebrale the outlet of the nerves. Further, by setting the projection Petitou triangle in relation to the 12th rib, and the end of the 12th rib is as a reference to a line drawn vertically to the wing of the Ilium at 1-2 cm above the wing of the Ilium, peelable lumbar region and we get to a lateral edge of m.iliopsoas that forms in this area of the lower edge of pojasnichno-iliac fossa. This site retroperitoneal space is the boundary between the lumbar region and the cavity of the pelvis, in this area due to the physiology m is chiyogami ways and the position of the patient expires postoperative bleed and have exudate wounds of the injured area of the kidneys and urine, also in this plot accumulate retroperitoneal hematoma. Put drainage with subsequent holding it up in the course of the wound to the initial parts of the urinary tract allows for active aspiration, for example an electric or mechanical pump, remove the contents of wound exudate, with an increase in intraperitoneal pressure to reduce the size of the retroperitoneal space by squeezing exudate in this area.

The method is illustrated by the following examples.

Among the 53 patients studied" the group claimed method was conducted on 28 patients, while 25 patients ablative surgery conducted without paravertebral procaine blockade and without active selective drainage of the retroperitoneal space through Petitou triangle. Two "researched" group approximately matched in equal proportions by age from 35 to 55 years of age and sex composition: in the first group of men in 53.6%of women of 46.4%, and in the second group to 53.1% and 46.9%, respectively.

Clinical results of the applied method can be assessed as good, which is supported also by the results of observations, reflecting the improvement in the postoperative course of the disease in patients in tables 1, 2 and graph.

The proposed method improve the postoperative course of the disease with surgery of the upper urinary tract, namely Staghorn calculi stone, does not require special technical and medical supply, is easily observed in the surgical hospital at any level and improve the results of the postoperative treatment of disease.

The way to improve the postoperative course of the disease with operations in the upper urinary tract, including drainage, characterized in that the end of the main phase of the operation do paravertebrally blockade, puncture vagina m.erector trunci, and the subsequent drainage of the retroperitoneal space is done by entering the drainage to the lateral edge of the m.ilipsoas through the puncture lumbar region of 1-2 cm above the wing of the Ilium on the line drawn through the end of the 12 ribs vertically to the wing of the Ilium.
