Due to some pathologies, injuries or surgical interventions, urine output may be impaired. This condition needs immediate correction. Various techniques are used for this, including stenting of the ureter. The essence of this minimally invasive surgical procedure is to install a special stent in the ureter, restoring the normal outflow of urine.
As a rule, stenting of the ureter is performed when this procedure is indispensable. In addition, this operation is considered quite simple. For these reasons, stenting has practically no contraindications. However, in the case of a severe injury to the ureter, a pronounced inflammatory process, as well as the patient's pregnancy, the decision on the possibility of performing the procedure is made by the doctor on an individual basis.
Before performing stenting, the doctor must make sure that the diagnosis is correct, confirm the feasibility of the operation, and exclude possible contraindications. Also, during the preparation for the operation, the specialist will select the optimal length of the stent.
For differential diagnosis, the doctor may prescribe excretory urography - intravenous administration of a radiopaque substance to assess the dynamics of its excretion by the kidneys.
Avoid alcohol 2 days before the procedure. On the day of the operation, hunger is shown from 00:00 hours. To remove gases and clean the walls of the intestines, make a cleansing enema. An antibiotic is prescribed to prevent post-procedure infection. Before manipulation, you need to empty the bladder for free access to the cystoscope.
There are 2 ways to install a ureteral stent - retrograde transurethral and antegrade transfistula. Retrograde - the introduction of a stent through the urethra and bladder using an endoscope tube with a video camera and a wire guide.
For a better view, the bladder is filled with a sterile solution. To select the correct insertion depth, a measuring scale is applied to the stent. After installation, the fluid is pumped out, and the endoscope is removed. The duration of the intervention is 30 minutes.
If there are no negative reactions and complications, then the stent is removed at least 2 weeks and maximum 6 months after installation - when the urinary structures take a physiological position and there will be no need for a stent. If lifelong use is necessary, then every 3-4 months it is changed to a new one in order to prevent urological infection, clogging of urine salts, mucosal damage and the formation of bedsores.
Before the removal procedure, diagnostics are carried out, as well as before installation. The stent is removed under local anesthesia using an endoscope. The duration of the procedure is 5 minutes. Within a few days after the manipulation, discomfort during urination is normal.
