Due to some pathologies, injuries or surgical interventions performed, urine output may be impaired. This condition needs immediate correction. For this, various techniques are used, including stenting of the ureter. The essence of this minimally invasive surgical procedure is to place a special stent into the ureter, which restores normal urine flow.
As a rule, ureteral stenting is performed when this procedure is indispensable. Moreover, this operation is considered to be quite simple. For these reasons, stenting has practically no contraindications. However, in the case of severe trauma to the ureter, a pronounced inflammatory process, as well as the patient's pregnancy, the decision on the possibility of 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 expediency of the operation, and exclude possible contraindications. Also, during the preparation for the operation, the specialist will select the optimal stent length.
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.
2 days before the procedure, they refuse alcohol. On the day of the operation, hunger is shown from 00:00. To remove gases and cleanse the intestinal walls, a cleansing enema is given. To prevent post-procedural infection, an antibiotic is prescribed. Before manipulation, you need to empty the bladder for free access of the cystoscope.
There are 2 ways to install a ureteral stent - retrograde transurethral and antegrade transfistula. Retrograde - insertion of a stent through the urethra and bladder using an endoscope tube with a video camera and a string guide.
For a better view, the bladder is filled with a sterile solution. To select the correct insertion depth, there is a scale on 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 later and maximum 6 months after installation - when the urinary structures assume 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 with urine salts, damage to the mucous membrane 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 normally possible.
