Bladder endoscopy yes – no anesthesia

Bladder endoscopy is a method for diagnosing and treating urinary tract diseases that are widely applied today. This is a technique to assess the causes and conditions of bladder – urethra diseases, thereby having a timely and effective treatment plan for the disease. Currently there are 2 endoscopic techniques: bladder endoscopy with anesthesia and non-anesthetic bladder endoscopy.

1. What is bladder endoscopy?

Bladder endoscopy is a procedure for the doctor to evaluate the lower urinary tract, including the bladder and urethra through an endoscopy machine. This method is performed using an endoscopic lens inserted into the bladder through the urethra fall. Your doctor can look directly at the endoscope or through a computer screen that displays an endoscopic image.

The duration of the procedure depends on the degree of complexity of the pathology. For mild conditions, simple treatment, the procedure is carried out only about 10-15 minutes.

Bladder endoscopy in which:

  • Diagnosis of the cause of symptoms of hematemia, in case of mass hematoma, hematoma recurs several times;
  • Screening, examination of bladder tumors, upper urinary tumors, urethra tumors or urine cell tests;
  • In cases where there are tumors in the pelvic area to survey the invasiveness, compression of the tumor with the bladder and ureter;
  • Follow-up after treatment of shallow bladder tumors (early stages);

  • Urinary disorders: urination, difficulty urinating, irritation of urination …;
  • Urinary tract infections recur several times;
  • Bladder increased activity, bladder nervous chaos;
  • Cases of unn controlless urination;
  • Diagnosis and treatment of interstitial cystitis;
  • Chronic pain in the pelvic area;
  • Bladder stenosis, urethra stenosis;
  • Bladder injuries;
  • Esaculation and blood;
  • Infertility due to obstruction;
  • Picking up foreign objects, small stones in the bladder;
  • Suspected ureteral and genital tuberculosis;
  • Bladder reflux – ureter, ureter cyst;
  • Bladder fistula – vagina or bladder fistula – intestines;
  • Abnormalities of the anoperative structure or structure of the lower urinary tract: bladder vesiclia, urethra vesiclia, urethral stones, bladder stones, foreign objects in the bladder…;

Contraint of bladder endoscopy

  • Acute urinary infections;
  • Allergy to the drug Lidocain;
  • Stenosis of the urethra is numerous;
  • Cases in which the person does not cooperate: does not tolerate pain, mental disorders,… (pain relief, pre-anaesthetic support).

2. Bladder endoscopic engineering procedure


  • Patients do not eat or drink from the night before the endoscopy;
  • The doctor may prescribe antibiotics to the patient before performing this procedure;
  • Urine sampling before bladder endoscopy;
  • For bladder endoscopy procedures with local anesthesia without fasting;
  • Notify your doctor if you are taking blood thinners such as warfarin, aspirin and ibuprofen.

2.1. Anesthesia bladder endoscopy

  • Analgesic for patients: inject painkillers to the patient before the procedure (Feldene, Mobic..), local anesthesia with Xylocain (usually gel) pumped through the urethra.
  • Patient position: obstetrics and gynecology position.
  • Examination: place the bladder endoscopy machine, give water and the bladder to check the condition of the bladder, urethra, two ureter holes.

2.2. Non-anesthetic bladder endoscopy

  • The patient is dressed in hospital clothes, lying in a back position on a flat bed, cleaned outside the urethra and the surrounding skin area.
  • The doctor applies the gel to the urethral opening and the endoscope so that the endoscopic lens enters the urethra more easily, reducing discomfort for the patient;
  • The doctor pushes the endoscope gently into the urethra, towards the bladder. Fluorescent solution is inserted through the secondary channel in the endoscope to fill the bladder slowly so that the doctor observes the mucosa of the bladder more easily;

Bladder endoscopy needs to be performed properly
  • The bladder endoscopy process lasts only for an interval of 5-10 minutes if only for the purpose of examination and observation inside the bladder. However, in the case of a doctor performing some other procedures such as taking a sample of biopsy tissue from the bladder mucosa, the bladder endoscopy time may be longer;
  • The endoscope pulls gently out. If the patient anatomy of the disease, the specimen will be sent for testing and must wait several days for hism hism hism hismable results.

3. Possible complications after bladder endoscopy

  • Bleeding during or after the procedure: you can see a small amount of blood at the first urination. Most women who perform a bioscopy during bladder endoscopy will see blood in their urine. The amount of blood flowing is usually very small. Paramedics can transfer water through a cathethe tube into the bladder to wash away the blood or to remove any remaining blood clots (also known as 'bladder washing').
  • Urinary tract infections: after an endoscopy you feel the need to urinate several times, and each time you urinate only a small amount each time accompanied by an unpleasant sensation, you may be suffering from a urinary infection. If these symptoms worsen, let your doctor know. You may need to treat this symptom with antibiotics.
  • Urethra stenosis: caused by scar tissue forming in your urethra. However, urethral stenosis is quite rare after the first bladder endoscopy. If this happens, you may need further surgery to correct it.

Urethral stenosis

  • Puncture of a hole in the bladder: if this happens, the doctor will place a cathetro in your bladder for a few days to let this hole heal. If the hole does not heal, you may need to be re-operated to fix it.
  • Bladder endoscopy is a technique commonly used in the diagnosis and treatment of a number of pathological conditions in the urinary tract. When performing this procedure, the patient should follow the instructions of the doctor to ensure the diagnosis efficiency, high accuracy and reduce the risk of complications.

If you have any questions about possible complications after a bladder endoscopy, consult your doctor for advice and answers.
