FAQ

What are the surgical indications and contraindications of urological surgical instruments?

The indications and contraindications of urological surgical instruments are as follows:

Indications:
Prostatic hyperplasia: such as transurethral prostate expansion (PUL), suitable for patients with prostatic hyperplasia with a volume of 30-80mL.
Urethral stenosis: including superficial bladder cancer, invasive bladder cancer, etc.
Uterine fibroids, uterine polyps: suitable for surgical operations such as vaporization, cutting, ablation, coagulation, stripping and vascular closure of soft tissue.
Renal cystectomy: performed through two-port retroperitoneoscopic and laparoscopic techniques.
Testicular descent for cryptorchidism: can also be done through laparoscopy.
High varicocele ligation: also within the scope of laparoscopic surgery.
Urinary tract atresia, dysuria, recurrent hematuria, urinary tract infection, renal failure: these symptoms may require surgical intervention when medical treatment fails or financial difficulties occur.
Contraindications:
Acute infection: Surgery is not suitable when there is an acute infection in the urogenital system.
Hematological diseases, coagulation disorders: Such patients are not suitable for laparoscopic surgery.
Those who have not signed the consent form for surgery: This is one of the exclusion criteria, indicating that the patient must agree to the surgery before it can be performed.
Severe organ failure: The surgical risk of such patients is higher, and surgery is usually not recommended.
Lower urinary tract obstruction, allergic to product materials: For example, these conditions are clearly mentioned in the contraindications of disposable ureteral guide sheaths.
In addition, some specific contraindications are also mentioned in the instructions for use of specific instruments and equipment. For example, closure clips cannot be used as occlusion devices for fallopian tube contraception, nor can they be used for laparoscopic donor processing.

In short, the indications and contraindications of urological surgical instruments need to be evaluated in detail according to the specific disease and patient conditions, and strictly follow the relevant operating specifications and guidelines.

What are the specific indications and contraindications of urological surgical instruments in the treatment of prostatic hyperplasia?

The specific indications and contraindications of urological surgical instruments in the treatment of prostatic hyperplasia are as follows:

Indications:
Obvious prostatic hyperplasia syndrome: including bladder irritation symptoms and bladder outlet obstruction symptoms, such as frequent urination, dysuria, increased bladder residual urine volume and urine retention.
Poor drug treatment effect: When the patient still has obvious prostatic hyperplasia symptoms after drug treatment, surgical treatment can be considered.
Combined bladder stones: Bladder stones can induce hematuria and urinary tract irritation signs, which need to be treated by surgery.
Abnormal urine flow rate test: Patients with urine volume above 150ML and maximum urine flow rate less than 10ml/S are suitable for surgery.
Recurrent urinary tract infection: Due to prostatic hyperplasia, residual urine increases, increasing the chance of urinary tract infection, so surgical intervention is required.
Serious impact on quality of life: such as patients with significantly increased nocturia or particularly difficult urination.
Poor long-term medication effect: patients with poor long-term use of α-receptor blockers or 5α-reductase inhibitors.
Contraindications:
Systemic diseases: patients with cardiovascular and cerebrovascular diseases, severe hypertension, uncontrolled acute myocardial infarction, arrhythmia, etc. are not suitable for surgery.
Respiratory diseases: patients with severe bronchial asthma, emphysema and lung infection are not suitable for surgery.

What are the main instruments used in urethral stricture surgery and their indications and contraindications?

The main instruments used in urethral stricture surgery include urethral dilators, urethral probes, microscopic instruments, silicone catheters, etc. Among them, disposable urethral dilators are a common passive surgical instrument, which is mainly used to improve urethral stricture or obstruction by dilating the urethra.

In terms of indications, the treatment of urethral stricture is usually used as a first-line treatment method, which is suitable for urethral stricture caused by various reasons, such as trauma, sequelae of intracavitary surgery, indwelling catheterization, etc. Direct visual internal urethrotomy (DVIU) is the first-line treatment method for urethral stricture. According to different surgical instruments, it is divided into cold knife and hot knife.

In terms of contraindications, urethral stricture combined with urethral infection, periurethral abscess or urethral fistula is an absolute contraindication for internal urethrotomy, because when the urethral mucosa is cut, bacteria can enter the blood circulation from the incision, leading to bacteremia and even endotoxic shock. In addition, patients with acute urethritis or prostatitis should also avoid catheterization.

What is the best surgical method for uterine fibroids and uterine polyps, as well as their indications and contraindications?

The surgical methods, indications and contraindications for uterine fibroids and uterine polyps are as follows:

Uterine fibroids
Surgical methods
Abdominal surgery: including laparotomy and laparoscopic surgery.
Hysteroscopic surgery: suitable for submucosal fibroids.
surgery: suitable for patients without indications for laparotomy.
Indications
Submucosal fibroids: increased menstrual volume and prolonged menstruation affect embryo implantation.
Intramural fibroids: larger diameter, close to the uterine cavity, compression of the endometrium, resulting in abnormal endometrial morphology.
Ineffective drug treatment or recurrence after fibroid removal.
If the diameter of the fibroid is ≥4 cm when the patient is preparing for pregnancy, it is recommended to remove it.
Fibroids still grow without hormone replacement therapy after menopause.
Contraindications
Multiple intramural fibroids, uterus larger than 4 months of pregnancy, or intramural fibroids located in the deep layer, broad ligament fibroids protruding into the uterine cavity, fibroid diameter greater than 10 cm, adenomyosis or malignant transformation.
Uterine polyps
Surgical method
Hysteroscopic surgery: used to exclude inflammation and surgical contraindications. If inflammation is found, anti-inflammatory treatment should be actively given.
Indications
Exclude surgical contraindications: First do the corresponding laboratory tests to understand whether there are inflammation and surgical contraindications. If inflammation is found, anti-inflammatory treatment should be actively given. It can only be done after passing the reexamination.
Contraindications
It is necessary to exclude surgical contraindications, pay attention to the timing of surgery, prepare the well and have family members accompany you, and do postoperative care.

What are the specific conditions for the indications and contraindications of high varicocele ligation?

High varicocele ligation is a surgical method for treating varicocele, which has the advantages of less trauma and faster recovery. However, this surgery is not suitable for all patients and has certain indications and contraindications.

Indications:
Infertility: For patients with infertility caused by varicocele, especially those with abnormal semen examination and normal endocrine examination, and no abnormal findings in the female fertility examination, regardless of the severity of varicocele, as long as the diagnosis is established, surgery should be performed in time.
Infertility caused by testicular spermatogenesis dysfunction: If varicocele is accompanied by testicular spermatogenesis dysfunction causing infertility, surgery is required.
Inguinal hernia or hydrocele: Patients with inguinal hernia or testicular hydrocele also need surgery.
Contraindications:
Severe liver cirrhosis, severe ascites, hematopoietic dysfunction with severe bleeding tendency: Patients in these cases are not suitable for high varicocele due to the high risk of surgery.
Patients with a history of abdominal infection and open pelvic surgery with extensive adhesions: Such patients are not suitable for such surgery due to the risk of serious complications.
High ligation of the internal spermatic vein: In certain specific cases, such as high ligation of the internal spermatic vein, it may not be suitable.

For patients with lower urinary tract obstruction, which urological surgical instruments are advantageous and which are not recommended?

For patients with lower urinary tract obstruction, the use of the following urological surgical instruments is advantageous:

Laparoscopic or robotic-assisted techniques: These techniques can be used for the treatment of complex upper ureteral stenosis, such as ureteropelvic junction obstruction (UPJO), with renal pelvic valve plasty or lingual mucosal ureteroplasty. Renal pelvic valve plasty is recommended because of its simplicity and convenience. In addition, laparoscopic surgery has the advantages of shortening hospital stay, improving appearance, reducing postoperative pain and early recovery.

Transurethral surgery: including transurethral prostate vaporization (using green laser with a wavelength of 532nm), transurethral thulium laser/holmium laser enucleation (holmium laser with a wavelength of 2140nm and thulium laser with a wavelength of 810nm respectively). These laser surgeries are used to treat BPH and have the advantages of less trauma and faster recovery.

Ureteral stent: used to relieve ureteral obstruction, promote postoperative ureteral healing, and assist in identifying ureters during pelvic surgery. Although the placement of ureteral stents may cause a certain degree of complications, its application in the treatment of urinary obstructive diseases is effective.

Prostate stent: used to treat lower urinary tract obstruction caused by prostatic hyperplasia. Although the mesh metal stents used in the early days have certain short-term efficacy, over time, epithelial and prostate tissues grow rapidly into the stent, causing urethral problems. Therefore, choosing the right stent type and material is key.

Minimally invasive surgical therapy (MIST): including water jet therapy, prostatic artery embolization, water vapor ablation, transperineal laser ablation, etc. These minimally invasive surgical therapies are increasingly important in the treatment of lower urinary tract symptoms to avoid side effects and maintain function.

However, the results did not clearly indicate which urological surgical instruments are not recommended. However, it can be inferred that non-standard urinary system-related surgical operations and non-standard use of urinary tract instruments may damage the urinary system, thereby causing obstructive urinary tract disease. Therefore, following standardized operations and choosing appropriate surgical instruments are the key to avoiding adverse consequences.
