FAQ

What are the patient selection and evaluation criteria for urological surgical instruments?

The patient selection and evaluation criteria for urological surgical instruments involve multiple aspects, including the patient's clinical characteristics, comorbidities, surgical methods, and the experience of the surgeon. The following is a detailed analysis:

Patient selection criteria:

Age and health status: Patients are usually required to be between 30 and 70 years old, and the medical records are complete without missing items.
Disease conditions: Patients who require surgical treatment, such as recurrent low back pain, hydronephrosis with recurrent urinary tract infections, reduced renal function due to obstruction, and patients with previous surgical failures, should be evaluated in detail.
Comorbidities: Whether the patient has other major organ lesions or coagulation disorders is also an important consideration.
Patient preferences and acceptance: Patients' preferences for different surgical methods and the surgical-related side effects they can tolerate should also be considered.
Preoperative evaluation:

Imaging examination: All patients received urinary system ultrasound, intravenous urography, CT urography (CTU) or magnetic resonance urography (MRU) examinations before surgery. If necessary, retrograde urography or convex urography was performed to clarify the degree of hydronephrosis, the location and length of ureteral stenosis.
Functional test: The urinary function test (URODYN) can predict the treatment effect and help formulate a treatment plan.
G8 score: It is used to assess the health status of the elderly. Patients with a score greater than 14 should receive the same treatment as young patients, and patients with a score less than 14 should undergo a comprehensive evaluation.
Choice of surgical method:

Minimally invasive surgery: For benign prostatic hyperplasia (BPH), the American Urological Association (AUA) recommends selecting appropriate patients for minimally invasive surgery based on preoperative evaluation, such as percutaneous nephrolithotomy (PCNL) or robotic-assisted laparoscopic surgery (RARC).
Specific technical selection: The choice of surgical technique depends on many factors, including prostate size, comorbidities, anesthesia ability, patient preference, willingness to accept surgery-related side effects, available surgical instruments, and the experience of the surgeon.
Selection of equipment and instruments:

Robotic-assisted laparoscopic surgical instruments: including titanium clamps, laparoscopic cutting staplers, laparoscopic puncture kits, etc.
Percutaneous nephroscopic surgical instruments: including nephroscopes, rigid ureteroscopes, flexible ureteroscopes, flexible cystoscopes, hybrid lithotripsy systems, pneumatic ballistics, holmium lasers, etc.
Other commonly used instruments: such as bladder tumor forceps, percutaneous nephroscopic bladder biopsy forceps, urethral retractors, prostate retractors, etc.
Postoperative management:

Complication assessment: The Clavien-Dindo grading system is used to accurately reflect the severity of complications, help evaluate the safety of surgery and compare different surgical methods.
Accelerated recovery concept: The full-course nutrition management model and other accelerated recovery measures are applied to improve the patient's postoperative recovery speed.
Through the above-mentioned comprehensive evaluation and selection, the success of urological surgery can be ensured and the occurrence of postoperative complications can be reduced.

In urological surgery, which specific imaging examinations are most critical for diagnosing and evaluating the patient's condition?

In urological surgery, the following specific imaging examinations are most critical for diagnosing and evaluating the patient's condition:

Ultrasound examination: As a non-invasive imaging examination method, ultrasound is widely used in the diagnosis of urinary system diseases. It can help observe the lesions and occurrence sites of the urinary system, and provide important imaging basis for diagnosis, treatment and efficacy evaluation.

Computed tomography (CT) examination: CT examination forms cross-sectional or three-dimensional images through the different absorption and transmittance of X-rays by different tissues, which is used to observe the changes in the anatomical morphology of the examined organs, blood perfusion, etc. It has important value in the diagnosis of urinary system diseases, especially in the evaluation of kidney diseases, kidney stones, hydronephrosis, etc.

Magnetic resonance imaging (MRI) examination: MRI can provide detailed soft tissue structure images, which is of great value for the diagnosis and evaluation of various diseases in the urinary system (such as kidney tumors, bladder cancer, etc.).

Excretory urography (IVP): IVP is a traditional imaging method that observes the structure and function of the urinary tract system by injecting contrast agents. It is particularly suitable for diagnosing complex urinary tract diseases.

CT urography (CTU): CTU uses multi-slice spiral CT to perform whole urinary tract imaging and post-processes and reconstructs the obtained images. It is used to diagnose various urinary system diseases, especially in the diagnosis of congenital kidney and urinary tract malformations in children.

What are the latest technological advances or emerging tools that have proven to be effective when choosing a urological surgical procedure?

When choosing a urological surgical procedure, the latest technological advances and emerging tools include:

Potassium titanium phosphate laser technology: This is a medical laser technology used in various urological surgical procedures. It produces green light energy at a wavelength of 532 nanometers and is specifically designed for precise and controlled tissue vaporization.

Domestic Kangduo laparoscopic robotic surgery system: The system attempted the world's first remote animal surgery based on 5G network in 2018, and successfully implemented the world's first multi-point collaborative 5G remote animal surgery in 2019. The new generation of products further optimizes the eyepiece adjustment function to meet the needs of different surgical positions.

Holographic imaging technology: Beijing United Family Urology Team introduced holographic imaging technology into urological surgery as early as 2017, and completed the world's first "robotic testicular cancer chemotherapy retroperitoneal lymph node dissection" surgery combined with holographic imaging.

Rezūm thermal steam ablation, transurethral prostate expansion (Urolift), high-energy focused ultrasound technology (Hifu): These new technologies are changing the traditional prostate treatment model, providing more options and better efficacy.

Robotic surgery technology: In recent years, as an important part of micro-innovation technology, robotic surgery has rapidly changed the traditional diagnosis and treatment model in the field of urological tumor surgery, improving the accuracy and safety of surgery.

How to choose the most appropriate minimally invasive surgical technique according to the patient's specific conditions (such as age, gender, comorbidities, etc.)?

Choosing the most appropriate minimally invasive surgical technique requires comprehensive consideration of the patient's specific conditions, including age, gender, comorbidities, etc. The following is a detailed analysis of the data:

Location and size of the tumor:

The best way to remove the specimen can be determined based on the location and size of the tumor. For example, in colorectal cancer surgery, laparoscopy, robotics, anal endoscopic minimally invasive surgery or soft endoscopy can be selected to remove the specimen.
Patient's gender and age:

Gender and age are important factors affecting surgical selection. For example, in partial nephrectomy, factors such as gender, age, and BMI will affect the change in GFR of the affected kidney after surgery.
In thyroid surgery, MIVAT is suitable for young patients without obvious neck scars and BMI less than 30 kg/m^2, while PTC is more suitable for patients with a history of nodules or obesity.
Comorbidities:

Comorbidities are also an important reference for choosing surgical methods. For example, in patients with prostatic hyperplasia and ureteral stones, the effects of minimally invasive surgery on prostate symptoms and function were studied at the same time.
In patients with hypertensive intracerebral hemorrhage, the efficacy and quality of life effects of small bone window minimally invasive surgery and large bone flap craniotomy were compared. The results showed that there was no statistically significant difference in general clinical data such as gender, age and bleeding site between the two groups.
Other factors:
Other factors such as tumor nature, surgical procedure, approach, intraoperative blood loss, occlusion time, ice water cooling, etc. can also affect the choice of surgery.
In minimally invasive surgery for bilateral chronic subdural hematoma, the patient's gender, age, and hematoma site were also recorded and analyzed.
The selection of the most appropriate minimally invasive surgical technique requires a comprehensive assessment based on the patient's specific situation, including the location and size of the tumor, the patient's gender and age, comorbidities, and other relevant factors.

What are the application criteria of the Clavien-Dindo grading system in the management of complications after urological surgery?

The Clavien-Dindo grading system is a tool widely used in the management of complications after urological surgery. Its application criteria are as follows:
Classification principle: This system not only quantitatively evaluates postoperative complications, but also qualitatively evaluates them based on the severity of complications. It provides guidance on the type and amount of medical intervention that needs to be taken.
Grading content:

Level 1 (Grade): Any deviation from the normal postoperative course that can be resolved without drug therapy or surgical, endoscopic and radiological intervention.
Level 2 (Grade): Requires drug therapy or simple surgical, endoscopic and radiological intervention.
Level 3 (Grade): Requires more complex surgical intervention.
Level 4 (Grade): Requires care in the intensive care unit (ICU).
Level 5 (Grade): Leads to death or requires emergency life support measures.
Scope of use: The system is recommended for evaluating the safety of surgery, comparing different surgical methods, and analyzing the learning curve of surgical techniques.

Global recognition: Since it was proposed by R.A. Clavien et al. in 1992 and improved by D. Dindo et al. in 2004, the system has been recommended by the European Association of Urology (EAU) and has been widely used worldwide.

How is the application effect of the concept of accelerated recovery after urological surgery, and what empirical studies support its effectiveness?
The application effect of the concept of accelerated recovery after urological surgery (ERAS) is significant, and multiple empirical studies support its effectiveness.

The concept of accelerated recovery can significantly reduce the risk of postoperative complications, speed up wound healing, shorten hospital stay, and improve the quality of life of patients. For example, in laparoscopic urology upper urinary tract surgery, the application of the concept of accelerated recovery surgery can effectively reduce the patient's physical and psychological trauma stress, thereby achieving the purpose of accelerated recovery.

Specific studies have shown that the application of the concept of accelerated recovery surgery in the perioperative period of laparoscopic urology can significantly shorten the patient's hospital stay, reduce the incidence of complications, and improve patient satisfaction. By optimizing various links such as preoperative preparation, intraoperative management, and postoperative rehabilitation, the patient's recovery process can be accelerated and the consumption of medical resources can be reduced.

In addition, the application of accelerated recovery nursing in the management of day surgery in urology has also shown good results. Compared with the traditional medical care model, the ERAS nursing concept can better reduce the physiological and psychological trauma stress of surgical patients, increase the patient's comfort after surgery, and accelerate the patient's recovery process.
