FAQ

What are the commonly used endoscopes in urological surgery?

Commonly used endoscopes in urological surgery include the following:

Uretero-nephroscope: used for the examination and treatment of ureters and kidneys, with a small outer diameter, can flexibly enter the human body for operation.

Urethra-cystoscope: This endoscope is often used to diagnose and treat bladder, urethra and certain upper urinary tract diseases. It enters the bladder through the urethra, can directly observe the situation in the bladder, and can further understand the situation of the kidneys and ureters through intubation.

Prostate resectoscope: mainly used for prostate resection surgery, with ultra-wide angle and large field of view, suitable for prostate plasma resection surgery.

Children's resectoscope: an endoscope designed specifically for children, the size of the instrument is adjusted according to the individual child to achieve non-invasive examination.

Laparoscope: Although not an endoscope in the traditional sense, laparoscopes are also widely used in urology, especially in minimally invasive surgeries such as nephrectomy, pyelostomy, uretero-ureterostomy, prostatectomy and cystectomy.

Fiber ureterorenoscope: This endoscope can be directly connected to the camera and light source system and is suitable for complex ureteral and kidney surgeries.

Flexible fiber endoscope: It has high flexibility, which enables it to examine the renal pelvic cavity system and most of the lower part of the ureter, although there are disadvantages such as small irrigation channel diameter and reduced visibility.

These endoscopes play an important role in urological surgery, not only improving the precision and safety of the surgery, but also greatly reducing the trauma and recovery time of the patient.

What are the specific applications and advantages of ureterorenoscope in urological surgery?

The specific applications and advantages of ureteronephroscope in urological surgery are as follows:

Specific applications
Ureterorenoscope is inserted into the ureter and renal pelvis through the urethra and bladder for examination and treatment. It can visually observe the anatomical structure of the upper urinary tract and diagnose and treat diseases. This technology can be used in pediatric urology and the treatment of adult stones.

Ureterorenoscope is a minimally invasive surgical tool that can be operated without laparotomy, so it has little trauma and short recovery time. For example, Shuotong mirror has shown significant clinical effects in the treatment of upper urinary tract stone obstructive pyonephropathy, with a high stone clearance rate and safety and reliability.

Ulterorenoscope is not only suitable for basic ureteronephroscope examination, but can also be used in combination with advanced technologies such as laser lithotripsy to further improve the treatment effect.

Advantages
As a minimally invasive surgical tool, ureteronephroscope has less trauma to the body, fast postoperative recovery, and less pain for patients.

Minimally invasive surgery is safer, and compared with traditional open surgery, the probability of complications such as postoperative bleeding and infection is lower.

Directly entering the ureter to act on the stone site helps to improve the stone clearance rate.

Ureterorenoscope can be used for the treatment of stones in the upper, middle and lower ureter, and has a wide range of applications.

With the development of technology, fiber ureterorenoscope has the characteristics of high-resolution images, anti-traumatic head design and high temperature and high pressure sterilization, making it safer and more effective in clinical applications.

Different types of ureterorenoscopes vary in price and performance. For example, HAWK mirror has a good application prospect due to its good cost performance.

Ureterorenoscope is widely used in urological surgery. Its main advantages are small trauma, fast recovery, reduced complications, improved stone clearance rate and wide application range.

What are the latest technological advances in the use of urethrocystoscopes in diagnosis and treatment?

The latest technological advances in urethrocystoscopy in diagnosis and treatment are mainly concentrated in the following aspects:

Narrow Band Imaging (NBI): NBI is a new imaging technology that uses the basis of sequential imaging of red, green and blue in white light, and uses special filters to filter white light, removing the red light with the longest wavelength, leaving only blue light with a wavelength of 415 nm and green light with a wavelength of 540 nm. Compared with fluorescent cystoscopy, NBI does not require the photosensitizer to be injected into the bladder in advance, is not limited by photobleaching on the diagnosis time, and is relatively simple to operate and easy to popularize.

Artificial Intelligence (AI): AI can become an important tool for doctors to perform cystoscopy. Cystoscopy datasets for deep learning have identified a sufficient number of rich datasets, including images of multiple tumor types. In addition to detecting bladder tumors, AI can also assist in the diagnosis of interstitial cystitis. Although real-world clinical applications have lagged behind, technological development is progressing.

Flexible cystoscope: Flexible cystoscope can observe the location, degree and length of urethral stricture under direct vision, and can place a suitable catheter for patients with pelvic fractures and acute urethral injury or rupture by inserting a guidewire. In addition, flexible cystoscope can also be combined with laser technology to perform tumor vaporization treatment for patients who are unable to undergo or are unwilling to undergo radical primary urethral tumor surgery.

High-resolution video cystoscope: The digital video cystoscope launched by KARL STORZ is equipped with CMOS chip technology, providing high-quality images, suitable for interdisciplinary and mobile patient treatment. In addition, there are video urethroscopes with high-resolution CCD chip technology, combined with the IMAGE1 S™ camera platform, which sets a new standard for diagnosis and follow-up care.

Optical coherence tomography cystoscope: This is an emerging technology used to improve the correct diagnosis rate of bladder cancer and guide treatment.

Virtual cystoscopy: This is a computer-based cystoscopic examination method that can provide more detailed images of bladder structure, which helps to diagnose and treat bladder diseases more accurately.

What are the significant improvements and effects of prostate resection compared with traditional surgery?

Compared with traditional surgery, prostate resectoscope has significant improvements and effects, which are mainly reflected in the following aspects:

Reduced complications: Bipolar plasma resectoscope adds a median electrode to the working electrode, so that the high-frequency current passes through the medium (normal saline) to generate a loop with the working electrode, thereby avoiding the need for monopolar resection to stick a negative plate and use insulating flushing fluid. This greatly reduces the incidence of transurethral resection of the prostate syndrome.

Reduced risk of nerve stimulation and pacemaker failure: Bipolar technology avoids the transmission of energy through the body, reducing the risk of nerve stimulation and eventual failure of the pacemaker.

Reduced bleeding and coagulation requirements: Bipolar devices incorporate both the active and return electrodes into the electrode, or into the electrode and the resectoscope, reducing heavy bleeding, thereby reducing the need for frequent coagulation and shortening the entire operation time.

Reduced tissue damage: Bipolar devices produce less collateral thermal damage, less tissue charring, and much shorter tissue penetration time, about 50-100 μm.

Shortened operation time: The improved new resectoscope combined with holmium laser for the treatment of benign prostatic hyperplasia and bladder stones is easy to operate and shortens the operation time.

Reduce surgical risks: After the advent of the reflux resectoscope, the flushing fluid can flow back from the inner and outer sheaths of the resectoscope, eliminating the damage of bladder fistula, but also increasing the risk of urethral injury.

Improve surgical efficiency: A comparative study between transurethral plasma resection (TUPKP) and 1470nm laser prostatectomy (LEP) showed that the operation time, intraoperative bleeding, postoperative bladder continuous flushing time and catheter retention time of the TUPKP group were lower than those of the LEP group, and the intraoperative resected prostate weight was significantly higher than that of the LEP group.

Compared with traditional surgery, prostate resectoscope has significant improvements and improved effects in reducing complications, reducing the risk of nerve stimulation and pacemaker failure, reducing bleeding and coagulation requirements, reducing tissue damage, shortening operation time, and improving operation efficiency.

What are the design features of pediatric resectoscopes and their application in pediatric urological surgery?

The design features of pediatric resectoscopes and their application in pediatric urological surgery are as follows:

Design features
High definition: Pediatric resectoscopes are usually equipped with high-resolution camera systems, which can provide clear and delicate surgical fields and help doctors accurately identify diseased tissues.

Flexible operation: The design focuses on operational flexibility, which is convenient for doctors to perform delicate operations in narrow urethra.

Humanized design: The handle and controller may be ergonomically designed to improve the doctor's operating comfort and reduce fatigue caused by long-term surgery.

Functional features:

Electrocutting function: High-frequency current is used for tissue cutting, which has the advantages of fast cutting speed, less bleeding, and fast recovery.
Irrigation system: Equipped with an irrigation system to keep the surgical field clear and help flush out the debris and tissue produced by cutting.
Illumination system: Built-in high-brightness lighting system to ensure sufficient illumination of the surgical field.
Safety and reliability: The resectoscope has multiple safety protection measures, such as the need to select the working mode, working voltage, and limit the current intensity before starting the operation; at the same time, the resectoscope will automatically detect the working status and automatically shut down once a problem is found.

Application
Minimally invasive treatment of pediatric urological diseases: Due to the special physiological structure of children, many advanced treatment equipment is helpless in the treatment of pediatric diseases. However, in the Urology Department of the Third Affiliated Hospital of Zhengzhou University, the newly introduced pediatric cystoscope, pediatric resectoscope and pediatric ureteroscope provide strong support for minimally invasive treatment of pediatric urological diseases.

Specific application cases:

In the Urology Department of the Third Affiliated Hospital of Zhengzhou University, a 3-year-old boy was cured of hydronephrosis using a pediatric resectoscope.

Studies on endoscopic resection of posterior urethral valves in children have shown that endoscopic resection of posterior urethral valves in children is safe and effective if the appropriate endoscope, electrode and resection site are selected.

Clinical effect: According to Young classification, the operation process was smooth, and the postoperative urination patency, urine white blood cells, urine occult blood, blood creatinine level, degree of hydronephrosis and degree of vesicoureteral reflux were significantly improved compared with those before the operation.

Application scope and effect evaluation of laparoscopy in minimally invasive surgery in urology.
The application range of laparoscopic technology in minimally invasive surgery in urology is very wide, covering almost all internal organ surgeries. Specifically, laparoscopic technology is suitable for surgery on organs such as the adrenal glands, kidneys, ureters, bladders, and prostates, including particularly large renal cancers, tumor thrombi in the renal veins and vena cava, etc. In addition, single-port laparoscopic technology has also been successfully used in radical surgery for renal cancer, renal pelvic cancer, ureteral cancer, bladder cancer, and prostate cancer, as well as various types of corrective or reconstructive surgery.

In terms of effect evaluation, laparoscopic surgery has significant advantages. First, laparoscopic surgery has less trauma, less bleeding, faster recovery, and fewer postoperative complications. For example, in one study, 96 patients underwent laparoscopic surgery without blood transfusion and organ damage, and no gas embolism problems. Secondly, laparoscopic surgery has a short recovery time, significantly reduced pain in patients, and faster recovery. In another study, the patient satisfaction rate of the observation group treated with laparoscopic surgery was 95.65%, which was significantly higher than that of the control group of traditional open surgery.
