Not long ago, professor Petrisor Geavlete, a fellow of the Romanian Academy of Medical Sciences, vice president of the Romanian Urology Association, Professor of "Carol Davila" University of Medicine and Pharmacy, and reviewer for European Urology (2009), shared his experience with PU3022A on the official website of Romania's largest private hospital (SANADOR Clinical Hospital).

Professor Petrisor Geavlete highly praised the bending performance, image quality and stone clearance rate of PU3022A.

Kidney stones are common in Romania and urinary stones, especially kidney stones, can occur at any age and Kidney stones should be diagnosed and treated as soon as possible. Any postponement or delay of the intervention can lead to irreversible repercussions on the kidney, Professor Petrisor Geavlete noted.
Flexible ureteroscopy has the advantages of short hospital stay (1-2 days) and quick recovery. And disposable flexible ureteroscope also has many advantages such as safer operation, immediate application, no need for disinfection, no pollution, and no maintenance. Therefor, professor Petrisor Geavlete strongly recommends the use of a disposable flexible ureteroscope to treat stones.

The clinical advantages of PU3022A in treating kidney stones are vivid and graphic by Professor Petrisor Geavlete.
The bending performance of PU3022A is significantly better than that of reusable digital ureterosocope with international influence.
PU3022A has superior image quality, and both the image of fragmentation and transformation into sand of a kidney stone of about 2.6 cm(left) and the transformation into sand of a 1.9 cm kidney stone located at the level of the lower calyx(right) is extremely clear.

No significant remaining lithiasis after PU3022A.
In fact, the advantages of PU3022A are far more than those mentioned above.
PU3022A is the first disposable flexible ureteroscope approved by the US FDA in China.

At the same time, evidence-based medicine shows that PU3022/PU3022A is safe and effective.

And global training centers, international certificates, 10 more patents, and being sold in more than 100 countries and regions are all due to the excellent performance and superior quality of PU3022A.

PUSEN Medical partners with leading clinicians, researchers, and scientists worldwide to continually advance the quality of patient care with innovative medical technology for the interventional and surgical treatment of urolithiasis, ear-nose-throat and respiratory diseases.

Endoscopic treatment of renal lithiasis with 

single-use full-HD ureteroscope
Kidney stones are very common in Romania. Unfortunately, urinary stones, especially kidney stones, can be diagnosed at any age and, happily, treatment methods have changed dramatically in recent years.
Endoscopy Treatment for Kidney Stone
Endoscopy, minimally invasive, is one of the most effective methods for kidney stones. Flexible ureteroscopy is a surgical technique by which the renal pelvis and calyces (the whole kidney) can be observed with the help of a high-performance flexible ureteroscope. Therefore, urologists can treat any stones (kidney stones) with the help of a flexible ureteroscope.
SANADOR Clinical Hospital has high-performance technology for the endoscopic treatment (without scalpel) of kidney stones. The instruments used for this type of intervention, flexible ureteroscopes, are constantly being replaced with more efficientones and are continuously improving their the rapeutic efficiency. 
Professor Petrișor Geavlete obtained the first results in Romania through flexible ureteroscopy, currently having one of the most significant experiences worldwide - over 5,000 such procedures.


Disposable ureteroscopes

About 2 years ago, the first clinically significant evaluations of the use of single-use ureteroscopes appeared worldwide.


Images of the pielo-caliceal system (inside the kidney) displayed on Sony's 55-inch 4K-resolution medical monitor, equipped with the SANADOR Clinical Hospital.




Intraoperative appearance with 2 medical monitors in series (one PUSEN and one 55-inch Sony with 4K resolution). The kidney stone and the laser fiber in its vicinity are very clearly.





At SANADOR Clinical Hospital, the full-HD version of the flexible disposable ureteroscope is available.

For each patient, there should be a flexible ureteroscope. The advantages for the patient are major: new instrument for each patient with kidney stones, safer procedure, no sterilization required (the device is already sterile in the factory), no contamination, the possibility to use this technology immediately and at anytime, no repairs, etc.
About 2 years ago, Prof. Dr. Petrisor Geavlete presented the first evaluations with this type of minimally invasive technique nationally and internationally. To date, there are already more than 200 cases operated with this method, the experience gained being a European benchmark. In particular, PUSEN technology was used: PU3022A digital flexible ureteroscope (PUSEN, Zhuhai China), with very good results. The stone-free treatment for stones below 2cm, with any localization in the kidneys, is over 95%.

Intraoperative appearance with two medical monitors in series (one PUSEN and one 55-inch Sony, with 4K resolution). The aspect of fragmentation and transformation into sand of a kidney stone of about 2.6 cm is objectified with exceptional clarity.

Flexible ureteroscopy at SANADOR Clinical Hospital 
If studies compared to conventional instruments (reusable ureteros) demonstrated similar technical characteristics (maximum deflation with or without laser fiber), with a slight advantage of single-use ureteroscopes, the full-HD novelty of image quality brought a special feature. For the patient it is safer when what the surgeon sees and treats is better visualized.

For patients with kidney stones, the minimally invasive option (flexible ureteroscopy) is currently offered by centers of excellence. At SANADOR Clinical Hospital, the patient with such a condition and with clear the rapeutic indications (according to the European Guide of Urology) has the possibility to be treated very modern and effective, with the help of the latest technology.
Thus, there are no kidney stones that can not be sprayed with the laser. The scalpelis "disbanded" (interventions without incisions), and entry directly into the kidneys (percutaneous nephrolitomy) with another type of apparatus isavoided. Superior efficiency is evident in all comparative studies between flexible ureteroscopy and ESWL (extracorporeal shock wave litotrition). And not to mention the classic scalpel operation, which, in many countries, has rare indications.
It is important to note that all intranal localizations of renal stones can be addressed with flexible ureteroscope. The admission is short -term (1 – 2days), and recovery is very quick.
Kidney stones should be diagnosed and treated as soon as possible. Any postponement ordelay of the intervention can lead to irreversible repercussions on the kidney. For stone sizes up to 2.5 cm, completely endoscopic, minimally invasive treatment is possible, using modern technology from SANADOR Clinical Hospital.
