一位30歲的張先生半夜右腰及右下腹劇烈疼痛且全身冒冷汗,伴隨噁心嘔吐、頻尿及肉眼可見性血尿。經診斷後,在右側輸尿管上端卡了一顆由腎臟掉下來的1cm結石。經手術處理後順利清除輸尿管結石。不幸的是張先生右邊腎臟還有兩顆1.5cm的腎結石,成了不定時炸彈,讓張先生困擾不已,害怕石頭再次掉入輸尿管造成劇烈疼痛。

常見卻難以處理的腎結石

現今社會由於不良飲食習慣與基因、體質的關係,泌尿道結石越來越多,其中又以腎結石為最常見也最難處理。

傳統腎結石的處理方式包含體外震波碎石手術、硬式輸尿管鏡碎石手術、腎臟造廔內視鏡碎石手術等,但腎臟是個構造錯綜複雜的器官,可以藏匿各種大小的結石,再加上傳統器械角度及粉碎力道都有其極限,常無法處理較困難的腎結石。

終結腎結石:零死角軟式輸尿管鏡

有別於一般傳統的器械,現今泌尿科已發展出治療腎結石的終極武器——零死角軟式輸尿管鏡。

它一般分為電子式及光學式兩種。電子式比光學式有更清晰完整的視野,讓醫生在擊發粉碎結石上更為精準。零死角軟式輸尿管鏡內含非常精密的設計,可隨意轉彎高達270度,配合高解析度的電子式鏡頭及搭配直徑200微米的極細超高能量鈥雷射,經由尿道在無任何傷口的情況下,能夠瞬間把結石擊成粉碎,零死角的處理各種傳統方法無法觸及的腎結石,大大提高腎結石的清除率。

因為無傷口,不用開刀,所以術後復原很快且幾乎無疼痛感,住院2天即可出院。它除了治療結石,也可用來診斷及處理輸尿管彎曲狹窄、輸尿管癌及腎盂癌等多種泌尿科疾病。

零死角軟式輸尿管鏡在國外已發展多年,逐漸成為治療泌尿道結石的趨勢及第一線選擇之一。目前已發展到最新的電子式軟式輸尿管鏡搭配60瓦超高能量鈥雷射,未來更會引進拋棄式軟式輸尿管鏡,為一般腎結石、傳統方法無法處理的困難腎結石及泌尿道癌的診斷治療,提供了最好的選擇。

A 30-year-old Mr. Zhang had severe pain in his right waist and right lower abdomen in the middle of the night, and his body was cold and sweaty, accompanied by nausea and vomiting, frequent urination and visible hematuria. After diagnosis, a 1cm stone that fell from the kidney was stuck at the upper end of the right ureter. The ureteral stones were successfully removed after surgical treatment. Unfortunately, Mr. Zhang’s right kidney has two 1.5cm kidney stones, which became an untimely bomb, which made Mr. Zhang troubled. He was afraid that the stone would fall into the ureter again and cause severe pain.

Common but difficult to handle kidney stones

In today's society, due to the relationship between bad eating habits and genes and physique, there are more and more urinary calculi, and kidney stones are the most common and difficult to handle.

Traditional kidney stones are treated by extracorporeal shock wave lithotripsy, rigid ureteroscopic lithotripsy, and renal ostomy endoscopic lithotripsy. However, the kidney is a complex organ that can hide stones of various sizes, plus tradition. Instrument angles and comminution forces have their limits and often cannot handle difficult kidney stones.

End of kidney stones: zero dead angle soft ureteroscope

Different from the traditional equipment, the urology department has developed the ultimate weapon for the treatment of kidney stones - zero dead angle soft ureteroscope.

It is generally divided into electronic and optical. The electronic style has a clearer and more complete view than the optical one, allowing the doctor to be more precise in firing the crushed stones. The zero dead angle soft ureteroscope contains a very precise design that can be turned freely up to 270 degrees, with a high-resolution electronic lens and a very fine ultra-high energy 鈥 laser with a diameter of 200 microns, through the urethra without any wounds. It can instantly crush the stones into smashes, and deal with kidney stones that cannot be touched by various traditional methods at zero dead angles, greatly improving the clearance rate of kidney stones.

Because there is no wound, there is no need to open the knife, so the postoperative recovery is very fast and almost no pain, and can be discharged after 2 days in hospital. In addition to treating stones, it can also be used to diagnose and treat various urological diseases such as ureteral stricture, ureteral cancer and renal pelvic cancer.

Zero dead angle soft ureteroscopy has been developed abroad for many years and has gradually become one of the first trends in the treatment of urinary calculi. At present, the latest electronic soft ureteroscope with 60 watt ultra-high energy 鈥 laser has been developed. In the future, a disposable soft ureteroscope will be introduced, which is a diagnosis of difficult kidney stones and urinary tract cancer which cannot be treated by general kidney stones and traditional methods. Treatment offers the best choice.
