Patient's question:
What should I do if there is a stone at the ureteral transition? 12mm-9mmDoctor's answer:
Hello: Ureteral stones measuring 12mm-9mm can be easily diagnosed through clinical ultrasound. Generally, kidney stones that fall into the ureter are diagnosed as ureteral stones. They often cause ureteral obstruction, leading to renal pelvis dilation and hydronephrosis. If ureteral stones causing obstruction are not promptly removed, it may result in kidney damage and failure. In the early stages, it often presents with lower back pain and discomfort, severe renal colic, causing great suffering to the patient. Lower and middle ureteral stones can reflect pain in the penis, testicles, and perineum. Accompanied by symptoms such as nausea and vomiting. The recommended first choice for stone removal treatment is the non-invasive extracorporeal shock wave lithotripsy (ESWL) machine - [Registration No. = Henan Food and Drug Administration (Approval) 2012 No. 2260216)]. Early treatment is highly effective, with stones typically passing within 1-3 hours, requiring no hospitalization, and allowing patients to leave immediately.First, it should be noted that the extracorporeal shock wave lithotripsy machine is a new non-invasive stone removal treatment device and technology. Its principle is entirely different from that of extracorporeal shock wave lithotripsy. The advantage of extracorporeal shock wave lithotripsy lies in its lack of organ damage, thorough stone removal, minimal pain for patients, and easy acceptance. In contrast, extracorporeal shock wave lithotripsy can cause organ damage and is more painful.
The extracorporeal shock wave lithotripsy technology employs high-frequency superconducting fluid dynamic shock wave three-dimensional integrated stone removal technology, assisted by large digital ultrasound for precise positioning. It features accurate positioning, rapid stone removal, and is particularly effective for biliary stones, ureteral stones, allowing immediate discharge after treatment. It is especially effective for resolving in the intrahepatic bile ducts. The most prominent feature of this equipment is its user-friendly operability, thorough stone removal for various types, broad applicability, minimal side effects on the human body, painless treatment process, generally no need for hospitalization, and low treatment costs, making it easily accepted by patients. It is a reliable, effective, simple, and practical treatment device with unique equipment and technological advantages. Therefore, it is currently the best choice for treating various types of stones.
The non-invasive extracorporeal shock wave lithotripsy machine is the optimal choice for kidney and ureteral stones under 10mm. Generally, after several treatments, stones can be completely removed. For larger stones, the principle of first crushing and then removing the stones can be adopted to achieve complementary advantages. However, for ureteral stones, it is necessary to wait for 3-5 days after the local ureter becomes congested and edematous before performing stone removal treatment. Generally, stones are relatively easy to remove.
Whether it is small ureteral stones or larger multiple stones, due to the widespread use of ultrasound, the diagnosis of ureteral stones is now more timely and easier. Small stones entering the ureter are usually detected early, providing the best conditions and timing for extracorporeal shock wave lithotripsy treatment. For stones that have been lodged in the ureter for a long time, it is difficult to remove them and may require surgical or ureteroscopy procedures. At the same time, it is also important to provide patients with the latest measures for early stone removal treatment, avoiding excessive and harmful treatment methods that cause significant organ damage, poor efficacy, pain, and high costs.
The indications and scope of treatment for the non-invasive extracorporeal shock wave lithotripsy machine are as follows:
(1) For various kidney and ureteral stones less than 1.2cm in diameter, extracorporeal shock wave lithotripsy should be the first choice for stone removal treatment. This method causes no kidney damage, ensures thorough stone removal, is safe and painless, and avoids the side effects of shock wave lithotripsy. If the stone diameter exceeds 1.2cm, extracorporeal shock wave lithotripsy should first be used for crushing, followed by extracorporeal shock wave lithotripsy for thorough stone removal, achieving complementary advantages.
(2) This equipment is particularly suitable for acute ureteral stones and the resulting renal pelvis dilation, hydronephrosis, ureteral obstruction, ureteral dilation, and renal colic. It can quickly remove ureteral stones, alleviate pain immediately, and rapidly relieve symptoms, making it the preferred treatment for ureteral stones.
(3) For patients with multiple kidney stones on the same side combined with ureteral stones, the ureteral stones should be removed first, followed by the removal of multiple kidney stones, to prevent the formation of a "stone street" in the ureter.
(4) For large kidney stones that remain in the lower pole of the kidney, renal pelvis, or calyces after ESWL, these small stones are the optimal indication for extracorporeal shock wave lithotripsy. This is because the handheld high-frequency superconducting shock wave probe can directly touch the stones in the lower pole of the kidney, moving them into the renal pelvis and ureter for removal.
(5) For the treatment of various types of stones mentioned above, if complications such as urinary tract infections lead to pyelonephritis, ureteritis, cystitis, prostatitis, or urethritis, and if inflammatory congestion and swelling of the mucosa affect stone removal, antibiotic anti-inflammatory treatment must be administered first. Stone removal treatment should only be performed after inflammation subsides.
(6) Extracorporeal shock wave lithotripsy treatment generally requires 1-3 sessions to completely remove stones, with a duration of 5-7 days. Patients in good physical condition can undergo continuous treatment, while those with poorer health may need to be treated once every other day. If patients have poor urinary function or infections, the hospitalization period may be longer.
According to clinical observations, Professor Chen Bangjing believes that extracorporeal shock wave lithotripsy is the leading new technology for treating stones both domestically and internationally. It is the preferred method for treating kidney stones, ureteral stones (which generally pass within two hours), gallstones, and extrahepatic bile duct stones. Its completely thorough stone removal effect, lack of organ damage, and low cost have benefited a vast number of patients. For stones beyond the scope of extracorporeal shock wave lithotripsy, extracorporeal shock wave lithotripsy should first be used for crushing, followed by stone removal. For large kidney cast stones and gallstones, surgical removal is recommended upon discovery.
