Patient's question:
Last week, I was taken to the hospital due to severe abdominal pain. The doctor examined me and said I had ureteral stones. They performed a procedure to break up the stones and said that as long as the stones were passed out, everything would be fine. However, during this process, I was also given progesterone. Why did I need to receive progesterone?Doctor's answer:
Hello:Ureteral calculus, the use of progesterone is to dilate the ureteral smooth muscle, assisting in the expulsion of the calculus. It is recommended to first choose extracorporeal shock wave lithotripsy (ESWL) for calculus treatment. Early treatment is advised for better outcomes.
First, let me explain that ESWL is a non-invasive, advanced treatment device and technology for calculus removal. Its principle is entirely different from that of extracorporeal shock wave lithotripsy (ESWL). The advantage of ESWL lies in its lack of organ damage, thorough calculus removal, minimal patient discomfort, and easy acceptance. In contrast, extracorporeal shock wave lithotripsy (ESWL) causes organ damage and is more painful.
The ESWL technology employs high-frequency superconducting fluid dynamic shock wave dynamics in a three-dimensional integrated system, assisted by large digital ultrasound for precise positioning. It features accurate targeting, rapid calculus removal, and is particularly effective for biliary calculus, ureteral calculus, allowing calculus to move out as it is dislodged. It is especially effective for intrahepatic calculi with.
The most prominent feature of this equipment is its user-friendly operability, thorough calculus removal for various types, broad applicability, minimal side effects on the human body, painless treatment, no need for hospitalization, and low treatment costs, making it highly acceptable to patients. It is a reliable, effective, simple, and practical treatment device with unique equipment and technical advantages. Therefore, it is currently the best choice for treating various calculi.
ESWL is the optimal choice for renal calculi and ureteral calculi under 10mm. Generally, after several treatments, the calculus can be expelled. For larger calculi, the principle of first crushing and then dislodging can be adopted to achieve complementary advantages. However, for ureteral calculi, treatment must be delayed by 3-5 days after the calculus and local ureteral congestion and edema subside before dislodging.
Generally, calculus removal is relatively easy. With the widespread use of ultrasound, the diagnosis of ureteral calculi is timely and easy. Small calculi entering the ureter are usually detected early, providing the best conditions and timing for ESWL treatment. For calculi lodged in the ureter for a long time, removal is difficult and may require surgery or ureteroscopy.
At the same time, it is crucial to provide patients with the latest measures for early calculus removal, avoiding excessive treatment methods that cause significant organ damage, poor outcomes, pain, prolonged time, and high costs.
The indications and scope of treatment for ESWL are as follows:
(1) For renal and ureteral calculi smaller than 1.2cm, ESWL should be the first choice for calculus removal due to its lack of kidney damage, thorough removal, safety, and painlessness, without the side effects of shock wave lithotripsy. If the calculus diameter exceeds 1.2cm, extracorporeal shock wave lithotripsy (ESWL) should be used first to crush the calculus, followed by ESWL for thorough removal, achieving complementary advantages.
(2) This equipment is particularly suitable for acute ureteral calculi and the resulting hydronephrosis, renal pelvis dilation, ureteral hydronephrosis, ureteral dilation, and renal colic. It can rapidly expel ureteral calculi, immediately relieve pain, and quickly alleviate symptoms, making it the preferred treatment for ureteral calculi.
(3) For patients with multiple renal calculi on the same side combined with ureteral calculi, the ureteral calculus should be removed first, followed by the removal of multiple renal calculi, to prevent the formation of a "stone street" in the ureter.
(4) For large renal calculi, after ESWL fragmentation, small residual calculi in the lower pole of the kidney and renal pelvis are the best indications for ESWL for thorough calculus removal. This is because the handheld high-frequency superconducting shock wave transducer can directly touch the calculus in the lower pole of the kidney, moving it into the renal pelvis and ureter for expulsion.
(5) For calculus removal in the above-mentioned cases, if urinary tract infection leads to pyelonephritis, ureteritis, cystitis, prostatitis, or urethritis, due to inflammatory congestion and swelling of the mucosa affecting calculus removal, antibiotic treatment must be administered first to resolve inflammation before ESWL treatment.
(6) Generally, 1-3 ESWL treatments are sufficient to completely remove the calculus, with a duration of 5-7 days. Patients in good physical condition can undergo continuous treatments, while those with poorer health may receive treatment every other day. If there are urinary dysfunction or infections, hospitalization may be prolonged. According to clinical observations, Professor Chen Bangjing believes that ESWL is a leading new technology for treating calculi domestically and internationally, being the preferred method for renal, ureteral (which are usually expelled within two hours), gallbladder, and extrahepatic bile duct calculi. Its completely thorough calculus removal, lack of organ damage, and low cost have benefited a vast number of patients.
For calculi beyond the scope of ESWL, extracorporeal shock wave lithotripsy (ESWL) should be performed first, followed by calculus removal. For large renal cast calculi and gallstones, surgical removal is recommended upon discovery.
