Shockwave Lithotripsy for Ureter Stones: What You Need to Know
"A closer look at the transgluteal approach and its impact on treating distal ureter stones effectively."
Shockwave lithotripsy is a common treatment for kidney and ureter stones, using high-energy sound waves to break stones into smaller pieces that can be passed more easily. The approach to deliver these shockwaves can vary, and one such method is the transgluteal approach, where the shockwaves are delivered through the gluteal muscles.
A study published in the World Journal of Urology explored the effectiveness of the transgluteal approach for treating distal ureter stones. Distal ureter stones are located in the lower portion of the ureter, near the bladder, and can cause significant pain and discomfort. The study aimed to evaluate if this approach was a viable option for patients.
Recently, an author correction was issued for this study to address an inaccuracy in the funding number. While this correction doesn't change the study's findings, it's an important detail for transparency and accuracy in research. This article will delve into the study's original findings, the correction, and what the transgluteal approach to shockwave lithotripsy means for treating distal ureter stones.
Study Scope and Stone Prevalence
A 2023 article reports that kidney stones affect roughly 10% of Americans and notes that the American Urological Association recommends either shock wave lithotripsy (SWL) or ureteroscopy for surgical management of renal and ureteral stones under 20 mm, with selection influenced by stone size and location. The studies listed here examine SWL outcomes in specific patient groups: one evaluates upper versus lower ureteral stones and the likelihood of being stone-free after one session, while another followed 119 patients with renal and upper ureteric stones treated at a university-affiliated tertiary hospital over 12 months. A separate study describes evaluating stone-free rates in 190 patients with upper ureteral calculi. These study descriptions establish the populations and questions examined, but the supplied information does not report their outcome rates.
Treatment Options and Evidence Limits
For urinary stones smaller than 20 mm, shockwave lithotripsy treats the stone with shockwaves applied through the skin, without surgery, according to the International Alliance of Urolithiasis guideline. Ureteroscopic treatment instead uses a small semi-rigid or flexible scope to visualize and fragment stones with devices such as a holmium laser; smaller lower-ureter stones may sometimes be removed intact with a basket. A review of renal-stone treatment found that a limited number of randomized trials and observational studies suggest ureteroscopy may achieve higher stone-free rates than SWL, but the reports were weakened by small samples and limited control for confounding. The supplied guideline excerpt describes SWL as an approach for stones under 20 mm but does not provide a direct comparison of outcomes for ureteral stones.
Understanding the Transgluteal Approach in Shockwave Lithotripsy
The transgluteal approach involves delivering shockwaves through the gluteal muscles to target stones in the distal ureter. This method has potential benefits, but also requires careful consideration of patient anatomy and potential risks.
- Effectiveness: The study likely provided data on the stone-free rate, meaning the percentage of patients who were completely cleared of stones after the procedure.
- Safety: The research would have examined potential complications such as pain, bleeding, or damage to surrounding tissues.
- Patient Selection: The study may have identified specific characteristics of patients who are most likely to benefit from this approach.
New Strategies and Evidence Reviews
A 2024 review describes SWL as an important treatment for urinary tract stones and discusses new concepts and procedural strategies intended to improve results and clinical practice. Another review, published in 2025, is a systematic review and meta-analysis of the clinical effectiveness of SWL, retrograde intrarenal surgery, and percutaneous nephrolithotomy for lower-pole renal stones. A separate 2024 review identifies burst wave lithotripsy and ultrasonic propulsion as emerging noninvasive technologies that may fragment or reposition kidney stones, separately or together. The supplied descriptions do not provide comparative effect estimates or establish these emerging technologies as routine care.
Source Does Not Address Stone Treatment
The sole supplied source for this subsection concerns cracked teeth with endodontitis or periapical disease, not ureter stones or lithotripsy. It describes randomizing patients to one-visit or several-visit root canal treatment and comparing clinical responses and effects. It therefore does not provide evidence for comparing shockwave lithotripsy with ureteroscopy or other stone treatments. No stone-treatment comparison can be drawn from this source.
The Future of Stone Treatment
The transgluteal approach to shockwave lithotripsy represents an option in the treatment of distal ureter stones. As research continues, healthcare providers will refine their techniques and criteria for patient selection, potentially leading to even better outcomes.
Practice Trends and Emerging Tools
A 2026 international study description says that SWL use has declined as endourological techniques have expanded, although SWL remains widely available; it also notes limited contemporary international data on utilization, technical delivery, operator models, outcome assessment, and AI-based tools. A 2025 clinical review likewise reports a decline in SWL use among US-based practitioners and places the treatment’s commercial introduction in the 1980s. Separately, a market report projects demand to grow at a 5.8% compound annual growth rate from 2026 to 2036, from USD 1.6 billion in 2026 to USD 2.8 billion by 2036. These sources describe different measures—clinical use and market demand—so the market projection does not resolve the reported decline in use.
Patient Outcomes, Procedures, and Costs
A large trial comparing ureteroscopy with extracorporeal SWL for ureteric stones reported marginally better stone clearance with ureteroscopy and better healthcare-cost results with SWL. A separate overview says both interventions are effective but differ in invasiveness, anesthesia requirements, treatment setting, number of procedures, complications, patient-reported outcomes, and cost. A New York State analysis used the SPARCS database to study treatment failure and perioperative complications among patients undergoing ureteroscopy or SWL, but the supplied description does not give its results. The overview and trial address patient-relevant tradeoffs, while the database study description identifies outcomes investigated rather than findings.
If you're experiencing symptoms of kidney or ureter stones, such as severe pain, blood in your urine, or frequent urination, it's important to consult a healthcare professional. They can properly diagnose your condition and recommend the most appropriate treatment plan for your specific needs.
