Efficacy of Extracorporeal Shock Wave Lithotripsy (ESWL) versus Pneumatic Ureteroscopic Lithotripsy (URSL) for Lower Ureteral Stones Therapy in Asia: A Meta-Analysis

Objective: To assess the efficacy and safety of extracorporeal shock wave lithotripsy or pneumatic ureteroscopic lithotripsy for lower ureteral stones therapy, we sought to identify and summarize randomized controlled trials that were used to treat distal ureteral stone. Methods: Eligible studies were identified from electronic databases. Database search, quality assessment, and data extraction were performed by two reviewers independently. Our primary outcome was the stone-free rate. Secondary outcomes were the fragmentation rate, complications and the rate of re-treatment and secondary procedures. The results were assessed by Review Manager 5.0. Publication bias was evaluated by Stata 11.0. Results: 13 trials were included. Meta-analysis of pooled data showed that pneumatic ureteroscopic lithotripsy demonstrated a significant advantage over extracorporeal shock wave lithotripsy (OR = 0.14, 95% CI [0.09, 0.23], P < 0.00001) in the stone-free rate;the extracorporeal shock wave lithotripsy had statistical disadvantages over pneumatic ureteroscopic lithotripsy in the fragmentation rate of ureteral stones (OR = 0.14, 95% CI [0.05, 0.39], P = 0.0002);and the rate of re-treatment and secondary procedure was lower in pneumatic ureteroscopic lithotripsy than in extracorporeal shock wave lithotripsy (OR = 5.37, 95% CI [2.61, 11.07], P < 0.00001). Our pooled results showed that there was no statistical difference between extracorporeal shock wave lithotripsy and pneumatic ureteroscopic lithotripsy in hematuresis, ureteral stricture and urosepsis or fever. Finally extracorporeal shock wave lithotripsy had a higher incidence of colic pain than pneumatic ureteroscopic lithotripsy. Conclusion: The present meta-analysis suggested that pneumatic ureteroscopic lithotripsy had large advantages over extracorporeal shock wave lithotripsy in the treatment of lower ureteral stones.

Epidural anesthesia is effective for extracorporeal shock wave lithotripsy of pancreatic and biliary calculi

AIM: To evaluate the efficacy of thoracic epidural analgesia for extracorporeal shock wave lithotripsy (ESWL). METHODS: ESWL is an effective, non-invasive technique for the treatment of difficult pancreatic and large bile duct calculi. The procedure is often painful and requires large doses of analgesics. Many different anesthetic techniques have been used. Patients with either large bile duct calculi or pancreatic duct calculi which could not be extracted by routine endoscopic methods were selected. Thoracic epidural anesthesia (TEA) was routinely used in all the subjects unless contraindicated. Bupivacaine 0.25% with or without clonidine was used to block the segments D6 to D12. The dose was calculated depending on the age, height and weight of the patient. It was usually 1-2 mL per segment blocked.RESULTS: Ninety eight percent of the 1509 patients underwent ESWL under TEA. The subjects selected were within American Society of Anesthesiologists grade Ⅰ to Ⅲ. ESWL using EA permitted successful elimination of bile duct or pancreatic calculi with minimal morbidity. The procedure time was shorter in patients with TEA than in those who underwent ESWL under total intravenous anesthesia. CONCLUSION: Almost all patients undergoing ESWL with EA had effective blocks with a single catheter insertion and local anesthetic injection.

Outcome of a session of extracorporeal shock wave lithotripsy before endoscopic retrograde cholangiopancreatography for problematic and large common bile duct stones

AIM To compare the efficacy of a session of extracorporeal shock wave lithotripsy(ESWL) before endoscopic retrograde cholangiopancreatography(ERCP) vs ERCP only for problematic and large common bile duct(CBD) stones.METHODS Adult patients with CBD stones for whom initial ERCP was unsuccessful because of the large size of CBD stones were identified. The patients were randomized into two groups,an "ESWL + ERCP group" and an "ERCP-only" group. For ESWL + ERCP cases,ESWL was performed prior to ERCP. Clearance of the CBD,complications related to the ESWL/ERCP procedure,frequency of mechanical lithotripsy use and duration of the ERCP procedure were evaluated in both groups.RESULTS There was no significant difference in baseline characteristics between the two groups. A session of ESWL before ERCP compared with ERCP only resulted in similar outcomes in terms of successful stone removal within the first treatment session(74.2% vs 71.0%,P = 0.135),but a higher clearance rate within the second treatment session(84.4% vs 51.6%,P = 0.018) and total stone clearance(96.0% vs 86.0%,P = 0.029). Moreover,ESWL prior to ERCP not only reduced ERCP procedure time(43 ± 21 min vs 59 ± 28 min,P = 0.034) and the rate of mechanical lithotripsy use(20% vs 30%,P = 0.025),but also raised the clearance rate of extremely large stones(80.0% vs 40.0%,P = 0.016). Post-ERCP complications were similar for the two groups.CONCLUSION Based on the higher rate of successful stone removal and minimal complications,ESWL prior to ERCP appears to be a safe and effective treatment for the endoscopic removal of problematic and large CBD stones.

Effect of extracorporeal shock wave lithotripsy for the postoperative residual bilestone of choledocholithiasis

Objective To explore the effect of extracorporeal shock wave lithotripsy(ESWL) for the postoperative residual bilestone of choledocholithiasis.Method Inject contrast medium of biligrafin via T tube.After accurate apposition with X ray,take lithotripsy with extracorporeal shock wave. In some cases T tube washing and transcutaneous choledochoscope were used to take out bilestones.Results The lithotripsies were successful in all the 48 patients and the lithotriptic rate was 100%.The removing rate of bilestones was over 90% with washing method.Choledochoscope was used in 6 cases,and 48 patients were completely healed.In them 24 suffered from slight expanding pain in right upper abdomen or nausea and no any complications and sequelae in others.Conclusion ESWL is an effect method to heal patients with the postoperative residual bilestones of choledocholithiasis.

Extracorporeal Shock Wave Lithotripsy in the Treatment of Single Ureteric Stone. Initial Data from Iraq

Background: Extracorporeal shock wave lithotripsy (ESWL) became the first line in the treatment of ureteric stone after failure of conservative treatment because of its safety, simplicity and effectiveness. It is not invasive procedure and can be done on outpatient basis without anesthesia and with few complications which is most probably temporary and treatable. The objective of this study is to evaluate the efficiency and safety of ESWL in treatment of ureteric stone in Iraq. Materials and Methods: A total of 112 Iraqi patients with ureteric stones were participated in this prospective observational study in which patients scheduled for ESWL treatment for a period of 6 months. Patients were divided into 2 groups: 1) Group 1: 52 patients with proximal ureteric stone;2) Group 2: including 60 patients with distal ureteric stone. Preoperatively all patient underwent bowel preparation and were asked to fast for 8 hours before the procedure. Results: The age ranged between 22 and 55 with mean of 42 (SD = 5) years. Around 46% had proximal ureteric stone and the rest were in distal ureter. Around 44% needed one session and 40% needed two sessions to be stone-free respectively. In regards to associated symptoms, 74% had ureteric colic, 3% haematuria, 43% microhematuria and 12% UTI. Mild hydronephrosis was found in 90% of the cases and 30 reported had previous intervention. Success rate was 90%. Conclusions: ESWL is safe and effective in treatment of ureteric stone with few complications and must be regarded first choice after conservative treatment in a patient with uncomplicated ureteric stone.

Changes of serum β2-MG, Cys C and urine mAlb levels in patients with ureteral calculi before and after extracorporeal shock wave lithotripsy and their clinical significance

Objective:To investigate the changes of serumβ2 microglobulin(β2-MG),cystatin C(CysC)and urine microalbumin(mAlb)levels in patients with ureteral calculi before and after extracorporeal shock wave lithotripsy and their clinical significance.Methods Sixty-eight patients with ureteral calculi admitted to the hospital between June 2018 and June 2019 were selected as the observation group.35 volunteers who received physical elimination in the hospital during the same period were selected as the control group.Levels ofβ2-MG,Cys C and urine mAlb in the observation group were compared before and after treatment,and compared with those in the control group.Changes in serumβ2-MG,Cys C and urine mAlb levels and renal function indicators[blood urea nitrogen(BUN),serum creatinine(SCr)]in patients with different prognosis in the observation group after treatment were analyzed.The value of serumβ2-MG,Cys C and urine mAlb levels in the diagnosis and treatment of ureteral calculi was analyzed with ROC curve.The correlations between serumβ2-MG,Cys C and urine mAlb levels and renal function indexes were analyzed.Results Serumβ2-MG,Cys C and urine mAlb levels in the observation group before treatment were significantly higher than those in the same group after treatment or those in the control group(P<0.05).Serumβ2-MG,Cys C and urine mAlb levels,BUN and SCr in patients with residual stones were significantly higher than those in patients without(P<0.05).ROC curve analysis showed that the sensitivity and the area under the curve of combined detection of serumβ2-MG,Cys C and urine mAlb levels for evaluating the curative effect of extracorporeal shock wave lithotripsy on ureteral calculi were significantly higher/larger than those of single detection of the three(P<0.05).Partial correlation analysis showed that serumβ2-MG,Cys C and urine mAlb levels were positively correlated with BUN and SCr(P<0.05).Conclusion There are obvious changes of serumβ2-MG,Cys C and urine mAlb levels in patients with ureteral calculi before and after extracorporeal shock wave lithotripsy.The combined detection of the three indexes is helpful for the early diagnosis of ureteral calculi and the evaluation of renal function after lithotripsy.They can provide reference for protecting renal function in patients with ureteral calculi treated by extracorporeal shock wave lithotripsy.

EXTRACORPOREAL SHOCK WAVE LITHOTRIPSY FOR URINARY CALCULI: 18 YEARS EXPERIENCE

Objective To report our experience of extracorporeal shock wave lithotripsy （ESWL） for patients with urinary calculi. Methods From Jun. 1987 to Dec. 2005, a total of 10100 patients with urinary calculi in the kidney or ureter accepted ESWL. The kidney stones were sorted by FDA standard. The ureteric stone was sorted by its site and retrograde pyelography. At the same time, we summarized the recurrence of kidney stone and its relationship between extracorporeal shock wave lithotripsy （ ESWL ） and hypertension. Results The efficacy for class I kidney stone was 91.2% that for class II 86. 5% and class III 72.3% , the healing rate for ureteric stone was 84. 5%. Combined retrograde pyelography and ESWL couM improve the efficacy. If ESWL failed, the ureteric stone could still be removed by operation or ureterscopy （ 1.1% ）. The rate of recurrence of kidney stone was 6. 1% and the incidence of hypertension post-treatment reached 7. 9%. Conclusion ESWL is a preferred approach to treat urinary calculi.

Indications and contraindications for shock wave lithotripsy and how to improve outcomes

For over 35 years shock wave lithotripsy has proven to be an effective,safe and truly minimally invasive option for the treatment of nephrolithiasis.Various technical factors as well as patient selection can impact the success of the procedure.We used published work focusing on outcomes of shock wave lithotripsy,risk of complications,and strategies for improving stone fragmentation to create this review.Multiple patient and technical factors have been found to impact success of treatment.Skin to stone distance,stone density and composition,size and location of the stone within the urinary system all influence stone free rates.A slower rate with a gradual increasing voltage,precise targeting,proper coupling will improve stone fragmentation and decrease risk of complications.The selection of appropriate patients through a shared decision making process and attention to the technical factors that improve stone free rates is key to providing an effective treatment and patient satisfaction.

The Relationship Between the Energy Levels of Shock Waves and the Degree of Renal Damage After ESWL:A Prospective Clinical Matching Trail

In an attempt to understand the effects of high energy shock wave (HESW)on renal function, we studied prospectively 40 patients with nephrolithiasis in 4 groups,using same voltage with different numbers of shock wave therapy to identify the difference of effects on renal function. Stone burdens and posit ion were similar in these groups. Each group received 1500, 2000, 2500 or 3000 puises at 12. 5 KV on JT-3lithotripotor respectively. All the groups had significantly increased the levels of urinary NAG, β2MG, ALB and serum β2MG, which reached the highest values on 1-3days after ESWL (P<0. 001), and then decreased to the pre-ESWL levels except urinary NAG in group Cand D and serum β2MG which were still significantly higher (P<0.05) than those before-ESWL on the 7th day after ESWL. There was significant correlation between either urinary NAG (γ=0. 977, P<0. 05) or β2MG (γ=0. 933, P<0. 001) with the number of shock wave. In addition, urinary NAG and β2MG increased significantly when the number of shock waves was over 2500 shots.These above findings suggest that shock wave had induced acute changes in renal functions and transient renal tubular damages, although these functional changes recovered within one week, and the tubular damage might last longer than 7 days , In order to avoid serious renal damage, it’s necessary to limit the energy level of shock waves under 12. 5 KV×2500 shots by using JT-3 lithotriptor.

Treatment of urinary lithiasis following kidney transplantation with extracorporeal shock-wave lithotripsy

Background The incidence of urinary lithiasis following kidney transplantation is very low, and decision-supporting data are not available. The aim of this study was to review the diagnosis and treatment of urinary lithiasis following kidney transplantation, which is of realistic significance to reduce urinary lithiasis following kidney transplantation, prolong the survival of renal allografts.Methods The incidence, diagnosis and treatment of urinary lithiasis in ten patients following kidney transplantation were analyzed retrospectively. Seven out of these patients had stones sized approximately 0.4-1.1 cm, and they were treated with low-voltage, low-frequency extracorporeal shock-wave lithotripsy （ESWL）. Two patients had stones sized ＜0.3 cm and they underwent cystoscopy and ureteroscopy. The ureteral catheter endoscopes were inserted in a retrograde manner to mobilize stones repeatedly. After elimination of obstruction, a ureteral double J stent was indwelt.One patient had a pelvic stone （1.2 cm）, which was removed surgically.Results The major clinical manifestations were hematuria, oliguria or anuria. Some patients were asymptomatic and they were diagnosed through laboratory tests and imaging examinations, e.g., ultrasonography. After elimination of obstruction, subjective symptoms disappeared in all patients, and the function of renal allografts recovered. A six-month follow-up indicated no remnant stones or lithiasis relapse.Conclusions The diagnosis and treatment of renal allograft lithiasis are challenging. After prompt and appropriate treatment, the prognosis was satisfactory, and permanent renal functional impairment did not occur in most patients.

Investigation of infection risk and the value of urine endotoxin during extracorporeal shock wave lithotripsy

Objective To clarify the infection risks and the value of endotoxin determination in urine during extracorporeal shock wave lithotripsy (ESWL).Methods According to the distribution and complications of upper urinary calculi, 164 patients were divided into five groups. Group A consisted of 48 patients with 1 to 4 renal calculi, which were or less than 2 crn in diameter. Group B was composed of 24 patients with renal calculus larger than 2 cm in diameter or one to multiple renal calculi. Group C wes composed of 22 patients with 1 to 3 renal calculi accompanied by 1 to 2 ureteric calculi. Group D consisted of 51 patients with 1 to 3 ureteric calculi that were 0.5 to 1.2 cm in diameter, respectively. Group E included 19 patients with complicated renal calculus, such es casting and staghom renal calculus. Urine and blood samples of these patients were obtained before and after ESWL, respectively. Their urine samples were proven sterile prior to treatment. All samples were cultured for bacteria and investigated for endotoxin concentration by the limulus lysate test.Results No significant difference in serum endotoxin wes noted before and after ESWL. Blood bacterial cultures were all negative in all patients after ESWL, similar to those before ESWL. Significant increases in urine endotoxin after ESWL compared with that before ESWL in patients of Groups B, C and E were observed, respectively (P ＜ 0.05). There was no significant difference in urine endotoxin after ESWL compared with that before ESWL in patients of Groups A and D. The positive incidences of urine bacterial culture were significantly increased (P ＜ 0.05) in Groups B and C and very significantly increased ( P ＜ 0.01 ) in Group E compared with those in Groups A and D.Conclusions Urinary infection risk following ESWL was lower in patients with one to several renal calculi,which were less than 2 cm in diameter and did not interfere obviously with the urine flow or in patients with 1 to 3 ureteric calculi that were 0. 5 to 1.2 cm in diameter. The risk was higher in those with complicated calculi, such as casting, staghom renal calculus, renal calculus larger than 2 cm in diameter or renal calculi accompanied by ureteric calculi. For patients with higher infection risk after ESWL, prophylactic antibiotics are necessary even if bacteriuria is not present before ESWL. Endotoxin determination in urine is a reliable,sensitive and simple method for the diagnosis of bacterial infection in patients undergoing ESWL.

Combination of low-energy shock-wave therapy and bone marrow mesenchymal stem cell transplantation to improve the erectile function of diabetic rats

Stem cell transplantation and low-energy shock-wave therapy （LESWT） have emerged as potential and effective treatment protocols for diabetic erectile dysfunction. During the tracking of transplanted stem cells in diabetic erectile dysfunction models, the number of visible stem cells was rather low and decreased quickly. LESWT could recruit endogenous stem cells to the cavernous body and improve the microenvironment in diabetic cavernous tissue. Thus, we deduced that LESWT might benefit transplanted stem cell survival and improve the effects of stem cell transplantation. In this research, 42 streptozotocin-induced diabetic rats were randomized into four groups： the diabetic group （n = 6）, the LESWT group （n = 6）, the bone marrow-derived mesenchymal stem cell （BMSC） transplantation group （n = 15）, and the combination of LESWT and BMSC transplantation group （n = 15）. One and three days after BMSC transplantation, three rats were randomly chosen to observe the survival numbers of BMSCs in the cavernous body. Four weeks after BMSC transplantation, the following parameters were assessed： the surviving number of transplanted BMSCs in the cavernous tissue, erectile function, real-time polymerase chain reaction, and penile immunohistochemical assessment. Our research found that LESWT favored the survival of transplanted BMSCs in the cavernous body, which might be related to increased stromal cell-derived factor-1 expression and the enhancement of angiogenesis in the diabetic cavernous tissue. The combination of LESWT and BMSC transplantation could improve the erectile function of diabetic erectile function rats more effectively than LESWT or BMSC transplantation performed alone.

Sound field prediction of ultrasonic lithotripsy in water with spheroidal beam equations

With converged shock wave, extracorporeal shock wave lithotripsy（ESWL） has become a preferable way to crush human calculi because of its advantages of efficiency and non-intrusion. Nonlinear spheroidal beam equations（SBE） are employed to illustrate the acoustic wave propagation for transducers with a wide aperture angle. To predict the acoustic field distribution precisely, boundary conditions are obtained for the SBE model of the monochromatic wave when the source is located on the focus of an ESWL transducer. Numerical results of the monochromatic wave propagation in water are analyzed and the influences of half-angle, fundamental frequency, and initial pressure are investigated. According to our results, with optimization of these factors, the pressure focal gain of ESWL can be enhanced and the effectiveness of treatment can be improved.

Do available data support the widespread adoption of pancreatoscopy guided-lithotripsy?

Peroral pancreatoscopy(POPS)is a demanding endoscopic procedure that can be used to perform intracanal lithotripsy in obstructing pancreatic stones but the experience is limited.Most stones can be removed successfully by endoscopic retrograde cholangio-pancreatography but patients with large stones require advanced therapeutic approaches,such as extracorporeal shock wave lithotripsy(alone or followed by endoscopic retrograde cholangio-pancreatography),currently the mainstay of treatment.Unfortunately,in about 10%of cases,extracorporeal shock wave lithotripsy can fail;moreover,it is not be available in many institutions.For this subgroup of patients,POPS guided-lithotripsy can play a role and have benefits.The most consistent study concerns a retrospective multicenter analysis that enrolled few patients per center.Considering the epidemiological scenario and the scant volume of skilled endoscopists,POPS must be developed in very few high-volume referral centers with standardized pathways and capable of performing multi-modality treatment.In addition,we could reasonably assume that POPS-guided-lithotripsy should be used as rescue therapy in special situations,identifying the ideal candidate who can achieve the maximum clinical result,and carefully balancing risk/benefits ratio.
