Patel N, Roe A, Stanton D, Roberts J, Kothari A. SLAP Trial: Shock Wave Lithotripsy and Mechanical Percussion Therapy Post ESWL for Renal Calculi. Adv Urol 2024; 2024:7870425. [PMID: 38566931 PMCID: PMC10987243 DOI: 10.1155/2024/7870425] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Revised: 02/27/2024] [Accepted: 03/18/2024] [Indexed: 04/04/2024] Open
Abstract
Methods We conducted a prospective randomised control trial. Included patients were males and females greater than 18 years of age with single or multiple ipsilateral renal calculi of total ≤10 mm on plain X-ray and noncontrast CT KUB. ESWL was performed at a single centre, at supine position under general anaesthesia with maximum 3000 shocks at a rate of 100 shocks per minute. Patients were discharged and randomised to either the control arm or MPI therapy. MPI therapy was self-directed in a home setting for 10 minutes a day, three times per week. Both arms had standard follow-up at 12 weeks with a plain X-ray KUB. Patients in the control group were offered cross over to the MPI arm after 12 weeks if residual stone fragments were detected. Statistical analysis was performed using SPSS software via Chi squared and Fisher's exact tests. Ethical approval was obtained via the Prince Charles Hospital HREC Committee, HREC/2022/QPCH/84961. Results 70 patients met inclusion criteria and underwent ESWL, and 5 were withdrawn. 33 patients were randomised to the MPI group and 32 to the control group. MPI significantly increased the stone clearance rate anywhere in the kidney (87.9% in the MPI group versus 59.4% in the control group, p=0.089), as well as the clearance rate in the lower pole (91.7% in the MPI group versus 63.2% in the control group, p=0.022). Delayed percussion did not improve the clearance rate over primary percussion (p=0.835). Conclusion This study has shown that MPI can be effectively performed in a home setting without the need for medical supervision and results in improved stone clearance rates post ESWL. The main limitations to the study were the use of X-ray over CT during the follow-up and variability in MPI compliance and administration. Further research is warranted into standardising home MPI protocols. This trial is registered with ANZCTR387061.

Abstract
BACKGROUND The stone burden based management strategy reported in the guidelines published by different associations is well known for a long time. Staghorn calculi, representing the largest burden and most complex stones, is one of the most challenging cases to practicing urologists in clinical practice. The International Alliance of Urolithiasis (IAU) has released a series of guidelines on the management of urolithiasis. PURPOSE To develop a series of recommendations for the contemporary management management of staghorn calculi and to provide a clinical framework for urologists treating patients with these complex stones. METHODS A comprehensive literature search for articles published in English between 01/01/1976 and 31/12/2022 in the PubMed, OVID, Embase and Medline database is performed. A series of recommendations are developed and individually graded following the review of literature and panel discussion. RESULTS The definition, pathogenesis, pathophysiology, preoperative evaluation, intraoperative treatment strategies and procedural advice, early postoperative management, follow up and prevention of stone recurrence are summarized in the present document. CONCLUSION A series of recommendations regarding the management of staghorn calculi, along with related commentary and supporting documentation offered in the present guideline is intended to provide a clinical framework for the practicing urologists in the management of staghorn calculi.

Abstract
PURPOSE To investigate the effect of the postural drainage lithotripsy system developed by our experimental team on the vital signs of patient with urinary stones during the stone removal process. METHODS Four groups of 15 subjects (0°, 10°, 40°, and 70°) were subjected to different angles of head-down tilt to measure middle cerebral artery blood flow velocity (MCAv), cerebrovascular conductance coefficient (CVCi), intracranial pressure (nICP), heart rate (HR), and mean arterial blood pressure (MAP). RESULTS As the angle of HDT changed, MCAv values, nICP values, CVCi values, HR values, and MAP values changed significantly (all P ≤ 0.001), and the difference was statistically significant. During 10°HDT, despite a slight increase in nICP, the other measurements remained stable. During 40°HDT, only the MCAv values did not change significantly, whereas the rest of the measures were significantly altered. During 70°HDT, all indicators changed significantly. CONCLUSIONS The significant alterations in cerebral blood flow, intracranial pressure, and hemodynamics induced during the treatment of renal residual fragments with postural drainage should be used with caution in individuals with cerebrovascular accidents.

Abstract
Postural therapy is a postural procedure to fight against the gravity phenomenon responsible for the non-elimination of lower calyceal stones. It allows improving or accelerating their expulsion and it increases the stone-free rate. This procedure associates forced diuresis, postural inversion, and lumbar percussion. It allows a 50% improvement and an acceleration of fragment elimination. Despite its positive impact, postural therapy remains under-used. These are the first practical recommendations on postural therapy. METHODOLOGY: These recommendations were developed using two methods: the Clinical Practice Recommendation (CPR) method and the ADAPTE method, depending on whether the question was considered in the European Association of Urology (EAU) recommendations (https://uroweb.org/guidelines/urolithiasis) [EAU Guidelines on urolithiasis. 2022] and whether they were adaptable to the French context.

Abstract
Nephrolithiasis is a common, painful condition that requires surgery in many patients whose stones do not pass spontaneously. Recent technologic advances have enabled the use of ultrasonic propulsion to reposition stones within the urinary tract, either to relieve symptoms or facilitate treatment. Burst wave lithotripsy (BWL) has emerged as a noninvasive technique to fragment stones in awake patients without significant pain or renal injury. We review the preclinical and human studies that have explored the use of these two technologies. We envision that BWL will fill an unmet need for the noninvasive treatment of patients with nephrolithiasis.

Retrograde intrarenal surgery in lateral position for lower pole stone: an initial experience from Single Academic Hospital. Urolithiasis 2022; 50:199-203. [PMID: 35048132 DOI: 10.1007/s00240-021-01297-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2021] [Accepted: 12/02/2021] [Indexed: 10/19/2022]
Abstract
Retrograde intrarenal surgery (RIRS) was generally challenging in management of lower pole stone (LPS) since the unfavorable anatomy. Theoretically, LPS was prone to fall out and down to renal pelvis when patients turned to lateral position, thus to facilitate lithotripsy. The aim of the present study was to report our initial experience of RIRS in lateral position for LPS. From January 2020 to February 2021, 21 patients with LPS received RIRS in lateral position. The intraoperative finding, operation time, complications and stone-free rate (SFR) were recorded and analyzed. The mean stone size was 16.7 ± 2.4 mm, multiple stones in lower pole were noted in 38.1% (8/21) cases. The mean infundibular-pelvic angle (IPA) was 35.2 ± 6.9°, IPA less than 30° was noted in six cases (28.6%, 6/21). Mean operation time was 43.5 ± 6.3 min. Obvious stone fragments dropping from the lower calyx to renal pelvis during the lithotripsy were noted in 17 cases (81.0%). Only one case (4.8%) suffered postoperative fever (Clavien I), no severe complication (> Clavien II) was noted. Hospital stay was 1.1 ± 0.3 days, the SFR in postoperative 1 month was 85.7%. LPS was prone to fall out and down to renal pelvis when patients in lateral position, thus to facilitate the lithotripsy. RIRS in lateral position was feasible for the management of LPS; however, RCT with large sample was required to certify our initial finding.

Abstract
INTRODUCTION Upper urinary tract calculus is a common disease of the urinary system. AIM To compare the therapeutic effects of flexible ureteroscopy alone and in combination with external physical vibration on upper urinary tract calculi. MATERIAL AND METHODS A total of 146 patients were randomly divided into control and experimental groups (n = 73). The control group received flexible ureteroscopy lithotripsy, and the experimental group underwent the same but combined with external physical vibration. The rate of finding stones in the urine on the day after treatment, clearance rate, components of stones, levels of renal function indices blood urea nitrogen (BUN) and serum creatinine (Scr), and incidence of complications were compared. The stone-free rate during 1-year follow-up was analysed by Kaplan-Meier method. RESULTS The rate of finding stones in the urine on the day after treatment was higher in the experimental group (100%) than that in the control group (29.73%) (p < 0.05). The clearance rates on the day, at 1 week, and at 2 weeks after treatment in the experimental group were 71.23%, 87.67%, and 95.89%, respectively, which surpassed those of the control group at corresponding time points (p < 0.05). BUN and Scr levels decreased after treatment in both groups, especially in the experimental group (p < 0.05). The stone-free rate during 1-year follow-up in the experimental group (n = 71 (97.26%)) exceeded that of the control group (n = 61 (83.56%)) (p < 0.05). CONCLUSIONS External physical vibration combined with flexible ureteroscopy lithotripsy significantly increased the rate of finding stones in the urine the day after treatment, the clearance rate of upper urinary tract calculi, and the ameliorated renal function and reduced the stone re-formation rate.

Abstract
Introduction To evaluate the efficacy and safety of preforming extracorporeal physical vibration lithecbole(EVPL)through greater sciatic foramen(GSF)for distal ureteral calculi(DUC) treatment. Materials and methods All patients with a diagnosis of DUC (6 - 10 mm in diameter) were enrolled in this study from October 2018 to May 2020. Patients were randomly divided into three groups receiving EPVL through GSF (Group A, n = 58), or abdominal (Group B, n = 60), or combined with oral use of tamsulosin at 0.4 mg daily (Group C, n = 63). Results There was no significant difference observed in terms of demographic characteristics or size of stones among the three groups (p >0.05). Compared with the group B and C, patients of the group A displayed a significantly higher score of comfort but with significantly decreased number of renal colic attacks or analgesics required (p < 0.01). The stone-free rate also significantly increased after one and two weeks of treatment (p < 0.01), despite such a significant difference among these groups vanished after four weeks of treatment. Conclusion Extracorporeal physical vibrational lithecbole in the prone position use the greater sciatic foramen as the path is the safe and effective approach to treat the distal ureter calculi.

Abstract
Abstract
Background
Small renal calculi are frequently observed in clinical practice, and chemo-lytic therapy has limited effects. The purpose of the study is to evaluate the effectiveness of extracorporeal shock wave lithotripsy (ESWL) in the treatment of small renal calculi.
Methods
We studied 60 patients with small renal stones from March 2017 to March 2019. After excluding eight patients with incomplete data, the remaining 52 patients were evaluated. Patients with symptomatic single or multiple stones of 6–8 mm in diameter or asymptomatic on ultrasound and kidney-ureter-bladder radiograph were eligible for inclusion. Small stones were treated by ESWL. The data were analyzed using the Statistical Packages for Social Sciences - version 25 (IBM Corporation).
Results
The mean age of the 52 patients was 34.5 ± 9.5 years. Forty-one (78.8%) patients were symptomatic, while 11 (21.2%) were asymptomatic. Forty-seven (90.4%) had single small renal stones, while four patients had two stones (7.7%) and only one patient had three stones (1.9%). Forty-five stones were successfully treated by ESWL, while 13 stones failed to respond.
Conclusion
ESWL is a useful tool for treating small renal calculi; it works either by fragmenting the stones or by acting as a pushing force. However, further large prospective studies are needed to corroborate the above conclusions.

Abstract
Introduction: The current study evaluated the efficacy and safety of external physical vibration lithecbole (EPVL) after extracorporeal shock wave lithotripsy (SWL) or retrograde intrarenal surgery (RIRS) for urolithiasis. Methods: Publicized literature was systematically searched from EMBASE, Cochrane Library, PubMed, ScienceDirect, ClinicalTrials.gov, and Web of Science up to February 2020. Fixed-effects or random-effects model was chosen in risk ratio (RR) calculation according to heterogeneity. Quality of evidence was estimated under the guidance of Cochrane handbook. Stone expulsion rate, stone-free rates (SFRs), and complication rates were set as end points. Results: Six randomized controlled trials, including 853 patients, were eligible for analysis. EPVL significantly increased SFR within 3 weeks (RR = 1.17, 95% CI: 1.06-1.29, P = 0.001) and above 3 weeks (RR = 1.19, 95% CI: 1.03-1.37, P = 0.02) after SWL. EPVL also improved SFR within 3 weeks (RR = 1.84, 95% CI: 1.35-2.49, P < 0.0001) and above 3 weeks (RR = 1.53, 95% CI: 1.33-1.77, P < 0.00001) after RIRS. Besides, EPVL can significantly increase SFRs for stones in renal pelvis, lower calix, and multiple locations (all P-value <0.05). Although the overall complication rate was not significantly higher in EPVL + RIRS group, it was found to be 1.38 times higher in EPVL+SWL group (RR = 1.38, 95% CI: 1.06-1.79, P = 0.02), especially the incidence of flank pain (RR = 3.11, 95% CI: 1.02-9.46, P = 0.05). Conclusions: EPVL is effective and safe with high SFRs (especially in renal pelvis, lower calix, and multiple locations) after SWL or RIRS and lower overall complication rate after RIRS in patients with urolithiasis. However, the overall complication rate (especially the incidence of flank pain) was higher after EPVL + SWL.

Peng L, Wen J, Zhong W, Zeng G. Is physical therapy effective following extracorporeal shockwave lithotripsy and retrograde intrarenal surgery: a meta-analysis and systematic review. BMC Urol 2020; 20:93. [PMID: 32646402 PMCID: PMC7350681 DOI: 10.1186/s12894-020-00664-9] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2019] [Accepted: 06/30/2020] [Indexed: 12/21/2022] Open
Abstract
Background Physical therapy, including percussion, inversion, vibration and combinations, was clinically performed to improve the stone free rate (SFR) following lithotripsy procedures. However, physical therapy is not widely accepted in clinical practice owing to lack of high level evidence support and a standard protocol. The present meta-analysis aimed to evaluate the efficacy and safety of physical therapy in improving SFR following extracorporeal shockwave lithotripsy (ESWL) and retrograde intrarenal surgery (RIRS). Methods Systematic review of literature from PubMed, Scopus, Cochrane library and Embase was performed in March 2019. The efficacy and safety of physical therapy after ESWL and RIRS were assessed by meta-analysis of SFR and complication rate. Results A total of 8 prospective studies with 1065 patients were enrolled. When compared to non-intervention, physical therapy provided a higher SFR (OR:3.38, 95% CI: 2.45–4.66, p < 0.0001) at all time points (week 1, week 2 and month 1), while there was no significant difference in complications such as hematuria, lumbago, dizziness and urinary tract infection (OR: 0.84; 95%CI: 0.62–1.13; p = 0.237). In subgroup analysis of different stone locations, lower calyx stone (OR: 3.51; 95%CI: 2.21–5.55; p < 0.0001), upper ureter and renal pelvic stones (OR:2.79; 95%CI:1.62–4.81; p = 0.0002) had a higher SFR after physical therapy, while there was no significant improvement in SFR in upper and middle calyx stones. In subgroup analysis of different techniques, EPVL (external physical vibration lithecbole, OR:3.47; 95%CI:2.24–5.37; p < 0.0001) and PDI (percussion, diuresis and inversion, OR:3.24; 95%CI:2.01–5.21; p < 0.0001) were both effective in improving SFR when compared to non-intervention. Conclusions Physical therapy is effective in improving the SFR after ESWL and RIRS, especially for lower calyx stones, upper ureter and renal pelvic stones, while without significant side effects. External physical vibration lithecbole (EPVL) might provide a relative uniformed and repeatable protocol for clinical practice of physical therapy. Trial registration PROSPERO 2019 CRD42019130228.

Abstract
To determine the best time to perform EPVL treatment by evaluating the efficacy and safety of active stone extraction in treating residual fragments at different time points after RIRS. All participants had renal or upper ureteral stones preoperatively and still had residual stones after receiving RIRS. They were prospectively randomized into four groups: patients in group A received EPVL 3 days after RIRS; patients in group B received EPVL 7 days after RIRS; patients in group C received EPVL 14 days after RIRS; patients in group D did not receive EPVL after RIRS. Follow-up examinations were performed on all participants. The results, including stone size and location, stone-free rate (SFR) and complications, were compared among the groups. There were 176 patients in total. The SFR in groups A, B, C and D were 62.22%, 40.91%, 14.28% and 11.11%, respectively, 7 days after RIRS. At 14 days after RIRS, the SFR was 80%, 59.09%, 42.86% and 26.67% in groups A, B, C and D, respectively. At 28 days after RIRS, the SFR was 91.11%, 84.09%, 76.19% and 51.11% in groups A, B, C and D, respectively. Group A had the highest SFR from 7 to 28 days, and group C had a higher SFR at 28 days after RIRS than group D (P < 0.05). The side effects were less in groups A and B than in group D 28 days after RIRS (P < 0.05). We recommended that the best time to perform EPVL is 3 days after RIRS, because it could achieve a high SFR at any point in time and reduced complications.

Abstract
This article reviews new advances in ultrasound technology for urinary stone disease. Recent research to facilitate the diagnosis of nephrolithiasis, including use of the twinkling signal and posterior acoustic shadow, have helped to improve the use of ultrasound examination for detecting and sizing renal stones. New therapeutic applications of ultrasound technology for stone disease have emerged, including ultrasonic propulsion to reposition stones and burst wave lithotripsy to fragment stones noninvasively. The safety, efficacy, and evolution of these technologies in phantom, animal, and human studies are reviewed herein. New developments in these rapidly growing areas of ultrasound research are also highlighted.

Abstract
The Urological Association of Asia, consisting of 25 member associations and one affiliated member since its foundation in 1990, has planned to develop Asian guidelines for all urological fields. The field of stone diseases is the third of its guideline projects. Because of the different climates, and social, economic and ethnic environments, the clinical practice for urinary stone diseases widely varies among the Asian countries. The committee members of the Urological Association of Asia on the clinical guidelines for urinary stone disease carried out a surveillance study to better understand the diversity of the treatment strategy among different regions and subsequent systematic literature review through PubMed and MEDLINE database between 1966 and 2017. Levels of evidence and grades of recommendation for each management were decided according to the relevant strategy. Each clinical question and answer were thoroughly reviewed and discussed by all committee members and their colleagues, with suggestions from expert representatives of the American Urological Association and European Association of Urology. However, we focused on the pragmatic care of patients and our own evidence throughout Asia, which included recent surgical trends, such as miniaturized percutaneous nephrolithotomy and endoscopic combined intrarenal surgery. This guideline covers all fields of stone diseases, from etiology to recurrence prevention. Here, we present a short summary of the first version of the guideline - consisting 43 clinical questions - and overview its key practical issues.

External physical vibration lithecbole facilitating the expulsion of upper ureteric stones 1.0-2.0 cm after extracorporeal shock wave lithotripsy: a prospective randomized trial. Urolithiasis 2018; 48:71-77.

Abstract
To observe the efficacy and safety of External Physical Vibration Lithecbole (EPVL) in patients with upper ureteric stones 1.0–2.0 cm after extracorporeal shock wave lithotripsy (ESWL). A total of 271 patients with upper ureteric stones 1.0–2.0 cm were prospectively randomized into two groups. One hundred and twenty-seven cases in the treatment group accepted EPVL therapy and 144 cases as control after ESWL. The stone expulsion status and stone-free rates (SFRs) between two groups were compared at the 1st, 2nd and 4th weekends by imaging examinations. All of 271 patients were randomly assigned to two groups, of which 127 patients were included in the treatment group and 144 in the control group. EPVL was successful in assisting the discharge of stone fragments. The rate of stone expulsion at day 1 in the treatment group was significantly higher than in the control group (79.5% vs. 64.6%, P = 0.006). The SFRs of the 1st weekend (76.3% vs. 61.8%, P = 0.010), the 2nd weekend (88.2% vs. 77.1%, P = 0.017) and the 4th weekend (92.1% vs. 84.0%, P = 0.042) in the treatment group were all significantly higher than that in the control group. However, no statistical significance was found in complications between the two groups (P > 0.05). Furthermore, in the treatment group the patients were treated a mean 4.3 sessions of EPVL. EPVL and ESWL are ideal complementary partners in the treatment of upper ureteric stones 1.0–2.0 cm, satisfying both high SFR and low complication. This method is safe and reproducible in clinical practice, and it also needs large-scale multicenter prospective studies further to prove the above conclusions.

Abstract
OBJECTIVE To asset the efficacy and safety of EPVL plus ESWL compared with ESWL alone for the treatment of simple upper urinary stones (< 15 mm). MATERIALS AND METHODS All patients with upper urinary stones (< 15 mm) were prospectively randomized into two groups. In treatment group, patients were assigned to immediate EPVL after ESWL, while in control group, ESWL alone was offered. All patients were reexamined at 1, 2, and 4 weeks after ESWL. Stone size, stone location, stone-free rate (SFR), and complication rate were compared. RESULTS 56 males and 20 females in treatment group were compared to 52 male and 25 females in control group (p = 0.404). Median ages were 42.9 ± 1.5 years in treatment group and 42.7 ± 1.3 years in control group (p = 0.943). Median stone size was 10.0 ± 0.4 mm (3-15 mm) in treatment group and 10.4 ± 0.4 mm (4-15 mm) in control group (p = 0.622). The stone clearance rate in treatment and control group at 1 week after ESWL was 51.3% (39/76) and 45.4% (35/77) (p > 0.05), at 2 weeks was 81.6% (62/76) and 64.9% (50/77) (p < 0.05), and at 4 weeks was 90.8% (69/76) and 75.3% (58/77) (p < 0.05), respectively. CONCLUSIONS EPVL is a noninvasive, effective, and safe adjunctive treatment which increases and accelerates upper urinary stones discharge after ESWL treatment.

Abstract
INTRODUCTION The obstruction of the urinary tract by calculi at the narrowest anatomical areas leads to impaired drainage and severe pain. The aim of this study was to evaluate a new technology, extracorporeal physical vibrational lithecbole (EPVL) combined with tamsulosin, as a treatment for distal ureteral calculi (DUC). MATERIALS AND METHODS Between July 2013 and July 2014, 672 patients diagnosed with DUC were randomly divided into three groups; a group receiving EPVL plus 0.4 mg oral tamsulosin daily (PO qd) (experimental group, n = 236), a group receiving 0.4 mg tamsulosin PO qd (n = 222), and a group receiving EPVL only (n = 214) (control groups). RESULTS There were no significant differences in general characteristics between the three groups. Stone diameters ranged from 0.32 to 1 cm. In the EPVL plus tamsulosin group, 60.1% of patients showed detectable fragment expulsion at 48 hours, and 91.1% were stone free at 7 days. Compared with the two control groups, these rates were significantly higher (EPVL group was 0% and 50.5% and medical expulsive therapy group was 0% and 50.0%, p < 0.05). The stone-free rates were similar in the three groups 2 weeks later (94.5%, 93.6%, and 93.5%; p > 0.05). Patients in the EPVL plus tamsulosin group achieved similar stone-free rates compared with the other two groups, but the speed of the stone expulsion was quicker for both sexes and all age groups (about a week; p < 0.05). CONCLUSION This indicates that EPVL plus tamsulosin could be used as an effective, but faster treatment option for patients with DUC, alleviating the symptoms of DUC in a shorter period of time.
