Management of urinary stones: state of the art and future perspectives by experts in stone disease. Arch Ital Urol Androl 2024; 96:12703. [PMID: 38934520 DOI: 10.4081/aiua.2024.12703] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2024] [Accepted: 06/13/2024] [Indexed: 06/28/2024] Open
Abstract
AIM To present state of the art on the management of urinary stones from a panel of globally recognized urolithiasis experts who met during the Experts in Stone Disease Congress in Valencia in January 2024. Options of treatment: The surgical treatment modalities of renal and ureteral stones are well defined by the guidelines of international societies, although for some index cases more alternative options are possible. For 1.5 cm renal stones, both m-PCNL and RIRS have proven to be valid treatment alternatives with comparable stone-free rates. The m-PCNL has proven to be more cost effective and requires a shorter operative time, while the RIRS has demonstrated lower morbidity in terms of blood loss and shorter recovery times. SWL has proven to be less effective at least for lower calyceal stones but has the highest safety profile. For a 6mm obstructing stone of the pelviureteric junction (PUJ) stone, SWL should be the first choice for a stone less than 1 cm, due to less invasiveness and lower risk of complications although it has a lower stone free-rate. RIRS has advantages in certain conditions such as anticoagulant treatment, obesity, or body deformity. Technical issues of the surgical procedures for stone removal: In patients receiving antithrombotic therapy, SWL, PCN and open surgery are at elevated risk of hemorrhage or perinephric hematoma. URS, is associated with less morbidity in these cases. An individualized combined evaluation of risks of bleeding and thromboembolism should determine the perioperative thromboprophylactic strategy. Pre-interventional urine culture and antibiotic therapy are mandatory although UTI treatment is becoming more challenging due to increasing resistance to routinely applied antibiotics. The use of an intrarenal urine culture and stone culture is recommended to adapt antibiotic therapy in case of postoperative infectious complications. Measurements of temperature and pressure during RIRS are vital for ensuring patient safety and optimizing surgical outcomes although techniques of measurements and methods for data analysis are still to be refined. Ureteral stents were improved by the development of new biomaterials, new coatings, and new stent designs. Topics of current research are the development of drug eluting and bioresorbable stents. Complications of endoscopic treatment: PCNL is considered the most invasive surgical option. Fever and sepsis were observed in 11 and 0.5% and need for transfusion and embolization for bleeding in 7 and 0.4%. Major complications, as colonic, splenic, liver, gall bladder and bowel injuries are quite rare but are associated with significant morbidity. Ureteroscopy causes less complications, although some of them can be severe. They depend on high pressure in the urinary tract (sepsis or renal bleeding) or application of excessive force to the urinary tract (ureteral avulsion or stricture). Diagnostic work up: Genetic testing consents the diagnosis of monogenetic conditions causing stones. It should be carried out in children and in selected adults. In adults, monogenetic diseases can be diagnosed by systematic genetic testing in no more than 4%, when cystinuria, APRT deficiency, and xanthinuria are excluded. A reliable stone analysis by infrared spectroscopy or X-ray diffraction is mandatory and should be associated to examination of the stone under a stereomicroscope. The analysis of digital images of stones by deep convolutional neural networks in dry laboratory or during endoscopic examination could allow the classification of stones based on their color and texture. Scanning electron microscopy (SEM) in association with energy dispersive spectrometry (EDS) is another fundamental research tool for the study of kidney stones. The combination of metagenomic analysis using Next Generation Sequencing (NGS) techniques and the enhanced quantitative urine culture (EQUC) protocol can be used to evaluate the urobiome of renal stone formers. Twenty-four hour urine analysis has a place during patient evaluation together with repeated measurements of urinary pH with a digital pH meter. Urinary supersaturation is the most comprehensive physicochemical risk factor employed in urolithiasis research. Urinary macromolecules can act as both promoters or inhibitors of stone formation depending on the chemical composition of urine in which they are operating. At the moment, there are no clinical applications of macromolecules in stone management or prophylaxis. Patients should be evaluated for the association with systemic pathologies. PROPHYLAXIS Personalized medicine and public health interventions are complementary to prevent stone recurrence. Personalized medicine addresses a small part of stone patients with a high risk of recurrence and systemic complications requiring specific dietary and pharmacological treatment to prevent stone recurrence and complications of associated systemic diseases. The more numerous subjects who form one or a few stones during their entire lifespan should be treated by modifications of diet and lifestyle. Primary prevention by public health interventions is advisable to reduce prevalence of stones in the general population. Renal stone formers at "high-risk" for recurrence need early diagnosis to start specific treatment. Stone analysis allows the identification of most "high-risk" patients forming non-calcium stones: infection stones (struvite), uric acid and urates, cystine and other rare stones (dihydroxyadenine, xanthine). Patients at "high-risk" forming calcium stones require a more difficult diagnosis by clinical and laboratory evaluation. Particularly, patients with cystinuria and primary hyperoxaluria should be actively searched. FUTURE RESEARCH Application of Artificial Intelligence are promising for automated identification of ureteral stones on CT imaging, prediction of stone composition and 24-hour urinary risk factors by demographics and clinical parameters, assessment of stone composition by evaluation of endoscopic images and prediction of outcomes of stone treatments. The synergy between urologists, nephrologists, and scientists in basic kidney stone research will enhance the depth and breadth of investigations, leading to a more comprehensive understanding of kidney stone formation.

[PMID: 38462437 DOI: 10.1016/j.sapharm.2024.02.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Revised: 02/20/2024] [Accepted: 02/25/2024] [Indexed: 03/12/2024]
Abstract
BACKGROUND The global increase in kidney stone incidence and its complications emphasise the need for effective management. While pharmacists can play a significant role in counselling and guiding patients, their practices in managing patients with kidney stones remain unclear. OBJECTIVE(S) To explore counselling practices and experiences of pharmacists when dealing with patients with kidney stones and to identify the barriers they face while providing counselling. METHODS A qualitative study was performed using semi-structured phone interviews with pharmacists practising in Jordan. Pharmacists were selected using quota sampling from those who took part in a previous study focused on pharmacists' knowledge of kidney stone aetiology and treatment. The COM-B Model of Behaviour Change was used to develop the interview guide and the analytical framework. Interviews were transcribed verbatim and analysed using a deductive thematic approach based on the pre-specified analytical framework. RESULTS Seven pharmacists (85.7% female; 57.1% working in community pharmacies) were interviewed. Counselling practices of patients with kidney stones were categorised into five themes: (1) Pharmacists' beliefs about patient counselling: perceived importance and desire to improve health through counselling; (2) Most priority patients: Types of patients mostly counselled; (3) Content of kidney stones-specific counselling: patient assessment and recommendations about kidney stones management; (4) Duration of the counselling sessions: time offered and influencing factors; (5) Barriers to patient counselling: patient-related, and pharmacist- and doctor-related challenges. CONCLUSIONS Pharmacists recognise the crucial role of kidney stones counselling but face gaps in their practices, including incomplete dietary education, limited knowledge of medication prescriptions, inconsistent patient-specific approaches, and potential communication challenges. These gaps can be overcome by enhancing training, standardising protocols of kidney stone treatment, promoting interprofessional communication, and improving communication strategies. Future research, including quantitative assessments, is needed to inform strategies that optimise patient counselling practices and facilitate improved outcomes.

Promoting fluid intake to increase urine volume for kidney stone prevention: Protocol for a randomized controlled efficacy trial of the sip IT intervention. Contemp Clin Trials 2024; 138:107454. [PMID: 38253254 PMCID: PMC10923155 DOI: 10.1016/j.cct.2024.107454] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2023] [Revised: 01/11/2024] [Accepted: 01/19/2024] [Indexed: 01/24/2024]
Abstract
BACKGROUND Risk of kidney stone recurrence can be reduced by increasing fluid intake and urine production but most patients fail to adhere to recommended clinical guidelines. Patients have indicated that common barriers to fluid intake include a lack of thirst, forgetting to drink, and not having access to water. We developed the sipIT intervention to support patients' fluid intake with semi-automated tracking (via a mobile app, connected water bottle and a smartwatch clockface that detects drinking gestures) and provision of just-in-time text message reminders to drink when they do not meet the hourly fluid intake goal needed to achieve the recommended volume. This trial evaluates the efficacy of sipIT for increasing urine output in patients at risk for recurrence of kidney stones. METHOD/DESIGN Adults with a history of kidney stones and lab-verified low urine production (<2 L/day) will be randomly assigned to receive either usual care (education and encouragement to meet fluid intake guidelines) or usual care plus the sipIT intervention. The primary outcome is 24-h urine volume; secondary outcomes include urinary supersaturations, past week fluid intake, and experienced automaticity of fluid intake. Outcomes will be assessed at baseline, 1 month, 3 months, and 12 months. CONCLUSIONS The sipIT intervention is the first to prompt periodic fluid intake through integration of just-in-time notifications and semi-automated tracking. If sipIT is more efficacious than usual care, this intervention provides an innovative treatment option for patients needing support in meeting fluid intake guidelines for kidney stone prevention.

Abstract
PURPOSE OF REVIEW The purpose of this review is to examine the use of technology to help promote and maintain behaviors that decrease stone recurrence. RECENT FINDINGS Behavior change is a complex process with various interacting components. Recent developments have sought to utilize technology in combination with behavioral change techniques to promote behavior that lowers stone recurrence risk. Smart water bottles are becoming a popular way to accurately measure fluid intake with variable impact on adherence to the recommended daily fluid intake. Mobile apps have also been explored as a method to improve fluid intake. Interventions that combine smart water bottles, mobile apps, and behavioral change techniques have shown the most promise in promoting increased daily fluid intake. Other technologies, such as smart pill dispensers and hydration monitors, have potential applications in promoting behavioral change for stone disease but have yet to be evaluated for this purpose. SUMMARY There is a limited number of studies exploring technology as a means to promote and maintain behaviors that decrease urinary stone recurrence. Future research is needed to elucidate how to maximize the potential of these technologies and better understand which behavioral change techniques best promote habit formation for the prevention of stones.

Abstract
BACKGROUND Dietary habit is one of the most important methods to prevent and treat urinary stones. However, only limited evidence of the experiences of dietary management among urinary stone patients in Malaysia is available. This study aimed to explore participants' current dietary practices after the diagnosis of urinary stones and to identify the factors that facilitate their dietary changes. METHODS A qualitative study with purposive sampling was conducted using face-to-face semistructured interviews. A total of 20 participants from a tertiary general hospital in Kuantan, Malaysia, were recruited in this study. Data were analysed using framework analysis. RESULTS Two themes emerged from the analysis. The first theme explained the changes in the dietary practice of the participants postdiagnosis. The second theme revealed that the participants' dietary changes were greatly influenced by personal factors and external support from professionals, family and peers. CONCLUSIONS Urinary stone patients highlighted the fear of complications, self-determination and knowledge of nutrition as the main drivers of their dietary change postdiagnosis. Emphasising proper nutritional care by assessing and evaluating dietary self-management among patients can facilitate effective self-care in stone prevention management.

Abstract
Urinary stone disease continues to be a public health problem with growing incidence and recurrences. Recurrence is nearly detected in 50% of the patients within 5 years after the first episode. However, stone recurrence rates can be reduced to a certain extent. The American Urological Association (AUA) and the European Urological Association (EAU) guidelines advice dietary, fluid intake, and medical treatment to prevent or minimize stone recurrence. However, studies have shown that compliance to dietary and fluid intake recommendations is low. Beside this, nutritional evaluation of the patients is sufficient. Using food frequency questionnaires (FFQs), 24 h recall methods (short, individual-oriented, and easily applicable) or mobile apps can be used. In addition, cooperation with registered dietitians (RD) and planning tailored dietary programmes may have positive effect on compliance. Providers who give dietary advices should improve their knowledge about the topic and communication skills to create a patient-provider trust relationship. Simplifying the advices (shorter lists, applicable advices), spending more time, and giving education until being sure for patients' understanding with regular remindings may improve adherence. Moreover, patients increased awareness and knowledge about dietary advices are beneficial. Smart devices for fluid uptake or urine pH monitoring, mobile apps or web-based portals, and telemedicine applications can be used to maintain the compliance on dietary advices. Compliance with dietary modifications and fluid intake recommendations can be well achieved by individualized evaluation/close follow-up and the elimination of the problems limiting the patient compliance.

Abstract
Study objective
To study the effect of a herbal preparation containing a standardised BNO 1040 extract* (based on lovage root, rosemary leaves and aerial parts of centaury) on the extracorporeal shockwave lithotripsy (ESWL) results in patients with urolithiasis (UL).
Methodology
150 patients with UL (aged 18–65 years) treated with ESWL method were divided into 2 equal groups. The main group (n = 75) received standard recommendations and herbal preparation (12 months). The control group (n = 75) received standard recommendations only. The following was evaluated: time and degree of elimination of fragments; the presence of pain and leukocyturia; recurrent stone formation.
Results
The elimination of fragments was observed up to 14 days in 94.7% of patients in the main group versus 76% of patients in the control group. Renal colic was observed in 6.7% of patients in the main group versus 10.7% of patients in the control group; cases of leukocyturia were observed within 14 days in 10.7% versus 22.7%, respectively. During the year, a recurrent lithiasis was diagnosed in 6.7% of patients in the main group and in 16% of patients in the control group.
Conclusion
The use of BNO 1040 extract in combination with ESWL: contributes to more rapid and safe elimination of fragments of the calculi and reduces the risk of recurrent stone formation.

Abstract
The purpose of this study in a small group of non-stone-forming Chinese persons was to measure the levels of supersaturation with calcium oxalate and calcium phosphate and pH with the aim of confirming if any of the different short-term urine samples were better for risk evaluation than a 24-h sample. Nine normal men and 1 woman collected urine during 4 periods of the day. Period 1 between 08 and 12 h, Period 2 between 12 and 18 h, Period 3 between 18 and 22 h, and Period 4 between 22 and 08 h. Each sample was analysed for calcium, oxalate, citrate, magnesium and phosphate, and estimates of supersaturation with calcium oxalate (CaOx) and calcium phosphate (CaP) were expressed in terms of AP(CaOx) and AP(CaP) index. An estimate of the solute load of CaOx was also calculated. Urine composition for 24-h urine (Period 24) was obtained mathematically from the analysed variables. Urine composition corresponding to 14-h urine portions 22-12 h (Period 14N) and 08-22 h (Period 14 D) were calculated. The lowest pH levels were recorded in Period 1 urine. The highest level of AP(CaOx) index was recorded during Period 1, and the product AP(CaOx) index × 107 × hydrogen ion concentration was significantly higher in Period 1 urine than in 24-h urine (p = 0.02). Also, the product SL(CaOx) × 107 × hydrogen ion concentration was significantly higher in Period 1 urine (p = 0.02). Low AP (CaP) index levels were recorded in Period 4, but also in all periods following dietary loads of calcium and phosphate. With the important reservation that the analytical results were obtained from non-stone-forming persons, the conclusion is that analysis of urine samples collected between 08 and 12 h might be an alternative to 24-h urine. The risk evaluation might advantageously be expressed either in terms of the product AP(CaOx) index × 107 × hydrogen ion concentration or the product SL(CaOx) × 107 × hydrogen ion concentration.

Proposal for the User-Centered Design Approach for Health Apps Based on Successful Experiences: Integrative Review. JMIR Mhealth Uhealth 2020; 8:e14376. [PMID: 32319965 PMCID: PMC7203616 DOI: 10.2196/14376] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2019] [Revised: 11/05/2019] [Accepted: 01/26/2020] [Indexed: 12/31/2022] Open
Abstract
Background Different strategies encompassed within mHealth have shown themselves to be effective for maintaining good health or controlling certain diseases. However, there is usually a very high rate of abandonment of health apps. Therefore, it would seem obvious that there is a need for involving the end users (whether they are health professionals, patients, or both) in the design process from the early stages in order to enable their needs and characteristics to be identified. In this sense, it is common knowledge that focusing on the user permits the consideration of valuable details aimed at making the correct adjustment between the patient, the technology, and the organization of attention. Objective The goal of the research was to propose a methodology based on the review of previous successful user experiences in setting up health apps by using qualitative techniques (focus groups and discussion groups) that includes the participation of information technology and health professionals and the patients themselves. Methods An integrative review was made of studies in which a qualitative methodology was employed mainly through focus and/or discussion groups for the design and development of health apps, consulting diverse databases (PubMed, Scopus, and Proquest) with the following search strategy: “mHealth AND apps AND focus group OR discussion group.” A total of 69 papers were included in the review. Results A proposal structured in 4 sessions of variable duration was made in which information technology and health professionals and patients take part: composing, preparing, and organizing contents (session 1); testing structure and usability (session 2); does the app fit the needs of end users? (session 3); and last testing—keep on improving (session 4). Throughout the sessions, we propose studying aspects like previous user experiences in mHealth, barriers to the adoption of mHealth, interface contents, management and browsability, usability, perceived quality, security and privacy, capacity to self-manage disease with the app, ergonomics, and glanceability, etc. Specific tools that have proved useful in previous research for measuring these aspects are presented. Conclusions These work sessions would be based on predominantly qualitative methodologies although, as they evolve, validated questionnaires permitting the assessment of the objectivity of certain technical aspects could be incorporated. With this proposal, a project centered on end users could be effected, responding to their needs. However, this requires validation that will be made via implementation in the development of health apps, with the subsequent measurement of results in terms of adherence and improvement in the clinical variables of the end users.

Abstract
Crystal modulators play a significant role in the formation of calcium oxalate stone disease. When renal cells are subjected to oxalate stress, the loss in cell integrity leads to exposure of multiple proteins that assist and/or inhibit crystal attachment and retention. Contact between oxalate and calcium oxalate with urothelium proves fatal to cells as a result of reactive oxygen species generation and onset of oxidative stress. Hence, as a therapeutic strategy it was hypothesised that supplementation of antioxidants would suffice. On the contrary to popular belief, the detection of oxalate induced endoplasmic reticulum mediated apoptosis proved the ineffectiveness of antioxidant therapy alone. Thus, the inadequacy of antioxidant supplementation in oxalate stress invoked the presence of an alternative pathway for the induction of kidney fibrosis in hyperoxaluric rats. In addition to settling this query, the link between oxidative stress and ER stress is not well understood, especially in urolithiasis.

Abstract
The study objective was to analyse the effect of the herbal drug Canephron N, namely, its ability to potentiate the efficacy of extracorporeal shock wave lithotripsy (ESWL) in the treatment of patients with urolithiasis (UL) and prevent recurrence of stone formation.
Aim. To сheck the hypothesis that treatment with Canephron N can potentiate lithotripsy and reduce the risk of re-stone formation.
Methodology. Patients at the age of 18 to 65 years had calcium oxalate urolithiasis with the size of the stone from 0.8 to 1.3 cm in the kidneys and from 0.5 to 0.9 cm. in ureters who underwent ESWL procedure. They were randomized into 2 equal groups of 30 people. The treatment group received general recommendations on the management of the patient with UL following ESWL and the herbal drug Canephron N for 6 months. The control group received only general recommendations. Moreover, according to condition, both groups received painkillers and spasmolytics if pain occurred during elimination of fragments. The following parameters were evaluated: the period of elimination of fragments after stone disintegration by ESWL method; the percentage of complete elimination of fragments; the presence of pain syndrome and leukocyturia in the postoperative period; the rate of recurrence of stone formation during one year after the procedure.
Results. More complete and rapid elimination of fragments was observed in the treatment group. Thus, up to day 14 elimination of stone fragments was observed in 96.6 % of patients in the treatment group versus 76.6 % in the control group. Fewer cases of pain syndrome during elimination of stone fragments (23 % in the treatment group and 43 % in the control group) and rare cases of leukocyturia within 14 days (10 % versus 23 %, respectively) were observed in the treatment group. Recurrent stone formation within the year was not observed in patients of the treatment group, in the control group – in 23 % of patients. However, because of the small size of the groups, one may talk about a tendency but not about statistically significant patterns.
Conclusion. Canephron N is an effective and safe drug in the treatment of patients with urolithiasis who underwent extracorporeal shock wave lithotripsy. Its use contributes to more rapid and safe elimination of fragments of destructed calculi and reduces risk of recurrent stone formation.

Abstract
OBJECTIVE To evaluate kidney stone patients' interest in lifestyle behavior modification and a variety of mobile health (mHealth) technologies to improve adherence to fluid consumption recommendations for the prevention of nephrolithiasis. Of particular interest was the acceptability of various intervention components for the design of a stone-specific mHealth technology. MATERIALS AND METHODS Using a cross-sectional design, adult patients with a diagnosis of kidney stones (n = 94) were recruited from outpatient clinics to complete a three-part questionnaire. RESULTS Patients reported being willing to make lifestyle changes to prevent kidney stones (97%). The majority of the patients recalled the recommendation to increase fluid intake (93%) but few monitored their daily fluid intake (30%). Most patients had never installed an app (95%) or owned a device (100%) to help with increasing fluid consumption, but believed an app or device could improve their adherence (72%) and would be interested in using an app or device (86%). The mHealth intervention components most widely perceived as useful included automated lapse detection with notifications, educational materials, self-monitoring tools, scheduler with prompts and/or reminders and/or notifications, connected water bottles and text message reminders to drink. CONCLUSION Patients are interested in lifestyle behavior change to prevent stones but technology has not been widely adopted to improve adherence to fluid intake recommendations for stone prevention. This study identified a number of viable mHealth intervention components that should be considered when designing a stone-specific mHealth technology to support adherence to increased fluid consumption recommendations.

Timelines of the "free-particle" and "fixed-particle" models of stone-formation: theoretical and experimental investigations. Urolithiasis 2016; 45:33-41. [PMID: 27915394 PMCID: PMC5250668 DOI: 10.1007/s00240-016-0946-x] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2016] [Accepted: 11/22/2016] [Indexed: 12/11/2022]
Abstract
Two major theories on renal stone formation will be reviewed, the “free-particle” and “fixed-particle” mechanisms. These theories combine data on intrinsic factors (inborn metabolic errors), extrinsic factors (diet), renal cell responses and the physico-chemistry and biochemistry of urine into mechanisms of stone formation. This paper describes the specific role of time in both mechanisms. The timeline of crystal- and stone formation was deducted from literature data and was measured for two stones using radioisotope decay analysis. The stones of similar size and composition showed, respectively, a timeline of a few years and a development that took decades. In combination with data on stone architecture and patient characteristics these timelines are explained using the free-particle and fixed-particle mechanisms. Consideration of the timeline of stone formation has clinical implications. We conclude that the fixed-particle mechanism can be a slow process where decades pass between the first formation of a precipitate in the renal interstitium and the clinical presentation of the stone. Added to the fact that the mechanism of this initial precipitation is still ill defined, the conditions that started fixed-particle stone formation in an individual patient can be obscure. Blood and urine analysis in such patients does not necessarily reveal the individual’s risk for recurrence as lifestyle may have changed over time. This is in fact what defines the so-called idiopathic stoneformers. For these patients, prevention of outgrowth of previously formed precipitates, papillary plaques, may be more relevant than prevention of new plaque formation. In contrast, a patient who has formed a stone in a relatively short time through the free-particle mechanism is more likely to show abnormal values in blood and urine that explain the starting event of stone formation. In these patients, measurement of such values provides useful information to guide preventive measures.

Abstract
OBJECTIVE To determine the extent to which validated techniques for behavior change have been infused in commercially available fluid consumption applications (apps). MATERIALS AND METHODS Coders evaluated behavior change techniques represented in online descriptions for 50 fluid consumption apps and the latest version of each app. RESULTS Apps incorporated a limited range of behavior change techniques (<20% of taxonomy). The number of techniques varied by operating system but not as a function of whether apps were free or paid. Limitations include the lack of experimental evidence establishing the efficacy of these apps. CONCLUSION Patients with urolithiasis can choose from many apps to support the recommended increase in fluid intake. Apps for iOS devices incorporate more behavior change techniques compared to apps for the Android operating system. Free apps are likely to expose patients to a similar number of techniques as paid apps. Physicians and patients should screen app descriptions for features to promote self-monitoring and provide feedback on discrepancies between behavior and a fluid consumption goal.
