As a result of the literature search in accordance with the inclusion criteria, from 319 articles, 13 publications were included in the final analysis (Fig. 2), of which two [9, 10], three [11,12,13], five [14,15,16,17,18], and one each [19,20,21], were devoted to determining the number of endourological patients who can be managed by telemedicine, endourological patient satisfaction, optimization the clinical decision making among patients with kidney and ureteric stones, the effectiveness of telemedicine in the management of patients with indications for PCNL, follow-up for patients with urolithiasis and describing financial effectiveness for the patients after BOO surgery, respectively. Median number of cases was 80 (range: 11–1008). Notably, the lowest patient number was used in the earliest study, done in 2005 [16]. Phone calls [9, 13, 14, 16,17,18, 20, 21], video calls [11, 19], both [10, 12], and online booking platform [15] were used in eight, two, two, and one study respectively. Urolithiasis and BPH cases were separately considered by 10 [10, 12,13,14,15,16,17,18,19,20] and one [21] study, whereas endourological nosology was not mentioned in two papers [9, 11]. Merits of telemedicine were indicated by all studies, whereas only six of 13 provided its disadvantages [10, 11, 13, 16,17,18] (Table 1).

Table 1 Details of the included studies, results and pros and cons of studies relating to telemedicine in endourologyTurcotte et al. surveyed all urologists practicing in the Quebec City region to get their views on the proportion of outpatient urological cases that might be fully handled using telemedicine outside of the COVID-19 pandemic [9]. Out of a total of 1679 appointments covering various urological fields, 152 were specifically associated with endourology, and the percentages for the different types of cases were 86.8% for complete, 9.9% for suboptimal, and 3.3% for incomplete management. Somani et al. examine the impact of a 7-week lockdown on all planned outpatient clinics and urgent operations [10]. Whenever feasible, all in-person appointments were converted to virtual telephone or video clinic appointments, except for patients who needed flexible cystoscopy and shockwave lithotripsy (SWL) treatments, who still attended in person. Out of a total of 193 patients with stone issues, 94 individuals (48.7%) were shifted to a telemedicine format.
Along with determining the number of endourology patients who can be safely assessed using telemedicine tools, it is important to ask them about their experience and identify factors that prevent telemedicine from being used in clinical practice. So, Glassman et al. conducted a study to evaluate patient satisfaction and determine if certain urological diagnoses are better suited for remote encounters [11]. The secondary aim was to assess patient satisfaction based on age and proximity to the clinic. The data indicates that the average satisfaction level among physicians was 4.9 (out of 5), while among patients it was 4.2. Similarly, Posid et al. conducted a sub-analysis of urologic telehealth patient satisfaction and kidney stone patients. 34.4% of patients utilized phone/audio, 45.0% used EPIC/MyChart video, and the rest used Doximity, UpDox, or other type of device [12]. Kidney stone patients (55.8%) were more likely to employ EPIC/MyChart video than other methods, and/or benign and oncology patients (p = 0.013). Overall, patients were very satisfied with their telemedicine consultation (M = 6.3/7, p < 0.001 vs. ‘neutral’), with kidney stone patients being somewhat more satisfied (p = 0.084). Heeno et al. evaluated patients' perception of their telephone consultation and their overall attitude toward the future implementation of telemedicine [13]. Out of the total number of patients, 230 individuals, which accounts for 85.0% of the sample, expressed satisfaction with their telephone consultation. Patient’s age, sex, and distance to the hospital were not associated with their satisfaction. However, the majority would prefer video consultations in the future if they had a choice in this.
Another crucial factor in assessing the utility of telemedicine is evaluating its immediate impact on monitoring and treating patients to improve the clinical decision-making process. Telemedicine for ureteric colic patients could eliminate the need for face-to-face review consultations, shorten appointment wait times, and better allocate clinic resources to other patients, according to Ong et al. [14]. The percentage of unplanned re-attendance was 3.2% with a sample size of 32. The reason for this was the repeated occurrence of painful colic in 27 cases, as well as miscommunication during the scheduling of the teleconsultation in 5 cases. The positive results of this telemedicine service have been consistently maintained over the past three years since its installation. The monthly recruitment rates ranged from 33.3% to 80.9%. The percentage of clinic consultations saved per month remained steady, ranging from 52.9% to 89.5%. The average time taken to evaluate phone consultations each month ranged from 26.5 to 35.8 days. An innovative telemedicine service for patients with ureteric colic has effectively decreased the frequency of follow-up appointments by 71.1% over three years, greatly exceeding the initial target of 25%. Furthermore, these results demonstrated the sustainability of the service, as seen by a small decline in the participation rate of 4.8%, indicating that patients found this service to be acceptable. This solution optimized resource allocation by saving an average of 238 clinic sessions each year, resulting in reduced waiting times for patients in need of conventional in-person consultations. Cullen et al. define the benefits of a virtual colic clinic for renal colic patients, such as simplified care and shorter wait times [15]. To assess the intervention's efficacy, the duration from referral to clinic review was compared to the proportion of patients seen within four weeks before and after the virtual clinic's deployment. The percentage of non-attendance fell from 18 to 5%. The average time between emergency department referral and urology clinic assessment was reduced from 7.5 to 3.5 weeks. 82% of patients were seen at the clinic within four weeks, up from 25% before. The typical period between referral and intervention ranged from 15 to 5 weeks, including SWL and primary ureteroscopy (URS).
One of the earliest studies examining the application of telemedicine dogma to both the entire urology and endourology fields was described by Johnston et al. who discovered a straightforward way to wirelessly transmit digital CT scans from patients with probable renal colic and one with renal trauma utilizing a Sony Clie 615C hand-held computer and a cellular phone with a modem [16]. Upper-tract stone presence/absence, stone position, estimated stone size, and obstruction indicators were diagnosed. Each patient had 5.9 ± 1.6 pictures, averaging 32.2 ± 5.2 kb (range 21–42 kb), delivered at 1 kb/sec. Interpretation properly recognized 80% of stone presence, 100% hydronephrosis, 80% perinephric stranding, and 1 ± 1 mm stone size. Connor et al. assessed a clinician-led virtual clinic (VC) treatment choice in patients with ureteric colic, with clinical, budgetary, and environmental effects [17]. Clinicians referred patients in real-time utilizing an electronic referral technique integrated into an electronic healthcare records platform (Cerner, North Kansas City, MO, USA). A professional nurse or consultant urologist called the patient on their phone or landline to do a VC consultation. This reduced the median VC decision time to 2 [1,2,3,4,5] days. In total, 347 patients (34.4%) were discharged from the VC (n = 164) or after another VC visit (n = 183). Four patients (0.40%) returned to the emergency room (ER) after a VC due to pain. Direct VC costs were £29,232 and face-to-face (FTF) clinic opportunity costs were £174,384. This saved £145,152 and an estimated 15,085 patient journey kilometers were also averted. Depending on the method of transport, travel avoidance produced 0.70–2.93 metric tons of CO2. Hughes et al. detailed their six-year experience with a nurse-led telephone-based virtual stone clinic (VSC) follow-up [18]. This approach was used to monitor patients with asymptomatic renal calculi or those at a high risk of recurring kidney stone disease (KSD). Before the consultation, the patient underwent interval imaging, which included a kidney, ureter, and bladder radiograph (KUB) XR to detect radio-opaque stones, as well as an ultrasound scan (USS) of the urinary tract to identify radiolucent stones. These tests were scheduled at the most convenient time and location for the patient. The VSC was conducted via telephone consultations facilitated by urology-specialized nurses. The duration of telephone consultations normally ranged from 5 to 10 min each. Patients were scheduled for face-to-face consultations if they experienced new symptoms, exhibited stone growth, or expressed a preference for in-person consultations. Over 6 years, the VSC has registered a total of 290 patients, who have collectively attended 468 appointments. By the conclusion of the research period, 132 patients, accounting for 45.6% of the total, were still enrolled in the Virtual Stone Clinic (VSC) and had scheduled follow-up appointments. 106 (36.6%) were discharged, and 47 (16.2%) either returned to in-person clinic visits or required additional treatment. Lastly, 5 (17.%) were hospitalized as emergency cases during the interim period.
To evaluate the effect of telemedicine among patients with an indication for the percutaneous nephrolithotomy (PCNL) treatment, Aydogdu et al. examined how additional video calls affected postoperative results, patient, and surgeon satisfaction in the patients who underwent PCNL [19]. The authors utilized Skype for videoconferencing. The average preoperative telerounding visit lasted 3.65 ± 0.59 (2–4) minutes. Telerounding visits on the first and second postoperative days averaged 3.80 ± 0.62 (2–5) and 2.9 ± 0.91 min. Surgeon satisfaction with telerounding was assessed with a visual analog scale (VAS) score of 91 ± 11.2 (60–100). Patients were satisfied, with 72.5% saying telerounding improved their treatment and 78% saying it should be a regular feature of hospital care. Additionally, 86% of patients said they could easily communicate with their doctor over telerounding, 85.5% said they would feel comfortable telerounding daily if they were hospitalized again, and 79.5% said they would rather use telerounding than see another doctor.
One key benefit of telemedicine is the capacity to monitor patients remotely, potentially resulting in enhanced adherence to physician instructions. Nevo et al. conducted a comparative analysis of the impact of telephone communication (PC) and in-person office consultations (OC) on urinary metabolic risk factors associated with stone formation [20]. The overall number of visits and the duration between the initial consultation and the final visit varied considerably between the groups. In comparison to patients who only underwent OC visits, those who underwent PC and OC had extended follow-up periods (51.7 vs 18.5 months, p < 0.0001) and more consultations (OC or PC, 5.4 vs 2.5, p < 0.0001). 86% of patients with OC alone had 1:3 return consultations, whereas 90% of patients with either OC or PC had 2:8 return consultations. A stone recurrence was observed in eight patients (38%) who had both OC and PC, compared to six (27%) patients who had only OC (p = 0.52). Notably, patients in the telemedicine group had substantially greater increases in urine volume than those in the OC group.
A study by Sarmah et al. dedicated specifically to the financial benefits obtained from performing telephone follow-up with patients following BOO surgery [21]. With VC, the total cost for the fifty telephone sessions was £2,392. Eleven patients who were not discharged promptly incurred supplementary fees totaling £3,674 for uroflowmetry and FTF visits. £6,066 was the entire cost of the new service. The projected cumulative cost savings to the health sector over a ten-month duration resulting from the utilization of virtual consultations amounted to £10,634. Three months after their surgery, patients were allocated a specific date and time for their appointments, and subsequently, they were contacted via telephone, contingent upon the realization of a post-operative trial without a catheter (TWOC). The patients were contacted via telephone to complete the IPSS questionnaire; the IPSS and Quality of Life (QoL) scores were calculated based on their responses. Primary care was notified of patients whose IPSS scores fell below eight.
