Abstract
INTRODUCTION Symptomatic hydronephrosis associated with muscle invasive bladder cancer (MIBC) necessitates percutaneous nephrostomy (PCN) insertion before neoadjuvant chemotherapy (NAC). This study assesses the impact of PCN presence on standard intended NAC quality, its related complications and outcome after radical cystectomy (RC). MATERIALS AND METHODS The study comprises a retrospective, multicenter cohort of 193 consecutive RCs performed between 2016 and 2019. Eighty (42%) of these patients received NAC and were divided in 2 comparison groups by presence (n = 26; 33%) or absence (n = 54; 67%) of PCN. Endpoints included completion of adequate NAC treatment (cisplatin-based chemotherapy for at least 4 courses), complications during NAC, post-RC complications and hospital stay. RESULTS Overall, patients with PCN (45/193; 23%) featured a higher referral rate to NAC (58% vs. 36%, P = .01), worse glomerular filtration rates (P < .001) and more adverse events (P = .04), in comparison to non-PCN patients. In the NAC cohort, PCN patients had less adequate treatment rates (54% vs. 85%, P = .005), and more infections (35% vs, 7%; P = .008) and hospitalizations (58% vs. 13%; P < .001) during chemotherapy. Post-RC outcome was similar for both comparison groups. PCN was an independent risk factor for inadequate NAC (OR = 3.9, P = .04), and infections (OR = 11.3, P = .01) and hospitalizations (OR = 7.5, P = .004) during NAC. CONCLUSIONS PCN in MIBC patients is a significant risk factor for inadequate NAC and adverse events during treatment. This finding may quire the rationale of NAC, potentially leading to consideration of NAC avoidance and upfront RC in PCN patients. Further survival studies with long follow-up are needed for elucidating this issue.

Results of Temporary Drainage of Poorly Functioning Kidneys With Ureteropelvic Junction Obstruction: Does the Histology of Persistent Poor Functioning Kidneys Indicate an Increased Risk of Hypertension? Urology 2024; 184:189-194. [PMID: 37923087 DOI: 10.1016/j.urology.2023.10.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [What about the content of this article?

Abstract
OBJECTIVE To review our experience with managing poorly functioning kidneys with ureteropelvic junction obstruction (PFK-UPJO) with differential renal function (DRF) <10% by a trial of temporary drainage, as the management of such kidneys is controversial. We also studied the histopathologic changes in the nephrectomy specimens of persistent PFK-UPJO, as tubulointerstitial damage may predispose to hypertension. METHODS A retrospective review of cases undergoing treatment for unilateral UPJO over 5-year period in 2 centers was conducted. In PFK-UPJO, 4-6 weeks trial of drainage with double J stent or percutaneous nephrostomy was employed. Those kidneys that improved DRF to >10% underwent pyeloplasty, while persistent PFK underwent nephrectomy; the specimens were studied for interstitial fibrosis/tubular atrophy (IF/TA), arterial lesions, and arteriole lesions. RESULTS Of 402 patients with unilateral UPJO that underwent surgical management, 17 (4.1%) had PFK-UPJO. After 4-6 weeks trial of drainage, 6 kidneys (35.2%) with improved DRF underwent pyeloplasty, while 11 kidneys with persistent PFK underwent nephrectomy; significant IF/TA, arterial, and arteriolar changes were noted in 9 (82%), 9 (82%), and 4 (36%) kidneys, respectively, including 7 kidneys in normotensive children. Two (11.7%) children had hypertension at presentation; 1 child remains hypertensive even after nephrectomy. CONCLUSION In PFK-UPJO, trial of temporary drainage seems appropriate to decide plan of management; 35% of such kidneys improved function after drainage. Most persistent PFK demonstrated severe and irreversible histologic changes that may predispose to hypertension if they are preserved, and we suggest that such kidneys may be removed. Long-term follow-up of all preserved PFK-UPJO is strongly recommended.

Abstract
Lay summary
Malignant ureteric obstruction (MUO) is frequently encountered in patients with advanced cancers. In the largest study to date, assessing 852 patients from across Scotland, the authors demonstrated the presence of MUO as a marker of advanced disease across cancer types, with poor survival for many patients, even with intervention. There is uncertainty in optimal management of this condition, with marked differences in management between hospitals. Treatment to relieve the obstruction does not guarantee either improvement in kidney function or progression to further oncological treatment. The authors have developed a prognostic tool to estimate outcomes after intervention for MUO, and advocate its use for clinicians along with other data presented for patient counselling.

Abstract
OBJECTIVE To evaluate peri-operative outcomes in patients on chronic aspirin therapy undergoing percutaneous nephrolithotomy (PCNL), with and without discontinuation of aspirin. Anti-coagulation and anti-platelet therapy are contraindications for PCNL per American Urological Association guidelines due to bleeding risk. However, there is potentially increased cardiovascular risk with peri-procedural aspirin withdrawal. METHODS Patients on chronic aspirin undergoing PCNL between January 2014 and May 2019 were retrospectively reviewed and stratified by continued or discontinued aspirin >5 days preoperatively. Hematologic complications, transfusions, and thrombotic complications were assessed with logistic regression model. RESULTS Three hundred twenty-five patients on chronic aspirin therapy underwent PCNL-85 continued and 240 discontinued aspirin. There were no significant differences in hemoglobin change, estimated blood loss, transfusions, creatinine change, thrombotic complications, 30-days re-admissions, complications, or 30-day emergency department visits. Patients who continued aspirin had longer length of stay (1.6 vs 1.9 days, P = .03). American Society of Anesthesiologists (ASA) score of 3 (OR 3.2, P = .02, 95% confidence intervals (CI) [1.2-8.4]), ASA score of 4 (OR 4.0, P = .02, 95% CI [1.2-13.1]), Black race, and previous smoking (OR 2.1, P = .02, 95% CI [1.1-3.9]) was associated with continued aspirin. Body mass index ≥30 was associated with aspirin discontinuation (OR 0.9, P = .004, 95% CI [0.9-1.0]). Increased postoperative hematologic complications were associated with additional anticoagulation medication (OR 2.9, P = .04, 95% CI [1.0-4.4]). CONCLUSION Continued aspirin use did not increase in postoperative complications in patients undergoing PCNL. Patients who are on additional anticoagulation medication are at risk of hematologic complications.

Abstract
PURPOSE There is increasing interest in the use of ultrasound for endoscopic and percutaneous procedures. Access can be achieved without radiation exposure under ultrasound guidance. Our aim was to develop a porcine-based training model for ultrasound-guided percutaneous renal access that could also be personalized to a specific patient. MATERIALS AND METHODS The Institutional Animal Care and Use Committee of Severance Hospital approved the study protocol. An anesthetized pig was placed in the dorsal lithotomy position. For the nephrostomy puncture, a Chiba biopsy needle with an echo tip was used under ultrasound guidance. Eight residents and three consultants in urology participated. Puncture time was defined as the nephrostomy time to confirm the flow of irrigation via the needle. After training, satisfaction survey results for clinical usability and procedural difficulty were evaluated. RESULTS The 5-point Likert scale satisfaction survey for clinical usability and procedural difficulty found mean results of 4.64 and 4.09 points, respectively. There were no differences between residents and consultants for either variable. For all participants combined, there was a significant difference for nephrostomy time between the first and second trials (278.8±70.6 s vs. 244.5±47.0 s; p=0.007). The between-trial difference was greater for residents (291.5±71.2 s vs. 259.1±41.9 s; p=0.039). The difference for the consultant was not significant (245.0±69.4 s vs. 205.7±42.5 s; p=0.250). CONCLUSIONS We developed a porcine-based ultrasound-guided nephrostomy puncture training model. Satisfaction survey results indicated high clinical usability and procedural difficulty. For nephrostomy time, the model was more effective for urology residents than for consultants.

Abstract
INTRODUCTION Percutaneous nephrostomy tubes (PNT), which are used in some cancer hospitals, are associated with an increase in urinary tract infections (UTI). OBJECTIVE To determine the impact of a standardized care program on the incidence of UTIs requiring hospitalization (UTI-RH). MATERIAL AND METHODS Retrospective study that included patients with a first PNT inserted. The incidence, relative risk (RR), costs and outcomes of patients with UTI-RH were compared during the period before (P0) vs. after the intervention (P1). RESULTS 113 PNTs were inserted during P0, and 74 at P1. During P0, 61 patients (53.9%) experienced 64 UTI-RH events in 22,557 PNT days. At P1, four patients (5.4%) had a UTI-RH in 6,548 PNT days (IRR: 0.21, 95% CI: 0.05-0.57). The RR was 0.09 (95% CI: 0.03-0.25). Monthly cost per day/bed was USD 3,823 at P0 and USD 1,076 at P1, and for antibiotics, it was USD 790 at P0 and USD 123.5 at P1. CONCLUSIONS This study highlights the importance of a standardized care program for permanent percutaneous devices, since this reduces antibiotic use, hospitalization, and the cost of care.

Abstract
PURPOSE To compare the effects of different preoperative antibiotic prophylaxis (ABP) regimens on the incidence of sepsis after percutaneous nephrolithotomy (PCNL) in patients with negative urine culture. METHODS A single-center, randomized controlled trial (June 2022-December 2023) included 120 patients with negative preoperative urine cultures for upper urinary tract stones who underwent PCNL (chictr.org.cn; ChiCTR2200059047). The experimental group and the control group were respectively given different levofloxacin-based preoperative ABP regimes, including 3 days before surgery and no ABP before surgery. Both groups were given a dose of antibiotics before the operation. The primary outcome was differences in the incidence of postoperative sepsis. RESULTS A total of 120 subjects were included, including 60 patients in the experimental group and 60 patients in the control group. The baseline characteristics of the two groups were comparable and intraoperative characteristics also did not differ. The sepsis rate was not statistically different between the experimental and control groups (13.3% vs.13.3%, P = 1.0). A multivariate logistic regression analysis revealed that body mass index (BMI) (OR = 1.3; 95% CI = 1.1-1.6; P = 0.003) and operating time (OR = 1.1; 95% CI = 1.0-1.1; P = 0.012) were independent risk factors of sepsis. CONCLUSION Our study showed that prophylactic antibiotic administration for 3 days before surgery did not reduce the incidence of postoperative sepsis in patients with negative urine cultures undergoing PCNL. For this subset of patients, we recommend that a single dose of antibiotics be given prior to the commencement of surgery seems adequate.

Abstract
Introduction: Percutaneous nephrolithotomy (PCNL) is the recommended treatment for 2-4-cm renal stones. Minimally invasive PCNL (MPCNL) with ≤22F sheath was frequently used instead of standard PCNL. MPCNL uses pressurized irrigation to flush out stone fragments through a conventional nephrostomy sheath (cNS), which may result in higher intrarenal pressure (IRP) and longer operating time. The novel vacuum-assisted nephrostomy sheath (vaNS) was developed to mitigate higher IRP and to facilitate stone removal. It might improve the performance of MPCNL. This prospective and randomized trial compares these two sheaths. Materials and Methods: In total, 120 patients with 2-4-cm renal stones were accrued in six tertiary medical centers with equal numbers in 2021. In total, 120 patients underwent mPCNL, 60 using 18F cNS and 60 using 18F vaNS, in a prospective and randomized assignment. The primary outcome measurement is decrease in IRP. The secondary outcome is efficacy in stone retrieval. Results: The IRP was lower with vaNS than with cNS: mean IRP during lithotripsy was 12.0 ± 2.7 mm Hg with vaNS vs 20.4 ± 6.0 mm Hg with cNS, p = 0.000. IRP duration ≥30 mm Hg was shorter with vaNS than with cNS (6.7 ± 7.4 seconds vs 113.4 ± 222.7 seconds, p = 0.001). vaNS has shorter stone removal time (26.9 ± 14.3 minutes vs 35.7 ± 11.8 minutes, p = 0.000). Stone extraction rate was higher (166.4 ± 88.1 mm3/min vs 90.4 ± 31.7 mm3/min, p = 0.000). Stone grasper usage was less (1.4 ± 2.6 vs 11.9 ± 9.7, p = 0.000). vaNS maintained the safety profile. Blood loss, creatinine changes, perioperative complications, and hospital stays were the same in both groups, all p > 0.05. Conclusion: MPCNL for stones 2-4 cm using vaNS has shorter stone removal time, higher stone extraction rate, and less use of stone extractor. vaNS is superior to cNS at reducing IRP and is associated with improved stone free rates at 3 days but not at 30 days postoperatively. The trial was registered with Chinese Clinical Trial Registry (ClinicalTrials.gov, NCT ChiCTR2000039681).

Abstract
OBJECTIVE Patients with ureteral calculi and systemic inflammatory response syndrome (SIRS) often require emergency drainage, and percutaneous nephrostomy (PCN) and retrograde ureteral stent insertion (RUSI) are the most commonly used methods. Our study aimed to identify the best choice (PCN or RUSI) for these patients and to examine the risk factors for progression to urosepsis after decompression. METHODS A prospective, randomized clinical study was performed at our hospital from March 2017 to March 2022. Patients with ureteral stones and SIRS were enrolled and randomized to the PCN or RUSI group. Demographic information, clinical features and examination results were collected. RESULTS Patients (n = 150) with ureteral stones and SIRS were enrolled into our study, with 78 (52%) patients in the PCN group and 72 (48%) patients in the RUSI group. Demographic information was not significantly different between the groups. The final treatment of calculi was significantly different between the two groups (p < .001). After emergency decompression, urosepsis developed in 28 patients. Patients with urosepsis had a higher procalcitonin (p = .012) and blood culture positivity rate (p < .001) and more pyogenic fluids during primary drainage (p < .001) than patients without urosepsis. CONCLUSION PCN and RUSI were effective methods of emergency decompression in patients with ureteral stone and SIRS. Patients with pyonephrosis and a higher PCT should be carefully treated to prevent the progression to urosepsis after decompression.Key messageIn this study, we evaluate the best choice (PCN or RUSI) for patients who have ureteral stones and SIRS and to examine the risk factors for progression to urosepsis after decompression. This study found that PCN and RUSI were effective methods of emergency decompression. Pyonephrosis and higher PCT were risk factors for patients to develop to urosepsis after decompression.

Abstract
INTRODUCTION Mini PCNL has gained popularity in adult patients due to reduction in the complication rate with comparable stone free rate. There is paucity of level 1 evidence regarding the benefit of mini PCNL in the pediatric group. OBJECTIVE We performed a randomised study to compare mini PCNL (mPCNL) with standard PCNL (sPCNL) for the management of renal calculi in patients less than 18 years of age in terms of safety, efficacy, and stone-free rate (SFR). MATERIALS AND METHODS A randomised controlled trial was performed on 50 children who underwent PCNL from June 2015 to March 2021, who were divided into two groups. Group I had 25 patients managed with mPCNL (sheath size 16.5 Fr) and Group II had 25 patients who underwent sPCNL (sheath size 26 Fr). Primary outcomes including stone free rates (SFR) and hemoglobin drop and secondary outcomes like operative time, complications, pain score, need of analgesia, incidence of nephrostomy site leak, hospital stay in days were compared between the two groups. RESULTS The mean age of patients in groups I and II was 9.4 ± 2.6 and 10.4 ± 2.26 years, respectively (p = 0.15). The mean stone sizes in both groups I and II were 18.6 ± 2.56 and 20.2 ± 3.58 mm, respectively (p > 0.05). The stone free rate for group I was 88% and for group II, 92% (p = 0.64). The average drop in hemoglobin was higher in group II compared to group I (1.1 ± 0.31 g/dl and 1.7 ± 0.23 g/dl respectively; p < 0.0001), however the mean blood transfusion rate was not significantly different in both groups. The operating time was shorter in group II compared to group I (p-value - 0.0030). The pain scores were lesser for the group I. Grade I complications were higher in group II as compared to group I (p-0.047); however, grade II complications were comparable in both groups. The mean hospital stay was not significantly different in both groups. DISCUSSION This study confirms the role of mini PCNL in pediatric patients with renal stones. The stone clearance rate of mini PCNL is equivalent to standard PCNL, with lesser blood loss and postoperative complications, however with longer operative time during mPCNL. The small number of the participants in both arms is a limitation of this study and may also reflect fewer children with urolithiasis being treated surgically even in a tertiary care referral centre. CONCLUSIONS Mini-PCNL offers equivalent stone free outcome with lower complications rate compared to the standard PCNL for all types of renal stones.

Abstract
OBJECTIVE To assess the stone-free rate (SFR) subsequent to percutaneous nephrolithotomy (PCNL) in patients with anatomically anomalous kidneys. STUDY DESIGN Cross-sectional study. Place and Duration of the Study: Department of Urology, Sindh Institute of Urology and Transplantation Karachi, from 23 July 2020 till 30 October 2021. METHODOLOGY Sixty-five patients of renal stone disease with abnormal kidneys, aged 18-60 years of both genders were enrolled in this cross-sectional study. Demographic information like age, gender, stone size, duration of disease, and type of abnormality were noted. After PCNL, stone-free status was determined after 2 weeks of the procedure by performing ultrasound KUB. RESULTS A total of 65 patients were included in this study with mean age of 36.37 ± 12.86 years [Range: 18-60]. There were 76.9% of males and 23.1% of females. Regarding anatomical malformation, 46.2% were malrotated kidneys, 16.9% were horseshoe kidneys, 16.9% were partial Duplex system, 9.2% had bifid pelvis. Median duration of the disease was 12 (IQR=10). Forty-one patients (63.1%) had single and 24 (36.9%) had multiple number of stones with average size of 3.26 ± 1.14 cm. SFR after PCNL in patients with abnormal kidneys was 70.77% (46/65) while 29.23% (19/65) were observed with residual fragments. Out of 19 cases with residual fragments, 10 (53.2%) had stone size <1 cm and 9 (47.4%) had stone of 1 to 3 cm. Sixteen out of 19 patients with residual stones were treated with ESWL (most required: one session), and re-do PCNL was performed in three cases. CONCLUSION PCNL is an effective and safe operation in anatomically anomalous kidneys. For satisfactory outcomes, it requires extreme care and exceptional surgical skill.

Abstract
OBJECTIVE To develop a reporting checklist that serves to improve and standardise reporting in studies pertaining to paediatric percutaneous nephrolithotomy (PCNL). METHODS Based on findings from systematic review of literature, a draft list of items was formulated. By process of review and revisions, a finalised version was established and consensus achieved. RESULTS The finalised version of the checklist covers four main sections, which include the following areas: study details, pre-operative, operative and post-operative information. There are 18 further sub-items. Recommendations deemed to be of high importance to include are highlighted in bold. CONCLUSION This practical tool can aid clinicians and researchers when undertaking and reviewing studies on paediatric PCNL. This is highly relevant given the current heterogeneity that exists as well as debate in best practice patterns.

Abstract
Purpose: Retrograde intrarenal surgery (RIRS) has been accepted as a first-line therapeutic option for kidney stones <2 cm. Renal mobility might be a challenging situation for the surgeon targeting the laser, thereby limiting the renal mobility during surgery might affect the surgical success. The main objective of the present trial was to evaluate the effect of two different ventilation modes on the efficacy and safety of RIRS performed under general anesthesia. Materials and Methods: The patients undergoing RIRS from January 2023 to April 2023 were prospectively enrolled in the trial. In the standard ventilation (SV) mode, the tidal volume was 8 to 10 mL/kg with respirations per minute being 10-15, whereas in the high ventilation (HV) mode the tidal volume was reduced to 6 to 8 mL/kg with the frequency being increased to 15 to 18 respirations/minute. For the purposes of the trial and the randomization, the anesthesiologist was informed about the ventilation mode used, whereas the surgeon was blinded. The surgical success rates and the observed complications were compared between SV and HV modes. Results: A total of 144 patients were enrolled with the mean age 48.78 ± 14.16 years. The mean duration of operation was 62.9 ± 26.3 minutes in the SV group, whereas it was 58.4 ± 20.1 minutes in the HV group (p = 0.031). Fragmentation rate of the stones per minute was higher in the HV group with the difference being statistically significant (p = 0.003). In the preoperative period, while hematuria was seen at higher rates in the HV group, the difference was not statistically significant (p = 0.671). Stone-free rates (Grades A-B-C) and the rates of postoperative complications were comparable between the groups (p = 0.605 and p = 0.676, respectively). Conclusion: Using HV mode during the RIRS decreased the operative time and provided the surgeon with the ability to target the laser more effectively. Surgeons might prefer using the HV mode during RIRS in a mobile kidney to reduce their operative time and perform comfortable surgery. ClinicalTrials.gov: The trial is registered at ClinicalTrials.gov with the registration number of NCT05792670.

Abstract
INTRODUCTION Calyceal diverticulum (CD) is the outpouching of a calyx into the renal parenchyma, connected by an infundibulum. Often associated with recurrent stones, common surgical options include percutaneous nephrolithotomy (PCNL) or retrograde intrarenal surgery (RIRS). We aim to present the real-world practises and outcomes comparing both approaches and the technical choices made. MATERIALS AND METHODS Retrospective data including 313 patients from 11 countries were evaluated. One hundred and twenty-seven underwent mini-PCNL and one hundred and eighty-six underwent RIRS. Patient demographics, perioperative parameters, and outcomes were analysed using either T test or Mann-Whitney U test. Categorical data between groups were analysed using the Chi-squared test. Propensity score matching (PSM) was performed matching for baseline characteristics. Subgroup analyses for anomalous/malrotated kidneys and difficult diverticulum access were performed. RESULTS After PSM, 123 patients in each arm were included, with similar outcomes for stone-free rate (SFR) and complications (p < 0.001). Hospitalisation was significantly longer in PCNL. Re-intervention rate for residual fragments (any fragment > 4 mm) was similar. RIRS was the preferred re-intervention for both groups. Intraoperative bleeding was significantly higher in PCNL (p < 0.032) but none required transfusion. Two patients with malrotated anatomy in RIRS group required transfusion. Lower pole presented most difficult access for both groups, and SFR was significantly higher in difficult CD accessed by RIRS (p < 0.031). Laser infundibulotomy was preferred for improving diverticular access in both. Fulguration post-intervention was not practised. CONCLUSION The crux lies in identification of the opening and safe access. Urologists may consider a step-up personalised approach with a view of endoscopic combined approach where required.

Abstract
Background: Percutaneous nephrostomy (PCN) is a commonly performed procedure by interventional radiology and urology to treat urinary obstruction. In this procedure, a catheter is percutaneously placed into the renal pelvis for urinary diversion or hemorrhagic cystitis. Material type, catheter size, and catheter shape (anti-dislodgement feature) ultimately contribute to the inherent traits of longevity in drainage catheter device. Reviewing the relative strengths or weaknesses of products in the existing clinical market may help clinicians critically appraise the devices they use with evidence-based findings from this review. Furthermore, a deeper understanding of the relative strengths and weaknesses of existing devices may help inform the next generation of drainage catheter devices to prolong the interval between exchanges without detriment to patient safety. Methods: The following electronic databases will be queried: PubMed, Web of Science, Cochrane from their inception to January 2023 to identify randomized controlled trials (RCTs) and cohort studies to investigate the differences that our interventions of catheter material, size, and dislodgement mechanism will have on the exchange interval (standard of care 90 days vs. 60 days vs. 45 days vs. 30 days). The primary outcomes will be the drainage catheter exchange frequency. Ethics and dissemination: We aim to share our findings through high-impact peer reviewed journals. As drainage catheters and minimally invasive interventional radiology procedures become more popular, it is important for healthcare providers taking case of these populations to understand which variables might optimize patient care and minimize emergent exchanges. Data will be made available to readers. Registration: PROSPERO ( CRD42023432788, 16 June 2023).

Abstract
INTRODUCTION The goal of this study was to evaluate the efficacy and safety of needle-perc-assisted endoscopic surgery (NAES) in the treatment of staghorn renal stones via a single-center prospective randomized controlled study. METHODS A total of 219 patients with partial or complete staghorn renal stones were prospectively randomized into two groups between January 2020 and April 2022. In group A (n = 112), patients were treated with traditional standard access, multiple if necessary, and in group B (n = 107), only one standard access was made, and needle-perc was assisted to remove the residual stones in the same stage. All procedures were guided under ultrasound totally. Stone size, operating time, blood loss, pain score, complications, and other related characteristics were monitored and analyzed. RESULTS Procedures were successful in all patients. The baseline characters were similar between the groups. The mean stone size was comparable (4.5 ± 1.4 vs. 4.7 ± 1.7, p = 0.35). The 1-month stone-free status was achieved in 85 patients (75.9%) in group A and 80 (74.8%) patients in group B (p = 0.72). The operation time was shorter in group A than B (75.1 ± 28.1 min vs. 97.2 ± 20.4 min, p = 0.02). A less blood loss (p = 0.01), shorter hospital stay (p = 0.04), lower pain score (p = 0.04), and lower severe complication rates (p = 0.03) were observed in group B. CONCLUSION NAES reveals better postoperative recurrence compared with traditional multiple tracts method for treating staghorn renal stones. The stone-free rate was comparable between the two groups.

Abstract
BACKGROUND The advantages and disadvantages of retrograde intrarenal surgery (RIRS) and minimally invasive percutaneous nephrolithotomy (mPCNL) for treatment of upper urinary tract calculi have not been conclusively determined. METHODS In this meta-analysis, We comprehensively evaluated the performance of the two surgical approaches in treatment of upper urinary calculi. We searched the Pubmed, Embase, Cochrane and Web of science databases for randomized controlled trial (RCT) articles on RIRS and mPCNL upto December 2022. Data were extracted by two independent reviewers and subjected to the meta-analysis using the Stata 15.1 software (StataSE, USA). RESULTS A total of 18 eligible RCTs involving 1733 patients were included in this study. The meta-analysis revealed that mPCNL of 1-2 cm or 2-3 cm stones had a higher stone clearance rate (RR:1.08, 95%CI (1.03, 1.14), p = 0.002) and shorter operation time (WMD : -10.85 min, 95%CI (-16.76, -4.94), p<0.001). However, it was associated with more hospital stay time (WMD :1.01 day, 95%CI(0.53, 1.5), p<0.001), hemoglobin drops (WMD :0.27 g/dl, 95%CI (0.14, 0.41), p<0.001), blood transfusion rate (RR:5.04, 95%CI(1.62, 15.65), p = 0.005), pain visual analogue score (WMD:0.75, 95%CI (0.04, 1.46), p = 0.037), hospital costs (SMD :-0.97, 95%CI (-1.19, -0.76), p<0.001) and major complications (RR:1.89, 95%CI(1.01, 3.53), p = 0.045). CONCLUSION Therefore, in terms of surgical effects and operation time, mPCNL is superior to RIRS, but is inferior with regards to other perioperative parameters. These factors should be fully considered in clinical decision making.

Abstract
OBJECTIVE The percutaneous nephrolithotomy (PCNL) in Horseshoe kidneys (HSK) is usually performed in the prone position, allowing entry through the upper pole and providing good access to the collecting system. However, in patients with normal kidney anatomy, the supine position is reliable and safe in most cases, but it is unknown whether the supine position is adequate in patients with HSK. The purpose of this study was to describe the results of PCNL in HSK in three different surgical institutions and to evaluate the impact of supine position during surgery, comparing pre-operative and post-operative data, complications, and stone status after surgery. MATERIAL AND METHODS Between 2017 and 2022, a total of 10 patients underwent percutaneous renal surgery for stone disease in HSK. All patients were evaluated pre- and post- operatively with non-contrast CT. we evaluated patients (age and gender), stones characteristics (size, number, side, site and density ), and outcomes. The change in haemoglobin, hematocrit, creatinine and eGFr were assessed between the most recent preoperative period and the first postoperative day. Procedure success was defined as stone-free or presence of ≤4 mm fragments (Clinically Insignificant residual Fragments - CIrF). Complications were registered and classified according to Clavien-dindo Grading System, during the 30 - day postoperative period and Clavien scores ≥ 3 were considered as major complications. Statistical analysis was performed using "r 4.2.1" software, with a 5% significance level. we also compared pre-operative and post-operative data using "wilcoxon signedrank test". RESULTS No statistical difference was observed between preoperative and post-operative renal function data. At one post operative day CT scan, an overall success rate of 100% was registered. 9/10 patients were completely free from urolithiasis (stone-free rate: 90%), while 1/10 patients had ≤4 mm residual stone fragments (CIrF rate: 10%). No cases of intraoperative complications were registered. Post-operative complications were reported in 1/10 patients. A patient developed urosepsis (defined as SIrS with clinical signs of bacterial infections involving urogenital organs - Clavien-dindo Grade II) after procedure, and was treated with intravenous antibiotic therapy successfully. Conclusions: This study shows that in patients with HSK mini- PCNL in supine position allows to achieve good stone free rate with a very low morbidity. According to our series, the described technique for PCNL in HSK should be an option. Nevertheless these results must be confirmed by further studies.

Abstract
OBJECTIVE Develop a mesh model to define a new "index amount of stone" to evaluate calculus and predict lithotripsy time. METHODS The stones were divided into target units with diameter of 5 mm by the mesh from x, y and z directions, and the cross-sectional areas between units were calculated as amount of stone as a new index to evaluate calculus. Design a prospective study with 112 cases of percutaneous nephrolithotomy to verify the reliability of this index, and to compare the accuracy of the quantity, volume and maximum diameter of stones in predicting the time of lithotripsy. RESULTS Amount of stone (Q) is reliable. The lithotripsy time was significantly correlated with the amount of stone, volume and maximum diameter of the stone (p < 0.01). The three regression equations were valid. The linear fit in the amount group was larger than that in the volume group, and further larger than that in the maximum diameter group, with R2 values of 0.716, 0.661 and 0.471, respectively. CONCLUSIONS It is more accurate and convenient to use amount of stone to evaluate calculus, which can be used to predict the lithotripsy time.

Abstract
PURPOSE To report the result of percutaneous nephrolithotripsy (PCNL) via standard nephrostomy tract in a single training institution. The perioperative complications in relation to the comorbid state are particularly assessed. PATIENTS AND METHODS A prospective interventional study between January 2019 to November 2022, included 210 patients scheduled for PCNL. The average age was 40.3 ± 11.8 years (range 18- 67 years). Patients were categorized into two groups. The first group comprised 146 cases (69 .5%) with no associated co-morbidities while the second group 64 (30.5%) had co-morbidities such as obesity in 4 cases (1.9%), hypertension (HTN) in 24 cases (11.4%) cases, diabetes mellitus (DM) in 17 (8.1%) cases, history of recurrent stone surgery in 11 (5.2%) cases and more than one in 8 cases (3.8%). Co-morbidities, stone burden, location of stone, time of surgery, stay in the hospital, further operations, and negative events were among the reported data. Complications and the stone-free rate were the main outcome indicators. RESULTS Intraoperative complications were reported in 40 (18.8%) patients (18 group 1 and 22 group 2) during PCNL. Bleeding occurred in 22 (10.5%) patients (9 group 1 and 13 group 2), blood transfusions were needed in 4 (1.9%) (2 group 1 and 2 group 2), extravasation was observed in 11 patients (5.2%) (6 group 1 and 5 group 2) and cardiac arrhythmia in 3 (1.4%) (1 group 1 and 2 group 2) patients. Postoperative complications occurred in 61 patients (29%) (24 group 1 and 37 group 2) in the form of fever in 10 patients (4.8 %) (3 group 1 and 7 group 2) and prolonged leakage in 50 patients (23.8%) (21 group 1 and 29 group 2). One patient of group 2 died from postoperative sepsis. Extravasation and postoperative leakage were higher in diabetic patients than in non-diabetics. Stonefree rate was 60.5% (127 of 210). Clinically significant residual fragments (CSRFs) found in 70 cases (33.3%) (33 group 1 and 37 group 2). In 13 cases (6.2%) (5 group 1 and 8 group 2), clinically insignificant residual fragments (CIRFs) were found. In 8 (3 group 1 and 5 group 2) of the 13 cases, spontaneous stone passage was observed within 4-6 weeks of surgery. Residual stones in three cases (1 group 1 and 2 group 2) were asymptomatic and 4 mm or less, whereas stones increased in two cases of group 2. Among all factors studied, stone burden was significantly correlated to both intraoperative and postoperative complications. The occurrence of postoperative fever increased with large stone burden. CONCLUSIONS PCNL is a therapeutic modality that is effective, feasible, and safe for a wide range of patients with concurrent medical issues. A steep curve is required to reduce intraoperative and postoperative complications.

Abstract
PURPOSE OF REVIEW Miniaturized PCNL (mi-PCNL) for stone disease is performed under a general anesthesia. However, the role of loco-regional anesthesia in mi-PCNL and its outcomes are not well defined yet. Here, we review the outcomes and complications of loco-regional anesthesia for mi-PCNL. A Cochrane-style review was performed in accordance with the preferred reporting items for systematic reviews to evaluate the outcomes of loco-reginal anesthesia for URS in stone disease, including all English language articles from January 1980 and October 2021. RECENT FINDINGS Ten studies with a total of 1663 patients underwent mi-PCNL under loco-regional anesthesia. The stone-free rate (SFR) for mi-PCNL under neuro-axial anesthesia ranged between 88.3 and 93.6%, while it ranged between 85.7 and 93.3% for mi-PCNL under local anesthesia (LA). The conversion rate to another anesthesia modality was 0.5%. The complications ranged widely between 3.3 and 85.7%. The majority were Grade I-II complications and none of the patients had grade V complications. Our review shows that mi-PCNL under loco-regional anesthesia is feasible with good SFR and a low risk of major complications. The conversion to general anesthesia is needed in a small minority, with the procedure itself being well tolerated and a big step towards establishing an ambulatory pathway for these patients.

Abstract
PURPOSE OF REVIEW To systematically review the evolution of techniques, technology, clinical utility, limitations and possible future applications of endoscopic combined intrarenal surgery (ECIRS) for ureteral and kidney stones. RECENT FINDINGS The literature search was performed on 18th January 2023 using PubMed, EMBASE and Scopus. 35 studies were included. Among them, six were reviews. Since its introduction in 2008, ECIRS has evolved and improved. ECIRS can be performed in different patient position, such as modified supine Valdivia position by Galdakao, prone position with split-leg and supine position with good outcomes. Instrument miniaturization has also been introduced in ECIRS making it doable in an ambulatory setting. ECIRS showed shorter operative time, lower complication rate, and retreatment compared with conventional PCNL. Operative outcomes of mini-ECIRS are better than mini-PCNL alone. ECIRS also showed good outcomes in impacted upper ureteric stones. Recently, some studies have explored the robotic-assisted kidney puncture in ECIRS that avoided multitrack surgery, especially in anomalous kidney and staghorn stones. SUMMARY ECIRS is ready for primetime in endourology and can be considered the next gold-standard for a personalized stone approach in complex kidney stones.

Abstract
Introduction and Objectives: Mini-percutaneous nephrolithotomy (PCNL) has gained popularity over the last decade due to its stone-free rate comparable to traditional PCNL but with decreased risk of complications. While the data on mini-PCNL has been favorable thus far, no study today has evaluated outcomes in obese patients. Methods: All patients undergoing mini-PCNL at our institution since we began its use in 2019 were included in this study. Mini-PCNL was defined as access sheath ≤22F in size. An obese group with body mass index (BMI) ≥30 was compared to a nonobese group with BMI <30. A patient was considered relatively stone free if residual fragments were <4 mm on follow-up CT with ≤3 mm cuts. Fisher exact test was used to compare dichotomous differences between variables, and t-test to compare continuous variables. Results: We identified 67 patients who underwent mini-PCNL during the study period with 33 patients in the obese group. Median BMI in the obese group was 36.4 kg/m2 compared to 25.05 kg/m2 in nonobese. There were no blood transfusions in either group during the study period. There was no statistical difference between the obese vs nonobese group for age, access sheath size, change in hemoglobin, same day discharge, percent relatively stone free, emergency department visit within 30 days, and median largest single stone diameter. There was a significant difference in the sum of all treated stone diameter in the obese group (median 15 mm) vs nonobese (median 18 mm, p = 0.02) (Table 1). Conclusion: Mini-PCNL appears to be equally safe and effective in obese and nonobese patients alike. While there was a statistically significantly higher amount of overall stone burden in the nonobese groups, the overall difference is not clinically significant. Further research is needed to validate our experience.

Abstract
Calculus anuria is a catastrophic condition with dire consequences if not treated promptly. The purpose of this study was to identify factors which influence the short-term outcome of patients with calculus anuria. A retrospective analysis was conducted from January 2016 to December 2021, in children up to the age of 18 years, who presented with calculus anuria and required emergency decompression at Sindh Institute of Urology and Transplantation, Pakistan. One hundred and twenty-five children were included. Majority were born to consanguineous parents and a few of them had positive family history of stone disease. Severe illness was found in 25 (20%) patients and among them 8 (32%) required hemodialysis. Decompression by double J stenting is the preferred intervention in our institute and was done in 106 (85%) children, followed by percutaneous nephrostomy tube in 10 (8%) successfully. A small number of patients, 9 (7%) required both procedures to relieve their obstruction. A significant number of patients, about 115 (92%), attained normal renal functions after intervention. No pertinent factors were identified, relating to incomplete renal recovery in nine (7%) of the patients who unfortunately progressed to chronic kidney disease.

Abstract
OBJECTIVE To evaluate the technical success rate and complications associated with percutaneous nephrostomy (PCN) via percutaneous renal access behind the stone and renal calyx dilation in patients with complex renal stones. MATERIALS AND METHODS From January 2010 to February 2021, we identified 69 patients with 70 complex renal stones who underwent PCN. Complex renal stones were classified as simple (renal pelvis only) (27.1%, 19/70), borderline staghorn (8.6%, 6/70), partial staghorn (51.4%, 36/70), or complete staghorn (12.9%, 9/70). All PCNs were performed under ultrasound and fluoroscopic guidance using one of two renal-entry techniques: puncture behind the stone (56%, 39/70) or renal calyx dilation (44%, 31/70). Then, we retrospectively evaluated the technical success rates and complications associated with each renal entry access technique. RESULTS The overall technical success rate was 100%, and the complication rate was 20.0% (14/70). For those who underwent renal access behind the stone, the complication rate was 15.4% (6/39), and six patients (six PCNs) had transient gross hematuria. For those who underwent dilated renal calyx entry, the complication rate was 25.8% (8/31), and one patient had significant bleeding complications requiring transfusion. Furthermore, seven patients (seven PCNs) had transient gross hematuria. Overall, the complication rates did not differ between the technique groups (p = 0.279). CONCLUSION PCN for complex renal stones has a high technical success rate and an acceptable complication rate regardless of the specific technique. Renal entry behind the stone is as safe and feasible as approaching via a dilated renal calyx.

Abstract
A lot of patients with nephrolithiasis have calculi at low pole calyces. One of the best and safety operative options of such category is retrograde intrarenal surgery (RIRS). RIRS is wide spread in current clinical practice. But not rarely it corresponded with different grade complications. Current literature review is dedicated to predictors of complications due to RIRS in patients with low pole calculi.

Abstract
To assess the efficacy and safety of robot-assisted anatrophic nephrolithotomy (RANL) as a choice of minimally invasive treatment for patients with complete staghorn stone. In a single-tertiary referral center retrospective study, 10 consecutive patients underwent RANL for complete staghorn stone. After dissection to the renal hilum and clamping of the renal vessels, an incision was made along the Brodel line and exposed the collecting system to extract the stone. Then, the collecting system and parenchyma were closed in layers. The outcomes included reduction of the stone burden, short- and long-term postoperative kidney function, and pain score. The average age of patients was 54.6 years and body mass index was 27.58 kg/m2. Mean warm ischemia time was 28.40 minutes, mean robotic console time was 137 minutes, and mean estimated blood loss was 83 mL. The mean length of stay was 5.4 days and there were no severe perioperative complications. Eight of 10 patients had >90% reduction in stone burden and 5 (50%) patients were completely stone-free. There was no significant decrease in postoperative estimated glomerular filtration rate compared with preoperative values after 1 month and 1 year. Our experience with RANL demonstrated efficacy and safety in the minimally invasive treatment of complete staghorn stone in short- and long-term follow-up periods.

Abstract
Introduction and objectives This Swiss LithoClast® Trilogy lithotrite is a new lithotrite for percutaneous nephrolithotomy (PCNL). It has four modifiable settings; impact, frequency, ultrasound and suction. We aim to determine the optimal device settings for the fastest stone clearance. Materials and methods Kidney stone phantoms were made with Begostone in a powder to water ratio (15:3–15:6). Complete stone clearance (seconds) was calculated and impact and frequency were adjusted and repeated N = 3. Intra renal pressure (IRP) was then measured in a porcine kidney model. Results Stone phantoms with physical properties similar to struvite were cleared best with 100% impact and frequency of 12 Hz. Both uric acid stone phantoms and calcium phosphate stone phantoms were cleared most efficiently with an impact of 30% and a frequency of 4 Hz. The mean time to clear uric acid stone phantoms was 83 s versus 217 s for calcium phosphate stone phantoms. Similarly, for calcium oxalate stone phantoms, an impact of 30% and a frequency of 4 Hz was associated with the fastest clearance time, mean 204 s. However, the differences between 4, 8 and 12 Hz were not statistically significant. At a suction level of 60% or higher, IRP became negative. Conclusion These results indicate that stone phantoms of hard kidney stones are cleared more efficiently at lower impact and frequency settings. With regard to suction, a setting of ≤ 50% appears to be the optimal setting.

Abstract
BACKGROUND Today, retrograde intrarenal surgery is the most preferred and very successful treatment method for upper ureteral stones that do not spontaneously pass and/or do not benefit from extracorporeal wave lithotripsy. However, perioperative complications are more common in retrograde intrarenal surgery if the stone in the ureter is impacted. Moreover, urosepsis and renal dysfunction are detected more frequently in patients with impacted stones. Impacted stones, which are a risky stone group even in patients with normal vertebral anatomy, are a more challenging situation in patients with advanced vertebral scoliosis. It is difficult to achieve an operating position in these patients. In addition, the ureteral tracing is altered, curved, and tortuous, making it more difficult for the endoscope to advance through the ureter. CASE PRESENTATION In this case report, we present a 23-year-old Caucasian male patient with right concavity and severe scoliosis, lower-extremity developmental disorder, and urosepsis. To treat the urosepsis picture, first percutaneous nephrostomy drainage was provided and the urine was sterilized with appropriate antibiotics according to the culture/antibiogram. Then, we performed ureterolithotripsy with a flexureterorenoscope. Finally, we see that flexible ureterorenoscopic lithotripsy to the upper ureteral stone with impacted stones, which is a very challenging operation even in patients with normal vertebrae, could be successfully performed in our patient with advanced scoliosis deformity. CONCLUSION High stone-free and low complication rates can be obtained with flexible ureterorenoscopic retrograde intrarenal surgery in medium-sized impacted upper ureteral stones in patients with advanced scoliosis.

Abstract
THE PURPOSE OF THE STUDY to develop a modern algorithm for the diagnosis and treatment of acute gestational pyelonephritis in a large industrial city and to study the possibilities of phytotherapy as an integral part of this algorithm. MATERIALS AND METHODS The study consisted of two stages and included 629 patients treated over 12 years (2010-2021) in Perm city with a population of 1.1 million people. At the first stage, the developed algorithm for the diagnosis and treatment of acute gestational pyelonephritis in 440 pregnant women was tested. A city emergency center for patients with gestational pyelonephritis was created with 3 urologists and related specialists on duty around the clock, what accelerated hospitalization timelines by 2.1 times. The patients underwent a level 1 examination, which included ultrasound examination, urine bacteriology and other methods. Patients in serve condition underwent, a level 2 examination, which included magnetic resonance imaging (MRI), ultrasound Dopplerography (USDG) and extended laboratory tests. RESULTS During an urgent examination, acute purulent pyelonephritis was diagnosed in 27 (6.1%) patients who underwent 13 open surgeries (11 organ-preserving, 2 nephroectomies) and 14 minimally invasive (percutaneous nephrostomy, puncture of a kidney abscess) within 2-5 hours from the moment of hospitalization. Serve obstructive pyelonephritis was diagnosed in 286 patients, the passage of urine was restored by the installation of a stent or catheterization of the ureter. Conservative antibacterial therapy was performed in 127 patients with serous non-obstructive pyelonephritis. Positive results of treatment were observed in 439 (99.8%) patients: recovery in 95%, significant improvement in 4.8%, with a mortality rate of 0.2%. Bed-day decreased by 30.4%. At the second stage, a comparative randomized study was conducted during 4 years with 189 pregnant women with acute serous pyelonephritis enrolled. In the group 1 (n=94) patients received standard therapy according to the implemented algorithm, in the group 2 (n=95) patients had 60-day use of Canephron N. In the group 2, treatment results were better: recovery was achieved in 96.8% of patients, improvement in 3.2%, the number of pregnant women with leukocyturia and bacteriuria decreased 4.1 times, which prevented the occurrence of repeated attacks of acute pyelonephritis. Compared with standard therapy, Canephron N increased glomerular filtration by 12,3%, diuresis by 14.2%, increased urea excretion function of the kidneys, sanitized the urinary tract at an earlier timelines, reduced the number of premature births and the birth of dead and premature babies. CONCLUSION As a result of the development and implementation of an algorithm for the diagnosis and treatment of acute gestational pyelonephritis and creation of the treatment center for such patients, it was possible to reduce significantly the time of hospitalization and inpatient treatment and achieve good treatment results in 99.8% of patients. The inclusion of long-term phytotherapy with Canephron N in the treatment regimen increased the effectiveness of treatment, improved kidney function in patients, significantly reduced the number of pregnant women with leukocyturia and bacteriuria, and reduced the risk of a repeated attack of pyelonephritis.

Abstract
OBJECTIVE To compare the outcomes of mini-PCNL (miniaturised percutaneous nephrolithotomy) in prone and supine positions in elderly patients. STUDY DESIGN Cohort study. PLACE AND DURATION OF STUDY Department of Urology, University of Health Sciences, Turkey, between April 2017 and January 2021. METHODOLOGY Patients over 65 years of age were included in the study. All patients' comorbidities were recorded and charlson comorbidity index (CCI) score was calculated. The groups were compared in terms of perioperative values, stone-free rates and complication rates. Logistic regression analysis was used to evaluate risk factors for complication development. Postoperative complications were noted according to the Clavien scoring system (CSS). RESULTS There were 54 patients in the supine mini-PCNL group and 64 in the prone mini-PCNL group. The median ages were 67 in the prone and 66 in the supine group. CCI scores were similar in both groups (p = 0.735). Stone-free and total complication rates were not statistically different in the groups (p = 0.994 and p = 0.247, respectively). However, grade 1-2 complication rates were significantly higher in the prone group (p=0.020). CCI score and stone size were significantly associated with the development of complications (p = 0.018 and p = 0.034, respectively). CONCLUSION The present study is the first to compare the outcomes of mini-PCNL in prone and supine position in geriatric patients. Supine mini-PCNL is a potentially safer alternative treatment method for older patients with high CCI scores. Key Words: Percutaneous nephrolithotomy, Supine position, Elderly, Mini-PCNl, CCI score.

Abstract
INTRODUCTION Parapelvic renal cysts are very common. Indications for surgical treatment are upper urine tract obstruction, pain and recurrent gross hematuria. AIM To analyze the efficiency and safety of endoscopic transurethral and percutaneous laser marsupialization of parapelvic renal cysts. MATERIALS AND METHODS A total of 9 patients were undergone to transurethral intrarenal marsupialization of parapelvic renal cysts from March 2016 to February 2021 (4 men, 5 women, aged 42-78 years). Another 2 patients (2 men, aged 46 and 52 years) were treated by percutaneous approach. The average size of the cyst according to contrast-enhanced multi-slice computed tomography (MSCT) was 3.1+/-1.8 cm. In two cases, papillary tumor of the pelvis was suspected. The anteroposterior diameter of the pelvis was 2.6+/-1.3 cm; 9 patients had pain in the loin area, while in 7 patients recurrent gross hematuria was also an indication for surgical treatment. For marsupialization, a holmium (Ho:YAG) laser Auriga XL (Boston Scientific, USA) was used in 4 patients, and in other cases (n=7) a procedure was performed using a thulium fiber laser (Tm Fiber) Fiberlase U1 (IRE-Polus, Russia). In 3 patients, to clarify the site of incision of the cyst, intraoperative ultrasound was used. In all cases, after draining the cyst, an internal stent was placed inside the cyst for a period of 4-6 weeks. RESULTS The duration of transurethral surgery was 26+/-11 minutes, while percutaneous marsupialization of the cyst, which was performed in combination with percutaneous nephrolithotomy, took 10 and 18 minutes, respectively. The average catheterization time was 12+/-8 hours. Nephrostomy tube was removed on the 2nd day. The length of stay was 4+/-2 days. Febrile fever was noted in 1 patient (9%), which required a change in antibiotic therapy. During ultrasound control at discharge, the dilatation of the collecting system was not detected in any cases, while the residual cavity was found in 2 patients (18%). Follow-up contrast-enhanced MSCT and ultrasound within 3-30 months in all patients (n=11) showed no dilatation of the collecting system. In 1 (9%) patient, the residual cavity was preserved with a decrease in size to 1.2 cm without signs of upper urinary tract obstruction; the initial diameter of the cyst in this patient was 4.9 cm. There was no recurrence of gross hematuria. CONCLUSIONS In our opinion, transurethral and percutaneous laser marsupialization of parapelvic renal cysts is an effective and safe method that allows definitive treatment for cysts up to 4 cm in size. If the cyst is larger than 4 cm, endoscopic removal should be balanced with the possibility of preserving the residual cavity. The most common complication of endoscopic treatment of intrarenal cysts is acute pyelonephritis with a rate of 9%.

Abstract
Purpose To investigate the puncture accuracy and feasibility of contrast-enhanced ultrasound (CEUS) guided percutaneous nephrolithotomy (PCNL) in flank position for patients with no apparent hydronephrosis. Methods Between May 2018 and June 2020, 72 kidney stone patients with no or mild hydronephrosis were randomized into two groups: a CEUS-guided PCNL group and a conventional ultrasound (US)-guided group. Patients’ demographics and perioperative outcomes were compared, including the success rate of puncture via calyceal fornix, the success rate of a single-needle puncture, puncture time, operative time, postoperative hemoglobin loss, stone-free rate, incidence of complications and postoperative stay. Results The success rate of puncture via calyceal fornix for CEUS-guided group was significantly higher than that for conventional US-guided group (86.1 vs. 47.2%, p = 0.002). Patients performed with CEUS-guided PCNL required shorter renal puncture time than those guided with conventional US (36.5 s vs. 61.0 s, p < 0.001). The median postoperative hemoglobin loss in the CEUS-guided group was significantly lower than that in conventional US-guided group (2.5 vs. 14.5 g/L, p < 0.01). There was no statistically significant difference in the success rate of a single-needle puncture, operative time, stone-free rate, incidence of complications and postoperative stay between the two groups. Conclusion CEUS guidance facilitates identification of the renal calyx fornix, and benefits more precise renal puncture and less hemoglobin loss in PCNL. CEUS-guided PCNL in flank position is a feasible approach to the treatment of kidney stone patients with no apparent hydronephrosis.

Abstract
OBJECTIVE The aim: To summarize the state of the problem of urolithiasis in patients with a single kidney and consider current views on improving its treatment based on the analysis of world literature. PATIENTS AND METHODS Materials and methods: The study conducted a thorough analysis of modern scientific literature sources in the international scientometric database, which highlighted the development of urolithiasis in patients with a single kidney and the peculiarities of its treatment. The main ways to improve treatment are identified. A critical assessment of the achievements and shortcomings of various surgical treatments. The authors' own developments are presented in the article. CONCLUSION Conclusions: The topographic position of the kidney in the retroperitoneal space affects not only the occurrence of pathological processes in the kidney, but also the surgical strategy in the treatment of nephrolithiasis. Percutaneous nephrolithotomy is the main treatment for large (> 2 cm) or complex kidney stones. Patients with a single kidney are more prone to bleeding with PCNL treatment than patients with bilateral kidneys because they have an increased thickness of the renal parenchyma as a result of compensatory hypertrophy. RIRS is a reliable choice for patients with a single kidney who is contraindicated in PCNL.

Abstract
OBJECTIVE Mini-percutaneous nephrolithotomy is a recent advancement in the field of kidney stone treatment; however, its role has not been completely established. We aimed to compare the outcomes of initial Mini-percutaneous nephrolithotomy and flexible ureteroscopy. METHODS A retrospective review of consecutive mini-percutaneous procedures was performed. Inclusion criteria were as follows: all percutaneous nephrolithotomy procedures performed with an access sheath up to 24Fr, kidney stone burdens up to 1550 mm3; and the presence of postoperative computed tomography (for control). The data collected for Mini-percutaneous nephrolithotomy procedures were paired 1:2 with patients treated with flexible ureteroscopy for stones between 100 and 1550 mm3, and with postoperative computed tomography for control. A 14Fr Mini-percutaneous nephrolithotomy set was used. The stone-free rate was defined as the absence of fragments on the control computed tomography, whereas success was limited to 2-mm residual fragments. Statistical analysis was performed using SPSS version 19. RESULTS A total of 63 patients met the inclusion criteria (42 with flexible ureteroscopy and 21 with mini-percutaneous nephrolithotomy). Demographic data were comparable. The stone-free rate and success were similar between the groups (76.2 vs. 66.7%, p=0.42 and 90.5 vs. 85.7%, p=0.57). The complication rate was also similar (26.1 vs. 9.6%, p=0.188), but Mini-percutaneous nephrolithotomy had longer hospitalization and fluoroscopy time (p=0.001 in both). CONCLUSIONS Our initial study of Mini-percutaneous nephrolithotomy showed that it is a promising procedure, with outcomes similar to flexible ureteroscopy, but with higher inpatient numbers and fluoroscopy times. A larger study population size and better equipment may improve the outcomes of mini-percutaneous nephrolithotomy.

Abstract
OBJECTIVE To compare the efficacy and safety of prone and supine percutaneous nephrolithotomy (P/SPNL) with special emphasis on tubeless (T) and totally tubeless (TT) surgery. MATERIAL AND METHODS This retrospective, single-surgeon, consecutive series comparison study involved 361 consecutive patients who under went PNL operations in either the prone or Galdakao-modified Valdivia supine positions between September 2016 and March 2020. Indication for surgery was a stone diameter greater than 2 cm. The two groups were compared in terms of preoperative demographics, stone parameters, and perioperative data. RESULTS The groups were similar in terms of preoperative demographics, while the blood transfusion rate was insignificantly higher in PPNL (7% vs 3.3%, p=0.165). Mean operative time (58.0±20.6 vs 54.1±15.9 min., respectively, p=0.165), fluoroscopy time (p=0.895), and Clavien complication rates (p=0.87) were similar. SPNL exhibited a significantly (p<0.001) higher rate of T operations (23, 37.7%) than PPNL (46, 15.3%). TT cases were also higher with SPNL (14% vs 29.5%,p=0.003). Urine leakage (p=0.085) and post-operative JJ stent placement (p=0.180) rates were statistically similar between the two groups. Length of hospital stay was approximately one day shorter for T cases in both groups (PPNL: 1.37±0.80 vs 2.26±1.28 days, p=0.001; SPNL: 1.65±0.83 vs 2.76±2.27 days, p=0.028). Stone free rates were 91.3% and 88.5% for PPNL and SPNL, respectively (p=0.488). CONCLUSION SPNL has proved to be as safe and effective as its prone counter part, with similar stone-free and complication rates. T and TT-PNL seem more viable with SPNL, which will increase patient comfort and allow shorter hospitalization times.

Abstract
AIM To determine the possibility of performing minimally invasive percutaneous nephrolithotomy (PCNL) under ultrasound guidance with the use of X-ray during the access tract formation. MATERIALS AND METHODS The results of 102 mini-PNL procedures, performed by a single surgeon during the period 2018-2019, were analyzed retrospectively. In the beginning, ureteral catheter Ch5 was put into an ipsilateral ureter. Further, a puncture of the collecting system was performed with an advancement of the guidewire. At the next stage, a dilation of tract was done using X-ray guidance for the safe formation of the working channel, followed by holmium lithotripsy. At the end a nephrostomy or JJ-stent was left. RESULTS The mean age of the patients was 53.13+/-12.9, while average BMI was 29.3+/-6.5. In total, there were 44.1% of women. The average stone size was 20.7+/-10.9 mm; 45.1% of stones were left-sided. Staghorn stones accounted for 15.7% of cases and hydronephrosis was found in 18.6% of patients. The time for creating renal access, dilation of the nephrostomy tract, total operative time and fluoroscopy time were: 19.6+/-13.1, 7.7+/-4.2, 107.7+/-49.9, 57.1+/-41.2 minutes, respectively. In the Group I there were 32 (31.4%) patients undergoing to PCNL under X-ray guidance, while in Group II (n=70, 68.6%) combined US+/-X-ray control was used. The patients age (52.2+/-12.6 vs 53.6+/-13.2, p<0.05) and the stone size (20.6+/-8.9 vs 20.7+/-10.4, p=0.30) were comparable in both groups. There were slightly shorter access time and the total operative time in group II compared with group I (20.6+/-12.3 vs 19.2+/-13.5, p=0.27; 108.1+/-43.3 vs 106.9+/-53.2, p=0.25 respectively). In total, hematocrit level decreased by 4.5% and blood transfusions was done in 3 patients. Postoperative complications developed in 9 cases in both groups (according to the Clavien-Dindo classification, all complications were grade I-II). The stone-free rate (SFR) was 87.2%, and a second-stage was required in 2 cases. DISCUSSION The use of ultrasound guidance improves visualization of the collecting system and contributes to the creation of an optimal renal access. It significantly reduces the radiation exposure to the patient and the operating team. We were able to puncture the collecting system in all cases. SFR after PCNL under ultrasound guidance was 88.6%, which is comparable to the results of conventional PCNL with X-ray navigation. CONCLUSION PCNL can be performed effectively and safely under ultrasound guidance, which reduces the number of renal punctures and lowers the complication rate. However, this technique also has disadvantages, including longer puncture time in morbidly obese patients without hydronephrosis. With growing experience, the number of unsuccessful kidney punctures decreases, as well as operative time. The use of fluoroscopy during dilatation of the nephrostomy tract allows for preventing additional injuries of the collecting system.

Abstract
Introduction: Currently, there are multiple intracorporeal lithotripters available for use in percutaneous nephrolithotomy (PCNL). This study aimed to evaluate the efficiency of two novel lithotripters: Trilogy and ShockPulse-SE. Materials and Methods: This is a prospective multi-institutional randomized trial comparing outcomes of PCNL using two novel lithotripters between February 2019 and June 2020. The study assessed objective measures of stone clearance time, stone clearance rate, device malfunction, stone-free rates, and complications. Device assessment was provided through immediate postoperative survey by primary surgeons. Results: There were 100 standard PCNLs completed using either a Trilogy or ShockPulse-SE lithotrite. Using quantitative Stone Analysis Software to estimate stone volume, the mean stone volume was calculated at 4.18 ± 4.79 and 3.86 ± 3.43 cm3 for the Trilogy and ShockPulse-SE groups, respectively. Stone clearance rates were found to be 1.22 ± 1.67 and 0.77 ± 0.68 cm3/min for Trilogy vs ShockPulse-SE (p = 0.0542). When comparing Trilogy to ShockPulse-SE in a multivariate analysis, total operative room time (104.4 ± 48.2 minutes vs 121.1 ± 59.2 minutes p = 0.126), rates of secondary procedures (17.65% vs 40.81%, p = 0.005), and device malfunctions (1.96% vs 34.69%, p < 0.001) were less, respectively. There was no difference in final stone-free rates between devices. Conclusion: Both the Trilogy and ShockPulse-SE lithotripters are highly efficient at removing large renal stones. In this study, we noted differences between the two devices including fewer device malfunctions when Trilogy device was utilized. Clinical Trial ID number: NCT03959683.

Abstract
INTRODUCTION To make percutaneous access easier in PCNL, we developed Automated Needle Targeting with X-ray (ANT-X). METHOD ANT-X uses an image registration software with a closed loop feedback system to autoalign the puncture needle to the desired calyx using the bullseye technique. We tried percutaneous punctures on a live pig model and compared the results with free-hand technique. We then performed our first PCNL in a human subject with the aid of ANT-X. Our patient was a 48 year-old gentleman with a 1.4cm left lower pole stone. RESULTS Initial results for live animal trial showed radiation exposure for robot-assisted arm during puncture was reduced by 26% compared to the free-hand technique (8.2mGy vs 11.2mGy). In the human trial, obtaining percutaneous access was successful at first attempt. CONCLUSION ANT-X system can help surgeons feel confident and potentially reduce complications, hence enabling more surgeons to adopt this procedure.

Abstract
PURPOSE The aim of this study is to identify the changes in patient age and stone sizes with technological advancement over time. METHODS This study was conducted retrospectively with 404 patients (504 renal units) who underwent percutaneous nephrolithotomy (PCNL) between January 1997 and June 2020. Patient characteristics and trends on instrument preferences were investigated. RESULTS Median age was 7 (1-18) years. Male to female ratio was 1.48:1 (301/203). Median stone burden was 2 cm2 (0.20-25) and median operative time was 90 minutes (20-240). The stone-free rate was 74.6%. Patients were divided into four groups according to the size of the instrument. It was found that the size of sheath used increased significantly with increasing age and stone burden. The micro-PCNL group had the shortest hospitalisation and lowest blood transfusion rate. Chronologically categorised four equal groups were compared to analyse changing patient profiles and trends. Median patient age, stone burden, operation time, sheath size, blood transfusion and complication rates decreased significantly with time. However, the use of tracts smaller than 20F and the number of patients with previous intervention increased significantly. CONCLUSION Our study demonstrated that the patient's age and stone size at the time of initial diagnosis decrease over time while miniaturisation techniques increase in paediatric urology.
