Background: Sotn ureteroscopy is a new lithotripsy procedure developed on the basis of ureteroscopy and includes a rigid ureteral access sheath, standard mirror, lithotripsy mirror, and Sotn perfusion aspirator. Thus, we performed a prospective multicenter randomized controlled trial comparing the safety and efficacy of Sotn ureteroscopy in the treatment of renal and upper ureteral calculi.
Methods: In this study, 224 patients with renal and upper ureteral calculi were randomly divided equally into study and control groups from March 2018 to March 2022. All the patients were approved by the hospital ethics committee (proof number: ZF-2018-164-01 and ZF-2018-165-01) of the Second Affiliate Hospital of Guangzhou University of Chinese Medicine in China. The primary outcome was stone-free rate (SFR) assessed by computed tomography on the 1st day and month after treatment and operation duration. The secondary outcome was postoperative complication rate.
Results: In total, for upper ureteral calculi, the SFR of 1 day after operation of the Sotn ureteroscopy group was significantly higher than the rigid ureteroscopy group (83.6% vs. 60%, P=0.006). Moreover, operative time (33.7±1.80 vs. 52.9±2.73 min, P<0.005) of the Sotn ureteroscopy group was significantly lower than the rigid ureteroscopy group. Additionally, the SFR of 1 day after operation and operative time for the study group (Sotn ureteroscopy combined with flexible ureteroscopy) and the control group (flexible ureteroscopy alone) were 63.2% and 36.8% (P=0.005), 65.6±4.06 and 80.3±4.91 (P=0.023), respectively. However, there were no significant differences in the SFR of 1 month after operation, success rate of ureteral access sheath placement, and postoperative complications between the two groups (P>0.05). In subgroups with stone diameters ≥1.5 cm and stone CT values ≥1000 Hounsfield units, Sotn ureteroscopy showed more advantages in terms of the SFR of 1 day after operation. Importantly, complications such as ureteral injury, sepsis, fever, and severe hematuria were not statistically different between the two groups (P>0.05).
Conclusions: For renal and upper ureteral calculi, Sotn ureteroscopy has the advantage of a higher SFR of 1 day after the operation and a shorter operative time, suggesting that the Sotn ureteroscopy may have further potential applications in clinics.

Background: The aim of this study is to evaluate the perioperative and long-term functional outcomes of laparoscopic (LPN) and robot-assisted partial nephrectomy (RAPN) in comparison to laparoscopic radical nephrectomy (LRN) in obese patients diagnosed with renal cell carcinoma.
Methods: Clinical data of 4325 consecutive patients from The Italian REgistry of COnservative and Radical Surgery for cortical renal tumor Disease (RECORD 2 Project) were gathered. Only patients treated with transperitoneal LPN, RAPN, or LRN with Body Mass Index (BMI) ≥30 kg/m2, clinical T1 renal tumor and preoperative estimated glomerular filtration rate (eGFR) ≥60 mL/min, were included. Perioperative, and long-term functional outcomes were examined.
Results: Overall, 388 patients were included, of these 123 (31.7%), 120 (30.9%) and 145 (37.4%) patients were treated with LRN, LPN, and RAPN, respectively. No significant difference was observed in preoperative characteristics. Overall, intra and postoperative complication rates were comparable among the groups. The LRN group had a significantly increased occurrence of acute kidney injury (AKI) compared to LPN and RAPN (40.6% vs. 15.3% vs. 7.6%, P=0.001). Laparoscopic RN showed a statistically significant higher renal function decline at 60-month follow-up assessment compared to LPN and RAPN. A significant renal function loss was recorded in 30.1% of patients treated with LRN compared to 16.7% and 10.3% of patients treated with LPN and RAPN (P=0.01).
Conclusions: In obese patients, both LPN and RAPN showcased comparable complication rates and higher renal function preservation than LRN. These findings highlighted the potential benefits of minimally invasive PN over radical surgery in the context of obese individuals.

Background: The debate between single-layer and double-layer renorrhaphy techniques during robot-assisted partial nephrectomy (RPN) represents a subject of ongoing discourse. The present analysis aims to compare the perioperative and functional outcomes of single- versus double-layer renorrhaphy during RPN.
Methods: Study data were retrieved from prospectively maintained institutional database (Jan2018-May2023). Study population was divided into two groups according to the number of layers (single vs. double) used for renorrhaphy. Baseline and perioperative data were compared. Postoperative surgical outcomes included type and grade of complications as classified according to Clavien-Dindo. Serum creatinine and estimated glomerular filtration rate were used to measure renal function.
Results: Three hundred seventeen patients were included in the analysis: 209 received single-layer closure, while 108 underwent double-layer renorrhaphy. Baseline characteristics were not statistically different between the groups. Comparable low incidence of intraoperative complications was observed between the cohorts (P=0.5). No difference was found in terms of mean (95% CI) Hb level drop postoperation (single-layer: 1.6 g/dL [1.5-1.7] vs. double-layer: 1.4 g/dL [1.2-1.5], P=0.3). Overall and "major" rate of complications were 16% and 3%, respectively, with no difference observed in terms of any grade (P=0.2) and major complications (P=0.7). Postoperative renal function was not statistically different between the treatment modalities. At logistic regression analyses, no difference in terms of probability of overall (OR 0.82 [0.63-1.88]) and major (OR 0.94 [0.77-6.44]) complications for the number of suture layers was observed.
Conclusions: Single-layer and double-layer renorrhaphy demonstrated comparable perioperative and functional outcomes within the setting of the present study.

Background: To evaluate the feasibility and safety of dual-console telesurgery with the new KangDuo system in an animal experiment and clinical study.
Methods: Six canine models were performed radical prostatectomy with dual-console KanDuo surgical robot-1500 (KD-SR-1500-RARP). The perioperative outcomes, physical and mental workload of the surgeon were collected. Physical workload was evaluated with surface electromyography. Mental workload was evaluated with NASA-TLX. After conducting animal experiments to verify safety of dual-console KD-SR-1500-RARP, we conducted the clinical trial using 5G and wired networks.
Results: In the animal experiment, all surgeries were performed successfully. The operative time was 80.2±32.1 min. The docking time was 2.4±0.5 min. The console time was 49.7±25.3 min. There were no perioperative complications or equipment related adverse events. All dogs can micturate after catheter removal at one week postoperatively. The mental workload was at a low level (a scale ranging from 0 to 60), which scored 15.7±6.9. Among the eight recorded muscles, the fatigue degree of the right radial flexor and left biceps was the highest two (iEMG, resection, 299.8±344 uV, 109.9±16.9 uV; suture, 849.4±1252.5 uV, 423.1±621.3 uV, respectively). In the clinical study, the console time was 136 min. The mean latency time was ≤200 ms. The data pocket loss was <1%. The operation was successfully completed without malfunctions occurring throughout the entire process.
Conclusions: Dual-console telesurgery with the KD-SR-1500 system was shown to be feasible and safe in radical prostatectomy using 5G and wired networks.

Herein we report our first experience with Hugo RAS™ proposing a mirrored approach with different angles. Two experienced surgeons performed 10 prostatectomies (six with the standard approach and four with the mirrored one). The median docking time was 12.5 (IQR 12-15) vs. 13.5 (IQR 12-20) minutes. The median console time was 229 (174-245) vs. 172 (IQR 164-191) minutes. None of the procedures required conversion to open surgery. The study proves the versatility of the Hugo RAS™ to perform robot-assisted radical prostatectomy with two different docking angles and might be useful for novel users to adopt the preferred approach.

Background: Recurrent and complex stone disease may be considered a challenging disease. In 2018, the Calculus group of the SIU (Italian Society of Urology) set itself the goal of establishing the minimum requirements for a center that could continuously manage urolithiasis pathology, named a Stone Center. In this study we present the results of a pilot survey carried out in 2019 with the aim of drawing a map of the situation of Italian urological centers dealing with urinary stones.
Methods: A total of 260 national urology departments dealing with urolithiasis surgery were contacted for this study. A survey was issued to each of the centers to determine the number of patients treated for urinary stones and the amount of procedures performed per year: 1) extracorporeal shock wave lithotripsy ESWL; 2) ureterorenoscopy URS; 3) retrograde intrarenal surgery RIRS; 4) percutaneous nephrolithotomy PCNL.
Results: Out of 260 centers contacted, 188 fulfilled the survey. Outcomes were quite variable, with approximately 37% of the centers lacking a lithotripter, and 46% of those that did have it performing fewer than 100 treatments per year. In terms of endoscopic procedures, more than 80% of the centers contacted performed URS or RIRS; however, when it came to percutaneous lithotripsy, these numbers dropped significantly; 33% of the centers contacted did not perform PCNL, and of those who did, 18% had less than 5 years of experience as a center.
Conclusions: Our survey shows a very heterogeneous national picture about urolithiasis treatments. Our goal is to create national paradigms to be able to define stone centers where the patient suffering from complex urinary stones can find a network of professionals with an adequate armamentarium suitable for the management of their pathology.

Background: Transient urinary incontinence (UI) is distressing event following holmium laser enucleation of the prostate (HoLEP). Novel technique namely, veil sparing HoLEP (VS-HoLEP), was proposed to improve early continence outcome. In this trial (NCT03494049), VS-HoLEP was compared to standard HoLEP (St-HoLEP).
Methods: VS-HoLEP entails early apical separation with sparing of ventral apical mucosal veil proximal to the verumontanum. Eligible symptomatic BPH patients were randomly allocated to St-HoLEP (91) and VS-HoLEP (89). The primary outcome was UI as depicted by one-hour pad test at one month postoperatively. Other outcome measures include all perioperative parameters, complications, and urinary outcome measures at different follow-up points.
Results: Median preoperative prostate size was 138 (50:282) and 128 (50:228) mL in St-HoLEP and VS-HoLEP groups respectively. At one month the number of patients with positive one-hour pad test was 21 (23.1%) and 10 (11.4%) in St-HoLEP and VS-HoLEP groups respectively (P 0.047). The difference was significantly in favor of VS-HoLEP considering the number of patients reporting UI, the number of patients with positive one-hour pad test as well as the grade of UI reported at one and 4 months. The difference was not statistically significant at 12 months. The median time to patients' reported continence was 8 (1-52) and 1.5 (1-52) weeks in St-HoLEP and VS-HoLEP groups respectively (P≤0.005). The technique independently predicted positive one-hour pad test at one and four months respectively. At twelve months presence of DM (diabetes mellitus) and more percent PSA reduction independently predicted positive one-hour pad test.
Conclusions: Veil sparing HoLEP enhances significantly early postoperative urine continence both subjectively and objectively. Optimization of the surgical technique could cut short the number of leaking patients and reduce the degree as well as the duration of transient postoperative urine leak.
