We assessed the usefulness of LigaSure (Valleylab, Boulder, Colorado) vessel sealing system for vascular control during laparoscopic surgery and compared it with other available hemostatic modalities.A total 31 domestic pigs were divided into 5 groups. In groups 1 2 was titanium clips Endo-GIA (United States Surgical, Stamford, Connecticut) staples. group 3 standard Klepinger (Karl Storz, Culver City, California) bipolar forceps. 4 harmonic scalpel Trimax Surgical) forceps compared. in vivo...
OBJECTIVE. The objective of our study was to assess the value diffusion-weighted imaging in differentiating among various subgroups renal masses.
Purpose: The primary objective of this study is to determine if training on the Mimic dV-Trainer (MdVT) simulator results in improved ability da Vinci® surgical system (dVSS) using exercises with inanimate objects. Materials and Methods: Twelve trainees (MdVT group) 10 residents one fellow (dVSS were recruited for study. Each participant MdVT group completed session five dVSS that scored timing accuracy, followed by four sessions MdVT, concluded a final which initial repeated. Improvement...
Purpose: We evaluated the face, content, and construct validity of what is, to our knowledge, only available virtual reality simulator based on a complete kinematic representation da Vinci® surgical system. Materials Methods: A total 5 experts (EPs) 15 novices (NVs) completed exercises Mimic dV-Trainer (MdVT). All participants three repetitions following tasks: (1) Ring Cone, (2) String Walk, (3) Letterboard. Participants rated parameters face content five-point Likert-scale questionnaire....
Given the importance of correctly staging renal cell carcinomas, specific guidelines should be in place for tumor size measurement. While a standard means measurement has not been established, intuitively, based on fresh measurements. We sought to assess accuracy postfixation and microscopic measurements size, as compared radiographic size. Thirty-four nephrectomy cases performed by single surgeon were prospectively measured at different time points. The study included 23 clear 6 papillary 5...
Objective The aim of this study is to assess the relationship between eye-tracking measures and perceived workload in robotic surgical tasks. Background Robotic techniques provide improved dexterity, stereoscopic vision, ergonomic control system over laparoscopic surgery, but complexity interfaces operations may pose new challenges surgeons compromise patient safety. Limited studies have objectively quantified its impact on performance surgery. Although not yet implemented minimally...
Purpose: To compare the outcomes of robotic radical nephroureterectomy (RRNU) and laparoscopic (LRNU) within a large multi-institutional worldwide dataset. Materials Methods: The ROBotic surgery for Upper tract Urothelial cancer STudy (ROBUUST) includes data from 17 centers regarding 877 RRNU LRNU performed between 2015 2019. Baseline features, perioperative oncologic outcomes, were included. A 2:1 nearest-neighbor propensity-score matching with 0.001 caliper was performed. univariable...
We compared the efficacy of shock wave lithotripsy and ureteroscopy for treatment distal ureteral calculi.A total 64 patients with solitary, radiopaque calculi 15 mm. or less in largest diameter were randomized to (32) using an HM3 lithotriptor (Dornier MedTech, Kennesaw, Georgia) (32). Patient stone characteristics, parameters, clinical outcomes, patient satisfaction cost assessed each group.The 2 groups comparable regard age, sex, body mass index, size, degree hydronephrosis time...
Flexible ureteroscopes smaller than 9Fr are widely used in endourology. We systematically evaluated the functional durability of these instruments clinical setting.We performed ureteronephroscopy 92 consecutive times 84 patients at our hospital using a flexible Storz model 11274AA,double dagger Circon-ACMI AUR-7, section sign Wolf 7325.172 parallel and Olympus URF/P3 ureteroscope paragraph sign. Preoperatively postoperatively we all for luminosity, irrigant flow 100 mm. Hg, number broken...
Purpose: To assess the impact of development less powerful second- and third-generation shockwave lithotripters on surgical stone therapy in light recent advances ureteroscopy laser lithotripsy. As such, we sought to identify current trends treatment disease, both at our university medical center nationally, contrast them with corresponding data from 1990. Patients Methods: All urolithiasis procedures (ureteroscopy, SWL, open surgery, percutaneous removal) performed 1998 were compared all 8...
Laparoscopic pyeloplasty has become a viable option for the treatment of select patients with primary ureteropelvic junction obstruction success rates similar to those open surgery. However, little been written on application this technique secondary obstruction. We report largest series managed by laparoscopic pyeloplasty.Between March 1994 and 2001, 36 underwent transperitoneal The had undergone an average 1.3 procedures (range 1 4) prior presentation, including cutting balloon retrograde...
Since the first report of robotic management renal tumors with inferior vena cava tumor thrombi, few additional cases have been reported in literature. We our combined experience this procedure, to knowledge multi-institutional and largest series date.A retrospective, review nephrectomy thrombectomy was performed institutional board approval.A total 32 were among 9 surgeons at institutions since known procedure 2008. Of these 30 level II 2 III thrombi no I (renal vein only) included...
Comparison of treatments for partial nephrectomy is limited by case selection. We compared robotic (RPN), laparoscopic (LPN), and open (OPN), controlling tumor size, patient age, sex, nephrometry score.RPN, LPN, OPN procedures between March 2003 2010 were reviewed. All RPN LPN included, 2 matched each in size (±0.5cm), age (±10 y), score. Perioperative outcomes compared.Ninety-six reviewed: 27 RPN, 15 54 OPN. had similar median (2.4, 2.2, 2.3cm, respectively), score (6.0 each), preoperative...
To assess the safety of omitting cortical renorrhaphy during robot-assisted partial nephrectomy and measure preliminary functional outcomes.Fifteen nephrectomies were performed with a running, base-layer suture for collecting system vessel hemostasis but without renorrhaphy. The nonrenorrhaphy group was matched 1:2 by R.E.N.A.L. nephrometry score to sliding-clip retrospectively. Intraoperative blood loss, urine leaks, postoperative bleeds, outcomes evaluated. Predictors %volume loss...
To compare outcomes of minimally invasive radical nephrectomy (MIS-RN) and robot-assisted partial (RAPN) in clinical T2a renal mass (cT2aRM).Retrospective, multicentre, propensity score-matched (PSM) comparison RAPN MIS-RN for cT2aRM (T2aN0M0). Cohorts were PSM age, sex, body index, American Society Anesthesiologists (ASA) class, tumour size, R.E.N.A.L. score using a 2:1 ratio RN:PN. The primary outcome was disease-free survival (DFS). Secondary included overall (OS), complication rates, de...
We compared perioperative outcomes after on-clamp versus off-clamp robot-assisted partial nephrectomy (RAPN) for >7 cm renal masses. A multicenter dataset was queried patients who had undergone RAPN a cT2cN0cM0 kidney tumor from July 2007 to February 2022. The Trifecta achievement (negative surgical margins, no severe complications, and ≤ 30% postoperative estimated glomerular filtration rate (eGFR) reduction) considered surrogate of quality. Overall, 316 cases were included in the analysis,...
