Abstract Nephrolithiasis is one of the most common indications for surgery in patients with a horseshoe kidney. Robotic assisted surgery has become a staple in urologic practice, yet its application in stone management is largely undefined. We present a patient with a horseshoe kidney, who underwent a robotic-assisted laparoscopic pyelolithotomy (RPL) to treat a 3 cm stone burden. This procedure allowed for safe access that could not be obtained with percutaneous nephrolithotomy (PCNL) and stone removal without fragmentation, which would have been challenging with traditional laparoscopy. We advocate for the use of robotic-assisted laparoscopic pyelolithotomy in More >

Abstract Introduction: We describe a method of robotic ureterocalicostomy (RALUC) with the Da Vinci Single Port (SP) platform and present clinical outcomes in our cohort of patients.
Materials and methods: We retrospectively reviewed all patients undergoing RALUC with the SP platform in a single-institution, IRB-approved database between 2020 2023. Demographics, preoperative, intraoperative, and postoperative outcomes were collated. Surgical success was defined as freedom from hardware, avoidance of additional surgical reconstruction, and no obstruction on follow up imaging/ureteroscopy.
An incision is made 1/3rd the distance from anterior superior iliac spine to the umbilicus. The retroperitoneal space is entered and SP… More >

Abstract Introduction: To evaluate the utility, outcomes, and cost of arterial line placement in a single institution cohort of patients undergoing robotic-assisted laparoscopic prostatectomy (RALP).
Materials and methods: A retrospective chart review was performed at a large tertiary care center from July 2018 through January 2021. Hospital costs and cost-effective analysis was performed on patients with and without arterial line placement. Means with standard deviations were used to report continuous variables, while numbers and percentages were utilized to describe categorical variables. T-tests and Chi-square tests compared categorical and continuous variables across study cohorts, respectively. Multivariable analyses were used… More >

Abstract Introduction: To clarify the efficacy and safety of propiverine hydrochloride for incontinence after robot-assisted laparoscopic prostatectomy (RALP)/laparoscopic radical prostatectomy (LRP), along with changes in the urethral pressure profile (UPP) and quality of life in patients treated with propiverine hydrochloride.
Materials and methods: In this randomized, comparative study, 104 patients who were aware of urinary incontinence after RALP or LRP were assigned to receive propiverine hydrochloride (treatment group) or not (controls). Pad test results, International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) scores, and UPP results [including maximum urethral closure pressure (MUCP) and functional urethral length (FUL)], were recorded… More >

Abstract Introduction: Management of pediatric renal masses has lagged behind adult paradigms adopting minimally invasive surgery (MIS) and nephron-sparing surgery (NSS). This study investigated national practice patterns between pediatric urologists (PU) and pediatric surgeons (PS) in pediatric renal malignancy.
Materials and methods: The Pediatric National Surgical Quality Improvement Program database was queried for CPT codes for radical/partial nephrectomy from 2012-2017 performed for renal malignancy. Patients were grouped by specialty and operative approach.
Results: PU managed 175 (17%) patients while PS managed 811 (77%). PU were more likely to use MIS (14% versus 5%, p < 0.001) and NSS (33%… More >

Abstract Introduction: To explore postoperative operation-side renal functional outcome after laparoscopic partial nephrectomy (LPN) using dynamic renal scintigraphy.
Materials and methods: Between July 2006 and December 2014, 62 patients with localized renal tumor received ischemic LPN at our institution. Preoperative, 6 months postoperative, and 12 months postoperative split renal functions were evaluated by dynamic renal scintigraphy using radionuclide technetium-99m-mercaptoacetyltriglycine. Postoperative operation-side renal function was calculated. To assess the significant factors affecting postoperative operation-side renal functional decrease, simple regression and multiple regression analyses were carried out.
Results: Postoperative operation-side renal functions were significantly decreased to 86.6% at 6 months and… More >

Abstract Ulinastatin combined with dexmedetomidine can improve postoperative cognitive function and central nerve specific protein (S-100β) level in elderly colorectal cancer (CC) patients after laparoscopic. Altogether 178 elderly patients who underwent laparoscopic colorectal cancer surgery in our hospital from February 2018 to August 2019 were selected and divided into two groups according to the treatment methods. Those anesthetized by dexmedetomidine were regarded as the routine group (RG, 83 cases), and those anesthetized by ulinastatin and dexmedetomidine were considered as the combined group (CG, 95 cases). The operation conditions of the two groups, the pain scores (VAS)… More >

Abstract Laparoscopic surgery is a relatively new field in developing countries. There is a scarcity of laparoscopically trained doctors due to a lack of training and resources available in hospitals. Training and evaluation of medical professionals to develop laparoscopic surgical skills are important and essential as it improves the success rate and reduces the risk during real surgery. The purpose of this research is to develop a series of training exercises based on virtual reality using HTC Vive headset to emulate real-world training of doctors. This virtual training not only gives the trainee doctors mastery in More >

Abstract Introduction: We compared the return-to-work interval (RTWI) after radical retro-pubic prostatectomy (RRP) and robot-assisted laparoscopic prostatectomy (RALP) in men being treated for early-stage prostate cancer.
Materials and methods: We mailed a 28-item questionnaire to a random sample of 2,696 patients who either had RRP from 1995 to 2004 or RALP from 2004 to 2011.
Results: We received analyzable questionnaires from 315 patients; 178 had RALP and 137 had RRP. The median RTWI was shorter in the RALP group than in the RRP group (3 versus 4 weeks, p = .016). The percent of subjects who had not returned More >

Abstract Introduction: Renal duplication is a relatively common congenital abnormality of the urinary tract, but symptomatic duplex kidney is a rare presentation in adults. Traditionally, the treatment of choice for poorly functioning moiety has been heminephrectomy. There is extensive literature detailing the outcomes of minimally invasive upper pole heminephrectomy, but comparatively little published regarding lower pole resection, especially in adult patients. We present a series of 13 patients who underwent minimally invasive heminephrectomy for duplex kidney.
Materials and methods: Over a 6-year period (2011-2017), 13 patients at a single center underwent laparoscopic heminephrectomy for symptomatic duplex kidney with… More >
