ABSTRACT
Interventional radiology is a new medical specialty that recently created an integrated residency. This study serves a comprehensive review of literature discussing the challenges that medical students encounter in light of this new pathway, with a specific emphasis on the virtual application process. An analysis of 24 articles revealed that exposure to interventional radiology in medical school is lacking, with a limited pool of diverse mentors in the field. Moreover, medical school advising to students applying to interventional radiology may be inadequate. Although initiatives have been successful in increasing exposure, and there is encouraging data on diversity in the field at the trainee level since the start of the integrated residency, addressing the needs of medical students and focusing on the gaps in mentorship, advising, and curriculum is crucial for the success of applicants and overall specialty recruitment. The virtual process has provided on average $6008 of savings for applicants.

PURPOSE: Preservation of renal parenchyma is a major goal when performing a partial nephrectomy. IRIS anatomical visualization software generates a segmented 3D model, allowing improved visualization of the tumor and surrounding structures. We hypothesize that using IRIS intraoperatively during partial nephrectomy on complex tumors increases the precision of surgical procedures and therefore may result in more tissue preservation. METHODS: We identified 74 non-IRIS and 19 IRIS patients who underwent partial nephrectomy, with nephrometry scores of 9, 10, and 11. Propensity scores were used to match 18 pairs of patients on nephrometry score, age, and tumor volume. Pre- and postoperative imaging (MRI/CT) was obtained. Volumes of the preoperative tumor and preoperative whole kidney were obtained to calculate predicted postoperative whole kidney volume and then compared to actual postoperative whole kidney volume. RESULTS: Mean differences between predicted and actual postoperative whole kidney volumes were 19.2 cm3 (SD=20.2) and 32 cm3 (SD=16.1, P = .0074) for IRIS and non-IRIS groups, respectively. The mean improvement in precision for the IRIS procedure was 12.8 cm3 (95% confidence interval, 2.5 to Inf; P = .02). There was no significant change in mean glomerular filtration rate from baseline to 6 months postoperatively between IRIS and non-IRIS groups (-6.39, SD=15.8 vs -9.54, SD=13.3; P = .5). No significant differences in complication rates (0 vs 1, P = .2), worsening glomerular filtration rate staging (5 vs 4, P = 1), and >25% decrease in glomerular filtration rate (3 vs 4, P = 1) were found between IRIS and non-IRIS groups. CONCLUSIONS: We demonstrated that using IRIS intraoperatively when performing partial nephrectomy on complex tumors is associated with improved surgical precision.

The objective of this study was to compare the perioperative and short-term functional and oncological outcomes of single-port and multiport robotic-assisted laparoscopic partial nephrectomy using propensity-score analysis. We evaluated all patients who underwent robotic partial nephrectomy at our institution between January 2019 and October 2020. Patient demographics, intraoperative data, and postoperative outcomes were collected and analyzed. Propensity-score matching was performed on age, sex, body mass index, prior abdominal surgery, and nephrometry score using the optimal matching method. A post hoc sensitivity analysis was performed to examine the robustness of the results. In total, 48 and 238 patients underwent single-port and multiport robotic partial nephrectomy, respectively. Following propensity-score matching, 48 multiport cases were matched 1:1 to single-port cases. The single-port cohort had lower median opioid use at postoperative day 1 (4.6 vs 9.8 MME, p = 0.0209) and cumulative hospital stay (5.1 vs 9.3 MME, p = 0.0357). Single port also had a shorter median length of stay (1.4 vs 1.6 days, p = 0.0045), although the post hoc sensitivity analysis showed no difference between the groups [- 0.13 (95% CI; - 0.580, 0.315, p = 0.5607). There were no significant differences in operative time, estimated blood loss, ischemia time, transfusions received, or positive margin rates. In conclusion, based on our early experience, single-port robotic partial nephrectomy is a safe and acceptable alternative to multiport robotic partial nephrectomy, providing comparable perioperative and postoperative outcomes while reducing inpatient opioid use.

OBJECTIVES: To compare the perioperative and postoperative outcomes of single port (SP) robotic pyeloplasty and multiport (MP) robotic pyeloplasty using a propensity-score matched analysis. MATERIALS AND METHODS: We performed a chart review of all patients who underwent SP robotic pyeloplasty from January 2019 to October 2020 and MP robotic pyeloplasty from January 2016 to October 2020. Patient demographics, intraoperative data, and postoperative outcomes were collected and analyzed. Propensity-score matching was performed on sex, body mass index, and history of previous pyeloplasty to adjust for potential baseline confounders. A post hoc sensitivity analysis for operative time was performed to examine the robustness of the results. RESULTS: In total, 24 and 41 patients underwent sSP and MP robotic pyeloplasty, respectively. Following propensity-score matching, 21 MP cases were matched 1:1 to SP cases. The SP group was shown to have longer median operative times (128.0 vs 88.0 minutes, Pâ¯=â¯.0411) and shorter follow up time (9.3 vs 18.7 months, Pâ¯=â¯.0066). In a sensitivity analysis, SP robotic pyeloplasty was marginally associated with increased operative time (95% CI -0.25, 29.72, Pâ¯=â¯.0540). CONCLUSIONS: SP robotic pyeloplasty is a safe and acceptable alternative to MP robotic pyeloplasty, achieving comparable perioperative and postoperative outcomes.

High-frequency repeated transcranial magnetic stimulation (HF-rTMS) is a safe non-invasive neuromodulatory technique and there is a body of evidence shows that it can modulate plasticity in different brain areas. One of the most interesting application of HF-rTMS is the modulation of plasticity in primary motor cortex (M1) to promote recovery after brain injuries. However, the underlying mechanism by which HF-rTMS modulates motor cortex plasticity remain to be investigated. In this study, we investigated the effects of HF-rTMS treatment on morphological plasticity of pyramidal neurons in layer II/III (L2/3) of the primary motor cortex in mice. Our results show that the treatment did not increase anxiety in mice in the open field test and the elevated plus-maze test. Treated mice displayed increased total spine density in apical and basal dendrites, with a predominance of thin spines. The treatment also increased dendritic complexity, as assessed by Sholl analysis at both apical and basal dendrites. Collectively, the results show that HF-rTMS induced remarkable changes in dendritic complexity in primary motor cortex L2/3 connections which may strengthen corticocortical connections increasing integration of information across cortical areas. The data support the use of HF-rTMS as a circuit-targeting neuromodulation strategy.
