Does Incision Location Matter? Analysis of Single-Port Cosmesis in Urologic Reconstructive Surgery.

Introduction and Objective: One potential advantage of single-port (SP) robotic surgery compared with multiport (MP) robotic surgery is improved cosmesis. The only studies in urology patients to suggest this finding did not assess differences based on incision site. Our study evaluated SP, MP, incision location, age, gender, and prior abdominal surgery as predictors of cosmesis and scar consciousness for reconstructive procedures. Methods: This is a cohort study using an institutional review board-approved prospective genitourinary reconstruction database. Patients at least 3 months from surgery were emailed and called to complete the Consciousness subsection of the Patient Scar Assessment Questionnaire. Bothersome was defined as a score of 11 or greater. Overall consciousness was scored with a single item as "not conscious" or "conscious." Pearson's chi-squared, Wilcoxon rank sum, Fisher's exact test, and logistic regression were performed to assess how age, gender, prior surgery, and incision location affect cosmesis. Results: There were 111 patients (54 MP, 57 SP), of which 27 were SP umbilical, 14 were SP midline nonumbilical, and 16 were SP lower quadrant. On univariate analysis the periumbilical incision had the lowest consciousness. Age was associated with Bother (p = 0.012) and Consciousness (p = 0.002), whereas gender, prior abdominal surgery, and incision site were not significant. On logistic regression, all SP incisions were less likely to be bothered compared with MP, although only SP umbilical was statistically significant (odds ratio [OR] = 0.08, 95% confidence interval [CI]: 0.01,0.38; p = 0.005). Age was also significant on logistic regression for Bother (OR = 0.96, 95% CI: 0.93,0.99; p = 0.005). Gender and prior abdominal surgery were not associated with Bother or Consciousness. Conclusions: SP periumbilical incisions provide the best outcomes for cosmesis compared with other SP incision sites and MP incisions. This finding should be discussed and taken into account when planning surgical approaches for patients undergoing urinary reconstruction, especially in patients younger than 40 years of age.

Race-modified estimated glomerular filtration rate underestimates chronic kidney disease prevalence in Black patients undergoing partial and radical nephrectomy: Implications for surgical planning.

Introduction: In estimated glomerular filtration rate equations (eGFR), the race multiplier (RM) yields greater eGFR values and may assign less severe chronic kidney disease (CKD) stages to black individuals. When deciding on appropriateness for partial nephrectomy (PN), patients with CKD are often considered a relative or absolute indication. We hypothesize that the eGFR RM may have ramifications for patients being counseled for radical nephrectomy (RN) versus PN to manage their renal tumor. Methods: We utilized prospective and retrospective, IRB-approved single-center databases to select patients who underwent PN or RN between 2016 and 2022. Demographics, preoperative risk factors, preoperative eGFR, and surgical management were collected. Descriptive statistics and two-tailed difference of proportion tests compared the percentage of patients with CKD who underwent nephrectomy. Results: This cohort included 1137 patients who underwent RN or PN, including 74 (6.5%) Black patients and 93.5% (n = 1063) non-Black patients. There was no statistically significant difference between the eGFR of Black and non-Black individuals using the Modification of Diet in Renal Disease equation (P = 0.24) or Chronic Kidney Disease Epidemiology Collaboration 2009 (CKD-EPI 2009) (P = 0.45); however, there was statistically significant difference in eGFR between sample populations when using CKD-EPI 2021 (P = 0.0055). Of the Black patient cohort, 16.2% of patients reclassified to a worse CKD class using CKD-EPI 2021, including 9.5% of Black patients reclassified to CKD3a or worse, and 14.6% of all patients (Black and non-Black) reclassified to a different CKD class under the CKD-EPI 2021 equation. Conclusions: There are quantitative differences in the evaluation of eGFR when utilizing different equations that may impact clinical considerations and health equity outcomes for nephrectomy across racial groups.

Incidental prostate carcinoma after single-port robot-assisted simple prostatectomy: a multi-institutional report (SPARC).

BACKGROUND: Single-port robot-assisted simple prostatectomy is a minimally invasive alternative for patients with large benign prostatic hyperplasia with severe symptoms and/or failure of medical treatment. In recent literature, the rate of incidental prostate cancer after simple prostatectomy ranges from 1.8% to 13.0%. Our objective is to report the rate of incidental prostate cancer after single-port robot-assisted simple prostatectomy and to compare our findings to other approaches. METHODS: A Single-Port Advanced Research Consortium [SPARC] multi-institutional retrospective analysis of all initial consecutive single-port robot-assisted simple prostatectomy cases performed from 2019 to 2023 by eleven surgeons from six centers. Our primary outcome was the rate of incidental prostate cancer in adenoma specimens. We used descriptive statistics to analyze the data. RESULTS: A total of 235 cases were performed successfully without conversions or additional ports. Eleven patients (4.6%) were found to have incidental prostate cancer on pathological analysis. The median percentage of tissue involved by the tumor was 5%. The overall rate of clinically significant prostate cancer was 2.1%. Most cases were Gleason Grade Group 1 (55%). Those with Grade Group ≤3 were subsequently managed with active surveillance with a median follow-up of 17 months. A patient with Gleason Grade Group 4 underwent an uncomplicated multi-port robot-assisted radical prostatectomy with satisfactory functional and oncological outcomes. CONCLUSIONS: Initial multi-institutional experience with single-port robot-assisted simple prostatectomy showed an incidental prostate cancer rate of 4.6%, comparable to MP, laparoscopic, and open techniques.

IVC thrombectomy and atrial tumor removal with radical nephrectomy and adrenalectomy for metastatic melanoma with immune checkpoint inhibitor therapy: A case report and literature review.

Caval thrombus with intracardiac involvement is a rare condition that is associated with renal cell carcinoma. Few reports in literature describe this presentation with metastatic melanoma. Metastatic melanoma is known to involve the adrenal gland, although associated tumor thrombus extension into the renal vein and inferior vena cava is extremely rare. In this case report, we describe radical nephrectomy and adrenalectomy for metastatic melanoma.

Single institution series describing external ventricular drain (EVD) placement and short- and long-term complications related to placement accuracy.

Background: The placement of an external ventricular drain (EVD) for the treatment of acute hydrocephalus is one of the most common life-saving procedures that neurosurgeons perform worldwide. There are many well-known complications associated with EVD placement, including tract hemorrhages, intra-parenchymal and subdural hemorrhages, infection, and catheter misplacement. Given the variety of complications associated with EVD placement and the inconsistent findings on the relationship of accuracy to complications, the present study reviewed short- and long-term complications related to EVD placement at our institution. Methods: A retrospective review was conducted for all consecutive patients who underwent bedside EVD placement for any indication between December 2020 and December 2021. Collected variables included demographic information, etiology of disease state, pre-and post-operative head computed tomography measurements, and post-procedural metrics (immediate and delayed complications). Results: A total of 124 patients qualified for inclusion in our study. EVDs that were non-functioning/exchanged were not significantly related to age, accuracy, ventriculomegaly, sex, disposition, laterality, type of EVD used, intraventricular hemorrhage (IVH), etiology, or Kakarla Grade (KG) (all P > 0.17). The need for a second EVD was similarly not related to age, accuracy, ventriculomegaly, sex, disposition, location, laterality, type of EVD used, IVH, etiology, or KG (all P > 0.130). Patients who died, however, were significantly more likely to have a second contralateral EVD placed (18.2% vs. 4.9% P = 0.029). We also found that left-sided EVDs were significantly more likely to fail within seven days of placement (29.4% vs 13.3%, P = 0.037; relative risk (RR) 1.93, 95% confidence interval: 1.09-3.43), unrelated to age, sex, etiology, type of EVD, IVH, location of the procedure, or accuracy (all P > 0.07). This remained significant when using a binary logistic regression to control for ventriculomegaly, accuracy, mortality, age, sex, and etiology (P = 0.021, B = 3.43). Conclusion: In our cohort, although a clear relationship between inaccuracy and complication rates was not found, our data did demonstrate that left-sided EVDs were more likely to fail within the immediate postoperative time point, and patients who died were more likely to have a second, contralateral EVD placed.

Single Port Modified Partial Nephrectomy: Novel Simultaneous Access to Peritoneal and Retroperitoneal Partial Nephrectomy, Initial Clinical Experience.

Introduction and Objective: Since its Food and Drug Administration (FDA) approval in 2018, Intuitive Surgical DaVinci single port (SP) robotic platform has been an effectively used technology for multiple urologic procedures. The purpose of this study is to share our early intraoperative and perioperative outcomes and potential benefits for performing a lower anterior access (LAA) incision for SP robot-assisted partial nephrectomy (SP-RAPN). The LAA incision enables performing a trans- or retroperitoneal (RP) approach through the same incision and eases the transition to a RP approach. Methods: This study is a prospective review of 78 SP-RAPN cases between March 2021 and January 2023 by an experienced robotic surgeon. A single 2-3 cm oblique incision parallel to the external oblique muscle, one-third of the distance between the iliac crest and umbilicus, was used to insert the multichannel port to perform the RAPN. We extracted intra- and perioperative data of these patients to share the outcomes of this approach. Results: SP-RAPN was effectively completed in 78 patients (38 females and 40 males) without conversion to open or laparoscopic techniques. The mean age was 61.2 ± 12.1 years. The mean tumor size was 3.0 ± 1.2 cm, 43 were right-sided masses, and 35 were left sided. The R.E.N.A.L Nephrometry score ranged from (4-11) with an average of 7.0 ± 1.9. Average operating room time was 90.5 ± 24.6 minutes, estimated blood loss was 88.3 ± 134 mL, and length of stay of 1.07 ± 0.7 days. Of the 78 cases, 40 required clamping of the renal artery with average warm ischemia time of 19.4 ± 6.7 minutes in patients who underwent clamping. No complications in all of 78 patients. Conclusions: This study demonstrates the feasibility and reproducibility of SP-RAPN using a LAA incision. This incision provides a standardized approach for surgeons to transition to the RP approach using the SP platform.

Preoperative Predictors of Surgical Success for Robotic Ureteral Reconstruction of Proximal and Middle Ureteral Strictures.

OBJECTIVE: To investigate predictors of surgical success for patients undergoing robotic ureteral reconstruction (RUR) for ureteropelvic junction obstruction (UPJO), proximal, and middle ureteral stricture disease. METHODS: We retrospectively reviewed our multi-institutional Collaborative of Reconstructive Robotic Ureteral Surgery database to identify all consecutive patients undergoing RUR for UPJO, proximal and/or middle ureteral stricture disease between April 2012 and December 2020. The specific reconstruction technique was determined by the primary surgeon based on clinical history and intraoperative findings. Patients were grouped according to whether they were surgical successful. Preoperative variables between both groups were compared using chi-square tests. All independent variables with associations of P <.2 then underwent a binary logistic regression analysis to determine predictive variables of success for RUR (P ≤.05 was considered statistically significant). RESULTS: Overall, 338 patients met inclusion criteria. Surgical success rates of RUR are shown in Table 1. Univariate analysis (Table 2) showed that there were a lower proportion of patients with diabetes (8.9% vs 25.7%, P <.01) and a higher proportion of patients who underwent ureteral rest (74.3% vs 48.6%, P <.01) in the surgical success group. Multivariate logistic regression analysis (Table 3) further revealed the odds of surgical success in patients without diabetes was 3.08 times ((confidence interval) CI 1.26-7.54, P = .01) the odds of success for patients with diabetes. The odds of surgical success in patients who underwent preoperative ureteral rest were 2.8 times (CI 1.35-5.83, P = .01) the odds of success for patients who did not undergo preoperative ureteral rest. CONCLUSION: Surgical success of RUR for management of UPJO, proximal, and middle ureteral strictures may be influenced by factors including preoperative ureteral rest and presence of diabetes.

A Multipronged Intervention to Reduce Readmissions and Readmission Intensity After Radical Cystectomy.

OBJECTIVE: To develop a multipronged, evidence-based protocol to reduce readmission risk and readmission intensity, as represented by the duration of the index readmission, after radical cystectomy. MATERIALS AND METHODS: A per-protocol study was performed. The protocol included preoperative nutritional supplementation, early stent removal, and a follow-up phone call within 4-5days of discharge. The preprotocol period was from February 1, 2020 to July 31, 2021 and the postprotocol period was from December 1, 2020 to November 31, 2021. Using multivariate regression models, we compared outcomes among patients treated with radical cystectomy before and after protocol initiation. RESULTS: We identified 70 preprotocol patients and 126 postprotocol patients. After adjusting for age, sex, BMI, and frailty score, there was a significant reduction in 90-day readmission intensity (7 vs 5days; P = .048) among postprotocol patients. CONCLUSION: After implementation of an evidence-based protocol for patients undergoing radical 90-day readmission intensity decreased significantly. This protocol may move the needle forward on reducing readmissions, but a larger randomized trial is needed.

Evaluation of Alcohol Taxes as a Public Health Opportunity to Reduce Liver Transplant Listings for Alcohol-Related Liver Disease.

BACKGROUND: Alcohol-related liver disease (ALD) is a leading indication for liver transplantation. METHODS: State consumption of spirits, wine, and beer was determined from published sources. Excise and ad valorem alcohol taxes of spirits, wine, and beer were calculated following standard practices and correlated using multiple logistic regression models to 2002 to 2015 ALD transplant listing data from the United Network for Organ Sharing database. RESULTS: 21.22% (29,161/137,440) of transplant listings were for ALD. Increased consumption of spirits was associated with increased ALD transplant listings (odds ratio [OR]: 1.67; 95% CI: 1.12 to 2.49, p = 0.01), but wine and beer consumption did not have a statistically significant association with ALD transplant listings. Spirits excise taxes on- and off-premise were inversely associated with ALD transplant listing (OR: 0.79 and 0.82, respectively, both p < 0.02). Beer and wine taxes were not significantly associated with ALD transplant listings. CONCLUSIONS: Transplant listings for ALD are directly associated with spirit consumption and inversely associated with spirits excise taxes. These findings suggest a possible public health benefit of increasing excise taxes for spirits.

Patient Perspectives of High-Quality Care on the Liver Transplant Waiting List: A Qualitative Study.

The prevalence of advanced liver disease and listing for liver transplantation is increasing. Prior assessments of quality of care neither incorporate nor emphasize the patient perspective on quality of care, which may impact clinical outcomes. Our aim was to identify patients' perceptions on what constitutes high quality of care, comparing the findings to existing frameworks and assessments to determine if a patient-derived tool assessing quality of care could facilitate efforts to improve health care. We conducted semistructured interviews of patients wait-listed for liver transplantation, asking patients to describe the quality of their health care with a specific focus on how coordination, communication, office visits, hospitalizations, and cost affect their perceptions of the quality of their care. Data collection conducted concurrently with analyses determined emerging themes and saturation. Themes were mapped to an existing quality-of-care conceptual framework. Qualitative analysis revealed thematic saturation after 15 interviews, and an additional 15 interviews were analyzed that confirmed thematic saturation, maximizing the strength of the results. The 30 patients had a median age of 56 years (range, 32-72 years) and included 15 (50%) men. Although patients believed they received a high quality of care, which was substantiated on current existing measures, a qualitative analysis suggested that patient priorities emphasized 5 themes not currently assessed: managing expectations, providing education, responding to patient needs, executing the care plan efficiently, and utilizing interdisciplinary communication and coordination of care. In conclusion, transplant candidates perceived 5 themes that constitute quality of care, and existing quality-of-care measures do not assess these domains, suggesting a role for creating a patient-derived quality-of-care tool to improve health care and clinical outcomes.
