Abstract
Background The nephrometry scoring system plays a key role in the preoperative evaluation of partial nephrectomy, and scoring systems based on anatomical characteristics have high similarity in scoring elements. Currently, there is little research on scoring systems related to retroperitoneal laparoscopic partial nephrectomy, and there is a lack of research on the combination of scoring elements, which requires further investigation. Methods We retrospectively analyzed the clinical records of 107 patients who underwent retroperitoneal laparoscopic partial nephrectomy conducted by a single operator at a single center. The score and scoring elements were generated based on imaging. The scoring elements of each scoring system and all combinations of two to five elements were extracted. The predictive ability of different score combinations was evaluated by AUC value, and the key parameters of the score were found by taking the intersection. A nomogram was constructed and evaluated. Results We observed that with an increase in scoring elements, the strongest combination of elements did not significantly increase the predictive ability of warm ischemia time (P>0.05), postoperative complications (P>0.05), and trifecta achievement (P>0.05). The combination of the maximum tumor diameter and the distance between tumor and collecting system or renal sinus had a good comprehensive predictive ability, and there is no significant difference with the traditional score (P>0.05). The nomogram generated according to this combination has an excellent prediction ability for predicting whether obtain trifecta of partial nephrectomy. Conclusions Within the range of two to five elements, the critical degree of elements is more important than the number of elements. The maximum tumor diameter and the distance between the tumor and the collecting system or renal sinus was the key element of the prediction ability.

Assessing Trifecta Achievement after Percutaneous Cryoablation of Small Renal Masses: Results from a Multi-Institutional Collaboration. MEDICINA (KAUNAS, LITHUANIA) 2022; 58:medicina58081041. [PMID: 36013508 PMCID: PMC9412454 DOI: 10.3390/medicina58081041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Revised: 07/28/2022] [Accepted: 08/01/2022] [Indexed: 11/17/2022]
Abstract
Background and Objectives: To assess efficacy and safety of Percutaneous Cryoablation (PCA) of small renal masses (SRMs) using Trifecta outcomes in a large cohort of patients who were not eligible for surgery. Materials and methods: All PCAs performed in four different centers between September 2009 and September 2019 were retrospectively evaluated. Patients were divided in two different groups depending on masses dimensional criteria: Group-A: diameter ≤ 25 mm and Group-B: diameter > 25 mm. Complications rates were reported and classified according to the Clavien−Dindo system. The estimate glomerular filtration rate (eGFR) was calculated before PCA and during follow-up schedule. Every patient received a Contrast Enhanced Ultrasound (CEUS) evaluation on the first postoperative day. Radiological follow-up was taken at 3, 6, and 12 months for the first year, then yearly. Radiological recurrence was defined as a contrast enhancement persistence and was reported in the study. Finally, Trifecta outcome, which included complications, RFS, and preservation of eGFR class, was calculated for every procedure at a median follow-up of 32 months. Results: The median age of the patients was 74 years. Group-A included 200 procedures while Group-B included 140. Seventy-eight patients were eligible for Trifecta evaluation. Trifecta was achieved in 69.6% of procedures in Group-A, 40.6% in Group-B (p = 0.02). We observed an increased rate of complication in Group-B (13.0% vs. 28.6; p < 0.001). However, 97.5% were <II Clavien−Dindo grade. No differences were found between the two groups regarding eGFR before and after treatment. Further, 24-months RFS rates were respectively 98.0% for Group-A and 92.1% in Group-B, while at 36 months were respectively 94.5% and 87.5% (p = 0.08). Conclusions: PCA seems to be a safe and effective treatment for SRM but in the need of more strict dimensional criteria to achieve a higher possible success rate.

Predicting Strict Trifecta Outcomes after Robot-Assisted Partial Nephrectomy: Comparison of RENAL, PADUA, and C-Index Scores. J Kidney Cancer VHL 2021; 8:1-12. [PMID: 34703725 PMCID: PMC8490181 DOI: 10.15586/jkcvhl.v8i4.183] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2021] [Accepted: 09/03/2021] [Indexed: 01/20/2023] Open
Abstract
Nephrometry scores are designed to characterize tumors and stratify the surgical complexity. It remains unclear as to which nephrometry score can accurately predict the surgical outcomes. We aimed to assess the utility of radius, exophytic/endophytic, nearness, anterior/posterior, location (RENAL), preoperative aspects and dimensions used for anatomic classifications (PADUA), and centrality index (C-index) nephrometry scores for predicting the strict Trifecta achievement from a single institution series robotic-assisted partial nephrectomy (RAPN). We retrospectively identified the prospectively maintained robotic surgery database records of 91 patients who underwent RAPN between June 2015 and September 2020 in Antalya Training and Research Hospital. The main outcome of the study was the achievement of strict Trifecta (negative surgical margin, no major urologic complications, warm ischemia time ≤25 min, and ≥85% preservation of estimated glomerular filtration rate). A multivariable analysis was performed to identify the factors of strict Trifecta success. The mean patient age was 55.82 ± 13.37 years with a median clinical tumor size of 3.5 cm (IQR 2.5–4.9). The median RENAL, PADUA, and C-index score were 7(IQR 6–8), 8(IQR 7–10), and 2.01(IQR 1.64–2.72), respectively. A strict Trifecta could be achieved in 54 patients (59.3%). Clinical tumor size (P = 0.011), RENAL risk groups (low:reference; intermediate; P = 0.040; high; P = 0.009), PADUA risk groups (low:reference; intermediate; P = 0.044; high; P = 0.001) and C-index risk groups (low:reference; high; P = 0.015) were the independent predictors of strict Trifecta attainment in the multivariate analysis. None of the nephrometry scores were a superior predictor compared to other nephrometry scores in comparative analysis. RENAL, PADUA, and C-index scores were all independent predictors of a strict Trifecta achievement. Our comprehensive comparison of the three scores identified that none of the nephrometry scores proved to be inferior to others nephrometry scores.

Abstract
INTRODUCTION This study aimed to evaluate the chronologic changes in renal function after laparoscopic partial (LPN) or radical nephrectomy (LRN) in patients with clinical T1 renal cell carcinoma. METHODS In this retrospective study, patients with clinical stage T1 renal cell carcinoma who underwent LPN or LRN were divided into three groups, namely, LPN-A group including LPN patients with WIT ≤25 minutes, LPN-B group including LPN patients with WIT >25 minutes, and LRN group. Perioperative complications that occurred within 30 days after surgery were retrieved. All patients were followed-up every 3 months to evaluate the estimated glomerular filtration rate. The primary endpoint of this study was to assess the chronological changes in renal function after surgery. RESULTS A total of 153 patients were enrolled in this study. The change in estimated glomerular filtration rate between day 1 and 2 weeks after surgery was significantly lower in the LPN-B group than in the LPN-A group (p<0.005). Both LPN-A and -B groups achieved eGFR ≥90% 2 weeks after surgery. In addition, the estimated glomerular filtration rate decline from post-operative day 1 through 24 months in the LPN-A group or the LPN-B group was significantly smaller than that in the LRN group (P < 0.001, P < 0.001, respectively). CONCLUSION Our results demonstrate the efficacy and safety of LPN in patients with T1 renal cell carcinoma. Although complication rates were similar in both groups, post-operative renal function was not different between the LPN-A and -B groups.

Abstract
PURPOSE The predictors of trifecta achievement in partial nephrectomy (PN) were poorly inquired and remained a controversial area of discovery. To evaluate predictive factors of trifecta achievement in patients undergoing PN. MATERIALS AND METHODS A systematic literature search was performed to identify relevant articles. Only studies focusing on postoperative trifecta achievement and exploring its predictor with multivariable analyses were included. The trifecta achievement was defined as negative surgical margins, warm ischemia time <25 minutes, and no complications. Merged odds ratio (OR) and 95% confidence interval (CI) were used to evaluate the predictive effect. RESULTS Thirteen studies with 7066 patients meeting the inclusion criteria were included. The rate of trifecta achievement ranged from 43.3% to 78.6%. Merged results showed that preoperative eGFR (OR: 1.01, 95% CI: 1.00, 1.02, P=0.02), operative time (OR: 0.99, 95% CI: 0.99, 1.00, P=0.02), estimated blood loss (OR: 1.00, 95% CI: 1.00, 1.00, P <0.001), tumor size (OR: 0.70, 95% CI: 0.58, 0.84, P <0.001), medium (OR: 0.39, 95% CI: 0.18, 0.84, P=0.02) and high PADUA score (OR: 0.23, 95% CI: 0.08, 0.64, P=0.005) were independently associated with trifecta achievement. A publication bias was identified for tumor size. Sensitivity analysis confirmed the stability of result for tumor size. CONCLUSIONS Larger tumor size, medium and high PADUA score are associated with decreased probability of trifecta achievement. After verifying by further high-quality studies, these variables can be incorporated into tools to predict probability of trifecta achievement during clinical practice.

Abstract
INTRODUCTION The goal of partial nephrectomy for renal tumors is complete tumor removal with the preservation of renal function and no complications. Trifecta (total ischemia time < 25 minutes, negative surgical margins, and no surgical complications) is widely used to evaluate success after partial nephrectomy. We investigated factors affecting renal function preservation among patients not achieving trifecta after laparoscopic partial nephrectomy. METHODS Sixty-six patients who underwent laparoscopic partial nephrectomy for clinical T1a renal masses between December 2006 and March 2016 were examined. We defined preserved renal function as the preservation of an estimated glomerular filtration rate ≥ 90% 1 year after surgery. We examined factors affecting renal function preservation among patients not achieving trifecta after laparoscopic partial nephrectomy. RESULTS Thirty out of 66 patients (45%) did not achieve trifecta. In an evaluation of 66 patients, a multivariate analysis identified tumor size (P = .04) as an independent predictor affecting the achievement of trifecta. Tumor size was significantly smaller in the trifecta achievement group (1.9 ± 0.1 cm) than in the non-achievement group (2.2 ± 0.6 cm) (P = .04). We found that renal function was preserved 1 year after surgery in 14 out of the 30 patients not achieving trifecta. In univariate analysis, age (P = .01) was significantly associated with affecting the preservation of renal function among these patients. Patients with preserved renal function were significantly younger (47.8 ± 2.5 years) than those without (58.5 ± 2.9 years) (P = .01). CONCLUSION Renal function may be preserved in younger patients even if they do not achieve trifecta after partial nephrectomy for small renal masses.

Achieving the "trifecta" with open versus minimally invasive partial nephrectomy. World J Urol 2020; 39:1569-1575.

Abstract
INTRODUCTION The "trifecta" is a summary measure of outcome after partial nephrectomy (PN) that encompasses three parameters: negative surgical margin, ≤ 10% decrease in post-operative estimated glomerular filtration rate (eGFR) and absence of urological complications. We assessed trifecta rates in patients undergoing open (OPN), laparoscopic (LPN), and robotic PN (RPN) for a clinical T1 renal mass (≤ 7 cm). METHODS Clinical and pathologic parameters were extracted from the prospectively maintained Canadian Kidney Cancer Information System for patients treated between January 2011 and October 2018. Comparisons between groups were made using Kruskal-Wallis test for continuous variables and Chi-squared independence test for categorical variables. Multivariable analysis was performed to identify predictors of each component of the trifecta and the trifecta itself. RESULTS Of 1708 total patients, 746 underwent OPN, 678 LPN, and 284 RPN for a T1 renal mass. A 'trifecta' was achieved in 53% OPN, 52% LPN and 47% RPN (p = 0.194). On multivariable analysis, OPN and LPN were associated with less frequent post-operative decline in eGFR and more frequent trifecta when compared to RPN, but there was no difference between OPN and LPN. OPN also predicted a higher rate of negative margins compared to RPN but not LPN. CONCLUSION After correction for confounding variables, OPN and LPN were more likely than RPN to achieve the trifecta, which appeared to be due primarily to loss of renal function. No difference was observed between OPN and LPN. Analyses were limited by the lack of nephrometry score.

Abstract
OBJECTIVES To evaluate the outcomes of robotic partial nephrectomy compared with those of laparoscopic partial nephrectomy for T1 renal tumors in Japanese centers. METHODS Patients with a T1 renal tumor who underwent robotic partial nephrectomy were eligible for inclusion in the present study. The primary end-point consisted of three components: a negative surgical margin, no conversion to open or laparoscopic surgery and a warm ischemia time ≤25 min. We compared data from these patients with the data from a retrospective study of laparoscopic partial nephrectomy carried out in Japan. RESULTS A total of 108 patients were registered in the present study; 105 underwent robotic partial nephrectomy. The proportion of patients who met the primary end-point was 91.3% (95% confidence interval 84.1-95.9%), which was significantly higher than 23.3% in the historical data. Major complications were seen in 19 patients (18.1%). The mean change in the estimated glomerular filtration rate in the operated kidney, 180 days postoperatively, was -10.8 mL/min/1.73 m2 (95% confidence interval -12.3-9.4%). CONCLUSIONS Robotic partial nephrectomy for patients with a T1 renal tumor is a safe, feasible and more effective operative method compared with laparoscopic partial nephrectomy. It can be anticipated that robotic partial nephrectomy will become more widely used in Japan in the future.

Abstract
INTRODUCTION Elderly patients represent a growing part of our society for who treatment strategy for localized renal tumors has to be chosen knowing iatrogen effects and renal function morbidity. The aim was to analyze oncological and functional results of nephron sparing surgery (PN) versus radiofrequency ablation (RFA). MATERIALS AND METHODS All patients aged more than 75 treated by partial nephrectomy or radiofrequency ablation between 2007 and 2014 in our centre were included. Patient and tumors data were compared and these criteria were analyzed: survival (overall and without recurrence) and loss of renal function (pre- and postoperative MDRD). RESULTS In total, 100 patients were included (26 partial nephrectomies, group 1 and 74 radiofrequency ablation, group 2) with a 32-months medium follow-up. Medium age and tumor size were significantly different (respectively, 78 versus 81 years old, P=0.001, 38mm versus 29mm, P=0.003). Perioperative results showed no differences in complications. Transfusion rate and duration of hospital stay were significantly higher in the PN group. Median overall survival were 45 vs. 27 months (P=0.23) for PN and RFA and median recurrence-free survival were 28 vs. 10 months (P=0.34). On a multivariate analysis, operative technique (PN or RFA) were not significantly linked to survival (HR 2.37 [95% CI: 0.66-8.5]), P=0.19. Loss of renal function were 1.5±14mL/min/1.73m2 for PN and 3±14mL/min/1.73m2 for RFA (P=0.69). CONCLUSION Our study showed better perioperative results for RFA than for PN, without significant different survival. Loss of renal function were little and similar. LEVEL OF EVIDENCE 4.

PLoS One 2017; 12:e0180515.

Abstract
Purpose Although laparoscopic Heller myotomy and Dor fundoplication (LHD) is widely performed to address achalasia, little is known about the learning curve for this technique. We assessed the learning curve for performing LHD. Methods Of the 514 cases with LHD performed between August 1994 and March 2016, the surgical outcomes of 463 cases were evaluated after excluding 50 cases with reduced port surgery and one case with the simultaneous performance of laparoscopic distal partial gastrectomy. A receiver operating characteristic (ROC) curve analysis was used to identify the cut-off value for the number of surgical experiences necessary to become proficient with LHD, which was defined as the completion of the learning curve. Results We defined the completion of the learning curve when the following 3 conditions were satisfied. 1) The operation time was less than 165 minutes. 2) There was no blood loss. 3) There was no intraoperative complication. In order to establish the appropriate number of surgical experiences required to complete the learning curve, the cut-off value was evaluated by using a ROC curve (AUC 0.717, p < 0.001). Finally, we identified the cut-off value as 16 surgical cases (sensitivity 0.706, specificity 0.646). Conclusion Learning curve seems to complete after performing 16 cases.

The impact of gender difference on operative time in laparoscopic partial nephrectomy for T1 renal tumor and the utility of retroperitoneal fat thickness as a predictor of operative time. BMC Cancer 2016; 16:944. [PMID: 27955631 PMCID: PMC5154121 DOI: 10.1186/s12885-016-2979-5] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2016] [Accepted: 11/29/2016] [Indexed: 01/20/2023] Open
Abstract
BACKGROUND To investigate the impact of biological gender on operative parameters, especially operative time, in laparoscopic partial nephrectomy (LPN) for T1 renal tumor. METHODS One hundred and eleven (28 female and 83 male) patients and 64 (20 female and 44 male) patients with renal tumors suspected to be RCC cT1aN0M0 who underwent retroperitoneal and transperitoneal LPN, respectively, were analyzed. The influence of sex on operative factors including retroperitoneal fat tissue thickness, determined on CT, was analyzed. The correlation between operative time and gender was evaluated by unpaired t-test and linear logistic regression model. RESULTS In both retroperitoneal and transperitoneal LPN, the retroperitoneal fat tissue thickness was greater in men than in women. In retroperitoneal LPN, the operative time was significantly longer in men than in women. In contrast, in transperitoneal LPN, no gender difference was observed in regard to the operative time. In retroperitoneal LPN, linear logistic regression assessment showed that gender, retroperitoneal fat tissue thickness, and tumor size were significantly associated with operative time. Coefficient of determination of the prediction model was 0.317. CONCLUSIONS The operative time of retroperitoneal LPN is significantly correlated with gender, maximum tumor diameter, and retroperitoneal fat tissue thickness. We have developed a prediction model for the operative time of retroperitoneal LPN based on preoperative parameters. Interestingly, in transperitoneal LPN, a gender difference in operative time was not apparent, and also predicting operative time might be difficult.

Perioperative and renal functional outcomes of laparoscopic partial nephrectomy (LPN) for renal tumours of high surgical complexity: a single-institute comparison between clampless and clamped procedures. World J Urol 2016; 35:403-409. [PMID: 27324881 DOI: 10.1007/s00345-016-1882-7] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2016] [Accepted: 06/10/2016] [Indexed: 01/20/2023] Open
Abstract
PURPOSE In recent times there has been a trend in mininvasive renal tumour surgery. Very limited evidence can be found in literature of the outcomes of laparoscopic partial nephrectomy (LPN) for highly complex renal tumours. The aim of the present study was to assess the feasibility and safety of LPN for renal tumours of high surgical complexity in our single-institutional experience, comparing perioperative and functional data between clampless and clamped procedures. MATERIALS AND METHODS We enrolled 68 patient who underwent a clampless LPN (Group A) and 41 patients who underwent a clamped LPN (Group B) for a renal tumour with a R.E.N.A.L. NS ≥ 10. Intraoperative and post-operative complications have been classified and reported according to international criteria. Kidney function was evaluated by measuring serum creatinine concentration and eGFR. RESULTS Group A was found to be similar to Group B in all variables measured except for WIT (P = 0) and blood loss (P = 0.0188). In group A the mean creatinine levels were not significantly increased at the third post-operative (P = 0.0555) day and at the 6-month follow-up (P = 0.3047). Otherwise, in the group B the creatinine levels were significantly increased after surgery (P = 0.0263), but decreased over time, showing no significant differences at 6 month follow-up (P = 0.7985) compared to preoperative values. The same trend was seen for eGFR. Optimal Trifecta outcomes were achieved in both groups. CONCLUSIONS Clampless LPN represents a feasible and safe procedure, even for tumours with high surgical complexity, in highly experienced laparoscopic centers. When compared to clamped LPN, it results in better preservation of immediate post-operative renal function.
