Pathological and clinical outcomes of adrenalectomy: A multi-center experience in Saudi Arabia.

Objective: To determine the nature of adrenal pathology in patients undergoing adrenalectomy in Saudi Arabia over the last decade and compare it with the literature. We compared perioperative outcomes between minimally invasive adrenalectomy (MIA) and open adrenalectomy (OA). Methods: This retrospective study included patients who underwent adrenalectomy at five tertiary care centers in Saudi Arabia from 2010 to 2020. We collected patients' baseline and perioperative characteristics and detailed hormonal evaluation of adrenal masses. Results: Among 160 patients (mean age 44 ± 14.5 years; mean BMI 29.17 ± 5.96 kg/m2), 84 (51.5 %) were men and 51.5 % had left-sided adrenal masses. The mean tumor size was 6.1 ± 4.2 (1.0-19.5) cm, including 60 (37.5 %) incidentalomas and 65 (40.6 %) functioning masses. Histopathology revealed 74 (46.2 %) adenomas and 24 (15 %) cancers or metastases from other primary organs; 20 %, 8.8 %, and 2.5 % of patients had pheochromocytoma, myelolipoma, and 2.5 % ganglioneuroblastoma, respectively. MIA and OA were performed in 135 (84.4 %) and 21 (15.6 %) patients, respectively. Adrenalectomy was increasingly performed over three equal periods in the last decade (17.5 % vs 34.4 % vs 48.1 %), with increasing numbers of MIAs to replace OAs. OA patients had larger tumors and needed blood transfusion more frequently (47.6 % vs 10.8 %, p< 0.001). MIA was significantly associated with shorter operative time, shorter length of stay, and less blood loss. Postoperative complications occurred in 10 (6.2 %) patients and were significantly higher for OA (24 % vs 3.0 %, p< 0.001). Conclusions: The majority of adrenal masses are benign. Herein, the observed functional and perioperative outcomes were comparable to those of available meta-analyses.

Creation and validation of the harmonized Arabic version of the Expanded Prostate Cancer Index Composite for Clinical Practice (EPIC-CP).

Objectives: Tocreate and validate a translated Arabic version of the Expanded Prostate Cancer Index Composite for Clinical Practice (EPIC-CP), a validated patient-reported outcome (PRO) widely used for assessing the quality of life in patients with prostate cancer (PCa). Patients and Methods: Using the established protocol as defined by the Professional Society for the Health Economics and Outcomes Research (ISPOR) for translating patient care questionnaires, a harmonised translated Arabic version of EPIC-CP was created. The questionnaire was tested in native Arabic speakers from four different Arabic countries (Saudi Arabia, United Arab Emirates, Jordan, and Kuwait). Cronbach's alpha and interclass coefficient correlation (ICC) analyses were used to test the internal consistency and test-retest reliability, respectively. In addition, PCa characteristics were collected for participants. Results: In total, 168 patients with PCa participated in the study (39 from Saudi Arabia, 23 from United Arab Emirates, 65 from Jordan, and 41 from Kuwait). In all, 52 (31%) participants repeated the questionnaire for test-retest reliability analysis. The median (interquartile range [IQR]) age of patients included in the study was 66 (61-71) years. The median (IQR) PSA level was 9.8 (6-19) ng/mL. Most patients had Grade Group 2 PCa at diagnosis (31%), clinical stage cT1 (42%), managed primarily by urology (79%), and the primary treatment was radical prostatectomy (71%). The total Cronbach's alpha coefficient was 0.84 demonstrating an acceptable internal consistency. The total ICC was also acceptable at 0.64. Conclusion: The Arabic version of the EPIC-CP is a reliable and valid tool for assessing health-related quality of life for Arabic patients with PCa.

Effective ureteral access sheath insertion during flexible ureteroscopy: Influence of the ureteral orifice configuration.

INTRODUCTION: We sought to determine the possible predictors for effective insertion of the ureteral access sheath (UAS) during flexible ureteroscopy (fURS) in virgin ureters and their impact on postoperative ureteral wall injury and the procedural outcome. METHODS: A retrospective review of prospectively collected data was performed for all consecutive patients scheduled for fURS of virgin ureters at two tertiary care centers between 2018 and 2020. Demographics, stone characteristics, and perioperative data, including the configuration of the ureteral orifice (UO) over introductory guidewire insertion, were collected. Multivariate logistic regression was used to detect possible predictors of successful UAS insertion. RESULTS: In total, 128 patients who underwent primary fURS were included, with a mean age of 43.3±12.3 years and a stone burden of 12.3±6.9 mm. One hundred and ten patients (85.9%) achieved successful ureteral access insertion, including 81 (63.3%) without ureteral dilatation and 35 with dilation, of which 29 (22.7%) had a successful UAS afterward, while six failed. Total patients who underwent ureteral orifice dilatation were 35. 29 had a successful UAS afterward, while 6 failed. Patients who underwent successful UAS placement into virgin ureters were significantly older and had a lower body mass index (BMI). A tent-shaped UO over the guidewire led to successful UAS insertion. In multivariate regression analysis, cases with BMI <30 kg/m2 (odds ratio [OR] 1.89, 95% confidence interval [CI] 1.28-7.03) and those with a tent-shaped UO over the introductory guidewire (OR 6.60, 95% CI 3.8-7.2) maintained their significance to predict successful UAS insertion into virgin ureters. Nine patients (8.2%) had ureteral mucosal injuries, and the overall stone-free rate was 78.2%. CONCLUSIONS: Patients with normal BMIs and tent-shaped UOs over the introductory guidewires are more likely to achieve primary UAS insertion without the need for ureteral dilation.

High-Grade Non-Muscle Invasive Bladder Cancer: When to Move to Early Radical Cystectomy?

Objectives To compare the outcomes of bladder preservation therapy with early or deferred radical cystectomy (RC) in high-grade non-muscle invasive bladder cancer. Methods Prospectively collected data were obtained for patients undergoing transurethral resection of bladder tumor (TURBT) at a tertiary care center between 2007 and 2018. Patients with a high-grade tumor (HGT1) were divided into three groups, depending on the treatment plan: conservative (GI), early RC (GII), or deferred RC (GIII). Kaplan-Meier analysis was performed to assess the cancer-specific survival (CSS). Results Seventy-one patients were included, and the patients had a median (range) age of 49 (32-72) years. The GI, GII, and GIII groups included 34 (47.9%), 14 (19.7%), and 23 (32.4%) patients, respectively. A significantly lower number of GII patients underwent >2 TURBTs (14.3% vs. 100%, p<0.001). Compared to GIII patients, GII patients had a shorter time to RC from the initial diagnosis (5.7 vs. 36.2 months, p=0.03). Ileal conduit and orthotropic bladder diversions were comparable between both groups, with significantly higher postoperative complications in GIII patients. The median (IQR) follow-up times for the groups were 84 (49-102), 82 (52-112), and 73 (36-89) months, respectively. The five-year and 10-year CSS for GII and GIII patients was 79% vs. 75% and 78% vs. 64%, respectively (log rank=0.19). Conclusion Early RC should be considered an alternative treatment option in selected patients with HGT1 BC with expected longer life expectancy, which may significantly decrease postoperative complications and improve the CSS. However, selection bias in the current retrospective study may influence these outcomes.

Robot-Assisted Radical Prostatectomy in Low-Volume Regions: Should It Be Abandoned or Adopted? A Multi-Institutional Outcome Study.

Purpose: To present multinational experience in robot-assisted radical prostatectomy (RARP) by fellowship-trained expertise in low-volume regions in Gulf Cooperation Council (GCC) countries and to compare the current results with global outcomes reported in recent meta-analyses. Methods: A retrospective review of prospectively collected data was performed for patients undergoing RARP for localized prostate cancer (PCa). Three fellowship-trained surgeons at four academic and referral centers in Saudi Arabia and Kuwait performed all procedures between February 2014 and December 2019. Data on demographics, perioperative characteristics, pathology, and adverse events were collected. Results: A total of 207 patients were included with a median (IQR) follow-up duration of 28 (15-38) months. The median prostate volume and prostate-specific antigen were 42 (32-53) g and 9.1 (5.8-14.1) ng/mL, respectively. While 65.2% of patients had a Gleason score ≥7, 20% had grade group 4 disease, and 7.8% had ≥cT3 disease. The mean ± SD operative time was 203 ± 52 minutes, and the mean estimated blood loss was 158 ± 107 mL. Only 4 (1.9%) patients received perioperative blood transfusions. Positive surgical margins were observed in 21.7% of patients, all of whom had ≥pT3 disease. There were 23 complications in 18 (8.7%) patients, including Clavien-Dindo grade III complications in 2.4%. At the 12-month follow-up, 35.8% of patients were potent, 94.6% were continent, and 9.2% had biochemical recurrence. Conclusions: The safety and efficacy of RARP by fellowship-trained expertise in GCC countries were well established. The outcomes seem promising and comparable to international centers and should improve with increasing case volume and fellowship-trained expertise.
