Limited high-quality studies have compared robot-assisted laparoscopic prostatectomy (RALP) vs open retropubic radical prostatectomy. We sought to compare their postoperative outcomes in a randomized ...setting.
In a single center, 354 men with newly diagnosed prostate cancer were assessed for eligibility; 342 were randomized (1:1). The primary outcome was 90-day complication rates. Functional outcomes and quality of life were assessed over 18 months, and oncological outcomes, biochemical recurrence-free survival, and additional treatment over 36 months.
From 2014 to 18, 327 patients underwent surgery (retropubic radical prostatectomy = 156, RALP = 171). Complications occurred in 27 (17.3%) vs 19 (11.1%;
= .107). Patients undergoing RALP experienced lower median bleeding (250.0 vs 719.5 mL;
< .001) and shorter hospitalization time. Urinary EPIC (Expanded Prostate Cancer Index Composite) median scores were better for RALP over 18 months, with higher continence rate at 3 months (80.5% vs 64.7%;
= .002), 6 months (90.1% vs 81.6%;
= .036) and 18 months (95.4% vs 78.8%;
< .001). Sexual EPIC and Sexual Health Inventory for Men median scores were higher with RALP up to 12 months, while the potency rate was superior at 3 months (23.9% vs 5.3%;
= .001) and 6 months (30.6% vs 6.9%;
< .001). Quality of life over the 18 months and oncological outcomes over 36 months were not significantly different between arms.
Complications at 90 days were similar. RALP showed superior sexual outcomes at 1 year, improved urinary outcomes at 18 months, and comparable oncological outcomes at 36 months.
Both robotic surgery and head-down tilt increase intracranial pressure by impairing venous blood outflow. Prostatectomy is commonly performed in elderly patients, who are more likely to develop ...postoperative cognitive disorders. Therefore, increased intracranial pressure could play an essential role in cognitive decline after surgery. We describe a case of a 69-year-old male who underwent a robotic prostatectomy. Noninvasive Brain4careTM intraoperative monitoring showed normal intracranial compliance during anesthesia induction, but it rapidly decreased after head-down tilt despite normal vital signs, low lung pressure, and adequate anesthesia depth. We conclude that there is a need for intraoperative intracranial compliance monitoring since there are major changes in cerebral compliance during surgery, which could potentially allow early identification and treatment of impaired cerebral complacency.

Background: Partial nephrectomy (PN) is the standard of care in the management of cT1a tumors, while radical nephrectomy (RN) is indicated in more advanced tumors. Recent studies ...provided evidence that PN could be performed in patients with tumors greater that 7 cm with complication rates and oncological outcomes comparable with those undergoing RN. This study compares the recurrence-free survival (RFS), overall (OS) and cancer-specific survival (CSS) of PN and RN in patients with non-metastatic pathological T3a renal cell carcinoma (RCC) with perirenal fat invasion only. Methods: We reviewed 1202 patients undergoing RN (n = 653) and PN (n = 549), at a oncological referral center, from January 2003 to June 2016. Of all patients, we identified 25 RN and 41 PN pT3a tumors with exclusively perirenal fat invasion. None had nodal or distant metastasis at pretreatment clinical staging. Patients characteristics were compared with Mann-Whitney U test and Student t-test for categorical and numeric variables with normal distribution, respectively. Both groups were compared for RFS, OS and CSS with a Kaplan-Meier survival analysis. Results: All patients included had pT3a stage with isolated perirenal fat invasion. Groups undergoing RN and PN were not significantly different regarding Charlson Comorbidity Index (Median 3 for RN vs 4 for PN, p = 0.24) or Age (Mean 65.3 for RN vs 62.0 for PN, p = 0.99). Patients undergoing RN had bigger tumors (7.9 cm vs 4.6, p < 0.001) and higher Fuhrman grade (p = 0.01). Median follow-up was 36 months for RN and 34 months for PN. At the end of follow-up, recurrence was seen in 3 patients undergoing RN (12%) and 2 undergoing PN (5%), p = 0.36. Mortality was similar across groups (16% for RN vs 15% for PN, p = 0.99) as well as Cancer-specific mortality (4% for RN vs. 5% for PN, p = 0.99). At the end of follow-up, RFS was 80% (20/25) for RN and 82% (34/41) for PN. Conclusions: In our data, renal cell carcinoma with T3 stage due to perirenal fat invasion exclusively had similar outcomes when treated with Radical or Partial Nephrectomy. OS as well as RFS were comparable for both surgical modalities, suggesting that, although RN is currently the gold standard for this staging, PN may provide similar oncologic results.
The objective of this study is to report the first multicentric Brazilian series and learning curve of robotic radical cystectomy (RARC) with related intra- and postoperative outcomes. We ...retrospectively analyzed 37 RARC prospectively collected at four different centers in Brazil, from 2013 to 2019. We analyzed the patient’s demographics, pathological tumor, and nodal status, as well as intra- and postoperative outcomes. Statistical analysis was performed with the IBM (SPSS version 25) software. Overall, 86% were male, and the median age was 69 years. 83% had muscle-invasive bladder cancer, and 17% a high-grade, recurrent non-muscle-invasive tumor. The median operative time was 420 min with 300 min as console time. Median blood loss was 350 ml and transfusion rate was 10%. In 68% of the cases, we performed an intracorporeal Bricker urinary diversion, 24% intracorporeal neobladder, and 8% ureterostomy. Six patients (16%) had a Clavien 1–2, 8% had Clavien 3, 2.5% had a Clavien 4, and 5% had Clavien 5. The median length of hospital stay was 7 days. The final pathological exam pointed out pT0 in 16%, pT1 in 8%, pT2 in 32%, ≥ pT3 in 27%, and 16% pTis. 95% had negative surgical margins. The survival at 30, 90, and 180 days was 98%, 95%, and 95%, respectively. To our knowledge, this is the first multicentric series of RARC reporting the learning curve in Brazil; even if still representing a challenging procedure, RARC could be safely and effectively faced by experienced surgeons at centers with high volumes of robotic surgery.
To evaluate the relation between serum total testosterone (TT) and prostate cancer (PCa) grade and the effect of race and demographic characteristics on such association.
We analyzed 695 patients ...undergoing radical prostatectomy (RP), of whom 423 had serum TT collected. Patients were classified as having hypogonadism or eugonadism based on two thresholds of testosterone: threshold 1 (300 ng/dL) and threshold 2 (250 ng/dL). We evaluated the relation between TT levels and a Gleason score (GS) ≥ 7 in RP specimens. Outcomes were evaluated using univariate and multivariate analyses, accounting for race and other demographic predictors.
Out of 423 patients, 37.8% had hypogonadism based on the threshold 1 and 23.9% based on the threshold 2. Patients with hypogonadism, in both thresholds, had a higher chance of GS ≥ 7 (OR 1.79, p=0.02 and OR 2.08, p=0.012, respectively). In the multivariate analysis, adjusted for age, TT, body mass index (BMI) and race, low TT (p=0.023) and age (p=0.002) were found to be independent risk factors for GS ≥ 7. Among Black individuals, low serum TT was a stronger predictor of high-grade disease compared to White men (p=0.02).
Hypogonadism is independently associated to higher GS in localized PCa. The effect of this association is significantly more pronounced among Black men and could partly explain aggressive characteristics of PCa found in this race.
