Effect of Hypertension on Outcomes of High-Risk Patients After BCG-Treated Bladder Cancer
Immunotherapy with Bacillus Calmette Guerin (BCG) is the most efficacious treatment for high-risk bladder cancer (BC) (Ta/T1 or carcinoma in situ) to reduce the risk of recurrence. Our aim was to evaluate whether hypertension and diabetes influence the outcome of patients with noninvasive BC treated with BCG instillations.
In order to collect homogeneous data, we considered as "hypertensive" only those patients who had previous diagnosed hypertension and a history of taking medical therapy with antihypertensive drugs (AHT), and as "diabetic" only those prescribed oral antidiabetics or insulin (ADT).
We analyzed 343 high-risk BC patients undergoing BCG 1995 2010) with a median follow-up of 116 months (range 48-238). The distribution of various kinds of AHT and antidiabetic drugs was homogeneous, with no significant differences (p > 0.05).
In both univariate and multivariate analyses, the only statistically significant parameter propostic for recurrence after BCG treatment was AHT. Recurrence-liee survival curves showed a significant correlation with AHT (p = 0.0168, hazards ratio [HR] 1.45, 95% confidence interval [CI] 1.0692-1.9619); there was no correlation ( p = 0.9040) with ADT (HR 0.9750, 95% CI 0.6457-1.4721). After stratification of AHT and A.DT according to drug(s) prescribed, there were no significant differences in the BC recurrence rate (p > 0.05).
In this study with a very long-term follow-up, hypertension alone (evaluated by AHT) revealed the increased risk of BC recurrence after BCG treatment.
Several hypotheses have been formulated to support these findings, but further prospective studies are needed to both evaluate the real influence of hypertension and identify a possible prognostic factor to be used in selecting poor-prognosis BC patients as early candidates for surgical treatment
Anesthesiologic effects of transperitoneal versus extraperitoneal approach during robot-assisted radical prostatectomy: results of a prospective randomized study

Peripheral primitive neuroectodermal tumor of seminal vesicles: is there a role for relatively aggressive treatment modalities?
A 50 year old white man received an incidental ultrasound diagnosis of hypoechoic mass interesting the right seminal vesicle. A CT scan showed the presence of a 7.8 cm roundish cyst, originating from the right seminal vesicle. He had been followed by the removal of the right seminal vesicle and both the cystic lesion. The histological findings of the specimen documented the presence of small round cells compatible with Ewing's sarcoma/PPNET. The patient received also adjuvant chemotherapy and radiation treatment. After 10 years, the follow-up is still negative
Positive Surgical Margins After Partial Nephrectomy: A Systematic Review and Meta-Analysis of Comparative Studies
Objective: We performed an update of previous reviews of the literature to provide an overview on incidence, predictive factors, management and prognosis of positive surgical margins (PSMs) after partial nephrectomy (PN) including recent surgical series and studies comparing different approaches and techniques. Material and methods: A literature search was performed from January 2013 to January 2018 using the Medline database. The search strategy included a free-text protocol using the term "nephron-sparing surgery" OR "partial nephrectomy" AND "positive surgical margins" across the title and abstract fields of the records. From each selected study, we extracted the following data: number of analyzed patients, study design, approach and surgical technique used, PSMs rate, pathological features, type of PSMs treatment, mean (median) follow-up duration and final patient status. Meta-analysis was conducted using Review Manager software v. 5.2 (Cochrane Collaboration, Oxford, UK). Results: We selected a total of 36 (48%) studies. All studies were retrospective and the best statistical method used for comparison was the matched-pair analysis (level 4). Overall, 45,786 patients treated with PN were included in the selected studies. PSMs were reported in a total of 3,093 (6.7%) patients. The mean estimated PSMs rate was 7%, 5% and 4.3% in patients who underwent robot-assisted PN (RAPN), laparoscopic PN (LPN) and open PN (OPN), respectively. Comparative studies showed a significant advantage in favor of OPN compared with minimally invasive approach, while RAPN showed more favourable PSMs risk compared with LPN (odds ratio 3.02, 95% confidence intervals 2.05–4.45). No differences were detected stratifying data according to other surgical or tumor-related factors. Tumor size, nuclear grading and pT3a stage represent the most important predictors of PSMs. In 6,809 patients, follow-up data were available. Only 101 (1.4%) local recurrences and 88 (1.3%) distant recurrences were observed both in PSMs and negative surgical margins subgroups. PSMs were associated with a significant increased risk of local recurrence with a significant impact on local recurrence-free survival and metastasis-free survival. However, a significant impact on cancer-specific and overall survival could not be demonstrated. Conclusions: Studies published in the last 5 years confirmed that PSMs after PN are a rare condition. Although PSMs increase the risk of local and distant recurrence, their influence on cancer-specific and overall survival seems to be limited. Close surveillance should be strongly recommended as initial treatment of patients with PSMs after PN
Wunderlich's syndrome: Three cases of acute spontaneous renal bleeding, conservately treated
Wunderlich's syndrome is a clinical condition defined as a spontaneous renal bleeding of non traumatic origin, contained within the Gerota's fascia. Wunderlich's syndrome is rare. Spontaneous bleeding of kidney tumors, either benign or malignant, represents the more common causes. Classically it presents with acute flank pain, tender palpable mass and clinical hemodynamic deterioration. These symptoms are defined as the Lenk's classic triad. We present three cases of spontaneous renal bleeding
