RESUMO
Hem-o-Lok clips (HOLCs) are a useful tool in mini-invasive surgery, especially for renal surgery. However, in rare cases, they could migrate into the collecting system and be calculogenic. We present a case of a 53 years old man with an incidental CT finding of a left staghorn caliceal stone increasing its size in the last 2 years. He had a medical history of ipsilateral robotic partial nephrectomy (RAPN) at another institution 8 years before and a previous renal colic with spontaneous stone elimination about 20 years before. The stone was located in the upper calyx. He underwent a flexible ureteroscopy. After an initial fragmentation, a Hem-o-lok was reported, partially wedged into the renal parenchyma. After removing the HOLC with a basket, a small urinary leak was observed and managed with a JJ stent placement. In the postoperative period, the patient had a fever managed with antibiotics and was discharged on the 4th postoperative day without problems. HOLC migration into the collecting system is a rare complication following robotic and laparoscopic renal surgery. HOLC could act as a nidus for stone formation. Avoiding too much tension during renal sutures using HOLC could reduce the possibility of migration. Simple knotting in particular conditions is a valuable option. However, this kind of stone can be managed endoscopically without complaints, minding the possibility that HOLC could be partially wedged into renal parenchyma leading to a urinary leak. With the widening indications for RAPN this kind of complication could be more frequent.
RESUMO
Background and Objectives: To assess the potential prognostic role of the systemic immune-inflammation index (SII) in predicting oncological outcomes in a cohort of patients treated with radical cystectomy (RC). Materials and Methods: From 2016 to 2022, a retrospective monocentric study enrolled 193 patients who were divided into two groups based on their SII levels using the optimal cutoff determined by the Youden index. The SII was obtained from a preoperative blood test approximately one month before RC. Univariable and multivariable logistic regression analyses were conducted to investigate the capacity of SII to predict lymph node invasion (N), advanced pT stage (pT3/pT4), and locally advanced condition at the time of RC. Multivariable Cox regression models adjusted for preoperative and postoperative features were used to analyze the prognostic effect of SII on recurrence-free survival (RFS), cancer-specific survival (CSS), and overall survival (OS). Results: The optimal cutoff value of the SII was 640.27. An elevated SII was seen in 113 (58.5%) patients. Using the multivariable preoperative logistic regression models, an elevated SII was correlated with nodal invasion (N; p = 0.03), advanced pT stage (p = 0.04), and locally advanced disease (p = 0.005), with enhancement of AUCs for predicting locally advanced disease (p = 0.04). In multivariable Cox regression models that considered preoperative clinicopathologic factors, an elevated SII was linked to poorer RFS (p = 0.005) and OS (p = 0.01). Moreover, on multivariable Cox regression postoperative models, a high SII was linked to RFS (p = 0.004) and to OS (p = 0.01). Conclusions: In this monocentric retrospective study, higher preoperative SII values predicted worse oncological outcomes in patients with bladder cancer (BCa) who underwent RC.

OBJECTIVE: To compare the efficacy of artificial urinary sphincter (AUS) vs retrourethral transobturator sling (RTS) in men with moderate post-prostatectomy urinary incontinence (PPI) using propensity score-matching analysis to enhance the validity of the comparison (Canadian Task Force classification II-2). PATIENTS AND METHODS: Consecutive men with moderate (3-5 pads/day) stress-prevalent PPI were included if implanted with a RTS (TiLOOP® Male; pfm medical, Köln, Germany) or AUS (AMS800® ; Boston Scientific, Boston, MA, USA) since July 2011 to December 2017 and with ≥12 months of follow-up. Preoperative assessment included 24-h pad usage, International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), urethrocystoscopy, and urodynamics if indicated. Propensity score-matching analysis was based on age, body mass index, Charlson Comorbidity Index, pad usage, previous radiotherapy, and urethrotomy. The primary outcome was at least 'much improved' response at 12-months according to the Patient Global Impression of Improvement questionnaire, without additional PPI surgery or prosthesis explantation. RESULTS: Of 109 included patients, 70 patients were matched and the study groups were well balanced for the baseline matched variables. The median baseline 24-h pad usage was four in both groups (P = 0.10), and median follow-up was 51.2 months for AUS and 47.2 months (P = 0.5) for RTS patients. In the AUS and RTS cohorts, respectively, 33 (94.3%) and 24 (68.6%) patients achieved the primary outcome (P < 0.001), the 0-1 pad/day rates was 94.3% vs 68.6% (P = 0.012) at 12 months, and 91.4% vs 68.6% (P = 0.034) at last follow-up. At the last follow-up, the median 24-h leakage volumes, median ICIQ-SF scores and satisfaction rates were 0 vs 15 mL (P = 0.017), 4 vs 10 (P = 0.001), and 94.3% vs 68.6% (P = 0.012) in the AUS and RTS cohorts, respectively. There were no significant differences in overall rates of complications and re-interventions, although Clavien-Dindo Grade III complications (n = 3) occurred only in the AUS group. At sensitivity analysis, the study was reasonably robust to hidden bias. CONCLUSION: We found that AUS implantation significantly outperformed RTS in patients with moderate PPI for both subjective and objective outcomes.

PURPOSE: The term aspirin-exacerbated respiratory disease (AERD) refers to a combination of asthma, chronic rhinosinusitis with nasal polyposis (CRSwNP), and acute respiratory tract reactions to nonsteroidal anti-inflammatory drugs. AERD has now been included among the CRSwNP endotypes, and is considered one of the most aggressive in terms of disease recurrence. Cortactin is a multi-domain protein with a part in several cellular mechanisms involving actin assembly and cytoskeleton arrangement. Cortactin seems to have a role in inflammatory responses and to be implicated in human airway secretion and contraction mechanisms. The novel aim of the present study was to examine cortactin expression in nasal polyps of a consecutive cohort of AERD patients and in nasal mucosa of a control group of patients. MATERIALS AND METHODS: Cortactin expression was assessed immunohistochemically in nasal polyps from 18 consecutive AERD patients who underwent endoscopic sinus surgery and in nasal mucosa of 19 patients without chronic rhinosinusitis. RESULTS: Concomitant allergy was found in 11 AERD patients, most of them male (8 cases; pâ¯=â¯0.02). Cortactin expression in nasal polyps was definitely high (+3) in 17 out of 18 cases, in both epithelial cells (cytoplasmic and membranous immunoreactivity) and activated fibroblasts. A higher cortactin expression was seen in female than in male AERD patients (pâ¯=â¯0.05). CONCLUSIONS: Given this preliminary evidence of cortactin upregulation in the polyps of AERD patients, prospective studies could further investigate the role of cortactin in the biology of AERD, and the potential role of cortactin-targeted approaches in integrated AERD treatments.

PURPOSE: Most primary tumors spreading metastasis to the parotid gland are usually located in the head and neck region, nonetheless, rarely, parotid gland can also be the target of metastatic localization site of distant primary tumors. The purpose of this study was to describe a clinical series of metastasis to the parotid gland from distant primary tumors (non Head & Neck). METHODS: The clinical databases of parotid tumors in two academic centers have been analyzed and 11 cases of parotid metastatic cancers from distant primary tumors were found. RESULTS: Primary tumor was lung cancer in 8 cases, and breast cancer, gastric carcinoma and pancreatic carcinoma in one case each. CONCLUSIONS: Parotid metastases can be the first clinical manifestation of a malignant tumor from a distant site and can manifest years after curative-intent treatment of the distant primary. Histopathology and immunohistochemistry can help in the identification of the primary site. Parotidectomy with complete excision of the parotid lesion may have diagnostic and/or loco-regional control and/or curative intent, however there is still no international consensus about the therapy of parotid malignant metastasis.

BACKGROUND: AL amyloidosis is a rare plasma cell dyscrasia with multiorgan involvement. Good risk patients are candidate to high dose chemotherapy and autologous stem cell transplantation. However both transplantation and stem cell collection entail significant risk in such patients. Plerixafor is a novel mobilizing agent approved for use in "poor mobilizer" patients with lymphoma and multiple myeloma; experience in systemic amyloidosis patients is limited. CASE REPORT: We describe a case of spontaneous splenic rupture following administration of G-CSF and plerixafor in a patient with AL amyloidosis who previously underwent heart transplantation due to amyloid heart involvement. RESULTS AND CONCLUSION: This is the first report of spontaneous splenic rupture following stem cell mobilization with G-CSF and plerixafor in AL amyloidosis. The role of plerixafor has to be established. AL amyloidosis patients undergoing stem cell mobilization need careful monitoring of signs and symptoms of spontaneous splenic rupture.

Temporal bone squamous cell carcinoma (TBSCC) is an uncommon, aggressive malignancy with a poor prognosis in advanced cases. The dismal outcome is partially related to: the lack of reliable clinical or pathological prognostic factors and the largely unstandardized surgical and integrated treatments adopted. There is an undeniable need for novel diagnostic/therapeutic strategies to improve the prognosis. The purpose of this critical review was to explore the level of available knowledge concerning the molecular markers involved in the biology of TBSCC that have a prognostic potential. The Pub-Med and Scopus electronic databases were searched without publication date limits for studies investigating molecular markers in cohorts of patients with primary TBSCC. The search terms used were: "temporal bone cancer", "temporal bone carcinoma", "temporal bone malignancy", "ear cancer", "ear carcinoma", and "ear malignancy". We decided preliminarily not to consider series with less than five cases. Nine retrospective case series of TBSCC were found in which different analytical techniques had been used to study the role of several biomarkers (HPV, vimentin, transforming growth factor ß, CD105, RECK, matrix metalloproteinase-9, MASPIN, EBV, p16, TP53 mutation, pSTAT3, relaxin-2). CD105 expression (in tumor vessel endothelial cells) and MASPIN cytoplasmic expression (in carcinoma cells) were, respectively, found directly and inversely related with the neoplasm's recurrence rate. CD105 expression was also inversely related with disease-free survival in TBSCC. A future goal of such analyses should be to ascertain the radio- and chemo-sensitivity profiles of individual TBSCCs, enabling truly personalized therapies. A further, more ambitious goal will be to find targets for therapeutic agents that might prove crucial in improving the disease-specific survival for patients with advanced TBSCC.

Even after appropriate surgical therapy, a significant number of patients with chronic rhinosinusitis with nasal polyps (CRSwNP) experience recurrences. The end-point of this prospective study was to apply univariate and multivariate statistical models to identify clinical, pathological, and laboratory variables that could predict CRSwNP recurrence after endoscopic sinus surgery. The study enrolled 143 patients between 2010 and 2013, who were all treated by the same surgeon for CRSwNP. Twenty-one patients developed recurrent polyposis. The recurrence rate was significantly higher for the eosinophilic than for the non-eosinophilic type (p = 0.020). Among the patients who developed a recurrence, the disease-free interval was significantly shorter for those with eosinophilic-type polyposis (p = 0.003). Univariate statistical analysis disclosed significant associations between CRSwNP recurrence and age (p = 0.035), allergy (p = 0.014), and eosinophilic granulomatosis with polyangiitis (p = 0.01). The multivariate model showed that only histological evidence of the eosinophilic type of CRSwNP retained an independent prognostic significance in relation to recurrent polyposis (p = 0.033). Judging from our results, it is reasonable to consider both stricter follow-up protocols and postoperative adjuvant medical treatments for patients with a histological diagnosis of eosinophilic-type CRSwNP.

PURPOSE: Despite improved surgical and medical therapies, recurrence remains a significant problem in chronic rhinosinusitis with nasal polyps (CRSwNP), given a recently-reported long-term revision rate of 15%-20%. In this prospective study uni- and multivariate statistical analyses were used to identify clinical, laboratory and conventional pathological parameters for pinpointing CRSwNP patients at higher risk of recurrence after functional endoscopic sinus surgery (FESS). MATERIALS AND METHODS: The investigation concerned 179 consecutive patients undergoing FESS for CRSwNP, and 24 of them developed recurrent CRSwNP after FESS. RESULTS: A univariate statistical model disclosed significant associations between recurrent CRSwNP and serum basophil counts (p=0.03) and percentages (p=0.02). The recurrence rate was higher for patients with eosinophilic-type CRSwNP (p=0.01). In a multivariate logistic model, eosinophilic-type CRSwNP (p=0.025) and serum basophil percentage (statistical trend, p=0.079) retained their independent prognostic significance in relation to CRSwNP recurrence. The discriminatory power of a three-variable panel (age <65 years, serum basophil percentage and eosinophilic type) featured an AUC (ROC) of 0.7028 (an acceptable discriminatory power according to the Hosmer-Lemeshow scale). CONCLUSIONS: Although our panel achieved an acceptable discriminatory power for CRSwNP recurrence, other parameters (including biomarkers) capable of predicting outcome and orienting postoperative treatment decisions need to be investigated in CRSwNP.

BACKGROUND: Adenosquamous carcinoma (ASC) of the head and neck is a rare malignancy characterized by loco-regional and distant aggressiveness. At histology, ASC reveals two distinct, juxtaposed components, squamous cell carcinoma (SCC), and true adenocarcinoma. METHODS: The immunohistochemical expression of AE3, CK19 and CAM5.2, and HPV infection was tested in a case of laryngeal ASC. RESULTS: The patient had no regional lymph node metastases, but developed a recurrence in neck soft tissues shortly after primary radical surgery. The laryngeal surgical specimen had the typical morphological features of ASC. The tumor's squamous and glandular components were both strongly and diffusely immunoreactive for AE3 and CK19, whereas CAM5.2 selectively stained only the gland-like part. We found no high- or low-risk HPV DNA (28 genotypes) in the specimens. The patient underwent salvage extended radical neck dissection and received postoperative radio-chemotherapy. At 4-month follow-up control, neck recurrence was found. Palliative chemotherapy was instituted. CONCLUSIONS: An accurate histological and immunohistochemical diagnosis is mandatory to differentiate ASC from conventional SCC. Radical surgical excision is recommended for laryngeal ASC. Adjuvant postoperative therapy is administered in most cases, but there are no widely accepted indications for these treatments.

Despite appropriate surgical therapy, 5-10 % of patients with chronic rhinosinusitis (CRS) and nasal polyps (NP) experience disease recurrences. It has been suggested that angiogenesis may relate to the pathogenesis and prognosis of CRS with NP. Endoglin (CD105) is a component of the receptor complex of transforming growth factor-beta, a pleiotropic cytokine that modulates angiogenesis. A series of patients treated surgically for CRS with NP was analyzed to assess the relationship between CD105 expression, main clinicopathological features, and recurrence rate. The immunohistochemical expression of CD105 was assessed in 70 patients consecutively operated for CRS with NP. In the univariate setting, the presence of CD105 (1/0) showed a trend towards a significant association with increasing NP dimensions (p = 0.054). Intensity of CD105 reaction was also significantly associated with NP size (0.04) and with an eosinophilic histology (p = 0.048). In our multivariate setting, only asthma (p = 0.016), hypereosinophilia (p = 0.022), and preoperative polyposis score (p = 0.046) retained their independent prognostic significance in relation to NP recurrence. Further efforts are needed to elucidate the biological, angiogenic and proliferative mechanisms behind recurrent NP. Our preliminary results support the clinical utility of extra postoperative care, in terms of closer follow-ups and medication with oral anti-histamines, topical and/or oral steroids, and antileukotrienes in patients with asthma, advanced nasal polyposis at presentation, and serum hypereosinophilia.

We examined the prevalence and prognostic relevance of bone marrow reticulin fibrosis in 526 patients with World Health Organization-defined polycythemia vera evaluated at the time of initial diagnosis. Seventy-four patients (14%) displayed mostly grade 1 reticulin fibrosis, with only 2 cases showing higher-grade fibrosis. Presenting clinical and laboratory characteristics, including JAK2V617F allele burden, between patients with and without fibrosis were similar for the most part, with the exception of a higher prevalence of palpable splenomegaly in patients with fibrosis (P < .01). Patients with fibrosis were less prone to experience thrombosis during their clinical course (1.1 vs 2.7 per 100 patient-years; P = .03) and more prone to develop post-polycythemia vera myelofibrosis (2.2 vs 0.8 per 100 patient-years; P = .01). There was no significant difference between the 2 groups in terms of overall or leukemia-free survival. The present study clarifies the incidence, degree, and prognostic relevance of bone marrow fibrosis obtained at time of initial diagnosis of polycythemia vera.

Diagnosis of essential thrombocythemia (ET) has been updated in the last World Health Organization (WHO) classification. We developed a prognostic model to predict survival at diagnosis, named IPSET (International Prognostic Score for ET), studying patients with WHO-defined ET. Age 60 years or older, leukocyte count ≥ 11 × 10(9)/L, and prior thrombosis significantly affected survival, by multivariable Cox regression. On the basis of the hazard ratio, we assigned 2 points to age and 1 each to leukocyte count and thrombosis. So, the IPSET model allocated 867 patients into 3 risk categories with significantly different survival: low (sum of points = 0; median survival not reached), intermediate (sum = 1-2; median survival 24.5 years), and high (sum = 3-4, median survival 13.8 years). The IPSET model was further validated in 2 independent cohorts including 132 WHO-defined ET and 234 Polycythemia Vera Study Group-defined ET patients. The IPSET model was able to predict the occurrence of thrombosis, and not to predict post-ET myelofibrosis. In conclusion, IPSET, based on age ≥ 60 years, leukocyte count ≥ 11 × 10(9)/L, and history of thrombosis allows prognostic assessment of WHO-defined ET and the validation process makes IPSET applicable in all patients phenotypically appearing as ET.

Deep neck infections (DNI) spread along fascial planes and involve neck spaces. Very few studies have investigated potentially prognostic factors using multivariate statistical models. Our aim was to analyze 282 consecutive cases of DNI using multivariate (logistic) statistical models to identify independent significant factors influencing prognosis in terms of complications and long-term hospitalization (>6 days). In our series, only involvement of more than one neck space was independently significant in prognosticating complications of DNI (odds ratio [OR] 2.46). The presence of comorbidities (OR 2.13), non-odontogenic sites of origin (OR 1.88), leukocyte counts above 11.0 cells × 10(9)/L at presentation (OR 3.57), and the need for both medical and surgical treatments (OR 4.66) was significantly and independently prognostic of long hospital stays. Multivariate analysis can distinguish between risk factors and their relative contribution to outcome. The few published studies using multivariate models to analyze DNI prognosis considered quite large cohorts, but no clinical variables persistently revealed an independent significant prognostic role. This evidence seems to underscore the complex interdependence of several clinical variables in contributing to DNI prognosis, and the heterogeneity of the diagnostic/therapeutic approaches adopted.

BACKGROUND: Periprocedural prophylaxis in medicine encompasses the set of measures (physical, chemical, and pharmacological) used to reduce the risk of infection. Antibiotic prophylaxis (AP) refers to the administration of a short-term regimen of antibiotics shortly before a medical procedure to reduce the risk of infectious complications that can result from diagnostic and therapeutic interventions. The outspreading growth of multidrug-resistant bacterial species and changes in the bacterial local ecosystem have impeded the development of a unique scheme of AP in urology. OBJECTIVES: To review the literature and current guidelines regarding AP for urological diagnostic and therapeutic procedures, and to define agents, timing, and occasions when administering pharmacological prophylaxis. Secondly, according to current literature, to open new scenarios where AP can be useful or useless. RESULTS: Major gaps in evidence still exist in this field. AP appears useful in many invasive procedures and some sub-populations at risk of infectious complications. AP is not routinely recommended for urodynamic exams, diagnostic cystoscopy, and extracorporeal shock-wave lithotripsy. The available data regarding the use of AP during the transperineal prostate biopsy are still unclear; conversely, in the case of the transrectal approach AP is mandatory. AP is still considered the gold standard for the prevention of postoperative infective complications in the case of ureteroscopy, percutaneous nephrolithotomy, endoscopic resection of bladder tumor, endoscopic resection of the prostate, and prosthetic or major surgery. CONCLUSION: The review highlights the complexity of determining the appropriate candidates for AP, emphasizing the importance of considering patient-specific factors such as comorbidities, immunocompetence, and the nature of the urologic intervention. The evidence suggests that a one-size-fits-all approach may not be suitable, and a tailored strategy based on the specific procedure and patient characteristics is essential.

BACKGROUND: Urolithiasis prevalence varies globally between 1-20%, influenced by regional factors. Robotic pyelolithotomy (RPL) presents an interesting alternative to PCNL, considered the gold standard for symptomatic stones smaller than 20 mm, as it carries a risk of significant complications. However, studies on RPL are limited, especially in anatomically complex cases, where RPL proves to be particularly useful. The study aims to update and review outcomes of RPL in a high-volume robotic center. METHODS: A retrospective analysis of 153 patients treated with RPL for staghorn kidney stones at a single center from February 2016 to December 2023 was conducted. Data including demographics, preoperative renal function, stone characteristics, operative and postoperative outcomes, and costs were collected. Stone-free rates (SFR) and complications were assessed at follow-up intervals up to 12 months post-surgery. RESULTS: The study showed an initial 3-month stone-free rate (SFR) of 93.5%, which decreased to 83.5% at 12-months. This trend may reflect new stone formation rather than procedure failure. Sub-analysis revealed a significant difference in SFR between patients with pelvic and pyelocalyceal stones at each follow-up. Multivariate regression analysis identified in the pyelocalyceal group that higher BMI and larger stones were associated with higher failure rates at both 6 and 12 months. CONCLUSIONS: RPL is a safe and effective treatment for large renal stones, offering a high SFR and low complication rate. It is particularly beneficial in cases with complex anatomy or requiring concurrent renal procedures. However, patient selection is crucial, considering factors like stone location and size. Further research is needed to compare RPL with other treatment methods.
RESUMO
INTRODUCTION: Botulinum toxin A (BoNT-A) injections in the prostate gland have been used as a minimally invasive option for treating bladder outlet obstruction (BOO). However, the efficacy of transurethral BoNT-A injections for BOO is not well established in the literature. The aim of this study is to collect evidence on the efficacy of transurethral BoNT-A injections for the treatment of BOO. MATERIALS AND METHODS: This systematic review and meta-analyses was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. A systematic literature search was performed till December 2022. The study population consisted of adult patients diagnosed with BOO, who underwent transurethral injections of BoNT-A for the treatment of BOO. EVIDENCE SYNTHESIS: Out of 883 records, we identified seven studies enrolling 232 participants, of which only one nonrandomized controlled trial was found. Four prospective studies and two retrospective studies. Three studies included patients with lower urinary tract symptoms (LUTS) and benign prostatic hyperplasia (BPH) and were included in the meta-analysis. Three studies included patients with urethral sphincter hyperactivity. One study included patients with primary bladder neck disease (PBND). All studies showed significant improvements from baseline in maximum urinary flow rate (Qmax), International Prostate Symptom Score (IPSS), and postvoid residual (PVR) at 3 and 6 months. The adverse events were mild in all studies. Hematuria, UTI, and urinary retention were reported across all studies. CONCLUSION: In conclusion, transurethral BoNT-A injections have been shown to improve LUTS, QoL, and urodynamic parameters of individuals with BOO at 3 and 6 months after injections, and no serious adverse effects have been reported. However, data on the long-term benefits of this treatment are scarce, and more prospective, randomized studies with larger samples examining various injection techniques, dosages, and extended follow-up of recurrent injections are needed.

Inflammation is widely acknowledged as a significant characteristic of cancer, playing a substantial function in both the initiation and advancement of cancers. In this research, we planned to compare pan-immune inflammation markers and other well-known markers (systemic immune inflammation index and neutrophil to lymphocyte ratio) to predict prognosis in individuals treated with radical cystectomy for bladder cancer. METHODS: In this retrospective analysis, we focused on preoperative PIV, systemic immune inflammation index (SII), and neutrophil-lymphocyte ratio (NLR) in 193 individuals managed with radical cystectomy for bladder cancer between January 2016 and November 2022. Multivariable logistic regression assessments were performed to assess the predictive capabilities of PIV, SII, and NLR for infiltration of lymph nodes (N), aggressive tumor stage (pT3/pT4), and any non-organ limited disease at the time of RC. Multivariable Cox regression analyses were conducted to assess the predictive impact of PIV on Relapse-free survival (RFS), Cancer-specific survival (CSS), and Overall survival (OS). RESULTS: Our individuals were divided into high PIV and low PIV cohorts using the optimal cut-off value (340.96 × 109/L) based on receiver operating characteristic curve analysis for relapse-free survival. In multivariable preoperative logistic regression models, only SII and PIV correlated with the infiltration of lymph nodes, aggressive disease, and any non-organ confined disease. In multivariable Cox regression models considering presurgical clinicopathological variables, a higher PIV was associated with diminished RFS (p = 0.017) and OS (p = 0.029). In addition, in multivariable Cox regression models for postoperative outcomes, a high PIV correlated with both RFS (p = 0.034) and OS (p = 0.048). CONCLUSIONS: Our study suggests that PIV and SII are two very similar markers that may serve as independent and significant predictors of aggressive disease and worse survival impacts on individuals undergoing radical cystectomy for bladder neoplasm.
RESUMO
BACKGROUND: Robotic-assisted surgery is the gold standard for performing radical prostatectomy (RARP), with new robotic devices such as HugoTM RAS gaining prominence worldwide. OBJECTIVE: We report the surgical, perioperative, and early postoperative outcomes of RARP using HugoTM RAS. DESIGN, SETTING, AND PARTICIPANTS: Between April 2022 and October 2023, we performed 132 procedures using the Montsouris technique with a four-robotic-arm configuration in patients with biopsy-proven prostate cancer (PCa). OUTCOME MEASURES: We collected intraoperative and perioperative data during hospitalization, along with follow-up data at predefined postoperative intervals of 3 and 6 months. RESULTS AND LIMITATIONS: Lymphadenectomy was performed in 25 procedures, with a bilateral nerve-sparing technique in 33 and a monolateral nerve-sparing technique in 33 cases. The mean total surgery time was 242 (±57) min, the mean console time was 124 (±48) min, and the mean docking time was 10 (±2) min. We identified 17 system errors related to robotic arm failures, 9 robotic instrument breakdowns, and 8 significant conflicts between robotic arms. One post-operative complication was classified as Clavien-Dindo 3b. None of the adverse events, whether singular or combined, increased the operative time. Positive margins (pR1) were found in 54 (40.9%) histological specimens, 37 (28.0%) of which were clinically significant. At 3 and 6 months post-surgery, the PSA levels were undetectable in 94.6% and 92.1% of patients, respectively. Social urinary continence was regained in 86% after 6 months. Limitations of our study include its observational monocentric case-series design and the short follow-up data for functional and oncological outcomes. CONCLUSIONS: Our initial experience highlights the reliability of the HugoTM RAS system in performing RARP. Additionally, we also list problems and solutions found in our daily work.
RESUMO
Background: Gross Hematuria is a relevant cause of admission to the emergency department in the general population and particularly in older adults (≥80 years). This specific urological symptom is often underestimated and usually associated with benign conditions such as urinary infections or poor hydration. Nevertheless, hematuria could lead to severe acute complications or be the first symptom of urological cancers. Methods: We retrospectively analyzed clinical data from 1169 patients aged ≥80 years consecutively admitted to the emergency department for hematuria. The primary endpoint of the study was to identify risk factors for major complications, and the secondary endpoint was to analyze risk factors for urological cancer diagnosis. The median age was 85 years (IQR 82-88 years), and 908 (77%) were males. Among them, 449 (38.4%) had a past medical history of urological neoplasm (kidney, ureter, bladder, prostate, or urethral cancer). Results: Overall, 87 patients (7.4%) had major complications (patient death, septic shock, and admission to the intensive care unit). Worse vital signs at admission, fever, and confusion (p < 0.001, OR 18.0 IC 95% [5.5-58.7]; p = 0.015, OR 2.0 IC 95% [1.1-3.5]; p = <0.001, OR 4.2 IC 95% [1.9-3.5], respectively), as well as lower hemoglobin values and higher Charlson comorbidity index (p < 0.001, OR 0.8 IC 95% [0.7-0.9]), p = 0.002, OR = 1.2 [1.1-1.3]) were independent predictive factors for major complications. The multivariate analysis identified as risk factors for diagnosis of urological cancer older age, male sex and higher comorbidity (OR 1.05 IC95% [1-1.09]; OR 2.19 IC95% [1.42-3.39] and OR 1.11 IC95% [1.2-1.2], respectively); interestingly the presence of indwelling vesical catheter (IVC) (OR 0.44 IC95% [0.24-0.82]) resulted as an independent factor for absence of urological cancers. Conclusions: Hematuria is a frequent symptom in older adults admitted to the emergency department. While this is often associated with benign conditions, there are some risk factors for major complications and for urological cancer that must be taken into account to identify the patients who need further evaluation or prompt hospital admission.
