Introduction: Similar to bladder cancer, about one third of upper tract urothelial carcinoma (UTUC) present variant histology (VH). We aim to evaluate the incidence, clinical characteristics and the impact on outcomes of VH in UTUC., Methods: We consecutively enrolled 77 patients treated between 2009 and 2022 by radical surgery for UTUC from a secondary and a tertiary referral center. A pathology review of all specimens was performed by 1 independent uropathologist for each center. We compared pure UTUC and UTUC with VH and the accuracy of endoscopic biopsy. Descriptive and comparative analysis was performed to assess the association with clinical characteristics and the Kaplan-Meier estimator to compare outcomes., Results: Median follow-up after surgery was 51 months. VH was present in 21/77 (28%) patients and 4/21 (19%) patients had multiple variants. The most frequent VH was squamous 12/21 (57%), followed by glandular 7/21 (33%) and micropapillary 3/21 variants (14%). Neuroendocrine carcinoma was present in 2 patients. Nested variant was found in 1 patient. Muscle invasive tumor (≥pT2) was present in 30/56 (54%) patients with pure UTUC and in 18/21 (86%) patients with VH (P < 0.05). Presence of carcinoma in situ was seen in 24/56 (43%) patients with pure UTUC and in 16/21 (76%) with VH (P < 0.05). Cumulative 8/56 (14%) with pure UTUC had a nonintravesical recurrence (6 patients with local and 2 distant recurrence) compared to 8/21 (38%) (3 local, 3 nodal, 2 distant) in the subgroup with VH (P < 0.05). Opposite effect was noted for bladder recurrence: 60% for pure UTUC vs. 29% for tumors with VH (P < 0.05). Review of preoperative endoscopic biopsy did not show the presence of VH in any patients. Differences in outcomes did not reach significance: 3yr-OS 63% vs. 42% (P 0.28) and 3yr-CSS 77% vs. 50% (P 0.7)., Conclusion: Almost a third of UTUC present VH. Presence of VH is related to more aggressive tumor characteristics and associated with unfavorable outcomes. Due to a higher rate of extravesical recurrences in UTUC with VH, Follow-up controls should include cross sectional imaging and cystoscopy., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

The majority of bladder cancers (BCs) are non-muscle invasive BCs (NMIBCs) and show the morphology of a conventional urothelial carcinoma (UC). Aberrant morphology is rare but can be observed. The classification and characterization of histologic subtypes (HS) in UC in BC have mainly been described in muscle invasive bladder cancer (MIBC). However, the currently used classification is applied for invasive urothelial neoplasm and therefore, also valid for a subset of NMIBC. The standard transurethral diagnostic work-up misses the presence of HS in NMIBC in a considerable percentage of patients and the real prevalence is not known. HS in NMIBC are associated with an aggressive phenotype. Consequently, clinical guidelines categorize HS of NMIBC as "(very) high-risk" tumors and recommend offering radical cystectomy to these patients. Alternative strategies for bladder preservation can only be offered to highly selected patients and ideally within clinical trials. Novel treatment strategies and biomarkers have been established MIBC and NMIBC but have not been comprehensively investigated in the context of HS in NMIBC. Further evaluation prior to implementation into clinical practice is needed., Competing Interests: Conflict-of-interest statement: The authors have no conflicts of interest to declare., (©The Author(s) 2024.

We performed a urine cytology analysis of a pharmacologically induced diuresis for the diagnosis of upper tract urothelial carcinoma. To evaluate the diagnostic value of cytology of pharmacologically forced diuresis, an initial cohort of 77 consecutive patients with primary upper tract urothelial carcinoma treated via radical surgery was enrolled. To evaluate pharmacologically forced diuresis cytology as a follow-up procedure, a second cohort of 1250 patients who underwent a radical cystectomy for bladder cancer was selected. In the first cohort, the sensitivity of cytology of pharmacologically forced diuresis in patients with invasive, high-grade, low-grade, and concomitant carcinoma in situ was 8%, 9%, 0%, and 14%, respectively. In the second cohort, cytology of pharmacologically forced diuresis was positive in 30/689 (4.3%) patients, in whom upper urinary tract recurrence was present in 21/30 (70%) of cases, and urethral recurrence was present in 8/30 (26%) of cases. As a follow-up tool, cytology of pharmacologically forced diuresis showed a sensitivity, specificity, and positive and negative predictive values of 60%, 99%, 70%, and 98%, respectively. Overall, as a diagnostic tool, the sensitivity of cytology of pharmacologically forced diuresis is slightly better in patients with invasive upper tract urothelial carcinoma and concomitant carcinoma in situ. As a follow-up method, positive cytology of pharmacologically forced diuresis is strongly related to cancer recurrence and can reveal urethral recurrence. Cytology of pharmacologically forced diuresis might be useful in cases with contraindications for imaging or when achieving endoscopic access to the upper urinary tract is difficult.

Prostatic Artery Embolization (PAE) - Endo-vascular Treatment of Lower Urinary Tract Symptoms Presumed Secondary to Benign Prostatic Obstruction Abstract: Based on the available evidence on efficacy and safety in the short to midterm, Prostatic Artery Embolization (PAE) is now endorsed by international evidence-based guidelines as a treatment of lower urinary tract symptoms presumed secondary to benign prostatic obstruction (LUTS/BPO) for selected patients. As PAE has a unique treatment approach (i.e., endovascular instead of transurethral), its profile and ideal application differ clearly from other treatments of LUTS/BPO, which must be considered for patient selection. Performance in local anesthesia with ongoing anticoagulation and no upper prostate size limitation represent advantages of the technique. Limited availability, an inferior relief of obstruction associated with higher retreatment rates and inferior outcomes in small prostates represent disadvantages. This should be considered for patient selection and counselling.

Urothelial carcinomas (UC) arise from the urothelium that covers the proximal urethra, urinary bladder, and the upper urinary tract. In daily routine and clinical trials UC originating from different locations are often treated and investigated in the same manner. However, differences between the two locations seem to be apparent and may question in handling them as a single oncologic entity. In this review we discuss similarities and differences between bladder and upper urinary tract UC and consider their potential impact on treatment strategies. Despite similarities of UC in the bladder (BC) and the upper urinary tract (UTUC), clinicopathologic and molecular differences may question to generally assemble both as a single tumor entity. Treatment standards for UTUC are often adopted from BC. However, a specific investigation in the former may still be meaningful as shown by the example of adjuvant cisplatin based chemotherapy. In conclusion, future investigations should prioritize the understanding of the tumor biology of both BC and UTUC. This may reveal which UTUC can be treated according to treatment standards of BC and in which cases, a separate approach may be more appropriate., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at http://dx.doi.org/10.21037/tau-20-1472).

Background: We compared a bundle of interventions including wound infiltration and continuous infusion with local anesthetics plus a single morphine bolus (CWI-M) with continuous epidural infusion (CEI) as postoperative analgesia., Methods: Fifty-one adults undergoing open abdominal aortic aneurysm repair were randomized in this non-inferiority open-label trial. In the CEI group, patients received thoracic epidural levobupivacaine 0.12% plus sufentanil 0.4 µg/mL infusion for 48 hours. In the CWI-M group, the wound was infiltrated with 10 mL levobupivacaine 0.5%, patients received a morphine bolus before the end of anesthesia and levobupivacaine 0.25% infusion through two multi-holed pre-peritoneal catheters for 48 hours. Systemic morphine was administered as rescue in both groups. The primary endpoint was the mean Numeric Rating Scale score in the first 48 hours after surgery., Results: Mean NRS was 1.7 (95% CI: from 1.2 to 2.2) in the CEI and 2.2 (95% CI: from 1.7 to 2.7) in the CWI-M group, the 90% CI of difference was from -0.1 to 1.1, not including the non-inferiority margin of 1.3. The cumulative rescue morphine dose per patient was higher in CWI-M than in CEI group (3.7±4.4 vs. 0.8±2.4 mg, P=0.006); moreover, NRS at arousal was higher in CWI-M (P=0.003). No differences were observed in postoperative hemodynamic parameters, recovery-related outcomes, length of stay nor complications., Conclusions: CWI-M was comparable to CEI in in postoperative pain control, but it was associated with higher need of rescue systemic opiates and with a worse early pain control.

Unlabelled: A nasal septal abscess is usually the result of an infected hematoma of the septum. A secondary septal abscess may be the result of infections extending from any of the neighbouring tissues. The necrosis of septal cartilage may lead to nasal deformities and severe impairment of nasal patency and growth., Objectives: Assess if the drainage of the abscess and the immediate reconstruction of the destroyed nasal septum in the acute phase is the best treatment to prevent short- and long-term effect on nasal and midface growth., Methods: Three pediatric patients treated with drainage and immediate implantation of homologous bank cartilage prior to 1990 and four treated with mosaic plastic using small pieces of residual septal cartilage assembled with fibrin glue., Result: No complication were observed in the follow-up and any deformities in the long-term controls., Conclusions: The drainage and immediate reconstruction of the nasal septum are the golden standard in the treatment of the septum infected haematoma.
