Based on the imago Dei theory, this essay attempts to establish a correspondence between the union of natures in Christ and the relationship between man and creation, focusing attention on the communication of idioms and reciprocal indwelling. It compares the dominion that man is called to exercise over nature by divine vocation as an image of the hypostatic union, with the despotic dominion, so widespread in modern times, that reflects the fall and is characterized by conflict and not by harmony. Finally, it is maintained that the form of dominion inspired by the application of the Christological doctrine inserts man in necessity and the cosmic rhythms, favoring the development of a human community aligned with the liturgical cycle and founded on peace.

Background/Objectives: Lower urinary tract symptoms (LUTSs) due to benign prostatic obstruction (BPO) represent a common condition affecting aging men. Transurethral resection of the prostate represents the gold standard surgical treatment but is not without complications such as retrograde ejaculation, bleeding and urinary retention. The temporary implantable nitinol device (iTIND) is considered a minimally invasive surgical technique, designed to treat LUTS while preserving erectile and ejaculatory function. Herein we report the results of a multi-center, real-world assessment of the iTIND procedure. Methods: Data from five international centers treating LUTS with the iTIND device were collected. We recorded changes through an International Prostatic Symptom Score (IPSS) questionnaire with Quality of Life (QoL), International Index of Erectile Function (IIEF5) questionnaire, antegrade ejaculatory function, maximum flow (QMax), post voiding residual volume (PVR) and freedom from repeat intervention. Results: A total of 74 subjects were enrolled; median follow-up was 12 months. IPSS and QoL changed from a median of 23 and 4 points at baseline to 11 and 2 points, respectively, at the last follow-up. A mean improvement in Qmax and PVR from 9 mL/s and 56 mL at baseline to 13 mL/s and 40 mL was noticed at the last follow-up. Total median operative time was 10 min, and the median time of iTIND indwell time was 7 days. The median device removal time was 5 min. There were no changes in IIEF5 scores and antegrade ejaculation rate. No intraoperative complications were reported, and non-serious postoperative complications occurred in six patients (two urinary retention, two mild haematuria, two urinary tract infection). Finally, four patients underwent reoperation during the follow-up period. All procedures were performed as outpatient day cases. Conclusions: Our results confirms that treatment with the iTIND is effective and safe in terms of improving urinary symptoms and quality of life without impacting sexual function. Longer follow-up is required to better define the durability of this minimally invasive procedure. Full article

Background: Pleural effusion is a common clinical condition encountered in emergency departments and often requires timely therapeutic intervention. This study aimed to assess the effectiveness and safety of ultrasound-guided pigtail catheter drainage in patients presenting with symptomatic pleural effusion. Methods: We conducted a retrospective analysis of 134 drainage procedures performed in a tertiary hospital emergency department in 2024. Adult patients who underwent ultrasound-guided drainage were included regardless of primary diagnosis. Results: Clinical improvement was observed in 86.6% of patients, while radiological improvement—assessed only in cases with complete follow-up imaging—was seen in 56.0%. Procedure-related complications were rare (3.7%), and 50% of patients were discharged directly from the emergency department, highlighting the feasibility of ambulatory management. Nearly half of the patients had underlying malignancy and were receiving palliative care. Conclusions: While indwelling pleural catheters (IPCs) are typically used in long-term outpatient settings, our study focused on temporary pigtail catheter drainage performed in-hospital as a symptom-relieving intervention. The findings align with previous studies supporting the safety and effectiveness of small-bore catheter use in this context. Ultrasound-guided pigtail drainage represents a low-risk, patient-centered approach that can reduce the burden on inpatient services and enhance quality of care for individuals with advanced disease. This method may be considered a first-line option in selected patients presenting with large or symptomatic pleural effusions in acute care settings Full article

Background/Objectives: Pancreatic fluid collections (PFCs) in acute pancreatitis require drainage when symptomatic or infected. Walled-off necrosis (WON) is difficult to drain with plastic stents alone. A lumen-apposing metal stent (LAMS) offers larger calibre drainage, lower migration risk than conventional methods, and the option of direct endoscopic necrosectomy through the stent. However, the paediatric literature on LAMSs is sparse. We report our institutional experience, and summarise current evidence on the feasibility, efficacy and safety of LAMSs for PFC drainage in children. Methods: We performed a retrospective study at the National University Hospital (NUH) and a full review of the literature on LAMS use in children for endoscopic trans-gastric drainage of PFCs from April 2012 to September 2024. Results: There were, respectively, 2 (males, 10 and 17 years) and 18 children who underwent endoscopic trans-gastric LAMS insertion for drainage of PFCs in acute pancreatitis in the NUH and across the nine included studies, which were published between 2015 and 2024. The technical and clinical success was 100%. There were no complications during insertion or indwell time (28 and 50 days in the NUH and 40 days, range of 7–100 days in the systematic review, respectively). Endoscopic removal of LAMSs was uneventful. There were no recurrent PFCs over a 4-month (1,7 months) and 12-month (range, 2–44 months) follow-up, respectively. Migration of LAMSs to colon following the collapse of the WON was reported in one case. Conclusions: An transgastric LAMS (with trans-stent necrosectomy) is a technically feasible method of drainage of WON following acute pancreatitis in children with minimal complications.

Background/Objectives: Ureteral stents are indispensable tools in contemporary urological practice; however, their prolonged indwelling is frequently associated with a spectrum of complications. This study aims to evaluate the correlation between indwelling duration and the extent of stent encrustation, as well as the impact on extraction difficulty. Methods: A retrospective analysis was conducted on 33 patients treated at Clinical County Emergency Hospital of Brașov between December 2023 and December 2024. All patients had polyurethane double-J ureteral stents placed. Parameters assessed included the degree of stent encrustation, discoloration, incidence of urinary tract infections (UTIs), and extraction difficulty. These were analyzed in relation to indwelling time and patient comorbidities. Statistical processing was performed using SPSS 23.0 software, with significance set at p < 0.05. Results: A statistically significant association was observed between longer stent indwelling times and higher grades of encrustation, particularly for the intervals of 45–90 days and over 90 days (p = 0.008 and p = 0.01, respectively). Low encrustation demonstrated correlations with certain comorbidities, whereas no statistically relevant associations were found for moderate and severe encrustation. Black coloration of the stents was strongly associated with UTIs caused by Escherichia coli, Klebsiella spp., and Enterococcus spp. (p < 0.001), as well as with extended indwelling durations (p < 0.001). No significant correlation was identified between the presence of UTIs and the degree of stent encrustation. Conclusions: Indwelling time is a critical determinant of both ureteral stent encrustation and discoloration, with direct implications for clinical decision-making regarding stent management and extraction planning. Timely removal and close monitoring are essential to reduce the risk of complications associated with long-term stent placement. Full article

Pharmacokinetic studies are critical to assess drug absorption, distribution, metabolism, and excretion in companion animals. Blood collection methods such as direct venepuncture or indwelling catheters could influence pharmacokinetic outcomes and animal welfare. A direct comparison of drug concentrations of two blood sampling methods was investigated in this study to identify any potential differences and their impact on animal welfare. Four canines (male = 3, female = 1) were treated with Apoquel^® (oclacitinib 0.4–0.6 mg/kg) and blood samples were obtained via direct venepuncture into the jugular and a cephalically placed catheter. The drug distribution and cortisol concentration were examined over several time points (0.25, 0.5, 1, 2, 4, and 6 h post treatment). Statistical analysis revealed no significant differences (p > 0.05) in the concentration of the drug between the two collection methods, indicating that both methods are acceptable in generating reliable results for pharmacokinetic data. Nevertheless, cortisol levels indicated a trend suggesting catheter collection may be associated with reduced stress compared to direct venepuncture (Catheter = 201 ± 91; Direct venepuncture = 208 ± 96. This study provides evidence to use a less invasive blood collection such as via a catheter during intensive bleeding schedules that are required in early drug development, thereby improving the overall welfare for the animal.

Urethroplasty is a highly effective surgical treatment for urethral stricture disease. While overall complication rates are low, surgical site infections and urinary tract infections (UTIs) represent the most common complications. Due to the prolonged need for catheterization following reconstruction, many urologists place patients on extended antibiotic prophylaxis postoperatively. However, antibiotic stewardship is important given the risks of antibiotic overuse including opportunistic infections and the emergence of multidrug-resistant organisms. There are currently no established guidelines for the management of antibiotics for patients undergoing urethroplasty, specifically with regard to postoperative prophylaxis through the time of foley catheter removal. In this review, we examine the current literature regarding antibiotic prophylaxis and urethroplasty. Research has shown no clear benefit for extended antibiotic prophylaxis in preventing symptomatic urinary tract infections or stricture recurrence. This is congruent with evidence from other urologic procedures requiring indwelling catheters and/or stents including radical prostatectomy, hypospadias repair, and pyeloplasty. Prospective, randomized trials are needed to further understand the impact of antibiotic prophylaxis on both urethroplasty outcomes and its broader impact on recurrent UTIs and microbial resistance.

Background and Objectives: We aimed to assess the outcomes of upfront Optilume drug-coated balloon (DCB) dilation in patients after failed treatment for complex recurrent urethral stricture disease. All patients presented with acute urinary retention and were treated with DCB dilation regardless of stricture site and length. Materials and Methods: We retrospectively evaluated patients with acute urinary retention and known complex recurrent urethral strictures. Patients presented at the urology emergency room of our tertiary centre with an inability to void or a post-void residual (PVR) volume exceeding 400 mL between August 2021 and February 2024. Urethrography and/or endoscopic imaging confirmed the diagnosis. Patients with urinary tract infection/sepsis and those with neurological disease were excluded. Urethral dilation to 20 Fr was performed, followed by DCB dilation (30 Fr, 10 bar, 10 min). The primary endpoints were anatomical success (≥14 Fr by cystoscopy/calibration) at 12 months and freedom from repeat interventions. Results: Thirty-one consecutive male patients were evaluated, with twenty-six patients followed for ≥12 months (mean age 65 ± 16.8 years). The stricture sites included seven bulbopenile, seven bulbomembranous, seven anastomotic, three bladder neck, one penile, and one panurethral stricture. The median number of prior urethral/surgical interventions was 2 [IQR: 1–3] (range: 1–31). The median stricture length was 3 [IQR: 2–4] cm (range: 1–8). At 12 months, 65.4% (17/26) of subjects voided satisfactorily and were free of recurrence and reoperation. Conclusions: Timely DCB dilation may offer a viable treatment option for patients with complex recurrent urethral strictures and urinary retention, particularly those who are unable or unwilling to undergo surgical reconstruction and prefer to avoid indwelling catheters.

Background and Objectives: This study evaluated the safety and efficacy of long-term indwelling self-expandable covered metallic stents (UVENTA; Taewoong Medical Co., Ltd., Seoul, Republic of Korea) used to manage benign and malignant ureteral strictures. Materials and Methods: We retrospectively identified and analyzed the medical records of all patients who underwent metallic stent insertion at our institution since September 2012. Additionally, we evaluated the technical and clinical success rates and complications of patients who underwent follow-up for more than 36 months. Results: A total of 25 patients underwent metallic stent insertion for ureteral obstructions at our institution. Among them, 18 underwent follow-up for more than 36 months. A total of 21 ureters (15 unilateral and 3 bilateral) were ultimately included in this study. Metallic stents were successfully placed in all ureters using a retrograde approach, with a technical success rate of 100%. The mean follow-up duration was 58.6 months (range, 36–107 months). However, the clinical success rates were 85.7% (18/21 ureters) by 12 months, 61.9% (14/21 ureters) by 24 months, and 52.4% (11/21 ureters) after 36 months. During follow-up, obstructions could not be resolved using metallic stents in eleven ureters (median time to failure, 18.4 months; range, 2−40 months); therefore, they were treated with nephrectomy (three ureters because of a nonfunctional kidney) or percutaneous nephrostomy and double J stent placement (four ureters). Major complications included the encrustation of the metallic stent, flank pain, and gross hematuria. A uretero-enteric fistula occurred in one ureter. In two patients, existing metallic stents were removed and patency was maintained. In another two patients, new metallic stents were inserted without complications. Conclusions: Benign and malignant ureteral obstructions may be treated effectively and safely with metallic stents. However, the patency rate drastically decreased and major complications occurred during long-term follow-up. Therefore, careful patient selection is necessary to achieve better results. Full article

Background and Objectives: Robot-assisted extravesical ureteral reimplantation (REVUR) has been described as valuable alternative to open reimplantation in the pediatric population. This study aimed to report the outcome of REVUR in children with complex obstructed megaureter (COM) needing ureteral dismembering and/or tapering. Materials and Methods: The records of patients with COM, who received REVUR with ureteral dismembering and/or tapering over the last 3 years (2021–2024), were retrospectively reviewed. The inclusion criteria for COM included previous surgery, paraureteral diverticula, or ectopic megaureter. Results: A total of 16 patients (15 boys), with a median age of 7.8 years (range 2–16), were treated over the study period. COM was associated with paraureteral diverticula (n = 6), previous failed endoscopic balloon dilation (n = 4), ectopic megaureter (n = 2), and previous bulking agent endoscopic injection causing iatrogenic ureteral obstruction (n = 4). Presentation symptoms included febrile urinary tract infections (n = 8), flank pain (n = 4), hematuria (n = 2), and pseudo-incontinence (n = 2). All surgical procedures were accomplished robotically without conversions or intra-operative complications. Ureteral tapering was performed in 7/16 (43.7%). The median operative time (including robot docking) was 220 min (range 155–290). The median length of stay was 3.8 days (range 3–7). The indwelling double J stent was removed 4–6 weeks postoperatively. Clavien 2 grade complications occurred postoperatively in 2/16 (12.5%). At median follow-up of 34.5 months, all patients were asymptomatic and showed improved hydroureteronephrosis on ultrasound and improved drainage on diuretic renogram. Conclusions: This study demonstrates that robot-assisted extravesical ureteral reimplantation is a safe and effective treatment for primary obstructive megaureter and other complex ureteral anomalies in our patient cohort. The procedure showed low complication rates, high success rates, and favorable long-term outcomes, supporting the feasibility and effectiveness of robotic surgery for these conditions. Full article

Background: Upper extremity deep vein thrombosis (UEDVT) is uncommon but not insignificant. The current literature is limited, and the management is largely extrapolated from the treatment of lower extremity DVTs (LEDVT). Methods: A retrospective review was conducted on patients diagnosed with UEDVT at Northern Health, Victoria, Australia, between December 2010 and December 2022. Medical records were reviewed to assess baseline characteristics and treatment outcomes. The results were compared to our previously collected data for LEDVTs. Results: 137 patients with UEDVT were identified (52.6% females; median age 62 years, IQR 46–74 years). A total of 105 patients (76.6%) had at least one provoking factor at the time of diagnosis, most commonly malignancy (45.7%) and/or indwelling venous devices (58.1%). Fourteen patients (10.1%) were subsequently diagnosed with Paget–Schroetter syndrome, with nine receiving endovascular or surgical intervention. A total of 109 patients (79.6%) received limited therapeutic anticoagulation (median 3 months, IQR 1.5–6.0 months) with enoxaparin, the most common anticoagulant used. Six patients had major bleeding (5.2/100-patient-years), and seven developed clot progression while on anticoagulation (6.0/100-patient-years). Ten patients had recurrent VTE following anticoagulation cessation (4.6/100-patient-years). There were no significant differences seen in the complication rate between catheter-related UEDVT and other UEDVTs. Compared to LEDVT, UEDVT was more likely provoked with comparable complication rates. Conclusions: UEDVTs were commonly associated with a provoking factor, with indwelling catheters and/or malignancies being the most common. Interestingly, catheter-related UEDVT had comparable clot progression/recurrence and major bleeding compared to other UEDVTs and LEDVTs, which may be confounded by relatively high rates of malignancy.

Pyelo-hepatic abscess is a rare complication of upper urinary tract infections (UTIs). We describe a case of polymicrobial pyelo-hepatic abscess in an immunocompetent patient. A 71-year-old male patient with a double-J stent for right ureteral lithiasis was admitted in our Infectious Diseases Department for a pyelo-hepatic abscess. Despite a targeted antibiotic therapy against an extended spectrum betalactamase-negative Escherichia coli, the patient did not improve. Further examinations revealed a possible polymicrobial aetiology, including Candida spp. and E. coli resistant to piperacillin/tazobactam but sensitive to third-generation cephalosporins. To date, a paucity of articles regarding pyelo-hepatic abscess exist, consisting mostly of case reports. Urinary stones and a ureteral stent indwelling time exceeding 90 days are known risk factors for upper UTIs and for bacterial dissemination in contiguous organs. Pyelo-hepatic abscesses usually involve Gram-negative bacilli, but they can be polymicrobial, including fungi. As a range of factors could limit the efficacy of antibiotics inside an encapsulated lesion and might contribute to the selection of resistant species during treatment, clinicians should be aware of this complication and try to prevent this event by acting on the main modifiable risk factor.

Ranked high in worldwide growing health issues, pleural diseases affect approximately one million people globally per year and are often correlated with a poor prognosis. Among these pleural diseases, malignant pleural mesothelioma (PM), a neoplastic disease mainly due to asbestos exposure, still remains a diagnostic challenge. Timely diagnosis is imperative to define the most suitable therapeutic approach for the patient, but the choice of diagnostic modalities depends on operator experience and local facilities while bearing in mind the yield of each diagnostic procedure. Since the analysis of pleural fluid cytology is not sufficient in differentiating historical features in PM, histopathological and morphological features obtained via tissue biopsies are fundamental. The quality of biopsy samples is crucial and often requires highly qualified expertise. Since adequate tissue biopsy is essential, medical or video-assisted thoracoscopy (MT or VATS) is proposed as the most suitable approach, with the former being a physician-led procedure. Indeed, MT is the diagnostic gold standard for malignant pleural pathologies. Moreover, this medical or surgical approach can allow diagnostic and therapeutic procedures: it provides the possibility of video-assisted biopsies, the drainage of high volumes of pleural fluid and the administration of sterile calibrated talcum powder under visual control in order to achieve pleurodesis, placement of indwelling pleural catheters if required and in a near future potential intrapleural therapy. In this context, dedicated diagnostic pathways remain a crucial need, especially to quickly and properly diagnose PM. Lastly, the interdisciplinary approach and multidisciplinary collaboration should always be implemented in order to direct the patient to the best customised diagnostic and therapeutic pathway. At the present time, the diagnosis of PM remains an unsolved problem despite MDT (multidisciplinary team) meetings, mainly because of the lack of standardised diagnostic work-up. This review aims to provide an overview of diagnostic procedures in order to propose a clear strategy. Full article

Background and Objectives: Endoscopic biliary plastic stenting is a safe and effective temporary therapeutic modality used in various benign biliary disorders. Long-term indwelling stents for more than one year without retrieval are termed “forgotten biliary stents”. In clinical practice, the forgotten stents are underestimated and the majority of data were obtained from case reports. The aim of this study was to determine the forgotten-biliary-plastic-stent-related complications, their management, and the patients’ clinical outcomes. Materials and Methods: This retrospective study was performed at three hospitals during the period from January 2021 to December 2023. In total, 577 patients with biliary plastic stents—inserted for a variety of benign biliary conditions—were included. They were divided into two groups, as follows: group 1 included 527 patients who had biliary stents removed within 3 months, and group 2 included 50 patients with biliary stents retrieved after one year of their deployment. The stent-related complications (e.g., acute cholangitis, stent clogging, distal stent migration, new common bile duct (CBD) stone formation, and proximal stent migration) and the endoscopic management success rate were evaluated. Results: Irretrievable CBD stones were the main indication for biliary plastic stenting in both groups. The stent-related complications, number of endoscopic sessions, and hospital admissions were significantly higher in the patients with forgotten biliary stents than those with stent removal within 3 months. All the study patients were successfully managed endoscopically with uneventful outcomes. Conclusions: Based on this retrospective study, non-adherence to the endoscopists’ instructions is the main reason for retained biliary stents for more than one year. The patients with forgotten stents had significantly higher complication rates, a higher number of endoscopic sessions, and a higher number of hospital admissions than those with stents that were retrieved in the scheduled time. All patients were managed endoscopically with a technical success rate of 100%, and with no complication-related mortality. Full article

The management of ureter hydronephrosis and urolithiasis during pregnancy has been changed by the adoption of ureteric stents. Despite their broad use for several other conditions, from emergency to elective settings, their complications cannot be ignored. Being most prevalent during pregnancy, urinary tract infections and stent encrustations are particularly common and can affect either fetal growth or maternal–fetal homeostasis, leading to obstetric complications. The main concern associated with ureteric stents is the indwelling time, which could represent the potential trigger of those complications. However, to ensure the optimal management of a ureteric stent during pregnancy, factors such as the grading of encrustations and the presence, size, and location of stones should be evaluated in pre-operative planning. As a consequence, a multimodal approach, including obstetrics, gynecologists, urologists, and nurses, is essential to ensure a complication-free procedure and successful ureteric stent removal. Finally, future research should focus on utilizing biodegradable and biocompatible materials to reduce and even eliminate the complications related to forgotten stents in order to reduce the financial burden associated with stent replacement and the management of stent-encrustation-related complications.
