Abstract
Navigating antibiotics at the end of life is a challenge for infectious disease (ID) physicians who remain deeply committed to providing patient-centered care and engaging in shared decision making. ID physicians, who often see patients in both inpatient and outpatient settings and maintain continuity of care for patients with refractory or recurrent infections, are ideally situated to provide guidance that aligns with patients' goals and values. Complex communication skills, including navigating difficult emotions around end-of-life care, can be used to better direct shared decision making and assist with antibiotic stewardship.

A comparison of adverse pregnancy events between ureteral stents and percutaneous nephrostomy tubes in the treatment of nephrolithiasis during pregnancy: A propensity score-matched analysis of a large multi-institutional research network. World J Urol 2023; 41:1721-1726. [PMID: 35909212 DOI: 10.1007/s00345-022-04111-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2022] [Accepted: 07/18/2022] [Indexed: 12/01/2022] Open
Abstract
PURPOSE To investigate rates of adverse pregnancy events associated with the use of percutaneous nephrostomy tubes (PCN) versus ureteral stents in the treatment of nephrolithiasis during pregnancy. METHODS We queried the TriNetX Diamond Network database to evaluate pregnant women (ICD-10 Z34, O09) with a history of nephrolithiasis (N20-23) who underwent a PCN (CPT 50432) or ureteral stent (52332) placement up to 6 months before delivery (O80-82). We controlled for the following potentially confounding variables through propensity score matching: age, race, ethnicity, acute pyelonephritis (N10), infections of the genitourinary tract in pregnancy (O23.0), and other sepsis (A41) at the time of stent or PCN placement. RESULTS We identified 2,999 pregnant women who underwent ureteral stent placement and 321 who underwent PCN. Following propensity score matching, we found there to be no significant difference in the rate of premature labor or delivery (aOR 1.08, 95% CI 0.735-1.588), premature rupture of membranes (0.889, 0.453-1.743), intrauterine infection (0.906, 0.379-2.165), or c-Sect. (0.825, 0.408-1.667). Within 6 months of their initial procedure, women with a ureteral stent experienced a significantly decreased rate of subsequent urinary tract infection (UTI) or pyelonephritis (0.52, 0.38-0.71), inpatient hospital stay (0.40, 0.26-0.64), emergency department visit (0.65, 0.48-0.89), and repeat exchange procedure (0.70, 0.51-0.96). CONCLUSION In the treatment of nephrolithiasis during pregnancy, PCN versus ureteral stent placement does not confer a significant difference in rates of adverse pregnancy events. However, ureteral stent placement was associated with a lower incidence of hospital admissions, emergency department visits, exchange procedures, and new UTIs or pyelonephritis.

Abstract
Over the past several years, multifaceted advances in the management of cancer have led to a significant improvement in survival rates. Throughout patients' oncological journeys, they will likely receive one or more implantable devices for the administration of fluids and medications as well as management of various comorbidities and complications related to cancer therapy. Infections associated with these devices are frequent and complex, often necessitating device removal, increasing health care costs, negatively affecting quality of life, and complicating oncological care, usually leading to delays in further life-saving cancer therapy. Herein, the authors comprehensively review multiple evidence-based recommendations along with best practices, expert opinions, and novel approaches for the prevention of diverse device-related infections. The authors present many general principles for the prevention of these infections followed by specific device-related recommendations in a systematic manner. The continuous involvement and meaningful cooperation between regulatory entities, industry, specialty medical societies, hospitals, and infection control-targeted interventions, along with primary care and consulting health care providers, are all vital for the sustained reduction in the incidence of these preventable infections.

Abstract
Introduction: Infections associated with catheter in the upper urinary tract (CUUT), which include the double-J stent and the percutaneous nephrostomy (PCN) tube, get particularly infected in patients with specific risk factors for developing an infection. Methods: A retrospective observational study was carried out by compiling data from the hospital information system of a tertiary care center from 2019 to 2021 to evaluate infections in patients with catheter in the upper urinary tract. Result: A total of 200 pus samples of double-J stent (96 pus samples) and PCN tube (104 pus samples) were included in our study. Among patients with nephrostomy tube, the most frequently isolated microorganisms were Escherichia coli, followed by Pseudomonas spp. In those with a double-J stent, Pseudomonas aeruginosa, followed by E. coli were the most commonly isolated microorganisms. We found 55.72% of cases of Enterobacteriaceae-producing carbapenemases in patients with a percutaneous catheter. 66.07% of Enterobacteriaceae in patients with double-J and nephrostomy stents are extended-spectrum beta-lactamase-producing bacteria. The percentage of cultures with multiple-drug resistance (MDR) microorganisms was 38.54% in patients with double-J stents and 37.75% in nephrostomy tubes. The presence of prior urinary tract infection (P = 0.010), presence of urinary catheter before admission (P = 0.005), increased time with single urinary catheter in-situ (P < 0.001), and increased length of hospital stay (P = 0.036) were risk factors for isolation of MDR microorganisms. Conclusion: Pseudomonas spp. and Pseudomonas aeruginosa are commonly infecting both the CUUT. E. coli infections are more commonly infecting the nephrostomy tubes. MDR microorganisms are frequent, mainly in patients with prior urinary tract infection, presence of urinary catheter before admission, and prolonged use of a single catheter.

Arch Ital Urol Androl 2022; 94:91-96. [PMID: 35352533 DOI: 10.4081/aiua.2022.1.91] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2022] [Accepted: 03/14/2022] [Indexed: 11/23/2022] Open
Abstract
OBJECTIVE The aim of the present study was to examine the results of antegrade JJ stent placement in upper urinary tract obstruction in patients where retrograde placement was not possible. METHODS In this retrospective study, patients who underwent antegrade JJ stent placement for malignant ureteral obstruction in the urology clinic of a university hospital between January 1, 2018 and December 31, 2020 were included in the study. JJ stent was placed under local or general anaesthesia guided by ultrasonography and fluoroscopy. Age, gender, kidney function values, pathologies causing obstruction, and complications of the patients were examined. RESULTS In this study, 40 patients (16 men, 24 women) who underwent antegrade JJ stent placement were included. The mean ages of the women and men included were 51 (31-91) years and 62.5 (26-81) years, respectively. In all, antegrade JJ stenting was performed in 61 renal units of these patients. Of these, 21 were bilateral, 11 in the right collecting system and 8 in the left collecting systems. Clinical and technical success was achieved in 59 of the 61 procedures (96.6%). Arteriovenous fistula developed in only one patient, whereas no serious complications such as massive bleeding, resistant hematuria or pseudoaneurysm occurred in the remaining patients. The procedure was completed in a mean time of 15-30 minutes. CONCLUSIONS Antegrade JJ stent placement is a procedure with a high success rate and low risk of complications that can be used in patients with severe ureteral obstruction owing to malignant or benign aetiologies. This method should be applied in centres experienced in malignant ureteral obstruction and on patients where retrograde placement was not possible. Furthermore, it should be considered as an alternative treatment option to open surgery as it can be performed under local anaesthesia in patients at a high risk of anaesthesia.

Abstract
Cancer patients are at an increased risk of developing infections that are primarily treatment-driven but may also be malignancy-driven. While cancer treatments such as chemotherapy, radiotherapy, and surgery have been known to improve malignancy morbidity and mortality, they also have the potential to weaken immune defenses and induce periods of severe cytopenia. These adverse effects pave the way for opportunistic infections to complicate a hospitalized cancer patient's clinical course. Understanding the risk each patient inherently has for developing a bacterial, fungal, or viral infection is critical to choosing the correct prophylactic treatment in conjunction with their scheduled cancer therapy. This review discusses the most common types of infections found in hospitalized cancer patients as well as the current guidelines for prophylactic and antimicrobial treatment in cancer patients. In addition, it describes the interaction between antibiotics and cancer therapies for consideration when treating infection in a cancer patient.

Abstract
Infections represent a significant cause of morbidity and mortality in cancer patients. Multiple factors related to the patient, tumor, and cancer therapy can affect the risk of infection in patients with solid tumors. A thorough understanding of such factors can aid in the identification of patients with substantial risk of infection, allowing medical practitioners to tailor therapy and apply prophylactic measures to avoid serious complications. The use of novel treatment modalities, including targeted therapy and immunotherapy, brings diagnostic and therapeutic challenges into the management of infections in cancer patients. A growing body of evidence suggests that antibiotic therapy can modulate both toxicity and antitumor response induced by chemotherapy, radiotherapy, and especially immunotherapy. This article provides a comprehensive review of potential risk factors for infections and therapeutic approaches for the most prevalent infections in patients with solid tumors, and discusses the potential effect of antibiotic therapy on toxicity and efficacy of cancer therapy.

Abstract
Objective To present our clinical experience with percutaneous antegrade ureteral
stenting. Materials and Methods This was a single-center retrospective study in which we reviewed the
electronic medical records of patients who underwent percutaneous
image-guided antegrade ureteral stenting between January 2016 and August
2020. We evaluated 90 patients (48 men). The mean age was 61.4 ± 15
years (range, 30-94 years). Patients were divided into two main groups:
those with malignant neoplasms; and those with non-neoplastic disease.
Technical and clinical success of the procedure were defined, respectively,
as maintenance of the patency of the urinary tract, with a reduction in the
degree of hydronephrosis, and as a reduction in the level of nitrogenous
waste. Postprocedural complications were categorized as major or minor
according to the CIRSE classification. Results The study sample comprised 150 antegrade stenting procedures performed in 90
patients, most of whom had previously undergone retrograde stenting that was
unsuccessful. The stenting was bilateral in 60 patients and unilateral in
30. Technical success was achieved in 143 (95.3%) of the procedures, whereas
seven procedures (4.6%) were unsuccessful. Failed procedures were
characterized by inability to place a stent or migration of a stent after
its placement. Complications occurred in 12 (8.0%) of the procedures. Of
those 12 complications, two were classified as major (bleeding) and 10 were
classified as minor (lumbar pain or infection). The most common techniques
used were the over-the-wire technique and the modified technique (in 58.0%
and 42.0% of the cases, respectively). In seven cases (4.7%), a nephrostomy
tube was inserted. Conclusion Percutaneous antegrade ureteral stenting is a safe, effective method for the
management of ureteral injuries and obstructions, due to malignant or benign
causes, when the retrograde approach has failed.

Abstract
Background: The acute care surgery model has led to improved outcomes for emergent surgical conditions, but similar models of care have not been implemented in urology. Our department implemented an acute care urology (ACU) service in 2015, and the service evolved in 2018. We aimed to evaluate the impact of the ACU model on the management of nephrolithiasis. Materials and Methods: We conducted a retrospective review of all patients with urology consults in the emergency department for nephrolithiasis, who required surgical intervention from 2013 to 2019. Patients were divided into three cohorts based on date of consultation: Pre-ACU (2013-2014), Phase 1 (2015-2017), and Phase 2 (2018-2019). Results: We identified 733 patients with nephrolithiasis requiring intervention (162 pre-ACU, 334 Phase 1, and 237 Phase 2). Before ACU implementation, median time from consult to definitive intervention was 36 days. After ACU implementation, median time to intervention decreased to 22 days in Phase 1 (p < 0.001) and 15 days in Phase 2 (p < 0.001). On multivariable Cox regression, the hazard of definitive intervention improved in Phase 1 (hazard ratio [HR] 1.90, p < 0.001) and in Phase 2 (HR 1.80, p < 0.001). Rates of primary definitive intervention without initial decompression and loss to follow-up were also significantly improved, compared to the pre-ACU cohort. Conclusions: Implementation of a structured ACU service was associated with improved time to treatment for patients with acute nephrolithiasis, as well as increased primary definitive intervention and improved follow-up care. This model of care has potential to improve patient outcomes for nephrolithiasis and other acute urological conditions.

Abstract
BACKGROUND Nephrostomy tubes are commonly placed for urinary obstruction, urinary diversion, or future endourologic procedures. While the technical success of nephrostomy tube placement is high, nephrostomy tube complications may occur. OBJECTIVE OF REVIEW Limited literature exists regarding the complication of nephrostomy tubes and their approach in the emergency department. This review summarizes the existing literature and provides a framework for emergency providers regarding the evaluation and management of nephrostomy tube complications. DISCUSSION Nephrostomy tube failure, caused by kinking, dislodgment, or migration can manifest with obstructive signs and symptoms. In well appearing patients, asymptomatic bacteriuria is common and should not be treated. However, in the presence of infectious symptoms, patients should be treated similarly to complicated cystitis or pyelonephritis. While gross hematuria is common following catheter placement, prolonged hematuria, or the return of hematuria after previous resolution should trigger investigation for hematoma formation or a delayed presentation of an intraoperative vascular injury. Finally, clinicians should obtain laboratory testing, advanced imaging, and specialty consultation if serious complications are suspected. CONCLUSION This narrative review highlights general nephrostomy tube care, minor complications, and troubleshooting in the emergency department. The majority of these minor complications can be managed at the bedside without specialty consultation. However, in patients with more serious complications including dislodgement, obstruction, infection, bleeding, and pleural injury, laboratory assessment and advanced imaging to include ultrasound and computed tomography with specialty consultation are essential in the patient's evaluation and management, particularly in cases of immune compromise and worsening renal function.

Abstract
Infections are the most commonly encountered complications in patients with cancer. The classical signs and symptoms of infections are often not present in this patient population, which makes the diagnosis more challenging. Host factors play a major role in the development and prognosis of infections in cancer patients; these can be related to the underlying type of malignancy (solid organ versus hematological), tumor burden, anatomic obstruction, altered integrity of barriers (skin or mucosa), treatment-related factors (from chemotherapy, radiation treatment, surgery, interventional procedures, and/or medical device placement) and the degree of immunosuppression. This article reviews common, as well as less common, imaging manifestations of infections and their potential mimics in the abdomen and pelvis in cancer patients and discusses their differentiating features, with the role of imaging in various organs in the abdomen and pelvis taking into consideration relevant clinical background information and the main risk factors.

Abstract
OBJECTIVE To determine the potential predictors of antegrade ureteral stenting (AUS) failure in patients with malignant and benign ureteral obstruction. METHOD We retrospectively evaluated 116 AUS procedures performed in 80 patients for ureteral obstruction due to malignant and benign causes. Variables such as etiology for obstruction, ureter shape, previous treatment regimen, history of ileal loop diversion, and presence of percutaneous nephrostomy were recorded. Univariate and multivariate logistic regression methods were used between these variables and stent failure. RESULTS Antegrade ureteral stenting was performed as single stage in 24 procedures (n: 24/116, 21%) and performed as a two-step approach after percutaneous nephrostomy in 92 procedures (n: 92/116, 79%). Ureteral stent was successfully deployed in 112 AUS procedures (n: 112/116, 96.5%). In 35 of these successful procedures, the patients were referred to our department due to prior failed retrograde ureteral stenting (RUS). Subsequent stent failure occurred in 40 procedures after a median interval of 39 days. Pre-stenting percutaneous nephrostomy (PN) was a statistically significant risk factor for stent failure (p: 0.041), and age showed an inverse relationship with stent failure (p: 0.008). Complications in early (within the first 30 days after procedure) and late stage occurred in a total of 17 procedures. Early complications included urinary tract infection (n: 11), stent migration (n: 3), and malposition (n: 1). Late complications (after 30 days) were urinary tract infection (n: 1) and stent migration (n: 1). CONCLUSION This study suggests that AUS can be performed effectively in both benign and malignant ureteral obstructions including cases with prior failed RUS. Two-step AUS after percutaneous nephrostomy was found to be a significant risk factor for subsequent stent failure in our study cohort.

Abstract
Critically ill patients with cancer are vulnerable to infections because of the underlying malignancy, tumor-directed therapy, immunosuppression, breaches in mucosa or skin, malnutrition, and other factors. Neutropenia remains the most important risk factor for infection. Infectious complications occurring in critically ill patients with cancer can affect the bloodstream, lungs, gastrointestinal tract, central nervous system, urinary tract, and the skin. Pneumonias are the leading cause of infection in patients with cancer admitted to the intensive care unit. Consideration of opportunistic pathogens in the differential diagnosis is important in patients with impaired cellular and/or humoral immunity or compromised splenic function.

An Observational Cohort Study Investigating the Incidence Rate of Infectious Complications After Routine Office Nephrostomy Tube Replacement Without Using Antimicrobial Prophylaxis. Urology 2020; 147:27-32. [PMID: 33169689 DOI: 10.1016/j.urology.2020.10.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2020] [Revised: 09/26/2020] [Accepted: 10/14/2020] [Indexed: 11/20/2022]
Abstract
OBJECTIVE To investigate the incidence of infectious complications after routine office nephrostomy tube replacement (NTR) in patients that did not receive antimicrobial prophylaxis (AMP). METHODS We prospectively enrolled all patients undergoing routine office NTR between July 2018 and September 2019. Each procedure was considered an independent event. Clinical, microbiological, demographic data were collected. AMP was exclusion criterion. All patients received a questionnaire via phone call within 3 weeks after NTR investigating fever, antibiotics use, hospital admissions. Infectious complications risk was assessed with univariate and multivariate binomial logistic regression analysis. RESULTS One hundred forty-five routine NTRs were performed. Nineteen patients receiving AMP were excluded. Median age was 78 years (interquartile range 71-81). Charlson Comorbidity Index (CCI) score was ≥5 in 53.2% of patients, 34 had positive urine culture, none received AMP. Seventeen (13.49%) patients reported fever after procedure, 9 received antibiotic therapy while fever resolved spontaneously in 8. Three patients needed hospitalization, 2 for nephrostomy malfunction, 1 for infectious complications. At multivariate analysis only CCI score ≥3 was associated (P < .001) with increased infectious complications risk. CONCLUSION In this study fever occurs after the 13.5% of the routine NTRs, in almost half cases resolves spontaneously rather than with oral antimicrobial therapy. Avoiding AMP before routine NTR does not expose patients to life-threatening infections.

Abstract
PURPOSE We aimed to evaluate the long-term complications and predisposing factors for these complications in patients with malignant ureteral obstruction (MUO) treated with percutaneous nephrostomy (PN). METHODS The records of patients with MUO treated with PN between January 2015 and 2018 were retrospectively reviewed for PN dislodgement, PN obstruction, PN replacement, pyelonephritis, hospitalizations due to PN complications, and other complications due to PN such as macroscopic hematuria, skin infections, or renal/perirenal abscess. RESULTS Data for a total of 147 patients (229 renal units [RU], 107 males, 40 females) were evaluated. In 174 (76%) RU, PN was replaced due to PN dislodgement. The predisposing factors for PN dislodgement were follow-up time, body mass index (BMI), chemotherapy, diabetes mellitus (DM), low educational level (LEL), pyelonephritis, and catheter-related skin infections (CSRI). The PN was replaced in 40 RU due to obstruction. The predisposing factors for obstruction were follow-up time and BMI. Pyelonephritis developed at least once in 61 (41.5%) patients. Follow-up time, BMI, previous surgery, DM, and LEL were the predisposing factors for pyelonephritis. CSRI developed in 16 RU. Follow-up time, BMI, DM, and LEL were the predisposing factors for CSRI. Macroscopic hematuria developed in 11 patients. Follow-up time, previous surgery, DM, chemotherapy, and LEL were predisposing factors for macroscopic hematuria. CONCLUSION The most common complication in patients with MUO treated with PN was PN dislodgement. However, life-threatening complications such as macroscopic hematuria and severe infections can also occur. Patients with DM, LEL, and chemotherapy are at high risk of PN-related complications.

Abstract
Background: Antibiotic prophylaxis is usually adopted to prevent urinary tract infection (UTI) after nephrostomy catheter placement and replacement. This prophylaxis has been little studied in cancer patients, and its efficacy is uncertain. Objective: To determine the rate of UTI associated with percutaneous nephrostomy catheters placement and replacement and associated risk factors. Methods: This retrospective study collected data from the available medical records. Catheter-related UTI was defined as any diagnosis of UTI based on clinical symptoms recorded in antibiotic prescription charts, and on the results of urine culture collected up to 7 days after percutaneous nephrostomy catheter. The associations between categorical variables were analyzed using Fisher's exact test. The risk factors for UTI were assessed using logistic regression. Results: In the univariate analyses, there was no significant difference in the rate of urinary infection between patients receiving and not receiving antibiotic prophylaxis before percutaneous nephrostomy and after replacement. Conclusion: The results of the present study suggest that the use of antibiotic prophylaxis for managing urinary tract obstruction by percutaneous nephrostomy is not recommended in cancer patients. In contrast, for catheter replacement, antibiotic prophylaxis appears to have a protective effect for UTI.

Abstract
Introduction Percutaneous nephrostomy (PCN) is a commonly performed intervention in urology for various benign and malignant conditions causing upper urinary tract obstruction. We present a prospective audit of complications of ultrasonography (USG) guided PCN using modified Clavien classification system (mCCS). Methods The data were prospectively collected for 368 PCN performed in 344 patients from June 2015 to January 2017, for various benign and malignant diseases causing upper urinary tract obstruction. Patients were followed for 1 month, and complications arisen of PCN were noted. Results PCN was successful in 356 renal units. The 12 patients in which PCN failed was due to minimal pelvicalyceal dilatation and PCN was successfully performed after 48 h by a senior urologist. 207 patients had malignant disease and 161 patients had benign condition. Most common malignant disease was carcinoma cervix. 238 were noninfected while 130 had infected renal units. 62 (16.84%) patients had Grade I (self-limiting hematuria/cot/debris/fever). 37 (10.0%) patients had Grade II (7 - transfusion and 30 - urinary tract infection). 34 (9.2%) had Grade III a (repositioning/change/reinsertion of PCN tube under local anesthesia) and 4 (1.1%) had Grade III b (repositioning under anesthesia). 8 (2.2%) Grade IV a (Sepsis), 0 Grade IV b, and 0 Grade V complications were observed. Conclusion USG-guided PCN is a safe, minimally invasive, and effective procedure for upper urinary tract diversion with a low rate of morbidity. Individual complications are within the threshold limits set by the American College of Radiology, the Society of Interventional Radiology. mCCS is well applicable and easily reproducible tool for reporting the complications of PCN.

Abstract
We report two cases of complicated Urinary Tract Infection, one with nephrostomy tube left in-situ and other with bladder outlet obstruction, caused by Trichosporon loubieri. Both patients responded well to antifungal treatment along with change/removal of catheters. In both the cases, correct identification of T. loubieri was done by IGS1 sequencing. Prompt identification and timely management headed to good clinical outcome. Hence, clinicians should be aware of T. loubieri as an emerging fungi causing human infections.

Abstract
PURPOSE There are few published reviews that have assessed the clinical utility of renal urine cultures following percutaneous nephrostomy (PCN). In this systematic review, we evaluated the published evidence of the clinical utility of nephrostomy urine cultures in the light of emerging antimicrobial resistance and need for stewardship. METHODS We performed a systematic literature search and review for evidence on the utility and role of nephrostomy urine cultures, using Medline, Embase and PubMed. We looked for evidence to assess whether there is any utility in collecting renal urine for culture at the time of percutaneous nephrostomy (PCN) and if the culture results of nephrostomy urine and bladder urine are different. We studied outcomes of treatment based on nephrostomy culture results. We also examined the role of PCN cultures at the time of routine nephrostomy exchange. Finally, we assessed if doing a PCN leads to infection or pyelonephritis. RESULTS From 94 studies initially identified, we finally selected two randomised clinical trials (RCT), six original articles and five detailed conference abstracts for the review. These studies suggest that PCN urine cultures are overall useful in clinical practice. They are useful in selecting appropriate antimicrobial treatment for urosepsis following upper urinary obstruction. There does not appear to be any advantage in performing PCN cultures at routine nephrostomy exchanges. Occasionally, PCN itself can lead to subsequent urosepsis. CONCLUSION Nephrostomy urine cultures have utility in clinical practice and can help support treatment and antimicrobial stewardship.

Abstract
PURPOSE Percutaneous nephrostomy (PCN) catheters are mainly indicated for urinary tract obstructions. Unfortunately, the rate for infection and recurrence remains elevated. Our objective was to identify the risk factors leading to recurrent PCN-related infections (PCNI) in cancer patients. METHODS We retrospectively reviewed 571 patients who underwent initial PCN catheter placement at our institution. Of these, we identified patients with a definite PCNI and catheter exchange, with a minimum 30-day follow-up. We defined PCNI as presence of a urine culture positive for bacteria (≥ 104 CFU/mL) plus symptoms of urinary tract infection. A PCNI was considered recurrent if the same organism was isolated. Antibiotics were considered concordant if they were active against all identified organisms. RESULTS A total of 81 patients (14%) developed an initial PCNI. Of 47 patients with 30-day follow-up, 10 patients (21%) were identified as having a recurrent PCNI. In terms of demographic characteristics, clinical manifestations, and microbiological data, there was no statistically significant difference between the recurrent and non-recurrent groups. However, in multivariate logistic regression analysis, two factors were independently associated with a decrease in recurrent PCNI: concordant antibiotic use (OR 0.04; p = 0.008) and PCN catheter exchange within 4 days of infection (OR 0.1; p = 0.048). CONCLUSIONS To decrease the high rate of recurrent infections, associated costs, and potential delay in further chemotherapy, we recommend that once antimicrobial susceptibility test results are available and the patient is known to be receiving concordant antimicrobials, clinicians proceed with immediate PCN catheter exchange, ideally within the first 4 days of the infection.

Abstract
Hospital-acquired infections are a common and costly problem facing critically ill patients in the intensive care unit (ICU). Critically ill patients with cancer are a particularly vulnerable subpopulation who possesses additional, nonmodifiable risk factors for developing these infections and, in many cases, are at increased risk of death as a result. This review will describe the most common nosocomial infections patients with cancer acquire while in the ICU: ventilator-associated events, central line-associated bloodstream infection, catheter-associated urinary tract infections, and Clostridium difficile infection.

Abstract
OBJECTIVES The aim of this study was to compare single and tandem ureteral stenting in the management of malignant ureteral obstruction (MUO). METHODS Our hospital's institutional review board approved this prospective study. Between November 2014 and June 2017, single ureteral stenting was performed in 56 patients (94 renal units) and tandem ureteral stenting in 48 patients (63 renal units) for MUO. A comparative analysis of the technical success rate, patient survival, stent patency, and complications was performed. RESULTS Similar demographic data were observed in patients receiving either single or tandem ureteral stenting. The technical success rate was 93.6% (88/94) for single ureteral stenting and 95.2% (60/63) for tandem ureteral stenting. There was no difference in overall survival between patients receiving single or tandem ureteral stenting (p = 0.41), but the duration of stent patency in tandem ureteral stenting was significantly longer (p = 0.022). The mean patency time was 176.7 ± 21.3 days for single ureteral stenting, and 214.7 ± 21.0 days for tandem ureteral stenting. The complications of ureteral stenting were urinary tract infection (n = 18), lower urinary tract symptoms (n = 5), haematuria (n = 3), and stent migration (n = 1). CONCLUSIONS Tandem ureteral stenting is a safe and feasible treatment for MUO, and had better efficacy compared to single ureteral stenting. KEY POINTS • Ureteral stenting is an established treatment for the management of malignant ureteral obstruction (MUO) • Prospective single-centre study showed that tandem ureteral stenting is a safe and feasible treatment for MUO • Tandem ureteral stenting provides longer stent patency compared to single ureteral stenting in patient with MUO.

Abstract
BACKGROUND/AIMS Double J (JJ) stents for treating obstructive ureteral pathology are generally inserted through a retrograde route with cystoscopic guidance. Antegrade percutaneous insertion using fluoroscopy can be performed alternatively but is less known. Indications, success rate and complications of antegrade ureteral stenting were evaluated. METHODS Data of consecutive patients in which antegrade ureteral stenting was performed were retrospectively analysed using the radiology information system and patient records. Patient characteristics, details of the antegrade JJ stent insertion procedure and registered complications were collected. Furthermore, it was investigated if prior to the antegrade procedure a retrograde attempt for JJ stent insertion was performed. RESULTS Total 130 attempts for antegrade JJ stent insertion were performed in 100 patients. A percutaneous nephrostomy catheter had already been placed in the majority of kidneys (n = 109) for initial treatment of hydronephrosis. Most prevelant indication for a JJ stent was obstructive ureteral pathology due to malignancy (n = 63). A JJ stent was successfully inserted in 125 of 130 procedures. In 21 cases, previous retrograde ureteral stenting had failed but, subsequent antegrade ureteral stenting was successful. There were 8 procedure related complications; 6 infections, 1 false tract and 1 malposition. CONCLUSION Antegrade percutaneous insertion of a JJ stent is a good alternative for retrograde insertion.

In Vitro Study of Antimicrobial Percutaneous Nephrostomy Catheters for Prevention of Renal Infections. Antimicrob Agents Chemother 2017; 61:AAC.02596-16. [PMID: 28320713 DOI: 10.1128/aac.02596-16] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2016] [Accepted: 03/03/2017] [Indexed: 01/28/2023] Open
Abstract
Percutaneous nephrostomy (PCN) catheters are the primary method for draining ureters obstructed by malignancy and preventing a decline of renal function. However, PCN catheter-related infections, such as pyelonephritis and urosepsis, remain a significant concern. Currently, no antimicrobial PCN catheters are available for preventing infection complications. Vascular catheters impregnated with minocycline-rifampin (M/R) and M/R with chlorhexidine coating (M/R plus CHD) have previously demonstrated antimicrobial activity. Therefore, in this study, we examined whether these combinations could be applied to PCN catheters and effectively inhibit biofilm formation by common uropathogens. An in vitro biofilm colonization model was used to assess the antimicrobial efficacy of M/R and M/R-plus-CHD PCN catheters against nine common multidrug-resistant Gram-positive and Gram-negative uropathogens as well as Candida glabrata and Candida albicans Experimental catheters were also assessed for durability of antimicrobial activity for up 3 weeks. PCN catheters coated with M/R plus CHD completely inhibited biofilm formation for up to 3 weeks for all the organisms tested. The reduction in colonization compared to uncoated PCN catheters was significant for all Gram-positive, Gram-negative, and fungal organisms (P < 0.05). M/R-plus-CHD PCN catheters also produced significant reductions in biofilm colonization relative to M/R PCN catheters for Enterobacter spp., Escherichia coli, Pseudomonas aeruginosa, methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci, C. glabrata, and C. albicans (P < 0.05). M/R-plus-CHD PCN catheters proved to be highly efficacious in preventing biofilm colonization when exposed to multidrug-resistant pathogens common in PCN catheter-associated pyelonephritis. M/R-plus-CHD PCN catheters warrant evaluation in a clinical setting to assess their ability to prevent clinically relevant nephrostomy infections.

Abstract
Solid tumors are much more common than hematologic malignancies. Although severe and prolonged neutropenia is uncommon, several factors increase the risk of infection in patients with solid tumors, and the presence of multiple risk factors in the same patient is not uncommon. These include obstruction (most often caused by progression of the tumor), disruption of natural anatomic barriers such as the skin and mucosal surfaces, and treatment-related factors such as chemotherapy, radiation, diagnostic and/or therapeutic surgical procedures, and the increasing use of medical devices such as various catheters, stents, and prostheses. Common sites of infection include the skin and skin structures (including surgical site infections), the bloodstream (including infections associated with central venous catheters), the lungs, the hepato-biliary and intestinal tracts, and the urinary tract, and include distinct clinical syndromes such as post-obstructive pneumonia, obstructive uropathy, and neutropenic enterocolitis. The epidemiology of most of these infections is changing with resistant organisms [MRSA, Pseudomonas aeruginosa, extended spectrum beta-lactamase (ESBL)-producing organisms] being isolated more often than in the past. Polymicrobial infections now predominate when deep tissue sites are involved. Conservative management of most of these infections (antibiotics, fluid and electrolyte replacement, bowel rest when needed) is generally effective, with surgical intervention being reserved for the drainage of deep abscesses, or to deal with complications such as intestinal obstruction or hemorrhage. Infected prostheses often need to be removed. Reactivation of certain viral infections (HBV, HCV, and occasionally CMV) has become an important issue, and screening, prevention and treatment strategies are being developed. Infection prevention, infection control, and antimicrobial stewardship are important strategies in the overall management of infections in patients with solid tumors. Occasionally, infections mimic solid tumors and cause diagnostic and therapeutic challenges.

Abstract
Infectious complications following interventional radiology (IR) procedures can cause significant patient morbidity and, potentially, mortality. As the number and breadth of IR procedures grow, it becomes increasingly evident that interventional radiologists must possess a thorough understanding of these potential infectious complications. Furthermore, given the increasing incidence of antibiotic-resistant bacteria, emphasis on cost containment, and attention to quality of care, it is critical to have infection control strategies to maximize patient safety. This article reviews infectious complications associated with percutaneous ablation of liver tumors, transarterial embolization of liver tumors, uterine fibroid embolization, percutaneous nephrostomy, percutaneous biliary interventions, central venous catheters, and intravascular stents. Emphasis is placed on incidence, risk factors, prevention, and management. With the use of these strategies, IR procedures can be performed with reduced risk of infectious complications.

Abstract
Extrinsic malignant compression of the ureter is not uncommon, often refractory to decompression with conventional polymeric ureteral stents, and frequently associated with limited survival. Alternative options for decompression include tandem ureteral stents, metallic stents and metal-mesh stents, though the preferred method remains controversial. We reviewed and updated our outcomes with tandem ureteral stents for malignant ureteral obstruction, and carried out a PubMed search using the terms "malignant ureteral obstruction," "tandem ureteral stents," "ipsilateral ureteral stents," "metal ureteral stent," "resonance stent," "silhouette stent" and "metal mesh stent." A comprehensive review of the literature and summary of outcomes is provided. The majority of studies encountered were retrospective with small sample sizes. The evidence is most robust for metal stents, whereas only limited data exists for tandem or metal-mesh stents. Metal and metal-mesh stents are considerably more expensive than tandem stenting, but the potential for less frequent stent exchanges makes them possibly cost-effective over time. Urinary tract infections have been associated with all stent types. A wide range of failure rates has been published for all types of stents, limiting direct comparison. Metal and metal-mesh stents show a high incidence of stent colic, migration and encrustation, whereas tandem stents appear to produce symptoms equivalent to single stents. Comparison is difficult given the limited evidence and heterogeneity of patients with malignant ureteral obstruction. It is clear that prospective, randomized studies are necessary to effectively scrutinize conventional, tandem, metallic ureteral and metal-mesh stents for their use in malignant ureteral obstruction.

Abstract
Background Complicated pyelonephritis (cPN), a common cause of hospital admission, is still a poorly-understood entity given the difficulty involved in its correct definition. The aim of this study was to analyze the main epidemiological, clinical, and microbiological characteristics of cPN and its prognosis in a large cohort of patients with cPN. Methods We conducted a prospective, observational study including 1325 consecutive patients older than 14 years diagnosed with cPN and admitted to a tertiary university hospital between 1997–2013. After analyzing the main demographic, clinical and microbiological data, covariates found to be associated with attributable mortality in univariate analysis were included in a multivariate logistic regression model. Results Of the 1325 patients, 689 (52%) were men and 636 (48%) women; median age 63 years, interquartile range [IQR] (46.5-73). Nine hundred and forty patients (70.9%) had functional or structural abnormalities in the urinary tract, 215 (16.2%) were immunocompromised, 152 (11.5%) had undergone a previous urinary tract instrumentation, and 196 (14.8%) had a long-term bladder catheter, nephrostomy tube or ureteral catheter. Urine culture was positive in 813 (67.7%) of the 1251 patients in whom it was done, and in the 1032 patients who had a blood culture, 366 (34%) had bacteraemia. Escherichia coli was the causative agent in 615 episodes (67%), Klebsiella spp in 73 (7.9%) and Proteus ssp in 61 (6.6%). Fourteen point one percent of GNB isolates were ESBL producers. In total, 343 patients (25.9%) developed severe sepsis and 165 (12.5%) septic shock. Crude mortality was 6.5% and attributable mortality was 4.1%. Multivariate analysis showed that an age >75 years (OR 2.77; 95% CI, 1.35-5.68), immunosuppression (OR 3.14; 95% CI, 1.47-6.70), and septic shock (OR 58.49; 95% CI, 26.6-128.5) were independently associated with attributable mortality. Conclusions cPN generates a high morbidity and mortality and likely a great consumption of healthcare resources. This study highlights the factors directly associated with mortality, though further studies are needed in the near future aimed at identifying subgroups of low-risk patients susceptible to outpatient management.

Abstract
The method of diagnosing chronic kidney disease by simple estimated glomerular filtration rate equations has demonstrated a high prevalence of chronic kidney disease among the genitourinary cancer patients. Approximately 30-50% of urothelial cancer patients have Grade 3 chronic kidney disease before chemotherapy, and the rate increases to around 80% in upper urinary tract cancer patients who have undergone radical surgery. Several gold-standard treatments, including cisplatin for urothelial/testicular tumors and anti-vascular endothelial growth factor therapy for kidney cancers, are known to be associated with the development of renal impairment. However, which renal function assessments are best to select a chemotherapy regimen remain unknown. Most testicular tumor patients are cured by intensive combined chemotherapy with cisplatin, but chemotherapy can induce chronic kidney disease in testicular cancer survivors. The prevalence of Stage 3 chronic kidney disease among the testicular cancer survivors is between 10 and 20%. Thus, the estimated glomerular filtration rate assessment is a useful tool for monitoring the development of chronic kidney disease among the cancer survivors, and assessment of renal function is mandatory before the treatment of these genitourinary cancer patients.
