Longitudinal Outcomes of Malignant Ureteral Obstruction Secondary to Ovarian Cancer: Predictors of Resolution and the Role of Surgical Management. Urology 2024; 186:101-106. [PMID: 38350551 DOI: 10.1016/j.urology.2024.02.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Revised: 12/29/2023] [Accepted: 02/01/2024] [Indexed: 02/15/2024]
Abstract
OBJECTIVE To review the management of ovarian cancer (OCa) associated hydronephrosis (HN). Specifically, we aim to identify optimal management of HN in the acute setting, predictors of HN resolution, and the role of surgery (tumor debulking/(+/-)ureterolysis/hysterectomy). MATERIALS/METHODS The study cohort included OCa patients managed at our institution from 2004-2019 that developed OCa-associated HN. Initial HN management was recorded as none, retrograde ureteral stent (RUS) or percutaneous nephrostomy tube (PCN). Primary outcomes included (1) HN management failure, (2) HN management complications, and (3) HN resolution. Patient, cancer, and treatment predictors of outcomes were assessed using logistic regression and fine-Gray competing risk models. RESULTS Of 2580 OCa patients, 190 (7.4%) developed HN. HN was treated in 121; 90 (74.4%) with RUS, 31 (25.6%) with PCN. Complication rates were similar between PCN and RUS (83% vs 85.1%; P = .79; all Clavian Grade I/II). Initial HN treatment failure occurred in 28 patients, predicted by renal atrophy (hazard ratios (HR) 3.27, P <.01). HN resolution occurred in only 52 (27%) patients and was predicted by lower International Federation of Gynecology and Obstetrics (FIGO) stage (FIGO III/IV HR 0.42, P <.01) and surgical tumor debulking/ureterolysis (HR 2.83, P = .02). CONCLUSION Resolution of HN associated with malignant obstruction from OCa is rare and is most closely associated with tumor debulking and International Federation of Gynecology and Obstetrics (FIGO) stage. Initial endoscopic treatment modality was not significantly associated with complications or resolution, though RUS failures were slightly more common. Ureteral reconstruction at time of debulking/ureterolysis is potentially underutilized.

Abstract
Objective To assess if there is a preferable intervention between retrograde ureteral stent (RUS) and percutaneous nephrostomy (PCN) tube, in cases of upper urinary tract stone obstruction with complications requiring urgent drainage, by evaluating outcomes regarding urinary symptoms, quality of life (QoL), spontaneous stone passage, and length of hospital stays, since there is no literature stating the superiority of one modality over the other. Methods We searched MEDLINE and other sources for relevant articles in June 2019 without any date restrictions or filters applied. The selection was done first by the title and abstract screening and then by full-text assessment for eligibility. Only randomized controlled trials or cohort studies in patients with hydronephrosis secondary to obstructive urolithiasis that presented comparative data between PCN and RUS placement concerning at least one of the defined outcome measures were included. Lastly, MEDLINE database and PubMed platform were screened again using the same terms, from June 2019 until November 2022. Results Of 556 initial articles, seven were included in this review. Most works were considered of moderate-to-high quality. Three studies regarding QoL showed a tendency against stenting, even though only one demonstrated statistically significant negative impact on overall health state. Two works reported significantly more post-intervention urinary symptoms in stenting patients. One article found that PCN is a significant predictor of spontaneous stone passage, when adjusted for stone size and location. Findings on length of hospital stays were not consistent among articles. Conclusion PCN appears to be the intervention better tolerated, with less impact on the patient's perceived QoL and less post-operative urinary symptoms, in comparison with RUS. Nevertheless, further studies with larger samples and a randomized controlled design are suggested.

Abstract
Background Malignant ureteral obstruction (MUO) is a common condition that complicates the course of advanced malignancies. The aims of this study are to analyze the causes, management, and survival of patients with obstructive nephropathy due to malignant ureteric obstruction and to determine prognostic factors. Furthermore, we studied the complications and outcomes in patients who underwent urinary diversion. Materials and methods A retrospective study was conducted on patients with computed tomography-confirmed MUO between January 2016 and November 2020. Demographic, clinical, radiological, laboratory, and management data were collected. Survival curves were estimated using the Kaplan-Meier method, and univariate and multivariate Cox proportional hazards models were used to test the association between parameters and survival. Results A total of 188 patients were included. The mean age was 69.01 years (SD, 14.95 years), and the majority (54.8%) were male. The most common mechanism leading to MUO was compression by a pelvic mass (36.9%), and the 3 most frequent tumors causing MUO were prostate (17.6%), bladder (16.5%), and rectal cancer (11.7%).Forty-seven patients (25%) underwent urinary diversion: 23 (48.9%) underwent double-J stenting and 21 (44.7%) underwent percutaneous nephrostomy. The most common reason for urinary diversion was acute kidney injury (53.3%). Recovery of renal function was observed in 55.8% of the patients after urinary diversion. The most frequently identified complications after urinary diversion were urinary tract infection (24.4%), hematuria (17.0%), and urinary sepsis (14.9%). The median survival after hydronephrosis diagnosis was 6.43 months (interquartile range, 1.91-14.81 months). In patients who underwent urinary decompression, the median survival after urinary diversion was 8.67 months (interquartile range, 2.99-17.28 months). In the multivariate analysis, a lower grade of hydronephrosis and cancer cachexia negatively impacted survival. Conclusions Cancer patients with MUO have a poor prognosis; therefore, the risk-benefit ratio of urinary diversion should be carefully considered. Cachexia and hydronephrosis grade can be useful in selecting suitable candidates for urinary diversion.

Abstract
Background The debate regarding the optimal drainage method for acute obstructive upper urinary tract infection persists, focusing on the choice between percutaneous nephrostomy (PCN) and retrograde ureteral stenting (RUS). Aims This study aims to systematically examine the perioperative outcomes and safety associated with PCN and RUS in treating acute obstructive upper urinary tract infections. Methods A comprehensive investigation was conducted using the Medline, Embase, Web of Science, and Cochrane databases up to December 2022, following the guidelines of the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement. The utilized keywords included 'PCN', 'RUS', 'acute upper obstructive uropathy', and 'RCT'. Inclusion criteria encompassed studies providing accurate and analyzable data, which incorporated the total subject count, perioperative outcomes, and complication rates. The assessed perioperative outcomes included fluoroscopy time, normalization of temperature, normalization of serum creatinine, normalization of white blood cell (WBC) count, and operative time. Safety outcomes encompassed failure rate, intraoperative and postoperative hematuria, postoperative fever, postoperative pain, and postoperative nephrostomy tube or stent slippage rate. The study protocol was prospectively registered at PROSPERO (CRD42022352474). Results The meta-analysis encompassed 7 trials involving 727 patients, with 412 assigned to the PCN group and 315 to the RUS group. The outcome of the meta-analysis unveiled a reduced occurrence of postoperative hematuria in the PCN group [odds ratio (OR) = 0.54, 95% confidence interval (CI) 0.30-0.99, p = 0.04], along with a decreased frequency of insertion failure (OR = 0.42, 95% CI 0.21-0.81, p = 0.01). In addition, the RUS group exhibited a shorter fluoroscopy time than the PCN group (mean difference = 0.31, 95% CI 0.14-0.48, p = 0.0004). Conclusion Given the significant impact of hematuria and catheterization failure on postoperative quality of life, the preference for PCN appears more advantageous than RUS.

Abstract
To the Editor, Upper urinary tract obstruction (UUTO) is a common scenario in clinical practice, and it is caused by a variety of diseases. Lithiasis, tumours and strictures are some of the principal aetiologies. Multiple factors may influence both the need for decompression of the obstructed collecting system and the urgency of procedure...

Abstract
PURPOSE To determine the effectiveness of exchange and upsizing of malfunctioning small-caliber double-J (JJ) ureteral stents. MATERIALS AND METHODS Thirty-one patients with malfunctioning cystoscopically placed small-caliber (6 or 7 F) JJ stents underwent transurethral (n = 28) or transrenal (n = 3) exchange and upsizing to a large-caliber (10 F) JJ stent from 2013 to 2022. Ureteral obstruction was malignant in 20 patients (65%) and benign in 11 (35%). Fifteen patients (48%) presented with persistent hydroureteronephrosis and 16 patients (52%) with worsening hydronephrosis. Acute kidney injury (AKI) was present in 19 patients (61%) at the time of stent malfunction. Therapeutic success was defined as resolution of hydronephrosis and AKI, if present. RESULTS JJ stent exchange and upsizing was technically successful in 31 patients (100%) with no immediate adverse events. Therapeutic success was achieved in 27 patients (87%). During follow-up (median, 97 days; IQR, 32-205 days), 2 patients who initially achieved therapeutic success had stent malfunction, requiring conversion to percutaneous nephrostomy drainage (2/27, 7%). CONCLUSIONS Exchange and upsizing to large-caliber JJ stents can relieve urinary obstruction and resolve AKI in patients with malfunctioning small-caliber JJ stents. Large-caliber JJ stents should be considered as a salvage option for patients who wish to continue internal drainage and avoid percutaneous nephrostomy.

Abstract
Objectives The aim is to evaluate the safety and efficacy of retrograde ureteral catheterization under local anesthesia in patients with urinary tract infections complicated by hydronephrosis caused by ureteral stone obstruction. Materials and Methods From October 2020 to September 2021, a retrospective analysis of patients' medical records was performed. Records of past history, physical examination, laboratory tests, and imaging investigations were reviewed. Retrograde ureteric stent (RUS) was performed under local anesthesia using cystoscopes and guided by portable fluoroscopy. Real-time fluoroscopy was used to verify the double-J stent position and confirm a smooth process. The postoperative recovery and length of admission were also recorded. Results A total of 14 patients with ureteral stone obstruction with infective hydronephrosis received 15 total emergency RUS procedures (one bilateral). Intraoperative findings, operation times, and infection signs were recorded and analyzed. All patients met systemic infection criteria, with a mean body temperature of 38.7°C ± 1.7°C. Leukocytosis was noted in 8 (57.1%) patients. Elevated C-reactive protein (8.5 ± 6.3 mg/L) and procalcitonin (24.1 ± 22.0 ng/mL) were found in 13 (92.9%) and 9 (64.3%) patients, respectively. Mean stone size was 8.5 ± 6.3 mm, mostly localized to the upper ureter (upper: 12; middle: 0; lower: 3). Mean operation time was 14.1 ± 4.3 min. After emergency drainage, all patients improved and were discharged after infection was controlled. The average length of admission was 6.2 ± 2.2 days. Conclusion RUS under local anesthesia is safe and effective for treating infective hydronephrosis due to ureteral stone obstruction. A randomized controlled trial with a large sample remains necessary to validate these findings.

Abstract
OBJECTIVE Urinary diversion is the treatment of choice for cervical cancer patients with urinary tract obstruction. The aim of this study is to determine the survival rate among advanced cervical cancer patients with hydronephrosis who undergo urinary diversion and factors that affect patient survival. METHODS Clinical data of cervical cancer patients with International Federation of Gynecology and Obstetrics (FIGO) Stage-IIIB or advanced cervical cancer were not surgical candidates admitted to Saiful Anwar Hospital, Malang from May 2016 to August 2022 were retrospectively analyzed. The parameters including age, cancer stage, comorbidity, cancer treatment at diagnosis, hydronephrosis treatment, grade, site, and survival, were analyzed using the IBM SPSS Statistics version 21. The significance level was set up to 0.05. RESULT One hundred eighteen patients were included in this study. Most patients were under 60 (84.75%) and presented with stage IIIB (79.66%). Diabetes mellitus type 2 (8.47%), hypertension (7.63%), acute kidney injury (16.10%), and chronic kidney disease (36.78%) were comorbidities discovered in patients. More than half of patients received chemotherapy (54.24%). Ureteral stents were inserted in 85.59% of patients. Patients with moderate hydronephrosis were the most common, accounting for 67.80% of all cases. Patients with bilateral hydronephrosis outnumber those with unilateral by 91.53% to 8.47%. The survival rate did not differ significantly between ureteral stents (median survival was 11.00 months) and percutaneous nephrostomies (median survival was 15.00 months), p=0.749. In univariate analysis, age, cancer stage, and hydronephrosis stage were associated with worse 1-year survival. In multivariate analysis, age, DM type 2, cancer staging and hydronephrosis staging were associated with worse 1-year survival. CONCLUSION In advanced cervical cancer patients, urinary diversion techniques such as ureteral stents and percutaneous nephrostomy offer similar survival rates. In addition, age, cancer stage, DM type 2, and hydronephrosis site are strong predictors of a worsening survival rate in patients.

Abstract
OBJECTIVE Ureteral stent replacement is a routine treatment for hydronephrosis in patients with cervical cancer. We developed an improved ureteral stent-change operation for hydronephrosis in cervical cancer patients and compared its outcomes with traditional stent change procedures. STUDY DESIGN Clinical data of hydronephrosis in cervical cancer patients who were admitted to our hospital from August 2014 to October 2019 were analyzed. We retrospectively reviewed 131 cervical cancer patients, out of which 43 cases included patients in the improved operation group, whereas 88 patients with hydronephrosis followed the traditional ureteral stent-change operation for ureteral obstruction. The outcomes of the two procedures were compared using the propensity score matching method. RESULTS As opposed to the traditional ureteral stent change strategy, the patients in the improved group required shorter operation time (p = 0.001) and higher success rate (p = 0.004). The FIGO stage (p = 0.046), the level of ureteral obstruction (p = 0.027), radiotherapy history (p = 0.01), stent replacement times (≤2times or > 2times) (p = 0.001), and serum creatinine level (≤200 μmol/L or > 200 μmol/L) (p < 0.001) were significantly different between the two groups before propensity score matching. Propensity score matching analysis was used to eliminate the clinical differences of 43 patients in the traditional group; however, the span of visual hematuria during the surgical complications was not included (p = 0.026) in the results. CONCLUSION An improved ureteral stent change operation is an advanced treatment option for cervical cancer patients suffering from hydronephrosis. In contrast to traditional ureteral stent change techniques, our developed strategy lowers complications such as visual hematuria but improves the success.

Obstructing Ureteral Calculi and Presumed Infection: Impact of Antimicrobial Duration and Time From Decompression to Stone Treatment in Developing Urosepsis. Urology 2023; 172:55-60. [PMID: 36334770 DOI: 10.1016/j.urology.2022.10.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Revised: 09/13/2022] [Accepted: 10/12/2022] [Indexed: 11/19/2022]
Abstract
OBJECTIVE To determine whether the duration of antibiotic treatment and timing between urgent renal decompression and stone intervention impacts the risk of developing urosepsis following definitive stone treatment. MATERIALS & METHODS A retrospective review of patients who were diagnosed with obstructive urolithiasis and underwent urgent decompression with a ureteral double J stent or percutaneous nephrostomy at our institution between 2012 and 2018 was performed. We narrowed our analysis to the subset of patients who had suspected infection and received definitive stone treatment at our institution. Demographic, infection and antimicrobial data, and initial admission to stone treatment characteristics were collected. Factors associated with developing urosepsis were analyzed. RESULTS We identified 872 patients who were treated with urgent renal decompression, of which 215 were analyzed that had suspected infection and also received definitive stone removal at our institution. Thirty-three had fevers, 64.2% had a positive urine culture, and 45.6% had urosepsis at the initial presentation. The median antibiotics duration post decompression was 13 days (IQR 8-18). The median duration from decompression to stone treatment was 17 days (IQR 12-27). Of all, 4.6% of the patients developed urosepsis post ureteroscopy and 5% post percutaneous nephrolithotomy. No factors were associated with developing urosepsis post stone treatment on logistic regression analyses. CONCLUSION In patients requiring urgent decompression for obstructing urolithiasis and suspected infection, the time between decompression and stone treatment and the length of antibiotic exposure did not impact rates of postoperative urosepsis. This highlights the importance of maintaining high clinical suspicion for prolonged use of antibiotics, to prevent overtreatment and possible exacerbation of antibiotic resistance.

Abstract
Patients receiving palliative care (PC) can present with or develop a host of urological needs or complications. These needs can include attention to sexual health, urinary incontinence, genitourinary bleeding, and urinary tract obstruction by benign, malignant, or urinary stone diseases. These varied conditions require that PC clinicians understand invasive and noninvasive medical, surgical, and radiation options for treatment. This article, written by a team of urologists, geriatricians, and PC specialists, offers information and guidance to PC teams in an accessible "Top Ten Tips" format to increase comfort with and skills around assessment, evaluation, and specialist referral for urological conditions common in the PC setting.

Clinical phenotypes and long-term outcome of kidney involvement in Erdheim-Chester histiocytosis. Kidney Int 2023; 103:177-186. [PMID: 36374823 DOI: 10.1016/j.kint.2022.09.027] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2022] [Revised: 08/10/2022] [Accepted: 09/01/2022] [Indexed: 11/07/2022]
Abstract
Erdheim-Chester disease (ECD) is a rare non-Langerhans cell histiocytosis that frequently infiltrates the peri-kidney space ("hairy kidney" appearance), kidney pelvis and proximal ureters, leading to obstructive uropathy. Here, we analyzed the clinical characteristics, imaging findings and long-term kidney outcome of a large multicenter cohort comprising 195 consecutive patients with ECD. Retroperitoneal peri-kidney or peri-ureteral involvement was detected at diagnosis in 147 patients. Of them, 70 had hydronephrosis (bilateral in 47), and 16 with kidney atrophy (unilateral in 14). Kidney vascular peduncle infiltration was found in 60 patients, and kidney artery stenosis in 31. The estimated glomerular filtration rate (eGFR) at diagnosis was significantly lower in patients with than in those without peri-kidney involvement (median 74 vs. 98 mL/min/1.73 m2). Ureteral stenting often failed to achieve kidney function recovery. A total of 181 patients received medical therapies: first-line treatments included interferon-α (61%), BRAF-inhibitors (17%), mTOR-inhibitors (7%), or other drugs (15%). These therapies were efficacious for ECD but rarely induced kidney function improvement (one-year eGFR increase over 25% in under 10% of patients). After a median of 43 months, 19% of patients died and 5% developed kidney failure. Among patients with peri-kidney involvement, 44% developed chronic kidney disease (CKD) 3-5 at five years vs. 5% of those without. Unadjusted predictors of advanced CKD and kidney failure/death were age over 50 years, hypertension, BRAFV600E mutation, and baseline eGFR. At multivariable analysis, cardiovascular comorbidities were associated with advanced CKD, and age over 50 years with kidney failure/death. Thus, kidney involvement is common in ECD and can lead to CKD or kidney failure despite effective medical therapies or urological procedures.

Abstract
There is a well-known relationship between malignancy and impairment of kidney functions, either in the form of acute kidney injury or chronic kidney disease. In the former, however, bilateral malignant ureteral obstruction is a surgically correctable factor of this complex pathology. It warrants urgent drainage of the kidneys in emergency settings. However, there are multiple controversies and debates about the optimal mode of drainage of the bilaterally obstructed kidneys in these patients. This review addressed most of the concerns and provided a comprehensive presentation of this topic from the recent literature. Also, we provided different perspectives on the management of the bilateral obstructed kidneys due to malignancy. Despite the frequent trials for improving the success rates and functions of ureteral stents, placement of a percutaneous nephrostomy tube remains the most recommended tool of drainage due to bilateral ureteral obstruction, especially in patients with advanced malignancy. However, the disturbance of the quality of life of those patients remains a major unresolved concern. Beside the unfavorable prognostic potential of the underlying malignancy and the various risk stratification models that have been proposed, the response of the kidney to initial drainage can be anticipated and evaluated by multiple renal prognostic factors, including increased urine output, serum creatinine trajectory, and time-to-nadir serum creatinine after drainage.

Abstract
BACKGROUND Percutaneous nephrostomy (PCN) and Double J stenting (DJS) are the 2 main treatment options of ureteral obstruction. We evaluate which of these 2 methods is superior concerning the course of procedure, postoperative complication and quality of life. METHODS A detailed review of electronic databases including PubMed, Embase, Cochrane Library, China Biology Medicine disc, China National Knowledge Infrastructure up to February 21st, 2021 was searched. Continuous data were evaluated using mean difference (MD) with 95% confidence interval (CI), while nominal data were analyzed by risk ratio (RR) with 95% CI. Meanwhile, we performed the subgroup analysis based on study design, disease type, sample size, sepsis, DJ diameter, nephrostomy diameter, anesthesia type and guidance under X-ray or ultrasound. RESULTS There were 18 previous studies included in current study. As a result, we found that there were significant differences in fluoroscopy time (MD = 0.31; 95% CI, 0.14-0.48, P < .001) and hospital stay (MD = 1.23; 95% CI, 0.60-1.85, P < .001). However, no statistic difference was detected in operative time (MD = 5.40; 95% CI, -1.78 to 12.58, P = .140) between the paired groups. Although DJS showed a higher rate of postoperative complications (25.19% vs 17.61%), there was no significant difference in the incidence of complications following DJS and PCN (RR = 0.92; 95% CI, 0.60-1.43; P = .720). Based on the EuroQol analysis, the 2 main treatment options had different impacts on quality of life. The pooled results showed that PCN patients reported more difficulties in self-care compared to DJS patients (RR = 3.07; 95% CI, 1.32-7.14; P = .009). CONCLUSIONS DJS is a safe and better method of temporary urinary diversion than PCN for management of ureteral obstruction with shorter fluoroscopy time and hospital stay. As for quality of life, patients receiving PCN had a distinct difficulty in self-care compared to those receiving DJS. However, these 2 treatment options often depends on the individual situation.

Abstract
Background: To evaluate the efficacy of double percutaneous nephrostomy (PCN) combined with ureter occlusion stent for treating cervical cancer complicated with vesicovaginal fistula (VVF). Materials and Methods: A retrospective analysis was performed for 12 patients with cervical cancer complicated with VVF. Regardless of surgical resection, radiotherapy alone or combined chemoradiotherapy were carried out in all patients. After VVF was diagnosed by gynecological examination, imaging, and cystoscopy, concurrent double PCN and ureter occlusion stent implantation were performed for all patients. Results: All patients successfully received ureter occlusion stent implantation after nephrostomy. The success rate of nephrostomy and stent placement was 100% (12/12). After intervention, urinary fistula immediately disappeared in all patients. One week post-surgery, bilateral hydronephrosis disappeared in 4 patients, and their renal insufficiency and renal function returned to normal. One month after operation, 6 patients with genital eczema or ulcer and 5 patients with urinary tract infection were cured. During follow-up, there were no recurrence in urinary fistula, renal dysfunction, and other complications. Conclusion: Double PCN combined with ureter occlusion stent could effectively treat cervical cancer complicated with VVF hydronephrosis, urinary tract infection, and renal insufficiency and contribute to alleviate all kinds of clinical discomfort.

Abstract
Objective To determine the impact of preoperative stent placement on postradiotherapy stricture rate in patients with cervical cancer after radical resection. Methods This study was a retrospective analysis of data collected from 55 cervical cancer patients treated with radiotherapy between June 2016 and June 2020. Patients were divided into the stent and control groups. After 3 months, the stricture rate and the complications related to stent placement between the two groups were compared. Results There were 12 (46.2%) and 10 (34.5%) cases of ureteral stricture in the stent (n = 26) and control (n = 29) groups, respectively, three months after the end of radiotherapy. The incidence rates of ureter stricture in the two groups were not significantly different (P = 0.378). Moreover, there were 20 units (38.5%) and 15 units (25.9%) ureteral strictures in the stent and control groups, respectively. No significant difference in the incidence rates of ureteral strictures was found between the two groups (P = 0.157). There were 13 (50.0%) and 10 (34.5%) cases of ureteral stricture in the stent (n = 26) and control (n = 29) groups, respectively, six months after the end of the radiotherapy. The incidence rates of ureter stricture in the two groups were not significantly different (P = 0.244). Moreover, there were 21 units (40.4%) and 15 units (25.9%) ureteral strictures in the stent and control groups, respectively. No significant difference in the incidence rates of ureteral strictures was found between the two groups (P = 0.105). Complications related to stent placement such as urinary tract infections and bladder irritation were statistically significant (P = 0.006 and P = 0.036) between the two groups; while the other complications were not significantly different (P = 0.070, P = 0.092 and P = 0.586). Conclusions Ureteral stents may not reduce the incidence of ureteral stricture after radiotherapy in patients with cervical cancer. The stent needs to be replaced regularly, and the complications related to stent placement may occur at any time. Thus, preoperative stent placement should be cautious for the clinical management of cervical cancer patients treated with postoperative radiotherapy.

Abstract
Abstract
Background Cervical cancer is the fourth most common cancer among women globally. Age-standardized cervical cancer mortality is higher in East Africa than anywhere else in the world. Prior to October 2018, patients presenting with obstructive uropathy secondary to late-stage cervical cancer in Tanzania who were no longer eligible for palliative chemoradiation therapy were discharged home without intervention. The purpose of this study was to evaluate whether the establishment of a percutaneous nephrostomy service in a quaternary hospital in Dar es Salaam, Tanzania, a resource-limited country, benefits patients who have late-stage cancer induced obstructive uropathy.
Materials and Methods A retrospective study was performed on patients who presented with obstructive uropathy secondary to late-stage cervical cancer and have undergone percutaneous nephrostomy at Muhimbili National Hospital and Ocean Road Cancer Institute from October 2018 to May 2021. Twenty-one interventional radiology (IR) teaching teams consisting of IR attendings, IR technologists, and nurses travelled to Tanzania from North America on monthly 2-week trips during that period. A review of preprocedural, procedural, and follow-up data was performed using Research Electronic Data Capture. Statistical analysis and comparison were performed on patients' creatinine levels preprocedure, 7 days and 30 days postprocedure.
Results Sixty-two patients qualified to be included in this study. In addition to the initial 62 nephrostomy placements, 14 follow-up procedures were performed either under visiting faculty supervision or independently by the Tanzanian IR fellows. Technical success rate was 98.7%. Complications (SIR Class A and B) occurred in eight cases. The average preprocedure creatinine (1051.48 ± 704.08µmol/L) decreased by 59% 7 days postprocedure and by 77% 30 days postintervention. Postprocedural clinical information was obtained for 28 (45.2%) patients and 18 were able to restart chemotherapy following nephrostomy.
Conclusion Prior to 2018, percutaneous nephrostomy placement was not available in Tanzania. This study presented the initial safety, technical feasibility, and clinical benefit of establishing a percutaneous nephrostomy service in such a resource-limited setting.

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
This case study examines a patient with severe hydronephrosis caused by ureteral obstruction, secondary to ovarian serous carcinoma. Gynecologic malignancies, especially advanced ovarian carcinoma, are common extrinsic causes of obstructive hydronephrosis. Sonography is a valuable modality to visualize the kidneys, diagnose hydronephrosis, and determine the grade of hydronephrosis. The treatment of hydronephrosis aims to remove the build-up of urine, prevent permanent kidney damage, and treat the underlying cause. Prolonged or severe cases of hydronephrosis can lead to acute kidney injury.

Abstract
A 55-year-old male with a past medical history of type 2 diabetes mellitus on metformin presented to the emergency department (ED) due to shortness of breath and three days of lumbar back pain. Workup revealed bilateral obstructing ureteral stones causing bilateral hydronephrosis, acute kidney injury (AKI), and profound anion gap metabolic acidosis due to concomitant metformin-associated lactic acidosis (MALA). In the ED, the patient developed profound shock refractory to fluid resuscitation, requiring initiation of multiple vasopressors, and stress dose steroids. He was transferred to the interventional radiology suite for bilateral percutaneous nephrostomy tubes and only improved once continuous renal replacement therapy was initiated.

Management of Nephrolithiasis in Pregnancy: Multi-Disciplinary Guidelines From an Academic Medical Center. Front Surg 2021; 8:796876. [PMID: 35028309 PMCID: PMC8751485 DOI: 10.3389/fsurg.2021.796876] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2021] [Accepted: 12/02/2021] [Indexed: 11/13/2022] Open
Abstract
Introduction: The management of nephrolithiasis during pregnancy can be stressful for urologists due to concerns for investigations and treatments that may pose risk of fetal harm, and unfamiliarity with optimal management of these complex patients. In response, we created multi-disciplinary evidence-based guidelines to standardize the care for obstetric patients presenting with flank pain and suspicion for nephrolithiasis. Methods: A multi-disciplinary team involving Urology, Obstetric Anesthesiology, Obstetrics and Gynecology, Diagnostic Radiology, and Interventional Radiology from a single academic medical center was assembled. A PubMed search was performed using keywords of pregnancy/antepartum, nephrolithiasis/calculi/kidney stones, ureteroscopy, non-obstetric surgery, complications, preterm delivery, MRI, computerized tomography, renal bladder ultrasound (RBUS), and anesthesia to identify relevant articles. Team members reviewed their respective areas to create a comprehensive set of guidelines. One invited external expert reviewed the guidelines for validation purposes. Results: A total of 54 articles were reviewed for evidence synthesis. Four guideline statements were constructed to guide diagnosis and imaging, and seven statements to guide intervention. Guidelines were then used to create a diagnostic and intervention flowchart for ease of use. In summary, RBUS should be the initial diagnostic study. If diagnostic uncertainty still exists, a non-contrast CT scan should be obtained. For obstetric patients presenting with a septic obstructing stone, urgent decompression should be achieved. We recommend ureteral stent placement as the preferred intervention if local factors allow. Conclusions: We present a standardized care pathway for the management of nephrolithiasis during pregnancy. Our aim is to standardize and simplify the clinical management of these complex scenarios for urologists.

Abstract
Double-J stent (DJ) placement is usually the treatment of choice for relieving external compression of the ureter. However, in some cases DJ function may become impaired and a percutaneous nephrostomy (PCN) may be required. Previous studies have reported different predictive factors for choosing PCN or DJ insertion as the initial treatment. In this study, we analyzed the risk factors for DJ failure in patients with external ureteral compression. Our results showed that the patients with moderate and severe hydronephrosis (p-value = 0.0171 and 0.0249, respectively), preexisting pyuria (p-value = 0.0128), or lower ureter obstruction (p-value = 0.0305) were more prone to DJ laterality. Age was also an important predictor. Urologists should pay more attention to these patients and consider PCN as the initial treatment.

Abstract
Kidney stone disease (KSD) is a commonly encountered ailment in urologic practice. Urinary tract infection (UTI) is commonly associated with KSD, both as an etiology (e.g., struvite and carbonate apatite stones), and as a complication (i.e., obstructive pyelonephritis and post-operative UTI). Indeed, a significant portion of the economic burden of KSD is skewed toward stones associated with infection. UTI is the most common post-operative complication related to stone intervention with progression to urosepsis as a rare but serious consequence. Risk for infection is influenced by a variety of factors including co-morbid conditions, anatomic abnormalities, prior surgical procedures, and local anti-microbial susceptibility. Understanding these risks and the proper steps to mitigate them is an essential component in reducing post-operative morbidity and mortality. Retrograde intrarenal surgery is routinely used for the treatment of KSD. The objective of this review article is to examine the current literature and guidelines for the prevention and management of stone-related infectious complications associated with retrograde intrarenal surgery. Special attention will be given to the incidence, etiology, and antibiotic prophylaxis choice in the management of stone-related infections. Intraoperative risk mitigation techniques will be discussed in conjunction with the management of post-operative infections. Antibiotic stewardship and the potential benefits of reduced empiric antibiotic treatment will also be discussed.

Predictors of antegrade ureteral stenting failure: a single-center experience in patients with malignant and benign ureteral obstruction. Abdom Radiol (NY) 2021; 46:2188-2194. [PMID: 33226456 DOI: 10.1007/s00261-020-02858-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2020] [Revised: 07/09/2020] [Accepted: 11/05/2020] [Indexed: 10/22/2022]
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
Acute obstructive uropathy is associated with significant morbidity among patients with any condition that leads to urinary tract obstruction. Immediate urinary diversion is necessary to prevent further damage to the kidneys. In many centres, the two main treatment options include percutaneous nephrostomy (PCN) and retrograde ureteral stenting (RUS). The purpose of this study if to compare the efficacy and safety of PCN and RUS for the treatment of acute obstructive uropathy. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, CINAHL, EMBASE, the World Health Organisation International Clinical Trials Registry Platform and ClinicalTrials.gov. We also searched the reference lists of included studies to identify any additional trials. We included randomised controlled trials and controlled clinical trials comparing the outcomes of clinical improvement (septic parameters), hospitalisation duration, quality of life, urinary-related symptoms, failure rates, post-procedural pain [measured using a visual analogue scale (VAS)] and analgesics use. We conducted statistical analyses using random effects models and expressed the results as risk ratio (RR) and risk difference (RD) for dichotomous outcomes and mean difference (MD) for continuous outcomes, with 95% confidence intervals (CIs). Seven trials were identified that included 667 patients. Meta-analysis of the data revealed no difference in the two methods in improvement of septic parameters, quality of life, failure rates, post-procedural pain (VAS), or analgesics use. Patients receiving PCN had lower rates of haematuria and dysuria post-operatively and longer hospitalisation duration than those receiving RUS. PCN and RUS are effective for the decompression of an obstructed urinary system, with no significant difference in most outcomes. However, PCN is preferable to RUS because of its reduced impact on the patient's post-operative quality of life due to haematuria and dysuria, although it is associated with slightly longer hospitalisation duration.

Abstract
Emergence of malignant ureteral obstruction (MUO) has been reported as a sign of poor prognosis; however, the distribution of survival time in patients with MUO is considerably wide, and no risk classification score has been constructed. To evaluate whether a novel risk classification score for overall survival that we previously developed, is effective in a large cohort. Investigator-initiated, prospective, multicenter diagnostic/prognostic study was conducted. Patients with MUO were divided into three risk groups based on the score calculated using four prognostic factors (PLaCT: Primary site, Laterality, serum Creatinine level, and Treatment for primary site) at the first visit, and prospective follow-up was performed. Overall survival and ureteral stent failure-free survival of each risk group were compared. In total, 300 patients with 21 different primary sites were enrolled. The numbers of patients in good, intermediate, and poor risk groups were 105, 106, and 89, respectively. Median survival times of patients in good, intermediate, and poor risk groups were 406, 221, and 77 days, respectively (P < 0.0001). In 217 patients with ureteral stenting, median ureteral stent failure-free survival times of good, intermediate, and poor risk groups were 385, 183, and 57 days, respectively (P < 0.0001). Limitations include the limited ethnicity and the extended duration of study enrollment. The novel PLaCT risk classification score could divide MUO patients into three risk groups with distinct survival times and ureteral stent patencies. This score will aid in establishing prognosis and treatment strategy for all physicians engaged in cancer treatment.

Abstract
Retroperitoneal tumors can cause ureteric obstruction leading to obstructive uropathy. Early preoperative ureteric stenting helps to improve renal function and also helps in identifying ureters and prevent ureteric injury during surgery. This study was aimed at assessing the outcome of preoperative stenting in optimizing such patients. A total of 24 cases were enrolled. Of these, 15 patients who had obstructive uropathy were taken for ureteric stenting preoperatively and other 9 patients have undergone surgery without stenting. Twelve patients were stented successfully but 3 patients could not be stented (underwent percutaneous nephrostomy). All 24 patients underwent laparotomy, and of the 12 stented patients, 11 underwent successful resection and one had unresectable tumor. The patient's serum creatinine was assessed initially and then twice after stenting (48 h and 5 days). Serum creatinine was also estimated 24 h after excision of the tumor. In the successfully stented and operated patients, mean initial creatinine was 7.85. The mean creatinine at 48 h and 5 days after stenting was 4.29 and 1.19 respectively. The mean creatinine 24 h after resection of the tumor was 1.04. Of the non-stented patients, 3 had ureteric injury during surgery. We conclude that preoperative ureteric stenting is helpful for optimization of patients with retroperitoneal tumors with obstructive uropathy.

Abstract
BACKGROUND: Despite recent advances in the management of muscle-invasive bladder cancer (MIBC), treatment outcomes remain suboptimal, and variability exists across current practice patterns. OBJECTIVE: To promote standardization of care for MIBC in Canada by developing a consensus guidelines using a multidisciplinary, evidence-based, patient-centered approach who specialize in bladder cancer. METHODS: A comprehensive literature search of PubMed, Medline, and Embase was performed; and most recent guidelines from national and international organizations were reviewed. Recommendations were made based on best available evidence, and strength of recommendations were graded based on quality of the evidence. RESULTS: Overall, 17 recommendations were made covering a broad range of topics including pathology review, staging investigations, systemic therapy, local definitive therapy and surveillance. Of these, 10 (59% ) were level 1 or 2, 7 (41% ) were level 3 or 4 recommendations. There were 2 recommendations which did not reach full consensus, and were based on majority opinion. This guideline also provides guidance for the management of cisplatin-ineligible patients, variant histologies, and bladder-sparing trimodality therapy. Potential biomarkers, ongoing clinical trials, and future directions are highlighted. CONCLUSIONS: This guideline embodies the collaborative expertise from all disciplines involved, and provides guidance to further optimize and standardize the management of MIBC.

Abstract
Objective To analyze the results obtained with a modified antegrade double J catheter insertion (JJ stenting) technique in patients with urinary tract obstruction due to malignancy. Materials and Methods This was a retrospective analysis of data collected from patients undergoing antegrade JJ stenting for malignant ureteral obstruction in the interventional radiology department of our institution between March 1, 2017 and May 31, 2019. Results Antegrade JJ stenting was performed in 32 patients (20 women and 12 men). The mean age was 66.2 years among the females and 61.5 years among the males. A total of 53 antegrade JJ stenting procedures were performed. The procedure was successful in 50 cases and failed in 3 (due to migration of the double J catheter in 2 and due to technical failure in 1). Complications occurred in 3 patients (low back pain, in 1, subcapsular hematoma, in 1, and pyelonephritis, in 1). The procedure time ranged from 14 min to 55 min. Conclusion In patients with ureteral obstruction due to malignancy, antegrade JJ stenting is safe and effective. The technique selected in our study is easily reproduced and can be performed by a trained professional.

Abstract
Objective To compare two percutaneous techniques used in the treatment of malignant obstructive uropathy-antegrade double-J stent placement (JJ stenting) and percutaneous nephrostomy-in terms of their cost-effectiveness, from the perspective of the Brazilian public health care system. Materials and Methods In this cost-effectiveness analysis, we employed decision-analytic modeling. We calculated material costs from 2017 factory prices listed by the Brazilian Pharmaceutical Market Regulatory Board (for medications) and published in the journal Revista Simpro (for medical devices). Procedure-related costs were evaluated, as were the rates of technical and clinical success. Those measures were then used as inputs for a cost-effectiveness analysis comparing the two procedures. Results The sample comprised 41 patients, of whom 16 underwent antegrade JJ stenting (26 procedures) and 10 underwent percutaneous nephrostomy (15 procedures). Patient records, radiology reports, and expense reports of the interventional radiology department of the public hospital where the study was conducted were analyzed retrospectively. There were no significant complications: one patient had low back pain, and one had a transient retroperitoneal hematoma. The mean procedure time was 24 min, and clinical success (improvement in serum creatinine and resolution of hydronephrosis) was achieved in 97.5% of the cases. The average cost of JJ stenting was significantly lower than was that of percutaneous nephrostomy (US$164.10 vs. US$552.20). Conclusion In the absence of any clinical contraindications, antegrade JJ stenting is a suitable alternative to both percutaneous nephrostomy and retrograde stenting in patients with dilated renal collecting systems secondary to malignant ureteral obstruction, providing significant cost savings and high success rates.

Abstract
Objective: to evaluate the impact on the quality of life as well as anxiety and pain in patients with nephrostomy tubes. Method: this is a longitudinal descriptive study performed on a sample of n=150 patients. To evaluate the quality of life, the EuroQol-5D questionnaire was used; anxiety was quantified by the Beck Anxiety Inventory; to study pain, a visual analogue scale was employed. Results: statistically significant differences were found in the quality of life, with its worsening (r = 0.51; p <0.01) when evaluated at the first tube replacement. Patients presented mild to moderate anxiety before the procedure, which was reduced at the first tube replacement, although this difference was not significant (r = 0.028, p = 0.393). Finally, the degree of pain was also significantly reduced (r = 0.13, p<0.01) after six weeks. As for gender, women presented the worst values in the three variables studied (worse quality of life and greater anxiety and pain). Conclusions: nephrostomy tubes have a negative impact on the patient’s quality of life. During the time they live with these tubes, patients have mild to moderate pain and anxiety.

Abstract
AIM To determine whether antegrade or retrograde methods should be preferred for double-J stent placement in patients with malignant ureteral obstruction (MUO). MATERIAL AND METHODS The medical records of patients treated for MUO in the Urology and Interventional Radiology Clinic, Konya Training and Research Hospital, were reviewed retrospectively. Patients with benign aetiology were excluded from the study. Reports of the procedures, ultrasonography findings, computed tomography (CT), angiography, and pyelography images and the follow-up records of patients with MUO were assessed. A total of 111 patients and 114 ureteral stenting treatments were included in the study; 63 (55.3%) were operated on using the antegrade ureteral stenting (AUS) method, whereas 51 (44.7%) were operated on using the retrograde ureteral stenting (RUS), method, and the characteristics of these groups were evaluated. The presence of hydroureteronephrosis and ureteral tortuosity were determined. RESULTS Overall success rates were found to be 95.2% using the AUS method and 47.1% using the RUS method. The technical success of the antegrade method was significantly higher in patients with or without tortuosity (respectively: p=0.005, Z shape p=0.001, pigtail shape p=0.035″). The technical success of the antegrade method was significantly higher in patients with hydroureteronephrosis (p=0.001). CONCLUSION The AUS technique should be the first choice for double-J stent placement in patients with MUO.

Abstract
Urinothorax is the presence of the urine in the pleural space. This condition is very rare and occurs due to unrelieved obstruction of urinary flow. A 20-year-old female presented 7 days after cesarean section with tachypnea, and generalized abdominal pain. There was absent air entry over the left hemithorax. CT scan showed massive left pleural effusion and a stone obstructing the renal pelvis with hydronephrosis and peri-renal collection. The pleural fluid had high fluid creatinine level suggesting urine collection. Ureteroscopy done and double J catheter inserted. The effusion became loculated, thoracotomy and pleural decortication done.

Abstract
Purpose To compare patients with sepsis due to obstructive urolithiasis (Sep-OU) and underwent drainage by percutaneous nephrostomy (PCN) or a double-J (DJ)-ureteral stent and to identify predictive risk factors of DJ stent failure in these patients. Materials and Methods We reviewed our records from January 2013 to July 2018 and identified 286 adult patients with Sep-OU out of which 36 had bilateral involvement, thus total 322 renal units were studied. Urologic residents in training carried out both ureteral stenting and PCN tube placement. Demographic data and stone characteristics were recorded along with Charlson comorbidity index. For predicting risk factors of DJ stent failure, those variables that had a p-value <0.1 in univariate analysis were combined in a multinomial regression analysis model. Results The patients with PCN placement were significantly older than those with DJ stent placement (p=0.001) and also had significant number of units with multiple calculi (p=0.018). PCN was also placed more frequently in those patients with a upper ureteric calculi (p<0.05). On multinomial regression analysis multiple calculi (p=0.014; odds ratio [OR], 4.878; 95% confidence interval [CI], 1.377–17.276) and larger calculi size (p=0.040; OR, 0.974; 95% CI, 0.950–0.999) were the significant predictors of DJ stent failure. Conclusions In patients with sepsis from obstructive urolithiasis due to larger and multiple calculi a PCN placement might be better suited although this data requires further prospective randomized studies to be extrapolated.

Abstract
BACKGROUND This study investigated the clinical outcomes of stent placement for malignant extrinsic ureteral obstruction (MUO) and predictive factors for stent failure. METHODS We retrospectively analyzed clinical data for 91 patients with radiologically significant hydronephrosis due to MUO who underwent successful stent placement. In total, 132 ureters were stented for the decompression. Factors related to stent failure were analyzed with a Cox proportional hazards model. RESULTS Stent failure occurred in 25 ureters in 20 patients. The median interval to failure was 63 days. The multivariate analysis showed that the significant predictors of stent failure were bladder invasion and severe hydronephrosis before the stent insertion. The patients were divided into three groups based on these two factors: low-risk (neither factor; 85 patients), intermediate-risk (one factor; 37), and high-risk (both factors; 10). The median stent failure-free survival rate at 3 months was 94.8% in the low-risk, 71.8% in the intermediate-risk and 55.6% in the high-risk group, respectively. Of the ureters with stent failure, there was successful re-replacement of internal stents in 3 low-risk, 6 intermediate-risk and no high-risk ureters. Replacement by nephrostomy was done in 2 low-risk, 5 intermediate-risk and 7 high-risk ureters. CONCLUSION The patients considered at low-risk could be managed without stent failure by internal stenting. However, the patients at high-risk may require the consideration of nephrostomy or other alternatives as the initial treatment. Our stratification model may allow better risk stratification for patients with regard to ureteral stenting, helping to identify patients for whom ureteral stenting is indicated.

Abstract
Introduction The absence of guidelines in the management of extramural malignant ureteric obstruction leads to confusion in decision making and in the interaction between urology and other clinical disciplines. In this study, we surveyed consultant urologists with the goal of achieving a better consensus on optimal management options. Methods A multiple choice survey was sent via the online survey tool "SurveyMonkey" to all consultant urologists practicing in the Republic of Ireland. Results There was a response rate of 57.5% (n = 23). Twenty-two (96%) consultants consider the use of percutaneous nephrostomy with placement of antegrade ureteric stent but only 22% (n = 5) would consider using a metallic stent. Eleven (48%) respondents favor retrograde stenting in the first instance with an equal proportion choosing an antegrade method. Nine (39%) consultants perform the initial stent change at 4-6 months, 8 (35%) at 2-4 months, and 1 at < 2 months and 6-10 months respectively. Total 59% (n = 13) of respondents felt that the duration of expected patient survival influenced their decision and agreement to stent with 42% (n = 8) saying this survival would need to be > 6 months and 82% (n = 18) were generally happy with the level of ongoing communication between urology and the primary service managing the patient. Conclusion There is a lack of consensus regarding the management of this challenging problem, particularly with regard to timing of first stent change and whether to initially use an antegrade or retrograde approach. This reflects the heterogeneous patient cohort and the important factors of life expectancy and patient co-morbidities.

Abstract
PURPOSE The goal of this study was to determine the efficacy and safety of tandem ureteral stent placement in the management of malignant ureteral obstruction (MUO) refractory to single ureteral double-J stent drainage in women with gynecological malignancies. MATERIALS AND METHODS A retrospective study was performed on 14 women (mean age, 54.5±9.6 [SD] years; range: 38-70 years) who had tandem stent placement following failed single ureteral double-J stent placement from 2012 to 2017. Survival analyses were performed with Kaplan-Meier method. RESULTS Twenty-nine successful procedures were performed on 19 ureters (19 primary stent placement and 9 exchange procedures). Technical success of primary tandem stent placement was 95% (19/20 procedures). Mean follow-up was 180.1±173.7 (SD) days (range: 62-616 days). Median estimated survival of the patients was 118 days (Q1: 261, Q3: 95; range: 62-616 days). Primary stent failure rate was 25% and assisted stent failure rate was 21.4%. There was no significant difference among survival of patients with and without tandem stent failure. Mean estimated primary stent patency and assisted stent patency were 171.4±13.8 (SD) days and 409.9±59.8 (SD) days, respectively. Four patients underwent 1 to 3 stent exchanges. Median exchange time was 181 days (Q1: 151, Q3: 191, range: 141-214 days) and technical success rate was 100%. Grade 2 and 3 complication rates were 25% and 3.6%, respectively. CONCLUSION Tandem ureteral stent placement is a feasible, safe and effective procedure for the management of failed ureteral double-J stent placement in women with gynecological malignancies.

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
Ureteric stenting is an effective drainage method in patients with acute urinary tract infection caused by ureteral calculi; however, the optimal ureteral stent indwelling time has not been clearly defined. The aim of this study was to evaluate the effect of ureteric stent indwelling time on the treatment of acute infection secondary to urinary tract calculi. A total of 142 patients with acute infection caused by urinary tract calculi were identified retrospectively from January 2011 to August 2015 at our institution. 63 patients were with ureteric stenting for 7 days (A group) and 79 patients with ureteric stenting for more than 7 days (B group). The patient characteristics of two groups were analyzed and the clinical data before and after stenting were compared. The postoperative complication outcomes were collected and analyzed. Effective drainage obtained from ureteral stenting clearly abated the infection after stenting for 7 days; WBC count, WBCs in urine, and positive rate of urine culture were significantly decreased compared with the condition of immediate stenting. Both groups showed similar stone clearance rates (96.8% vs. 96.2%, p = 0.841), and there was no significant difference in the rate of postoperative complications, especially related to urinary tract infection (6.3% vs. 6.3%, p = 1.000). It is safe and effective for patients with acute urinary tract infection secondary to urinary tract calculi to be treated by ureteroscopic lithotripsy after stenting for one week. Prolonging the stenting period achieves no added benefit for patients.

Abstract
Ureteral obstruction represents a heterogeneous disease pattern and is treated by ureteral stenting or percutaneous nephrostomy (PCN) depending on the necessity. The benefits of urinary diversion with ureteral stenting or PCN in malignant ureteral obstruction (MUO) for patient survival are only moderate. No differences have been found between ureteral stenting and PCN in MUO with regard to median patient survival and complication rates. In cases of MUO there is currently no evidence that urinary diversion improves the quality of life. Alternative concepts of ureteral stenting, such as tandem ureteral stents, metallic ureteral stents or metal mesh ureteral stents have not yet shown clear benefits. In benign ureteral obstruction, prospective randomized studies have demonstrated comparable quality of life after PCN or ureteral stenting. The method of choice for urinary diversion is influenced by the recommendations, personal experience of the clinician and the availability of the method.
