Cooled radiofrequency ablation versus cryoneurolysis of the genicular nerves for the symptomatic pain management in knee osteoarthritis: a study protocol of a prospective, randomized, single-blinded clinical trial. J Orthop Surg Res 2023; 18:295. [PMID: 37041607 PMCID: PMC10091842 DOI: 10.1186/s13018-023-03737-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2023] [Accepted: 03/21/2023] [Indexed: 04/13/2023] Open
Abstract
BACKGROUND Cooled radiofrequency ablation (CRFA) and cryoneurolysis (CRYO) are two novel methods of genicular neurolysis to relief pain in symptomatic knee osteoarthritis (KOA). In this study, the two methods will be compared, giving us the opportunity to investigate their efficacy, safety and complications. METHODS In this prospective randomized trial 70 patients with KOA will be recruited using a diagnostic block of four genicular nerves. Two groups will be created through software randomization: a CRFA group (35 patients) and a CRYO group (35 patients). The target of the interventions will be four genicular nerves; the superior medial, superior lateral, inferior medial, as well as the medial (retinacular) genicular branch from vastus intermedius. The primary outcome of this clinical trial will be the efficacy of CRFA or CRYO at 2-, 4-, 12-and 24-weeks post-intervention using the Numerical Rating Pain Scale (NRPS). The secondary outcomes are the safety of the two techniques, as well as the clinical evaluation using the Knee Injury and Osteoarthritis Outcome Score (KOOS), the Oxford Knee Score (OKS), and the 7-point scale of Patient Global Impression of Change (PGIC). DISCUSSION These two novel techniques can block pain transmission through genicular nerves in different ways. In contrast to cryoneurolysis, the CRFA method has been well documented in the past. This is the first clinical trial to compare CRFA vs CRYO and draw conclusions about their safety and efficacy. TRIAL REGISTRATION ISRCTN87455770 [ https://doi.org/10.1186/ISRCTN87455770 ].

Abstract
INTRODUCTION AND AIM Post-inflammatory polyps (PIPs) are considered as indicators of previous episodes of severe inflammation and mucosal ulceration. Inflammatory bowel disease (IBD), namely Crohn's disease (CD) and ulcerative colitis (UC), exhibit a perpetuating, relapsing, and remitting pattern and PIPs is a frequent sequela of chronicity. The aim of this study was to determine whether a high PIPs burden is associated with a more severe disease course in patients with IBD. METHODS This was a multinational, multicentre, retrospective study. IBD patients previously diagnosed with PIPs were retrieved from the endoscopic database of each centre. PIPs burden was evaluated and associated with demographic and clinical data as well as factors indicating a more unfavorable disease course. RESULTS A total of 504 IBD patients with PIPs were recruited (male: 61.9%). The mean age at IBD diagnosis was 36.9 (±16.8) years. Most patients (74.8%) were diagnosed with UC. A high PIPs burden was present in 53.4% of patients. On multivariable Cox regression analysis, high PIPs burden was independently associated with treatment escalation (HR 1.35, 95% CI 1.04-1.75; P=0.024), hospitalization (HR 1.90; 95% CI 1.24 - 2.90; P=0.003), need for surgery (HR 2.28; 95% CI 1.17-4.44, P=0.02) and younger age at diagnosis (HR 0.99, 95% CI 0.98-0,99; p=0.003). CONCLUSION PIPs burden was associated with a more severe outcome. Future prospective studies should focus on the characterisation of PIPs burden as to further risk stratify this patient cohort.

Abstract
Abstract
Background/Introduction
Abbreviation of duration of dual antiplatelet therapy (DAPT) (one or three months) has been recently proposed, especially for high-bleeding risk patients, after percutaneous coronary intervention (PCI) with drug-eluting stent (DES).
Purpose
The purpose of the specific systematic review and meta-analysis was to compare 30-days versus longer duration (≥3 months) of DAPT in patients undergoing PCI with DES, focusing on ischemic and bleeding events.
Methods
Three databases were screened for eligible randomized-control trials. The primary endpoint was the incidence of net adverse clinical events (NACE), as they were defined in each trial. Secondary endpoints consisted of major adverse cardiovascular events (MACE), all-cause and cardiovascular mortality, myocardial infraction, stroke, stent-thrombosis, repeat revascularization and major bleeding.
Results
We included 4 RCTs with a total of 26,576 patients; 13,282 patients were grouped in 30-days DAPT, while the remaining 13,294 were allocated in longer period of DAPT. One-month of DAPT did not significantly reduce NACE (odds ratio [OR]: 0.87, 95% confidence intervals [Cl]: 0.74–1.03); however major bleedings were significantly reduced by 22% (OR: 0.78, 95% Cl: 0.65–0.94). Mortality or ischemic events (stroke, myocardial infraction, revascularization and stent thrombosis) were not affected.
Conclusions
Thirty-days DAPT did not significantly affect NACEs. However, odds of major bleedings were reduced significantly by 22%. Mortality and ischemic events did not differ between the two arms. Thus, 30-days DAPT could be considered as a safe and feasible after PCI with DES in selected patients, especially those in high-bleeding risk. Forthcoming RCTs could shed light on the optimal duration of DAPT.

Abstract
IntroductionUlcerative colitis and Crohn's disease is characterized from a complicated therapeutic management, with bodily and psychological impact to the family.ObjectivesThis study examined the coping strategies among families with a child or adolescent with IBD.AimThe aim was to investigate possible sex differences with respect to coping strategies of the parents would correlated to overall coping strategies.MethodThe participants were biological parents of patients diagnosed with IBD. The total sample included 61 parents with a mean age 46.2 (SD = 7.4). The parents completed:– the Family Crisis Oriented Personal Scales;– the Other As Shamer Scale;– the Experiences of Shame Scale (ESS);– questionnaire concerning socio-demographic information.ResultsMother reported higher levels of social support, accept help, passive appraisal, and overall strategies compared to fathers. The strongest difference was found in accept help (P < 0.001). The feelings of shame of the mothers and fathers of the IBD families were very similar, without statistically significant differences between the groups. The results of the MLR, after controlling for adolescents age, sex and illness duration, revealed that the older age, being a mother, being married and being employment had direct positive associations with the overall coping strategies, while ESS had direct negative associations with the overall coping strategies. The model with all seven predictors explained 68% of the total variance (R2 = 0.68, F = 6.409, P < 0.001).ConclusionsOur findings provide more detailed information on the coping strategies of Greek families with a child or adolescence with IBD.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Intra-Vascular Ultra-Sound (IVUS) and Frequency Domain-Optical Coherence Tomography (FD-OCT), in vivo, intra-vascular, imaging modalities, widely used in the field of coronary disease, have been recently implemented in peripheral endovascular procedures, for procedural assessment, plaque characterization and determination of predictors of treatment outcomes. Their unique characteristics have also been used in order to provide additional features and improve the performance of re-entry devices and atherotomes. Areas covered: Present review focuses on available literature regarding these two promising imaging technologies in the peripheral vasculature, highlighting the added value produced by their use in endovascular therapy, their limitations and their utilization in new endovascular devices. Authors also provide their future perspective and the possible benefits in understanding vascular behavior and lesion characterization in peripheral endovascular interventions. Expert commentary: By providing both quantitative but also qualitative data on vessel and lesion morphology, intravascular imaging modalities offer a valid solution for endovascular treatment evaluation and outcome presentation homogeneity.

Abstract
BACKGROUND Both infrapopliteal (IP) bypass surgery and percutaneous transluminal angioplasty have been shown to be effective in patients with critical limb ischaemia (CLI). The most appropriate method of revascularization has yet to be established, as no randomized trials have been reported. The aim of this study was to compare the outcomes of patients with similar characteristics treated using either revascularization method. METHODS Consecutive patients undergoing IP bypass and IP angioplasty for CLI (Rutherford 4-6) at a single institution were compared following propensity score matching. The study endpoints were primary, assisted primary and secondary patency, and amputation-free survival at 12 months, calculated by Kaplan-Meier analysis. RESULTS Some 279 limbs in 243 patients were included in the study. The two groups differed significantly with respect to the incidence of diabetes (P = 0·024), estimated glomerular filtration rate (P = 0·006), total lesion length (P < 0·001) and Rutherford classification (P = 0·008). These factors were used to construct the propensity score model, which yielded a matched cohort of 125 legs in each group. Primary patency (54·4 versus 51·4 per cent; P = 0·014), assisted primary patency (77·5 versus 62·7 per cent; P = 0·003), secondary patency (84·4 versus 65·8 per cent; P < 0·001) and amputation-free survival (78·7 versus 74·1 per cent; P = 0·043) were significantly better after bypass than angioplasty. However, limb salvage was similar (90·4 versus 94·2 per cent; P = 0·161), and overall complications (36·0 versus 21·6 per cent; P = 0·041) as well as length of hospital stay (18(4-134) versus 5(0-110); P = 0·001) were worse in the surgical bypass group. CONCLUSION There was no difference in limb salvage rates, but patency and amputation-free survival rates were better 1 year after bypass surgery.

Abstract
INTRODUCTION Atherosclerotic plaque analysis using computed tomography angiography (CTA) has been found to be accurate and reproducible in the coronary and carotid arteries. The aim of our study was to assess the utility of this technique in predicting outcome following lower limb endovascular interventions. METHODS Pre-procedural CTA was retrospectively analysed in 50 patients who had undergone femoropopliteal (F-P) angioplasty (and/or stenting). Plaque analysis was performed using TeraRecon workstation by two observers blinded to the long-term outcome. Using the Hounsfield units (HU) scale atherosclerotic plaque composition was subdivided into volumes of soft (-100-100 HU) fibrocalcific (101-300 HU) or calcified (300-1000 HU) components. The relationship between plaque composition, clinical and procedural variables, and the study end points (vessel patency, binary restenosis rate, and Amputation-Free Survival [AFS]) were assessed using multivariate analysis. RESULTS The technical success rate of the endovascular procedure was 98%, with 48% of patients receiving F-P stents. The AFS was 90%, primary patency 84%, assisted primary patency 88%, and binary restenosis 44% all at 1 year. A significantly greater total volume of calcified plaque (1.1 [.01-3.2] cm(3) vs. .11 [0-1.86] cm(3), p < .001) was found in patients developing restenosis (>50%) compared with those who did not. Patients with a calcified plaque volume greater than 1.1 cm(3) had a significantly worse AFS than those with a volume less than 1.1 cm(3) (p = .0038). Multivariate analysis showed that the percentage calcified plaque (p = .003, HR 11.4, 95% CI 1.45-37.29) was an independent predictor of binary restenosis at 12 months, and that absolute volume of calcified plaque (p = .001, HR 3.56, 95% CI 1.64-7.7) was independently associated with AFS. CONCLUSIONS The burden of calcified plaque, but not soft or fibrocalcific plaque is related to restenosis, reintervention, and AFS. Computed tomography plaque analysis may form an important non-invasive tool for risk stratification in patients undergoing F-P endovascular procedures.

Abstract
Trying to conceive and being pregnant is an emotional period for those involved. In the majority of patients suffering from inflammatory bowel disease, maintenance therapy is required during pregnancy to control the disease, and disease control might necessitate introduction of new drugs during a vulnerable period. In this updated consensus on the reproduction and pregnancy in inflammatory bowel disease reproductive issues including fertility, the safety of drugs during pregnancy and lactation are discussed.

Abstract
A systematic review was performed to provide a qualitative analysis and quantitative data synthesis of randomized controlled trials (RCTs) assessing debulking atherectomy versus balloon angioplasty for treatment of femoropopliteal artery occlusive disease. PubMed (MEDLINE), EMBASE, AMED, Scopus, online content and meeting abstracts were searched in May 2014 for eligible RCTs following the PRISMA selection process. Risk of bias was assessed using the Cochrane Collaboration's tool. Pooled risks were calculated with a random effects model to account for clinical and conceptual heterogeneity. Sensitivity analysis was employed to test the robustness of the results. Six RCTs comprising 287 patients (328 lesions) treated with either debulking atherectomy or balloon angioplasty for femoropopliteal artery disease were analyzed and synthesized. Technical success was similar between the atherectomy and the angioplasty group (93.6% vs. 96.2%, RR: 0.99. 95%CI: 0.95-1.03, P=0.57, I(2)=0%). Need for bail-out stenting and distal arterial embolization were largely similar between atherectomy and balloon angioplasty alone. After a median follow-up of 9 months the 2 groups showed similar primary patency (RR: 0.90, 95%CI: 0.56-1.46, P=0.68, I(2)=69%). Only 2 low-quality studies reported amputation and mortality rates, both of which were found significantly less in the atherectomy arms. Analysis of a limited body of low quality evidence with high risk of bias showed that debulking atherectomy of the femoropopliteal artery does not seem to confer any procedural advantage or improvement of clinical outcomes over balloon angioplasty alone.

Abstract
AIM Aim of the present study was to report the imaging and clinical outcomes of a prospective single-center study investigating paclitaxel-coated balloons (PCB) for the treatment of failing peripheral bypass grafts (BYPACS study). METHODS In total, 32 patients had their failing peripheral native or synthetic bypass graft treated with PCB angioplasty (Group PCB). Basic inclusion criteria were any significant proximal or distal anastomotic stenosis confirmed by Duplex ultrasound (DUS; PSVR>2.5) associated with significantly reduced in-graft velocities (<45 cm/s) putting the graft at risk of thrombosis. Results were compared with a similar historical control group of 24 patients who had their failing peripheral bypass treated with plain uncoated balloon angioplasty (Group PTA). Primary endpoint was binary lesion restenosis defined as >50% stenosis of the treated lesion on DUS. Secondary endpoints included freedom from target lesion revascularization (TLR) defined as a patent peripheral bypass graft regardless of restenosis but without any repeat intervention (driven by reduced in-graft velocities <45 cm/s), major amputations and graft thrombosis. Multivariable Cox proportional hazards regression analysis was applied to adjust for confounding factors of heterogeneity. Results are reported as Cox-adjusted hazard ratios (HR and 95% CI). RESULTS Baseline variables were equally distributed between the two groups. Median follow-up was 7 months in group PCB and 8 months in group PTA. Rates of binary restenosis were similar between the 2 groups (HR=1.08, 95% CI=0.49-2.40; P=0.84). Freedom from TLR was also similar (HR=0.97, 95% CI=0.36-2.66; P=0.88). One amputation occurred in the PCB group and 2 in the PTA (P=0.58). Four events of bypass thrombosis occurred in each group (P=0.71). CONCLUSION PCB does not significantly inhibit restenosis or improve freedom from repeat angioplasty after treatment of failing peripheral arterial vein or synthetic bypass grafts.

Abstract
PURPOSE A systematic review was undertaken to provide a meta-analysis of clinical trials comparing thermal ablation with surgical nephrectomy for small renal tumours. METHODS PubMed (MEDLINE), EMBASE, AMED, and Scopus were searched in August 2013 for eligible prospective or retrospective comparative trials following the PRISMA selection process. Thermal ablation was compared with surgical nephrectomy. Quality of included studies was assessed on the Newcastle-Ottawa Scale (NOS). The primary endpoint was disease-free survival and was analyzed on the log-hazard scale. Secondary outcome measures included complications, local recurrence, and decline of renal function. Hazard ratios (HR) and risk ratios (RR) were calculated with a random effects model, and meta-regression analysis was performed to explore clinical heterogeneity. RESULTS Six clinical trials (1 randomized and 5 cohort; 6-8 stars on the NOS scale) involving 587 patients with small renal tumors (mean size 2.5 cm) treated with either thermal ablation (percutaneous or laparoscopic application of radiofrequency or microwave) or surgical nephrectomy (open or laparoscopic) were analyzed. Overall complication rate was significantly lower in the ablation group (7.4 vs. 11%; RR: 0.55, 95% confidence interval [CI]: 0.31-0.97, p = 0.04). Postoperative decline of eGFR was higher in case of nephrectomy (mean difference: -14.6 ml/min/1.73 m(2), 95% CI: -27.96 to -1.23, p = 0.03). Local recurrence rate was the same in both groups (3.6 vs. 3.6%; RR: 0.92, 95% CI: 0.4-2.14, p = 0.79) and disease-free survival also was similar up to 5 years (HR: 1.04, 95% CI: 0.48-2.24, p = 0.92). CONCLUSIONS Thermal ablation of small renal masses produces oncologic outcomes similar to surgical nephrectomy and is associated with significantly lower overall complication rates and a significantly less decline of renal function. More randomized, controlled trials are necessary.

Abstract
BACKGROUND Worldwide, 480-520 million people are chronically infected with hepatitis B or C virus. In addition to their effects in the liver, chronic hepatitis viral infections may have serious extra hepatic manifestations. These manifestations have been more widely studied in chronic HCV infection, where they are more frequently described, but they have been also reported chronic HBV infection. AIM Among those, of great interest are the ocular manifestations caused by the HBV or HCV infection or induced by chronic hepatitis therapy. These we attempted to review. MATERIALS AND METHODS A PubMed search was conducted using the terms hepatitis, ocular, eye. RESULTS This article describes the ocular symptoms related to HBV and HCV hepatitis such as xerophthalmia, Mooren's ulcer and retinopathy as well as other rare manifestations caused by either the infection or the therapy. CONCLUSIONS The ocular manifestations of HCV infections best supported by the literature include a dry eye syndrome similar to Sjögren's syndrome, and ischemic retinopathy caused by either HCV-induced vasculitis or treatment with interferon. There are no serious ocular manifestations of HBV infection other than dry eye syndrome. Special consideration should be held for possible connection between HBV vaccine and uveitis.

Abstract
Modern critical limb ischemia management algorithms endorse an "endovascular first" strategy of treatment. The advent of stents coated with anti-restenotic agents that are gradually eluted to the vessel wall has revolutionized modern endovascular therapies. Several single-center, non-randomized cohort series have provided compelling data about the short- to mid-term safety and effectiveness of drug-eluting stents in below-the-knee lesions and have fuelled further large-scale research. Three multicenter randomized trials (the YUKON-BTX, the DESTINY and the ACHILLES trials) are now available and have paved the way for level I-A evidence about infrapopliteal use of drug-eluting stents. Amassed evidence strongly supports the use of olimus-eluting metal stents for focal obstructive infrapopliteal lesions in order to inhibit restenosis, prolong vessel patency and thereby achieve sustained patient improvement, as reflected by the significantly improved Rutherford-Becker classification, reduced number of repeat procedures and a trend towards improved wound healing. The present overview outlines current evidence about clinical outcomes after below-the-knee drug-eluting stent placement compared to more traditional endovascular treatments like conventional old balloon angioplasty and bare metal stents. Available evidence is appraised in the context of clinically meaningful results and relevant unresolved issues are highlighted.

Abstract
A 51-year-old male was referred to the University Eye Clinic of Ioannina with nonarteritic anterior ischemic optic neuropathy (NAION) 12 hours after receiving sildenafil citrate (Viagra(®)). Examination for possible risk factors revealed mild hypercholesterolemia. Family history showed that his father had suffered from bilateral NAION. Although a cause-and-effect relationship is difficult to prove, there are reports indicating an association between the use of erectile dysfunction agents and the development of NAION. Physicians might need to investigate the presence of family history of NAION among systemic or vascular predisposing risk factors before prescribing erectile dysfunction drugs.

Abstract
AIM To present the results of a prospective, randomized, single-centre study investigating local anaesthesia before percutaneous common femoral artery (CFA) puncture and catheterization with the use of ultrasound-guided injection of lidocaine versus standard infiltration by manual palpation. MATERIALS AND METHODS Patients scheduled to undergo diagnostic or therapeutic transfemoral catheter-based procedures gave informed consent and were randomized in two groups. In the first arm local anaesthesia with lidocaine hydrochloride 1% was performed under ultrasound guidance (group U/S), while in the second arm the standard method of manual artery palpation was applied (group M). In both groups, subsequent CFA catheterization was achieved under ultrasound guidance. The primary study endpoint was peri-procedural pain level evaluated with a visual-analogue scale (VAS score 0-10). RESULTS Between January 2009 and 2010, 200 patients (161 men, mean age 63±12 years) were equally assigned to each group without any significant differences in baseline demographics. Patients in group U/S experienced significantly less pain during CFA catheterization in comparison with group M with a difference of three points in mean VAS score reported (1.6±1.6 versus 4.6±1.9, p<0.0001). In addition, significantly less volume of lidocaine was used in group U/S compared to group M (16±2.7 versus 19±0.8ml, p<0.001).Total vascular access time was similar in both groups (4.4±1.3 versus 4.5±1.3min). Overall complications included two small groin haematomas in each group. CONCLUSION Ultrasound-guided local anaesthesia of the CFA prior to percutaneous transcatheter procedures is safe and achieves superior levels of analgesia with minimal patient pain and discomfort compared to the standard method of manual palpation.

Abstract
BACKGROUND AND AIMS This study evaluates the long-term safety of infliximab in patients with inflammatory bowel disease (IBD) treated with the drug over a 14-year period. METHODS The medical records of 734 patients with IBD treated with infliximab and 666 control patients not treated with infliximab were reviewed for adverse events. The time of onset and outcome, severity and concomitant medication were recorded. RESULTS Patients and controls were followed up for serious adverse events for a median time of 58 months (IQR 33-88) and 144 months (IQR 83-163), respectively. 112 severe adverse events occurred in 93 patients (13%) treated with infliximab and 157 occurred in 126 (19%) control patients (OR 1.33 (95% CI 0.56 to 3.00, p = 0.45). There was no difference between the two groups in mortality, malignancies and infection rate. Tuberculosis was diagnosed in two patients receiving infliximab who had negative skin tests at baseline whereas none of 16 patients with positive skin tests who received prophylaxis developed tuberculosis. Concomitant treatment with steroids was the only independent risk factor for infections in patients treated with infliximab (OR 2.69 (95% CI 1.18 to 6.12), p = 0.018). The most commonly observed systemic side effects were skin eruptions including psoriasiform eruptions in 150 patients (20%). CONCLUSIONS Long-term infliximab treatment had a good overall safety profile in the patient cohort studied.

Abstract
BACKGROUND AND AIMS Communication to patients of information about their disease has become increasingly important in modern medicine, and particularly with chronic nonfatal disorders like inflammatory bowel disease (IBD), but the subject is not adequately researched or understood. METHODS We studied the media and preferences for communication of information in a multi-national community-based inception cohort of European and Israeli patients with IBD and 10 years follow-up, using structured questionnaires categorizing demographics, disease status, current and preferred sources of information, use of electronic media, role of patients' associations, and satisfaction level. RESULTS The 917 patients completing the questionnaire were derived from northern (60%) and southern (40%) countries. The mean age was 48.3 years (62% under 50 years); 51% were males; 67% had ulcerative colitis, 33% Crohn's disease. Sixty-six percent of patients designated the specialist as their primary source of information, 77% indicated satisfaction with their current information, and 65% reported not receiving information about medical treatment in the past year. Patient concerns were about new research into their illness (64%), medical treatments (58%), risks and complications (51%) and genetics (42%). Preferred sources of information were paper bulletin (76%), electronic media (30%) and international organization (79%). Diagnosis (ulcerative colitis or Crohn's disease), gender, education level and country impacted significantly on patients' choices. CONCLUSIONS In providing health care information to patients with IBD their individual attitudes and preferences must be considered. There should be greater roles for IBD patients' associations and international IBD-research organizations, and an increasing use of electronic media.

Abstract
Iodinated contrast media (CM) are widely used in diagnostic imaging and therapeutic interventional procedures of everyday clinical practice and are associated with multiple hemodynamic and hemorheological effects. The purpose of our work was to investigate the red blood cell (RBC) rheological properties after in vivo administration of low-osmolar or iso-osmolar CM by measuring their membrane deformability (Index of Rigidity, IR) using a filtration method. Blood samples were taken from patients who underwent digital subtraction angiography of the peripheral arteries at various times before and after intravenous administration of CM. CM included iso-osmolar Iodixanol, low-osmolar Iopromide and low-osmolar Iopentol. In the whole patient group an IR increase of 59% was calculated 5 minutes after administration of CM followed by a normalization of elevated IR values within the following hour. The 5-min IR increase was strongest in the group treated with Iopromide, whereas administration of Iodixanol was associated with a more modest transient IR increase. Intravenous injection of CM in humans may be associated with a transient but considerable decrease of RBC membrane deformability and particularly for the iso-osmolar CM the induced changes in membrane deformability seem to be more moderate.

Abstract
PURPOSE To report the safety and efficacy of percutaneous nephrostomy and primary antegrade recanalization for treatment of iatrogenic ureteral strictures after gynecologic surgery. PATIENTS AND METHODS Ten women had symptoms suggestive of ureteral obstruction during the immediate postoperative period (5 days-1 week after surgery). Under analgesia and conscious sedation, standard percutaneous nephrostomy was performed, and a long 7F sheath was placed in the upper ureter. The obstructions were traversed with the aid of a 0.0035-inch Glidewire and a 5F angled Glide catheter (Terumo, Japan). Subsequently, the areas were dilated with angioplasty balloons to a maximum diameter of 7 mm. Finally, an 8F percutaneous internal/external nephroureteral drainage stent was inserted to secure ureteral patency. Follow-up was carried out by serial nephrostomography until removal of the stent and by renal ultrasonography thereafter. RESULTS Twelve obstructions with a mean length of 1.4 cm (range 0.4-1.9 cm) were managed. The technical success rate was 100%. No major complications occurred, and normal renal function was restored. The mean follow-up was 12 months. In 60% of the patients, a patent ureter was depicted at 1 week, whereas in four patients, repeat dilation of the obstructed segment was required. The stents were removed after a mean period of 4.8 weeks. CONCLUSION Percutaneous nephrostomy and primary antegrade ureteral balloon dilation is safe and efficacious for treating ureteral injury after pelvic surgery and obviates open surgical manipulations.

Abstract
AIMS To determine the long-term response to interferon-alpha therapy in patients with hepatitis B e antigen-negative chronic hepatitis B, and the factors independently associated with response and survival. METHODS Sixty-three patients with documented hepatitis B e antigen-negative chronic hepatitis B treated with interferon-alpha for a year were followed-up for a period of 6 years. RESULTS Sustained biochemical and virological response was seen in 34.91% and 33.33% of patients at 6 and 12 months of follow-up, respectively, and histological improvement in 54.5% of sustained responders compared with non-responders (7.1%, P = 0.004, chi-squared test), at 6 months of follow-up. Multivariate analysis showed that patients with hepatitis B virus-DNA levels at 6 months of treatment <10,000 copies/mL had a low probability of relapse, compared with those with levels >10 000 copies/mL (P = 0.032). Age (>65 years) and hepatitis B virus-DNA level at 6 months of treatment (>10,000 copies/mL) were the independent factors for disease progression and survival (P = 0.041 and P = 0.044 respectively). At 6 years, a sustained response was still present in 19.04% of patients and 4.8% of them had developed anti-HBs. CONCLUSION Hepatitis B virus-DNA monitoring by quantitative polymerase chain reaction at 6 months of treatment may allow for early prediction of response to interferon-alpha, and may serve as an indicator of disease progression in the future.
