Antibiotic Use Without a Prescription: A Multisite Survey of Patient, Health System, and Encounter Characteristics.

BACKGROUND: Using antibiotics without a prescription is potentially unsafe and may increase the risk of antimicrobial resistance. We evaluated the effect of patient, health system, and clinical encounter factors on intention to use antibiotics without a prescription that were (1) purchased in the United States, (2) obtained from friends or relatives, (3) purchased abroad, or (4) from any of these sources. METHODS: The survey was performed January 2020-June 2021 in 6 publicly funded primary care clinics and 2 private emergency departments in Texas, United States. Participants included adult patients visiting 1 of the clinical settings. Nonprescription use was defined as use of antibiotics without a prescription; intended use was professed intention for future nonprescription antibiotic use. RESULTS: Of 564 survey respondents (33% Black and 47% Hispanic or Latino), 246 (43.6%) reported prior use of antibiotics without a prescription, and 177 (31.4%) reported intent to use antibiotics without a prescription. If feeling sick, respondents endorsed that they would take antibiotics obtained from friends/relatives (22.3% of 564), purchased in the United States without a prescription (19.1%), or purchased abroad without a prescription (17.9%). Younger age, lack of health insurance, and a perceived high cost of doctor visits were predictors of intended use of nonprescription antibiotics from any of the sources. Other predictors of intended use were lack of transportation for medical appointments, language barrier to medical care, Hispanic or Latino ethnicity, and being interviewed in Spanish. CONCLUSIONS: Patients without health insurance who report a financial barrier to care are likely to pursue more dangerous nonprescription antimicrobials. This is a harm of the US fragmented, expensive healthcare system that may drive increasing antimicrobial resistance and patient harm.

Bevacizumab in combination with octreotide rescues a patient with liver cirrhosis, GAVE syndrome and refractory hemorrhage - a case report.

Gastric antral vascular ectasia (GAVE) syndrome is a rare but often challenging etiology of upper gastrointestinal bleeding (UGIB).We report on a 60-year-old patient with liver cirrhosis, GAVE syndrome and recurrent and refractory GAVE-related UGIB. During a 5-month hospital stay, the patient required a total of 82 packed red blood cells (pRBCs) and 23 gastroscopies. All endoscopic approaches, including multiple argon plasma coagulation and band ligation sessions, remained unsuccessful. Antrectomy was waived because of the high perioperative mortality risk in Child-Pugh B liver cirrhosis. TIPS insertion also failed to control the bleeding. Only continuous intravenous octreotide infusion slowed the bleeding, but this forced the patient to be hospitalized. After 144 inpatient days, administration of subcutaneous octreotide allowed the patient to be discharged. However, the patient continued to require two pRBCs every 2-3 weeks. Based on recently published data, we treated the patient with bevacizumab (anti-VEGF antibody) off-label at a dose of 7.5 mg/kg body weight every three weeks in nine single doses over six months. Since the first administration, the patient has remained transfusion-free, has not required hospitalization, and leads an active life, working full-time. He remains on octreotide, which has been reduced but not yet discontinued. Additionally, no adverse events were observed.Thus, in patients with liver cirrhosis and refractory GAVE-related hemorrhage, bevacizumab combined with subcutaneous octreotide should be considered as an effective and durable pharmacological treatment option.

Outcomes of preoperative antiplatelet therapy in patients with acute type A aortic dissection.

BACKGROUND: Acute type A aortic dissection (ATAAD) is life-threatening and requires immediate surgery. Sudden chest pain may lead to a risk of misdiagnosis as an acute coronary syndrome and may lead to subsequent antiplatelet therapy (APT). We used the Chinese Acute Aortic Syndrome (AAS) Collaboration Database to study the effects of APT on clinical outcomes. METHODS: The AAS database is a retrospective multicentre database where 31 of 3092 patients had APT with aspirin or clopidogrel or both before surgery. Before and after propensity score matching (PSM), the incidence of complications and mortality was compared between APT and non-APT patients by using a logistic regression model. The sample remaining after PSM was 30 in the APT group and 80 in the non-APT group. RESULTS: The sample remaining after matching was 30 in the APT group and 80 in the non-APT group. We found 10 cases with percutaneous coronary intervention in the APT group (33.3%). The APT group received more volume of packed red blood cells, 8.4 ± 6.05 units; plasma, 401.67 ± 727 ml, and platelet transfusion (14.07 ± 8.92 units). The drainage volume was much more in the APT group (5009.37 ± 2131.44 ml, p = .004). Mortality was higher in APT group (26% vs. 10%, p = .027). The preoperative APT was an independent predictor of mortality (odds ratio: 6.808, 95% confidence interval: 1.554-29.828, p = .011). CONCLUSION: APT before ATAAD repair was associated with more transfusions and higher early mortality. The timing of surgery should be carefully considered based on the patient's status and the surgeon's experience.

Low-level laser therapy as an adjunct to conventional therapy in the treatment of diabetic foot ulcers.

Foot ulcers are serious complications of diabetes mellitus (DM) and are known to be resistant to conventional treatment. This study was conducted to evaluate the efficacy of low-level laser therapy (LLLT) for the treatment of diabetic foot ulcers in a tertiary care centre (Department of Surgery, Mahatma Gandhi Memorial Medical College and Maharaja Yashwantrao Hospital, A.B. Road, Indore). A total of 30 patients with type 2 DM having Meggitt-Wagner grade I foot ulcers of more than 6 weeks duration with negative culture were studied. Patients were randomized into two groups of 15 each. Patients in study group received LLLT (660 ± 20 nm, 3 J/cm2) along with conventional therapy and those in control group were treated with conventional therapy alone. The primary outcome measure was the absolute and relative wound size reduction at 2 weeks compared to the baseline parameter. Percentage ulcer area reduction was 37 ± 9% in the LLLT group and 15 ± 5.4% in the control group (p < 0.001). For ∼75% of wounds of the treatment group, wound area reduction of 30-50% was observed. In contrast, for the control group, ∼80% of wounds showed a wound area reduction of <20% on day 15. Further, the wounds with initial wound area 1000-2000 mm2 seems to have better final outcome than the groups with larger areas. The treated groups showed higher amount of granulation than the control group. The results suggest that LLLT is beneficial as an adjunct to conventional therapy in the treatment of diabetic foot ulcers.

Single-stage preputial skin flap urethroplasty for long-segment urethral strictures: evaluation and determinants of success.

OBJECTIVE: To determine the overall efficacy and predictors of success of the penile preputial flap in the management of complex urethral strictures >2.5 cm in length. PATIENTS AND METHODS: We performed a retrospective and prospective study of 58 patients undergoing single-stage penile preputial flap urethroplasty for complex long-segment urethral strictures, without lichen sclerosus, repaired between May 2005 and April 2012 at our institution. For obvious reasons circumcised patients were excluded from the study. Results were assessed by univariate analysis of various patient characteristics, preoperative and postoperative patient satisfaction (based on symptoms), and urethral ultrasonography, retrograde urethrography and uroflowmetry. RESULTS: The median (range) follow-up was 42 (6-90) months, the median (range) intra-operative stricture length was 48.5 (26-85) mm and the median (range) operating time was 90 (85-125) min. A total of 87.93% of patients had a satisfactory outcome, with an overall success rate of 81.03%. Diabetes mellitus (relative risk [RR] 5.21, confidence interval [CI] 2.31-64.68, P = 0.003) and smoking (RR 4.19, CI 1.54- 45.0, P = 0.01) were predictors of failure, while postinfective aetiology (RR 2.19), panurethral stricture (RR 2.73), stricture length >70 mm (RR 3.25), previous urethroplasty (RR 2.4) and severe peri-urethral fibrosis (RR 2.37) were also associated with a higher risk of failure. CONCLUSIONS: A urologist should try to gain experience of all the methods of urethroplasty as the techniques may vary according to the circumstances. Single-stage preputial skin flap urethroplasty, in experienced and expert hands, has results equivalent to all other methods of urethroplasty in complex urethral strictures. We prefer this technique in this part of the world where buccal mucosa cannot be used because of dyskeratotic changes as a result of consumption of gutkha, tobacco, pan masala, betel nut.

Comprehensive analysis of etiology on the prognosis of urethral strictures.

INTRODUCTION: Urethral strictures remain a reconstructive dilemma, due to high incidence of recurrence and less than satisfactory outcomes. Even experienced surgeons following strict surgical principles have not achieved optimal results, leading us to think whether the etiology of strictures dictate the outcome . We evaluated this "cause-effect" relationship highlighting the significance of the etiology on the overall prognosis of urethral strictures. MATERIALS AND METHODS: A total of 302 males with urethral strictures were assessed (both retrospectively and prospectively) over a period of ten years. The preoperative evaluation was performed by retrograde urethrogram, urethrosonogram, and uroflowmetry and categorized, based on etiology: a) as post traumatic, b) post infective, c) iatrogenic or d) unknown. Traumatic strictures were subjected to pelvic X-ray and sub-categorized into grades A, B and C, following the TILE classification. Patients were operated; with tunica albuginea urethroplasty for anterior strictures and U shape prostato-bulbar anastomosis for posterior strictures. RESULTS: Traumatic strictures accounted for 54% of cases. 127 of the 302 patients were treated using Tunica Albuginea Urethroplasty, while U shaped Prostatobulbar Anastomosis was performed on others. Post traumatic strictures had best outcome whereas post infective strictures had the worse outcome. Among strictures following pelvic fractures, TILE grades A and B had a better post operative course as compared to TILE C. Overall complication rate was 13.24%. CONCLUSION: Our study demonstrated that etiology of urethral strictures may play a vital role for the overall prognosis of urethral strictures.

Uptake, accumulation and elimination of cadmium in a soil - Faba bean (Vicia faba) - Aphid (Aphis fabae) - Ladybird (Coccinella transversalis) food chain.

Cadmium is a highly mobile toxic heavy metal and a serious hazard to the biosphere. We studied uptake, accumulation and elimination of cadmium in a soil - faba bean - aphid - ladybird food chain. The soil in the study was amended with Cd at concentrations 0, 5, 10, 20 and, 30 mg kg-1 (w/w). We noted significant Cd transfer in a dose-dependent manner. Cadmium biomagnified in faba bean roots and aphids while biominimized in ladybirds as revealed by their respective transfer coefficients. The concentration-dependent removal of Cd from aphids through excretion via honeydew as well as through pupal exuviae of ladybirds during metamorphosis links to possible mechanisms of Cd detoxification at these trophic levels, which regulates the bioaccumulation of Cd along the food chain. These findings press for the advance studies to find and understand the physiological pathways and mechanisms leading to bio-minimization of Cd across the food chain.

Case-based audit and feedback around a decision aid improved antibiotic choice and duration for uncomplicated cystitis in primary care clinics.

OBJECTIVES: The objective of our study was to evaluate the impact of a multifaceted stewardship intervention on adherence to the evidence-based practice guidelines on treatment of uncomplicated cystitis in primary care. We hypothesised that our intervention would increase guideline adherence in terms of antibiotic choice and duration of treatment. DESIGN: A preintervention and postintervention comparison with a contemporaneous control group was performed. During the first two study periods, we obtained baseline data and performed interviews exploring provider prescribing decisions for cystitis at both clinics. During the third period in the intervention clinic only, the intervention included a didactic lecture, a decision algorithm and audit and feedback. We used a difference-in-differences analysis to determine the effects of our intervention on the outcome and guideline adherence to antibiotic choice and duration. SETTING: Two family medicine clinics (one intervention and one control) were included. PARTICIPANTS: All female patients with uncomplicated cystitis attending the study clinics between 2016 and 2019. RESULTS: Our sample included 932 visits representing 812 unique patients with uncomplicated cystitis. The proportion of guideline-adherent antibiotic regimens increased during the intervention period (from 33.2% (95% CI 26.9 to 39.9) to 66.9% (95% CI 58.4 to 74.6) in the intervention site and from 5.3% (95% CI 2.3 to 10.1) to 17.0% (95% CI 9.9 to 26.6) in the control site). The increase in guideline adherence was greater in the intervention site compared with the control site with a difference-in-differences of 22 percentage points, p=0.001. CONCLUSION: A multifaceted intervention increased guideline adherence for antibiotic choice and duration in greater magnitude than similar trends at the control site. Future research is needed to facilitate scale-up and sustainability of case-based audit and feedback interventions in primary care.

Interaction of ZnO nanoparticle and AM fungi mitigates Pb toxicity in wheat by upregulating antioxidants and restricted uptake of Pb.

The study aims at investigating the efficacy of individual as well as combined application of AM fungi (Glomus macrocarpum) and ZnO nanoparticles on the uptake of lead and its toxicity in wheat (Triticum aestivum L.). The plants were grown in pots with different treatments of AM Fungi, ZnO NP, and Pb. The individual applications of AM fungi (Glomus macrocarpum) and ZnO NPs increased the growth and biochemical attributes of wheat and decreased the Pb uptake under Pb stress. The combined application of AM fungi (Glomus macrocarpum) and ZnO nanoparticles synergistically enhanced the overall growth performance of the plant and significantly reduced the uptake of Pb in wheat grown in Pb spiked soils. The combined application was effective, with 30.66 % increase in plant height, 30.62 % increase in plant fresh weight, 54.26 % increase in plant dry weight, 45.45 % increase in total chlorophyll content, 19.59 % increase in proline content, 26.65 % higher activity of SOD, 15.12 % higher activity of catalase (CAT), 17.69 % increase in H2O2 content, 17.69 % increase in lipid peroxidation content, 52.09 % and 58.19 % decrease in Pb concentration in root and shoot of wheat, respectively, grown in Pb spiked soil (100 mg kg-1 soil). The results indicate that combined application of AM fungi and ZnO nanoparticles can be a promising technique for the utilization of Pb-contaminated soils.

Aortic and mitral valve surgery for infective endocarditis with reconstruction of the intervalvular fibrous body: an analysis of clinical outcomes.

BACKGROUND: Reconstruction of the aorto-mitral curtain (AMC) for invasive double-valve infective endocarditis (IE) is a rare and challenging procedure. This study presents the short- and mid-term results of reconstruction of AMC in a single center. METHODS: From 2016 to 2019, 14 patients with invasive double-valve underwent surgical reconstruction of the AMC, along with either double valve replacement or aortic valve replacement with mitral valve repair. Two patients were diagnosed as Behcet's disease. Bicuspid aortic valve was detected in six patients. Mean follow up was 18.9±12.2 months. RESULTS: Positive blood culture was found in 10 (71.4%) patients: 3 of Abiotrophia defective (21.4%). The mean cardiopulmonary bypass (CPB) time was 154.5±25.9 minutes and the mean cross-clamp time was 116.8±18.2 minutes. One patient died of multiple organ failure (7.1%) 60 days after surgery. There was 1 (7.1%) case of stroke, 1 (7.1%) of atrioventricular block with pacemaker implantation, 1 (7.1%) of reoperation for bleeding. There was no late death during follow-up. The survival at 3 years was 92.9%. Freedom from reoperation at 1, 2, and 3 years was 100%, 100%, and 100% during follow-up, respectively. CONCLUSIONS: The double-valve replacement and AMC reconstruction (the Commando procedure) is an effective technique in complex heart valve disease. The short- and mid-term results with this technique are optimal, with a very low in-hospital mortality and nearly 100% of long-term survival during follow-up.

Validating Use of Electronic Health Data to Identify Patients with Urinary Tract Infections in Outpatient Settings.

OBJECTIVE: To validate the use of electronic algorithms based on International Classification of Diseases (ICD)-10 codes to identify outpatient visits for urinary tract infections (UTI), one of the most common reasons for antibiotic prescriptions. METHODS: ICD-10 symptom codes (e.g., dysuria) alone or in addition to UTI diagnosis codes plus prescription of a UTI-relevant antibiotic were used to identify outpatient UTI visits. Chart review (gold standard) was performed by two reviewers to confirm diagnosis of UTI. The positive predictive value (PPV) that the visit was for UTI (based on chart review) was calculated for three different ICD-10 code algorithms using (1) symptoms only, (2) diagnosis only, or (3) both. RESULTS: Of the 1087 visits analyzed, symptom codes only had the lowest PPV for UTI (PPV = 55.4%; 95%CI: 49.3-61.5%). Diagnosis codes alone resulted in a PPV of 85% (PPV = 84.9%; 95%CI: 81.1-88.2%). The highest PPV was obtained by using both symptom and diagnosis codes together to identify visits with UTI (PPV = 96.3%; 95%CI: 94.5-97.9%). CONCLUSIONS: ICD-10 diagnosis codes with or without symptom codes reliably identify UTI visits; symptom codes alone are not reliable. ICD-10 based algorithms are a valid method to study UTIs in primary care settings.

Trophic transfer and bioaccumulation of lead along soil-plant-aphid-ladybird food chain.

Lead (Pb) contamination of agroecosystems is a serious issue as Pb is a persistent pollutant that is retained in soil for long, causing toxicities to organisms. This study examines biotransfer of Pb from soils treated with different concentrations of Pb through a broad bean (Vicia faba L.)-aphid (Aphis fabae Scop.)-ladybird (Coccinella transversalis Fabricius) food chain and its consequent inference for natural biological control, the ladybird. The soil was amended with Pb at the rates of 0, 25, 50, 75 and 100 mg kg-1 (w/w). The amount of Pb in plant, aphid and ladybird increased in a dose-dependent manner to Pb contents in the soil. The results showed that Pb biomagnified from soil to root with transfer coefficient always > 1. Biominimization of Pb occurred at the second trophic level in aphids and at the third trophic level in ladybirds as their respective transfer coefficients from shoot to aphid and aphid to ladybird were always < 1. The increased elimination of Pb via aphid excreta (honeydew) and pupal exuviae in a dose-dependent manner suggests that these are possible detoxification mechanisms at two different trophic levels which control Pb bioaccumulation along the food chain. The statistically significant (p ≤ 0.05) decreases in biomass and predation rate of predatory ladybirds at 100 mg kg-1 Pb indicate that high dose of Pb in soil may have sub-lethal effects on ladybirds. Further studies at cellular and sub-cellular levels are needed to further document the potential mechanisms of achieving Pb homeostasis in ladybirds under Pb stress.

Qualitative Analysis of Primary Care Provider Prescribing Decisions for Urinary Tract Infections.

Inappropriate choices and durations of therapy for urinary tract infections (UTI) are a common and widespread problem. In this qualitative study, we sought to understand why primary care providers (PCPs) choose certain antibiotics or durations of treatment and the sources of information they rely upon to guide antibiotic-prescribing decisions. We conducted semi-structured interviews with 18 PCPs in two family medicine clinics focused on antibiotic-prescribing decisions for UTIs. Our interview guide focused on awareness and familiarity with guidelines (knowledge), acceptance and outcome expectancy (attitudes), and external barriers. We followed a six-phase approach to thematic analysis, finding that many PCPs believe that fluoroquinolones achieve more a rapid and effective control of UTI symptoms than trimethoprim-sulfamethoxazole or nitrofurantoin. Most providers were unfamiliar with fosfomycin as a possible first-line agent for the treatment of acute cystitis. PCPs may be misled by advanced patient age, diabetes, and recurrent UTIs to make inappropriate choices for the treatment of acute cystitis. For support in clinical decision making, few providers relied on guidelines, preferring instead to have decision support embedded in the electronic medical record. Knowing the PCPs' knowledge gaps and preferred sources of information will guide the development of a primary care-specific antibiotic stewardship intervention for acute cystitis.

Assessment of biotransfer and bioaccumulation of cadmium, lead and zinc from fly ash amended soil in mustard-aphid-beetle food chain.

The present study investigates the extent of biotransfer and bioaccumulation of cadmium (Cd), lead (Pb) and zinc (Zn) from fly ash amended soil in mustard (Brassica juncea)-aphid (Lipaphis erysimi)-beetle (Coccinella septempunctata) food chain and its subsequent implications for the beetle. The soil was amended with fly ash at the rates of 0, 5, 10, 20 and 40% (w/w). Our results showed that the uptake of Cd, Pb and Zn from soil to mustard root increased with the increase in fly ash application rates, but their root to shoot translocation was relatively restricted. Increase in chlorophyll content and dry mass of mustard plant on treatments ≥20% even at elevated accumulation of Cd (1.67mgkg-1), Pb (18.25mgkg-1) and Zn (74.45mgkg-1 dry weight) in its shoot showed relatively higher tolerance of selected mustard cultivar to heavy metal stress. The transfer coefficient (TC1) of Cd from mustard shoot to aphid was always >1, indicating that Cd biomagnified in aphids at second trophic level. But, there was no biomagnification of Cd in adult beetles at third trophic level. Zinc accumulation was 2.06 to 2.40 times more in aphids than their corresponding host shoots and 1.26-1.35 times more in adult beetles than their prey (aphids) on which they fed. Lead was only metal whose TC was <1 at both second and third trophic levels. The elimination of Cd via honeydew of aphids was most efficient as the ratio of metal in honeydew to aphid (ranging from 0.21 to 0.26) was higher than the Pb (0.16 to 0.20) and Zn (0.07 to 0.09). The statistically consistent (p>0.05) biomass and predation rate of predatory beetles indicated that all levels of soil amendments with fly ash did not have any lethal or sub-lethal effects on beetles.

Evaluating efficacy of various operative procedures done in anterior urethral stricture using urethral stricture score.

CONTEXT: Scoring systems have been an important tool of clinical decision making in medicine. As scoring systems like Glasgow Coma scale have made a revolutionary change in stratifying the patient, in particular, clinical scenario. Wiegand et al. in 2012 proposed UREThRAL Score a novel method to quantify anterior urethral stricture. AIMS: The aim was to validate urethral stricture score (USS) for evaluating the efficacy of operative procedures. SETTINGS AND DESIGN: Study was done in a retrospective manner and includes patients operated for anterior urethral stricture by a single surgeon in tertiary care center over the period of 2008-2014. SUBJECTS AND METHODS: A total of 57 cases were included in this study who met the inclusion criteria, of these cases 7 underwent excision and primary anastomosis (EPA), 20 underwent preputial flap urethroplasty (PFUP), 22 underwent tunica albuginea urethroplasty (TAU), and rest 8 underwent scrotal flap urethroplasty (SFUP). Procedures were assigned different complexity level, and USS was compared with the particular procedure to see the relation between both. STATISTICAL ANALYSIS USED: Data were analyzed using ANOVA on SPSS software. RESULTS: Mean USS for EPA, PFUP, TAU, and SFUP in our study group was found to be 6.57, 8.95, 9.00, and 10.00, respectively, with an overall USS of 9.03, with a standard deviation of 1.56. USS was significantly associated with complexity. CONCLUSIONS: Mean USS increased with increase in surgical complexity indicating that higher USS correlates with more complex surgery. Strongest association between complexity and the individual parameter was found with location and length.

The transfer and fate of Pb from sewage sludge amended soil in a multi-trophic food chain: a comparison with the labile elements Cd and Zn.

The contamination of agroecosystems due to the presence of trace elements in commonly used agricultural materials is a serious issue. The most contaminated material is usually sewage sludge, and the sustainable use of this material within agriculture is a major concern. This study addresses a key issue in this respect, the fate of trace metals applied to soil in food chains. The work particularly addresses the transfer of Pb, which is an understudied element in this respect, and compares the transfer of Pb with two of the most labile metals, Cd and Zn. The transfer of these elements was determined from sludge-amended soils in a food chain consisting of Indian mustard (Brassica juncea), the mustard aphid (Lipaphis erysimi) and a predatory beetle (Coccinella septempunctata). The soil was amended with sludge at rates of 0, 5, 10 and 20 % (w/w). Results showed that Cd was readily transferred through the food chain until the predator trophic level. Zn was the most readily transferred element in the lower trophic levels, but transfer to aphids was effectively restricted by the plant regulating shoot concentration. Pb had the lowest level of transfer from soil to shoot and exhibited particular retention in the roots. Nevertheless, Pb concentrations were significantly increased by sludge amendment in aphids, and Pb was increasingly transferred to ladybirds as levels increased. The potential for Pb to cause secondary toxicity to organisms in higher trophic levels may have therefore been underestimated.

Prognosis of urethral strictures following pelvic fracture urethral distraction defects--a single centre study.

INTRODUCTION: Urethral strictures remain a reconstructive dilemma due to high incidence of recurrence and unsatisfactory outcomes. Pelvic trauma remains the foremost etiology leading to morbidity. We evaluated this "cause-effect" relationship of pelvic trauma to stricture outcome, to replenish our understanding of contemporary urethral strictures and highlight significance of type, degree and influence of primary management of pelvic trauma on the overall prognosis of urethral strictures. MATERIALS AND METHOD: 163 male patients with urethral strictures, primary etiology being pelvic trauma, were assessed preoperatively followed by retrograde urethrogram, urethrosonogram, uroflowmetry, and then subjected to pelvic radiographs to identify presence and type of pelvic fracture, and further sub-categorize them into grades A, B and C, of TILE classification. Thereafter, 6 weeks later, these patients underwent urethroplasty. RESULTS: Of 163 patients having pelvic trauma, 80 fell under category A of TILE grading, whereas 55 were under TILE B and 28 under TILE C. Most common stricture location was membranous urethra. Success rates were 96-98% till 1 year follow up, but after two years, they declined to 93%. TILE A and B had a better post operative course as compared to TILE C. Overall complication rate was 20.25%. CONCLUSION: The magnitude of the impact of the type of pelvic fracture and its management has remained unexplored. Our representative study enunciates that these parameters play a vital role in the overall prognosis of urethral strictures and command due importance, to bridge the rift in this "cause-effect" relationship.

Comprehensive analysis of etiology on the prognosis of urethral strictures

Even experienced surgeons following strict surgical principles have not achieved optimal results, leading us to think whether the etiology of strictures dictate the outcome . We evaluated this "cause-effect" relationship highlighting the significance of the etiology on the overall prognosis of urethral strictures. MATERIALS AND METHODS: A total of 302 males with urethral strictures were assessed (both retrospectively and prospectively) over a period of ten years. The preoperative evaluation was performed by retrograde urethrogram, urethrosonogram, and uroflowmetry and categorized, based on etiology: a) as post traumatic, b) post infective, c) iatrogenic or d) unknown. Traumatic strictures were subjected to pelvic X-ray and sub-categorized into grades A, B and C, following the TILE classification. Patients were operated; with tunica albuginea urethroplasty for anterior strictures and U shape prostato-bulbar anastomosis for posterior strictures. RESULTS: Traumatic strictures accounted for 54 percent of cases. 127 of the 302 patients were treated using Tunica Albuginea Urethroplasty, while U shaped Prostatobulbar Anastomosis was performed on others. Post traumatic strictures had best outcome whereas post infective strictures had the worse outcome. Among strictures following pelvic fractures, TILE grades A and B had a better post operative course as compared to TILE C. Overall complication rate was 13.24 percent. CONCLUSION: Our study demonstrated that etiology of urethral strictures may play a vital role for the overall prognosis of urethral strictures.
