Evaluation and management of urethral foreign bodies and description of a novel ultrasound?guided catheter?based extraction technique

ABSTRACT: Abstract There are numerous reports in the medical literature documenting urethral foreign bodies with nearly all cases found in men and often associated with underlying psychiatric disorders, autoerotic stimulation, and/or intoxication. Patients most commonly presented with localized penile pain, hematuria, dysuria, and occasionally obstruction. Although endoscopic removal by a urologist is often the first?line treatment, this report describes evaluation and management considerations and presents a novel extraction technique that may allow emergency physicians in consultation with urology to perform removal of some unusual urethral foreign bodies in the emergency department. We report a novel extraction technique using a pediatric foley catheter under ultrasound guidance that has been applied during multiple encounters with 2 individuals who have each presented multiple times at a single emergency department (ED) for evaluation because of urethral foreign body insertion. The foreign body materials have ranged from small pieces of rubber to cellophane to styrofoam and most commonly plastic utensils. Urologic extraction may be required in some cases, but ED removal can be considered. A final discussion of the creation of a multidisciplinary care plan to address resource use concerns also is described.

Project description:Introduction/objectivesThis study aims to describe the procedure and effectiveness of the four-vertex technique for correcting urethral prolapse in women.Methods and materialsincludes a retrospective case series of 17 patients who underwent surgery for urethral prolapse. Two study groups were distinguished based on the presence or absence of pelvic heaviness symptoms. The variables were analyzed, including age, BMI, concomitant diseases, obstetric and gynecological history, time from diagnosis to surgery, and outcomes of treatment.ResultsAll patients were postmenopausal, with a mean age at the time of the intervention of 70.41 years, with no differences between groups. Mean BMI was 23.67 kg/m2, higher in the group with a sensation of vaginal heaviness (p = 0.027). Mean time elapsed between diagnosis and operation was 231.58 days, with no differences between groups. Mean childbirth count was 2.29. The most frequent causes for consultation were urethrorrhagia (33.33%) and a bulging sensation (33.33%). After the intervention, 14 patients (82.35%) were asymptomatic, two (11.76%) had dysuria, and one (5.88%) had urinary urgency. Ten patients had pre-surgical urinary incontinence, which was resolved in nine patients. 17.46% subsequently presented pelvic organ prolapse. In three women there was secondary impairment of sexual activity.ConclusionThe four-vertex technique was effective in resolving symptoms in most patients. However, some patients experienced dysuria, urinary urgency, and pelvic organ prolapse after surgery. Urinary incontinence improved in most patients, but a few required additional treatments with suburethral tape. The study also identified associations between variables and the presence of cystocele, consultation for a bulging sensation, and bleeding from urethral prolapse. Overall, this study sheds light on the challenges and outcomes of surgical treatment for urethral prolapse and provides valuable insights for future research in this area.

Project description:PurposeTo evaluate and compare the efficacy of intermittent needle aspiration and continuous catheter drainage in ultrasound-guided management of liver abscesses.MethodsThis was a prospective, randomised study conducted on 100 patients (88 males and 12 females; age range 22-74 years) with liver abscess(es) and having abscess size more than 5 cm, divided into two groups: Percutaneous needle aspiration (PNA) (n = 50) and percutaneous catheter drainage (PCD) (n = 50). Criteria of exclusion were: rupture of abscess before intervention; prior intervention; uncorrectable coagulopathy; concomitant biliary tract malignancy. In the PNA group, pus was aspirated by an 18-gauge needle using freehand technique and the number of aspirations was limited to two. Failure of abscess size to decline below 50% of the original diameter or of clinical improvement after second aspiration was considered as failure of aspiration. In the PCD group, drainage was done by 12-French catheters using Seldinger technique. Drainage was considered as failure if abscess cavity did not resolve and laparotomy was needed to evacuate the pus cavity.ResultThe success rate in the PNA group was 88% and 92% in the PCD group; however, this difference was statistically not significant, suggesting that both are equally efficacious. The total duration of hospital stay (mean 6.8 days [PNA] vs 10.5 days [PCD]; p value: 0.011) and the average duration between intervention and discharge (5.9 days [PNA] vs 10.2 days [PCD]; p value:0.026) were significantly less in the PNA group. One major complication was seen in our study: peritonitis due to peri-catheter leak in PCD group.ConclusionBoth procedures are equally efficacious in the management of liver abscesses; however in view of less duration of hospital stay, patient safety and comfort, procedure simplicity, and the reduced cost, needle aspiration should be used as the first-line procedure in the treatment of liver abscess (even in abscesses more than 5 cm). Catheter drainage should be reserved for cases that do not respond to a second attempt of aspiration.

Project description:ObjectiveEmerging evidence suggests that chest radiography (CXR) following central venous catheter (CVC) placement is unnecessary when point-of-care ultrasound (POCUS) is used to confirm catheter position and exclude pneumothorax. However, few providers have adopted this practice, and it is unknown what contributing factors may play a role in this lack of adoption, such as ultrasound experience. The objective of this study was to evaluate the diagnostic accuracy of POCUS to confirm CVC position and exclude a pneumothorax after brief education and training of nonexperts.MethodsWe performed a prospective cohort study in a single academic medical center to determine the diagnostic characteristics of a POCUS-guided CVC confirmation protocol after brief training performed by POCUS nonexperts. POCUS nonexperts (emergency medicine senior residents and critical care fellows) independently performed a POCUS-guided CVC confirmation protocol after a 30-minute didactic training. The primary outcome was the diagnostic accuracy of the POCUS-guided CVC confirmation protocol for malposition and pneumothorax detection. Secondary outcomes were efficiency and feasibility of adequate image acquisition, adjudicated by POCUS experts.ResultsTwenty-six POCUS nonexperts collected data on 190 patients in the final analysis. There were five (2.5%) CVC malpositions and six (3%) pneumothoraxes on CXR. The positive likelihood ratios of POCUS for malposition detection and pneumothorax were 12.33 (95% confidence interval [CI] = 3.26 to 46.69) and 3.41 (95% CI = 0.51 to 22.76), respectively. The accuracy of POCUS for pneumothorax detection compared to CXR was 0.93 (95% CI = 0.88 to 0.96) and the sensitivity was 0.17 (95% CI = 0.00 to 0.64). The median (interquartile range) time for CVC confirmation was lower for POCUS (9 minutes [8.5-9.5 minutes]) compared to CXR (29 minutes [1-269 minutes]; Mann-Whitney U, p < 0.01). Adequate protocol image acquisition was achieved in 76% of the patients.ConclusionThirty-minute training of POCUS in nonexperts demonstrates adequate diagnostic accuracy, efficiency, and feasibility of POCUS-guided CVC position confirmation, but not exclusion of pneumothorax.
