Early vs delayed insertion of penile prosthesis in patients with refractory priapism: a systematic review and meta-analysis.

INTRODUCTION: Refractory priapism, characterized by persistent and prolonged painful erections despite initial treatment maneuvers, can significantly impair erectile function secondary to ischemia-induced corporal tissue fibrosis. These patients will likely require subsequent penile prosthesis (PP) surgery to regain sexual activity, yet consensus regarding the optimal timing of implantation remains lacking. OBJECTIVES: To evaluate and compare the clinical outcomes associated with early vs delayed PP implantation in individuals with priapism-induced erectile dysfunction (ED). METHODS: We included studies that focused on refractory priapism leading to ED and its management with PP implantation. We assessed cohort study bias with a risk-of-bias tool and case series bias with the modified Newcastle-Ottawa Scale. Pooled odds ratios (ORs) were calculated by a fixed-effect model. RESULTS: We included 9 studies, comprising 4 cohort studies and 5 case series, involving a total of 278 patients. Total complications were higher in the delayed group (OR, 4.16; 95% CI, 2.77-6.26). Fibrosis was significantly more pronounced in the delayed group (OR, 118.18; 95% CI, 20.06-696.32). The odds of erosion, infections, and penile injury did not show statistically significant differences between the groups (OR, 2.52 [95% CI, 0.67-9.49], 0.89 [0.38-2.10], 1.83 [0.79-4.26], respectively). Patients' satisfaction resulted in a pooled OR of 0.15 (95% CI, 0.04-0.49) in favor of the early PP insertion group. CONCLUSION: The results from this study favor an early approach to ED (within 30 days) following ischemic priapism. However, it is important to consider patients' preferences, values, and psychological factors to make an informed decision.

Isolated Trapezoid Fracture in Adolescent Goalkeepers: A Scoping Review of the Literature and a Report of Two Cases.

Purpose: Isolated trapezoid fractures are rare injuries, particularly among adolescents, constituting only 0.4% of all carpal bone fractures. This study aims to present two cases of isolated trapezoid fracture in adolescent goalkeepers and a scoping review of the literature to provide guidelines for the management of this injury. Methods: Following PRISMA-ScR guidelines, a scoping review of reported cases was conducted. Two hundred and twenty articles were found using PubMed and Google Scholar. After full-text review, a total of 30 cases from 22 articles along with our 2 cases were analyzed based on demographics, injury mechanism, method/timing of diagnosis, prognosis, and time to recovery. Results: Thirty-two reported cases of trapezoid fractures with a mean age of 26.7 years (75% male) were found, with pain as the most common presenting symptom. A majority (78%) had initial negative findings on radiography, and the diagnosis was primarily established through computed tomography (59%; n = 19) or magnetic resonance imaging (50%; n = 16). There was a substantial delay in diagnosis (mean 26 days), primarily because computed tomography/magnetic resonance imaging was frequently ordered late. The majority of cases (78%) were managed conservatively, with immobilization periods ranging from 4 to 12 weeks. The average duration for full recovery was 4.5 months, with operative management taking 7.3 months and conservative management taking 3.5 months. Conclusion: Trapezoid fractures, though rare, are often not promptly diagnosed on initial plain radiographs, leading to a potential underreporting of cases. Because of the risk of complications associated with this type of injury, clinicians should maintain a high level of vigilance and consider trapezoid fracture as a possible differential diagnosis when presented with carpal pain, swelling, or limited movement, particularly after axial load incidents. Further research and guidelines are needed to enhance our understanding and management of this uncommon injury in the future. Type of study/level of evidence: Differential diagnosis/symptom prevalence IIIb.

The role of Rezum in the management of refractory urinary retention due to benign prostate hyperplasia: A literature review.

Background: Benign prostatic hyperplasia is the most common cause of urinary retention in men (BPH). The gold standard surgical treatment is transurethral resection of the prostate (TURP). However, due to the morbidity and mortality associated with TURP, more minimally invasive treatments, such as vaporizing the prostate with the Rezum system, have been introduced. We investigated the efficacy of Rezum in the treatment of refractory urinary retention due to BPH in this review. Methodology and materials: To conduct this review, the Cochrane methodology for systematic reviews was used. All studies that used Rezum to treat catheter-dependent patients with enlarged prostates were included. The literature search showed 111 studies, 84 of which were excluded due to non-relevance based on titles and 18 due to lack of relevance based on abstract review. Full manuscripts were reviewed in nine studies, three of which were excluded because they did not meet the inclusion criteria. Results: This review included 301 patients in total. The rate of a successful trial of voiding post Rezum therapy was 85%. The complication rated between 3.8 and 4.3% all of which were mild and self-limited. As there was no major complication of Rezum (clavien dindo >2), the procedure-related morbidity is negligible. Conclusion: In this review, Rezum was found to be an efficacious and safe alternative in the treatment of refractory retention with mild complications and minimal morbidity.

Congenital Methemoglobinemia in a 33-Year-Old Patient: A Case Report on a Rare Presentation and a Review of the Literature.

Cyanosis and dyspnea are common complaints in adults and have broad differential diagnoses, of which rare ones such as congenital methemoglobinemia should always be considered in the differential diagnosis. Methemoglobinemia might be acquired or congenital. Patients' symptoms vary from severe shortness of breath, mental status changes, and cyanosis to none. The diagnosis of congenital methemoglobinemia is challenging and requires high index of suspension, especially in older patients. In addition, when diagnosed the treatment of congenital methemoglobinemia is oral ascorbic acid which is readily available. We present a rare case of a 33-year-old lady, who had a long history of recurrent episodes of cyanosis, headache, and fatigue. After excluding cardiopulmonary causes, methemoglobin levels were measured and found to be high, and the chart review revealed high levels of methemoglobin in all her previous episodes, without exposure to any offending agent. This raised the concern of a late diagnosis of congenital methemoglobinemia. The patient was treated with a high dose of ascorbic acid resulting in resolution of the symptoms. Congenital methemoglobinemia is a rare diagnosis that needs a high index of suspicion, especially in adults. A thorough history, physical examination, and multiple laboratory tests are needed to confirm the diagnosis and rule out other causes.

Memokath for treating ureteric stricture post cryoablation of renal mass: A case report of rare complication and proposed alternative management.

The use of cryoablation in the management of small renal masses is widely acceptable. Although rare but ureteral injury during the procedure with subsequent stricture formation can result in devastating effects on renal function. On the other hand, the management of such strictures requires reconstructive surgery as gold standard. Unfortunately, in some cases the reconstructive surgery might not be feasible, and the treatment usually is ureteral stent insertion that need to be changed regularly. Here we present a case of a 53-year-old gentleman who developed an upper ureteric iatrogenic stricture post cryoablation in which the reconstructive surgery was not feasible due to high procedural risk. We used metallic ureteral stent (Memokath) instead of regular ureteral double J stent. We found that if the reconstructive surgery is not possible the usage of Memokath in treating iatrogenic ureteral strictures is associated with better quality of life, lower costs and a similar functional outcome when compared to ureteral double J stent that needs regular frequent changes.

Salvage minimally invasive robotic and laparoscopic pyeloplasty in adults: a systematic review.

Introduction: A UPJO is a blockage of the ureter that affects urine flow. UPJO is mainly treated by an open approach, however, in recent years minimally invasive techniques are taking place. These techniques include robotic and laparoscopic pyeloplasty. Some patients require a redo after a primary intervention. A systematic review was conducted through the examinations of the efficacy and safety of a robotic redo pyeloplasty in adult patients from previous literature reviews. Methods: A literature search was made through PubMed. A selection process was done based on our eligibility criteria. The data were represented numerically, listed on tables and analyzed cumulatively using Microsoft Excel. Results: Twenty studies were included in this review, of which nine were studies on robotic outcomes () (157 patients), 10 on laparoscopic (210 patients), and one review by Zhang et al., focused on both types of surgeries. Two papers (24 patients) from the robotic studies and one paper (21 patients) from the laparoscopic studies were excluded from the intra and post-operative characteristics because not enough data were available and were only included for the success and complication rates. The success rate for the robotic studies was 88.5% while the laparoscopic studies had a success rate of 91%. However, the robotic studies had a complication rate of (11.8%) while the laparoscopic studies had a complication rate of (15.9%). Conversion surgery was required in one patient undergoing laparoscopic surgery. Conclusion: The minimally invasive methods are becoming more viable in adult patients with rUPJO, considering its effectiveness and fast recovery. This can lead to a new era of robotic assisted surgeries to becoming the gold standard.Abbreviations: Systematic review: Redo robotic and laparoscopic pyeloplasty in adults; UPJO = Ureteropelvic junction obstruction; rUPJO = redo ureteropelvic junction obstruction.

Urology Residents' Perspectives on the In-House On-Call Systems: A Study in an Accredited Academic Center.

INTRODUCTION: Medical education and training are crucial in maintaining patients' safety and improving patient care quality. Multiple studies have evaluated the effects of restrictive policies on the resident's quality of life and education. Due to the compiling data and the fact that these trials evaluated programs with a substantial number of residents, it remains uncertain whether these conclusions can be extended to urology programs with a small number of residents. Multiple on-call systems have been adopted in residency programs across the world. This study evaluated the residents' quality of life, clinical experience, and education upon transitioning from 24-hour to 12-hour in-house on-call systems. METHODS AND MATERIALS: In this observational and questionnaire-based study, the effect of the transition from 24-hour to 12-hour in-house on-call systems was compared in terms of the resident's quality of life and education, surgical case volume, and working hours' rules compliance. Quality of life and education: We adopted a validated survey based on a 5-point Likert scale to assess the residents' perception of the transition to a 12-hour on-call system on their quality of life and education. Surgical case volume: We extracted the number of cases the residents operated on from the operating theater database at our institution. Working hours: compliance and violations: The weekly working hours, compliance, and violations per ACGME-I rules were collected from the MedHub platform. RESULTS: Quality of life and education: Residents rated the 12-hour on-call system superior in terms of quality of life, education, and surgical case volume. Surgical case volume: There was a 45% increment in the surgical case volume (p = 0.04) with the 12-hour on-call system. Working hours: compliance and violations There was no significant difference in the mean weekly working hours (p = 0.1). However, the total number of duty hours violations decreased in the 12-hour on-call system. CONCLUSION: The 12-hour system is a better alternative to the 24-hour system in terms of the resident's quality of life, education, surgical case volume, and compliance with duty hour rules.

Metachronous bilateral spontaneous spermatic vein thrombosis: A rare cause of orchialgia.

Scrotal pain and swelling are common presentation, the prompt evaluation and diagnosis is needed due to wide range of causes, uncommon causes of orchialgia should be kept in mind whenever there is no clear diagnosis. Spermatic vein thrombosis usually presents with orchialgia along with episodes of acute exacerbation of pain. The diagnosis is challenging and need high index of suspension and detailed radiological evaluation. We present a case of metachronous bilateral unprovoked spermatic vein thrombosis treated conservatively with anticoagulation with good response and resolution of symptoms.

Squamous cell papilloma a rare urinary bladder tumor, case report and operative video.

Bladder noninvasive squamous lesions are usually rare; here, we are presenting a case of 39 years old male patient with a benign squamous cell papilloma. The tumor grossly presented as cauliflower mass mimicking squamous cell carcinoma, while histologically, the tumor showed extensive keratinization at its surface and showed no nuclear atypia or stromal invasion. This tumor is benign and extremely rare. In this manuscript, we summarized a case of Squamous cell papilloma of the bladder with the first operative video for the transurethral resection of squamous cell papilloma with percutaneous management of associated urinary bladder stones.

Could Guillain-Barré syndrome be triggered by COVID-19 vaccination?

Due to SARS-COV-2 (COVID-19) pandemic and its catastrophic impact on society, the FDA granted emergency use authorization for some vaccines. Possible rare side effects could not have been observed in this relatively short period. We are reporting an elderly lady with multiple comorbidities who presented with progressive lower limb weakness that started seven days after receiving the first dose of the COVID-19 vaccine. The electrodiagnostic study showed demyelinating polyneuropathy with secondary axonal degeneration consistent with Guillain-Barré syndrome. We ruled out other possible causes for GBS, suggesting a postvaccine nature for her presentation. The patient received intravenous immunoglobulin (IVIG) for five days and gradually improved, which supports our initial diagnosis.

The role of red blood cell exchange in sickle cell disease in patient with COVID-19 infection and pulmonary infiltrates.

Due to the overlap between ACS and COVID-19 pneumonia, we recommend close monitoring for those patients and offering them RBC exchange early in the course of the disease to avoid clinical deterioration.

Iron Overload in a Patient with Non-Transfusion-Dependent Hemoglobin H Disease and Borderline Serum Ferritin: Can We Rely on Serum Ferritin for Monitoring in This Group of Patients?

Secondary iron overload is a common complication in the context of hematological diseases, as iron accumulates due to different mechanisms including chronic transfusion, increased gastrointestinal absorption, chronic hemolysis and underlying genetic defects leading to an increase in gastrointestinal absorption of iron. Since the body does not have a mechanism to excrete excess iron, it gets deposited in the heart, endocrine organs, and the liver with the latest being affected less commonly than in primary iron overload disorders like hemochromatosis. Patients with hemoglobin H disease, which is a type of α-thalassemia, are usually transfusion independent, except in occasions where an external stressful factor leads to a drop in hemoglobin and necessitates blood transfusion. Despite this, secondary iron overload is commonly encountered in these patients due to increased gastrointestinal absorption of iron. To avoid the complications associated with iron overload, these patients are usually monitored with serum ferritin, which is an inexpensive widely available method to monitor iron overload. MRI of the liver (Ferriscan) is a more sensitive and specific method to monitor these patients and avoid the long-lasting and sometimes irreversible effect of secondary iron overload. Here we present an interesting case of a patient with hemoglobin H disease, who was monitored with serum ferritin. She had a serum ferritin level considered as a borderline risk for morbidities secondary to iron overload, and an MRI of her liver (Ferriscan) showed significant iron deposition in the liver associated with increased risk of complications secondary to iron overload.
