Objective: To determine if a discrepancy exists in the number and type of cases logged between female and male urology residents.

Materials And Methods: ACGME case log data from 13 urology residency programs was collected from 2007 to 2020. The number and type of cases for each resident were recorded and correlated with resident gender and year of graduation.

Background: Given that patients with morbid obesity are predisposed to frailty, we sought to determine whether the 5-Factor Modified Frailty Index (mFI-5) predicts postoperative complications following surgery for adult-acquired buried penis, and secondarily, to compare the mFI-5 to body mass index (BMI) and American Society of Anesthesiologists (ASA) status as preoperative risk stratification measures.

Methods: We included all patients who underwent surgical management for adult-acquired buried penis at an academic Level I trauma center between 2015 and 2023. A manual chart review was performed to collect data on patient demographics, modified frailty index variables, intraoperative data, postoperative outcomes, and complications.

Objective: To evaluate longitudinal trends in surgical case volume among junior urology residents. There is growing perception that urology residents are not prepared for independent practice, which may be linked to decreased exposure to major cases early in residency.

Methods: Retrospective review of deidentified case logs from urology residency graduates from 12 academic medical centers in the United States from 2010 to 2017.

Background: Adult acquired buried penis (AABP) is a complex condition often necessitating surgical intervention. This study sought to examine the validity of the Wisconsin Classification System (WCS) in guiding the surgical management of AABP. In addition, the authors aimed to identify which factors contribute to postoperative complications and persistent symptoms following AABP repair.

Purpose: A minimum number of index procedures is required for graduation. Without thresholds for surgical technique, it is unclear if robotic and open learning is balanced. We assessed the distribution of robotic and open surgeries performed by residents upon graduation.

Left renal vein transposition is often the preferred treatment of nutcracker syndrome. However, pain returns in some patients despite surgery. One solution to this problem is renal autotransplantation.

Our objective was to seek correlations between the type, volume, and duration of surgical work performed, surgeon habits and characteristics, and the prevalence of neck and back musculoskeletal complaint and intervention across career from training to retirement. An anonymous web-based multinational survey of urologists was conducted. The primary outcome measured was pain.

Penile amputation is a rare injury with significant posttraumatic ramifications. We present a case of successful immediate replantation after traumatic penile avulsion in a 52-year-old male patient. The patient reported his penis was caught in machinery during a boating accident, and avulsed at the level of the pubis.

Background: Adult acquired buried penis syndrome may be associated with an inability to void, sexual dysfunction, and recurrent infection. Previously published classification systems rely on intraoperative findings, such as penile skin quality.

Objectives: The purpose of this study was to evaluate outcomes after adult acquired buried penis repair and to develop a classification system based on preoperative assessment.

Loin Pain Hematuria Syndrome (LPHS) remains a rare disease but has a significant impact on those affected by it. Patients diagnosed with LPHS experience severe, constant or intermittent flank pain that radiates to the groin and may be exacerbated even by a gentle touch. These patients often require significant narcotic regimens for pain control and are unable to maintain a functional lifestyle.

We present a report on use of a web-based electronic patient-reported outcome measures (ePROMs) system to support decision-making for a patient with an osteoarthritic knee. After being placed on a waiting list for knee arthroplasty, the use of preoperative PROMs allowed the patient and surgical team to review ongoing disability, and, as a result, alter the management plan by deferring surgery. Ongoing clinical review and symptom management has been centred on ePROMs and has been tailored to the specific needs of the individual.

Current government policy aims to deliver high quality healthcare by recording accurate data at the point of giving care, storing it efficiently and displaying it in a format, which is easily interpreted by healthcare professionals and patients. Few published reports describe the benefits of collecting and reporting such data from the point of view of the patient. We report the case of a 62-year-old lorry driver who used a web-based system to track patient reported outcome measures (PROMs) following an acute knee injury to full recovery over a 24-month period.

This article reviews the current concepts, recommendations, and principles of fertility preservation in men with cancer. Obstacles to sperm banking are addressed, as well as future directions for fertility-preserving technologies. All cancer therapies--chemotherapy, radiation, and surgery--are potential threats to a man's reproductive potential.

Background: The cause of recently reported pseudotumor formation in patients with metal-on-metal hip replacements is unknown. It has been postulated that there is an association between elevated levels of serum metal ions and pseudotumor formation. The primary purpose of this study was to assess the prevalence of pseudotumor formation in asymptomatic patients with a metal-on-metal total hip replacement after a minimum duration of follow-up of two years.

Background: While the primary objective of joint arthroplasty is to improve patient quality of life, pain, and function, younger active patients often demand a return to higher function that includes sporting activity. Knowledge of rates and predictors of return to sports will help inform expectations in patients anticipating return to sports after joint arthroplasty.

Questions/purposes: We measured the rate of sports participation at 1 year using the UCLA activity score and explored 11 variables, including choice of procedure/prosthesis, that might predict return to a high level of sporting activity, when controlling for potential confounding variables.

Trauma literature regarding management of genitalia trauma affecting future fertility and gonadal function in the face of coexisting life-threatening injuries is underdeveloped. We present a unique case that necessitated integrative management of a 24-year-old male who became entangled within the blades of a manure spreader and presented with life-threatening trauma in addition to severe genital trauma, including penile degloving, bilateral testicular avulsion and bilateral spermatic cord laceration. During the initial stabilization and surgical management, urology and plastic surgery were consulted to assess the urogenital injuries.
