Abstract Objectives: Day of surgery cancellations present several workflow challenges that result in delay of care for patients and revenue loss for physicians. This study aimed to further understand same-day pediatric urology surgical cancellations, and the authors assessed identifiable trends for quality improvement over a one-year time period. Methods: Same-day surgical cancellations were prospectively identified at a single tertiary care center, Atrium Health Wake Forest Baptist, from 01 October 2022 to 30 September 2023. Reasons for cancellation were recorded per the parent/legal guardian and categorized as an avoidable or unavoidable cause. Demographic data, surgical rescheduling, and… More >

Abstract Background: Benign prostatic hyperplasia (BPH) is prevalent among aging men. Whether exposure to internet-derived health information is associated with disease awareness and symptom burden at initial diagnosis remains unclear. Methods: We conducted a cross-sectional study of 400 newly diagnosed BPH outpatients. Participants were classified by prior exposure to internet-derived BPH content. BPH awareness and International Prostate Symptom Scores (IPSS) were compared using the Mann-Whitney U test and multivariate linear regression adjusted for age, education, and disposable income. Stratified analyses were performed according to educational attainment, disposable income, and content format. Results: Exposure to internet-derived BPH content… More >

Abstract Background: Congenital nephrogenic diabetes insipidus (CNDI) is most frequently caused by mutations in the AVPR2 gene. Patients exhibit persistent polyuria due to renal insensitivity to antidiuretic hormone. Chronic high urine output predisposes to bladder dysfunction and upper urinary-tract dilatation, notably hydronephrosis. Although pharmacotherapy can partially reduce urine volume, its capacity to reverse established hydronephrosis is limited. Clean intermittent catheterization (CIC), a mainstay in managing neurogenic bladder, warrants investigation regarding its utility in CNDI-associated hydronephrosis.
Case Description: A 9-year-old Chinese boy presented with lifelong polydipsia and polyuria, with a peak 24-h urine output of approximately 7100 mL. Renal ultrasonography… More >

Abstract Background: Robot-assisted partial nephrectomy (RAPN) is standard for cT1 renal masses, but its feasibility in patients on temporary mechanical circulatory support is poorly documented. We report RAPN performed while a patient was simultaneously supported with venous-arterial extracorporeal membrane oxygenation (VA ECMO) and Impella®, as part of a staged plan for left ventricular assist device (LVAD) implantation and eventual heart transplantation. Case Presentation: A 51-year-old man presented with ST-elevation myocardial infarction complicated by cardiogenic shock requiring percutaneous coronary intervention with stenting, dual antiplatelet therapy, and combined VA ECMO–Impella® support. During workup for cardiac transplant, computed tomography (CT) staging… More >

Abstract Background: Penile constriction rings are most used for sexual pleasure and the management of sexual dysfunction. However, they pose a risk of injury and can be challenging to remove when strangulation occurs. Case Description: We present a case of a patient with urinary retention and a strangulation injury from a penile constriction ring present for 19 h before initial presentation. Multiple attempts to remove the penile ring were unsuccessful, and ultimately, operative management was required. Conclusions: We describe an effective technique for the removal of a stainless-steel penile constriction ring using a Stryker 505 power revision More >

Abstract Background: Early detection and timely treatment of urinary tract infections (UTIs) can prevent the aggravation of the inflammatory response following a stroke and enhance the recovery of neurological function. This study aimed to develop a simple scoring system by integrating nutritional and inflammatory markers to predict the occurrence of UTIs in patients with acute stroke. Methods: Reviews of 1011 patients with acute stroke were retrieved. The Geriatric Nutritional Risk Index (GNRI) and systemic inflammation response index (SIRI) were utilized to develop a composite score of nutritional-systemic inflammation response index (G-SIRI). The primary endpoint was the… More >

Abstract Objectives: Kidney stone disease is increasingly prevalent and may be linked to metabolic factors such as insulin resistance, but there is currently no direct evidence connecting estimated glucose disposal rate (eGDR) to kidney stones. This study aimed to investigate the relationship between eGDR and kidney stone prevalence. Methods: We conducted a cross-sectional analysis utilizing data from the National Health and Nutrition Examination Survey (NHANES) from 2007–2018, including 29,753 participants aged 20 years and older. Weighted multivariable logistic regression and nonlinear models were employed to assess the relationship between eGDR and self-reported kidney stone history. Results: Among… More >

Abstract Background: Vesicourethral foreign bodies are frequently encountered in urological emergency departments; however, cases of penetrating injury to the corpus spongiosum penis and bulbous urethra are rare. Case Description: A 64-year-old man presented with difficulty removing a foreign body that he had inserted into his urethra for masturbation. Abdominal computed tomography (CT) revealed a rod-shaped foreign body lodged from the bulbous urethra to the posterior wall of the bladder. Cystoscopy confirmed penetration of the foreign body into the urethral sponge at the bulbous urethra. An attempt was made to remove the foreign body transurethrally, but it was… More >

Abstract Background: Ureteroenteric anastomotic stricture is a common complication after ureteral diversion with radical cystectomy, which leads to hydronephrosis, infection, and chronic renal failure. Although ureteroneocystostomy is reliable, its high degree of invasion often causes great damage and postoperative complications in patients. Therefore, we offer a new endoscopic approach with relatively limited invasion for severe obstructions such as ureteroenteric anastomotic atresia. Case Description: A 65-year-old man underwent radical cystectomy and urinary diversion of orthotopic neobladder and standardized chemotherapy for high-risk non-muscle-invasive bladder cancer. Severe left hydronephrosis was then detected due to ureteroenteric anastomotic atresia. Percutaneous nephrostomy was… More >

Abstract Objectives: Residual Disease after adjuvant chemotherapy for non-seminomatous germ cell tumor (NSGCT) poses a significant clinical challenge and difficulties in tailored management. This study aimed to externally validate the Heidenreich criteria among patients eligible for unilateral post-chemotherapy retroperitoneal lymph node dissection (PC-RPLND) for residual masses of NSGCT. Methods: For validation, these criteria were retrospectively applied in 23 patients undergoing PC-RPLND for residual masses of NSGCTs. In patients qualified for unilateral-modified PC-RPLND according to the Heidenreich criteria but treated with fully bilateral dissection, pathological reports were evaluated to identify teratoma or active cancer cells inside the… More >

Abstract Background: Retained bullet fragments in the genitourinary tract following gunshot wound is rare and require removal. Case Description: We present the case of a retained bullet in the prostate following a gunshot wound to the pelvis, which was endoscopically removed. A urethral catheter and suprapubic tube were placed. The patient then had migration of a second bullet fragment into the prostatic urethra six weeks later, requiring open removal. Conclusions: This case shows that several approaches can be considered to remove retained bullet fragments from the urinary tract. Furthermore, access to the bladder via a suprapubic tube More >
