Introduction: Posterior Urethral Valves (PUV) are rare congenital anomalies of the male urinary tract that can lead to urethral obstruction and increased risk of kidney disease. Traditional diagnosis relies on subjective interpretation of imaging techniques. This study aimed to automate and increase accuracy of PUV detection in voiding cystourethrography (VCUG) images using an AI-based pipeline.

Endometriosis is a common condition among women of reproductive age worldwide, with the urinary tract being the second most frequently affected extragenital organ system, particularly the bladder and ureters. Ureteral endometriosis (UE) is relatively rare, often asymptomatic, and can lead to progressive renal function loss if not addressed promptly. Early diagnosis and intervention are essential, requiring a high index of suspicion.

Background: Cardiovascular and renal complications of type 2 diabetes are the main causes of death in diabetic patients. Clinical studies have found that polyethylene glycol loxenatide (PEG-Loxe), a GLP-1 analog widely used to treat type 2 diabetes, boosts renal and cardiac functions in diabetic patients. However, its mechanism of action remains to be elucidated.

Indications and Outcomes of Fetal Cystoscopy for Lower Urinary Tract Obstruction: A Comprehensive Review.

Prenat Diagn

December 2024

Division of Maternal-Fetal Medicine, Department of Maternal and Fetal Medicine, Obstetrics and Gynecology, Miller School of Medicine, University of Miami, Miami, Florida, USA.

Fetal lower urinary tract obstruction (LUTO) encompasses a spectrum of rare congenital anomalies affecting the fetal urinary system, leading to significant morbidity and mortality. This condition, arising from various anatomical anomalies such as posterior urethral valves (PUV), urethral atresia, and cloacal malformations, disrupts normal urine flow, resulting in secondary complications such as pulmonary hypoplasia and renal impairment. Current management strategies, including fetal vesicoamniotic shunting (VAS) and fetal cystoscopy, aim to alleviate obstruction and mitigate associated risks.

Renal artery thrombosis is an uncommon but serious cause of acute kidney injury that can result in permanent loss of function. It is frequently misdiagnosed due to its non-specific appearance, which can mimic renal colic and other more common causes of abdominal pain. There is no agreement on the first-line treatment and no prospective studies comparing thrombolysis, anticoagulation and embolectomy.

A case of redo pyeloplasty using robot-assisted retroperitoneoscopic pyeloplasty (RARP) for failed primary laparoscopic pyeloplasty (LP) for ureteropelvic junction obstruction (UPJO) is reported. A 12-year-old boy had LP elsewhere. He was referred for management of persistent left hydronephrosis, but was managed conservatively due to minimal symptoms and stable radioisotopic renography.

Urinary incontinence is the involuntary loss of urine. It is a prevalent and bothersome condition in females, with subtypes including stress, urge, mixed stress/urge, and overflow. Evaluation begins with a history to identify symptoms of the different subtypes and information about comorbid conditions, incontinence frequency and severity, and effect on quality of life.

At the Scrub Sink: Evaluation of Ureteric Patency During Cystoscopy.

Urogynecology (Phila)

January 2025

From the Medical and Surgical Gynecology Department, Mayo Clinic College of Medicine, Mayo Clinic, Jacksonville, FL.

At the scrub sink, we discussed the best ways to evaluate for ureteric patency during cystoscopy. For decades, surgeons have been using intravenous indigo carmine for evaluating ureteric patency. Ten years ago, a shortage of indigo carmine halted production.

Seminal Vesiculitis: A Rare Cause of Unilateral Ureteric Obstruction.

Cureus

November 2024

Urology, Belfast Health and Social Care Trust, Belfast, GBR.

The seminal vesicles are an accessory structure of the male reproductive system. The most common pathology associated with the seminal vesicles is infective, and patients may present with haematospermia, pain, and subfertility. Patients presenting with unilateral ureteric obstruction secondary to seminal vesiculitis are rare, and there are very few reported cases in the literature.

Lichtenstein repair for giant inguinoscrotal hernia: a retrospective case-control study.

Hernia

December 2024

Department of Hernia and Abdominal Wall Surgery, Beijing Chaoyang Hospital, Capital MedicalUniversity, Beijing, 100043, China.

Purpose: Giant inguinoscrotal hernia (GISH) is a rare condition in high-income regions, and the management presents a significant challenge for surgeons. A retrospective analysis was conducted of a single center's experience in treating GISH by Lichtenstein approach. The objective was to gain insight into the characteristics of GISH and assess the clinical efficacy of the Lichtenstein approach, as well as the degree of improvement in patient quality of life (QoL).

Congenital obstruction of the upper urinary tract is often caused by the pyeloureteral junction syndrome, the lower polar vessel being the most common extrinsic etiology. We report on a case that was successfully treated using the Vascular HITCH, an alternative method with lower morbidity than Anderson and Hynes pyeloplasty considered the gold standard procedure. Our objective is to outline the aforementioned method and illustrate its ease of use and possible efficacy in carefully chosen adult patients.

Kidney fibrosis is the common pathological pathway in progressive chronic kidney disease (CKD), and current treatments are largely ineffective. The C-X-C chemokine receptor 4 (CXCR4) is crucial to fibrosis development. By using neural cell adhesion molecules as scaffolds with binding loops that mimic the shape of shark antibodies, fully humanized single-domain i-bodies have been developed.

Renal Epithelial Complement C3 Expression Affects Kidney Fibrosis Progression.

Int J Mol Sci

November 2024

Institute of Translational Medicine, Semmelweis University, Nagyvárad tér 4, 1089 Budapest, Hungary.

Kidney fibrosis is a hallmark of chronic kidney diseases. Evidence shows that genetic variability and complement component 3 (C3) might influence tubulointerstitial fibrosis. Still, the role of renal C3 production in the epithelial-to-mesenchymal transition (EMT) and genetically determined fibrosis progression remains undiscovered.

Obstructive feline lower urinary tract disease (OFLUTD) is the most common complication of the urinary system, as metabolic and electrolyte changes can alter the functioning of the autonomic nervous system (ANS). The objective of this study was to describe the indices of heart rate variability (HRV) and their correlations with the observed alterations in Systolic Blood Pressure (SBP) and electrocardiographic, biochemical, and haemogasometric indices in cats diagnosed with OFLUTD. Sixty-five male cats up to 10 years of age were divided into two groups.

Urinary tract obstruction (UTO) is a common cause of kidney injury that can result in chronic kidney disease and end-stage renal disease. Heterogeneity in the extent of obstructive renal damage in humans with UTO implies the existence of unknown mechanisms that protect against or accelerate kidney injury. Prior studies show that congenital and acquired UTO initiate a conserved, protective program of renal urothelium remodeling that culminates in expansion of uroplakin (UPK)+ cells to promote renal structural integrity.

Background: Small prostates (volume <30 ml) induce bladder outlet obstruction with pathophysiological changes distinct from those associated with large prostates. Treatment options often include transurethral incision of the prostate (TUIP) or transurethral resection of the prostate (TURP). Existing treatments have issues with high recurrence and complication rates.
