Gardenia fruit has been used in traditional Chinese medicine for thousands of years. A previous study by the present authors indicated that the ethanol extract of gardenia fruits (EEG) primarily contains eight constituents. In the present study, the potential effects of EEG on unilateral ureteral obstruction (UUO)-induced renal interstitial fibrosis were observed in rats. A total of 30 rats were randomly divided into three groups (n=10 each): Sham group, UUO group, and EEG group, which were administered with EEG (200 mg/kg/day) or the same volume of distilled water as a vehicle...

Antonio Macrì
Pelvic exenteration is a radical surgery that can require urinary and faecal diversions. Double-barreled wet colostomy, a viable alternative to the traditional ileal conduit with separate colostomy technique, is not always applicable due to the shortness of an ureter. To overcome this problem, I modified the original technique, replacing the two uretero-colic anastomoses with an ureteroureterostomy and an uretero-colic anastomosis.

We analysed cancer risks in patients with urinary tract stones but some features of the generated results alarmed us about possible surveillance bias, which we describe in this report. We used nationwide Swedish hospital records to identify patients with urinary tract stones (N = 211,718) and cancer registration data for cancer patients for years 1987 to 2012. Standardized incidence ratios (SIRs) for cancer were calculated after the last medical contact for urinary tract stones. All cancers were increased after kidney (SIR 1...

Deep endometriosis is usually defined as endometriosis infiltrating the peritoneum by >5 mm. It sometimes involves the ureter causing hydronephrosis in 5% of cases. The latter is associated with 18% ureteral lesions. Ureteral endometriosis is one of the rare causes of silent Kidney failure. The ureter obstruction can lead to urinary tract obstruction, hydronephrosis and hydroureters. The ureters are usually compressed externally by the endometriotic lesions surrounding it causing extrinsic ureteral endometriosis, and sometimes by pressure from the bulky adenomyotic uterus with paraureteral fibrosis...

Ureterocele, which is a cystic dilatation of the terminal ureter, is usually associated with the upper moiety in a case of the duplex system. Giant hydronephrosis, a rare entity, is usually due to pelviureteric junction obstruction and is usually diagnosed in infants and children. We report a unique case of a unilateral complete duplex system with ureterocele with giant hydronephrosis of the upper moiety in an adult woman presenting as an abdominal lump. To the best of our knowledge, this is the first case of giant hydronephrosis associated with ureterocele in an adult patient...

The differentiated cell types of the epithelial and mesenchymal tissue compartments of the mature ureter of the mouse arise in a precise temporal and spatial sequence from uncommitted precursor cells of the distal ureteric bud epithelium and its surrounding mesenchyme. Previous genetic efforts identified a member of the Hedgehog (HH) family of secreted proteins, Sonic hedgehog (SHH) as a crucial epithelial signal for growth and differentiation of the ureteric mesenchyme. Here, we used conditional loss- and gain-of-function experiments of the unique HH signal transducer Smoothened (SMO) to further characterize the cellular functions and unravel the effector genes of HH signaling in ureter development...

Urinary tract infection (UTI) is a broad term referring to an infection of the kidneys, ureters, bladder and/or urethra. Due to its prevalence, frequent recurrence and rising resistance to antibiotics, UTI has become a challenge in clinical practice. Autosomal dominant polycystic kidney disease (ADPKD) is the most common monogenic disorder of the kidney and is characterized by the growth of fluid-filled cysts in both kidneys. Progressive cystic enlargement, inflammation and interstitial fibrosis result in nephron loss with subsequent decline in kidney function...

PURPOSE: Stone size and location are generally considered the most important factors associated with spontaneous ureter stone passage (SSP). Several parameters related to inflammatory changes have been identified as predictors associated with SSP. Our aim was to investigate the predictive role of neutrophil-to-lymphocyte ratio (NLR) for SSP. MATERIALS AND METHODS: A retrospective review was performed on 131 patients who were referred to the urology outpatient clinic and diagnosed with unilateral ureteral stones at our emergency department between July 2016 and December 2016...

We describe the case of a 45-year-old woman with a clinical history of breast cancer presenting with anuric renal failure, metabolic acidosis and bilateral grade 2-3 hydronephrosis. Following insertion of bilateral ureteral stents, urinary output was 5000 ml in the subsequent 24 hours with frankly bloody urine, after which anuria recurred. A new ultrasound examination showed hydronephrotic kidneys with properly positioned stents, a distended bladder free of clots and a hypo-anechoic, well-demarcated mass enveloping the aorta...

Retrocaval ureter is a rare anomaly in which the ureter passes behind the inferior vena cava due to abnormal embryogenesis. Very few cases have been reported from Africa. Although the anomaly is congenital, patients become symptomatic in the third or fourth decade of life. We reviewed the records of four patients with the diagnosis of retrocaval ureter and managed in our centre between January 2010 and December 2016. Three patients presented with recurrent colicky right flank pain while one was asymptomatic...
