Angiotensin II, type 2 receptor in the development of vesico-ureteric reflux

2001

Objective To investigate if mutation of the angiotensin II (Ang II) receptors AT2 is involved in primary vesico-ureteric reflux (VUR) in humans. Patients and methods Genetic polymorphisms in the AT1 and AT2 receptors was evaluated in 23 patients having the most common congenital urological abnormality, namely primary congenital VUR. The occurrence of the A1166C transition in the AT1 receptor gene and the A-1332G transition in the AT2 receptor gene were evaluated and compared with the incidence in normal controls with no urological abnormalities. Result The distribution of the AT1 receptor genotypes was no different between patients with VUR and healthy controls. Furthermore, 10 of 23 (44%) …

Histological and histochemical changes in the colon mucosa after ureterosigmoidostomy or colonic conduit.

1988

A study was made of 22 patients previously subjected to urinary diversion, 12 with ureterosigmoidostomy and 10 with colon conduit. The histological and histochemical examination of biopsies of intestinal mucosa near to and far from the ureteral orifices showed transformations with considerable inflammatory infiltration, variations in the composition of the acid mucins with a prevalence of sialomucins, lengthening and branching of the glandular crypts, and sometimes dysplasias of the epithelium. These structural modifications are typical of transitional mucosa. Transitional mucosa might reflect an aspecific reaction of the intestinal mucosa or alternatively it might signify a precancerous co…

Renal papillary necrosis is described as an ischemic or chemical lesion at the end of the Malpighi pyramid, which causes the necrosis, with detachment and expulsion of the papilla in the urine. It ...

Antibiotic prophylaxis in antenatal nonrefluxing hydronephrosis, megaureter and ureterocele

2012

Observation is a conservative management option in infants with nonrefluxing hydronephrosis, primary nonrefluxing megaureter and ureterocele diagnosed postnatally following antenatal detection of hydronephrosis. Antibiotic prophylaxis might be a sensible regimen under these circumstances to prevent UTI in this population who are potentially at increased risk. However, studies examining the efficacy of prophylactic antibiotics are sparse in this setting. For each condition, prophylactic policies seem extremely variable, and UTI rates vary widely with comparable rates reported between patients followed on and off antibiotics. Overall, antibiotic prophylaxis seems unnecessary in patients with …

Quality of life in women undergoing urinary diversion for bladder cancer: results of a multicenter study among long-term disease-free survivors

2012

Purpose: Women undergoing radical cystectomy (RC) and urinary diversion for bladder cancer experience substantial limitations in health-related quality of life (HRQOL). However, the level of discomfort caused by different urinary diversion has been never evaluated in long term survivors. The aim of this multicenter study is to evaluate differences in HRQOL among recurrence-free women undergoing cutaneous ureterostomy (CUS), Bricker's ileal conduit (BK-IC) and Orthotopic neobladder VIP (ONB-VIP) in disease-free females treated with radical cystectomy (RC), with long-term follow up (mean 60.1 months; range 36-122 months). Materials and methods: All consecutively treated female patients from t…

Ureteral Stones: Shockwave Lithotripsy or Ureteroscopy, Which is Best?

2021

Background Renal stone disease is common and can cause emergency presentation with acute pain due to ureteric colic. International guidelines have stated the need for a multicentre randomised controlled trial (RCT) to determine whether a non-invasive outpatient (shockwave lithotripsy [SWL]) or surgical (ureteroscopy [URS]) intervention should be the first-line treatment for those needing active intervention. This has implications for shaping clinical pathways. Objective To report a pragmatic multicentre non-inferiority RCT comparing SWL with URS. Design, setting, and participants This trial tested for non-inferiority of up to two sessions of SWL compared with URS as initial treatment for ur…

Endoscopic treatment of intraluminal ureteral suture with holmium laser

2021

Although reconstructive surgery is the most accepted treatment for ureteral injury, there are reports of cases where endourologic treatment led to correct resolution of the problem. We present the case of a female patient aged 72-year-old who was previously underwent sacralcolpopexy because of anterior vaginal compartment prolapse. The patient underwent surgery to remove the mesh, due to the pain she had had since it was placed. A mid-line laparotomy was performed removing completely the mesh. At 48 hours after intervention, the patient started feeling an intense pain in the left renal fossa that was not relieved with anti-inflammatories and morphic drugs. In the diagnostic ureteroscopy, it…

MONITORAGGIO ECOGRAFICO NEL TRATTAMENTO ENDOSCOPICO PER REFLUSSO VESCICO-URETERALE: QUANDO LA CISTOURETROGRAFIA PUO' ESSERE EVITATA
