Case report of a patient who, while being under study due to total urinary incontinence and multiple urinary tract infections, interoccurs with urosepsis due to a forgotten and encrusted double-J stent. An open surgery is performed with two surgical approaches, suprapubic and minimal lumbotomy, in which a nephrectomy of the atrophic kidney, a resection of the urether with a calcified double-J in its interior and a cystolithotomy were conducted with the resulting favorable resolution of the pathology.

Treatment of biliary atresia is a major challenge in pediatric surgery. Early diagnosis and availability of Kasai procedure with its modern modifications improve outcome of biliary atresia treatment. But Kasai procedure does not fully restore anatomical integrity of biliary tract, because Oddi sphincter is not included in reconstructed system. Constant reflux of intestinal content into the biliary tree is a cause of recurrent cholangitis and change in biliary epithelium that, which is a predisposing factor for cholangiocarcinoma...

PURPOSE: Kidney stone disease in children is a rare pathology, with a low incidence in Spain (1/4,500 hospitalized children). The spontaneous expulsion rate is about 34-47% which means that more of 50% of children need active treatment. Paediatric patients forming urinary stones have a high risk of recurrence, therefore, a standard diagnosis and treatment are needed. We present our experience in urolithiasis treatment in children. MATERIALS AND METHODS: We reviewed retrospectively all the patients ≤ 16 years hospitalized in our hospital with urolithiasis diagnosis from 2000 to 2013, citing treatment modality, stone-free rates and complications...

Surgical treatment of invasive carcinoma of the bladder in males includes total cystectomy removal of the prostate, seminal vesicles, and the distal parts of the urethers and the pelvic lymph node dissection as well. At this moment it is not possible to recommend a particular type of urinary diversion, but today in clinical practice commonly used derivative are ileal orthotopic neobladder as the continent one and ileal conduit as non-continent urinary diversion. Continent urinary diversion after radical cystectomy are the result of the application of technological innovation in surgery, but also knowledge, imagination and skill of well trained urologist...

INTRODUCTION: Some cases of secondary adenocarcinoma developing in the replaced bowel segment of urinary diversions have been reported so far. Secondary adenocarcinoma develops 20 years after surgery in about 0.5% of those in whom an ileal segment is used. There have been several reports in the literature describing extensions of transitional cell carcinoma (TCC) from the distal urether into an ileal conduit. Histology of loop tumor in 50% was TCC. The site of tumors in the majority of cases is the area at the uretheral orifices or the stoma...

Systemic infusions of ANG II rapidly induce large, dynamic increases in the permeability of the glomerular filtration barrier (GFB) in rats. After binding to its receptor(s), ANG II generates reactive oxygen species (ROS) and produces Ca²⁺ influx into cells, leading to activation of a plethora of signaling cascades, including, e.g., calcineurin and small GTPases, such as Rac-1 and RhoA. In the present study we sought to interact with some of these cascades to test potential novel antiproteinuric agents. In anesthetized Wistar rats, the left urether was cannulated for urine collection, and blood access was achieved...

Because both androgens and estrogens have been implicated in penile morphogenesis, we evaluated penile morphology in transgenic mice with known imbalance of androgen and estrogen signaling using scanning electron microscopy (SEM), histology, and immunohistochemistry of androgen and estrogen receptors α/β. Penises of adult wild-type, estrogen receptor-α knockout (αERKO), estrogen receptor-β knockout (βERKO), aromatase knockout (Arom-KO), and aromatase overexpression (Arom+) mice were evaluated, as well as adult mice treated with diethylstilbestrol (DES) from birth to day 10...

UNLABELLED: WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: The incidence of specific aetiologies of urethral stricture disease has been reported from a variety of series throughout the world. Most reported urethral stricture series are from single institutions or from a specific region of the world. We provide a multi-centred series to compare aetiologic incidence between differing regional populations. OBJECTIVE: To better understand distinct regional patterns in urethral stricture aetiology and location among distinct regional populations...

The closed injuries of the lower urinary tract: problems of the X-ray diagnostics. Results of X-ray investigation were analyzed in 54 patients with urinary bladder trauma and 23 patients with urethral injuries. There were no false conclusions during urography in 23 patients with urethral injuries. In one patient urography was carried out in late terms due to the underestimation of urether trauma by the time of admission to the hospital. Cystography was carried out in 38 out of 54 patients to exclude bladder trauma...

BACKGROUND: Despite antiretroviral therapy (ART), incident human immunodeficiency virus (HIV) continues to rise, and sexually transmitted infections (STI) are well known for their part in HIV transmission. National guidelines recommend routine STI screening in HIV-positive individuals, but despite this, reported uptake remains low. METHODS: We implemented a nurse-led self-screening program for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) in asymptomatic HIV patients...

BACKGROUND: Nowadays translational medicine is acquiring a more and more important role in connecting laboratory experimental results on human tissues to clinical findings and drug employment. We want to underline the importance of in vitro studies, which have been extensively performed on animal organs, but few studies have been performed on human tissues. Nevertheless, a more accurate result when compared to the in vivo use of drugs can be given only by testing the very same human tissues in a lab...

INTRODUCTION: Application of the metallic stents in the interventional uroradioligy is the result of continous development of the new generation methods percutaneous nephrostomy (PCN), ballon catheter dilatation (BCD), methal and covered stent application. Application of metal stents in the renal canal system was attempted in order to eliminate BCD and PCN--related limitations as well as poor therapeutic results of these methods in a number of etiopathogenic groups of urinary stasis. Years--long application of interventional uroradiology methods, until the development of metallic stengts had shown the following therapeutics facts: PCN is incapable to resolve the caus of urinary obstruction...

The present study was performed to investigate the effects of systemic atrial natriuretic peptide (ANP) infusion on the glomerular permeability to macromolecules in rats. In anesthetized Wistar rats (250-280 g), the left urether was cannulated for urine collection while simultaneously blood access was achieved. Rats were continuously infused intravenously with ANP [30 ng·kg(-1)·min(-1) (Lo-ANP; n=8) or 800 ng·kg(-1)·min(-1) (Hi-ANP; n=10)] or 0.9% NaCl (SHAM; n=16), respectively, and with polydisperse FITC-Ficoll-70/400 (molecular radius 13-90 Å) and 51Cr-EDTA for 2 h...

Chyluria is an uncommon condition characterized by lymphatic fluid excretion into the urinary tract. Most common causes of chyluria are infections by parasites e.g. filariasis, echinococcosis, or cysticercosis. Nonparasitic chyluria is a very rare condition and possible etiologies include granulomatous disease (e.g. tuberculosis, leprosy, and fungal infection), malignomes, inherited and acquired malformation (posttraumatic), pregnancy, or aortic aneurysm. We present a case of a 73-year-old man, born and raised in Taiwan, but living in Austria for the past 5 years...

Urothelial tumours which infiltrate the vesical muscle or more superficial tumours which resist localised treatment (resection+/-BCG or mytomicin C) should be considered for excision. Excision is successful in female cystectomy and in male radical cystoprostatectomy. For local tumours of the bladder (<T3), this treatment allows for a specific survival of 5 years at 90 % to be obtained. After the excision of the bladder, several types of urinary diversions may be proposed. The replacement neo-bladder by ilioplasty (orthotopic replacement) should be chosen when possible (conservation of the urether)...

BACKGROUND: Urethral hypermobility is one of the theories developed to explain stress urinary incontinence. Traumatic damage to urethral supports during vaginal childbirth may be an important contributor. AIMS: To establish a methodology to study urethral mobility, to determine the urethral motion profile in a cohort of young nulliparous women, and to determine changes in urethral mobility after childbirth. METHODS: Ultrasound volume datasets of 44 nulligravidae and the 4D antepartum and post-partum datasets of 73 nulliparous women were assessed using post-processing software...
