1. High pressure endoscopic irrigation: impact on renal histology
ABSTRACT Purpose: High intra-renal pressures during flexible ureteroscopy have been associated with adverse renal tissue changes as well as pyelovenous backflow. Our objective was to investigate the effect of various intra-renal pressures on histologic changes and fluid extravasation during simulated ureteroscopy. Materials and Methods: Twenty-four juvenil

2. Positive outcomes of phosphodiesterase type 5 inhibitor on histopathologic and biochemical changes induced by ureteral obstruction
RESUMO OBJETIVOS: Examinamos os efeitos do tadalafil em um dos inibidores da fosfodiesterase tipo 5 (PDE5) em um modelo de rato com obstrução ureteral unilateral parcial e completa (UUO). MÉTODOS: Os ratos foram divididos em cinco grupos: sham (n = 6), obstrução ureteral unilateral parcial (PUUO, n = 6), PUUO com tadalafil (PUUO T; Cialis, 10 mg/72 h,

3. Which is best method for instillation of topical therapy to the upper urinary tract? An in vivo porcine study to evaluate three delivery methods
ABSTRACT Purpose: To compare the staining intensity of the upper urinary tract (UUT) urothelium among three UUT delivery methods in an in vivo porcine model. Materials and methods: A fluorescent dye solution (indigo carmine) was delivered to the UUT via three different methods: antegrade perfusion, vesico-ureteral reflux via in-dwelling ureteric stent and

4. Renal capsule for augmentation cystoplasty in canine model: a favorable biomaterial?
ABSTRACT Purpose: To evaluate effectiveness of canine renal capsule for augmentation cystoplasty. Materials and Methods: Ten adult dogs participated in this study. After induction of anesthesia each animal underwent bed side urodynamic study, bladder capacity and bladder pressure was recorded. Then via mid line incision abdominal cavity was entered, right

5. Sphingosine Kinase 1 urothelial expression is increased in patients with neurogenic detrusor overactivity
Objectives: To evaluate the expression of sphingosine kinase 1 (SPK1) in the bladder wall in patients with neurogenic lower urinary tract dysfunction and its association with clinical, urodynamic and pathological features. Materials and Methods: The expression of SPK1 was studied in bladder wall specimens obtained from cystectomy using immunohistochemistry

6. A new problem in inflammatory bladder diseases: Use of mobile phones!
Purpose Technological developments provide a lot of conveniences to our lives. This issue is one of the risks that arise along with these conveniences. In our study we tried to understand the impact of electromagnetic waves from mobile phones on bladder tissue. Materials and Methods Twenty-one adult male albino rats were divided into three equal groups.

7. Evaluation of the metabolism of glycosaminoglycans in patients with interstitial cystis
Introduction: Painful bladder syndrome/interstitial cystitis (PBS/IC) pathogenesis is not fully known, but evidence shows that glycosaminoglycans (GAG) of bladder urothelium can participate in its genesis. The loss of these compounds facilitates the contact of urine compounds with deeper portions of bladder wall triggering an inflammatory process. We invest

8. Avaliação do metabolismo de glicosaminoglicanos em pacientes portadores de cistite intersticial / Evaluation of the metabolism of glycosaminoglycans in patients with interstitial cystitis
Introduction: interstitial cystitis is a chronic disease of the lower urinary tract whose symptoms are: increased urinary frequency, nocturia, perineal or pelvic pain that worses with bladder filling and improves with urination. The pathogenesis is not fully known, but there is evidence that proteoglycans and glycosaminoglycans lining the bladder urothelium

9. Análise da composição da matriz extracelular das camadas urotelial e muscular da bexiga de mulheres em diferentes idades / Composition of extracellular matrix of urothelial and muscular layer of bladder wall in women at different ages
A complacência da bexiga depende de músculos lisos, fibras colágenas, fibras elásiticas e suas relações. O objetivo deste trabalho é determinar a composição da matriz extracelular em amostras de bexigas normais através de análise bioquímica de colágeno e glicosaminoglicanos em amostras obtidas de mulheres em diferentes grupos de idade, analisand

10. Efeito protetor da L-arginina e L-glutamina no pênis de ratos submetidos à irradiação pélvica / Protective effects of L-arginine and L-glutamine on the penis of rats submitted to pelvic radiation
We investigated whether arginine and glutamine protect penile tissues against radiation-induced damage. Groups of Wistar rats were treated with: no intervention; pelvic radiation, and sacrifice 7 (RAD7) or 15 (RAD15) days later; and pelvic radiation, daily supplementation with L-arginine (A) or L-glutamine (G), and sacrifice 7 (RAD7+A, RAD7+G) or 15 (RAD15+A

11. Investigations into the presence of functional ß1, ß2 and ß3-adrenoceptors in urothelium and detrusor of human bladder
Purpose: We investigated the presence of functional ß1, ß2 and ß3-adrenoceptor in urothelium and detrusor muscle of human bladder through in vitro pharmacology of selective ß3 adrenoceptor agonist solabegron. Materials and Methods: Expression of these adrenoceptors in surgically separated human urothelium and detrusor muscle were investigated using RT-PC

12. Histopathological evaluation of urethroplasty with dorsal buccal mucosa: an experimental study in rabbits
PURPOSE: Buccal mucosa is a widely accepted tissue for urethroplasty. The exact healing and tissue integration process, mainly the histological characteristics of dorsal buccal mucosa graft urethroplasty when used dorsally to reconstruct the urethral plate has not previously been assessed, and thus we developed an experimental model to address this question.
