1. Urethral monopolar cauterization: alternative infravesical obstruction model in male rats
SUMMARY OBJECTIVE: We aimed to determine which method gives the most consistent results between urethral monopolar cauterization and standard urethral partial ligation methods for the urethral obstruction model. METHODS: Thirty male rats were randomly divided into control, partial ligation, and monopolar cauterization groups. Six weeks after experimental p

2. Co-administration of sodium hydrosulfide and tadalafil modulates hypoxia and oxidative stress on bladder dysfunction in a rat model of bladder outlet obstruction
ABSTRACT Purpose: This study aimed to assess the possible healing effect of combination treatment with a hydrogen sulfide (H2S) donor, sodium hydrosulfide (NaHS) plus tadalafil on partial bladder outlet obstruction (PBOO)-induced bladder dysfunction. Materials and Methods: A total of 75 male Sprague-Dawley rats aged 10-wk and 300-350g were divided into fiv

3. Bladder function in children with posterior urethral valves: impact of antenatal versus postnatal diagnosis
ABSTRACT Purpose: Posterior urethral valves (PUVs) are the most common cause of congenital bladder obstruction in boys. Our aim was to assess the impact of early diagnosis and fulguration of PUVs on bladder function and compare their functional and urodynamic outcome with children who underwent delayed intervention. Materials and Methods: We retrospectivel

4. Does successful urethral calibration rule out significant female urethral stenosis? confronting the confounder- an outcome analysis of successfully treated female urethral strictures
ABSTRACT Objective: The diagnosis and treatment of female urethral stricture disease (FUSD) are practiced variably due to the scarcity of data on evaluation, variable definitions, and lack of long-term surgical outcomes. FUSD is difficult to rule out solely on the basis of a successful calibration with 14F catheter. In this study, we have tried to character

6. A new Surgical Technique: Transvesical Prostate Resection
ABSTRACT Objectives: Surgical treatment is indicated in patients where medical therapy fails to prove beneficial or in patients who develop complications related with bladder outlet obstruction. In our study, we developed a new surgical technique which can be defined as Transvesical Resection of Prostate (TVRP) without using the urethra. This method was pre

7. Fluorofenidone inhibits apoptosis of renal tubular epithelial cells in rats with renal interstitial fibrosis
This study aimed to investigate the mechanism of fluorofenidone (AKF-PD) in treating renal interstitial fibrosis in rats with unilateral urinary obstruction (UUO). Thirty-two male Sprague-Dawley rats were randomly divided into sham, UUO, UUO + enalapril, and UUO + AKF-PD groups. All rats, except sham, underwent left urethral obstruction surgery to establish

8. Correlation of tools for objective evaluation of infravesical obstruction of men with lower urinary tract symptoms
ABSTRACT Purpose To identify how the most frequently used parameters in daily clinical practice diagnosing bladder outlet obstruction (BOO) due to benign prostate hyperplasia (BPH) correlate to each other. Materials and methods The study included 452 patients with lower urinary tract symptoms (LUTS) of the UNICAMP urology outpatient clinic of LUTS. Inclu

9. The protective arm of the renin -angiotensin system may counteract the intense inflammatory process in fetuses with posterior urethral valves
Resumo Objetivo: A válvula de uretra posterior é a obstrução do trato urinário inferior mais comum em crianças do sexo masculino. Uma alta porcentagem de pacientes com válvula de uretra posterior evolui para doença renal em estágio final. Estudos anteriores mostraram que citocinas, quimiocinas e componentes do sistema renina-angiotensina contribuem

10. Type II retrocaval ureter causing hydronephrosis in a cat: case report
RESUMO O ureter retrocava (UR) é originado por uma falha na formação embriológica da veia cava caudal (VCC), que leva ao aprisionamento do ureter dorsal à VCC. Na maioria dos casos, não há impacto clínico; entretanto, essa anomalia pode causar hidronefrose. Relata-se um raro caso de UR tipo II sintomático em um felino, tratado com nefroureterectomia

11. Implantação de stent autoexpansível para tratamento de estenose uretral em cão: relato de caso
RESUMO O stent endovascular autoexpansível pode ser utilizado como forma de tratamento para estenose uretral em cães. O stent de nitinol é composto por uma liga de níquel e titânio que permite mudanças em suas estruturas sob a influência da temperatura corporal e tem excelente biocompatibilidade na uretra canina. Este estudo relata o caso de um cão,

12. An unusual presentation of urethral duplication presenting with chronic bladder retention, left scrotal transposition and left renal agenesis
ABSTRACT Introduction and objective Urethral duplication is a rare congenital anomaly, with roughly 200 cases reported in the literature (1). It is more frequent in males, with few cases reported in females. The clinical presentation differs according to the anatomical variant present. The duplication most commonly occurs in the sagittal plane with one uret
