Hydronephrosis, "distension in varying degrees of pelvis and calyces, accompanied by progressive atrophy of renal parenchyma due to obstruction in urinary flow", is an apparently simple reno-urinary disease, but, in reality, by association of its own characters with those conferred by causative lesions, becomes of a significant complexity. The purpose of this paper is to demonstrate the pluriva...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2015209957 DESCRIPTION Urinary incontinence is a common problem encountered after prostatectomy. After a trial of conservative management, men are generally left with a choice of surgery, drainage or absorbent devices, or a penile compression device. Artificial urin...

INTRODUCTION Affectation of the bladder after open prostatectomy is demonstrated. Decrease in bladder capacity and bladder compliance, detrusor hyper-or hypo-activity and voiding dysfunction are observed. We propose to investigate the effects of robotic surgery on bladder and sphincter function through the comparative study of preoperative and postoperative urodynamic values 3 months after pros...

objective(s): we aimed to study the effect of trimetazidine (tmz) on urethral wound repair. materials and methods: a total of 52 male rats were used; 8 groups were formed: 1-week and 3-week control (c1,c3), sham (s1, s3), oral (ot1, ot3), and intraurethral tmz (iut1, iut3) groups. serum and urine total antioxidant capacity (tac), total oxidant capacity (toc), and 8-hydroxy-deoxy-guanosine (8-oh...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013200805 DESCRIPTION A 38-year-old man with a background history of thin stream void and dysuria for the last 2 years, presented with an acute urinary retention of 2 days. Physical examination revealed a tender and hard mass in the scrotum and a fistulous track near ...

BACKGROUND We produced a novel model of bladder outlet obstruction (BOO) by periurethral injection of hyaluronic acid and compared the cystometric features, postoperative complications, and histopathological changes of that model with that of traditional open surgery. METHODS Forty female Sprague-Dawley rats were divided into three groups. Fifteen rats were subcutaneously injected with 0.2 ml...

AIM To explore the interaction between bladder compliance (BC) and bladder outflow obstruction (BOO) in men with benign prostatic hyperplasia (BPH) using cross-sectional and longitudinal studies. METHODS A total of 181 men with BPH were recruited, and 100 of them were followed for one year. Cystometry was performed in a standing or a sitting position with 30 mL/min infusion. BC was manually c...

To explore information hidden in the electromyographic (EMG) signals of the urethral sphincter that may be of prognostic significance for patients with primary bladder neck obstruction (PBNO), 41 patients with voiding difficulty were divided into four groups: 1) patients with primary bladder neck obstruction (PBNO) with successful (Group 1, n = 14) and 2) unsuccessful (Group 2, n = 8) surgical ...

AIMS We aim at developing a non-invasive method for grading and diagnosing urinary bladder outlet obstruction, based on noise recording with a perineal contact microphone during voiding. We found that the noise production during voiding depends amongst others on the viscoelastic properties of the urethral wall. To further test our method, we need a realistic biophysical model of the male urethr...

Urolithiasis is a disorder in small ruminants that is frequently seen in castrated males. This urinary tract disease most often involves the urethra, especially at sites where narrowing of the urethral diameter occurs, such as in the distal part of the sigmoid flexure or in the vermiform appendage (urethral process). Struvite and apetite are the more common uroliths seen in the regions of North...
