Urinary tract diseases are among the main reasons for consultation in veterinary clinics and hospitals. It affects animals of any age, breed and gender. Among the diseases that affect this system, urolithiasis is the second largest cause of clinical signs compatible with feline urinary tract disease. The term urolithiasis refers to the presence of uroliths in any region of the urinary tract, but it is more commonly seen in the bladder and urethra. Uroliths are classified based on the type of mineral present in their composition, therefore, quantitative and qualitative analyzes are important for a better therapeutic approach...

AIMS: We aimed to investigate the age-associated changes in movement coordination between the urinary bladder and the urethra in rats. METHODS: A total of 17 female Sprague-Dawley rats were used. The rats were divided into young (3 months old) and middle-aged (12-15 months old) groups. In both groups, isovolumetric cystometry and urethral perfusion pressure (UPP) measurements were performed under urethane anesthesia. After the rhythmic bladder contractions stabilized, L-arginine, a nitric oxide (NO) substrate (100 mg/kg), was administered intravenously in both groups...

A 32-year-old woman presents to outpatients 10 days postpartum, with symptoms of an intermittent vaginal lump and urinary incontinence. Vaginal examination revealed no demonstrable prolapse or stress incontinence. A swelling in the bladder was noted during an antenatal scan suggesting a ureterocoele. She was referred for pelvic floor physiotherapy in the first instance. Forty-eight hours later, she represented to casualty with discomforting vaginal lump symptoms and continuous urinary incontinence. At this stage on vaginal inspection, there was an evident dusky lump emerging from the urethra with continuous incontinence...

Studies documenting the application of ultrasonography to depict normal and pathological changes in koalas (Phascolarctos cinereus), especially in the male, are scarce. Sixty-two wild koalas were used in this study to define ultrasonographic protocols and features for the assessment of the male koala reproductive tract. Testis, epididymis and spermatic cord were examined using a hockey stick transducer. The normal koala testis showed a homogeneous echogenicity and an obvious hyper-echoic band corresponding to the tunica albuginea...

The expression of aquaporins (AQPs) in the fetal porcine urinary tract and its relation to gestational age has not been established. Tissue samples from the renal pelvis, ureter, bladder and urethra were obtained from porcine fetuses. Samples were examined by RT-PCR (AQPs 1-11), QPCR (AQPs positive on RT-PCR), and immunohistochemistry. Bladder samples were additionally examined by Western blotting. RNA was extracted from 76 tissue samples obtained from 19 fetuses. Gestational age was 60 (n=11) or 100 days (n=8)...

Delayed ejaculation (DE) is a poorly defined and uncommon form of male sexual dysfunction, characterized by a marked delay in ejaculation or an inability to achieve ejaculation. It is often quite concerning to patients and their partners, and sometimes frustrates couples' attempts to conceive. This article aims to review the pathophysiology of DE and anejaculation (AE), to explore our current understanding of the diagnosis, and to present the treatment options for this condition. Electronic databases were searched from 1966 to October 2017, including PubMed (MEDLINE) and Embase...

Primary mucinous tumors and secondary tumors involving the prostate gland are relatively uncommon, however they have important diagnostic, therapeutic, and prognostic implications. The primary mucinous tumors of the prostate include mucinous (colloid) adenocarcinoma of the prostate, prostatic adenocarcinoma with mucinous features, and mucinous adenocarcinoma of the prostatic urethra (mucin-producing urothelial-type adenocarcinoma of the prostate). Mucinous adenocarcinoma of the prostate is defined as a primary prostatic acinar tumor characterized by the presence of at least 25% of the tumor composed of glands with extraluminal mucin...

Underactive bladder (UAB) or detrusor underactivity (DU) is a common yet still poorly understood urological problem. In addition to true detrusor failure and neuropathy, the inhibitory effects of detrusor contraction by the striated urethral sphincter and the bladder neck through alpha-adrenergic activity may also play a role in the development of UAB or DU. Treatment of UAB or DU aims to reduce the postvoid residual (PVR) urine volume and increase voiding efficiency, either by spontaneous voiding or abdominal straining...

Urethral leiomyoma is a rare benign mesenchymal tumour arising from the smooth muscle of the urethra. It most often appears in females of reproductive age. Approximately 100 cases have been reported to date. The most usual presentation is urinary infection, hematuria or a mass. We report a case of a 42 year old woman who presented with sporadic hematuria, dysuria and dyspareunia. Histopathological studies confirmed urethral leiomyoma.

PURPOSE: To study correlations between sonographic and urodynamic findings after suburethral sling surgery. METHODS: This is a retrospective study on 141 women who had multichannel urodynamic testing and translabial 4D ultrasound after suburethral sling surgery between 2006 and 2016. The sling-pubis gap, i.e., the distance between sling and infero-posterior margin of the pubic symphysis on Valsalva, and urethral motion profile were determined. The urethral motion profile was assessed by calculating the mobility vectors of 6 equidistant points along the length of urethra from bladder neck to external urethral meatus, against the dorsocaudal margin of the symphysis pubis on Valsalva...

BACKGROUND: The prevalence of obesity with aging is escalating alarmingly; and pelvic organ prolapse (POP) and stress urinary incontinence (SUI) are now becoming a growing epidemic among the elderly. Synthetic transvaginal mesh has been employed with increasing popularity in the treatment of POP and is usually highly effective in controlling the principal symptoms of prolapse. However, studies have reported that mesh operations provide fairly unfavorable SUI cure rates. Therefore, additional anti-incontinence surgical strategies are increasingly being scrutinized to achieve better postoperative continence without any significant side-effects for patients with both POP and SUI...

Circumcision is the most common operation with multiple complications. One of these complications is surgical such as urethrocutaneous fistula due to traumatic and ischemic injury during the operation. A 9-month infant with a history of swelling on the ventral aspect of the penile urethra during micturition was circumcised ritually in 3 months of birth and 6 months later was referred to Imam Reza Hospital with giant ventral fistula in the distal of the penis.
