The distribution and density of tyrosine hydroxylase (TH)-immunoreactive nerves in the cat urinary bladder and proximal urethra were similar to those of glyoxylic acid fluorescent nerves. Both TH-immunoreactive and fluorescent nerve fibres markedly decreased after 6-hydroxydopamine treatment. Hence, immuno-electron histochemistry of TH was employed to investigate adrenergic termination to the m...

OBJECTIVE: To compare sonographic parameters related to the urethrovesical junction and proximal urethra in cured and not cured patients surgically treated with the Burch technique, for establishing a possible correlation with prognostic factors. MATERIALS AND METHODS: Thirty female patients were selected and divided into two groups: 15 patients considered as clinically cured and 15 not cured. ...

Mucocoele or mucoid cyst may occur in any part of the urethra and is usually asymptomatic. McCrea (1940), quoting Ottow, explains the origin of these cysts on the assumption that the lips of the primitive urethral opening have failed to unite in their entirety. If this failure is confined to the urethral epithelium, a mucoid cyst or mucocoele results. A case is presented below in which the situ...

BACKGROUND Numerous studies indicated that Intravesical prostatic protrusion is relevant to prognosis of LUTS, however, the confounding effect that is brought about by prostate volume, urethra anterior curvature angle and other factors makes it hard to evaluate the role of intravesical prostatic protrusion in clinical observation. METHODS We proposed a fluid structural interaction analysis ap...

Disorders of sex development (DSDs) are congenital anomalies that affect sexual differentiation of genitourinary organs and secondary sex characters. A common cause of female genital virilization is congenital adrenal hyperplasia (CAH), in which excess androgen production during development of 46XX females can result in vaginal atresia, masculinization of the urethra, a single urogenital sinus,...

The male urethral sphincter is a striated muscle in contact with the urethra from the base of the bladder to the perineal membrane. The individual muscle fibers are 25 to 30% smaller than fibers of associated muscles and are embedded in connective tissue which obscures the visibility of the whole muscle. The muscle primordium is laid down around the urethra prior to the development of the prost...

Radical prostatectomy is a common treatment for patients with prostate cancer [1]. The current surgical technique for radical prostatectomies requires dividing the urethra from the bladder in order to aid the removal of the prostate [2]. At the end of a prostatectomy, the urethra is reconnected to the bladder in a procedure known as urethrovesical anastomosis (UVA) involving suturing the urethr...

AIM To investigate the feasibility of the autologous fascia graft in urethra defect reconstruction. METHODS In 24 adult male rabbits, a standardized defect (17 mm) was created within the midportion of each urethra. Two-cm long fascial tube grafts were interposed between the cut ends of the urethra. Twenty-four rabbits were divided into 12 groups. At 0, 3, 10, 15, 21, 30, 45, 60, 90, 120, 150,...
