The prostate is a dense fibromuscular gland. Its shape is like an inverted cone having a base above surrounding the neck of the urinary bladder, apex below situated on the external urethral sphincter. Location: The prostate lies directly inferior to the bladder and wraps around the proximal urethra in the lesser pelvis. A fibrous capsule. The normal capacity of the bladder is to mL. During urination, the bladder muscles contract, and two sphincters (valves) open to allow urine to flow out. Urine exits the bladder into the urethra, which carries urine out of the body. Because it passes through the penis, the urethra is longer in men (8 inches) than in women ( inches).
Results of laboratory investigations were within normal limit. On cystourethroscopy, small mass with smooth urothelial covering was present at the bladder neck extending onto proximal urethra [Figure 2]. Mass was extending from 10 o'clock to 2 o'clock position at the bladder neck. Urinary Bladder. The urinary bladder is a temporary storage reservoir for is located in the pelvic cavity, posterior to the symphysis pubis, and below the parietal size and shape of the urinary bladder varies with the amount of urine it contains and with the pressure it receives from surrounding organs.
Prostatic diseases like benign prostatic hyperpla-sia (BPH) and carcinoma of prostate (CaP) are the most common diseases of old age in males, with CaP being the most common cancer in Pakistani men.1 Little is known about the etiology of carcinoma of prostate, but most studies on several risk factors such as age, race, family history, androgens, estrogens and environmental influences have.

The urinary bladder and urethra are pelvic urinary organs whose respective functions are to store and expel urine outside of the body in the act of micturition (urination).
As is the case with most of the pelvic viscera, there are differences between male and female anatomy of the urinary bladder and urethra. In our entire urinary system series, the urinary bladder and urethra represent. Gross Anatomy of the Bladder Surface Anatomy of the Bladder.
The bladder has a volume capacity of – ml and is of ovoid shape. The bladder can be divided in the corpus with two lateral walls, dorsal wall and ventral wall. At the apex, the dorsal and ventral wall meets and the urachus starts and runs to the umbilicus. The bladder neck.

Read these instructions before taking this practice exam. In humans, the bladder is a hollow muscular organ situated at the base of the gross anatomy, the bladder can be divided into a broad fundus, a body, an apex, and a neck.
The apex is directed forward toward the upper part of the pubic symphysis, and from there the median umbilical ligament continues upward on the back of the anterior abdominal wall to the umbilicus. James C. Brown, in Textbook of Veterinary Diagnostic Radiology (Seventh Edition), Anatomy.
The urethra is a tubular organ that serves as an outlet for urine from the urinary bladder and, in the male, semen and reproductive secretions. Anatomically, the male urethra comprises three major areas: the prostatic urethra, membranous urethra, and penile urethra (Fig.
1 Together, the. Anatomy and function of the female urethra. The female urethra begins at the bottom of the bladder, known as the neck. It extends downward, through the muscular area of the pelvic floor. The prostate gland, which lies below the bladder and surrounds the urethra, is the male organ that produces is very common for the prostate gland to start enlarging after the age of 40, although it may not always produce symptoms.
The first noticeable symptoms appear when the enlarged prostate gland presses upon the urethra, causing problems with urination. The scarring can cause the opening between the bladder and urethra to become narrower, resulting in the bladder neck contracture.
Poor blood supply to the anastomosis may be another possible cause. Stitches that are too tight can cut off the blood vessels near the. It is divided into apex, body, fundus, and neck. The bladder can rupture from blunt abdominal trauma, resulting in extravasation of urine and, potentially, peritonitis.
The internal urethral sphincter is a circular smooth muscle that surrounds the neck of the bladder and prevents urine leakage. The bladder neck and proximal urethra constitute the female internal sphincter.
However, female external sphincter (ie, rhabdosphincter) has the most prominent effect on the female urethra. This occurs at the urogenital triangle, located approximately cm distal to the bladder neck, and affects approximately cm of urethral length.
itself. The area where the urethra joins the bladder is the bladder neck. The bladder neck, composed of the second set of muscles known as the internal sphincter, helps urine stay in the bladder.
The third set of muscles is the pelvic floor muscles, also referred to as the external sphincter, which surround and support the urethra. Bladder neck contractures are generally initially managed with urethral dilation or an incision of the bladder, a type of internal urethotomy procedure called transurethral incision of a bladder neck contracture (TUIBN) This incision can be performed with a small knife that fits through the scope, or.
The bladder can stretch and distend to a normal capacity of mls. The bladder acts as a storage reservoir for urine. Micturition is the process by which urine is expelled from the bladder. At the base of the bladder is the bladder neck, which leads into the urethra, through which urine is expelled to the external environment.
Anatomy. The male urethra, composed of a mucosa and submucosa, is approximately 20 cm in length and extends from the neck of the bladder to the external meatus of the glans penis.
The prostatic urethra begins at the bladder neck and lies within the prostate. It is usually 3 cm long. It is the widest and most readily dilated portion of the urethra. Left: Voiding cystourethrogram showing bilateral vesicoureteral reflux, a wide-open vesical neck, and severe spasm of the striated urethral sphincter in the mid portion of the urethra (arrow) secondary to distal urethral stenosis.
Right: Postvoiding film. The bladder is empty and the vesical neck open, but the dilated urethra contains. Diagnosis is carried out with the help of radial and endoscopic methods of investigation.
So. When sclerosis of the neck of the bladder on the ascending urethrograms determine the free passage of the urethra to the neck of the bladder; with the stricture of the urethra, constriction is detected in the distal part of the urethra (relative to the neck of the bladder).Neck – formed by the convergence of the fundus and the two inferolateral surfaces.
It is continuous with the urethra. Urine enters the bladder through the left and right ureters, and exits via the urethra. Internally, these orifices are marked by the trigone – a triangular area located within the fundus.Gross anatomy.
The bladder has a triangular shape with a posterior base, an anterior apex and an inferior neck with two inferolateral surfaces. It is lined with a rough, trabeculated transitional cell epithelium except at the trigone.
