Accessory Glands of the Male Reproductive System01:16

Accessory Glands of the Male Reproductive System

The accessory ducts involved in sperm maturation and transportation include the epididymides, vasa deferentia, ejaculatory ducts, and urethra. These ducts play a critical role in the maturation, storage, and transportation of sperm from the testes to the urethra, where it is then released during ejaculation.
The epididymis is a small, comma-shaped organ located at the back of each testicle. The epididymis can be divided into three main parts: the head, body, and tail. The head of the epididymis...
Ureters01:22

Ureters

The ureters are retroperitoneal tubes located on either side of the vertebral column. They are responsible for transporting urine from each kidney to the urinary bladder. These tubes have thick walls and are approximately 25-30 cm long. Their diameter is around 10 mm at the renal pelvis, gradually narrowing to 1 mm as the ureter obliquely enters the posterior bladder wall through the ureteric orifices. The shape of these orifices is slit-like, which helps to prevent urine backflow toward the...
Urethra01:16

Urethra

The urethra is a hollowed tubular organ through which urine is expelled from the body. This structure extends from the bladder to the external opening, allowing urine to be released.
The anatomy of the urethra differs between males and females. In females, the urethra is short, measuring about 3–4 cm in length, and opens anterior to the vaginal opening. In males, the urethra is longer and passes through the penis, serving dual purposes: expelling urine and ejaculating semen. The male urethra is...

Anatomy of the Genitourinary System II: Bladder and Urethra

The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...
Penis01:29

Penis

The penis serves a dual role in sexual reproduction and urination. It consists of three main regions: the glans penis, the body, and the root, each with distinct functions and unique anatomical features.
Anatomy of the Penis
The glans penis, or the head, is the terminal part of the penis and houses the external urethral orifice, the exit point for urine and semen. Covered by the prepuce, or foreskin, the glans is noted for its sensitivity and plays a key role in sexual pleasure. The body of the...
Urinary Bladder01:23

Urinary Bladder

The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

Summary

Anatomical variations of the prostatic utricle (PU) were clarified through dissection and 3D modeling. Understanding these PU variations is crucial for diagnosing and treating related anomalies.

Area of Science:

  • Anatomy
  • Urology

Background:

  • Anatomical variations of the prostatic utricle (PU) are infrequently documented.
  • Knowledge of PU variations is essential for diagnosing and treating PU anomalies.

Purpose of the Study:

  • To clarify the anatomical variations of the prostatic utricle.
  • To provide insights for improved diagnosis and treatment of PU diseases.

Main Methods:

  • Dissection of 50 prostates under surgical microscopy.
  • Ultrasonography and dissection of 5 prostates.
  • Light microscopy and 3D reconstruction of 2 prostates.

Main Results:

  • The prostatic utricle (PU) was classified into three types based on pouch location.
  • The most common PU type projected from between the ejaculatory ducts.
  • Diverse sites and shapes of the utricular orifice were observed on the seminal colliculus.

Conclusions:

  • This study elucidated prostatic utricle anatomical variations.
  • Findings may enhance the diagnosis and treatment of prostatic utricle diseases.
